AWS Site-to-Site VPN is a fully-managed service that creates a secure connection between your data center or branch office and your AWS resources using IP Security (IPSec) tunnels. When using Site-to-Site VPN, you can connect to both your Amazon Virtual Private Clouds (VPC) as well as AWS Transit Gateway, and two tunnels per connection are used for increased redundancy. For globally distributed applications, the Accelerated Site-to-Site VPN option provides even greater performance by working with AWS Global Accelerator to intelligently route your traffic to the nearest AWS network endpoint with the best performance. Play Benefits Highly available AWS Site-to-Site VPN delivers high availability by using two tunnels across multiple Availability Zones within the AWS global network. You can stream primary traffic through the first tunnel and use the second tunnel for redundancy — if one tunnel goes down, traffic continues to flow. Secure With AWS Site-to-Site VPN, you can connect to an Amazon VPC or AWS Transit Gateway the same way you connect to your on-premises servers. AWS Site-to-Site VPN establishes secure and private sessions using IP Security (IPSec). Accelerate Applications The Accelerated Site-to-Site VPN option improves the performance of your VPN connection by working with AWS Global Accelerator. AWS Global Accelerator is used to intelligently route traffic to the nearest AWS network endpoint with the best performance. Robust monitoring AWS Site-to-Site VPN gives you visibility into local and remote network health, and monitors the reliability and performance of your VPN connections by integrating with Amazon CloudWatch. Use cases Application Migration Moving applications to the cloud is easier with a Site-to-site VPN connection between your network and the AWS cloud. You can host Amazon VPCs behind your corporate firewall and seamlessly move your IT resources, without changing the way your users access these applications. Secure communication between remote locations You can use AWS Site-to-Site VPN connections to securely communicate between remote sites.

https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/AccessLogs.html | Access logs (standard logs) - Amazon CloudFront Access logs (standard logs) - Amazon CloudFront Documentation Amazon CloudFront Developer Guide Access logs (standard logs) You can configure CloudFront to create log files that contain detailed information about every user (viewer) request that CloudFront receives. These are called access logs , also known as standard logs . Each log contains information such as the time the request was received, the processing time, request paths, and server responses. You can use these access logs to analyze response times and to troubleshoot issues. The following diagram shows how CloudFront logs information about requests for your objects. In this example, the distributions are configured to send access logs to an Amazon S3 bucket. In this example, you have two websites, A and B, and two corresponding CloudFront distributions. Users request your objects using URLs that are associated with your distributions. CloudFront routes each request to the appropriate edge location. CloudFront writes data about each request to a log file specific to that distribution. In this example, information about requests related to Distribution A goes into a log file for Distribution A. Information about requests related to Distribution B goes into a log file for Distribution B. CloudFront periodically saves the log file for a distribution in the Amazon S3 bucket that you specified when you enabled logging. CloudFront then starts saving information about subsequent requests in a new log file for the distribution. If viewers don't access your content during a given hour, you don't receive any log files for that hour. Note We recommend that you use the logs to understand the nature of the requests for your content, not as a complete accounting of all requests. CloudFront delivers access logs on a best-effort basis. The log entry for a particular request might be delivered long after the request was actually processed and, in rare cases, a log entry might not be delivered at all. When a log entry is omitted from access logs, the number of entries in the access logs won't match the usage that appears in the AWS billing and usage reports. CloudFront supports two versions of standard logging. Standard logging (legacy) supports sending your access logs to Amazon S3 only . Standard logging (v2) supports additional delivery destinations. You can configure both or either logging option for your distribution. For more information, see the following topics: Topics Configure standard logging (v2) Configure standard logging (legacy) Standard logging reference Tip CloudFront also offers real-time access logs, which give you information about requests made to a distribution in real time (logs are delivered within seconds of receiving the requests). You can use real-time access logs to monitor, analyze, and take action based on content delivery performance. For more information, see Use real-time access logs .

https://docs.aws.amazon.com/de_de/AmazonCloudFront/latest/DeveloperGuide/AccessLogs.html | Zugriffsprotokolle (Standardprotokolle) - Amazon CloudFront Zugriffsprotokolle (Standardprotokolle) - Amazon CloudFront Dokumentation Amazon CloudFront Entwicklerhandbuch Die vorliegende Übersetzung wurde maschinell erstellt. Im Falle eines Konflikts oder eines Widerspruchs zwischen dieser übersetzten Fassung und der englischen Fassung (einschließlich infolge von Verzögerungen bei der Übersetzung) ist die englische Fassung maßgeblich. Zugriffsprotokolle (Standardprotokolle) Sie können so konfigurieren CloudFront , dass Protokolldateien erstellt werden, die detaillierte Informationen zu jeder CloudFront empfangenen Benutzeranfrage (Viewer-Anfrage) enthalten. Diese werden als Zugriffsprotokolle bezeichnet, die auch als Standardprotokolle bezeichnet werden. Jedes Protokoll enthält Informationen wie die Zeit, zu der die Anforderung einging, Verarbeitungszeit, Anforderungspfade und Serverantworten. Sie können diese Zugriffsprotokolle verwenden, um Antwortzeiten zu analysieren und Probleme zu beheben. Das folgende Diagramm zeigt, wie Informationen über Anfragen für Ihre Objekte CloudFront protokolliert werden. In diesem Beispiel sind die Distributionen so konfiguriert, dass sie Zugriffsprotokolle an einen Amazon S3-Bucket senden. In diesem Beispiel haben Sie zwei Websites, A und B, und zwei entsprechende CloudFront Distributionen. Benutzer fordern Ihre Objekte an URLs , die mit Ihren Distributionen verknüpft sind. CloudFront leitet jede Anfrage an den entsprechenden Edge-Standort weiter. CloudFront schreibt Daten zu jeder Anfrage in eine Protokolldatei, die für diese Verteilung spezifisch ist. In diesem Beispiel werden Informationen zu Anforderungen mit Bezug auf Distribution A in einer Protokolldatei für Distribution A gespeichert. Informationen zu Anforderungen mit Bezug auf Distribution B werden in einer Protokolldatei für Distribution B gespeichert. CloudFront speichert regelmäßig die Protokolldatei für eine Distribution im Amazon S3 S3-Bucket, den Sie bei der Aktivierung der Protokollierung angegeben haben. CloudFront beginnt dann, Informationen über nachfolgende Anfragen in einer neuen Protokolldatei für die Verteilung zu speichern. Wenn Viewer eine Stunde lang nicht auf Ihre Inhalte zugreifen, erhalten Sie für diesen Zeitraum auch keine Protokolldateien. Anmerkung Wir empfehlen Ihnen, die Protokolle zu verwenden, um die Art der Anfragen nach Ihren Inhalten zu verstehen, und nicht, um alle Anfragen vollständig zu erfassen. CloudFront stellt Zugriffsprotokolle nach bestem Wissen und Gewissen bereit. Der Protokolleintrag für eine bestimmte Anfrage wird möglicherweise viel später übermittelt, als die Anfrage tatsächlich verarbeitet wurde; in seltenen Fällen kann es auch sein, dass ein Protokolleintrag gar nicht übermittelt wird. Wenn ein Protokolleintrag nicht in den Zugriffsprotokollen enthalten ist, stimmt die Anzahl der Einträge in den Zugriffsprotokollen nicht mit deren Anzahl in den Abrechnungs- und Nutzungsberichten für AWS überein. CloudFront unterstützt zwei Versionen der Standardprotokollierung. Die Standardprotokollierung (Legacy) unterstützt nur das Senden Ihrer Zugriffsprotokolle an Amazon S3. Die Standardprotokollierung (v2) unterstützt zusätzliche Bereitstellungsziele. Sie können beide oder eine der beiden Protokollierungsoptionen für Ihre Distribution konfigurieren. Weitere Informationen finden Sie unter den folgenden Themen: Themen Konfigurieren der Standardprotokollierung (v2) Konfigurieren der Standardprotokollierung (Legacy) Referenz zur Standardprotokollierung Tipp CloudFront bietet auch Echtzeit-Zugriffsprotokolle, die Ihnen Informationen über Anfragen an eine Distribution in Echtzeit liefern (Protokolle werden innerhalb von Sekunden nach Erhalt der Anfragen zugestellt). Sie können Zugriffsprotokolle in Echtzeit verwenden, um die Leistung der Inhaltsbereitstellung zu überwachen, zu analysieren und Maßnahmen zu ergreifen. Weitere Informationen finden Sie unter Verwenden Sie Zugriffsprotokolle in Echtzeit . JavaScript ist in Ihrem Browser nicht verfügbar oder deaktiviert.

https://pubs.opengroup.org/onlinepubs/9799919799/functions/aio_suspend.html#top | aio_suspend <<< Previous Home Next >>> The Open Group Base Specifications Issue 8 IEEE Std 1003.1-2024 Copyright © 2001-2024 The IEEE and The Open Group NAME aio_suspend — wait for an asynchronous I/O request SYNOPSIS #include < aio.h > int aio_suspend(const struct aiocb *const list [], int nent , const struct timespec * timeout ); DESCRIPTION The aio_suspend () function shall suspend the calling thread until at least one of the asynchronous I/O operations referenced by the list argument has completed, until a signal interrupts the function, or, if timeout is not NULL, until the time interval specified by timeout has passed. If any of the aiocb structures in the list correspond to completed asynchronous I/O operations (that is, the error status for the operation is not equal to [EINPROGRESS]) at the time of the call, the function shall return without suspending the calling thread. The list argument is an array of pointers to asynchronous I/O control blocks. The nent argument indicates the number of elements in the array. Each aiocb structure pointed to has been used in initiating an asynchronous I/O request via aio_read () , aio_write () , or lio_listio () . This array may contain null pointers, which are ignored. If this array contains pointers that refer to aiocb structures that have not been used in submitting asynchronous I/O, the effect is undefined. If the time interval indicated in the timespec structure pointed to by timeout passes before any of the I/O operations referenced by list are completed, then aio_suspend () shall return with an error. The clock that is used to measure this time interval shall be the CLOCK_MONOTONIC clock. RETURN VALUE If the aio_suspend () function returns after one or more asynchronous I/O operations have completed, the function shall return zero. Otherwise, the function shall return a value of -1 and set errno to indicate the error. The application may determine which asynchronous I/O completed by scanning the associated error and return status using aio_error () and aio_return () , respectively. ERRORS The aio_suspend () function shall fail if: [EAGAIN] No asynchronous I/O indicated in the list referenced by list completed in the time interval indicated by timeout . [EINTR] A signal interrupted the aio_suspend () function. Note that, since each asynchronous I/O operation may possibly provoke a signal when it completes, this error return may be caused by the completion of one (or more) of the very I/O operations being awaited. The following sections are informative. EXAMPLES None. APPLICATION USAGE None. RATIONALE None. FUTURE DIRECTIONS None. SEE ALSO aio_read () , aio_write () , lio_listio () XBD <aio.h> CHANGE HISTORY First released in Issue 5. Included for alignment with the POSIX Realtime Extension. Issue 6 The [ENOSYS] error condition has been removed as stubs need not be provided if an implementation does not support the Asynchronous Input and Output option. The APPLICATION USAGE section is added. The DESCRIPTION is updated for alignment with IEEE Std 1003.1j-2000 by specifying that the CLOCK_MONOTONIC clock, if supported, is used. Issue 7 The aio_suspend () function is moved from the Asynchronous Input and Output option to the Base. Issue 8 Austin Group Defect 1346 is applied, requiring support for Monotonic Clock.

http://anh.cs.luc.edu/handsonPythonTutorial/ifstatements.html#congressex | 3.1. If Statements — Hands-on Python Tutorial for Python 3 Navigation index next | previous | Hands-on Python Tutorial » 3. More On Flow of Control » 3.1. If Statements ¶ 3.1.1. Simple Conditions ¶ The statements introduced in this chapter will involve tests or conditions . More syntax for conditions will be introduced later, but for now consider simple arithmetic comparisons that directly translate from math into Python. Try each line separately in the Shell 2 < 5 3 > 7 x = 11 x > 10 2 * x < x type ( True ) You see that conditions are either True or False . These are the only possible Boolean values (named after 19th century mathematician George Boole). In Python the name Boolean is shortened to the type bool . It is the type of the results of true-false conditions or tests. Note The Boolean values True and False have no quotes around them! Just as '123' is a string and 123 without the quotes is not, 'True' is a string, not of type bool. 3.1.2. Simple if Statements ¶ Run this example program, suitcase.py. Try it at least twice, with inputs: 30 and then 55. As you an see, you get an extra result, depending on the input. The main code is: weight = float ( input ( "How many pounds does your suitcase weigh? " )) if weight > 50 : print ( "There is a $25 charge for luggage that heavy." ) print ( "Thank you for your business." ) The middle two line are an if statement. It reads pretty much like English. If it is true that the weight is greater than 50, then print the statement about an extra charge. If it is not true that the weight is greater than 50, then don’t do the indented part: skip printing the extra luggage charge. In any event, when you have finished with the if statement (whether it actually does anything or not), go on to the next statement that is not indented under the if . In this case that is the statement printing “Thank you”. The general Python syntax for a simple if statement is if condition : indentedStatementBlock If the condition is true, then do the indented statements. If the condition is not true, then skip the indented statements. Another fragment as an example: if balance < 0 : transfer = - balance # transfer enough from the backup account: backupAccount = backupAccount - transfer balance = balance + transfer As with other kinds of statements with a heading and an indented block, the block can have more than one statement. The assumption in the example above is that if an account goes negative, it is brought back to 0 by transferring money from a backup account in several steps. In the examples above the choice is between doing something (if the condition is True ) or nothing (if the condition is False ). Often there is a choice of two possibilities, only one of which will be done, depending on the truth of a condition. 3.1.3. if - else Statements ¶ Run the example program, clothes.py . Try it at least twice, with inputs 50 and then 80. As you can see, you get different results, depending on the input. The main code of clothes.py is: temperature = float ( input ( 'What is the temperature? ' )) if temperature > 70 : print ( 'Wear shorts.' ) else : print ( 'Wear long pants.' ) print ( 'Get some exercise outside.' ) The middle four lines are an if-else statement. Again it is close to English, though you might say “otherwise” instead of “else” (but else is shorter!). There are two indented blocks: One, like in the simple if statement, comes right after the if heading and is executed when the condition in the if heading is true. In the if - else form this is followed by an else: line, followed by another indented block that is only executed when the original condition is false . In an if - else statement exactly one of two possible indented blocks is executed. A line is also shown de dented next, removing indentation, about getting exercise. Since it is dedented, it is not a part of the if-else statement: Since its amount of indentation matches the if heading, it is always executed in the normal forward flow of statements, after the if - else statement (whichever block is selected). The general Python if - else syntax is if condition : indentedStatementBlockForTrueCondition else: indentedStatementBlockForFalseCondition These statement blocks can have any number of statements, and can include about any kind of statement. See Graduate Exercise 3.1.4. More Conditional Expressions ¶ All the usual arithmetic comparisons may be made, but many do not use standard mathematical symbolism, mostly for lack of proper keys on a standard keyboard. Meaning Math Symbol Python Symbols Less than < < Greater than > > Less than or equal ≤ <= Greater than or equal ≥ >= Equals = == Not equal ≠ != There should not be space between the two-symbol Python substitutes. Notice that the obvious choice for equals , a single equal sign, is not used to check for equality. An annoying second equal sign is required. This is because the single equal sign is already used for assignment in Python, so it is not available for tests. Warning It is a common error to use only one equal sign when you mean to test for equality, and not make an assignment! Tests for equality do not make an assignment, and they do not require a variable on the left. Any expressions can be tested for equality or inequality ( != ). They do not need to be numbers! Predict the results and try each line in the Shell : x = 5 x x == 5 x == 6 x x != 6 x = 6 6 == x 6 != x 'hi' == 'h' + 'i' 'HI' != 'hi' [ 1 , 2 ] != [ 2 , 1 ] An equality check does not make an assignment. Strings are case sensitive. Order matters in a list. Try in the Shell : 'a' > 5 When the comparison does not make sense, an Exception is caused. [1] Following up on the discussion of the inexactness of float arithmetic in String Formats for Float Precision , confirm that Python does not consider .1 + .2 to be equal to .3: Write a simple condition into the Shell to test. Here is another example: Pay with Overtime. Given a person’s work hours for the week and regular hourly wage, calculate the total pay for the week, taking into account overtime. Hours worked over 40 are overtime, paid at 1.5 times the normal rate. This is a natural place for a function enclosing the calculation. Read the setup for the function: def calcWeeklyWages ( totalHours , hourlyWage ): '''Return the total weekly wages for a worker working totalHours, with a given regular hourlyWage. Include overtime for hours over 40. ''' The problem clearly indicates two cases: when no more than 40 hours are worked or when more than 40 hours are worked. In case more than 40 hours are worked, it is convenient to introduce a variable overtimeHours. You are encouraged to think about a solution before going on and examining mine. You can try running my complete example program, wages.py, also shown below. The format operation at the end of the main function uses the floating point format ( String Formats for Float Precision ) to show two decimal places for the cents in the answer: def calcWeeklyWages ( totalHours , hourlyWage ): '''Return the total weekly wages for a worker working totalHours, with a given regular hourlyWage. Include overtime for hours over 40. ''' if totalHours <= 40 : totalWages = hourlyWage * totalHours else : overtime = totalHours - 40 totalWages = hourlyWage * 40 + ( 1.5 * hourlyWage ) * overtime return totalWages def main (): hours = float ( input ( 'Enter hours worked: ' )) wage = float ( input ( 'Enter dollars paid per hour: ' )) total = calcWeeklyWages ( hours , wage ) print ( 'Wages for {hours} hours at ${wage:.2f} per hour are ${total:.2f}.' . format ( ** locals ())) main () Here the input was intended to be numeric, but it could be decimal so the conversion from string was via float , not int . Below is an equivalent alternative version of the body of calcWeeklyWages , used in wages1.py . It uses just one general calculation formula and sets the parameters for the formula in the if statement. There are generally a number of ways you might solve the same problem! if totalHours <= 40 : regularHours = totalHours overtime = 0 else : overtime = totalHours - 40 regularHours = 40 return hourlyWage * regularHours + ( 1.5 * hourlyWage ) * overtime The in boolean operator : There are also Boolean operators that are applied to types others than numbers. A useful Boolean operator is in , checking membership in a sequence: >>> vals = [ 'this' , 'is' , 'it] >>> 'is' in vals True >>> 'was' in vals False It can also be used with not , as not in , to mean the opposite: >>> vals = [ 'this' , 'is' , 'it] >>> 'is' not in vals False >>> 'was' not in vals True In general the two versions are: item in sequence item not in sequence Detecting the need for if statements : Like with planning programs needing``for`` statements, you want to be able to translate English descriptions of problems that would naturally include if or if - else statements. What are some words or phrases or ideas that suggest the use of these statements? Think of your own and then compare to a few I gave: [2] 3.1.4.1. Graduate Exercise ¶ Write a program, graduate.py , that prompts students for how many credits they have. Print whether of not they have enough credits for graduation. (At Loyola University Chicago 120 credits are needed for graduation.) 3.1.4.2. Head or Tails Exercise ¶ Write a program headstails.py . It should include a function flip() , that simulates a single flip of a coin: It randomly prints either Heads or Tails . Accomplish this by choosing 0 or 1 arbitrarily with random.randrange(2) , and use an if - else statement to print Heads when the result is 0, and Tails otherwise. In your main program have a simple repeat loop that calls flip() 10 times to test it, so you generate a random sequence of 10 Heads and Tails . 3.1.4.3. Strange Function Exercise ¶ Save the example program jumpFuncStub.py as jumpFunc.py , and complete the definitions of functions jump and main as described in the function documentation strings in the program. In the jump function definition use an if - else statement (hint [3] ). In the main function definition use a for -each loop, the range function, and the jump function. The jump function is introduced for use in Strange Sequence Exercise , and others after that. 3.1.5. Multiple Tests and if - elif Statements ¶ Often you want to distinguish between more than two distinct cases, but conditions only have two possible results, True or False , so the only direct choice is between two options. As anyone who has played “20 Questions” knows, you can distinguish more cases by further questions. If there are more than two choices, a single test may only reduce the possibilities, but further tests can reduce the possibilities further and further. Since most any kind of statement can be placed in an indented statement block, one choice is a further if statement. For instance consider a function to convert a numerical grade to a letter grade, ‘A’, ‘B’, ‘C’, ‘D’ or ‘F’, where the cutoffs for ‘A’, ‘B’, ‘C’, and ‘D’ are 90, 80, 70, and 60 respectively. One way to write the function would be test for one grade at a time, and resolve all the remaining possibilities inside the next else clause: def letterGrade ( score ): if score >= 90 : letter = 'A' else : # grade must be B, C, D or F if score >= 80 : letter = 'B' else : # grade must be C, D or F if score >= 70 : letter = 'C' else : # grade must D or F if score >= 60 : letter = 'D' else : letter = 'F' return letter This repeatedly increasing indentation with an if statement as the else block can be annoying and distracting. A preferred alternative in this situation, that avoids all this indentation, is to combine each else and if block into an elif block: def letterGrade ( score ): if score >= 90 : letter = 'A' elif score >= 80 : letter = 'B' elif score >= 70 : letter = 'C' elif score >= 60 : letter = 'D' else : letter = 'F' return letter The most elaborate syntax for an if - elif - else statement is indicated in general below: if condition1 : indentedStatementBlockForTrueCondition1 elif condition2 : indentedStatementBlockForFirstTrueCondition2 elif condition3 : indentedStatementBlockForFirstTrueCondition3 elif condition4 : indentedStatementBlockForFirstTrueCondition4 else: indentedStatementBlockForEachConditionFalse The if , each elif , and the final else lines are all aligned. There can be any number of elif lines, each followed by an indented block. (Three happen to be illustrated above.) With this construction exactly one of the indented blocks is executed. It is the one corresponding to the first True condition, or, if all conditions are False , it is the block after the final else line. Be careful of the strange Python contraction. It is elif , not elseif . A program testing the letterGrade function is in example program grade1.py . See Grade Exercise . A final alternative for if statements: if - elif -.... with no else . This would mean changing the syntax for if - elif - else above so the final else: and the block after it would be omitted. It is similar to the basic if statement without an else , in that it is possible for no indented block to be executed. This happens if none of the conditions in the tests are true. With an else included, exactly one of the indented blocks is executed. Without an else , at most one of the indented blocks is executed. if weight > 120 : print ( 'Sorry, we can not take a suitcase that heavy.' ) elif weight > 50 : print ( 'There is a $25 charge for luggage that heavy.' ) This if - elif statement only prints a line if there is a problem with the weight of the suitcase. 3.1.5.1. Sign Exercise ¶ Write a program sign.py to ask the user for a number. Print out which category the number is in: 'positive' , 'negative' , or 'zero' . 3.1.5.2. Grade Exercise ¶ In Idle, load grade1.py and save it as grade2.py Modify grade2.py so it has an equivalent version of the letterGrade function that tests in the opposite order, first for F, then D, C, .... Hint: How many tests do you need to do? [4] Be sure to run your new version and test with different inputs that test all the different paths through the program. Be careful to test around cut-off points. What does a grade of 79.6 imply? What about exactly 80? 3.1.5.3. Wages Exercise ¶ * Modify the wages.py or the wages1.py example to create a program wages2.py that assumes people are paid double time for hours over 60. Hence they get paid for at most 20 hours overtime at 1.5 times the normal rate. For example, a person working 65 hours with a regular wage of $10 per hour would work at $10 per hour for 40 hours, at 1.5 * $10 for 20 hours of overtime, and 2 * $10 for 5 hours of double time, for a total of 10*40 + 1.5*10*20 + 2*10*5 = $800. You may find wages1.py easier to adapt than wages.py . Be sure to test all paths through the program! Your program is likely to be a modification of a program where some choices worked before, but once you change things, retest for all the cases! Changes can mess up things that worked before. 3.1.6. Nesting Control-Flow Statements ¶ The power of a language like Python comes largely from the variety of ways basic statements can be combined . In particular, for and if statements can be nested inside each other’s indented blocks. For example, suppose you want to print only the positive numbers from an arbitrary list of numbers in a function with the following heading. Read the pieces for now. def printAllPositive ( numberList ): '''Print only the positive numbers in numberList.''' For example, suppose numberList is [3, -5, 2, -1, 0, 7] . You want to process a list, so that suggests a for -each loop, for num in numberList : but a for -each loop runs the same code body for each element of the list, and we only want print ( num ) for some of them. That seems like a major obstacle, but think closer at what needs to happen concretely. As a human, who has eyes of amazing capacity, you are drawn immediately to the actual correct numbers, 3, 2, and 7, but clearly a computer doing this systematically will have to check every number. In fact, there is a consistent action required: Every number must be tested to see if it should be printed. This suggests an if statement, with the condition num > 0 . Try loading into Idle and running the example program onlyPositive.py , whose code is shown below. It ends with a line testing the function: def printAllPositive ( numberList ): '''Print only the positive numbers in numberList.''' for num in numberList : if num > 0 : print ( num ) printAllPositive ([ 3 , - 5 , 2 , - 1 , 0 , 7 ]) This idea of nesting if statements enormously expands the possibilities with loops. Now different things can be done at different times in loops, as long as there is a consistent test to allow a choice between the alternatives. Shortly, while loops will also be introduced, and you will see if statements nested inside of them, too. The rest of this section deals with graphical examples. Run example program bounce1.py . It has a red ball moving and bouncing obliquely off the edges. If you watch several times, you should see that it starts from random locations. Also you can repeat the program from the Shell prompt after you have run the script. For instance, right after running the program, try in the Shell bounceBall ( - 3 , 1 ) The parameters give the amount the shape moves in each animation step. You can try other values in the Shell , preferably with magnitudes less than 10. For the remainder of the description of this example, read the extracted text pieces. The animations before this were totally scripted, saying exactly how many moves in which direction, but in this case the direction of motion changes with every bounce. The program has a graphic object shape and the central animation step is shape . move ( dx , dy ) but in this case, dx and dy have to change when the ball gets to a boundary. For instance, imagine the ball getting to the left side as it is moving to the left and up. The bounce obviously alters the horizontal part of the motion, in fact reversing it, but the ball would still continue up. The reversal of the horizontal part of the motion means that the horizontal shift changes direction and therefore its sign: dx = - dx but dy does not need to change. This switch does not happen at each animation step, but only when the ball reaches the edge of the window. It happens only some of the time - suggesting an if statement. Still the condition must be determined. Suppose the center of the ball has coordinates (x, y). When x reaches some particular x coordinate, call it xLow, the ball should bounce. The edge of the window is at coordinate 0, but xLow should not be 0, or the ball would be half way off the screen before bouncing! For the edge of the ball to hit the edge of the screen, the x coordinate of the center must be the length of the radius away, so actually xLow is the radius of the ball. Animation goes quickly in small steps, so I cheat. I allow the ball to take one (small, quick) step past where it really should go ( xLow ), and then we reverse it so it comes back to where it belongs. In particular if x < xLow : dx = - dx There are similar bounding variables xHigh , yLow and yHigh , all the radius away from the actual edge coordinates, and similar conditions to test for a bounce off each possible edge. Note that whichever edge is hit, one coordinate, either dx or dy, reverses. One way the collection of tests could be written is if x < xLow : dx = - dx if x > xHigh : dx = - dx if y < yLow : dy = - dy if y > yHigh : dy = - dy This approach would cause there to be some extra testing: If it is true that x < xLow , then it is impossible for it to be true that x > xHigh , so we do not need both tests together. We avoid unnecessary tests with an elif clause (for both x and y): if x < xLow : dx = - dx elif x > xHigh : dx = - dx if y < yLow : dy = - dy elif y > yHigh : dy = - dy Note that the middle if is not changed to an elif , because it is possible for the ball to reach a corner , and need both dx and dy reversed. The program also uses several methods to read part of the state of graphics objects that we have not used in examples yet. Various graphics objects, like the circle we are using as the shape, know their center point, and it can be accessed with the getCenter() method. (Actually a clone of the point is returned.) Also each coordinate of a Point can be accessed with the getX() and getY() methods. This explains the new features in the central function defined for bouncing around in a box, bounceInBox . The animation arbitrarily goes on in a simple repeat loop for 600 steps. (A later example will improve this behavior.) def bounceInBox ( shape , dx , dy , xLow , xHigh , yLow , yHigh ): ''' Animate a shape moving in jumps (dx, dy), bouncing when its center reaches the low and high x and y coordinates. ''' delay = . 005 for i in range ( 600 ): shape . move ( dx , dy ) center = shape . getCenter () x = center . getX () y = center . getY () if x < xLow : dx = - dx elif x > xHigh : dx = - dx if y < yLow : dy = - dy elif y > yHigh : dy = - dy time . sleep ( delay ) The program starts the ball from an arbitrary point inside the allowable rectangular bounds. This is encapsulated in a utility function included in the program, getRandomPoint . The getRandomPoint function uses the randrange function from the module random . Note that in parameters for both the functions range and randrange , the end stated is past the last value actually desired: def getRandomPoint ( xLow , xHigh , yLow , yHigh ): '''Return a random Point with coordinates in the range specified.''' x = random . randrange ( xLow , xHigh + 1 ) y = random . randrange ( yLow , yHigh + 1 ) return Point ( x , y ) The full program is listed below, repeating bounceInBox and getRandomPoint for completeness. Several parts that may be useful later, or are easiest to follow as a unit, are separated out as functions. Make sure you see how it all hangs together or ask questions! ''' Show a ball bouncing off the sides of the window. ''' from graphics import * import time , random def bounceInBox ( shape , dx , dy , xLow , xHigh , yLow , yHigh ): ''' Animate a shape moving in jumps (dx, dy), bouncing when its center reaches the low and high x and y coordinates.

Short String Exercise ¶ Write a program short.py with a function printShort with heading: def printShort ( strings ): '''Given a list of strings, print the ones with at most three characters. >>> printShort(['a', 'long', one']) a one ''' In your main program, test the function, calling it several times with different lists of strings. Hint: Find the length of each string with the len function. The function documentation here models a common approach: illustrating the behavior of the function with a Python Shell interaction. This part begins with a line starting with >>> . Other exercises and examples will also document behavior in the Shell. 3.1.6.2. Even Print Exercise ¶ Write a program even1.py with a function printEven with heading: def printEven ( nums ): '''Given a list of integers nums, print the even ones. >>> printEven([4, 1, 3, 2, 7]) 4 2 ''' In your main program, test the function, calling it several times with different lists of integers. Hint: A number is even if its remainder, when dividing by 2, is 0. 3.1.6.3. Even List Exercise ¶ Write a program even2.py with a function chooseEven with heading: def chooseEven ( nums ): '''Given a list of integers, nums, return a list containing only the even ones. >>> chooseEven([4, 1, 3, 2, 7]) [4, 2] ''' In your main program, test the function, calling it several times with different lists of integers and printing the results in the main program. (The documentation string illustrates the function call in the Python shell, where the return value is automatically printed. Remember, that in a program, you only print what you explicitly say to print.) Hint: In the function, create a new list, and append the appropriate numbers to it, before returning the result. 3.1.6.4. Unique List Exercise ¶ * The madlib2.py program has its getKeys function, which first generates a list of each occurrence of a cue in the story format. This gives the cues in order, but likely includes repetitions. The original version of getKeys uses a quick method to remove duplicates, forming a set from the list. There is a disadvantage in the conversion, though: Sets are not ordered, so when you iterate through the resulting set, the order of the cues will likely bear no resemblance to the order they first appeared in the list. That issue motivates this problem: Copy madlib2.py to madlib2a.py , and add a function with this heading: def uniqueList ( aList ): ''' Return a new list that includes the first occurrence of each value in aList, and omits later repeats. The returned list should include the first occurrences of values in aList in their original order. >>> vals = ['cat', 'dog', 'cat', 'bug', 'dog', 'ant', 'dog', 'bug'] >>> uniqueList(vals) ['cat', 'dog', 'bug', 'ant'] ''' Hint: Process aList in order. Use the in syntax to only append elements to a new list that are not already in the new list. After perfecting the uniqueList function, replace the last line of getKeys , so it uses uniqueList to remove duplicates in keyList . Check that your madlib2a.py prompts you for cue values in the order that the cues first appear in the madlib format string. 3.1.7. Compound Boolean Expressions ¶ To be eligible to graduate from Loyola University Chicago, you must have 120 credits and a GPA of at least 2.0. This translates directly into Python as a compound condition : credits >= 120 and GPA >= 2.0 This is true if both credits >= 120 is true and GPA >= 2.0 is true. A short example program using this would be: credits = float ( input ( 'How many units of credit do you have? ' )) GPA = float ( input ( 'What is your GPA? ' )) if credits >= 120 and GPA >= 2.0 : print ( 'You are eligible to graduate!' ) else : print ( 'You are not eligible to graduate.' ) The new Python syntax is for the operator and : condition1 and condition2 The compound condition is true if both of the component conditions are true. It is false if at least one of the conditions is false. See Congress Exercise . In the last example in the previous section, there was an if - elif statement where both tests had the same block to be done if the condition was true: if x < xLow : dx = - dx elif x > xHigh : dx = - dx There is a simpler way to state this in a sentence: If x < xLow or x > xHigh, switch the sign of dx. That translates directly into Python: if x < xLow or x > xHigh : dx = - dx The word or makes another compound condition: condition1 or condition2 is true if at least one of the conditions is true. It is false if both conditions are false. This corresponds to one way the word “or” is used in English. Other times in English “or” is used to mean exactly one alternative is true. Warning When translating a problem stated in English using “or”, be careful to determine whether the meaning matches Python’s or . It is often convenient to encapsulate complicated tests inside a function. Think how to complete the function starting: def isInside ( rect , point ): '''Return True if the point is inside the Rectangle rect.''' pt1 = rect . getP1 () pt2 = rect . getP2 () Recall that a Rectangle is specified in its constructor by two diagonally oppose Point s. This example gives the first use in the tutorials of the Rectangle methods that recover those two corner points, getP1 and getP2 . The program calls the points obtained this way pt1 and pt2 . The x and y coordinates of pt1 , pt2 , and point can be recovered with the methods of the Point type, getX() and getY() . Suppose that I introduce variables for the x coordinates of pt1 , point , and pt2 , calling these x-coordinates end1 , val , and end2 , respectively. On first try you might decide that the needed mathematical relationship to test is end1 <= val <= end2 Unfortunately, this is not enough: The only requirement for the two corner points is that they be diagonally opposite, not that the coordinates of the second point are higher than the corresponding coordinates of the first point. It could be that end1 is 200; end2 is 100, and val is 120. In this latter case val is between end1 and end2 , but substituting into the expression above 200 <= 120 <= 100 is False. The 100 and 200 need to be reversed in this case. This makes a complicated situation. Also this is an issue which must be revisited for both the x and y coordinates. I introduce an auxiliary function isBetween to deal with one coordinate at a time. It starts: def isBetween ( val , end1 , end2 ): '''Return True if val is between the ends. The ends do not need to be in increasing order.''' Clearly this is true if the original expression, end1 <= val <= end2 , is true. You must also consider the possible case when the order of the ends is reversed: end2 <= val <= end1 . How do we combine these two possibilities? The Boolean connectives to consider are and and or . Which applies? You only need one to be true, so or is the proper connective: A correct but redundant function body would be: if end1 <= val <= end2 or end2 <= val <= end1 : return True else : return False Check the meaning: if the compound expression is True , return True . If the condition is False , return False – in either case return the same value as the test condition. See that a much simpler and neater version is to just return the value of the condition itself! return end1 <= val <= end2 or end2 <= val <= end1 Note In general you should not need an if - else statement to choose between true and false values! Operate directly on the boolean expression. A side comment on expressions like end1 <= val <= end2 Other than the two-character operators, this is like standard math syntax, chaining comparisons. In Python any number of comparisons can be chained in this way, closely approximating mathematical notation. Though this is good Python, be aware that if you try other high-level languages like Java and C++, such an expression is gibberish. Another way the expression can be expressed (and which translates directly to other languages) is: end1 <= val and val <= end2 So much for the auxiliary function isBetween . Back to the isInside function. You can use the isBetween function to check the x coordinates, isBetween ( point . getX (), p1 . getX (), p2 . getX ()) and to check the y coordinates, isBetween ( point . getY (), p1 . getY (), p2 . getY ()) Again the question arises: how do you combine the two tests? In this case we need the point to be both between the sides and between the top and bottom, so the proper connector is and . Think how to finish the isInside method. Hint: [5] Sometimes you want to test the opposite of a condition. As in English you can use the word not . For instance, to test if a Point was not inside Rectangle Rect, you could use the condition not isInside ( rect , point ) In general, not condition is True when condition is False , and False when condition is True . The example program chooseButton1.py , shown below, is a complete program using the isInside function in a simple application, choosing colors. Pardon the length. Do check it out. It will be the starting point for a number of improvements that shorten it and make it more powerful in the next section. First a brief overview: The program includes the functions isBetween and isInside that have already been discussed. The program creates a number of colored rectangles to use as buttons and also as picture components. Aside from specific data values, the code to create each rectangle is the same, so the action is encapsulated in a function, makeColoredRect . All of this is fine, and will be preserved in later versions. The present main function is long, though. It has the usual graphics starting code, draws buttons and picture elements, and then has a number of code sections prompting the user to choose a color for a picture element. Each code section has a long if - elif - else test to see which button was clicked, and sets the color of the picture element appropriately. '''Make a choice of colors via mouse clicks in Rectangles -- A demonstration of Boolean operators and Boolean functions.''' from graphics import * def isBetween ( x , end1 , end2 ): '''Return True if x is between the ends or equal to either. The ends do not need to be in increasing order.''' return end1 <= x <= end2 or end2 <= x <= end1 def isInside ( point , rect ): '''Return True if the point is inside the Rectangle rect.''' pt1 = rect . getP1 () pt2 = rect . getP2 () return isBetween ( point . getX (), pt1 . getX (), pt2 . getX ()) and \ isBetween ( point . getY (), pt1 . getY (), pt2 . getY ()) def makeColoredRect ( corner , width , height , color , win ): ''' Return a Rectangle drawn in win with the upper left corner and color specified.''' corner2 = corner . clone () corner2 . move ( width , - height ) rect = Rectangle ( corner , corner2 ) rect . setFill ( color ) rect . draw ( win ) return rect def main (): win = GraphWin ( 'pick Colors' , 400 , 400 ) win . yUp () # right side up coordinates redButton = makeColoredRect ( Point ( 310 , 350 ), 80 , 30 , 'red' , win ) yellowButton = makeColoredRect ( Point ( 310 , 310 ), 80 , 30 , 'yellow' , win ) blueButton = makeColoredRect ( Point ( 310 , 270 ), 80 , 30 , 'blue' , win ) house = makeColoredRect ( Point ( 60 , 200 ), 180 , 150 , 'gray' , win ) door = makeColoredRect ( Point ( 90 , 150 ), 40 , 100 , 'white' , win ) roof = Polygon ( Point ( 50 , 200 ), Point ( 250 , 200 ), Point ( 150 , 300 )) roof . setFill ( 'black' ) roof . draw ( win ) msg = Text ( Point ( win . getWidth () / 2 , 375 ), 'Click to choose a house color.' ) msg . draw ( win ) pt = win . getMouse () if isInside ( pt , redButton ): color = 'red' elif isInside ( pt , yellowButton ): color = 'yellow' elif isInside ( pt , blueButton ): color = 'blue' else : color = 'white' house . setFill ( color ) msg . setText ( 'Click to choose a door color.' ) pt = win . getMouse () if isInside ( pt , redButton ): color = 'red' elif isInside ( pt , yellowButton ): color = 'yellow' elif isInside ( pt , blueButton ): color = 'blue' else : color = 'white' door . setFill ( color ) win . promptClose ( msg ) main () The only further new feature used is in the long return statement in isInside . return isBetween ( point . getX (), pt1 . getX (), pt2 . getX ()) and \ isBetween ( point . getY (), pt1 . getY (), pt2 . getY ()) Recall that Python is smart enough to realize that a statement continues to the next line if there is an unmatched pair of parentheses or brackets. Above is another situation with a long statement, but there are no unmatched parentheses on a line. For readability it is best not to make an enormous long line that would run off your screen or paper. Continuing to the next line is recommended. You can make the final character on a line be a backslash ( '\\' ) to indicate the statement continues on the next line. This is not particularly neat, but it is a rather rare situation. Most statements fit neatly on one line, and the creator of Python decided it was best to make the syntax simple in the most common situation. (Many other languages require a special statement terminator symbol like ‘;’ and pay no attention to newlines). Extra parentheses here would not hurt, so an alternative would be return ( isBetween ( point . getX (), pt1 . getX (), pt2 . getX ()) and isBetween ( point . getY (), pt1 . getY (), pt2 . getY ()) ) The chooseButton1.py program is long partly because of repeated code. The next section gives another version involving lists. 3.1.7.1. Congress Exercise ¶ A person is eligible to be a US Senator who is at least 30 years old and has been a US citizen for at least 9 years. Write an initial version of a program congress.py to obtain age and length of citizenship from the user and print out if a person is eligible to be a Senator or not. A person is eligible to be a US Representative who is at least 25 years old and has been a US citizen for at least 7 years. Elaborate your program congress.py so it obtains age and length of citizenship and prints out just the one of the following three statements that is accurate: You are eligible for both the House and Senate. You eligible only for the House. You are ineligible for Congress. 3.1.8. More String Methods ¶ Here are a few more string methods useful in the next exercises, assuming the methods are applied to a string s : s .startswith( pre ) returns True if string s starts with string pre : Both '-123'.startswith('-') and 'downstairs'.startswith('down') are True , but '1 - 2 - 3'.startswith('-') is False . s .endswith( suffix ) returns True if string s ends with string suffix : Both 'whoever'.endswith('ever') and 'downstairs'.endswith('airs') are True , but '1 - 2 - 3'.endswith('-') is False . s .replace( sub , replacement , count ) returns a new string with up to the first count occurrences of string sub replaced by replacement . The replacement can be the empty string to delete sub . For example: s = '-123' t = s . replace ( '-' , '' , 1 ) # t equals '123' t = t . replace ( '-' , '' , 1 ) # t is still equal to '123' u = '.2.3.4.' v = u . replace ( '.' , '' , 2 ) # v equals '23.4.' w = u . replace ( '.' , ' dot ' , 5 ) # w equals '2 dot 3 dot 4 dot ' 3.1.8.1. Article Start Exercise ¶ In library alphabetizing, if the initial word is an article (“The”, “A”, “An”), then it is ignored when ordering entries. Write a program completing this function, and then testing it: def startsWithArticle ( title ): '''Return True if the first word of title is "The", "A" or "An".''' Be careful, if the title starts with “There”, it does not start with an article. What should you be testing for? 3.1.8.2. Is Number String Exercise ¶ ** In the later Safe Number Input Exercise , it will be important to know if a string can be converted to the desired type of number. Explore that here. Save example isNumberStringStub.py as isNumberString.py and complete it. It contains headings and documentation strings for the functions in both parts of this exercise. A legal whole number string consists entirely of digits. Luckily strings have an isdigit method, which is true when a nonempty string consists entirely of digits, so '2397'.isdigit() returns True , and '23a'.isdigit() returns False , exactly corresponding to the situations when the string represents a whole number! In both parts be sure to test carefully. Not only confirm that all appropriate strings return True . Also be sure to test that you return False for all sorts of bad strings. Recognizing an integer string is more involved, since it can start with a minus sign (or not). Hence the isdigit method is not enough by itself. This part is the most straightforward if you have worked on the sections String Indices and String Slices . An alternate approach works if you use the count method from Object Orientation , and some methods from this section. Complete the function isIntStr . Complete the function isDecimalStr , which introduces the possibility of a decimal point (though a decimal point is not required). The string methods mentioned in the previous part remain useful. [1] This is an improvement that is new in Python 3. [2] “In this case do ___; otherwise”, “if ___, then”, “when ___ is true, then”, “___ depends on whether”, [3] If you divide an even number by 2, what is the remainder? Use this idea in your if condition. [4] 4 tests to distinguish the 5 cases, as in the previous version [5] Once again, you are calculating and returning a Boolean result. You do not need an if - else statement. Table Of Contents 3.1. If Statements 3.1.1. Simple Conditions 3.1.2. Simple if Statements 3.1.3. if - else Statements 3.1.4.

https://docs.aws.amazon.com/es_es/AmazonCloudFront/latest/DeveloperGuide/AccessLogs.html | Registros estándar (registros de acceso) - Amazon CloudFront Registros estándar (registros de acceso) - Amazon CloudFront Documentación Amazon CloudFront Guía para desarrolladores Registros estándar (registros de acceso) Puede configurar CloudFront para crear archivos de registro que contengan información detallada sobre cada solicitud de usuario (espectador) que CloudFront recibe. Estos se denominan registros estándar , también conocidos como registros de acceso . Cada registro contiene distintos datos, como el momento en que se recibió la solicitud, el tiempo de procesamiento, las rutas de solicitud y las respuestas del servidor. Puede utilizar estos registros de acceso para analizar los tiempos de respuesta y solucionar problemas. En el siguiente diagrama se muestra cómo CloudFront registra información sobre solicitudes para los objetos. En este ejemplo, las distribuciones están configuradas para enviar registros de acceso a un bucket de Amazon S3. En este ejemplo se muestran dos sitios web, A y B, y sus distribuciones de CloudFront correspondientes. Los usuarios solicitan sus objetos a través de URL asociadas a las distribuciones. CloudFront dirige cada solicitud a la ubicación de borde adecuada. CloudFront escribe los datos de cada solicitud en un archivo de registro específico en esa distribución. En este ejemplo, la información acerca de las solicitudes relacionadas con la Distribución A se escriben en un archivo de registro para la Distribución A. La información acerca de las solicitudes relacionadas con la Distribución B se escriben en un archivo de registro para la Distribución B. CloudFront periódicamente guarda el archivo de registro de la distribución en el bucket de Amazon S3 especificado al habilitar el registro. A continuación, CloudFront comienza a guardar información acerca de las solicitudes posteriores en un nuevo archivo de registro para la distribución. Si los espectadores no obtienen acceso a su contenido durante una hora determinada, no se reciben archivos de registro de esa hora. nota Recomendamos utilizar los registros de acceso para comprender la naturaleza de las solicitudes hechas a su contenido y no como una relación exhaustiva de todas las solicitudes. CloudFront envía registros de acceso en la medida en que sea posible. La entrada de registro de una solicitud determinada puede entregarse mucho después de la solicitud se haya procesado realmente y, en casos contados, es probable que una entrada de registro no se entregue en absoluto. Cuando se omite una entrada de registro de los registros de acceso, la cantidad de entradas de los registros de acceso no coincide con el uso que aparece en los informes de facturación y de uso de AWS. CloudFront admite dos versiones del registro estándar. El registro estándar (heredado) permite enviar los registros de acceso únicamente a Amazon S3. El registro estándar (v2) admite destinos de entrega adicionales. Puede configurar ambas opciones de registro o cualquiera de ellas en su distribución. Para obtener más información, consulte los temas siguientes: Temas Configuración del registro estándar (v2) Configuración del registro estándar (heredado) Referencia de registro estándar sugerencia CloudFront también ofrece registros en tiempo real, que le proporcionan información sobre las solicitudes realizadas a una distribución en tiempo real (los registros se envían en cuestión de segundos después de recibir las solicitudes). Puede usar registros en tiempo real para monitorear, analizar y tomar medidas en función del rendimiento de entrega de contenido.

En cas de conflit entre le contenu d'une traduction et celui de la version originale en anglais, la version anglaise prévaudra. Journaux d'accès (journaux standard) Vous pouvez configurer CloudFront pour créer des fichiers journaux contenant des informations détaillées sur chaque demande d'utilisateur (spectateur) CloudFront reçue. Ils sont appelés journaux d'accès , également appelés journaux standard . Chaque journal contient des informations comme l’heure à laquelle la demande a été reçue, l’heure du traitement, les chemins de demande et les réponses du serveur. Vous pouvez utiliser ces journaux d’accès pour analyser les modèles de trafic et résoudre des problèmes. Le schéma suivant montre comment CloudFront enregistre les informations relatives aux demandes relatives à vos objets. Dans cet exemple, les distributions sont configurées pour envoyer les journaux d’accès vers un compartiment Amazon S3. Dans cet exemple, vous avez deux sites Web, A et B, et deux CloudFront distributions correspondantes. Les utilisateurs demandent vos objets URLs en utilisant ceux associés à vos distributions.

https://docs.aws.amazon.com/it_it/AmazonCloudFront/latest/DeveloperGuide/AccessLogs.html | Registri di accesso (registri standard) - Amazon CloudFront Registri di accesso (registri standard) - Amazon CloudFront Documentazione Amazon CloudFront Guida per gli sviluppatori Le traduzioni sono generate tramite traduzione automatica. In caso di conflitto tra il contenuto di una traduzione e la versione originale in Inglese, quest'ultima prevarrà. Registri di accesso (registri standard) È possibile CloudFront configurare la creazione di file di registro che contengono informazioni dettagliate su ogni richiesta dell'utente (visualizzatore) che CloudFront riceve. Questi sono chiamati registri di accesso , noti anche come registri standard . Ogni log contiene informazioni come l’ora in cui è stata ricevuta la richiesta, il tempo di elaborazione, i percorsi delle richieste e le risposte del server. Puoi usare questi log di accesso per analizzare i tempi di risposta e risolvere i problemi. Il diagramma seguente mostra come CloudFront registra le informazioni sulle richieste relative agli oggetti. In questo esempio, le distribuzioni sono configurate per inviare i log di accesso a un bucket Amazon S3. In questo esempio, avete due siti Web, A e B, e due distribuzioni corrispondenti CloudFront. Gli utenti richiedono i vostri oggetti utilizzando URLs quelli associati alle vostre distribuzioni. CloudFront indirizza ogni richiesta verso la edge location appropriata. CloudFront scrive i dati su ogni richiesta in un file di registro specifico per quella distribuzione. In questo esempio, le informazioni sulle richieste relative alla distribuzione A sono registrate in un file di log per la distribuzione A. Le informazioni sulle richieste relative alla distribuzione B sono registrate in un file di log per la distribuzione B. CloudFront salva periodicamente il file di registro per una distribuzione nel bucket Amazon S3 che hai specificato quando hai abilitato la registrazione. CloudFront inizia quindi a salvare le informazioni sulle richieste successive in un nuovo file di registro per la distribuzione. Se i visualizzatori non accedono al contenuto durante una determinata ora, non riceverai alcun file di log per tale ora. Nota Ti consigliamo di utilizzare i log per comprendere la natura delle richieste relative ai tuoi contenuti, non come contabilità completa di tutte le richieste. CloudFront fornisce i log di accesso con la massima diligenza possibile. È possibile che la voce di log per una specifica richiesta venga distribuita molto tempo dopo l'elaborazione effettiva della richiesta e, in rari casi, che non venga distribuita affatto. Quando una voce di registro viene omessa dai registri di accesso, il numero di voci nei log di accesso non corrisponde all'utilizzo visualizzato nei report di utilizzo e fatturazione di AWS . CloudFront supporta due versioni di registrazione standard. La registrazione di log standard (legacy) supporta l’invio dei log di accesso solo ad Amazon S3. La registrazione di log standard (v2) supporta destinazioni di consegna aggiuntive. Puoi configurare entrambe le opzioni di registrazione di log o solo una delle due per la distribuzione. Per ulteriori informazioni, consulta i seguenti argomenti: Argomenti Configurazione della registrazione di log standard (v2) Configurazione della registrazione di log standard (legacy) Riferimento alla registrazione di log standard Suggerimento CloudFront offre anche registri di accesso in tempo reale, che forniscono informazioni sulle richieste effettuate a una distribuzione in tempo reale (i log vengono consegnati entro pochi secondi dalla ricezione delle richieste). È possibile utilizzare i log di accesso in tempo reale per monitorare, analizzare e intraprendere azioni in base alle prestazioni di distribuzione dei contenuti. Per ulteriori informazioni, consulta Utilizza i log di accesso in tempo reale . JavaScript è disabilitato o non è disponibile nel tuo browser. Per usare la documentazione AWS, JavaScript deve essere abilitato. Consulta le pagine della guida del browser per le istruzioni.

Our channel on discord https://discord.gg/7FpDnQ Notes: PHPJasper Can be used regardless of your PHP Framework For PHP versions less than 7.0 see: v1.16 Here are several examples of how to use PHPJasper Why PHPJasper? Did you ever had to create a good looking Invoice with a lot of fields for your great web app? I had to, and the solutions out there were not perfect. Generating HTML + CSS to make a PDF ? That doesn't make any sense! :) Then I found JasperReports the best open source solution for reporting. What can I do with this? Well, everything. JasperReports is a powerful tool for reporting and BI . From their website: The JasperReports Library is the world's most popular open source reporting engine. It is entirely written in Java and it is able to use data coming from any kind of data source and produce pixel-perfect documents that can be viewed, printed or exported in a variety of document formats including HTML, PDF, Excel, OpenOffice and Word. It is recommended using Jaspersoft Studio to build your reports, connect it to your datasource (ex: MySQL, POSTGRES), loop thru the results and output it to PDF, XLS, DOC, RTF, ODF, etc. Some examples of what you can do: Invoices Reports Listings Requirements PHP 7.2 or above Java JDK 1.8 Optional Any jdbc drivers to generate reports from a database (MySQL, PostgreSQL, MSSQL...), must be copied to a folder bin/jasperstarter/jdbc We ship the PostgreSQL (42.2.9) in the bin/jasperstarter/jdbc directory. We ship the MySQL connector (v5.1.48) in the bin/jasperstarter/jdbc directory. Microsoft JDBC Drivers SQL Server . Jaspersoft Studio (to draw your reports). Installation Install Composer if you don't have it. composer require geekcom/phpjasper Or in your file'composer.json' add: { "require" : { "geekcom/phpjasper" : " ^3.4.0 " } } And the just run: composer install and thats it. PHPJasper with Docker With Docker CE and docker-compose installed just run: docker-compose up -d docker exec -it phpjasper composer install To execute tests: docker exec -it phpjasper sudo composer test or docker exec -it phpjasper sudo composer testdox To see coverage manually of tests, execute the file: tests/log/report/index.html Help us writing new tests, make a fork :) Examples The Hello World example. Go to the examples directory in the root of the repository ( vendor/geekcom/phpjasper/examples ). Open the hello_world.jrxml file with Jaspersoft Studio or with your favorite text editor and take a look at the source code. Compiling First we need to compile our JRXML file into a JASPER binary file. We just have to do this one time. Note 1: You don't need to do this step if you are using Jaspersoft Studio . You can compile directly within the program. require __DIR__ . ' /vendor/autoload.php ' ; use PHPJasper \ PHPJasper ; $ input = __DIR__ . ' /vendor/geekcom/phpjasper/examples/hello_world.jrxml ' ; $ jasper = new PHPJasper ; $ jasper -> compile ( $ input )-> execute (); This commando will compile the hello_world.jrxml source file to a hello_world.jasper file. Processing Now lets process the report that we compile before: require __DIR__ . ' /vendor/autoload.php ' ; use PHPJasper \ PHPJasper ; $ input = __DIR__ . ' /vendor/geekcom/phpjasper/examples/hello_world.jasper ' ; $ output = __DIR__ . ' /vendor/geekcom/phpjasper/examples ' ; $ options = [ ' format ' => [ ' pdf ' , ' rtf ' ] ]; $ jasper = new PHPJasper ; $ jasper -> process ( $ input , $ output , $ options )-> execute (); Now check the examples folder! :) Great right? You now have 2 files, hello_world.pdf and hello_world.rtf . Check the methods compile and process in src/JasperPHP.php for more details Listing Parameters Querying the jasper file to examine parameters available in the given jasper report file: require __DIR__ . ' /vendor/autoload.php ' ; use PHPJasper \ PHPJasper ; $ input = __DIR__ . ' /vendor/geekcom/phpjasper/examples/hello_world_params.jrxml ' ; $ jasper = new PHPJasper ; $ output = $ jasper -> listParameters ( $ input )-> execute (); foreach ( $ output as $ parameter_description ) print $ parameter_description . ' <pre> ' ; Using database to generate reports We can also specify parameters for connecting to database: require __DIR__ . ' /vendor/autoload.php ' ; use PHPJasper \ PHPJasper ; $ input = ' /your_input_path/your_report.jasper ' ; $ output = ' /your_output_path ' ; $ options = [ ' format ' => [ ' pdf ' ], ' locale ' => ' en ' , ' params ' => [], ' db_connection ' => [ ' driver ' => ' postgres ' , //mysql, .... ' username ' => ' DB_USERNAME ' , ' password ' => ' DB_PASSWORD ' , ' host ' => ' DB_HOST ' , ' database ' => ' DB_DATABASE ' , ' port ' => ' 5432 ' ] ]; $ jasper = new PHPJasper ; $ jasper -> process ( $ input , $ output , $ options )-> execute (); Note 2: For a complete list of locales see Supported Locales Using MSSQL DataBase require __DIR__ . ' /vendor/autoload.php ' ; use PHPJasper \ PHPJasper ; $ input = ' /your_input_path/your_report.jasper or .jrxml ' ; $ output = ' /your_output_path ' ; $ jdbc_dir = __DIR__ . ' /vendor/geekcom/phpjasper/bin/jaspertarter/jdbc ' ; $ options = [ ' format ' => [ ' pdf ' ], ' locale ' => ' en ' , ' params ' => [], ' db_connection ' => [ ' driver ' => ' generic ' , ' host ' => ' 127.0.0.1 ' , ' port ' => ' 1433 ' , ' database ' => ' DataBaseName ' , ' username ' => ' UserName ' , ' password ' => ' password ' , ' jdbc_driver ' => ' com.microsoft.sqlserver.jdbc.SQLServerDriver ' , ' jdbc_url ' => ' jdbc:sqlserver://127.0.0.1:1433;databaseName=Teste ' , ' jdbc_dir ' => $ jdbc_dir ] ]; $ jasper = new PHPJasper ; $ jasper -> process ( $ input , $ output , $ options )-> execute (); Reports from a XML require __DIR__ . ' /vendor/autoload.php ' ; use PHPJasper \ PHPJasper ; $ input = ' /your_input_path/your_report.jasper ' ; $ output = ' /your_output_path ' ; $ data_file = __DIR__ . ' /your_data_files_path/your_xml_file.xml ' ; $ options = [ ' format ' => [ ' pdf ' ], ' params ' => [], ' locale ' => ' en ' , ' db_connection ' => [ ' driver ' => ' xml ' , ' data_file ' => $ data_file , ' xml_xpath ' => ' /your_xml_xpath ' ] ]; $ jasper = new PHPJasper ; $ jasper -> process ( $ input , $ output , $ options )-> execute (); Reports from a JSON require __DIR__ . ' /vendor/autoload.php ' ; use PHPJasper \ PHPJasper ; $ input = ' /your_input_path/your_report.jasper ' ; $ output = ' /your_output_path ' ; $ data_file = __DIR__ . ' /your_data_files_path/your_json_file.json ' ; $ options = [ ' format ' => [ ' pdf ' ], ' params ' => [], ' locale ' => ' en ' , ' db_connection ' => [ ' driver ' => ' json ' , ' data_file ' => $ data_file , ' json_query ' => ' your_json_query ' ] ]; $ jasper = new PHPJasper ; $ jasper -> process ( $ input , $ output , $ options )-> execute (); Performance Depends on the complexity, amount of data and the resources of your machine (let me know your use case). I have a report that generates a Invoice with a DB connection, images and multiple pages and it takes about 3/4 seconds to process. I suggest that you use a worker to generate the reports in the background. Thanks Cenote GmbH for the JasperStarter tool. JetBrains for the PhpStorm and all great tools. Questions?

http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/lambda-edge-delete-replicas.html | Delete Lambda@Edge functions and replicas - Amazon CloudFront Delete Lambda@Edge functions and replicas - Amazon CloudFront Documentation Amazon CloudFront Developer Guide Delete Lambda@Edge functions and replicas You can delete a Lambda@Edge function only when the replicas of the function have been deleted by CloudFront. Replicas of a Lambda function are automatically deleted in the following situations: After you remove the last association for the function from all of your CloudFront distributions. If more than one distribution uses a function, the replicas are deleted only after you remove the function association from the last distribution. After you delete the last distribution that a function was associated with. Replicas are typically deleted within a few hours. You cannot manually delete Lambda@Edge function replicas. This helps prevent a situation where a replica is deleted that is still in use, which would result in an error. Warning Don't build applications that use Lambda@Edge function replicas outside of CloudFront. These replicas are deleted when their associations with distributions are removed, or when distributions themselves are deleted. The replica that an outside application depends on might be removed without warning, causing it to fail. To delete a Lambda@Edge function association from a CloudFront distribution Sign in to the AWS Management Console and open the CloudFront console at https://console.aws.amazon.com/cloudfront/v4/home . Choose the ID of the distribution with the Lambda@Edge function association that you want to delete. Choose the Behaviors tab. Select the cache behavior that has the Lambda@Edge function association that you want to delete, and then choose Edit . Under Function associations , Function type , choose No association to delete the Lambda@Edge function association. Choose Save changes . After you delete a Lambda@Edge function association from a CloudFront distribution, you can optionally delete the Lambda function or function version from AWS Lambda. Wait a few hours after deleting the function association so that the Lambda@Edge function replicas can be cleaned up. After that, you can delete the function by using the Lambda console, AWS CLI, Lambda API, or an AWS SDK. You can also delete a specific version of a Lambda function if the version doesn't have any CloudFront distributions associated with it. After removing all the associations for a Lambda function version, wait a few hours. Then you can delete the function version. Javascript is disabled or is unavailable in your browser.

https://libc.llvm.org/build_and_test.html#building-with-bazel | Building and Testing the libc — The LLVM C Library Building and Testing the libc ¶ Build modes ¶ The libc can be built and tested in two different modes: The overlay mode - In this mode, one uses the static archive from LLVM’s libc along with the system libc. See Overlay Mode for more details on building and using the libc in this mode. You can only run the libc unittests in this mode. To run them, one simply does: $> ninja check-libc Note that, unittests for only those functions which are part of the overlay static archive will be run with the above command. The full build mode - In this mode, the libc is used as the only libc for the user’s application. See Full Host Build for more details on building and using the libc in this mode. Once configured for a full libc build, you can run three kinds of tests: Unit tests - You can run unittests by the command: $> ninja check-libc Integration tests - You can run integration tests by the command: $> ninja libc-integration-tests Building with VSCode ¶ As a quickstart to using VSCode for development, install the cmake extension and put the following in your settings.json file: { "cmake.sourceDirectory" : "${workspaceFolder}/runtimes" , "cmake.configureSettings" : { "LLVM_ENABLE_RUNTIMES" : [ "libc" , "compiler-rt" ], "LLVM_LIBC_FULL_BUILD" : true , "LLVM_ENABLE_SPHINX" : true , "LIBC_INCLUDE_DOCS" : true , "LLVM_LIBC_INCLUDE_SCUDO" : true , "COMPILER_RT_BUILD_SCUDO_STANDALONE_WITH_LLVM_LIBC" : true , "COMPILER_RT_BUILD_GWP_ASAN" : false , "COMPILER_RT_SCUDO_STANDALONE_BUILD_SHARED" : false , "CMAKE_EXPORT_COMPILE_COMMANDS" : true , "LIBC_CMAKE_VERBOSE_LOGGING" : true } } Building with Bazel ¶ To build with Bazel, use the following command: $> bazel build --config = generic_clang @llvm-project//libc/... To run the unit tests with bazel, use the following command: $> bazel test --config = generic_clang @llvm-project//libc/... The bazel target layout of libc is located at: utils/bazel/llvm-project-overlay/libc/BUILD.bazel . Building in a container for a different architecture ¶ Podman can be used together with QEMU to run container images built for architectures other than the host’s. This can be used to build and test the libc on other supported architectures for which you do not have access to hardware. It can also be used if the hardware is slower than emulation of its architecture on a more powerful machine under a different architecture. As an example, to build and test in a container for 32-bit Arm: To install the necessary packages on Arch Linux: $> pacman -S podman qemu-user-static qemu-user-static-binfmt \ qemu-system-arm To run Bash interactively in an Ubuntu 22.04 container for 32-bit Arm and bind-mount an existing checkout of llvm-project on the host: $> podman run -it \ -v </host/path/to/llvm-project>:</container/path/to/llvm-project> \ --arch arm docker.io/ubuntu:jammy bash Install necessary packages, invoke CMake, build, and run tests. libc Navigation Status & Support Implementation Status Architecture Support Platform Support Compiler Support Simple Usage Getting Started Advanced Usage Full Host Build Full Cross Build Overlay Mode libc for GPUs libc for UEFI Configure Options Hand-in-Hand Development LLVM-libc Maintainers Building and Testing the libc Developer Guides Bringup on a New OS or Architecture Contributing to the libc Project Useful Links Talks Source Code Bug Reports Discourse Join the Discord Discord Channel Buildbot Related Topics Documentation overview Previous: LLVM-libc Maintainers Next: Developer Guides Quick search ©2011-2026, LLVM Project. | Powered by Sphinx 7.2.6 & Alabaster 0.7.12 | Page source | 2026-01-13T09:30:36 |

This is done by treating the size of a void or of a function as 1. A consequence of this is that sizeof is also allowed on void and on function types, and returns 1. The option -Wpointer-arith requests a warning if these extensions are used. | 2026-01-13T09:30:36 |
https://gcc.gnu.org/onlinedocs/gcc/Variable-Length.html | Variable Length (Using the GNU Compiler Collection (GCC)) Next: Arrays of Length Zero , Up: Array, Union, and Struct Extensions [ Contents ][ Index ] 6.2.1 Arrays of Variable Length ¶ Variable-length automatic arrays are allowed in ISO C99, and as an extension GCC accepts them in C90 mode and in C++. These arrays are declared like any other automatic arrays, but with a length that is not a constant expression. The storage is allocated at the point of declaration and deallocated when the block scope containing the declaration exits. For example: FILE * concat_fopen (char *s1, char *s2, char *mode) { char str[strlen (s1) + strlen (s2) + 1]; strcpy (str, s1); strcat (str, s2); return fopen (str, mode); } Jumping or breaking out of the scope of the array name deallocates the storage. Jumping into the scope is not allowed; you get an error message for it. As an extension, GCC accepts variable-length arrays as a member of a structure or a union. For example: void foo (int n) { struct S { int x[n]; }; } You can use the function alloca to get an effect much like variable-length arrays. The function alloca is available in many other C implementations (but not in all). On the other hand, variable-length arrays are more elegant. There are other differences between these two methods. Space allocated with alloca exists until the containing function returns. The space for a variable-length array is deallocated as soon as the array name’s scope ends, unless you also use alloca in this scope. You can also use variable-length arrays as arguments to functions: struct entry tester (int len, char data[len][len]) { /* … */ } The length of an array is computed once when the storage is allocated and is remembered for the scope of the array in case you access it with sizeof . If you want to pass the array first and the length afterward, you can use a forward declaration in the parameter list—another GNU extension. struct entry tester (int len; char data[len][len], int len) { /* … */ } The ‘ int len ’ before the semicolon is a parameter forward declaration , and it serves the purpose of making the name len known when the declaration of data is parsed. Lists of parameter forward declarations are terminated by semicolons, and parameter forward declarations are separated within such lists by commas, just like in the regular list of parameter declarations. You can write any number of lists of parameter forward declaration, but using more than one is unnecessary. The last semicolon is followed by the list of parameter declarations. Each parameter forward declaration must match a parameter declaration in parameter name and data type. ISO C99 does not support parameter forward declarations.

The stack is not unwound before std::terminate is called. | 2026-01-13T09:30:36 |

Because the final length of the code produced by an asm statement is only known by the assembler, GCC must make an estimate as to how big it will be. It does this by counting the number of instructions in the pattern of the asm and multiplying that by the length of the longest instruction supported by that processor. (When working out the number of instructions, it assumes that any occurrence of a newline or of whatever statement separator character is supported by the assembler — typically ‘ ; ’ — indicates the end of an instruction.) Normally, GCC’s estimate is adequate to ensure that correct code is generated, but it is possible to confuse the compiler if you use pseudo instructions or assembler macros that expand into multiple real instructions, or if you use assembler directives that expand to more space in the object file than is needed for a single instruction. If this happens then the assembler may produce a diagnostic saying that a label is unreachable. This size is also used for inlining decisions. If you use asm inline instead of just asm , then for inlining purposes the size of the asm is taken as the minimum size, ignoring how many instructions GCC thinks it is. | 2026-01-13T09:30:36 |

Consider the following example: /* Use prototypes unless the compiler is old-fashioned. */ #ifdef __STDC__ #define P(x) x #else #define P(x) () #endif /* Prototype function declaration. */ int isroot P((uid_t)); /* Old-style function definition. */ int isroot (x) /* ??? lossage here ??? */ uid_t x; { return x == 0; } Suppose the type uid_t happens to be short . ISO C does not allow this example, because subword arguments in old-style non-prototype definitions are promoted. Therefore in this example the function definition’s argument is really an int , which does not match the prototype argument type of short . This restriction of ISO C makes it hard to write code that is portable to traditional C compilers, because the programmer does not know whether the uid_t type is short , int , or long . Therefore, in cases like these GNU C allows a prototype to override a later old-style definition. More precisely, in GNU C, a function prototype argument type overrides the argument type specified by a later old-style definition if the former type is the same as the latter type before promotion. Thus in GNU C the above example is equivalent to the following: int isroot (uid_t); int isroot (uid_t x) { return x == 0; } GNU C++ does not support old-style function definitions, so this extension is irrelevant.

https://gcc.gnu.org/onlinedocs/gcc/Basic-Asm.html#Qualifiers-1 | Basic Asm (Using the GNU Compiler Collection (GCC)) Next: Extended Asm - Assembler Instructions with C Expression Operands , Up: How to Use Inline Assembly Language in C Code [ Contents ][ Index ] 6.11.1 Basic Asm — Assembler Instructions Without Operands ¶ A basic asm statement has the following syntax: asm asm-qualifiers ( AssemblerInstructions ) For the C language, the asm keyword is a GNU extension. When writing C code that can be compiled with -ansi and the -std options that select C dialects without GNU extensions, use __asm__ instead of asm (see Alternate Keywords ). For the C++ language, asm is a standard keyword, but __asm__ can be used for code compiled with -fno-asm . Qualifiers ¶ volatile The optional volatile qualifier has no effect. All basic asm blocks are implicitly volatile. Basic asm statements outside of functions may not use any qualifiers. inline If you use the inline qualifier, then for inlining purposes the size of the asm statement is taken as the smallest size possible (see Size of an asm ). Parameters ¶ AssemblerInstructions This is a literal string that specifies the assembler code. In C++ with -std=gnu++11 or later, it can also be a constant expression inside parentheses (see C++11 Constant Expressions instead of String Literals ). The string can contain any instructions recognized by the assembler, including directives. GCC does not parse the assembler instructions themselves and does not know what they mean or even whether they are valid assembler input. You may place multiple assembler instructions together in a single asm string, separated by the characters normally used in assembly code for the system. A combination that works in most places is a newline to break the line, plus a tab character (written as ‘ \n\t ’). Some assemblers allow semicolons as a line separator. However, note that some assembler dialects use semicolons to start a comment. Remarks ¶ Using extended asm (see Extended Asm - Assembler Instructions with C Expression Operands ) typically produces smaller, safer, and more efficient code, and in most cases it is a better solution than basic asm . However, functions declared with the naked attribute require only basic asm (see Declaring Attributes of Functions ). Basic asm statements may be used both inside a C function or at file scope (“top-level”), where you can use this technique to emit assembler directives, define assembly language macros that can be invoked elsewhere in the file, or write entire functions in assembly language. Safely accessing C data and calling functions from basic asm is more complex than it may appear. To access C data, it is better to use extended asm . Do not expect a sequence of asm statements to remain perfectly consecutive after compilation. If certain instructions need to remain consecutive in the output, put them in a single multi-instruction asm statement. Note that GCC’s optimizers can move asm statements relative to other code, including across jumps. asm statements may not perform jumps into other asm statements. GCC does not know about these jumps, and therefore cannot take account of them when deciding how to optimize. Jumps from asm to C labels are only supported in extended asm . Under certain circumstances, GCC may duplicate (or remove duplicates of) your assembly code when optimizing. This can lead to unexpected duplicate symbol errors during compilation if your assembly code defines symbols or labels. Warning: The C standards do not specify semantics for asm , making it a potential source of incompatibilities between compilers. These incompatibilities may not produce compiler warnings/errors. GCC does not parse basic asm ’s AssemblerInstructions , which means there is no way to communicate to the compiler what is happening inside them. GCC has no visibility of symbols in the asm and may discard them as unreferenced. It also does not know about side effects of the assembler code, such as modifications to memory or registers. Unlike some compilers, GCC assumes that no changes to general purpose registers occur. This assumption may change in a future release. To avoid complications from future changes to the semantics and the compatibility issues between compilers, consider replacing basic asm with extended asm . See How to convert from basic asm to extended asm for information about how to perform this conversion. The compiler copies the assembler instructions in a basic asm verbatim to the assembly language output file, without processing dialects or any of the ‘ % ’ operators that are available with extended asm . This results in minor differences between basic asm strings and extended asm templates. For example, to refer to registers you might use ‘ %eax ’ in basic asm and ‘ %%eax ’ in extended asm . On targets such as x86 that support multiple assembler dialects, all basic asm blocks use the assembler dialect specified by the -masm command-line option (see x86 Options ). Basic asm provides no mechanism to provide different assembler strings for different dialects. For basic asm with non-empty assembler string GCC assumes the assembler block does not change any general purpose registers, but it may read or write any globally accessible variable. Here is an example of basic asm for i386: /* Note that this code will not compile with -masm=intel */ #define DebugBreak() asm("int $3") Next: Extended Asm - Assembler Instructions with C Expression Operands , Up: How to Use Inline Assembly Language in C Code [ Contents ][ Index ] | 2026-01-13T09:30:36 |

GNU C implements the POSIX XSI extension that additionally permits the use of va_arg with a pointer type to receive arguments of any other pointer type. In particular, in GNU C ‘ va_arg (ap, void *) ’ can safely be used to consume an argument of any pointer type. | 2026-01-13T09:30:36 |
https://gcc.gnu.org/onlinedocs/gcc/Compound-Literals.html | Compound Literals (Using the GNU Compiler Collection (GCC)) Next: Designated Initializers , Previous: Non-Constant Initializers , Up: Array, Union, and Struct Extensions [ Contents ][ Index ] 6.2.10 Compound Literals ¶ A compound literal looks like a cast of a brace-enclosed aggregate initializer list. Its value is an object of the type specified in the cast, containing the elements specified in the initializer. Unlike the result of a cast, a compound literal is an lvalue. ISO C99 and later support compound literals. As an extension, GCC supports compound literals also in C90 mode and in C++, although as explained below, the C++ semantics are somewhat different. Usually, the specified type of a compound literal is a structure. Assume that struct foo and structure are declared as shown: struct foo {int a; char b[2];} structure; Here is an example of constructing a struct foo with a compound literal: structure = ((struct foo) {x + y, 'a', 0}); This is equivalent to writing the following: { struct foo temp = {x + y, 'a', 0}; structure = temp; } You can also construct an array, though this is dangerous in C++, as explained below. If all the elements of the compound literal are (made up of) simple constant expressions suitable for use in initializers of objects of static storage duration, then the compound literal can be coerced to a pointer to its first element and used in such an initializer, as shown here: char **foo = (char *[]) { "x", "y", "z" }; As a GNU extension, GCC allows compound literals with a variable size. In this case, only empty initialization is allowed. int n = 4; char (*p)[n] = &(char[n]){ }; Compound literals for scalar types and union types are also allowed. In the following example the variable i is initialized to the value 2 , the result of incrementing the unnamed object created by the compound literal. int i = ++(int) { 1 }; As a GNU extension, GCC allows initialization of objects with static storage duration by compound literals (which is not possible in ISO C99 because the initializer is not a constant). It is handled as if the object were initialized only with the brace-enclosed list if the types of the compound literal and the object match. The elements of the compound literal must be constant. If the object being initialized has array type of unknown size, the size is determined by the size of the compound literal. static struct foo x = (struct foo) {1, 'a', 'b'}; static int y[] = (int []) {1, 2, 3}; static int z[] = (int [3]) {1}; The above lines are equivalent to the following: static struct foo x = {1, 'a', 'b'}; static int y[] = {1, 2, 3}; static int z[] = {1, 0, 0}; In C, a compound literal designates an unnamed object with static or automatic storage duration. In C++, a compound literal designates a temporary object that only lives until the end of its full-expression. As a result, well-defined C code that takes the address of a subobject of a compound literal can be undefined in C++, so G++ rejects the conversion of a temporary array to a pointer. For instance, if the array compound literal example above appeared inside a function, any subsequent use of foo in C++ would have undefined behavior because the lifetime of the array ends after the declaration of foo . As an optimization, G++ sometimes gives array compound literals longer lifetimes: when the array either appears outside a function or has a const -qualified type. If foo and its initializer had elements of type char *const rather than char * , or if foo were a global variable, the array would have static storage duration. But it is probably safest just to avoid the use of array compound literals in C++ code.

https://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html | Function Attributes (Using the GNU Compiler Collection (GCC)) Next: Specifying Attributes of Variables , Up: Attributes Specific to GCC [ Contents ][ Index ] 6.4.1 Declaring Attributes of Functions ¶ In GNU C and C++, you can use function attributes to specify certain function properties that may help the compiler optimize calls or check code more carefully for correctness. For example, you can use attributes to specify that a function never returns ( noreturn ), returns a value depending only on the values of its arguments ( const ), or has printf -style arguments ( format ). You can also use attributes to control memory placement, code generation options or call/return conventions within the function being annotated. Many of these attributes are target-specific. For example, many targets support attributes for defining interrupt handler functions, which typically must follow special register usage and return conventions. Such attributes are described in the subsection for each target. However, a considerable number of attributes are supported by most, if not all targets. Those are described in the Common Function Attributes section. GCC provides two different ways to specify attributes: the traditional GNU syntax using ‘ __attribute__ ((...)) ’ annotations, and the newer standard C and C++ syntax using ‘ [[...]] ’ with the ‘ gnu:: ’ prefix on attribute names. Note that the exact rules for placement of attributes in your source code are different depending on which syntax you use. See Attribute Syntax , for details. Compatible attribute specifications on distinct declarations of the same function are merged. An attribute specification that is not compatible with attributes already applied to a declaration of the same function is ignored with a warning. Some function attributes take one or more arguments that refer to the function’s parameters by their positions within the function parameter list. Such attribute arguments are referred to as positional arguments . Unless specified otherwise, positional arguments that specify properties of parameters with pointer types can also specify the same properties of the implicit C++ this argument in non-static member functions, and of parameters of reference to a pointer type. For ordinary functions, position one refers to the first parameter on the list. In C++ non-static member functions, position one refers to the implicit this pointer. The same restrictions and effects apply to function attributes used with ordinary functions or C++ member functions. GCC also supports attributes on variable declarations (see Specifying Attributes of Variables ), labels (see Label Attributes ), enumerators (see Enumerator Attributes ), statements (see Statement Attributes ), types (see Specifying Attributes of Types ), and on field declarations (for tainted_args ). There is some overlap between the purposes of attributes and pragmas (see Pragmas Accepted by GCC ). It has been found convenient to use __attribute__ to achieve a natural attachment of attributes to their corresponding declarations, whereas #pragma is of use for compatibility with other compilers or constructs that do not naturally form part of the grammar. In addition to the attributes documented here, GCC plugins may provide their own attributes.

https://libc.llvm.org/build_and_test.html#building-and-testing-the-libc | Building and Testing the libc — The LLVM C Library Building and Testing the libc ¶ Build modes ¶ The libc can be built and tested in two different modes: The overlay mode - In this mode, one uses the static archive from LLVM’s libc along with the system libc. See Overlay Mode for more details on building and using the libc in this mode. You can only run the libc unittests in this mode. To run them, one simply does: $> ninja check-libc Note that, unittests for only those functions which are part of the overlay static archive will be run with the above command. The full build mode - In this mode, the libc is used as the only libc for the user’s application. See Full Host Build for more details on building and using the libc in this mode. Once configured for a full libc build, you can run three kinds of tests: Unit tests - You can run unittests by the command: $> ninja check-libc Integration tests - You can run integration tests by the command: $> ninja libc-integration-tests Building with VSCode ¶ As a quickstart to using VSCode for development, install the cmake extension and put the following in your settings.json file: { "cmake.sourceDirectory" : "${workspaceFolder}/runtimes" , "cmake.configureSettings" : { "LLVM_ENABLE_RUNTIMES" : [ "libc" , "compiler-rt" ], "LLVM_LIBC_FULL_BUILD" : true , "LLVM_ENABLE_SPHINX" : true , "LIBC_INCLUDE_DOCS" : true , "LLVM_LIBC_INCLUDE_SCUDO" : true , "COMPILER_RT_BUILD_SCUDO_STANDALONE_WITH_LLVM_LIBC" : true , "COMPILER_RT_BUILD_GWP_ASAN" : false , "COMPILER_RT_SCUDO_STANDALONE_BUILD_SHARED" : false , "CMAKE_EXPORT_COMPILE_COMMANDS" : true , "LIBC_CMAKE_VERBOSE_LOGGING" : true } } Building with Bazel ¶ To build with Bazel, use the following command: $> bazel build --config = generic_clang @llvm-project//libc/... To run the unit tests with bazel, use the following command: $> bazel test --config = generic_clang @llvm-project//libc/... The bazel target layout of libc is located at: utils/bazel/llvm-project-overlay/libc/BUILD.bazel . Building in a container for a different architecture ¶ Podman can be used together with QEMU to run container images built for architectures other than the host’s. This can be used to build and test the libc on other supported architectures for which you do not have access to hardware. It can also be used if the hardware is slower than emulation of its architecture on a more powerful machine under a different architecture. As an example, to build and test in a container for 32-bit Arm: To install the necessary packages on Arch Linux: $> pacman -S podman qemu-user-static qemu-user-static-binfmt \ qemu-system-arm To run Bash interactively in an Ubuntu 22.04 container for 32-bit Arm and bind-mount an existing checkout of llvm-project on the host: $> podman run -it \ -v </host/path/to/llvm-project>:</container/path/to/llvm-project> \ --arch arm docker.io/ubuntu:jammy bash Install necessary packages, invoke CMake, build, and run tests. libc Navigation Status & Support Implementation Status Architecture Support Platform Support Compiler Support Simple Usage Getting Started Advanced Usage Full Host Build Full Cross Build Overlay Mode libc for GPUs libc for UEFI Configure Options Hand-in-Hand Development LLVM-libc Maintainers Building and Testing the libc Developer Guides Bringup on a New OS or Architecture Contributing to the libc Project Useful Links Talks Source Code Bug Reports Discourse Join the Discord Discord Channel Buildbot Related Topics Documentation overview Previous: LLVM-libc Maintainers Next: Developer Guides Quick search ©2011-2026, LLVM Project. | Powered by Sphinx 7.2.6 & Alabaster 0.7.12 | Page source | 2026-01-13T09:30:36 |
https://gcc.gnu.org/onlinedocs/gcc/Designated-Inits.html | Designated Inits (Using the GNU Compiler Collection (GCC)) Previous: Compound Literals , Up: Array, Union, and Struct Extensions [ Contents ][ Index ] 6.2.11 Designated Initializers ¶ Standard C90 requires the elements of an initializer to appear in a fixed order, the same as the order of the elements in the array or structure being initialized. In ISO C99 you can give the elements in any order, specifying the array indices or structure field names they apply to, and GNU C allows this as an extension in C90 mode as well. This extension is not implemented in GNU C++. To specify an array index, write ‘ [ index ] = ’ before the element value. For example, int a[6] = { [4] = 29, [2] = 15 }; is equivalent to int a[6] = { 0, 0, 15, 0, 29, 0 }; The index values must be constant expressions, even if the array being initialized is automatic. An alternative syntax for this that has been obsolete since GCC 2.5 but GCC still accepts is to write ‘ [ index ] ’ before the element value, with no ‘ = ’. To initialize a range of elements to the same value, write ‘ [ first ... last ] = value ’. This is a GNU extension. For example, int widths[] = { [0 ... 9] = 1, [10 ... 99] = 2, [100] = 3 }; If the value in it has side effects, the side effects happen only once, not for each initialized field by the range initializer. Note that the length of the array is the highest value specified plus one. In a structure initializer, specify the name of a field to initialize with ‘ . fieldname = ’ before the element value. For example, given the following structure, struct point { int x, y; }; the following initialization struct point p = { .y = yvalue, .x = xvalue }; is equivalent to struct point p = { xvalue, yvalue }; Another syntax that has the same meaning, obsolete since GCC 2.5, is ‘ fieldname : ’, as shown here: struct point p = { y: yvalue, x: xvalue }; Omitted fields are implicitly initialized the same as for objects that have static storage duration. The ‘ [ index ] ’ or ‘ . fieldname ’ is known as a designator . You can also use a designator (or the obsolete colon syntax) when initializing a union, to specify which element of the union should be used. For example, union foo { int i; double d; }; union foo f = { .d = 4 }; converts 4 to a double to store it in the union using the second element. By contrast, casting 4 to type union foo stores it into the union as the integer i , since it is an integer. See Cast to a Union Type . You can combine this technique of naming elements with ordinary C initialization of successive elements. Each initializer element that does not have a designator applies to the next consecutive element of the array or structure. For example, int a[6] = { [1] = v1, v2, [4] = v4 }; is equivalent to int a[6] = { 0, v1, v2, 0, v4, 0 }; Labeling the elements of an array initializer is especially useful when the indices are characters or belong to an enum type. For example: int whitespace[256] = { [' '] = 1, ['\t'] = 1, ['\h'] = 1, ['\f'] = 1, ['\n'] = 1, ['\r'] = 1 }; You can also write a series of ‘ . fieldname ’ and ‘ [ index ] ’ designators before an ‘ = ’ to specify a nested subobject to initialize; the list is taken relative to the subobject corresponding to the closest surrounding brace pair. For example, with the ‘ struct point ’ declaration above: struct point ptarray[10] = { [2].y = yv2, [2].x = xv2, [0].x = xv0 }; If the same field is initialized multiple times, or overlapping fields of a union are initialized, the value from the last initialization is used. When a field of a union is itself a structure, the entire structure from the last field initialized is used. If any previous initializer has side effect, it is unspecified whether the side effect happens or not. Currently, GCC discards the side-effecting initializer expressions and issues a warning.

https://libc.llvm.org/full_host_build.html#full-host-build | Full Host Build — The LLVM C Library Full Host Build ¶ Table of Contents Configure the build for development Build and test Configure the complete toolchain build Build and install Linux Headers Using your newly built libc Note Fullbuild requires running headergen, which is a python program that depends on pyyaml. The minimum versions are listed on the Generating Public and Internal headers page, as well as additional information. In this document, we will present a recipe to build the full libc for the host. When we say build the libc for the host , the goal is to build the libc for the same system on which the libc is being built. First, we will explain how to build for developing LLVM-libc, then we will explain how to build LLVM-libc as part of a complete toolchain. Configure the build for development ¶ Below is the list of commands for a simple recipe to build LLVM-libc for development. In this we’ve set the Ninja generator, set the build type to “Debug”, and enabled the Scudo allocator. This build also enables generating the documentation and verbose cmake logging, which are useful development features. Note if your build fails with an error saying the compiler can’t find <asm/unistd.h> or similar then you’re probably missing the symlink from /usr/include/asm to /usr/include/<HOST TRIPLE>/asm . Installing the gcc-multilib package creates this symlink, or you can do it manually with this command: sudo ln -s /usr/include/<HOST TRIPLE>/asm /usr/include/asm (your host triple will probably be similar to x86_64-linux-gnu ) $> cd llvm-project # The llvm-project checkout $> mkdir build $> cd build $> cmake ../runtimes \ -G Ninja \ -DCMAKE_C_COMPILER = clang \ -DCMAKE_CXX_COMPILER = clang++ \ -DLLVM_ENABLE_RUNTIMES = "libc;compiler-rt" \ -DLLVM_LIBC_FULL_BUILD = ON \ -DCMAKE_BUILD_TYPE = Debug \ -DLLVM_LIBC_INCLUDE_SCUDO = ON \ -DCOMPILER_RT_BUILD_SCUDO_STANDALONE_WITH_LLVM_LIBC = ON \ -DCOMPILER_RT_BUILD_GWP_ASAN = OFF \ -DCOMPILER_RT_SCUDO_STANDALONE_BUILD_SHARED = OFF \ -DCMAKE_EXPORT_COMPILE_COMMANDS = ON \ -DLLVM_ENABLE_SPHINX = ON -DLIBC_INCLUDE_DOCS = ON \ -DLIBC_CMAKE_VERBOSE_LOGGING = ON Build and test ¶ After configuring the build with the above cmake command, one can build test libc with the following command: $> ninja libc libm check-libc To build the docs run this command: $> ninja docs-libc-html To run a specific test, use the following: $> ninja libc.test.src.<HEADER>.<FUNCTION>_test.__unit__ $> ninja libc.test.src.ctype.isalpha_test.__unit__ # EXAMPLE Configure the complete toolchain build ¶ For a complete toolchain we recommend creating a sysroot (see the documentation of the --sysroot option here: https://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html ) which includes not only the components of LLVM’s libc, but also a full LLVM only toolchain consisting of the clang compiler, the lld linker and the compiler-rt runtime libraries. LLVM-libc is not quite complete enough to allow using and linking a C++ application against a C++ standard library (like libc++). Hence, we do not include libc++ in the sysroot. Note When the libc is complete enough, we should be able to include libc++ , libcxx-abi and libunwind in the LLVM only toolchain and use them to build and link C++ applications. Below is the cmake command for a bootstrapping build of LLVM. This will build clang and lld with the current system’s toolchain, then build compiler-rt and LLVM-libc with that freshly built clang. This ensures that LLVM-libc can take advantage of the latest clang features and optimizations. This build also uses Ninja as cmake’s generator, and sets lld and compiler-rt as the default for the fresh clang. Those settings are recommended, but the build should still work without them. The compiler-rt options are required for building Scudo as the allocator for LLVM-libc. Note if your build fails with an error saying the compiler can’t find <asm/unistd.h> or similar then you’re probably missing the symlink from /usr/include/asm to /usr/include/<TARGET TRIPLE>/asm . Installing the gcc-multilib package creates this symlink, or you can do it manually with this command: sudo ln -s /usr/include/<TARGET TRIPLE>/asm /usr/include/asm $> cd llvm-project # The llvm-project checkout $> mkdir build $> cd build $> SYSROOT = /path/to/sysroot # Remember to set this! $> cmake ../llvm \ -G Ninja \ -DLLVM_ENABLE_PROJECTS = "clang;lld" \ -DLLVM_ENABLE_RUNTIMES = "libc;compiler-rt" \ -DCMAKE_BUILD_TYPE = Release \ -DCMAKE_C_COMPILER = clang \ -DCMAKE_CXX_COMPILER = clang++ \ -DLLVM_LIBC_FULL_BUILD = ON \ -DLLVM_LIBC_INCLUDE_SCUDO = ON \ -DCOMPILER_RT_BUILD_SCUDO_STANDALONE_WITH_LLVM_LIBC = ON \ -DCOMPILER_RT_BUILD_GWP_ASAN = OFF \ -DCOMPILER_RT_SCUDO_STANDALONE_BUILD_SHARED = OFF \ -DCLANG_DEFAULT_LINKER = lld \ -DCLANG_DEFAULT_RTLIB = compiler-rt \ -DCMAKE_INSTALL_PREFIX = $SYSROOT Build and install ¶ Warning Running these install commands without setting a $SYSROOT will install them into your system include path, which may break your system. If you’re just trying to develop libc, then just run ninja check-libc to build the libc and run the tests. If you’ve already accidentally installed the headers, you may need to delete them from /usr/local/include . After configuring the build with the above cmake command, one can build and install the toolchain with $> ninja install-clang install-builtins install-compiler-rt \ install-core-resource-headers install-libc install-lld or $> ninja install Once the above command completes successfully, the $SYSROOT directory you have specified with the CMake configure step above will contain a full LLVM-only toolchain with which you can build practical/real-world C applications. See https://github.com/llvm/llvm-project/tree/main/libc/examples for examples of how to start using this new toolchain. Linux Headers ¶ If you are using the full libc on Linux, then you will also need to install Linux headers in your sysroot. Let’s build them from source. $> git clone --depth = 1 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git /tmp/linux $> make LLVM = 1 INSTALL_HDR_PATH = /path/to/sysroot -C /tmp/linux headers_install The headers can be built to target non-host architectures by adding the ARCH={arm|arm64|i386} to the above invocation of make . Using your newly built libc ¶ You can now use your newly built libc nearly like you would use any compiler invocation: $> /path/to/sysroot/bin/clang -static main.c Warning Because the libc does not yet support dynamic linking, the -static parameter must be added to all clang invocations. You can make sure you’re using the newly built toolchain by trying out features that aren’t yet supported by the system toolchain, such as fixed point. The following is an example program that demonstrates the difference: // $ $SYSROOT/bin/clang example.c -static -ffixed-point --sysroot=$SYSROOT #include <stdio.h> int main () { printf ( "Hello, World! \n %.9f \n %.9lK \n " , 4294967295.000000001 , 4294967295.000000001 ulK ); return 0 ; } libc Navigation Status & Support Implementation Status Architecture Support Platform Support Compiler Support Simple Usage Getting Started Advanced Usage Full Host Build Full Cross Build Overlay Mode libc for GPUs libc for UEFI Configure Options Hand-in-Hand Development LLVM-libc Maintainers Building and Testing the libc Developer Guides Bringup on a New OS or Architecture Contributing to the libc Project Useful Links Talks Source Code Bug Reports Discourse Join the Discord Discord Channel Buildbot Related Topics Documentation overview Previous: Getting Started Next: Full Cross Build Quick search ©2011-2026, LLVM Project. | Powered by Sphinx 7.2.6 & Alabaster 0.7.12 | Page source | 2026-01-13T09:30:36 |

https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/standard-logs-reference.html | Standard logging reference - Amazon CloudFront Standard logging reference - Amazon CloudFront Documentation Amazon CloudFront Developer Guide Timing of log file delivery How requests are logged when the request URL or headers exceed the maximum size Log file fields Analyze logs Standard logging reference The following sections apply to both standard logging (v2) and standard logging (legacy). Topics Timing of log file delivery How requests are logged when the request URL or headers exceed the maximum size Log file fields Analyze logs Timing of log file delivery CloudFront delivers logs for a distribution up to several times an hour. In general, a log file contains information about the requests that CloudFront received during a given time period. CloudFront usually delivers the log file for that time period to your destination within an hour of the events that appear in the log. Note, however, that some or all log file entries for a time period can sometimes be delayed by up to 24 hours. When log entries are delayed, CloudFront saves them in a log file for which the file name includes the date and time of the period in which the requests occurred , not the date and time when the file was delivered. When creating a log file, CloudFront consolidates information for your distribution from all of the edge locations that received requests for your objects during the time period that the log file covers. CloudFront can save more than one file for a time period depending on how many requests CloudFront receives for the objects associated with a distribution. CloudFront begins to reliably deliver access logs about four hours after you enable logging. You might get a few access logs before that time. Note If no users request your objects during the time period, you don't receive any log files for that period. How requests are logged when the request URL or headers exceed the maximum size If the total size of all request headers, including cookies, exceeds 20 KB, or if the URL exceeds 8192 bytes, CloudFront can't parse the request completely and can't log the request. Because the request isn't logged, you won't see in the log files the HTTP error status code returned. If the request body exceeds the maximum size, the request is logged, including the HTTP error status code. Log file fields The log file for a distribution contains 33 fields. The following list contains each field name, in order, along with a description of the information in that field. date The date on which the event occurred in the format YYYY-MM-DD . For example, 2019-06-30 . The date and time are in Coordinated Universal Time (UTC). For WebSocket connections, this is the date when the connection closed. time The time when the CloudFront server finished responding to the request (in UTC), for example, 01:42:39 . For WebSocket connections, this is the time when the connection is closed. x-edge-location The edge location that served the request. Each edge location is identified by a three-letter code and an arbitrarily assigned number (for example, DFW3). The three-letter code typically corresponds with the International Air Transport Association (IATA) airport code for an airport near the edge location's geographic location. (These abbreviations might change in the future.) sc-bytes The total number of bytes that the server sent to the viewer in response to the request, including headers. For WebSocket and gRPC connections, this is the total number of bytes sent from the server to the client through the connection. c-ip The IP address of the viewer that made the request, for example, 192.0.2.183 or 2001:0db8:85a3::8a2e:0370:7334 . If the viewer used an HTTP proxy or a load balancer to send the request, the value of this field is the IP address of the proxy or load balancer. See also the x-forwarded-for field. cs-method The HTTP request method received from the viewer. cs(Host) The domain name of the CloudFront distribution (for example, d111111abcdef8.cloudfront.net). cs-uri-stem The portion of the request URL that identifies the path and object (for example, /images/cat.jpg ). Question marks (?) in URLs and query strings are not included in the log. sc-status Contains one of the following values: The HTTP status code of the server's response (for example, 200 ). 000 , which indicates that the viewer closed the connection before the server could respond to the request. If the viewer closes the connection after the server starts to send the response, this field contains the HTTP status code of the response that the server started to send. cs(Referer) The value of the Referer header in the request. This is the name of the domain that originated the request. Common referrers include search engines, other websites that link directly to your objects, and your own website. cs(User-Agent) The value of the User-Agent header in the request. The User-Agent header identifies the source of the request, such as the type of device and browser that submitted the request or, if the request came from a search engine, which search engine. cs-uri-query The query string portion of the request URL, if any. When a URL doesn't contain a query string, this field's value is a hyphen (-). For more information, see Cache content based on query string parameters . cs(Cookie) The Cookie header in the request, including name—value pairs and the associated attributes. If you enable cookie logging, CloudFront logs the cookies in all requests regardless of which cookies you choose to forward to the origin. When a request doesn't include a cookie header, this field's value is a hyphen (-). For more information about cookies, see Cache content based on cookies . x-edge-result-type How the server classified the response after the last byte left the server. In some cases, the result type can change between the time that the server is ready to send the response and the time that it finishes sending the response. See also the x-edge-response-result-type field. For example, in HTTP streaming, suppose the server finds a segment of the stream in the cache. In that scenario, the value of this field would ordinarily be Hit . However, if the viewer closes the connection before the server has delivered the entire segment, the final result type (and the value of this field) is Error . WebSocket and gRPC connections will have a value of Miss for this field because the content is not cacheable and is proxied directly to the origin. Possible values include: Hit – The server served the object to the viewer from the cache. RefreshHit – The server found the object in the cache but the object had expired, so the server contacted the origin to verify that the cache had the latest version of the object. Miss – The request could not be satisfied by an object in the cache, so the server forwarded the request to the origin and returned the result to the viewer. LimitExceeded – The request was denied because a CloudFront quota (formerly referred to as a limit) was exceeded. CapacityExceeded – The server returned an HTTP 503 status code because it didn't have enough capacity at the time of the request to serve the object. Error – Typically, this means the request resulted in a client error (the value of the sc-status field is in the 4xx range) or a server error (the value of the sc-status field is in the 5xx range). If the value of the sc-status field is 200 , or if the value of this field is Error and the value of the x-edge-response-result-type field is not Error , it means the HTTP request was successful but the client disconnected before receiving all of the bytes. Redirect – The server redirected the viewer from HTTP to HTTPS according to the distribution settings. LambdaExecutionError – The Lambda@Edge function associated with the distribution didn't complete due to a malformed association, a function timeout, an AWS dependency issue, or another general availability problem. x-edge-request-id An opaque string that uniquely identifies a request. CloudFront also sends this string in the x-amz-cf-id response header. x-host-header The value that the viewer included in the Host header of the request. If you're using the CloudFront domain name in your object URLs (such as d111111abcdef8.cloudfront.net), this field contains that domain name. If you're using alternate domain names (CNAMEs) in your object URLs (such as www.example.com), this field contains the alternate domain name. If you're using alternate domain names, see cs(Host) in field 7 for the domain name that is associated with your distribution. cs-protocol The protocol of the viewer request ( http , https , grpcs , ws , or wss ). cs-bytes The total number of bytes of data that the viewer included in the request, including headers. For WebSocket and gRPC connections, this is the total number of bytes sent from the client to the server on the connection. time-taken The number of seconds (to the thousandth of a second, for example, 0.082) from when the server receives the viewer's request to when the server writes the last byte of the response to the output queue, as measured on the server. From the perspective of the viewer, the total time to get the full response will be longer than this value because of network latency and TCP buffering. x-forwarded-for If the viewer used an HTTP proxy or a load balancer to send the request, the value of the c-ip field is the IP address of the proxy or load balancer. In that case, this field is the IP address of the viewer that originated the request. This field can contain multiple comma-separated IP addresses. Each IP address can be an IPv4 address (for example, 192.0.2.183 ) or an IPv6 address (for example, 2001:0db8:85a3::8a2e:0370:7334 ). If the viewer did not use an HTTP proxy or a load balancer, the value of this field is a hyphen (-). ssl-protocol When the request used HTTPS, this field contains the SSL/TLS protocol that the viewer and server negotiated for transmitting the request and response. For a list of possible values, see the supported SSL/TLS protocols in Supported protocols and ciphers between viewers and CloudFront . When cs-protocol in field 17 is http , the value for this field is a hyphen (-). ssl-cipher When the request used HTTPS, this field contains the SSL/TLS cipher that the viewer and server negotiated for encrypting the request and response. For a list of possible values, see the supported SSL/TLS ciphers in Supported protocols and ciphers between viewers and CloudFront . When cs-protocol in field 17 is http , the value for this field is a hyphen (-). x-edge-response-result-type How the server classified the response just before returning the response to the viewer. See also the x-edge-result-type field. Possible values include: Hit – The server served the object to the viewer from the cache. RefreshHit – The server found the object in the cache but the object had expired, so the server contacted the origin to verify that the cache had the latest version of the object. Miss – The request could not be satisfied by an object in the cache, so the server forwarded the request to the origin server and returned the result to the viewer. LimitExceeded – The request was denied because a CloudFront quota (formerly referred to as a limit) was exceeded. CapacityExceeded – The server returned a 503 error because it didn't have enough capacity at the time of the request to serve the object. Error – Typically, this means the request resulted in a client error (the value of the sc-status field is in the 4xx range) or a server error (the value of the sc-status field is in the 5xx range). If the value of the x-edge-result-type field is Error and the value of this field is not Error , the client disconnected before finishing the download. Redirect – The server redirected the viewer from HTTP to HTTPS according to the distribution settings. LambdaExecutionError – The Lambda@Edge function associated with the distribution didn't complete due to a malformed association, a function timeout, an AWS dependency issue, or another general availability problem. cs-protocol-version The HTTP version that the viewer specified in the request. Possible values include HTTP/0.9 , HTTP/1.0 , HTTP/1.1 , HTTP/2.0 , and HTTP/3.0 . fle-status When field-level encryption is configured for a distribution, this field contains a code that indicates whether the request body was successfully processed. When the server successfully processes the request body, encrypts values in the specified fields, and forwards the request to the origin, the value of this field is Processed . The value of x-edge-result-type can still indicate a client-side or server-side error in this case. Possible values for this field include: ForwardedByContentType – The server forwarded the request to the origin without parsing or encryption because no content type was configured. ForwardedByQueryArgs – The server forwarded the request to the origin without parsing or encryption because the request contains a query argument that wasn't in the configuration for field-level encryption. ForwardedDueToNoProfile – The server forwarded the request to the origin without parsing or encryption because no profile was specified in the configuration for field-level encryption. MalformedContentTypeClientError – The server rejected the request and returned an HTTP 400 status code to the viewer because the value of the Content-Type header was in an invalid format. MalformedInputClientError – The server rejected the request and returned an HTTP 400 status code to the viewer because the request body was in an invalid format. MalformedQueryArgsClientError – The server rejected the request and returned an HTTP 400 status code to the viewer because a query argument was empty or in an invalid format. RejectedByContentType – The server rejected the request and returned an HTTP 400 status code to the viewer because no content type was specified in the configuration for field-level encryption. RejectedByQueryArgs – The server rejected the request and returned an HTTP 400 status code to the viewer because no query argument was specified in the configuration for field-level encryption. ServerError – The origin server returned an error. If the request exceeds a field-level encryption quota (formerly referred to as a limit), this field contains one of the following error codes, and the server returns HTTP status code 400 to the viewer. For a list of the current quotas on field-level encryption, see Quotas on field-level encryption . FieldLengthLimitClientError – A field that is configured to be encrypted exceeded the maximum length allowed. FieldNumberLimitClientError – A request that the distribution is configured to encrypt contains more than the number of fields allowed. RequestLengthLimitClientError – The length of the request body exceeded the maximum length allowed when field-level encryption is configured. If field-level encryption is not configured for the distribution, the value of this field is a hyphen (-). fle-encrypted-fields The number of field-level encryption fields that the server encrypted and forwarded to the origin. CloudFront servers stream the processed request to the origin as they encrypt data, so this field can have a value even if the value of fle-status is an error. If field-level encryption is not configured for the distribution, the value of this field is a hyphen (-). c-port The port number of the request from the viewer. time-to-first-byte The number of seconds between receiving the request and writing the first byte of the response, as measured on the server. x-edge-detailed-result-type This field contains the same value as the x-edge-result-type field, except in the following cases: When the object was served to the viewer from the Origin Shield layer, this field contains OriginShieldHit . When the object was not in the CloudFront cache and the response was generated by an origin request Lambda@Edge function , this field contains MissGeneratedResponse . When the value of the x-edge-result-type field is Error , this field contains one of the following values with more information about the error: AbortedOrigin – The server encountered an issue with the origin. ClientCommError – The response to the viewer was interrupted due to a communication problem between the server and the viewer. ClientGeoBlocked – The distribution is configured to refuse requests from the viewer's geographic location. ClientHungUpRequest – The viewer stopped prematurely while sending the request. Error – An error occurred for which the error type doesn't fit any of the other categories. This error type can occur when the server serves an error response from the cache. InvalidRequest – The server received an invalid request from the viewer. InvalidRequestBlocked – Access to the requested resource is blocked. InvalidRequestCertificate – The distribution doesn't match the SSL/TLS certificate for which the HTTPS connection was established. InvalidRequestHeader – The request contained an invalid header. InvalidRequestMethod – The distribution is not configured to handle the HTTP request method that was used. This can happen when the distribution supports only cacheable requests. OriginCommError – The request timed out while connecting to the origin, or reading data from the origin. OriginConnectError – The server couldn't connect to the origin. OriginContentRangeLengthError – The Content-Length header in the origin's response doesn't match the length in the Content-Range header. OriginDnsError – The server couldn't resolve the origin's domain name. OriginError – The origin returned an incorrect response. OriginHeaderTooBigError – A header returned by the origin is too big for the edge server to process. OriginInvalidResponseError – The origin returned an invalid response. OriginReadError – The server couldn't read from the origin. OriginWriteError – The server couldn't write to the origin. OriginZeroSizeObjectError – A zero size object sent from the origin resulted in an error.

As an extension, GNU C allows such arrays to be subscripted in C90 mode, though otherwise they do not decay to pointers outside C99 mode.

https://libc.llvm.org/build_and_test.html#building-in-a-container-for-a-different-architecture | Building and Testing the libc — The LLVM C Library Building and Testing the libc ¶ Build modes ¶ The libc can be built and tested in two different modes: The overlay mode - In this mode, one uses the static archive from LLVM’s libc along with the system libc. See Overlay Mode for more details on building and using the libc in this mode. You can only run the libc unittests in this mode. To run them, one simply does: $> ninja check-libc Note that, unittests for only those functions which are part of the overlay static archive will be run with the above command. The full build mode - In this mode, the libc is used as the only libc for the user’s application. See Full Host Build for more details on building and using the libc in this mode. Once configured for a full libc build, you can run three kinds of tests: Unit tests - You can run unittests by the command: $> ninja check-libc Integration tests - You can run integration tests by the command: $> ninja libc-integration-tests Building with VSCode ¶ As a quickstart to using VSCode for development, install the cmake extension and put the following in your settings.json file: { "cmake.sourceDirectory" : "${workspaceFolder}/runtimes" , "cmake.configureSettings" : { "LLVM_ENABLE_RUNTIMES" : [ "libc" , "compiler-rt" ], "LLVM_LIBC_FULL_BUILD" : true , "LLVM_ENABLE_SPHINX" : true , "LIBC_INCLUDE_DOCS" : true , "LLVM_LIBC_INCLUDE_SCUDO" : true , "COMPILER_RT_BUILD_SCUDO_STANDALONE_WITH_LLVM_LIBC" : true , "COMPILER_RT_BUILD_GWP_ASAN" : false , "COMPILER_RT_SCUDO_STANDALONE_BUILD_SHARED" : false , "CMAKE_EXPORT_COMPILE_COMMANDS" : true , "LIBC_CMAKE_VERBOSE_LOGGING" : true } } Building with Bazel ¶ To build with Bazel, use the following command: $> bazel build --config = generic_clang @llvm-project//libc/... To run the unit tests with bazel, use the following command: $> bazel test --config = generic_clang @llvm-project//libc/... The bazel target layout of libc is located at: utils/bazel/llvm-project-overlay/libc/BUILD.bazel . Building in a container for a different architecture ¶ Podman can be used together with QEMU to run container images built for architectures other than the host’s. This can be used to build and test the libc on other supported architectures for which you do not have access to hardware. It can also be used if the hardware is slower than emulation of its architecture on a more powerful machine under a different architecture. As an example, to build and test in a container for 32-bit Arm: To install the necessary packages on Arch Linux: $> pacman -S podman qemu-user-static qemu-user-static-binfmt \ qemu-system-arm To run Bash interactively in an Ubuntu 22.04 container for 32-bit Arm and bind-mount an existing checkout of llvm-project on the host: $> podman run -it \ -v </host/path/to/llvm-project>:</container/path/to/llvm-project> \ --arch arm docker.io/ubuntu:jammy bash Install necessary packages, invoke CMake, build, and run tests. libc Navigation Status & Support Implementation Status Architecture Support Platform Support Compiler Support Simple Usage Getting Started Advanced Usage Full Host Build Full Cross Build Overlay Mode libc for GPUs libc for UEFI Configure Options Hand-in-Hand Development LLVM-libc Maintainers Building and Testing the libc Developer Guides Bringup on a New OS or Architecture Contributing to the libc Project Useful Links Talks Source Code Bug Reports Discourse Join the Discord Discord Channel Buildbot Related Topics Documentation overview Previous: LLVM-libc Maintainers Next: Developer Guides Quick search ©2011-2026, LLVM Project. | Powered by Sphinx 7.2.6 & Alabaster 0.7.12 | Page source | 2026-01-13T09:30:36 |
https://gcc.gnu.org/onlinedocs/gcc/Basic-Asm.html#Parameters | Basic Asm (Using the GNU Compiler Collection (GCC)) Next: Extended Asm - Assembler Instructions with C Expression Operands , Up: How to Use Inline Assembly Language in C Code [ Contents ][ Index ] 6.11.1 Basic Asm — Assembler Instructions Without Operands ¶ A basic asm statement has the following syntax: asm asm-qualifiers ( AssemblerInstructions ) For the C language, the asm keyword is a GNU extension. When writing C code that can be compiled with -ansi and the -std options that select C dialects without GNU extensions, use __asm__ instead of asm (see Alternate Keywords ). For the C++ language, asm is a standard keyword, but __asm__ can be used for code compiled with -fno-asm . Qualifiers ¶ volatile The optional volatile qualifier has no effect. All basic asm blocks are implicitly volatile. Basic asm statements outside of functions may not use any qualifiers. inline If you use the inline qualifier, then for inlining purposes the size of the asm statement is taken as the smallest size possible (see Size of an asm ). Parameters ¶ AssemblerInstructions This is a literal string that specifies the assembler code. In C++ with -std=gnu++11 or later, it can also be a constant expression inside parentheses (see C++11 Constant Expressions instead of String Literals ). The string can contain any instructions recognized by the assembler, including directives. GCC does not parse the assembler instructions themselves and does not know what they mean or even whether they are valid assembler input. You may place multiple assembler instructions together in a single asm string, separated by the characters normally used in assembly code for the system. A combination that works in most places is a newline to break the line, plus a tab character (written as ‘ \n\t ’). Some assemblers allow semicolons as a line separator. However, note that some assembler dialects use semicolons to start a comment. Remarks ¶ Using extended asm (see Extended Asm - Assembler Instructions with C Expression Operands ) typically produces smaller, safer, and more efficient code, and in most cases it is a better solution than basic asm . However, functions declared with the naked attribute require only basic asm (see Declaring Attributes of Functions ). Basic asm statements may be used both inside a C function or at file scope (“top-level”), where you can use this technique to emit assembler directives, define assembly language macros that can be invoked elsewhere in the file, or write entire functions in assembly language. Safely accessing C data and calling functions from basic asm is more complex than it may appear. To access C data, it is better to use extended asm . Do not expect a sequence of asm statements to remain perfectly consecutive after compilation. If certain instructions need to remain consecutive in the output, put them in a single multi-instruction asm statement. Note that GCC’s optimizers can move asm statements relative to other code, including across jumps. asm statements may not perform jumps into other asm statements. GCC does not know about these jumps, and therefore cannot take account of them when deciding how to optimize. Jumps from asm to C labels are only supported in extended asm . Under certain circumstances, GCC may duplicate (or remove duplicates of) your assembly code when optimizing. This can lead to unexpected duplicate symbol errors during compilation if your assembly code defines symbols or labels. Warning: The C standards do not specify semantics for asm , making it a potential source of incompatibilities between compilers. These incompatibilities may not produce compiler warnings/errors. GCC does not parse basic asm ’s AssemblerInstructions , which means there is no way to communicate to the compiler what is happening inside them. GCC has no visibility of symbols in the asm and may discard them as unreferenced. It also does not know about side effects of the assembler code, such as modifications to memory or registers. Unlike some compilers, GCC assumes that no changes to general purpose registers occur. This assumption may change in a future release. To avoid complications from future changes to the semantics and the compatibility issues between compilers, consider replacing basic asm with extended asm . See How to convert from basic asm to extended asm for information about how to perform this conversion. The compiler copies the assembler instructions in a basic asm verbatim to the assembly language output file, without processing dialects or any of the ‘ % ’ operators that are available with extended asm . This results in minor differences between basic asm strings and extended asm templates. For example, to refer to registers you might use ‘ %eax ’ in basic asm and ‘ %%eax ’ in extended asm . On targets such as x86 that support multiple assembler dialects, all basic asm blocks use the assembler dialect specified by the -masm command-line option (see x86 Options ). Basic asm provides no mechanism to provide different assembler strings for different dialects. For basic asm with non-empty assembler string GCC assumes the assembler block does not change any general purpose registers, but it may read or write any globally accessible variable. Here is an example of basic asm for i386: /* Note that this code will not compile with -masm=intel */ #define DebugBreak() asm("int $3") Next: Extended Asm - Assembler Instructions with C Expression Operands , Up: How to Use Inline Assembly Language in C Code [ Contents ][ Index ] | 2026-01-13T09:30:36 |
https://gcc.gnu.org/onlinedocs/cpp/Implementation-defined-behavior.html#Implementation-defined-behavior | Implementation-defined behavior (The C Preprocessor) Next: Implementation limits , Up: Implementation Details [ Contents ][ Index ] 12.1 Implementation-defined behavior ¶ This is how CPP behaves in all the cases which the C standard describes as implementation-defined . This term means that the implementation is free to do what it likes, but must document its choice and stick to it. The mapping of physical source file multi-byte characters to the execution character set. The input character set can be specified using the -finput-charset option, while the execution character set may be controlled using the -fexec-charset and -fwide-exec-charset options. Identifier characters. The C and C++ standards allow identifiers to be composed of ‘ _ ’ and the alphanumeric characters. C++ also allows universal character names. C99 and later C standards permit both universal character names and implementation-defined characters. In both C and C++ modes, GCC accepts in identifiers exactly those extended characters that correspond to universal character names permitted by the chosen standard. GCC allows the ‘ $ ’ character in identifiers as an extension for most targets. This is true regardless of the std= switch, since this extension cannot conflict with standards-conforming programs. When preprocessing assembler, however, dollars are not identifier characters by default. Currently the targets that by default do not permit ‘ $ ’ are AVR, IP2K, MMIX, MIPS Irix 3, ARM aout, and PowerPC targets for the AIX operating system. You can override the default with -fdollars-in-identifiers or -fno-dollars-in-identifiers . See fdollars-in-identifiers . Non-empty sequences of whitespace characters. In textual output, each whitespace sequence is collapsed to a single space. For aesthetic reasons, the first token on each non-directive line of output is preceded with sufficient spaces that it appears in the same column as it did in the original source file. The numeric value of character constants in preprocessor expressions. The preprocessor and compiler interpret character constants in the same way; i.e. escape sequences such as ‘ \a ’ are given the values they would have on the target machine. The compiler evaluates a multi-character character constant a character at a time, shifting the previous value left by the number of bits per target character, and then or-ing in the bit-pattern of the new character truncated to the width of a target character. The final bit-pattern is given type int , and is therefore signed, regardless of whether single characters are signed or not. If there are more characters in the constant than would fit in the target int the compiler issues a warning, and the excess leading characters are ignored. For example, 'ab' for a target with an 8-bit char would be interpreted as ‘ (int) ((unsigned char) 'a' * 256 + (unsigned char) 'b') ’ , and '\234a' as ‘ (int) ((unsigned char) '\234' * 256 + (unsigned char) 'a') ’ . Source file inclusion. For a discussion on how the preprocessor locates header files, Include Operation . Interpretation of the filename resulting from a macro-expanded ‘ #include ’ directive. See Computed Includes . Treatment of a ‘ #pragma ’ directive that after macro-expansion results in a standard pragma. No macro expansion occurs on any ‘ #pragma ’ directive line, so the question does not arise. Note that GCC does not yet implement any of the standard pragmas.

https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html | Zero Length (Using the GNU Compiler Collection (GCC)) Next: Structures with No Members , Previous: Arrays of Variable Length , Up: Array, Union, and Struct Extensions [ Contents ][ Index ] 6.2.2 Arrays of Length Zero ¶ Declaring zero-length arrays is allowed in GNU C as an extension. A zero-length array can be useful as the last element of a structure that is really a header for a variable-length object: struct line { int length; char contents[0]; }; struct line *thisline = (struct line *) malloc (sizeof (struct line) + this_length); thisline->length = this_length; In this example, thisline->contents is an array of char that can hold up to thisline->length bytes. Although the size of a zero-length array is zero, an array member of this kind may increase the size of the enclosing type as a result of tail padding. The offset of a zero-length array member from the beginning of the enclosing structure is the same as the offset of an array with one or more elements of the same type. The alignment of a zero-length array is the same as the alignment of its elements. Declaring zero-length arrays in other contexts, including as interior members of structure objects or as non-member objects, is discouraged. Accessing elements of zero-length arrays declared in such contexts is undefined and may be diagnosed. In the absence of the zero-length array extension, in ISO C90 the contents array in the example above would typically be declared to have a single element. Unlike a zero-length array which only contributes to the size of the enclosing structure for the purposes of alignment, a one-element array always occupies at least as much space as a single object of the type. Although using one-element arrays this way is discouraged, GCC handles accesses to trailing one-element array members analogously to zero-length arrays. The preferred mechanism to declare variable-length types like struct line above is the ISO C99 flexible array member , with slightly different syntax and semantics: Flexible array members are written as contents[] without the 0 . Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero. Flexible array members may only appear as the last member of a struct that is otherwise non-empty. A structure containing a flexible array member, or a union containing such a structure (possibly recursively), may not be a member of a structure or an element of an array. (However, these uses are permitted by GCC as extensions, see details below.) The GCC extension accepts a structure containing an ISO C99 flexible array member , or a union containing such a structure (possibly recursively) to be a member of a structure. There are two situations: A structure containing a C99 flexible array member, or a union containing such a structure, is the last field of another structure, for example: struct flex { int length; char data[]; }; union union_flex { int others; struct flex f; }; struct out_flex_struct { int m; struct flex flex_data; }; struct out_flex_union { int n; union union_flex flex_data; }; In the above, both out_flex_struct.flex_data.data[] and out_flex_union.flex_data.f.data[] are considered as flexible arrays too. A structure containing a C99 flexible array member, or a union containing such a structure, is not the last field of another structure, for example: struct flex { int length; char data[]; }; struct mid_flex { int m; struct flex flex_data; int n; }; In the above, accessing a member of the array mid_flex.flex_data.data[] might have undefined behavior. Compilers do not handle such a case consistently. Any code relying on this case should be modified to ensure that flexible array members only end up at the ends of structures. Please use the warning option -Wflex-array-member-not-at-end to identify all such cases in the source code and modify them. This extension is now deprecated. Non-empty initialization of zero-length arrays is treated like any case where there are more initializer elements than the array holds, in that a suitable warning about “excess elements in array” is given, and the excess elements (all of them, in this case) are ignored. GCC allows static initialization of flexible array members. This is equivalent to defining a new structure containing the original structure followed by an array of sufficient size to contain the data. E.g. in the following, f1 is constructed as if it were declared like f2 . struct f1 { int x; int y[]; } f1 = { 1, { 2, 3, 4 } }; struct f2 { struct f1 f1; int data[3]; } f2 = { { 1 }, { 2, 3, 4 } }; The convenience of this extension is that f1 has the desired type, eliminating the need to consistently refer to f2.f1 . This has symmetry with normal static arrays, in that an array of unknown size is also written with [] . Of course, this extension only makes sense if the extra data comes at the end of a top-level object, as otherwise we would be overwriting data at subsequent offsets. To avoid undue complication and confusion with initialization of deeply nested arrays, we simply disallow any non-empty initialization except when the structure is the top-level object. For example: struct foo { int x; int y[]; }; struct bar { struct foo z; }; struct foo a = { 1, { 2, 3, 4 } }; // Valid. struct bar b = { { 1, { 2, 3, 4 } } }; // Invalid. struct bar c = { { 1, { } } }; // Valid. struct foo d[1] = { { 1, { 2, 3, 4 } } }; // Invalid.

https://gcc.gnu.org/onlinedocs/gcc/Compatibility.html | Compatibility (Using the GNU Compiler Collection (GCC)) Next: gcov —a Test Coverage Program , Previous: GNU Objective-C Features , Up: Introduction [ Contents ][ Index ] 10 Binary Compatibility ¶ Binary compatibility encompasses several related concepts: application binary interface (ABI) The set of runtime conventions followed by all of the tools that deal with binary representations of a program, including compilers, assemblers, linkers, and language runtime support. Some ABIs are formal with a written specification, possibly designed by multiple interested parties. Others are simply the way things are actually done by a particular set of tools. ABI conformance A compiler conforms to an ABI if it generates code that follows all of the specifications enumerated by that ABI. A library conforms to an ABI if it is implemented according to that ABI. An application conforms to an ABI if it is built using tools that conform to that ABI and does not contain source code that specifically changes behavior specified by the ABI. calling conventions Calling conventions are a subset of an ABI that specify of how arguments are passed and function results are returned. interoperability Different sets of tools are interoperable if they generate files that can be used in the same program. The set of tools includes compilers, assemblers, linkers, libraries, header files, startup files, and debuggers. Binaries produced by different sets of tools are not interoperable unless they implement the same ABI. This applies to different versions of the same tools as well as tools from different vendors. intercallability Whether a function in a binary built by one set of tools can call a function in a binary built by a different set of tools is a subset of interoperability. implementation-defined features Language standards include lists of implementation-defined features whose behavior can vary from one implementation to another. Some of these features are normally covered by a platform’s ABI and others are not. The features that are not covered by an ABI generally affect how a program behaves, but not intercallability. compatibility Conformance to the same ABI and the same behavior of implementation-defined features are both relevant for compatibility. The application binary interface implemented by a C or C++ compiler affects code generation and runtime support for: size and alignment of data types layout of structured types calling conventions register usage conventions interfaces for runtime arithmetic support object file formats In addition, the application binary interface implemented by a C++ compiler affects code generation and runtime support for: name mangling exception handling invoking constructors and destructors layout, alignment, and padding of classes layout and alignment of virtual tables Some GCC compilation options cause the compiler to generate code that does not conform to the platform’s default ABI. Other options cause different program behavior for implementation-defined features that are not covered by an ABI. These options are provided for consistency with other compilers that do not follow the platform’s default ABI or the usual behavior of implementation-defined features for the platform. Be very careful about using such options. Most platforms have a well-defined ABI that covers C code, but ABIs that cover C++ functionality are not yet common. Starting with GCC 3.2, GCC binary conventions for C++ are based on a written, vendor-neutral C++ ABI that was designed to be specific to 64-bit Itanium but also includes generic specifications that apply to any platform. This C++ ABI is also implemented by other compiler vendors on some platforms, notably GNU/Linux and BSD systems. We have tried hard to provide a stable ABI that will be compatible with future GCC releases, but it is possible that we will encounter problems that make this difficult. Such problems could include different interpretations of the C++ ABI by different vendors, bugs in the ABI, or bugs in the implementation of the ABI in different compilers. GCC’s -Wabi switch warns when G++ generates code that is probably not compatible with the C++ ABI. The C++ library used with a C++ compiler includes the Standard C++ Library, with functionality defined in the C++ Standard, plus language runtime support. The runtime support is included in a C++ ABI, but there is no formal ABI for the Standard C++ Library. Two implementations of that library are interoperable if one follows the de-facto ABI of the other and if they are both built with the same compiler, or with compilers that conform to the same ABI for C++ compiler and runtime support. When G++ and another C++ compiler conform to the same C++ ABI, but the implementations of the Standard C++ Library that they normally use do not follow the same ABI for the Standard C++ Library, object files built with those compilers can be used in the same program only if they use the same C++ library. This requires specifying the location of the C++ library header files when invoking the compiler whose usual library is not being used. The location of GCC’s C++ header files depends on how the GCC build was configured, but can be seen by using the G++ -v option. With default configuration options for G++ 3.3 the compile line for a different C++ compiler needs to include -I gcc_install_directory /include/c++/3.3 Similarly, compiling code with G++ that must use a C++ library other than the GNU C++ library requires specifying the location of the header files for that other library. The most straightforward way to link a program to use a particular C++ library is to use a C++ driver that specifies that C++ library by default. The g++ driver, for example, tells the linker where to find GCC’s C++ library ( libstdc++ ) plus the other libraries and startup files it needs, in the proper order. If a program must use a different C++ library and it’s not possible to do the final link using a C++ driver that uses that library by default, it is necessary to tell g++ the location and name of that library. It might also be necessary to specify different startup files and other runtime support libraries, and to suppress the use of GCC’s support libraries with one or more of the options -nostdlib , -nostartfiles , and -nodefaultlibs .

https://gcc.gnu.org/onlinedocs/gcc/Basic-Asm.html#Basic-Asm-----Assembler-Instructions-Without-Operands | Basic Asm (Using the GNU Compiler Collection (GCC)) Next: Extended Asm - Assembler Instructions with C Expression Operands , Up: How to Use Inline Assembly Language in C Code [ Contents ][ Index ] 6.11.1 Basic Asm — Assembler Instructions Without Operands ¶ A basic asm statement has the following syntax: asm asm-qualifiers ( AssemblerInstructions ) For the C language, the asm keyword is a GNU extension. When writing C code that can be compiled with -ansi and the -std options that select C dialects without GNU extensions, use __asm__ instead of asm (see Alternate Keywords ). For the C++ language, asm is a standard keyword, but __asm__ can be used for code compiled with -fno-asm . Qualifiers ¶ volatile The optional volatile qualifier has no effect. All basic asm blocks are implicitly volatile. Basic asm statements outside of functions may not use any qualifiers. inline If you use the inline qualifier, then for inlining purposes the size of the asm statement is taken as the smallest size possible (see Size of an asm ). Parameters ¶ AssemblerInstructions This is a literal string that specifies the assembler code. In C++ with -std=gnu++11 or later, it can also be a constant expression inside parentheses (see C++11 Constant Expressions instead of String Literals ). The string can contain any instructions recognized by the assembler, including directives. GCC does not parse the assembler instructions themselves and does not know what they mean or even whether they are valid assembler input. You may place multiple assembler instructions together in a single asm string, separated by the characters normally used in assembly code for the system. A combination that works in most places is a newline to break the line, plus a tab character (written as ‘ \n\t ’). Some assemblers allow semicolons as a line separator. However, note that some assembler dialects use semicolons to start a comment. Remarks ¶ Using extended asm (see Extended Asm - Assembler Instructions with C Expression Operands ) typically produces smaller, safer, and more efficient code, and in most cases it is a better solution than basic asm . However, functions declared with the naked attribute require only basic asm (see Declaring Attributes of Functions ). Basic asm statements may be used both inside a C function or at file scope (“top-level”), where you can use this technique to emit assembler directives, define assembly language macros that can be invoked elsewhere in the file, or write entire functions in assembly language. Safely accessing C data and calling functions from basic asm is more complex than it may appear. To access C data, it is better to use extended asm . Do not expect a sequence of asm statements to remain perfectly consecutive after compilation. If certain instructions need to remain consecutive in the output, put them in a single multi-instruction asm statement. Note that GCC’s optimizers can move asm statements relative to other code, including across jumps. asm statements may not perform jumps into other asm statements. GCC does not know about these jumps, and therefore cannot take account of them when deciding how to optimize. Jumps from asm to C labels are only supported in extended asm . Under certain circumstances, GCC may duplicate (or remove duplicates of) your assembly code when optimizing. This can lead to unexpected duplicate symbol errors during compilation if your assembly code defines symbols or labels. Warning: The C standards do not specify semantics for asm , making it a potential source of incompatibilities between compilers. These incompatibilities may not produce compiler warnings/errors. GCC does not parse basic asm ’s AssemblerInstructions , which means there is no way to communicate to the compiler what is happening inside them. GCC has no visibility of symbols in the asm and may discard them as unreferenced. It also does not know about side effects of the assembler code, such as modifications to memory or registers. Unlike some compilers, GCC assumes that no changes to general purpose registers occur. This assumption may change in a future release. To avoid complications from future changes to the semantics and the compatibility issues between compilers, consider replacing basic asm with extended asm . See How to convert from basic asm to extended asm for information about how to perform this conversion. The compiler copies the assembler instructions in a basic asm verbatim to the assembly language output file, without processing dialects or any of the ‘ % ’ operators that are available with extended asm . This results in minor differences between basic asm strings and extended asm templates. For example, to refer to registers you might use ‘ %eax ’ in basic asm and ‘ %%eax ’ in extended asm . On targets such as x86 that support multiple assembler dialects, all basic asm blocks use the assembler dialect specified by the -masm command-line option (see x86 Options ). Basic asm provides no mechanism to provide different assembler strings for different dialects. For basic asm with non-empty assembler string GCC assumes the assembler block does not change any general purpose registers, but it may read or write any globally accessible variable. Here is an example of basic asm for i386: /* Note that this code will not compile with -masm=intel */ #define DebugBreak() asm("int $3") Next: Extended Asm - Assembler Instructions with C Expression Operands , Up: How to Use Inline Assembly Language in C Code [ Contents ][ Index ] | 2026-01-13T09:30:36 |

https://libc.llvm.org/build_and_test.html#building-with-vscode | Building and Testing the libc — The LLVM C Library Building and Testing the libc ¶ Build modes ¶ The libc can be built and tested in two different modes: The overlay mode - In this mode, one uses the static archive from LLVM’s libc along with the system libc. See Overlay Mode for more details on building and using the libc in this mode. You can only run the libc unittests in this mode. To run them, one simply does: $> ninja check-libc Note that, unittests for only those functions which are part of the overlay static archive will be run with the above command. The full build mode - In this mode, the libc is used as the only libc for the user’s application. See Full Host Build for more details on building and using the libc in this mode. Once configured for a full libc build, you can run three kinds of tests: Unit tests - You can run unittests by the command: $> ninja check-libc Integration tests - You can run integration tests by the command: $> ninja libc-integration-tests Building with VSCode ¶ As a quickstart to using VSCode for development, install the cmake extension and put the following in your settings.json file: { "cmake.sourceDirectory" : "${workspaceFolder}/runtimes" , "cmake.configureSettings" : { "LLVM_ENABLE_RUNTIMES" : [ "libc" , "compiler-rt" ], "LLVM_LIBC_FULL_BUILD" : true , "LLVM_ENABLE_SPHINX" : true , "LIBC_INCLUDE_DOCS" : true , "LLVM_LIBC_INCLUDE_SCUDO" : true , "COMPILER_RT_BUILD_SCUDO_STANDALONE_WITH_LLVM_LIBC" : true , "COMPILER_RT_BUILD_GWP_ASAN" : false , "COMPILER_RT_SCUDO_STANDALONE_BUILD_SHARED" : false , "CMAKE_EXPORT_COMPILE_COMMANDS" : true , "LIBC_CMAKE_VERBOSE_LOGGING" : true } } Building with Bazel ¶ To build with Bazel, use the following command: $> bazel build --config = generic_clang @llvm-project//libc/... To run the unit tests with bazel, use the following command: $> bazel test --config = generic_clang @llvm-project//libc/... The bazel target layout of libc is located at: utils/bazel/llvm-project-overlay/libc/BUILD.bazel . Building in a container for a different architecture ¶ Podman can be used together with QEMU to run container images built for architectures other than the host’s. This can be used to build and test the libc on other supported architectures for which you do not have access to hardware. It can also be used if the hardware is slower than emulation of its architecture on a more powerful machine under a different architecture. As an example, to build and test in a container for 32-bit Arm: To install the necessary packages on Arch Linux: $> pacman -S podman qemu-user-static qemu-user-static-binfmt \ qemu-system-arm To run Bash interactively in an Ubuntu 22.04 container for 32-bit Arm and bind-mount an existing checkout of llvm-project on the host: $> podman run -it \ -v </host/path/to/llvm-project>:</container/path/to/llvm-project> \ --arch arm docker.io/ubuntu:jammy bash Install necessary packages, invoke CMake, build, and run tests. libc Navigation Status & Support Implementation Status Architecture Support Platform Support Compiler Support Simple Usage Getting Started Advanced Usage Full Host Build Full Cross Build Overlay Mode libc for GPUs libc for UEFI Configure Options Hand-in-Hand Development LLVM-libc Maintainers Building and Testing the libc Developer Guides Bringup on a New OS or Architecture Contributing to the libc Project Useful Links Talks Source Code Bug Reports Discourse Join the Discord Discord Channel Buildbot Related Topics Documentation overview Previous: LLVM-libc Maintainers Next: Developer Guides Quick search ©2011-2026, LLVM Project. | Powered by Sphinx 7.2.6 & Alabaster 0.7.12 | Page source | 2026-01-13T09:30:36 |

When writing C code that can be compiled with -ansi and the -std options that select C dialects without GNU extensions, use __asm__ instead of asm (see Alternate Keywords ). For the C++ language, asm is a standard keyword, but __asm__ can be used for code compiled with -fno-asm . Qualifiers ¶ volatile The optional volatile qualifier has no effect. All basic asm blocks are implicitly volatile. Basic asm statements outside of functions may not use any qualifiers. inline If you use the inline qualifier, then for inlining purposes the size of the asm statement is taken as the smallest size possible (see Size of an asm ). Parameters ¶ AssemblerInstructions This is a literal string that specifies the assembler code. In C++ with -std=gnu++11 or later, it can also be a constant expression inside parentheses (see C++11 Constant Expressions instead of String Literals ). The string can contain any instructions recognized by the assembler, including directives. GCC does not parse the assembler instructions themselves and does not know what they mean or even whether they are valid assembler input. You may place multiple assembler instructions together in a single asm string, separated by the characters normally used in assembly code for the system. A combination that works in most places is a newline to break the line, plus a tab character (written as ‘ \n\t ’). Some assemblers allow semicolons as a line separator. However, note that some assembler dialects use semicolons to start a comment. Remarks ¶ Using extended asm (see Extended Asm - Assembler Instructions with C Expression Operands ) typically produces smaller, safer, and more efficient code, and in most cases it is a better solution than basic asm .

It also gets rid of the runtime dependency on libdvbpsi thanks to biTStream. VideoLAN is also happy to introduce the first public release of biTStream , a set of C headers allowing a simpler access (read and write) to binary structures such as specified by MPEG, DVB, IETF, etc... It is released under the MIT license to avoid readability concerns being shadowed by license issues. It already has a pretty decent support of MPEG systems packet structures, MPEG PSI, DVB SI, DVB simulcast and IETF RTP. libaacs 0.3.0 2011-12-02 The doom9 researchers and the libaacs developers would like to present the first official release of their library of the implementation of the libaacs standard. libaacs 0.3.0 source code can be downloaded on the VideoLAN download service . Nota Bene: This library is of no use without AACS keys. libbluray 0.2.1 2011-11-30 VideoLAN and the libbluray developers would like to present the first official release of their library to help playback of Blu-Ray for open source systems. libbluray 0.2.1 source code can be downloaded on the VideoLAN ftp . VLC 1.1.12 2011-10-06 VideoLAN and the VLC development team present VLC 1.1.12, a bug and security fix release with improvements for audio output on Mac OS X and with PulseAudio.

Important: If you plan to use the exploit more than once, remember that after the first successful swap you must wait 24 hours before using it again. Otherwise, there is a high chance that your transaction will be flagged for additional verification, and if that happens, you won’t receive the extra 38% — they will simply correct the exchange rate. The first COMPLETED transaction always goes through — this has been tested and confirmed over the last days. Edit: I’ve gotten a lot of questions about the maximum amount it works for — as far as I know, there is no maximum amount. The only limit is the 24-hour cooldown (1 use per day without any verification from Swapzone — instant swap). /* Exploit verified and working as of 13 January 2026, Time 10:10:46 AM UTC /* Advertisement Public Pastes Untitled 8 min ago | 0.94 KB Untitled 18 min ago | 0.94 KB Untitled 29 min ago | 0.94 KB Untitled 39 min ago | 0.94 KB Untitled 49 min ago | 0.94 KB Untitled 59 min ago | 0.94 KB Untitled 1 hour ago | 10.19 KB Untitled 3 hours ago | 13.48 KB create new paste / syntax languages / archive / faq / tools / night mode / api / scraping api / news / pro privacy statement / cookies policy / terms of service / security disclosure / dmca / report abuse / contact By using Pastebin.com you agree to our cookies policy to enhance your experience.

http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/lambda-event-structure.html#lambda-event-structure-response-viewer | Lambda@Edge event structure - Amazon CloudFront Lambda@Edge event structure - Amazon CloudFront Documentation Amazon CloudFront Developer Guide Dynamic origin selection Request events Response events Lambda@Edge event structure The following topics describe the request and response event objects that CloudFront passes to a Lambda@Edge function when it's triggered. Topics Dynamic origin selection Request events Response events Dynamic origin selection You can use the path pattern in a cache behavior to route requests to an origin based on the path and name of the requested object, such as images/*.jpg . Using Lambda@Edge, you can also route requests to an origin based on other characteristics, such as the values in request headers. There are a number of ways that this dynamic origin selection can be useful. For example, you can distribute requests across origins in different geographic areas to help with global load balancing. Or you can selectively route requests to different origins that each serve a particular function: bot handling, SEO optimization, authentication, and so on. For code examples that demonstrate how to use this feature, see Content-based dynamic origin selection - examples . In the CloudFront origin request event, the origin object in the event structure contains information about the origin that the request would be routed to, based on the path pattern. You can update the values in the origin object to route a request to a different origin. When you update the origin object, you don't need to define the origin in the distribution. You can also replace an Amazon S3 origin object with a custom origin object, and vice versa. You can only specify a single origin per request, though; either a custom origin or an Amazon S3 origin, but not both. Request events The following topics show the structure of the object that CloudFront passes to a Lambda function for viewer and origin request events . These examples show a GET request with no body. Following the examples is a list of all the possible fields in viewer and origin request events. Topics Example viewer request Example origin request Request event fields Example viewer request The following example shows a viewer request event object. { "Records": [ { "cf": { "config": { "distributionDomainName": "d111111abcdef8.cloudfront.net", "distributionId": "EDFDVBD6EXAMPLE", "eventType": "viewer-request", "requestId": "4TyzHTaYWb1GX1qTfsHhEqV6HUDd_BzoBZnwfnvQc_1oF26ClkoUSEQ==" }, "request": { "clientIp": "203.0.113.178", "headers": { "host": [ { "key": "Host", "value": "d111111abcdef8.cloudfront.net" } ], "user-agent": [ { "key": "User-Agent", "value": "curl/7.66.0" } ], "accept": [ { "key": "accept", "value": "*/*" } ] }, "method": "GET", "querystring": "", "uri": "/" } } } ] } Example origin request The following example shows an origin request event object. { "Records": [ { "cf": { "config": { "distributionDomainName": "d111111abcdef8.cloudfront.net", "distributionId": "EDFDVBD6EXAMPLE", "eventType": "origin-request", "requestId": "4TyzHTaYWb1GX1qTfsHhEqV6HUDd_BzoBZnwfnvQc_1oF26ClkoUSEQ==" }, "request": { "clientIp": "203.0.113.178", "headers": { "x-forwarded-for": [ { "key": "X-Forwarded-For", "value": "203.0.113.178" } ], "user-agent": [ { "key": "User-Agent", "value": "Amazon CloudFront" } ], "via": [ { "key": "Via", "value": "2.0 2afae0d44e2540f472c0635ab62c232b.cloudfront.net (CloudFront)" } ], "host": [ { "key": "Host", "value": "example.org" } ], "cache-control": [ { "key": "Cache-Control", "value": "no-cache" } ] }, "method": "GET", "origin": { "custom": { "customHeaders": { }, "domainName": "example.org", "keepaliveTimeout": 5, "path": "", "port": 443, "protocol": "https", "readTimeout": 30, "responseCompletionTimeout": 30, "sslProtocols": [ "TLSv1", "TLSv1.1", "TLSv1.2" ] } }, "querystring": "", "uri": "/" } } } ] } Request event fields Request event object data is contained in two subobjects: config ( Records.cf.config ) and request ( Records.cf.request ). The following lists describe each subobject's fields. Fields in the config object The following list describes the fields in the config object ( Records.cf.config ). distributionDomainName (read-only) The domain name of the distribution that's associated with the request. distributionID (read-only) The ID of the distribution that's associated with the request. eventType (read-only) The type of trigger that's associated with the request: viewer-request or origin-request . requestId (read-only) An encrypted string that uniquely identifies a viewer-to-CloudFront request. The requestId value also appears in CloudFront access logs as x-edge-request-id . For more information, see Access logs (standard logs) and Log file fields . Fields in the request object The following list describes the fields in the request object ( Records.cf.request ). clientIp (read-only) The IP address of the viewer that made the request. If the viewer used an HTTP proxy or a load balancer to send the request, the value is the IP address of the proxy or load balancer. headers (read/write) The headers in the request. Note the following: The keys in the headers object are lowercase versions of standard HTTP header names. Using lowercase keys gives you case-insensitive access to the header values. Each header object (for example, headers["accept"] or headers["host"] ) is an array of key–value pairs. For a given header, the array contains one key–value pair for each value in the request. key contains the case-sensitive name of the header as it appeared in the HTTP request; for example, Host , User-Agent , X-Forwarded-For , Cookie , and so on. value contains the header value as it appeared in the HTTP request. When your Lambda function adds or modifies request headers and you don't include the header key field, Lambda@Edge automatically inserts a header key using the header name that you provide. Regardless of how you've formatted the header name, the header key that's inserted automatically is formatted with initial capitalization for each part, separated by hyphens (-). For example, you can add a header like the following, without a header key : "user-agent": [ { "value": "ExampleCustomUserAgent/1.X.0" } ] In this example, Lambda@Edge automatically inserts "key": "User-Agent" . For information about restrictions on header usage, see Restrictions on edge functions . method (read-only) The HTTP method of the request. querystring (read/write) The query string, if any, in the request. If the request doesn't include a query string, the event object still includes querystring with an empty value. For more information about query strings, see Cache content based on query string parameters . uri (read/write) The relative path of the requested object. If your Lambda function modifies the uri value, note the following: The new uri value must begin with a forward slash (/). When a function changes the uri value, that changes the object that the viewer is requesting. When a function changes the uri value, that doesn't change the cache behavior for the request or the origin that the request is sent to. body (read/write) The body of the HTTP request. The body structure can contain the following fields: inputTruncated (read-only) A Boolean flag that indicates whether the body was truncated by Lambda@Edge. For more information, see Restrictions on the request body with the include body option . action (read/write) The action that you intend to take with the body. The options for action are the following: read-only: This is the default. When returning the response from the Lambda function, if action is read-only, Lambda@Edge ignores any changes to encoding or data . replace: Specify this when you want to replace the body sent to the origin. encoding (read/write) The encoding for the body. When Lambda@Edge exposes the body to the Lambda function, it first converts the body to base64-encoding. If you choose replace for the action to replace the body, you can opt to use base64 (the default) or text encoding. If you specify encoding as base64 but the body is not valid base64, CloudFront returns an error. data (read/write) The request body content. origin (read/write) (origin events only) The origin to send the request to. The origin structure must contain exactly one origin , which can be a custom origin or an Amazon S3 origin. Depending on your origin type that you specify (custom or Amazon S3 origins), you must specify the following fields in your request: customHeaders (read/write) (custom and Amazon S3 origins) (Optional) You can include custom headers with the request by specifying a header name and value pair for each custom header. You can't add headers that are disallowed, and a header with the same name can't be present in Records.cf.request.headers . The notes about request headers also apply to custom headers. For more information, see Custom headers that CloudFront can’t add to origin requests and Restrictions on edge functions . domainName (read/write) (custom and Amazon S3 origins) The domain name of the origin. The domain name can't be empty. For custom origins – Specify a DNS domain name, such as www.example.com . The domain name can't include a colon (:), and can't be an IP address. The domain name can be up to 253 characters. For Amazon S3 origins – Specify the DNS domain name of the Amazon S3 bucket, such as amzn-s3-demo-bucket.s3.eu-west-1.amazonaws.com . The name can be up to 128 characters, and must be all lowercase. path (read/write) (custom and Amazon S3 origins) The directory path at the origin where the request should locate content. The path should start with a forward slash (/) but shouldn't end with one (for example, it shouldn't end with example-path/ ). For custom origins only, the path should be URL encoded and have a maximum length of 255 characters. keepaliveTimeout (read/write) (custom origins only) How long, in seconds, that CloudFront should try to maintain the connection to the origin after receiving the last packet of the response. The value must be a number from 1–120, inclusive. port (read/write) (custom origins only) The port that CloudFront should connect to at your custom origin. The port must be 80, 443, or a number in the range of 1024–65535, inclusive. protocol (read/write) (custom origins only) The connection protocol that CloudFront should use when connecting to your origin. The value can be http or https . readTimeout (read/write) (custom and Amazon S3 origins) How long, in seconds, CloudFront should wait for a response after sending a request to your origin. This also specifies how long CloudFront should wait after receiving a packet of a response before receiving the next packet. The value must be a number from 1–120, inclusive. If you need a higher quota, see Response timeout per origin . responseCompletionTimeout (read/write) (custom and Amazon S3 origins) The time (in seconds) that a request from CloudFront to the origin can stay open and wait for a response. If the complete response isn't received from the origin by this time, CloudFront ends the connection. The value for responseCompletionTimeout must be equal to or greater than the value for the readTimeout . If you set this value to 0, it removes any previous value you set and returns to the default. You can also accomplish this by deleting the responseCompletionTimeout field from the event request. sslProtocols (read/write) (custom origins only) The minimum SSL/TLS protocol that CloudFront can use when establishing an HTTPS connection with your origin. Values can be any of the following: TLSv1.2 , TLSv1.1 , TLSv1 , or SSLv3 . authMethod (read/write) (Amazon S3 origins only) If you're using an origin access identity (OAI) , set this field to origin-access-identity . If you aren't using an OAI, set it to none . If you set authMethod to origin-access-identity , there are several requirements: You must specify the region (see the following field). You must use the same OAI when you change the request from one Amazon S3 origin to another. You can't use an OAI when you change the request from a custom origin to an Amazon S3 origin. Note This field does not support origin access control (OAC) . region (read/write) (Amazon S3 origins only) The AWS Region of your Amazon S3 bucket. This is required only when you set authMethod to origin-access-identity .

For more information about the fields in the request object, see Fields in the request object . The following lists describe the fields in the config and response subobjects. Fields in the config object The following list describes the fields in the config object ( Records.cf.config ). distributionDomainName (read-only) The domain name of the distribution that's associated with the response. distributionID (read-only) The ID of the distribution that's associated with the response. eventType (read-only) The type of trigger that's associated with the response: origin-response or viewer-response . requestId (read-only) An encrypted string that uniquely identifies the viewer-to-CloudFront request that this response is associated with. The requestId value also appears in CloudFront access logs as x-edge-request-id . For more information, see Access logs (standard logs) and Log file fields . Fields in the response object The following list describes the fields in the response object ( Records.cf.response ). For information about using a Lambda@Edge function to generate an HTTP response, see Generate HTTP responses in request triggers . headers (read/write) The headers in the response. Note the following: The keys in the headers object are lowercase versions of standard HTTP header names. Using lowercase keys gives you case-insensitive access to the header values. Each header object (for example, headers["content-type"] or headers["content-length"] ) is an array of key–value pairs. For a given header, the array contains one key–value pair for each value in the response. key contains the case-sensitive name of the header as it appears in the HTTP response; for example, Content-Type , Content-Length , Cookie , and so on. value contains the header value as it appears in the HTTP response. When your Lambda function adds or modifies response headers and you don't include the header key field, Lambda@Edge automatically inserts a header key using the header name that you provide. Regardless of how you've formatted the header name, the header key that's inserted automatically is formatted with initial capitalization for each part, separated by hyphens (-). For example, you can add a header like the following, without a header key : "content-type": [ { "value": "text/html;charset=UTF-8" } ] In this example, Lambda@Edge automatically inserts "key": "Content-Type" . For information about restrictions on header usage, see Restrictions on edge functions . status The HTTP status code of the response. statusDescription The HTTP status description of the response.

For up-to-date documentation, see the latest version ( Next (Incubating) ). Operations TLS Version: 1.0.x On this page TLS Introduction TLS allows for the secure transmission of information across the network between a client and a server through the use of encryption. This prevents any unauthorized individuals from eavesdropping on your communications or accessing data that you send over the network. BifroMQ provides extensive support for SSL/TLS connectivity options, including TLS connections and WebSocket Security connections. It also supports flexible configuration options for both single and two-way authentication, allowing you to select different levels of authentication based on your configuration. Prerequisites You will need to prepare and configure the SSL/TLS certificates that you will use. In a testing environment, you can generate self-signed certificates using the OpenSSL tool. However, in a production environment, you should use certificates issued by a trusted CA (Certificate Authority). Enabling via Configuration Follow the instructions in the brokerSSLCtxConfig section of the Configuration File Manual . Enable the desired level of authentication, enter the appropriate certificate names, and place the certificate files in the location specified by the configuration parameters. Edit this page Previous Operations Next High Availability Introduction Prerequisites Enabling via Configuration Apache BifroMQ is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

It looks just like ordinary casts with the constraint that the type specified is a union type. You can specify the type either with the union keyword or with a typedef name that refers to a union. The result of a cast to a union is a temporary rvalue of the union type with a member whose type matches that of the operand initialized to the value of the operand. The effect of a cast to a union is similar to a compound literal except that it yields an rvalue like standard casts do. See Compound Literals . Expressions that may be cast to the union type are those whose type matches at least one of the members of the union. Thus, given the following union and variables: union foo { int i; double d; }; int x; double y; union foo z; both x and y can be cast to type union foo and the following assignments z = (union foo) x; z = (union foo) y; are shorthand equivalents of these z = (union foo) { .i = x }; z = (union foo) { .d = y }; However, (union foo) FLT_MAX; is not a valid cast because the union has no member of type float . Using the cast as the right-hand side of an assignment to a variable of union type is equivalent to storing in a member of the union with the same type union foo u; /* … */ u = (union foo) x ≡ u.i = x u = (union foo) y ≡ u.d = y You can also use the union cast as a function argument: void hack (union foo); /* … */ hack ((union foo) x); Next: Non-Lvalue Arrays May Have Subscripts , Previous: Unnamed Structure and Union Fields , Up: Array, Union, and Struct Extensions [ Contents ][ Index ] | 2026-01-13T09:30:36 |

https://pubs.opengroup.org/onlinepubs/9799919799/functions/read.html | read <<< Previous Home Next >>> The Open Group Base Specifications Issue 8 IEEE Std 1003.1-2024 Copyright © 2001-2024 The IEEE and The Open Group NAME pread, read — read from a file SYNOPSIS #include < unistd.h > ssize_t pread(int fildes , void * buf , size_t nbyte , off_t offset ); ssize_t read(int fildes , void * buf , size_t nbyte ); DESCRIPTION The read () function shall attempt to read nbyte bytes from the file associated with the open file descriptor, fildes , into the buffer pointed to by buf . The behavior of multiple concurrent reads on the same pipe, FIFO, or terminal device is unspecified. Before any action described below is taken, and if nbyte is zero, the read () function may detect and return errors as described below. In the absence of errors, or if error detection is not performed, the read () function shall return zero and have no other results. On files that support seeking (for example, a regular file), the read () shall start at a position in the file given by the file offset associated with fildes . The file offset shall be incremented by the number of bytes actually read. Files that do not support seeking—for example, terminals—always read from the current position. The value of a file offset associated with such a file is undefined. No data transfer shall occur past the current end-of-file. If the starting position is at or after the end-of-file, 0 shall be returned. If the file refers to a device special file, the result of subsequent read () requests is implementation-defined. If the value of nbyte is greater than {SSIZE_MAX}, the result is implementation-defined. When attempting to read from an empty pipe or FIFO: If no process has the pipe open for writing, read () shall return 0 to indicate end-of-file. If some process has the pipe open for writing and O_NONBLOCK is set, read () shall return -1 and set errno to [EAGAIN]. If some process has the pipe open for writing and O_NONBLOCK is clear, read () shall block the calling thread until some data is written or the pipe is closed by all processes that had the pipe open for writing. When attempting to read a file (other than a pipe or FIFO) that supports non-blocking reads and has no data currently available: If O_NONBLOCK is set, read () shall return -1 and set errno to [EAGAIN]. If O_NONBLOCK is clear, read () shall block the calling thread until some data becomes available. The use of the O_NONBLOCK flag has no effect if there is some data available. The read () function reads data previously written to a file. If any portion of a regular file prior to the end-of-file has not been written, read () shall return bytes with value 0. For example, lseek () allows the file offset to be set beyond the end of existing data in the file. If data is later written at this point, subsequent reads in the gap between the previous end of data and the newly written data shall return bytes with value 0 until data is written into the gap. Upon successful completion, where nbyte is greater than 0, read () shall mark for update the last data access timestamp of the file, and shall return the number of bytes read. This number shall never be greater than nbyte . The value returned may be less than nbyte if the number of bytes left in the file is less than nbyte , if the read () request was interrupted by a signal, or if the file is a pipe or FIFO or special file and has fewer than nbyte bytes immediately available for reading. For example, a read () from a file associated with a terminal may return one typed line of data. If a read () is interrupted by a signal before it reads any data, it shall return -1 with errno set to [EINTR]. If a read () is interrupted by a signal after it has successfully read some data, it shall return the number of bytes read. For regular files, no data transfer shall occur past the offset maximum established in the open file description associated with fildes . If fildes refers to a socket, read () shall be equivalent to recv () with no flags set. [ SIO ] If the O_DSYNC and O_RSYNC bits have been set, read I/O operations on the file descriptor shall complete as defined by synchronized I/O data integrity completion. If the O_SYNC and O_RSYNC bits have been set, read I/O operations on the file descriptor shall complete as defined by synchronized I/O file integrity completion. [ SHM ] If fildes refers to a shared memory object, the result of the read () function is unspecified. [ TYM ] If fildes refers to a typed memory object, the result of the read () function is unspecified. The pread () function shall be equivalent to read (), except that it shall read from a given position in the file without changing the file offset. The first three arguments to pread () are the same as read () with the addition of a fourth argument offset for the desired position inside the file. An attempt to perform a pread () on a file that is incapable of seeking shall result in an error. RETURN VALUE Upon successful completion, these functions shall return a non-negative integer indicating the number of bytes actually read. Otherwise, the functions shall return -1 and set errno to indicate the error. ERRORS These functions shall fail if: [EAGAIN] The file is neither a pipe, nor a FIFO, nor a socket, the O_NONBLOCK flag is set for the file descriptor, and the thread would be delayed in the read operation. [EBADF] The fildes argument is not a valid file descriptor open for reading. [EINTR] The read operation was terminated due to the receipt of a signal, and no data was transferred. [EIO] The process is a member of a background process group attempting to read from its controlling terminal, and either the calling thread is blocking SIGTTIN or the process is ignoring SIGTTIN or the process group of the process is orphaned. This error may also be generated for implementation-defined reasons. [EISDIR] [ XSI ] The fildes argument refers to a directory and the implementation does not allow the directory to be read using read () or pread (). The readdir () function should be used instead. [EOVERFLOW] The file is a regular file, nbyte is greater than 0, the starting position is before the end-of-file, and the starting position is greater than or equal to the offset maximum established in the open file description associated with fildes . The pread () function shall fail if: [EINVAL] The file is a regular file or block special file, and the offset argument is negative. The file offset shall remain unchanged. [ESPIPE] The file is incapable of seeking. The read () function shall fail if: [EAGAIN] The file is a pipe or FIFO, the O_NONBLOCK flag is set for the file descriptor, and the thread would be delayed in the read operation. [EAGAIN] or [EWOULDBLOCK] The file is a socket, the O_NONBLOCK flag is set for the file descriptor, and the thread would be delayed in the read operation. [ECONNRESET] A read was attempted on a socket and the connection was forcibly closed by its peer. [ENOTCONN] A read was attempted on a socket that is not connected. [ETIMEDOUT] A read was attempted on a socket and a transmission timeout occurred. These functions may fail if: [EIO] A physical I/O error has occurred. [ENOBUFS] Insufficient resources were available in the system to perform the operation. [ENOMEM] Insufficient memory was available to fulfill the request. [ENXIO] A request was made of a nonexistent device, or the request was outside the capabilities of the device. The following sections are informative. EXAMPLES Reading Data into a Buffer The following example reads data from the file associated with the file descriptor fd into the buffer pointed to by buf . #include <sys/types.h> #include <unistd.h> ... char buf[20]; size_t nbytes; ssize_t bytes_read; int fd; ... nbytes = sizeof(buf); bytes_read = read(fd, buf, nbytes); ... APPLICATION USAGE None. RATIONALE This volume of POSIX.1-2024 does not specify the value of the file offset after an error is returned; there are too many cases. For programming errors, such as [EBADF], the concept is meaningless since no file is involved. For errors that are detected immediately, such as [EAGAIN], clearly the offset should not change. After an interrupt or hardware error, however, an updated value would be very useful and is the behavior of many implementations. Note that a read () of zero bytes does not modify the last data access timestamp. A read () that requests more than zero bytes, but returns zero, is required to modify the last data access timestamp. Implementations are allowed, but not required, to perform error checking for read () requests of zero bytes. Input and Output The use of I/O with large byte counts has always presented problems. Ideas such as lread () and lwrite () (using and returning long s) were considered at one time. The current solution is to use abstract types on the ISO C standard function to read () and write () . The abstract types can be declared so that existing functions work, but can also be declared so that larger types can be represented in future implementations. It is presumed that whatever constraints limit the maximum range of size_t also limit portable I/O requests to the same range. This volume of POSIX.1-2024 also limits the range further by requiring that the byte count be limited so that a signed return value remains meaningful. Since the return type is also a (signed) abstract type, the byte count can be defined by the implementation to be larger than an int can hold. The standard developers considered adding atomicity requirements to a pipe or FIFO, but recognized that due to the nature of pipes and FIFOs there could be no guarantee of atomicity of reads of {PIPE_BUF} or any other size that would be an aid to applications portability. This volume of POSIX.1-2024 requires that no action be taken for read () or write () when nbyte is zero. This is not intended to take precedence over detection of errors (such as invalid buffer pointers or file descriptors). This is consistent with the rest of this volume of POSIX.1-2024, but the phrasing here could be misread to require detection of the zero case before any other errors. A value of zero is to be considered a correct value, for which the semantics are a no-op. I/O is intended to be atomic to ordinary files and pipes and FIFOs. Atomic means that all the bytes from a single operation that started out together end up together, without interleaving from other I/O operations. It is a known attribute of terminals that this is not honored, and terminals are explicitly (and implicitly permanently) excepted, making the behavior unspecified. The behavior for other device types is also left unspecified, but the wording is intended to imply that future standards might choose to specify atomicity (or not). There were recommendations to add format parameters to read () and write () in order to handle networked transfers among heterogeneous file system and base hardware types. Such a facility may be required for support by the OSI presentation of layer services. However, it was determined that this should correspond with similar C-language facilities, and that is beyond the scope of this volume of POSIX.1-2024. The concept was suggested to the developers of the ISO C standard for their consideration as a possible area for future work. In 4.3 BSD, a read () or write () that is interrupted by a signal before transferring any data does not by default return an [EINTR] error, but is restarted. In 4.2 BSD, 4.3 BSD, and the Eighth Edition, there is an additional function, select () , whose purpose is to pause until specified activity (data to read, space to write, and so on) is detected on specified file descriptors. It is common in applications written for those systems for select () to be used before read () in situations (such as keyboard input) where interruption of I/O due to a signal is desired. The issue of which files or file types are interruptible is considered an implementation design issue. This is often affected primarily by hardware and reliability issues. There are no references to actions taken following an "unrecoverable error". It is considered beyond the scope of this volume of POSIX.1-2024 to describe what happens in the case of hardware errors. Earlier versions of this standard allowed two very different behaviors with regard to the handling of interrupts. In order to minimize the resulting confusion, it was decided that POSIX.1-2024 should support only one of these behaviors. Historical practice on AT&T-derived systems was to have read () and write () return -1 and set errno to [EINTR] when interrupted after some, but not all, of the data requested had been transferred. However, the US Department of Commerce FIPS 151-1 and FIPS 151-2 require the historical BSD behavior, in which read () and write () return the number of bytes actually transferred before the interrupt. If -1 is returned when any data is transferred, it is difficult to recover from the error on a seekable device and impossible on a non-seekable device. Most new implementations support this behavior. The behavior required by POSIX.1-2024 is to return the number of bytes transferred. POSIX.1-2024 does not specify when an implementation that buffers read ()s actually moves the data into the user-supplied buffer, so an implementation may choose to do this at the latest possible moment. Therefore, an interrupt arriving earlier may not cause read () to return a partial byte count, but rather to return -1 and set errno to [EINTR]. Consideration was also given to combining the two previous options, and setting errno to [EINTR] while returning a short count. However, not only is there no existing practice that implements this, it is also contradictory to the idea that when errno is set, the function responsible shall return -1. This volume of POSIX.1-2024 intentionally does not specify any pread () errors related to pipes, FIFOs, and sockets other than [ESPIPE]. FUTURE DIRECTIONS None. SEE ALSO fcntl () , lseek () , open () , pipe () , readv () XBD 11. General Terminal Interface , <sys/uio.h> , <unistd.h> CHANGE HISTORY First released in Issue 1. Derived from Issue 1 of the SVID. Issue 5 The DESCRIPTION is updated for alignment with the POSIX Realtime Extension and the POSIX Threads Extension. Large File Summit extensions are added. The pread () function is added. Issue 6 The DESCRIPTION and ERRORS sections are updated so that references to STREAMS are marked as part of the XSI STREAMS Option Group. The following new requirements on POSIX implementations derive from alignment with the Single UNIX Specification: The DESCRIPTION now states that if read () is interrupted by a signal after it has successfully read some data, it returns the number of bytes read. In Issue 3, it was optional whether read () returned the number of bytes read, or whether it returned -1 with errno set to [EINTR]. This is a FIPS requirement. In the DESCRIPTION, text is added to indicate that for regular files, no data transfer occurs past the offset maximum established in the open file description associated with fildes . This change is to support large files. The [EOVERFLOW] mandatory error condition is added. The [ENXIO] optional error condition is added. Text referring to sockets is added to the DESCRIPTION. The following changes were made to align with the IEEE P1003.1a draft standard: The effect of reading zero bytes is clarified. The DESCRIPTION is updated for alignment with IEEE Std 1003.1j-2000 by specifying that read () results are unspecified for typed memory objects. New RATIONALE is added to explain the atomicity requirements for input and output operations. The following error conditions are added for operations on sockets: [EAGAIN], [ECONNRESET], [ENOTCONN], and [ETIMEDOUT]. The [EIO] error is made optional. The following error conditions are added for operations on sockets: [ENOBUFS] and [ENOMEM]. The readv () function is split out into a separate reference page. IEEE Std 1003.1-2001/Cor 2-2004, item XSH/TC2/D6/108 is applied, updating the [EAGAIN] error in the ERRORS section from "the process would be delayed" to "the thread would be delayed". IEEE Std 1003.1-2001/Cor 2-2004, item XSH/TC2/D6/109 is applied, making an editorial correction in the RATIONALE section. Issue 7 The pread () function is moved from the XSI option to the Base. Functionality relating to the XSI STREAMS option is marked obsolescent. Changes are made related to support for finegrained timestamps. POSIX.1-2008, Technical Corrigendum 1, XSH/TC1-2008/0480 [218], XSH/TC1-2008/0481 [79], XSH/TC1-2008/0482 [218], XSH/TC1-2008/0483 [218], XSH/TC1-2008/0484 [218], and XSH/TC1-2008/0485 [218,428] are applied. POSIX.1-2008, Technical Corrigendum 2, XSH/TC2-2008/0302 [710] and XSH/TC2-2008/0303 [676,710] are applied. Issue 8 Austin Group Defect 1330 is applied, removing obsolescent interfaces.

http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/private-content-restricting-access-to-s3.html | Restrict access to an Amazon S3 origin - Amazon CloudFront Restrict access to an Amazon S3 origin - Amazon CloudFront Documentation Amazon CloudFront Developer Guide Create a new origin access control Delete a distribution with an OAC attached to an S3 bucket Migrating from origin access identity (OAI) to origin access control (OAC) Advanced settings for origin access control Use an origin access identity (legacy, not recommended) Restrict access to an Amazon S3 origin CloudFront provides two ways to send authenticated requests to an Amazon S3 origin: origin access control (OAC) and origin access identity (OAI). OAC helps you secure your origins, such as Amazon S3. We recommend that you use OAC instead because it supports the following features: All Amazon S3 buckets in all AWS Regions, including opt-in Regions launched after December 2022 Amazon S3 server-side encryption with AWS KMS (SSE-KMS) Dynamic requests ( PUT and DELETE ) to Amazon S3 OAI doesn't support these features or it requires extra workarounds in those scenarios. If you're already using OAI and want to migrate, see Migrating from origin access identity (OAI) to origin access control (OAC) . Notes When you use CloudFront OAC with Amazon S3 bucket origins, you must set Amazon S3 Object Ownership to Bucket owner enforced , the default for new Amazon S3 buckets. If you require ACLs, use the Bucket owner preferred setting to maintain control over objects uploaded via CloudFront. If your origin is an Amazon S3 bucket configured as a website endpoint , you must set it up with CloudFront as a custom origin. That means you can't use OAC (or OAI). OAC doesn't support origin redirect by using Lambda@Edge. The following topics describe how to use OAC with an Amazon S3 origin. Topics Create a new origin access control Delete a distribution with an OAC attached to an S3 bucket Migrating from origin access identity (OAI) to origin access control (OAC) Advanced settings for origin access control Create a new origin access control Complete the steps described in the following topics to set up a new origin access control in CloudFront. Topics Prerequisites Grant CloudFront permission to access the S3 bucket Create the origin access control Prerequisites Before you create and set up origin access control (OAC), you must have a CloudFront distribution with an Amazon S3 bucket origin. This origin must be a regular S3 bucket, not a bucket configured as a website endpoint . For more information about setting up a CloudFront distribution with an S3 bucket origin, see Get started with a CloudFront standard distribution . Important When you use OAC to secure your Amazon S3 origin, communication between CloudFront and Amazon S3 is always through HTTPS, but only when you choose to always sign requests . You must choose Sign requests (recommended) in the console or specify always in the CloudFront API, AWS CLI, or CloudFormation. If you choose either the Do not sign requests or Do not override authorization header option instead, CloudFront uses the connection protocol that you specified in the following policies: Viewer protocol policy Origin protocol policy (custom origins only) For example, if you choose Do not override authorization header and want to use HTTPS between CloudFront and your Amazon S3 origin, use Redirect HTTP to HTTPS or HTTPS only for the viewer protocol policy . Grant CloudFront permission to access the S3 bucket Before you create an origin access control (OAC) or set it up in a CloudFront distribution, make sure that CloudFront has permission to access the S3 bucket origin. Do this after creating a CloudFront distribution, but before adding the OAC to the S3 origin in the distribution configuration. Use an S3 bucket policy to allow the CloudFront service principal ( cloudfront.amazonaws.com ) to access the bucket. Use a Condition element in the policy to allow CloudFront to access the bucket only when the request is on behalf of the CloudFront distribution that contains the S3 origin. This is the distribution with the S3 origin that you want to add OAC to. For information about adding or modifying a bucket policy, see Adding a bucket policy using the Amazon S3 console in the Amazon S3 User Guide . The following are examples of S3 bucket policies that allow a CloudFront distribution with OAC enabled access to an S3 origin. Example S3 bucket policy that allows read-only access for a CloudFront distribution with OAC enabled JSON { "Version":"2012-10-17", "Statement": [ { "Sid": "AllowCloudFrontServicePrincipalReadOnly", "Effect": "Allow", "Principal": { "Service": "cloudfront.amazonaws.com" }, "Action": "s3:GetObject", "Resource": "arn:aws:s3:::amzn-s3-demo-bucket/*", "Condition": { "StringEquals": { "AWS:SourceArn": "arn:aws:cloudfront::111122223333:distribution/ <CloudFront distribution ID> " } } } ] } Example S3 bucket policy that allows read and write access for a CloudFront distribution with OAC enabled JSON { "Version":"2012-10-17", "Statement": [ { "Sid": "AllowCloudFrontServicePrincipalReadWrite", "Effect": "Allow", "Principal": { "Service": "cloudfront.amazonaws.com" }, "Action": [ "s3:GetObject", "s3:PutObject" ], "Resource": "arn:aws:s3:::amzn-s3-demo-bucket/*", "Condition": { "StringEquals": { "AWS:SourceArn": "arn:aws:cloudfront::111122223333:distribution/ CloudFront-distribution-ID> " } } } ] } SSE-KMS If the objects in the S3 bucket origin are encrypted using server-side encryption with AWS Key Management Service (SSE-KMS) , you must make sure that the CloudFront distribution has permission to use the AWS KMS key. To give the CloudFront distribution permission to use the KMS key, add a statement to the KMS key policy . For information about how to modify a key policy, see Changing a key policy in the AWS Key Management Service Developer Guide . Example KMS key policy statement The following example shows a AWS KMS policy statement that allows the CloudFront distribution with OAC to access a KMS key for SSE-KMS. { "Sid": "AllowCloudFrontServicePrincipalSSE-KMS", "Effect": "Allow", "Principal": { "Service": [ "cloudfront.amazonaws.com" ] }, "Action": [ "kms:Decrypt", "kms:Encrypt", "kms:GenerateDataKey*" ], "Resource": "*", "Condition": { "StringEquals": { "AWS:SourceArn": "arn:aws:cloudfront:: 111122223333 :distribution/ <CloudFront distribution ID> " } } } Create the origin access control To create an origin access control (OAC), you can use the AWS Management Console, CloudFormation, the AWS CLI, or the CloudFront API. Console To create an origin access control Sign in to the AWS Management Console and open the CloudFront console at https://console.aws.amazon.com/cloudfront/v4/home . In the navigation pane, choose Origin access . Choose Create control setting . On the Create control setting form, do the following: In the Details pane, enter a Name and (optionally) a Description for the origin access control. In the Settings pane, we recommend that you leave the default setting ( Sign requests (recommended) ). For more information, see Advanced settings for origin access control . Choose S3 from the Origin type dropdown. Choose Create . After the OAC is created, make note of the Name . You need this in the following procedure. To add an origin access control to an S3 origin in a distribution Open the CloudFront console at https://console.aws.amazon.com/cloudfront/v4/home . Choose a distribution with an S3 origin that you want to add the OAC to, then choose the Origins tab. Select the S3 origin that you want to add the OAC to, then choose Edit . For Origin access , choose Origin access control settings (recommended) . From the Origin access control dropdown menu, choose the OAC that you want to use. Choose Save changes . The distribution starts deploying to all of the CloudFront edge locations. When an edge location receives the new configuration, it signs all requests that it sends to the S3 bucket origin. CloudFormation To create an origin access control (OAC) with CloudFormation, use the AWS::CloudFront::OriginAccessControl resource type. The following example shows the CloudFormation template syntax, in YAML format, for creating an origin access control. Type: AWS::CloudFront::OriginAccessControl Properties: OriginAccessControlConfig: Description: An optional description for the origin access control Name: ExampleOAC OriginAccessControlOriginType: s3 SigningBehavior: always SigningProtocol: sigv4 For more information, see AWS::CloudFront::OriginAccessControl in the AWS CloudFormation User Guide . CLI To create an origin access control with the AWS Command Line Interface (AWS CLI), use the aws cloudfront create-origin-access-control command. You can use an input file to provide the input parameters for the command, rather than specifying each individual parameter as command line input. To create an origin access control (CLI with input file) Use the following command to create a file that's named origin-access-control.yaml . This file contains all of the input parameters for the create-origin-access-control command. aws cloudfront create-origin-access-control --generate-cli-skeleton yaml-input > origin-access-control.yaml Open the origin-access-control.yaml file that you just created. Edit the file to add a name for the OAC, a description (optional), and change the SigningBehavior to always . Then save the file. For information about other OAC settings, see Advanced settings for origin access control . Use the following command to create the origin access control using the input parameters from the origin-access-control.yaml file. aws cloudfront create-origin-access-control --cli-input-yaml file://origin-access-control.yaml Make note of the Id value in the command output. You need it to add the OAC to an S3 bucket origin in a CloudFront distribution. To attach an OAC to an S3 bucket origin in an existing distribution (CLI with input file) Use the following command to save the distribution configuration for the CloudFront distribution that you want to add the OAC to. The distribution must have an S3 bucket origin. aws cloudfront get-distribution-config --id <CloudFront distribution ID> --output yaml > dist-config.yaml Open the file that's named dist-config.yaml that you just created. Edit the file, making the following changes: In the Origins object, add the OAC's ID to the field that's named OriginAccessControlId . Remove the value from the field that's named OriginAccessIdentity , if one exists. Rename the ETag field to IfMatch , but don't change the field's value. Save the file when finished. Use the following command to update the distribution to use the origin access control. aws cloudfront update-distribution --id <CloudFront distribution ID> --cli-input-yaml file://dist-config.yaml The distribution starts deploying to all of the CloudFront edge locations. When an edge location receives the new configuration, it signs all requests that it sends to the S3 bucket origin. API To create an origin access control with the CloudFront API, use CreateOriginAccessControl . For more information about the fields that you specify in this API call, see the API reference documentation for your AWS SDK or other API client. After you create an origin access control you can attach it to an S3 bucket origin in a distribution, using one of the following API calls: To attach it to an existing distribution, use UpdateDistribution . To attach it to a new distribution, use CreateDistribution . For both of these API calls, provide the origin access control ID in the OriginAccessControlId field, inside an origin. For more information about the other fields that you specify in these API calls, see All distribution settings reference and the API reference documentation for your AWS SDK or other API client. Delete a distribution with an OAC attached to an S3 bucket If you need to delete a distribution with an OAC attached to an S3 bucket, you should delete the distribution before you delete the S3 bucket origin. Alternatively, include the Region in the origin domain name. If this isn't possible, you can remove the OAC from the distribution by switching to public before deletion. For more information, see Delete a distribution . Migrating from origin access identity (OAI) to origin access control (OAC) To migrate from a legacy origin access identity (OAI) to an origin access control (OAC), first update the S3 bucket origin to allow both the OAI and the distribution with OAC enabled to access the bucket's content. This makes sure that CloudFront never loses access to the bucket during the transition. To allow both OAI and the distribution with OAC enabled to access an S3 bucket, update the bucket policy to include two statements, one for each kind of principal. The following example S3 bucket policy allows both an OAI and a distribution with OAC enabled to access an S3 origin. Example S3 bucket policy that allows read-only access for an OAI and a CloudFront distribution with OAC enabled JSON { "Version":"2012-10-17", "Statement": [ { "Sid": "AllowCloudFrontServicePrincipalReadOnly", "Effect": "Allow", "Principal": { "Service": "cloudfront.amazonaws.com" }, "Action": "s3:GetObject", "Resource": "arn:aws:s3::: <S3 bucket name> /*", "Condition": { "StringEquals": { "AWS:SourceArn": "arn:aws:cloudfront:: 111122223333 :distribution/ <CloudFront distribution ID> " } } }, { "Sid": "AllowLegacyOAIReadOnly", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity <origin access identity ID> " }, "Action": "s3:GetObject", "Resource": "arn:aws:s3::: <S3 bucket name> /*" } ] } After you update the S3 origin's bucket policy to allow access to both OAI and OAC, you can update the distribution configuration to use OAC instead of OAI. For more information, see Create a new origin access control . After the distribution is fully deployed, you can remove the statement in the bucket policy that allows access to the OAI. For more information, see Grant CloudFront permission to access the S3 bucket . Advanced settings for origin access control The CloudFront origin access control feature includes advanced settings that are intended only for specific use cases. Use the recommended settings unless you have a specific need for the advanced settings. Origin access control contains a setting named Signing behavior (in the console), or SigningBehavior (in the API, CLI, and CloudFormation). This setting provides the following options: Always sign origin requests (recommended setting) We recommend using this setting, named Sign requests (recommended) in the console, or always in the API, CLI, and CloudFormation. With this setting, CloudFront always signs all requests that it sends to the S3 bucket origin. Never sign origin requests This setting is named Do not sign requests in the console, or never in the API, CLI, and CloudFormation. Use this setting to turn off origin access control for all origins in all distributions that use this origin access control. This can save time and effort compared to removing an origin access control from all origins and distributions that use it, one by one. With this setting, CloudFront does not sign any requests that it sends to the S3 bucket origin. Warning To use this setting, the S3 bucket origin must be publicly accessible. If you use this setting with an S3 bucket origin that's not publicly accessible, CloudFront cannot access the origin. The S3 bucket origin returns errors to CloudFront and CloudFront passes those errors on to viewers. Don't override the viewer (client) Authorization header This setting is named Do not override authorization header in the console, or no-override in the API, CLI, and CloudFormation. Use this setting when you want CloudFront to sign origin requests only when the corresponding viewer request does not include an Authorization header. With this setting, CloudFront passes on the Authorization header from the viewer request when one is present, but signs the origin request (adding its own Authorization header) when the viewer request doesn't include an Authorization header. Warning To pass along the Authorization header from the viewer request, you must add the Authorization header to a cache policy for all cache behaviors that use S3 bucket origins associated with this origin access control. Use an origin access identity (legacy, not recommended) CloudFront origin access identity (OAI) provides similar functionality as origin access control (OAC), but it doesn't work for all scenarios. Specifically, OAI doesn't support: Amazon S3 buckets in all AWS Regions, including opt-in Regions Amazon S3 server-side encryption with AWS KMS (SSE-KMS) Dynamic requests ( PUT , POST , or DELETE ) to Amazon S3 New AWS Regions launched after January 2023 Tip We recommend that you use OAC instead. To set up OAC, see Create a new origin access control . For information about how to migrate from OAI to OAC, see Migrating from origin access identity (OAI) to origin access control (OAC) . When you create an OAI or add one to a distribution with the CloudFront console, you can automatically update the Amazon S3 bucket policy to give the OAI permission to access your bucket. Alternatively, you can choose to manually create or update the bucket policy. Whichever method you use, you should still review the permissions to make sure that: Your CloudFront OAI can access files in the bucket on behalf of viewers who are requesting them through CloudFront. Viewers can't use Amazon S3 URLs to access your files outside of CloudFront. Important If you configure CloudFront to accept and forward all of the HTTP methods that CloudFront supports, make sure you give your CloudFront OAI the desired permissions. For example, if you configure CloudFront to accept and forward requests that use the DELETE method, configure your bucket policy to handle DELETE requests appropriately so viewers can delete only files that you want them to. Use Amazon S3 bucket policies You can give a CloudFront OAI access to files in an Amazon S3 bucket by creating or updating the bucket policy in the following ways: Using the Amazon S3 bucket's Permissions tab in the Amazon S3 console . Using PutBucketPolicy in the Amazon S3 API. Using the CloudFront console . When you add an OAI to your origin settings in the CloudFront console, you can choose Yes, update the bucket policy to tell CloudFront to update the bucket policy on your behalf. If you update the bucket policy manually, make sure that you: Specify the correct OAI as the Principal in the policy. Give the OAI the permissions it needs to access objects on behalf of viewers. For more information, see the following sections. Specify an OAI as the Principal in a bucket policy To specify an OAI as the Principal in an Amazon S3 bucket policy, use the OAI's Amazon Resource Name (ARN), which includes the OAI's ID. For example: "Principal": { "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity <origin access identity ID> " } Find the OAI ID in the CloudFront console under Security , Origin access , Identities (legacy) . Alternatively, use ListCloudFrontOriginAccessIdentities in the CloudFront API. Give permissions to an OAI To give the OAI the permissions to access objects in your Amazon S3 bucket, use actions in the policy that relate to specific Amazon S3 API operations. For example, the s3:GetObject action allows the OAI to read objects in the bucket. For more information, see the examples in the following section, or see Amazon S3 actions in the Amazon Simple Storage Service User Guide . Amazon S3 bucket policy examples The following examples show Amazon S3 bucket policies that allow CloudFront OAI to access an S3 bucket. Find the OAI ID in the CloudFront console under Security , Origin access , Identities (legacy) . Alternatively, use ListCloudFrontOriginAccessIdentities in the CloudFront API. Example Amazon S3 bucket policy that gives the OAI read access The following example allows the OAI to read objects in the specified bucket ( s3:GetObject ). JSON { "Version":"2012-10-17", "Id": "PolicyForCloudFrontPrivateContent", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity <origin access identity ID> " }, "Action": "s3:GetObject", "Resource": "arn:aws:s3::: <S3 bucket name> /*" } ] } Example Amazon S3 bucket policy that gives the OAI read and write access The following example allows the OAI to read and write objects in the specified bucket ( s3:GetObject and s3:PutObject ). This allows viewers to upload files to your Amazon S3 bucket through CloudFront. JSON { "Version":"2012-10-17", "Id": "PolicyForCloudFrontPrivateContent", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity <origin access identity ID> " }, "Action": [ "s3:GetObject", "s3:PutObject" ], "Resource": "arn:aws:s3::: <S3 bucket name> /*" } ] } Use Amazon S3 object ACLs (not recommended) Important We recommend using Amazon S3 bucket policies to give an OAI access to an S3 bucket. You can use access control lists (ACLs) as described in this section, but we don't recommend it. Amazon S3 recommends setting S3 Object Ownership to bucket owner enforced , which means that ACLs are disabled for the bucket and the objects in it. When you apply this setting for Object Ownership, you must use bucket policies to give access to the OAI (see the previous section). This following section is only for legacy use cases that require ACLs. You can give a CloudFront OAI access to files in an Amazon S3 bucket by creating or updating the file's ACL in the following ways: Using the Amazon S3 object's Permissions tab in the Amazon S3 console . Using PutObjectAcl in the Amazon S3 API. When you grant access to an OAI using an ACL, you must specify the OAI using its Amazon S3 canonical user ID. In the CloudFront console, you can find this ID under Security , Origin access , Identities (legacy) . If you're using the CloudFront API, use the value of the S3CanonicalUserId element that was returned when you created the OAI, or call ListCloudFrontOriginAccessIdentities in the CloudFront API. Newer Amazon S3 Regions require that you use Signature Version 4 for authenticated requests. (For the signature versions supported in each Amazon S3 Region, see Amazon Simple Storage Service endpoints and quotas in the AWS General Reference .) If you're using an origin access identity and if your bucket is in one of the Regions that requires Signature Version 4, note the following: DELETE , GET , HEAD , OPTIONS , and PATCH requests are supported without qualifications. POST requests are not supported. Javascript is disabled or is unavailable in your browser. To use the Amazon Web Services Documentation, Javascript must be enabled.

http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/lambda-event-structure.html#lambda-event-structure-response-origin | Lambda@Edge event structure - Amazon CloudFront Lambda@Edge event structure - Amazon CloudFront Documentation Amazon CloudFront Developer Guide Dynamic origin selection Request events Response events Lambda@Edge event structure The following topics describe the request and response event objects that CloudFront passes to a Lambda@Edge function when it's triggered. Topics Dynamic origin selection Request events Response events Dynamic origin selection You can use the path pattern in a cache behavior to route requests to an origin based on the path and name of the requested object, such as images/*.jpg . Using Lambda@Edge, you can also route requests to an origin based on other characteristics, such as the values in request headers. There are a number of ways that this dynamic origin selection can be useful. For example, you can distribute requests across origins in different geographic areas to help with global load balancing. Or you can selectively route requests to different origins that each serve a particular function: bot handling, SEO optimization, authentication, and so on. For code examples that demonstrate how to use this feature, see Content-based dynamic origin selection - examples . In the CloudFront origin request event, the origin object in the event structure contains information about the origin that the request would be routed to, based on the path pattern. You can update the values in the origin object to route a request to a different origin. When you update the origin object, you don't need to define the origin in the distribution. You can also replace an Amazon S3 origin object with a custom origin object, and vice versa. You can only specify a single origin per request, though; either a custom origin or an Amazon S3 origin, but not both. Request events The following topics show the structure of the object that CloudFront passes to a Lambda function for viewer and origin request events . These examples show a GET request with no body. Following the examples is a list of all the possible fields in viewer and origin request events. Topics Example viewer request Example origin request Request event fields Example viewer request The following example shows a viewer request event object. { "Records": [ { "cf": { "config": { "distributionDomainName": "d111111abcdef8.cloudfront.net", "distributionId": "EDFDVBD6EXAMPLE", "eventType": "viewer-request", "requestId": "4TyzHTaYWb1GX1qTfsHhEqV6HUDd_BzoBZnwfnvQc_1oF26ClkoUSEQ==" }, "request": { "clientIp": "203.0.113.178", "headers": { "host": [ { "key": "Host", "value": "d111111abcdef8.cloudfront.net" } ], "user-agent": [ { "key": "User-Agent", "value": "curl/7.66.0" } ], "accept": [ { "key": "accept", "value": "*/*" } ] }, "method": "GET", "querystring": "", "uri": "/" } } } ] } Example origin request The following example shows an origin request event object. { "Records": [ { "cf": { "config": { "distributionDomainName": "d111111abcdef8.cloudfront.net", "distributionId": "EDFDVBD6EXAMPLE", "eventType": "origin-request", "requestId": "4TyzHTaYWb1GX1qTfsHhEqV6HUDd_BzoBZnwfnvQc_1oF26ClkoUSEQ==" }, "request": { "clientIp": "203.0.113.178", "headers": { "x-forwarded-for": [ { "key": "X-Forwarded-For", "value": "203.0.113.178" } ], "user-agent": [ { "key": "User-Agent", "value": "Amazon CloudFront" } ], "via": [ { "key": "Via", "value": "2.0 2afae0d44e2540f472c0635ab62c232b.cloudfront.net (CloudFront)" } ], "host": [ { "key": "Host", "value": "example.org" } ], "cache-control": [ { "key": "Cache-Control", "value": "no-cache" } ] }, "method": "GET", "origin": { "custom": { "customHeaders": { }, "domainName": "example.org", "keepaliveTimeout": 5, "path": "", "port": 443, "protocol": "https", "readTimeout": 30, "responseCompletionTimeout": 30, "sslProtocols": [ "TLSv1", "TLSv1.1", "TLSv1.2" ] } }, "querystring": "", "uri": "/" } } } ] } Request event fields Request event object data is contained in two subobjects: config ( Records.cf.config ) and request ( Records.cf.request ). The following lists describe each subobject's fields. Fields in the config object The following list describes the fields in the config object ( Records.cf.config ). distributionDomainName (read-only) The domain name of the distribution that's associated with the request. distributionID (read-only) The ID of the distribution that's associated with the request. eventType (read-only) The type of trigger that's associated with the request: viewer-request or origin-request . requestId (read-only) An encrypted string that uniquely identifies a viewer-to-CloudFront request. The requestId value also appears in CloudFront access logs as x-edge-request-id . For more information, see Access logs (standard logs) and Log file fields . Fields in the request object The following list describes the fields in the request object ( Records.cf.request ). clientIp (read-only) The IP address of the viewer that made the request. If the viewer used an HTTP proxy or a load balancer to send the request, the value is the IP address of the proxy or load balancer. headers (read/write) The headers in the request. Note the following: The keys in the headers object are lowercase versions of standard HTTP header names. Using lowercase keys gives you case-insensitive access to the header values. Each header object (for example, headers["accept"] or headers["host"] ) is an array of key–value pairs. For a given header, the array contains one key–value pair for each value in the request. key contains the case-sensitive name of the header as it appeared in the HTTP request; for example, Host , User-Agent , X-Forwarded-For , Cookie , and so on. value contains the header value as it appeared in the HTTP request. When your Lambda function adds or modifies request headers and you don't include the header key field, Lambda@Edge automatically inserts a header key using the header name that you provide. Regardless of how you've formatted the header name, the header key that's inserted automatically is formatted with initial capitalization for each part, separated by hyphens (-). For example, you can add a header like the following, without a header key : "user-agent": [ { "value": "ExampleCustomUserAgent/1.X.0" } ] In this example, Lambda@Edge automatically inserts "key": "User-Agent" . For information about restrictions on header usage, see Restrictions on edge functions . method (read-only) The HTTP method of the request. querystring (read/write) The query string, if any, in the request. If the request doesn't include a query string, the event object still includes querystring with an empty value. For more information about query strings, see Cache content based on query string parameters . uri (read/write) The relative path of the requested object. If your Lambda function modifies the uri value, note the following: The new uri value must begin with a forward slash (/). When a function changes the uri value, that changes the object that the viewer is requesting. When a function changes the uri value, that doesn't change the cache behavior for the request or the origin that the request is sent to. body (read/write) The body of the HTTP request. The body structure can contain the following fields: inputTruncated (read-only) A Boolean flag that indicates whether the body was truncated by Lambda@Edge. For more information, see Restrictions on the request body with the include body option . action (read/write) The action that you intend to take with the body. The options for action are the following: read-only: This is the default. When returning the response from the Lambda function, if action is read-only, Lambda@Edge ignores any changes to encoding or data . replace: Specify this when you want to replace the body sent to the origin. encoding (read/write) The encoding for the body. When Lambda@Edge exposes the body to the Lambda function, it first converts the body to base64-encoding. If you choose replace for the action to replace the body, you can opt to use base64 (the default) or text encoding. If you specify encoding as base64 but the body is not valid base64, CloudFront returns an error. data (read/write) The request body content. origin (read/write) (origin events only) The origin to send the request to. The origin structure must contain exactly one origin , which can be a custom origin or an Amazon S3 origin. Depending on your origin type that you specify (custom or Amazon S3 origins), you must specify the following fields in your request: customHeaders (read/write) (custom and Amazon S3 origins) (Optional) You can include custom headers with the request by specifying a header name and value pair for each custom header. You can't add headers that are disallowed, and a header with the same name can't be present in Records.cf.request.headers . The notes about request headers also apply to custom headers. For more information, see Custom headers that CloudFront can’t add to origin requests and Restrictions on edge functions . domainName (read/write) (custom and Amazon S3 origins) The domain name of the origin. The domain name can't be empty. For custom origins – Specify a DNS domain name, such as www.example.com . The domain name can't include a colon (:), and can't be an IP address. The domain name can be up to 253 characters. For Amazon S3 origins – Specify the DNS domain name of the Amazon S3 bucket, such as amzn-s3-demo-bucket.s3.eu-west-1.amazonaws.com . The name can be up to 128 characters, and must be all lowercase. path (read/write) (custom and Amazon S3 origins) The directory path at the origin where the request should locate content. The path should start with a forward slash (/) but shouldn't end with one (for example, it shouldn't end with example-path/ ). For custom origins only, the path should be URL encoded and have a maximum length of 255 characters. keepaliveTimeout (read/write) (custom origins only) How long, in seconds, that CloudFront should try to maintain the connection to the origin after receiving the last packet of the response. The value must be a number from 1–120, inclusive. port (read/write) (custom origins only) The port that CloudFront should connect to at your custom origin. The port must be 80, 443, or a number in the range of 1024–65535, inclusive. protocol (read/write) (custom origins only) The connection protocol that CloudFront should use when connecting to your origin. The value can be http or https . readTimeout (read/write) (custom and Amazon S3 origins) How long, in seconds, CloudFront should wait for a response after sending a request to your origin. This also specifies how long CloudFront should wait after receiving a packet of a response before receiving the next packet. The value must be a number from 1–120, inclusive. If you need a higher quota, see Response timeout per origin . responseCompletionTimeout (read/write) (custom and Amazon S3 origins) The time (in seconds) that a request from CloudFront to the origin can stay open and wait for a response. If the complete response isn't received from the origin by this time, CloudFront ends the connection. The value for responseCompletionTimeout must be equal to or greater than the value for the readTimeout . If you set this value to 0, it removes any previous value you set and returns to the default. You can also accomplish this by deleting the responseCompletionTimeout field from the event request. sslProtocols (read/write) (custom origins only) The minimum SSL/TLS protocol that CloudFront can use when establishing an HTTPS connection with your origin. Values can be any of the following: TLSv1.2 , TLSv1.1 , TLSv1 , or SSLv3 . authMethod (read/write) (Amazon S3 origins only) If you're using an origin access identity (OAI) , set this field to origin-access-identity . If you aren't using an OAI, set it to none . If you set authMethod to origin-access-identity , there are several requirements: You must specify the region (see the following field). You must use the same OAI when you change the request from one Amazon S3 origin to another. You can't use an OAI when you change the request from a custom origin to an Amazon S3 origin. Note This field does not support origin access control (OAC) . region (read/write) (Amazon S3 origins only) The AWS Region of your Amazon S3 bucket. This is required only when you set authMethod to origin-access-identity . Response events The following topics show the structure of the object that CloudFront passes to a Lambda function for viewer and origin response events . Following the examples is a list of all the possible fields in viewer and origin response events. Topics Example origin response Example viewer response Response event fields Example origin response The following example shows an origin response event object. { "Records": [ { "cf": { "config": { "distributionDomainName": "d111111abcdef8.cloudfront.net", "distributionId": "EDFDVBD6EXAMPLE", "eventType": "origin-response", "requestId": "4TyzHTaYWb1GX1qTfsHhEqV6HUDd_BzoBZnwfnvQc_1oF26ClkoUSEQ==" }, "request": { "clientIp": "203.0.113.178", "headers": { "x-forwarded-for": [ { "key": "X-Forwarded-For", "value": "203.0.113.178" } ], "user-agent": [ { "key": "User-Agent", "value": "Amazon CloudFront" } ], "via": [ { "key": "Via", "value": "2.0 8f22423015641505b8c857a37450d6c0.cloudfront.net (CloudFront)" } ], "host": [ { "key": "Host", "value": "example.org" } ], "cache-control": [ { "key": "Cache-Control", "value": "no-cache" } ] }, "method": "GET", "origin": { "custom": { "customHeaders": { }, "domainName": "example.org", "keepaliveTimeout": 5, "path": "", "port": 443, "protocol": "https", "readTimeout": 30, "responseCompletionTimeout": 30, "sslProtocols": [ "TLSv1", "TLSv1.1", "TLSv1.2" ] } }, "querystring": "", "uri": "/" }, "response": { "headers": { "access-control-allow-credentials": [ { "key": "Access-Control-Allow-Credentials", "value": "true" } ], "access-control-allow-origin": [ { "key": "Access-Control-Allow-Origin", "value": "*" } ], "date": [ { "key": "Date", "value": "Mon, 13 Jan 2020 20:12:38 GMT" } ], "referrer-policy": [ { "key": "Referrer-Policy", "value": "no-referrer-when-downgrade" } ], "server": [ { "key": "Server", "value": "ExampleCustomOriginServer" } ], "x-content-type-options": [ { "key": "X-Content-Type-Options", "value": "nosniff" } ], "x-frame-options": [ { "key": "X-Frame-Options", "value": "DENY" } ], "x-xss-protection": [ { "key": "X-XSS-Protection", "value": "1; mode=block" } ], "content-type": [ { "key": "Content-Type", "value": "text/html; charset=utf-8" } ], "content-length": [ { "key": "Content-Length", "value": "9593" } ] }, "status": "200", "statusDescription": "OK" } } } ] } Example viewer response The following example shows a viewer response event object. { "Records": [ { "cf": { "config": { "distributionDomainName": "d111111abcdef8.cloudfront.net", "distributionId": "EDFDVBD6EXAMPLE", "eventType": "viewer-response", "requestId": "4TyzHTaYWb1GX1qTfsHhEqV6HUDd_BzoBZnwfnvQc_1oF26ClkoUSEQ==" }, "request": { "clientIp": "203.0.113.178", "headers": { "host": [ { "key": "Host", "value": "d111111abcdef8.cloudfront.net" } ], "user-agent": [ { "key": "User-Agent", "value": "curl/7.66.0" } ], "accept": [ { "key": "accept", "value": "*/*" } ] }, "method": "GET", "querystring": "", "uri": "/" }, "response": { "headers": { "access-control-allow-credentials": [ { "key": "Access-Control-Allow-Credentials", "value": "true" } ], "access-control-allow-origin": [ { "key": "Access-Control-Allow-Origin", "value": "*" } ], "date": [ { "key": "Date", "value": "Mon, 13 Jan 2020 20:14:56 GMT" } ], "referrer-policy": [ { "key": "Referrer-Policy", "value": "no-referrer-when-downgrade" } ], "server": [ { "key": "Server", "value": "ExampleCustomOriginServer" } ], "x-content-type-options": [ { "key": "X-Content-Type-Options", "value": "nosniff" } ], "x-frame-options": [ { "key": "X-Frame-Options", "value": "DENY" } ], "x-xss-protection": [ { "key": "X-XSS-Protection", "value": "1; mode=block" } ], "age": [ { "key": "Age", "value": "2402" } ], "content-type": [ { "key": "Content-Type", "value": "text/html; charset=utf-8" } ], "content-length": [ { "key": "Content-Length", "value": "9593" } ] }, "status": "200", "statusDescription": "OK" } } } ] } Response event fields Response event object data is contained in three subobjects: config ( Records.cf.config ), request ( Records.cf.request ), and response ( Records.cf.response ).
