34,785,653 | PyODBC : can't open the driver even if it exists | <p>I'm new to the linux world and I want to query a Microsoft SQL Server from Python. I used it on Windows and it was perfectly fine but in Linux it's quite painful.</p>
<p>After some hours, I finally succeed to install the Microsoft ODBC driver on Linux Mint with unixODBC.</p>
<p>Then, I set up an anaconda with python 3 environment. </p>
<p>I then do this :</p>
<pre><code>import pyodbc as odbc
sql_PIM = odbc.connect("Driver={ODBC Driver 13 for SQL Server};Server=XXX;Database=YYY;Trusted_Connection=Yes")
</code></pre>
<p>It returns :</p>
<pre><code>('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/opt/microsoft/msodbcsql/lib64/libmsodbcsql-13.0.so.0.0' : file not found (0) (SQLDriverConnect)")
</code></pre>
<p>The thing I do not undertsand is that PyODBC seems to read the right filepath from odbcinst.ini and still does not work.</p>
<p>I went to "/opt/microsoft/msodbcsql/lib64/libmsodbcsql-13.0.so.0.0" and the file actually exists !</p>
<p>So why does it tell me that it does not exist ?
Here are some possible clues :</p>
<ul>
<li>I'm on a virtual environment</li>
<li>I need to have "read" rights because it's a root filepath</li>
</ul>
<p>I do not know how to solve either of these problems.</p>

34,790,455 | PHP WITH MS SQL SERVER DOWNLOADING AND CONNECTING | I have a project written in php.Also,another application is written in C(sharp) with Ms Sql as the database engine. I want to fetch some data from the Ms Sql database and use it in php. I have tried many solution provided on stackover and other site, but none seems to work.Below are what I have done, maybe there is a place where i am missing something:
1. I Downloaded drivers(Ms Drivers for php) and loads it into the C:\wamp\bin\php\php5.5.12\ext directories.files are
php_pdo_sqlsrv_55_nts.dll
php_pdo_sqlsrv_55_ts.dll
php_sqlsrv_55_nts.dll
php_sqlsrv_55_ts.dll
2. Modify the php.ini by including the following in the extension area:
extension=php_pdo_sqlsrv_55_nts.dll
extension=php_pdo_sqlsrv_55_ts.dll
extension=php_sqlsrv_55_nts.dll
extension=php_sqlsrv_55_ts.dll
Infact, one of the site says I should rename by removing the "_55_xx", so that it looks like php_sqlsrv.dll.yet it is still not working.
3. Restart the Apache server and discovered that the included files not activated or seen when you click on the wamp monitor,navigate to the php and view the extension directory.
I have search and search,seems to be given up, but thought it better to communicate with others who can be of assistance. I currently use wamp and php version is php5.5.12. Please, I need a solution on how to get working drivers to connect my php with Ms Sql server and get data from the server seamlessly.

34,792,795 | C# - What does passing by ref do? | I know what passing by ref is and what it means but what exactly does it do with the objects passed by ref?
Does it guarantee the objects to stay at their current position in memory while the reference is being used?
Does the behavior change between local objects and global objects?
I'm mostly interested with what happens in memory.
**A bit of background information:**
I have written a simple test program that stores the memory address of objects passed by ref and noticed how C# likes to move objects around in memory. But what I think is odd was that the objects being used were locals of a function. This automatically makes me think that the object's reference can't move in memory because it is on the stack. But clearly I'm missing something. What kind of memory was I receiving when using the ref? | <c#> | 2016-01-14 15:05:03 | LQ_EDIT |

<p>The disassembly of this particular function continues on, but one thing I noticed is the relatively large number of <code>call</code> instructions like this one:</p>
<pre><code>20: e8 00 00 00 00 callq 25 <bar<foo, 0u>::get(bool)+0x25>
</code></pre>
<p>These instructions, always with the opcode <code>e8 00 00 00 00</code>, occur frequently throughout the generated code, and from what I can tell, are nothing more than no-ops; they all seem to just fall through to the next instruction. This begs the question, then, is there a good reason why all these instructions are generated? </p>
<p>I'm concerned about the instruction cache footprint of the generated code, so wasting 5 bytes many times throughout a function seems counterproductive. It seems a bit heavyweight for a <code>nop</code>, unless the compiler is trying to preserve some kind of memory alignment or something. I wouldn't be surprised if this were the case.</p>
<p>I compiled my code using g++ 4.8.5 using <code>-O3 -fomit-frame-pointer</code>. For what it's worth, I saw similar code generation using clang 3.7.</p>

34,795,577 | What logic determines the insert order of Entity Framework 6 | <p>So, I have a DBContext, and I am doing the following operations:</p>
<pre><code>dbContext.SomeTables1.Add(object1)
dbContext.SomeTables2.AddRange(objectArray2)
dbContext.SomeTables3.AddRange(objectArray3)
dbContext.SaveChanges();
</code></pre>
<p>The EF doesn't insert the db records in this order, it inserts them in a random order. To insert them in the same order, I have to do a <code>dbContext.SaveChanges()</code> after each addition. This is not an efficient solution and in my case, it is taking 10 seconds to do all my inserts, while the random order with one save takes around 3 seconds.</p>
<p>N.B. I need the right order to solve a deadlock issue.</p>
<p>My questions are:</p>
<blockquote>
<ul>
<li>Is this issue resolved in EF7?</li>
<li>I can profile EF and determine the random order, however, is there a guarantee that it will be consistently with the same random order or
does it change between requests? (I can adopt my other code if the
answer to this question is positive).</li>
<li>Is there a better way of maintaining the order than <code>dbContext.SaveChanges()</code> on every addition?</li>

34,811,540 | How to build a Fluent Nested Guard API | <p>I am building a simple Guard API to protect against illegal parameters being passed to functions and so on.</p>
<p>I have the following code:</p>
<pre><code>public static class Guard
{
public static GuardArgument<T> Ensure<T>(T value, string argumentName)
{
return new GuardArgument<T>(value, argumentName);
}
}
public class GuardArgument<T>
{
public GuardArgument(T value, string argumentName)
{
Value = value;
Name = Name;
}
public T Value { get; private set; }
public string Name { get; private set; }
}
// Example extension for validity checks
public static GuardArgument<T> IsNotNull<T>(this GuardArgument<T> guardArgument, string errorMessage)
{
if (guardArgument.Value == null)
{
throw new ArgumentNullException(guardArgument.Name, errorMessage);
}
return guardArgument;
}
</code></pre>
<p>At the moment the code can be used in a similar way to (note this is just a dumb example):</p>
<pre><code>void DummyMethod(int? someObject) {
Guard.Ensure(someObject, "someObject")
.IsNotNull()
.IsGreaterThan(0)
.IsLessThan(10);
}
</code></pre>
<p>This all works fine. What I want to be able to do now is extend the API to include child properties in the checks in the following way:</p>
<pre><code>Guard.Ensure(someObject, "someObject")
.IsNotNull()
.Property(
(x => x.ChildProp1, "childProp1")
.IsNotNull()
.IsGreaterThan(10)
)
.Property(
(x => x.ChildProp2, "childProp2")
.IsNotNull()
.IsLessThan(10)
);
</code></pre>
<p>Obviously the new <code>.Property</code> method needs to return the parent <code>GuardArgument</code> in order to chain. Furthermore the child property needs to be able to use the existing check methods (<code>IsNotNull()</code> etc) to avoid code duplication.</p>
<p>I cannot work out how to construct the lambda/Property function parameters or where the <code>.Property</code> method should be located - i.e. should it be a property on the <code>GuardArgument</code> or somewhere else, or even if there is a better structure to the API.</p>

<p>You'll notice the scrolling is smooth when you comment out the call to <code>fillLabels</code>. </p>
<p>If you try to reproduce the same layout without <code>UIStackViews</code> and include the call <code>fillLabels</code>, you'll notice the scrolling is smooth too.</p>
<p>This suggests <code>UIStackView</code> suffers performance bottlenecks if it has recalculate its layout. </p>

34,813,412 | How to detect if building with address sanitizer when building with gcc 4.8? | <p>I'm working on a program written in C that I occasionally build with address sanitizer, basically to catch bugs. The program prints a banner in the logs when it starts up with info such as: who built it, the branch it was built on, compiler etc. I was thinking it would be nice to also spell out if the binary was built using address sanitizer. I know there's __has_feature(address_sanitizer), but that only works for clang. I tried the following simple program: </p>
<pre><code>#include <stdio.h>
int main()
{
#if defined(__has_feature)
# if __has_feature(address_sanitizer)
printf ("We has ASAN!\n");
# else

# endif
#else
printf ("We got nothing!\n");
#endif
return 0;

34,816,577 | When can I use a SFSafariViewController, WKWebView, or UIWebView with universal links? | <p>In the <a href="https://developer.apple.com/library/ios/documentation/General/Conceptual/AppSearch/UniversalLinks.html#//apple_ref/doc/uid/TP40016308-CH12-SW1" rel="noreferrer">Universal Links</a> section of the <a href="https://developer.apple.com/library/ios/documentation/General/Conceptual/AppSearch/index.html" rel="noreferrer">iOS App Search Programming Guide</a>, Apple says:</p>
<blockquote>
<p>If you instantiate a SFSafariViewController, WKWebView, or UIWebView
object to handle a universal link, iOS opens your website in Safari
instead of opening your app. However, if the user taps a universal
link from within an embedded SFSafariViewController, WKWebView, or
UIWebView object, iOS opens your app.</p>
</blockquote>
<p>What does "handle a universal link" mean? Can I not ever open the given URL with an <code>SFSafariViewController</code>, <code>WKWebView</code>, or <code>UIWebView</code>? Does it only apply during <code>-[UIApplicationDelegate application:continueUserActivity:restorationHandler:]</code>, or is there a timeout in place? Does this mean we can't ever open the URL in a <code>SFSafariViewController</code>, <code>WKWebView</code>, or <code>UIWebView</code>?</p>

34,816,578 | How to detect API modifications when mocking e2e tests? | <p>I'd like to setup a solid e2e testing foundation on our team's project but I can't find a simple solution to that question :</p>
<p><strong>When you are mocking all of your calls, what is the best way to detect if the actual model of the objects returned by your server has been modified ?</strong></p>
<p>Your tests would still pass because they're testing an outdated version of the model but the app is potentially broken.</p>
<p>For example, if a mock assumes that <code>/api/users/1</code> returns <code>null</code> if the user doesn't exist, when it actually returns an empty object, then although the tests may pass, the behaviour being tested relies on incorrect assumptions and may therefore fail in unexpected ways.</p>
<p>Or maybe the backend is somehow providing static json files with the latest up-to-date model and the frontend relies on this ?</p>
<p>This of course supposes that the people working on the backend and the people working on the frontend are separate teams.</p>
<p>I am using Angular 1.x and Protractor here but this doesn't really depend on the technology.</p>

34,817,380 | How do we set constant variables while building R packages? | <p>We are building a package in R for our service (a robo-advisor here in Brazil) and we send requests all the time to our external API inside our functions. </p>
<p>As it is the first time we build a package we have some questions. :(</p>
<p>When we will use our package to run some scripts we will need some information as <code>api_path, login, password</code>.</p>
<p>How do we place this information inside our package? </p>
<p>Here is a real example:</p>
<pre><code>get_asset_daily <- function(asset_id) {
api_path <- "https://api.verios.com.br"
url <- paste0(api_path, "/assets/", asset_id, "/dailies?asc=d")
data <- fromJSON(url)
data
}
</code></pre>
<p>Sometimes we use a <code>staging</code> version of the API and we have to constantly switch paths. How we should call it inside our function? </p>
<p>Should we set a global environment variable, a package environment variable, just define <code>api_path</code> in our scripts or a package config file?</p>
<p>How do we do that? </p>

34,818,533 | How to compare two Streams in Java 8 | <p>What would be a good way to compare two <code>Stream</code> instances in Java 8 and find out whether they have the same elements, specifically for purposes of unit testing?</p>
<p>What I've got now is:</p>
<pre><code>@Test
void testSomething() {
Stream<Integer> expected;
Stream<Integer> thingUnderTest;
// (...)
Assert.assertArrayEquals(expected.toArray(), thingUnderTest.toArray());
}
</code></pre>
<p>or alternatively:</p>
<pre><code>Assert.assertEquals(
expected.collect(Collectors.toList()),
thingUnderTest.collect(Collectors.toList()));
</code></pre>
<p>But that means I'm constructing two collections and discarding them. It's not a performance issue, given the size of my test streams, but I'm wondering whether there's a canonical way to compare two streams.</p>

34,820,755 | Gitlab docker executor - cache image after before_script | <p>In <code>gitlab-ci</code> there's an option in the <a href="http://doc.gitlab.com/ce/ci/yaml/README.html" rel="noreferrer"><code>.gitlab-ci.yml</code></a> file to execute commands before any of the actual script runs, called <code>before_script</code>. <code>.gitlab-ci.yml</code> examples illustrate installing ancillary programs here. However, what I've noticed is that these changes are not cached in Docker when using a docker executor. I had naively assumed that after running these commands, docker would cache the image, so for the next run or test, docker would just load the cached image produced after <code>before_script</code>. This would drastically speed up builds.</p>
<p>As an example, my <code>.gitlab-ci.yml</code> looks a little like:</p>
<pre><code>image: ubuntu
before_script:
- apt-get update -qq && apt-get install -yqq make ...
build:
script:
- cd project && make
</code></pre>
<p>A possible solution is to go to the runner machine and create a docker image that can build my software without any other installation and then reference it in the <code>image</code> section of the yaml file. The downside of this is that whenever I want to add a dependency, I need to log in to the runner machine and update the image before builds will succeed. It would be much nicer if I just had to add the dependency to to the end of <code>apt-get install</code> and have docker / gitlab-ci handle the appropriate caching.</p>
<p>There is also a <code>cache</code> command in <code>.gitlab-ci.yml</code>, which I tried setting to <code>untracked: true</code>, which I thought would cache everything that wasn't a byproduct of my project, but it didn't seem to have any effect.</p>
<p>Is there any way to get the behavior I desire?</p>

34,820,817 | ESLint's "no-undef" rule is calling my use of Underscore an undefined variable | <p>I am using Grunt as my Build Tool and ESLint as my linting tool for an app I am working on. I am also using the Underscore Node package, and have made use of it in my app. Unfortunately, when I run ESLint on my code, it thinks that _ is an undefined variable in the following line:</p>
<p><code>return _.pluck(objects, nameColumn);</code></p>
<p>This is the error it is giving me:</p>
<p><code>78:21 error "_" is not defined no-undef</code></p>
<p>I would prefer not to disable the no-undef rule for ESLint, and I have tried installing the Underscore plugin, but I am still receiving this error. If anyone else has any ideas for what to try with this, I would be very appreciative!</p>
<p>If there is any further information I can give that would help anyone with helping me get this figured out, just let me know!</p>

34,820,975 | Git clone: Redirect stderr to stdout but keep errors being written to stderr | <p><code>git clone</code> writes its output to <code>stderr</code> as documented <a href="https://www.kernel.org/pub/software/scm/git/docs/git-clone.html">here</a>. I can redirect this with the following command:</p>
<pre><code>git clone https://myrepo c:\repo 2>&1

<p>But this will redirect all output, including errors, from <code>stderr</code>to <code>stdout</code>. Is there a way to redirect progress messages to <code>stdout</code> but have error messages still written to <code>stderr</code>. </p>
