You can use packagemaker. It makes myapp.pkg file that when double-clicked installa an app in Applications location.

I had developed an app in python on mac osx for opening different file types on double-clicking any file. Then I converted into app by using py2app. py2app creates a myapp.app within dist folder. I moved myapp.app from dist folder to Applications location. Now, I am able to open any file through myapp just by double-clicking on it. Now, I want to make it work in such a way that, I don't need to drag and drop myapp to Applications location,it should automatically install on system.

py2app has a "--dist-dir" option for selecting the output directory (default is "diet"). That said, I have never tested using that option for installation in a directory containing other programs and don't know if "python setup.py py2app --dist-dir=/Applications" is save to use. The alternative is to use a script that copies the application to /Applications (a simple python script, a shell script, or even a distutils command in your setup.py file that invokes py2app and then copies the resulting application to the right location).

What is the difference between using HttpUwsgiModule for NGINX and using NGINX as a reverseproxy to uWSGI?

Simply put, when you use HttpUwsgiModule NGINX speaks the uwsgi protocol and it can leave out useless informations of the http protocol leading to less overhead and thus better performance.

I need to run a python code that takes several hours and my computer disconnects from the ssh after a certain amount of inactive time. I have tried python test.py > output.txt & but my output file is empty. However, the python code "test" is still running after I log off and log back in to the ssh. I also tried python -u test.py > output.txt & which does write to the output.txt but it does not continue after the ssh connection is lost. I am very new to Linux so I do not know very many commands. I need the simplest/easiest to understand method. Thanks!

No, %%script magic are autogenerated and don't do any magic inter-process data communication. (which is not the case for %%R but which is a separate magic in its own class with extra care from R peoples) But writing your own magic that does it is not too hard to do.

performance for xarg vs. python multiprocessing+subprocess

19,580,680

python,unix,multiprocessing,xargs

The xargs program will collect multiple arguments from standard input, and glue them together to make one long command line. If there are many many many arguments, too long for one command line, then it will build and execute multiple command lines, as many as needed. This means less overhead for starting up processes and shutting them down. How much good this will do for you depends on how long your processes run. If you are starting up some sort of CPU-intensive program that will run for half an hour, the startup time for the process will be inconsequential. If you are starting up a program that runs quickly, but you are only running a small number of instances, again the savings will be inconsequential. However, if your program is truly trivial and requires minimal runtime, maybe you will notice a difference. From your problem description, it appears to be a good candidate for this. 10K things with relatively short processing for each. xargs might speed things up for you. However, in my experience, doing any nontrivial work in shell scripts brings the pain. If you have any directory names or file names that can have a space in them, the slightest mistake in quoting your variables makes your script crash, so you need to obsessively test your script to make sure it will work for all possible inputs. For this reason, I do my nontrivial system scripts in Python. Therefore, if you already have your program working in Python, IMHO you would be crazy to try to rewrite it as a shell script. Now, you can still use xargs if you want. Just use subprocess to run xargs and pass all the arguments via standard input. This gains all of the benefit and none of the pain. You can use Python to stick a NUL byte chr(0) at the end of each argument, and then use xargs --null, and it will be robust with filenames that have spaces in them. Alternatively you could use ' '.join() to build your own very long command lines, but I don't see any reason to do that when you can just run xargs as described above.

I have a question on the performance scalability with xargs. Currently I have a batch processing program written in python with multiprocessing and subprocess. Each process spawns an independent subprocess.popen() to execute an external command. Recently I realized that the whole process can be redone with xargs. However, I wonder whether it is a good idea to use xargs to process 10k+ files since I have never done something this scale with only commandline tools before. Given my test with small data sets, it is actually not a bad idea if all I am doing is batch running a bunch of commands, since it avoids many cycles of overhead imposed by python's modules, but I would like to learn more from anyone who may have more experience with xargs and python. More specifically, is there any buffer limit that I need to configure for xargs to consume a large number of inputs? Thanks.

The df command displays the amount of disk space occupied by mounted or unmounted file systems, the amount of used and available space, and how much of the file system's total capacity has been used. Linux has df command in the following location /bin whereas in Solaris in the following location /usr/gnu/bin... If suppose /usr/bin is set in the PATH, then programmatically, i need to ensure that one of required df (as mentioned above) is invoked instead of the user defined df. One solution to this problem is using uname to get the OS and set the df accordingly... Is there any other better way to do this where i am not dependent on the OS.

Are the target systems somehow under your control, and does this involve a limited set of servers? If so, how about adding a soft link in both the Solaris and Linux servers, in the same location and with the same name? Something like: Solaris: ln -s /usr/gnu/bin/df /usr/bin/my_df Linux: ln -s /bin/df /usr/bin/my_df Then let your script use /usr/bin/my_df for every box. Not fancy and rather simple approach... but maybe it would work for you? Just my 2c.

This was originally a comment, but it seems to be what OP wants, so I'm reposting it as an answer I would use ctrl+z to suspend your live, running process. This will leave you with a PID, which you can later resume with a call to fg: fg <job-number>. This shouldn't have any implications with changed network settings (like IP, etc), at least as far as python is concerned. I can't speak to whether the API will freak out, though

I run python scripts on my macbook air that process data from external API's and often take several hours or occasionally even days. However, sometimes I need to suspend my laptop in the middle of running a script so I can go to work or go home or similar. How can I simply pause/resume these scripts in the middle of their for loops? Is there something very simple that I can add at the script level that just listens for a particular key stroke to stop/start? Or something I can do at the *nix process management level? I'm well aware of Pickle but I'd rather not deal with the hassle of serializing/unserializing my data--since all I'm doing is hibernating the mac, I'm hoping if the script gets paused and then I hibernate, that OS X will handle saving the RAM to disk and then restoring back to RAM when I reopen the computer. At that point, I can hit a simple keystroke to continue the python script. Since I'm switching between different wifi networks, not sure if the different IPs will cause problems when my script tries to access the internet to reach the 3rd party APIs.

This goes out to anyone who is well versed in the Eclipse IDE and or PyDev perspective plug-in who is willing to offer some technical support. I am trying to write a python module that must take in arguments from the command prompt with sys.argv function calls. Rather than printing out the correct output when I enter E:\ ... \src>program.py arg1 arg2, all that happens is a new command line (E:\ ... \src>) is output and the Eclipse IDE window flashes orange without any code in my python module actually being executed. Also, if I close the Eclipse IDE and try to run program.py, it will just open Eclipse again and open my program in a new tab. I'm confused as to why it is not working now when just last week it was working perfectly while testing another program that took in arguments from the command prompt by sys.argv function calls. My question for everyone is whether or not you are aware of any settings that may have been altered by updates, etc. that could cause this problem; or has anybody out there ever run into this problem and figured out how to resolve it? I have already checked my PATH variable, so that is not the problem :-(. Any help you can provide would be greatly appreciated ... thank you.

Yes, you can use Python to do what you want. Google designs their services (such as GAE and endpoints) to be language agnostic, e.g. using JSON to serialize objects. There are a few advantages to using Java on both, such as being able to share code between client and service projects, but Google does not promote such dependencies at all - you will have no problem using Python instead.

Am I confused as to what is possible between an Android Client and Google App Engine? I would like to be able to create a Python API that would handle requests between GAE services such as Datastore, and an Android Client. I have found some examples that detail how to make a call from within an Android Client, but it doesn't seem to outline whether or not you can pass data to any specific API language. The question I have is whether or not it is possible to use a Python API deployed on GAE and making calls through Google End Points, or would I have to use Java Servlets to handle requests?

But when I checked python version from my application (Django using with FastCGI) I still see that it is using 2.5. In ps output I see python processes running for this account and apache processes runing with hosting-specific account. How can I switch this particular account to 2.7 without changing system-wide version? Thanks!

Handling of arbitrary options using Tornado options, i.e. like **kwargs

python,python-2.7,tornado,keyword-argument

The tornado.options philosophy is that any module may define options, not just the main entry point. So if you might need a bluetooth mac address, you'd define that option in the module that interacts with bluetooth. (and if you might need more than one you can set multiple=True). The only tricky part is that you must import all modules that define options before calling parse_command_line. Truly arbitrary options are not supported by tornado.options. It's also possible to use argparse or another command-line library instead of tornado.options.parse_command_line - the rest of tornado doesn't care whether you're using tornado.options or not.

I'm using Tornado options to define command-line arguments. However, I would like to be able to throw arbitrary configuration options, not defined in code, to my program. These will differ, depending on what the program is supposed to do. For instance, connect to a bluetooth device using a MAC address or connect to a serial device using a TTY. If I define a set of "mandatory" options in code and then add an additional when calling the program, I get an exception thrown by parse_command_line(). It would be very handy to get e.g. a dictionary with the remaining (undefined) options. That is, much in the same way as **kwargs works in functions. Can this be done? (A work-around is to define a string option named e.g. configuration and throw everything in there, possibly encoded in some clever way. As the program is being called by another program I can e.g. base64-encode a serialized dict.) Update: I've noticed that if you add command-line args without leading dashes, Tornado will ignore them and return a list with remaining (undefined) options.

If you want to execute some third party native code which you know is not stable and may crash with a segvault then it is better to execute it as a subprocess - you will be able to safely handle the possible crashes from your Python process. Also, if you want to call several times some code which is known to leak memory, leave open files or other resources, from a long running Python process, then again it may be wise to run it as a subprocess. In this case the leaking memory or other resources will be reclaimed by the operating system for you each time the subprocess exits, and not accumulate.

Ubuntu - PySide module not found for python2 but works fine for python3

python,ubuntu,python-2.7,python-3.x,pyside

You have two independent Python 2.7 installations, one in /usr and one in /usr/local. (And that's on top of the Python 3.x installation you also have.) This is bound to cause confusion, especially for novices. And it has caused exactly the kind of consuion it was bound to cause. You've installed PySide into the /usr installation, so it ended up in /usr/lib/python2.7/dist-packages. If you run /usr/bin/python, that import PySide will probably work fine. (If not, see below.) But the default thing called python and python2.7 on your PATH is the /usr/local installation, hence which python says /usr/local/bin/python, so it can't see PySide at all. So you need to get it installed for the other Python as well. Unless you know that you need a second Python 2.7 in /usr/local for some reason, the simplest thing to do would be to scrap it. Don't uninstall it and reinstall it; just uninstall it. You've already got a Python 2.7 in /usr, and you don't need two of them. If you really need to get PySide working with the second 2.7… Since you still haven't explained how you've been installing PySide despite being asked repeatedly, I can't tell you exactly how to do that. But generally, the key is to make sure to use explicit paths for all Python programs (python itself, python-config, pip, easy_install, etc.) that you have to run. For example, if the docs or blog or voices in your head tell you to run easy_install at some step, run /usr/local/bin/easy_install instead. If there is no such program, then you need to install that. The fact that you already have /usr/bin/easy_install doesn't help—in fact, it hurts. If you can get rid of the second Python, but that doesn't fix PySide yet, uninstall, rebuild, and reinstall PySide. Or, even simpler… PySide has pre-made, working binary Ubuntu packages for all of the major Python versions that have Ubuntu packages. Just install it that way.

I had PyQt4 running fine with python2 on Ubuntu 12.04. I then installed python-PySide. But the installation test would give me a module not found error. Then I installed python3-PySide and it works fine. So obviously something to do with my environment paths, but I'm not sure what I need to do. I'm guessing PySide is automatically checking if python3 exists and if it does then it'll use it regardless. I need PySide to work with python2.7 because of Qt4.8 compatibility issues. Any suggestions? some info about my system: which python /usr/bin/local/python which python3 /usr/bin/python3 EDIT: More details about installation test. After installation, I bring up the python console and try import PySide, as follows: python import PySide ImportError: No module name PySide But it works fine for python3: python3 import PySide PySide.version '1.1.2'

Writing the data out to a text file in python and then loading that text file in php is definitely the easiest way. If you're willing to modify the php script, you could make it read the data from stdin, and set up a pipe between the two processes, but this going to be a little trickier.

You don't have to run the webbrowser as root but your django app (the webserver). Of course running a web application as root is an incredibly bad idea (even on a pi), so you might want to use a separate worker process (e.g. using celery) that runs as root and accesses the GPIOs.

You do not need to use S3, you would likely want to use EBS for storing the code if you need it to be preserved between instance launches. When you launch an instance you have the option to add an ebs storage volume to the drive. That drive will automatically be mounted to the instance and you can access it just like you would on any physical machine. ssh your code up to the amazon machine and fire away.

I have never used amazon web services so I apologize for the naive question. I am looking to run my code on a cluster as the quad-core architecture on my local machine doesn't seem to be doing the job. The documentation seems overwhelming and I don't even know which AWS services are going to be used for running my script on EC2. Would I have to use their storage facility (S3) because I guess if I have to run my script, I'm going to have to store it on the cloud in a place where the cluster instance has access to the files or do I upload my files somewhere else while working with EC2? If this is true is it possible for me to upload my entire directory which has all the contents of the files required by my application onto s3. Any guidance would be much appreciated. So I guess my question is do I have to use S3 to store my code in a place accessible by the cluster? If so is there an easy way to do it? Meaning I have only seen examples of creating buckets wherein one file can be transferred per bucket. Can you transfer an entire folder into a bucket? If we don't require to use S3 then which other service should I use to give the cluster access to my scripts to be executed? Thanks in advance!

How can I automate google docs with Google App Engine?

There is currently no API to create google docs directly except for: 1) make a google apps script service, which does have access to the docs api. 2) create a ".doc" then upload and convert to gdoc. 1 is best but a gas service has some limitations like quotas. If you are only creating dozens/hundreds per day you will be ok with quotas. Ive done it this way for something similar as your case.

Listmates: I am designing a google app engine (python) app to automate law office documents. I plan on using GAE, google docs, and google drive to create and store the finished documents. My plan is to have case information (client name, case number, etc.) entered and retrieved using GAE web forms and the google datastore. Then I will allow the user to create a motion or other document by inserting the form data into template. The completed document can be further customized by the user, email, printed, and/or stored in a google drive folder. I found information on how to create a web page that can be printed. However, I am looking for information for how to create an actual google doc and insert the form data into that document or template. Can someone point me to a GAE tutorial of any type that steps me through how to do this?

I have an existing app that uses the deprecated Python 2.5 and the deprecated master/slave datastore. According to the docs, I must migrate the datastore to HRD before I can upgrade to Python 2.7. Before I can migrate my M/S datastore to HRD, I need to do some work on the app and test it using the dev server. However, I upgraded to the most recent version of the SDK (1.8.6), and it does not support Python 2.5. Somebody else encountered this problem and learned that the latest SDK that supports Python 2.5 by default is Python SDK 1.7.5. From where can that be downloaded? Or, is there a way I can make the SDK 1.8.6 work with Python 2.5?

Dave W. Smith gave me the answer but I didn't know how to implement it until I made a discovery that maybe most people already know, But in case it might be helpful to somebody, I will tell it here: I do all my GAE/Python/Flex development work in Eclispe, except that I used the launcher for local testing and deploying. (I am command-line adverse.) I discovered that using the PyDev Eclipse plugin it is easy to set up a "run configuration" (under the PyDev "Run" menu) whereby you can set up command line parameters, etc. and run any python program from within Eclipse. I now use that facility for running dev_appserver.py (and when needed for my Python 2.5 app, old_app_devserver.py). I no longer have a need to use the launcher. I also set up a PyDev run configuation to deploy my app and performing various appcfg.py functions (vacuum indexes, etc.).

Since the supplied information is insufficient, the answer is the same. This is about user authentication. I don't know how you open the app but, your app tries to open a file or a process which is could not be opened by your user. If you open your app with root privileges there won't be any problem.

Multiprocessing on Ubuntu vs OSX and SSD vs HDD

python,multithreading,macos,ubuntu

On hardware level only one operation on a device can be done at once. If the drive is busy, the requested operation is being queued. There are few different queues where it may be waiting and they vary in different operation systems, hardware or even drivers. There are different queue management methods as well most popular on software side is fifo (first in, first out), but on drive side it probably is NCQ (special queue managment that selects closest data to be written/read first) All of those queues have limited size. If hardware level queues are full (for example disk cache have been filled), the system halts all operations of applications requesting disk access. So if your application is doing some disk operations it may simply be waiting for a disk drive. As SSD technology makes whole processing much quicker, an access latency is about 10-20 times faster than in HDD, it is highly probable that your application doesn't use 100% of CPU because of HDD.

Can a HDD vs SSD setup account for lower processor utilization when there are many read and write operations? So I've written a program that spawns multiple processes. On OSX it runs great and utilizes 100% of the cpu. Overloading it with hundreds of threads works out fine. On Ubuntu, it freezes when pushing a large number of threads. When I limit the number of total threads the the max for the processors, the Ubuntu machine doesn't utilize all the computing power--only about 50%. My threads do run at nearly 100% for the first minute or so, then suddently it becomes random with a wave like utilization graph which doesn't always begin at the same time. Specs: OSX, SSD, Intel i7 4 cores x 2 threads each = 8 threads Ubuntu, HDD, 3930K Intel i7 6 cores x 2 threads each = 12 threads

Using the GAE remote_api to Create Local Scripts

Why is including the paths that onerous ? Normally the remote_api shell is used interactively but it is a good tool that you can use as the basis of acheiving what your want. The simplest way will be to copy and modify the remote_api shell so that rather than presenting an interactive shell you get it to run a named script. That way it will deal with all the path setup. In the past I have integrated the remote_api inside a zope server, so that plone could publish stuff to appengine. All sort of things are possible with remote_api, however you need to deal with imports like anything else in python, except that appengine libraries are not installed in site-packages.

I'm trying to do some local processing of data entries from the GAE datastore and I am trying to do this by using the remote_api. I just want to write some quick processing scripts that pull some data, but I am getting import errors saying that Python cannot import from google. Am I supposed to run the script from within the development environment somehow. Or perhaps I need to include all of the google stuff in my Python path? That seems excessive though.

It seems that it's libssl.1.0.0.dylib that is missing. Mavericks comme with libssl 0.9.8. You need to install libssl via homebrew. If loaderpath points to /usr/lib/, you also need to symlink libssl from /usr/local/Cell/openssl/lib/ into /usr/lib.

Shared object location under OS X is sometimes tricky. When you directly call dlopen() you have the freedom of specifying an absolute path to the library, which works fine. However, if you load a library which in turn needs to load another (as appears to be your situation), you've lost control of specifying where the library lives with its direct path. There are environment variables that you could set before running your main program that tell the dynamic loader where to search for things. In general these are a bad idea (but you can read about them via the man dyld command on an OS X system). When an OS X dynamic library is created, it's given an install name; this name is embedded within the binary and can be viewed with the otool command. otool -L mach-o_binary will list the dynamic library references for the mach-o binary you provide the file name to; this can be a primary executable or a dylib, for example. When a dynamic library is statically linked into another executable (either a primary executable or another dylib), the expected location of where that dylib being linked will be found is based on the location written into it (either at the time it was built, or changes that have been applied afterwards). In your case, it seems that phys_services.so was statically linked against libphys-services.dylib. So to start, run otool -L phys_services.so to find the exact expectation of where the dylib will be. The install_name_tool command can be used to change the expected location of a library. It can be run against the dylib before it gets statically linked against (in which case you have nothing left to do), or it can be run against the executable that loads it in order to rewrite those expectations. The command pattern for this is install_name_tool -change <old_path> <new_path> So for example, if otool -L phys_services.so shows you /usr/lib/libphys-services.dylib and you want to move the expectation as you posed in your question, you would do that with install_name_tool -change /usr/lib/libphys-services.dylib @rpath/lib/libphys-services.dylib phys_services.so. The dyld man page (man dyld) will tell you how @rpath is used, as well as other macros @loader_path and @executable_path.

Closing the loop: bdist in the path is a sign that the package was installed with setup.py install and is running from the standard Python system path, not from wherever you have it checked out. Easy fix is to setup.py install it again. Harder fix is to uninstall it and fiddle with Apache's working directory, but that's not quite my area. :)

I'm guessing the problem is that I'm not modifying the correct file or I need to compile the script some how but I'm just not able to find out where/how to do this. I have tried restarting apache but with no luck. Any help or guidance as to where I should be looking or if I need to run some sort of command to re-compile to browser.py file would be appreciated.

If you are working with Spyder, use CTRL+. and you will restart the kernel, also you will stop the program.

Windows solution: Control + C. Macbook solution: Control (^) + C. Another way is to open a terminal, type top, write down the PID of the process that you would like to kill and then type on the terminal: kill -9 <pid>

Ctrl+Z should do it, if you're caught in the python shell. Keep in mind that instances of the script could continue running in background, so under linux you have to kill the corresponding process.

You can also do it if you use the exit() function in your code. More ideally, you can do sys.exit(). sys.exit() which might terminate Python even if you are running things in parallel through the multiprocessing package. Note: In order to use the sys.exit(), you must import it: import sys

If your program is running at an interactive console, pressing CTRL + C will raise a KeyboardInterrupt exception on the main thread. If your Python program doesn't catch it, the KeyboardInterrupt will cause Python to exit. However, an except KeyboardInterrupt: block, or something like a bare except:, will prevent this mechanism from actually stopping the script from running. Sometimes if KeyboardInterrupt is not working you can send a SIGBREAK signal instead; on Windows, CTRL + Pause/Break may be handled by the interpreter without generating a catchable KeyboardInterrupt exception. However, these mechanisms mainly only work if the Python interpreter is running and responding to operating system events. If the Python interpreter is not responding for some reason, the most effective way is to terminate the entire operating system process that is running the interpreter. The mechanism for this varies by operating system. In a Unix-style shell environment, you can press CTRL + Z to suspend whatever process is currently controlling the console. Once you get the shell prompt back, you can use jobs to list suspended jobs, and you can kill the first suspended job with kill %1. (If you want to start it running again, you can continue the job in the foreground by using fg %1; read your shell's manual on job control for more information.) Alternatively, in a Unix or Unix-like environment, you can find the Python process's PID (process identifier) and kill it by PID. Use something like ps aux | grep python to find which Python processes are running, and then use kill <pid> to send a SIGTERM signal. The kill command on Unix sends SIGTERM by default, and a Python program can install a signal handler for SIGTERM using the signal module. In theory, any signal handler for SIGTERM should shut down the process gracefully. But sometimes if the process is stuck (for example, blocked in an uninterruptable IO sleep state), a SIGTERM signal has no effect because the process can't even wake up to handle it. To forcibly kill a process that isn't responding to signals, you need to send the SIGKILL signal, sometimes referred to as kill -9 because 9 is the numeric value of the SIGKILL constant. From the command line, you can use kill -KILL <pid> (or kill -9 <pid> for short) to send a SIGKILL and stop the process running immediately. On Windows, you don't have the Unix system of process signals, but you can forcibly terminate a running process by using the TerminateProcess function. Interactively, the easiest way to do this is to open Task Manager, find the python.exe process that corresponds to your program, and click the "End Process" button. You can also use the taskkill command for similar purposes.

Working on windows platform, I have a python application which once invoked, remembers its state and resumes in case of system crash or reboot. The application actually runs some other executables or in technological terms is of type framework. The typical scenario where the executable need to run with admin mode passes for first time but fails after resuming from crash or reboot. What I believe is I need to invoke the resumed application with admin mode. In what way this could be achieved, Thanks in advance!

I'm building a backup program which involves detecting when media available for backup is inserted. I've looked into detecting the insertion of backup media, and I'm going to use the file system watch service inotify on the /media/username directory. The problem is that I've looked into this directory and there are folders that don't represent any currently available medium. How can I detect the list of currently available mediums (USBs, HDDs) and watch for any future ones? More technically, what are the characteristics of an actively available USB/HDD folder in the /media/username directory?

I'm prototyping a Python/Redis based API and am serving JSON using Bottle but unfortunately out of the box Bottle performs badly under load and under high concurrency. Some initial testing on real traffic results in the python script crashing without terminating, which means the API is unresponsive and not restarting*. What is currently the best solution to scale a Python/Redis API in terms of performance as well as documentation. I find the bottle+greenlet solution poorly documented and not easy to implement for a Python beginner like me. I heard tornado is good but that its integration with Redis is slower than Bottle's. *Seems that when bottle is unable to send the body of the HTTP request to the client, the server will bug out with "[Errno 32] Broken pipe" errors, which seems like a bad reason for a server to stop working

I have a need to execute PERL scripts through a Django web interface. The user will select the parameters of the script and execute it. I am wondering if it is possible to use Celery/RabbitMQ to execute these script as Celery tasks? If so, would I need to modify the PERL script? Would I have to write RabbitMQ code into the PERL scripts? Or would I just execute the Celery task and wait for the script to finish processing? I would like to have the script update the Django user/celery.

Assumptions: You mention python(w).exe and cmd, so you're most likely on windows. You probably selected "use python 2.n" somewhere in your IDE (whichever one you may use). That works fine as long as you ONLY execute your scripts from there. From any arbitrary other place on your system, windows (or any other OS) makes use of environment variables PATH, in this case. (right-click My Computer > advanced > environment variables or something). It probably contains the path to python27.exe C:/Python27, change that to C:/Python25. If multiple directories are used, first order takes precedence. pythonw.exe is a custom executable related to early pywin32 development by Mark Hammond I believe, and yes it should supress the console window during startup.

But, it seems that cmd does not follow this change. How could I fix this? b) what is the difference between running a script using python.exe vs. pythonw.exe? I read somewhere that upon using pythonw.exe, I will not see the cmd window that pops out and disappears. But for my case, this is not true and I actually see the cmd window. Also, if I use python.exe I get an error from running my script but not when I use pythonw.exe.

delphi code compiled to obj files to be used in python

c++,python,c,delphi,.obj

Delphi generated .obj files cannot be consumed by Python because Python doesn't consume .obj files. You'd need to compile them to a library at the very least. At which point, emitting .obj files is pointless – you may as well just output a full module. I conclude that you'll need to compile your Delphi code to a library (DLL) or a COM object. To support multiple platforms, you'll need to compile separately for each platform. Which means that you'll only be able to support platforms on which Delphi compilers exist. FreePascal has wider platform support and may be a better choice. Obviously COM would restrict you to Windows. So the other option is a library. This can be consumed using ctypes or by making your module a Python extension module.

This isn't the nicest solution in the world, but it works with Debian/Ubuntu's overly draconian policies (which don't even make sense; if I can install a binary, why not a pyo?). Hopefully this helps someone out.

When we run the python programs: 1_python source code compile with Cpython to the bytecode (bytecode is the binary file with .pyc format which seralize with marshal and it is set of stack structures that solve with pvm) 2_then the pvm (python virtual machine/python interpreter) is stackbase machine (the machine which solve task with stack data structure) which loop inside bytecode line by line and execute it. What executes the bytecode? The bytecode tells the Python interpreter which C code to execute.

I am trying to understand how Python works (because I use it all the time!). To my understanding, when you run something like python script.py, the script is converted to bytecode and then the interpreter/VM/CPython–really just a C Program–reads in the python bytecode and executes the program accordingly. How is this bytecode read in? Is it similar to how a text file is read in C? I am unsure how the Python code is converted to machine code. Is it the case that the Python interpreter (the python command in the CLI) is really just a precompiled C program that is already converted to machine code and then the python bytecode files are just put through that program? In other words, is my Python program never actually converted into machine code? Is the python interpreter already in machine code, so my script never has to be?

So, I have looked around stack overflow + other sites, but havent been able to solve this problem: hence posting this question! I have recently started learning django... and am now trying to run it on ec2. I have an ec2 instance of this format: ec2-xx-xxx-xx-xxx.us-west-2.compute.amazonaws.com on which I have a django app running. I changed the security group of this instance to allow http port 80 connections. I did try to run it the django app the following ways: python manage.py runserver 0.0.0.0:8000 and python manage.py runserver ec2-xx-xxx-xx-xxx.us-west-2.compute.amazonaws.com:8000 and that doesnt seem to be helping either! To make sure that there is nothing faulty from django's side, I opened another terminal window and ssh'ed into the instance and did a curl GET request to localhost:8000/admin which went through successfully. Where am I going wrong? Will appreciate any help!

To answer your question: No, there aren't any big reasons to not go with Jenkins for deployment. Pros: You already know Jenkins (and you probably know some of the quirks) You don't need to introduce yet another technology You said that you want to write scripts called by Jenkins, so you can switch easily to a different system later. Cons: there might be better tools out there for deployment Does not tie the best with Change Control tools. Additional Considerations: Do not use the same server for prod deployment and continuous build/integration. These are two different tasks performed by two different roles. Therefore two different permission schemes might be employed. Use permissions wisely. I use two different permissions for my deploy and CI servers. We have 3 Jenkins servers right now. CI and deploy to uncontrolled environments (Developers can play with these environments) Deploy to controlled environments. (QA environemnts and upwards) Deploy to prod (yes, that's the only purpose in live of this server.) with the most restrictive permission scheme. sandbox, actually there is this forth server for Jenkins admins to play with. Store your deployable artifacts outside of Jenkins (and you do if I read your question correctly). So depending on your existing infrastructure and procedure you decide for the tooling. Jenkins won't log you in as long as you keep as much of the logic as possible in scripts that are only executed by Jenkins.

We want to use continuous deployment. We have: all sources (python) in a local RhodeCode (git) server. Jenkins for automated testing SSH connections to the production systems (linux). a tool which can update servers in one command. Now something like this should be implemented: run tests with Jenkins if there is a failure. Stop, mail developers If all tests are OK: deploy We are long enough in the business to write some scripts to do this. My questions: How to you update the version numbers? You could increment them, you could use a timestamp ... Since we already use Jenkins, I think we do it in a script called by Jenkins. Any reason to do it with a different (better) tool? My fear: Jenkins becomes a central server for things which are not related to testing (deploy). I think other tools like SaltStack or Ansible should be used for this. Up to now we use Fabric (simple layer above ssh). Maybe we should switch to a central management system before starting with continuous deployment.

How do I make a standalone application out of a Docker container?

In order to use a Docker container, you will always need the basics - Docker installed on a Linux OS (that supports LXC and any other required filesystem type). In a production environment, you'd be running a recent, native install of Linux, and the initial install of Docker would be easy, and a one-time event (in a cloud environment, you'd probably not upgrade a working machine, but instead spin up a new one, with the latest pre-tested Docker version, and the equally upgraded & tested new containers). On a MacOS, or Windows development machine, you need a virtual machine to host the Linux OS. There's no way around that.

The simple answer is: you can't. The long answer is: Docker is not intended to be used to make cross platform standalone applications (but JAVA is, for example). Docker instead focuses on having a light weight container that acts like a virtual machine but basically isn't. It's just a box inside a linux(!) system that behaves like a virtual machine to install services into that can be separated clearly from each other that way. A proper use case example for docker would be to install a web application with a specific version of say apache and php in it to have a definitive environment guaranteed.

A Linux VM is a dependency if you are on Windows or Mac. Vagrant is not though. It is mentioned only because it's probably the easiest way to get a VM up and running.

I am trying to install mesos on CentOs. I downloaded it and run ./configure command. But couldn't be completed due to installed version of python as mesos requires development version 2.6. I tried to upgrade python but it upgrades to 2.4 only. Then I manually download python 2.6 and install, which is located under /usr/local/bin/ and the old one is located under /usr/bin. When I run the python command in terminal it displays python 2.6, but again when I configure mesos it again gives same error. configure: error: in `/root/mesos-0.14.1': configure: error: Could not link test program to Python. Maybe the main Python library has been installed in some non-standard library path. If so, pass it to configure, via the LDFLAGS environment variable. Example: ./configure LDFLAGS="-L/usr/non-standard-path/python/lib" ============================================================================ ERROR! You probably have to install the development version of the Python package for your distribution. The exact name of this package varies among them. ============================================================================ I then create symbolic link of /usr/local/bin/python to /usr/bin/python but now 'yum' command doesn't work also configuring mesos again gives same error. I also tried ./configure LDFLAGS="-L/usr/local/lib/python/lib" .What should I do to install mesos cluster in Cent Os ? What is the solution ?

Git: Master-thesis subprojects as submodules or stand-alone repositories

I recommend a single master repository for this problem. You mentioned that the output files of certain programs are used as input to the others. These programs may not have run-time dependencies on each other, but they do have dependencies. It sounds like they will not work without each other being present to create the data. Especially if file location (e.g. relative path) is important, then a single repository will help you keep them better organized.

I just started using git to get my the code I write for my Master-thesis more organized. I have divided the tasks into 4 sub-folders, each one containing data and programs that work with that data. The 4 sub-projects do not necessarily need to be connected, none off the programs contained use functions from the other sub-projects. However the output-files produced by the programs in a certain sub-folder are used by programs of another sub-folder. In addition some programs are written in Bash and some in Python. I use git in combination with bitbucket. I am really new to the whole concept, so I wonder if I should create one "Master-thesis" repository or rather one repository for each of the (until now) 4 sub-projects. Thank you for your help!

Well, as devnull says, answers would be highly opinion based, but given that I disagree that that's a bad thing, I'll go ahead and answer if I can type before someone closes the question. :) I'm always inclined to treat git repositories as separate units of work or projects. If I'm likely to work on various parts of something as a single project or toward a common goal (e.g., Master's thesis), my tendency would be to treat it as a single repository. And by the way, since the .git repository will be in the root of that single repository, if you need to spin off a piece of your work later and track it separately, you can always create a new repository if needed at that point. Meantime it seems "keep it simple" would mean one repo.

You must manage user_profile yourself. In your user_profile, you can store the user id such as an email address or a google user id like you want. Add a role array in this entity where you store all roles for this user and you manage access with decorators. For example, users which are employers will have "EMPLOYERS" in their roles and you manage access to the job creation handler with a @isEmployer decorator. With this solution, you can assign many roles for you user like "ADMIN" in the future.

Only SkilledPerson may create Resume and JobApplication entities. How do I do this? How do I define these user roles? How do I assign a group of permissions to specific roles?

I'd create a user_profile table which stores their Google user id, and two Boolean fields for is_employer and is_skilled_person, because there's always potential for someone to be both of these roles on your site. (Maybe I'm an employer posting a job but also looking for a job as well) If you perceive having multiple roles and a user can only be one role, I'd make it a string field holding the role name like "employer", "admin", "job seeker" and so on.

python,linux,virtualenv,chroot

bootstrapping a directory tree that can be passed as root That's not what virtualenv does, except (to some degree) for Python packages. It provides a place where these can be installed without replacing the rest of the filesystem. It also works without root privileges and it's portable as it needs no kernel support, unlike chroot, which (I presume) won't work on Windows. Can't one install packages/modules locally in whatever application directory Yes, but virtualenv does one more thing, which is that it disables (by default at least) the system's Python package directories. That means you can test whether your package correctly installs all of its dependencies (you might have forgotten to list one because it's already installed on your system) and it allows installing different versions in case you need either newer or older versions. The ability to install older versions should not be overlooked because sometimes new versions of packages introduce bugs.

First of all let me state that I am a proponent of generic software (in general ;-). I am no expert on Python, but it seems that the 'virtualenv' utility solves pretty much the same problem 'chroot' can help to solve - bootstrapping a directory tree that can be passed as root, thus effectively protecting the real directory tree, if needed. Since I am no expert in Python as already mentioned, I wonder - what problem can virtualenv solve that chroot cannot? I mean, can't I just set up a nice fake root tree (possibly using union mounting), chroot into it, and do pip install a package I want in my new environment, and then play around within the bounds of my new environment, running python scripts and what not? Am I missing something here? Update: Can't one install packages/modules locally in whatever application directory, I mean, without root privileges and subsequently without overwriting or adding files to /usr/lib or /usr/local/lib? It appears that this is what virtualenv does, however I think it has to symlink or otherwise provide a python interpreter for each environment one creates, does it not?

When you launch GUI applications on OS X (.app bundles), no shell is involved and shell profile scripts are not used. IDLE.app is no exception. So any environment variables defined there are not available to the GUI app. The best solution is to properly install your third-party packages into the standard locations included in Python's module search path, viewable as sys.path, and not use PYTHONPATH at all. Another option in this case is to launch IDLE from a terminal session shell, e.g. /usr/local/bin/idle2.7.

I am able to import the OpenCV python bindings (cv2) fine when running Python from the command line, but I receive the standard 'no module named cv2' from IDLE when I import there. I checked the Path Browser in IDLE, and noticed that it doesn't match my .bashrc PYTHONPATH. That said, I copied the cv2 binding files into one of the directories specified in the Path Browser, and IDLE still can't find it. Two questions: 1) Has anyone run into this circumstance? 2) Does IDLE have a PYTHONPATH different from the rest of the system?

python,multithreading,deployment,process,uwsgi

Python's native multithreading is affected by GIL limitations. Simply put, only one Python thread at a time is physically executed. An exception to this are blocking IO calls (e. g. DB query) that let other Python threads take over, which may increase performance of IO-bound operations. So the real performance gain would only be possible if your application is mostly IO-bound. However, in this case you should consider making the app asynchronous, which uWSGI also supports. Otherwise you should keep your app single-threaded and use multiprocess uWSGI to scale up.

You can define the dict with in a module, then import it where ever you wish to refer to it, or you could load it from the datastore, and set the value in the module. You would do this during a warmup request. Defining it in a module, means to alter the contents will require de-deploying the app. Defining it in the datastore, means instances will reload any new definition on startup. You could also set up a handler which could trigger a refresh if reading from the datastore. Defining directly in the datastore means its pickled state needs to be less than 1MB (compressed) if you use a BlobProperty with compressed=True and your using ndb. Other variations similiar to module definition would be to load it from a yaml file etc.. You could define the dict in the app.yaml as an environment variable. There are many options, without knowing the specifics of your use cases it's hard to recommend a particular strategy.

I want to create global scope constant dict, that would be accessed by multiple views. For now I see scenario after deploy: Fetching big file, creating a dict, holding this dict in memory. This process can be re-executed by administrator.

How to check from Linux in Python for administrative access to a Windows machine

I am no sys-admin, but just trying to mount the C-drive ( \hostname\C$ ) via samba/smb should work. This assumes that remote sharing and filesystem access is enabled on that box and the firewall rule setup to allow for remote connections.

I have a network of end-user machines (Windows, Linux, MacOS) and I want to check whether the credential I have allow me to access the machines as administrator (I am checking the "here are the admin credentials to the machines" vs. reality). I wrote a Python script (it runs on Linux) which runs nmap -O on the network to gather the hosts tries to ssh with paramiko to check the Linux credentials. I would like to do a similar check for the Windows machines. What would be a practical way, in Python, to do so? I have a few sets of credentials (AD or local to a machine) so I would need a somehow universal method. I was thinking about something like a call to _winreg.ConnectRegistry but it does not import on my Linux (it does on a Windows box).

I can do it the way I've done it before, which is: Download pyserial from pypi untar pyserial.tgz cd pyserial python3 setup.py install But I'd like to do like the cool kids do, and just do something like pip3 install pyserial. But it's not clear how I get to that point. And just that point. Not interested (unless I have to be) in virtualenv yet.

I know this might seem extreme but if you need 2.6 that badly, try running debian stable in a virtual machine like virtualbox and install 2.6 through that.

I'm using Linux Mint Debian Edition (eq. Debian Testing). There is no python2.6-dev package, which I'd need to install pycrypto for Python 2.6 (since it has a compilation step). Is there any way to get this package or an equivalent on my system? I already have installed Python 2.6 in my system and I can use it without a hitch. (The python2.7-dev package is there just fine. But I'm glued to 2.6, so it doesn't suit my needs.)

I have a Python script I developed within a virtualenv on Windows (Python 2.7). I would now like to compile it into a single EXE using Py2exe. I've read and read the docs and stackoverflow, and yet I can't find a simple answer: How do I do this? I tried just installing py2exe (via the downloadable installer), but of course that doesn't work because it uses the system-level python, which doesn't have the dependencies for my script installed. It needs to use the virtualenv - but there doesn't seem to be such an option. I did manage to get bbfreeze to work, but it outputs a dist folder crammed with files, and I just want a simple EXE file (one file) for my simple script, and I understand Py2Exe can do this. tl;dr: How do I run Py2Exe within the context of a virtualenv so it correctly imports dependencies?

Installing py2exe into your virtual env should be straightforward. You'll need Visual Studio 2008, the express version should work. Launch a 2008 Command Prompt and Activate your virtual env. Change into the directory that contains the py2exe source and run python setup.py install. You can verify that py2exe is in the correct environment by attempting to import it from an interactive shell. I tested myself earlier today (had to install virtualenv). It works exactly as expected.
