If you delete a file which is opened in some processes, it's marked as deleted, but the content remains on disk, so that all processes still can read it. Once all processes close corresponding descriptors (or simply finish), the space will be reclaimed.

I was writing a huge file output.txt (around 10GB) on a server thorugh a python script using the f.write(row) command but because the process was too long I decided to interrupt the program using kill -9 pid The problem is that this space is still used on the server when I check with the command df -h How can I empty the disk occupied by this buffer that was trying to write the file? the file output.txt was empty (0 Byte) when I killed the script, but I still deleted it anyway using rm output.txt but the space in the disk doesn't become free, I still have 10 GB wasted..

PyCharm recognize a module but do not import it

After noticing that the module is already installed, both by pip and by the project interpreter, and nothing worked, this what did the trick (finaly!): make sure the module is indeed installed: sudo pip{2\3} install --upgrade httplib2 locate the module on your computer: find / | grep httplib2 you will need to reach the place in which pip is installing the module, the path would probably look like this: /usr/local/lib/python2.7/dist-packages get into the path specified there, search for the module and copy all the relevant files and folders into your local pycharm project environment. this will be a directory with a path like this: /home/your_user/.virtualenvs/project_name/lib/python2.7 this is it. note however you may need to do this multiple times, since each module may have a dependencies... good luck!

I try to import the PyDrive module in my PyCharm project : from pydrive.auth import GoogleAuth. I tried different things : Installing it directly from the project interpreter Download it with a pip command and import it with the path for the poject interpreter The same thing in Linux Nothing works. Each time PyCharm recognize the module and even sugest the auto-completion, but when I run the project it keeps saying ImportError: No module named pydrive.auth Any suggestion ? EDIT : When I put directly the pydrive folder in my repository, and this time : ImportError: No module named httplib2 from the first import of PyDrive. My path is correct and httplib2 is again in my PyCharm project

You should specify absolute paths to all your files and commands, to be on the safer side. If /home/user/build/tools/caffe train still doesn't work, check if you have a build directory in your caffe root. If not, then use /home/user/tools/caffe train instead.

There are scenarios when I update myprogram.py and need to kill the command, transfer the updated myprogram.py file to the container, and execute python myprogram.py again. I imagine this to be a common scenario. Not really. The common scenario is either: Kill existing container Build new image via your Dockerfile Boot container from new image Or: Start container with a volume mount pointing at your source Restart the container when you update your code Either one works. The second is useful for development, since it has a slightly quicker turnaround.

I have a docker container that is running a command. In the Dockerfile the last line is CMD ["python", "myprogram.py"] . This runs a flask server. There are scenarios when I update myprogram.py and need to kill the command, transfer the updated myprogram.py file to the container, and execute python myprogram.py again. I imagine this to be a common scenario. However, I haven't found a way to do this. Since this is the only command in the Dockerfile...I can't seem to kill it. from the containers terminal when I run ps -aux I can see that python myprogram.py is assigned a PID of 1. But when I try to kill it with kill -9 1 it doesn't seem to work. Is there a workaround to accomplish this? My goal is to be able to change myprogram.py on my host machine, transfer the updated myprogram.py into the container, and execute python myprogram.py again.

It's impossible without modifying either kernel or ps itself. Simple process can't hide itself. But you can change process name by changing argv[0] and mimicry to another common process, like httpd, sshd, etc - that's what a lot of malware does.

Do note that this is not the intended use case of either jupyter or the notebook environment. You should run scripts using your normal python interpreter instead.

Is there a way to define a MongoDB schema using Motor?

No there isn't. Motor is a MongoDB driver, it does basic operations but doesn't provide many conveniences. An Object Document Mapper (ODM) library like MongoTor, built on Motor, provides higher-level features like schema validation. I don't vouch for MongoTor. Proceed with caution. Consider whether you really need an ODM: mongodb's raw data format is close enough to Python types that most applications don't need a layer between their code and the driver.

Quit LLDB session after a defined amount of time

python,ios,lldb

There isn't such a thing built into lldb, but presumably you could set a timer in Python and have it kill the debug session if that's appropriate. Note, when you restart the device, the connection from lldb to the remote debug server should close, and lldb should detect that it closed and quit the process. It won't exit when that happens by default, but presumably whatever you have waiting on debugger events can detect the debuggee's exit and exit or whatever you need it to do. Note, if lldb is waiting on input from debugserver (if the program is running) then it should notice this automatically, since the select call will return with EOF. But if the process is stopped when you close the connection, lldb probably won't notice that till it goes to read something. In the latter case, you should be able to have lldb react to the stop that indicates the "needle" is found, and kill the debug session by hand.

I have a Program written in python for automated testing on mobile devices (iOS & Android). The proper workflow of this program is as follows (for smoke tests): Deploy executable to USB-connected device (.ipa or .app) using ios-deploy Start Application (debugging process) --> writes to stdout. Write output into Pipe --> this way it is possible to read the output of the debugging process parallel to it. If the searched needle is detected in the output, the device is restarted (this is quite a dirty workaround, I am going to insert a force-stop method or something similar) My Problem is: When the needle is detected in the output of the debug process, the lldb session is interrupted, but not exited. To exit the lldb session, I have to reconnect the device or quit terminal and open it again. Is there a possibility to append something like a "time-to-live-flag" to the lldb call to determine how long the lldb session should run until it exits auomatically? Another way I can imagine how to exit the lldb session is to join the session again after the device is restarted and then exit it, but it seems that lldb is just a subprocess of ios-deploy. Therefore I have not found any possibility to get access to the lldb process.

Some confusions regarding celery in python

First, just to explain how it works briefly. You have a celery client running in your code. You call tasks.add(1,2) and a new Celery Task is created. That task is transferred by the Broker to the queue. Yes the queue is persisted in Rabbimq or SQS. The Celery Daemon is always running and is listening for new tasks. When there is a new task in the queue, it starts a new Celery Worker to perform the work. To answer your questions: Celery daemon is always running and it's starting celery workers. Yes Rabitmq or SQS is doing the work of a queue. With the celery monitor you can monitor how many tasks are running, how many are completed, what is the size of the queue, etc.

Then celery adds that task to queue. I am confused if thats 4 or 5 in above list WHen task goes to queue Then worker gets that task and delete from queue The result of that task is saved in Result Backend My Confusions Whats diff between celery daemon and celery worker Is Rabbitmq doing the work of queue. Does it means tasks gets saved in Rabitmq or SQS What does flower do . does it monitor workers or tasks or queues or resulst

I am trying to write an application that uses ZeroMQ to recieve messages from clients. I receive the message from the client in the main loop, and need to send an update to a second socket (general idea is to establish a 'change feed' on objects in the database the application is built on). Receiving the message works fine, and both sockets are connected without issue. However, sending the request on the outbound port simply hangs, and the test server meant to receive the message does not receive anything. Is it possible to use both a REQ and REP socket within the same application? For reference, the main application is C++ and the test server and test client communicating with it are written in Python. They are all running on Ubuntu 14.40. Thanks! Alex

The rsync command is the right out-of-the-box solution to this problem. From the manpage: It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. Rsync is widely used for backups and mirroring and as an improved copy command for everyday use. A simple loop of rsync and sleep will do for you.

How are scheduled Python programs typically ran?

python,scheduled-tasks

The answer to this question will likely depend on your platform, the available facilities and your particular project needs. First let me address system resources. If you want to use the fewest resources, just call time.sleep(NNN), where NNN is the number of seconds until the next instance of 10AM. time.sleep will suspend execution of your program and should consume zero (or virtually zero resources). The python GC may periodically wake up and do maintenance, but it's work should be negligible. If you're on Unix, cron is the typical facility for scheduling future tasks. It implements a fairly efficient Franta–Maly event list manager. It will determine based on the list of tasks which will occurr next and sleep until then. On Windows, you have the Schedule Manager. It's a Frankenstein of complexity -- but it's incredibly flexible and can handle running missed events due to power outages and laptop hibernates, etc...

If you are writing the output to the same file in disk, then yes, it will be overwritten. However, it seems that you're actually printing to the stdout and then redirect it to a file. So that is not the case here. Now answer to your question is simple: there is no interaction between two different executions of the same code. When you execute a program or a script OS will load the code to the memory and execute it and subsequent changes to code has nothing to do with the code that is already running. Technically a program that is running is called a process. Also when you run a code on two different terminals there will be two different processes on the OS one for each of them and there is no way for two process to interfere unless you explicitly do that (IPC or inter-process communication) which you are doing here. So in summary you can run your code simultaneously on different terminals they will be completely independent.

Each Python interpreter process is independent. How the script reacts to itself being run multiple times depends on the exact code in use, but in general they should not interfere.

Check the .git/FETCH_HEAD for the time stamp and the content. Every time you fetch content its updating the content and the modification time of the file.

TL;DR I would like to be able to check if a git repo (located on a shared network) was updated without using a git command. I was thinking checking one of the files located in the .git folder to do so, but I can't find the best file to check. Anyone have a suggestion on how to achieve this? Why: The reason why I need to do this is because I have many git repos located on a shared drive. From a python application I built, I synchronize the content of some of these git repo on a local drive on a lot of workstation and render nodes. I don't want to use git because the git server is not powerful enough to support the amount of requests of all the computers in the studio would need to perform constantly. This is why I ended up with the solution of putting the repos on the network server and syncing the repo content on a local cache on each computer using rsync That works fine, but the as time goes by, the repos are getting larger and the rsync is taking too much time to perform. So I would like to be have to (ideally) check one file that would tell me if the local copy is out of sync with the network copy and perform the rsync only when they are out of sync. Thanks

I have a BLE device which has a bunch of GATT services running on it. My goal is to access and read data from the service characteristics on this device from a Linux computer (BlueZ version is 5.37). I have enabled experimental mode - therefore, full GATT support should be available. BlueZ's DBUS API, however, only provides the org.bluez.GattManager1 interface for the connected device, and not the org.bluez.GattCharacteristic1 or org.bluez.GattService1 interfaces which I need. Is there something I'm doing wrong? The device is connected and paired, and really I've just run out of ideas as how to make this work, or what may be wrong. If it helps, I'm using Python and the DBUS module to interface with BlueZ.

U need a compiler to build the cryptography module, and it is not included. The best option is to get the cross compiler then build the module yourself. I don't see any prebuilt module for QPython about ssh/paramiko. Maybe u can try out other libs, busybox/ssh or maybe dropbear for arm. Update I've take a proper look at the QPython modules, and both OpenSSL and SSH are preinstalled. You don't need to install them. Still having problem with the Crypto module. I can't understand how much usefull is the ssh module without the Cryto one ... omg. Update 2 Tried the Qpypi lib manager, found the cryptography on list, but at time of install didn't found it. Couldn't believe how much difficult is to put ssh to work with QPython.

How to determine the cause for "BUS-Error"

37,817,521

9

17,329

0

python,linux,embedded

Bus errors are generally caused by applications trying to access memory that hardware cannot physically address. In your case there is a segmentation fault which may cause dereferencing a bad pointer or something similar which leads to accessing a memory address which physically is not addressable. I'd start by root causing the segmentation fault first as the bus error is the secondary symptom.

I'm working on a variscite board with a yocto distribution and python 2.7.3. I get sometimes a Bus error message from the python interpreter. My program runs normally at least some hours or days before the error ocours. But when I get it once, I get it directly when I try to restart my program. I have to reboot before the system works again. My program uses only a serial port, a bit usb communication and some tcp sockets. I can switch to another hardware and get the same problems. I also used the python selftest with python -c "from test import testall" And I get errors for these two tests test_getattr (test.test_builtin.BuiltinTest) ... ERROR test_nameprep (test.test_codecs.NameprepTest) ... ERROR And the selftest stops always at test_callback_register_double (ctypes.test.test_callbacks.SampleCallbacksTestCase) ... Segmentation fault But when the systems runs some hours the selftests stops earlier at ctypes.macholib.dyld Bus error I checked the RAM with memtester, it seems to be okay. How I can find the cause for the problems?

The settings for the 'Actions' tab are as follows: Action: Start a Program Program/script: C:\<path to script>.py Add arguments: Start in: C:\<directory of script> I can run the python files just fine if I use the command line and navigate to the file location and use python or even just using python without navigating. For some reason, the scripts just won't run with a scheduled task. I've checked all over and tried various things like making sure the user profile is set correctly and has all of the necessary privileges, which holds true. These scripts have been working for several weeks now with no problems, so something has changed that we aren't able to identify at this time. Any suggestions?

How do I get a pip shim in ~/.pyenv/shims. I am using pyenv, but which pip still shows the system version of pip. Based on the below comment copied from the docs, it appears it should occur through rehashing, but I have run pyenv rehash and nothing happen happens Copied from docs: Through a process called rehashing, pyenv maintains shims in that directory to match every Python command across every installed version of Python—python, pip, and so on. Per request in comments here is my PATH /Users/patrick/google-cloud-sdk/bin:/Users/patrick/.pyenv/shims:/Users/patrick/.pyenv/bin:/Users/patrick/.local/bin:/Users/patrick/npm/bin:/Users/patrick/google_appengine:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/mongodb/bin and here is my ~/.pyenv/shims content: $ ll ~/.pyenv/shims/ total 80 drwxr-xr-x 12 patrick staff 408 May 23 09:49 . drwxr-xr-x 22 patrick staff 748 May 4 18:10 .. -rwxr-xr-x 1 patrick staff 408 May 4 18:15 2to3 -rwxr-xr-x 1 patrick staff 408 May 4 18:15 idle -rwxr-xr-x 1 patrick staff 408 May 4 18:15 pydoc -rwxr-xr-x 1 patrick staff 408 May 4 18:15 python -rwxr-xr-x 1 patrick staff 408 May 4 18:15 python-config -rwxr-xr-x 1 patrick staff 408 May 4 18:15 python2 -rwxr-xr-x 1 patrick staff 408 May 4 18:15 python2-config -rwxr-xr-x 1 patrick staff 408 May 4 18:15 python2.7 -rwxr-xr-x 1 patrick staff 408 May 4 18:15 python2.7-config -rwxr-xr-x 1 patrick staff 408 May 4 18:15 smtpd.py

Did you restart the Spark workers with the new setting? Changing the environment setting just for your driver process is not enough: tasks created by the driver will cross process, sometimes system, boundaries to be executed. Those tasks are compiled bits of code, so that is why both versions need to match.

Yes, this is the expected behaviour, each deployment is standalone, no assumption is made about anything being "already deployed", all app's artifacts are uploaded at every deployment. Update: Kekito's comment suggests different tools may actually behave differently. My answer applies to the linux version of the Python SDK, regardless of deploying a new version or re-deploying the same version.

After i recently updated the gcloud components with gcloud components update to version 108.0.0, i noticed the gcloud preview app deploy app.yaml command has started taking too long every time (about 15 minutes) for my project. Before this it only used to take about a minute to complete. I figured out that using gcloud preview app deploy --verbosity info app.yaml displays progress of deployment process and I noticed every file in source code is being uploaded every time i deploy including the files in lib directory which has a number of packages installed, about 2000 files in it so this is where the delay is coming from. Since I am new to appengine, i dont know if this is normal. The project exists inside a folder of git repo, and i noticed after every deploy, 2 files in default directory, source-context.json and source-contexts.json, are being created and have information about git repo inside. I feel that can somehow be relevant. I went through a number of relevant questions here but couldnt figure out the issue. It would be great if this can be resolved if its an issue at all because its a big inconvenience having to wait 15 mins to deploy every time. I only started using google appengine a month ago so please dont mind if the question is incorrect. Please let me know if additional info is needed to resolve this. Thanks UPDATE: I am using gcloud sdk on ubuntu 14.04 LTS.

Since you're on windows, you probably just don't have pg_restore on your path. You can find pg_restore in the bin of your postgresql installation e.g. c:\program files\PostgreSQL\9.5\bin. You can navigate to the correct location or simply add the location to your path so you won't need to navigate always.

Python script to detect USBs in java GUI

37,133,845

java,python,javafx,automation,libusb

No, in most (Windows) scenarios this will not work. The problem is that libusb on Windows uses a special backend (libusb0.sys, libusbK.sys or winusb.sys). You have to install one of those backends (libusb-win32 is libusb0.sys) on every machine you want your software to run on. Under Linux this should work fine out of the box. Essentially you have to ship the files you generate with inf_wizard.exe with your software and install the inf (needs elevated privileges) before you can use the device with your software.

I'm making a java GUI application (javafx) that calls a python script (python2.7) which detects connected devices. The reason for this is so I can automate my connections with multiple devices. In my python script, I use pyusb. However to detect a device, I have to use inf_wizard.exe from libusb-win32 to communicate with the device. This is fine for my own development and debugging, but what happens if I wish to deploy this app and have other users use this? Would this app, on another computer, be able to detect a device? Thanks Please let me know if there is a better way to doing this.

This could not find a repository. The install does work however if I do sudo apt-get install python-opencv this issue with this is that by not adding the three to python it installs for python 2 which I do not use. I would really perfer not to have to build and install from source so is there a way I can get a repository? I also tried installing it with pip3 and it could not find it either.

I know I'm jumping in a little late, but my installations seem to all reside away from /usr/local/bin/... . What worked for me was adding an export path in bash_profile for my django installation. This also made me realize that it was installed globally. From what I've heard, it's better to install django locally within venv as you work on different projects. That way each virtual environment can contain its own versions and dependencies for django (and whatever else you're using). Big thanks to @Arefe.

I solved the issue after reading a webpage about the mentioned issue. In the Python shell, write the following, >> import django >> django.__file__ >> django also works It will provide the installation location of django. Change the path to the new path /usr/local/bin/django-admin.py, sudo ln -s the complete path of django-admin.py /usr/local/bin/django-admin.py In Mac OS, The call needs to be django-admin.py startproject mysite than django-admin startproject mysite

App engine vs Compute engine : django project

DigitalOcean is IaaS (infrastructure as a service). I guess the corresponding offer from Google is Google Compute Engine, GCE. Google App Engine is more like Heroku, a PaaS offer (platform as a service). In practice, what is the difference between PaaS and IaaS? IaaS: if you have a competent system administrator in your team he probably will choose IaaS - because this kind of service will give him more control at the cost of more decisions and setup - but that is his work. PaaS: if you are willing to pay more (like double it) to avoid most of the management work and don't mind a more opinionated platform, than a PaaS may be the right product for you. You are a programmer and just want to deploy your code (and you are happy to pay an extra in order to avoid dealing with those dickheads in operations). Probably you can find a more elegant comparison if you google for it.

I've deployed code changes to a GAE app under development and broken the app. My IDE isn't tracking history to the point in time where things still worked, and I didn't commit my code to a repo as often as I updated the app, so I can't be sure what the state of the deployed code was at the point in time when it was working, though I do know a date when it was working. Is there a way to either: Rollback the app to a specific date? See what code was deployed at a specific deployment or date? I see that deployments are logged - I'm hoping that GAE keeps a copy of code for each deployment allowing me to at least see the code or diffs.

You can not generate Windows executable files on OS X. You must use the platform which you want the program to run on to compile the program. If you own a copy of Windows, you could run a virtual machine on you Mac and compile it on that.

I had the same issue. Internal or External command can be solved but just 3 steps: (Before doing make sure you undo all hidden apps) Select the path of the scripts which are there in your local computer (eg. C drive--> users --> (a file with your name) --> AppData --> Local --> then while you go forward you find Scripts. Copy that Path. Open edit the system environment variables--> go to path --> add new --> paste the copied Scripts path and click ok. Close all the prompts and run again. It worked for me

As far as my experiments for jenkins and python goes, shining panda plug-in doesn't install python in slave machines in fact it uses the existing python library set in the jenkins configuration to run python commands. In order to install python on slaves, I would recommend to use python virtual environment which comes along with shining panda and allows to run the python commands and then close the virtual environment.

The Jenkins ShiningPanda plugin provides a Managers Jenkins - Configure System setting for Python installations... which includes the ability to Install automatically. This should allow me to automatically setup Python on my slaves. But I'm having trouble figuring out how to use it. When I use the Add Installer drop down it gives me the ability to Extract .zip/.tar.gz Run Batch Command Run Shell Command But I can't figure out how people us these options to install Python. Especially as I need to install Python on Windows, Mac, & Linux. Other Plugins like Ant provide an Ant installations... which installs Ant automatically. Is this possible with Python?

When I open a terminal on JupyterHub and try to run commands that I've placed in the machine's path, it says "command not found." The default PATH variable on Jupyterhub terminal seems to be /sbin:/usr/sbin:/bin:/usr/bin:/usr/local/bin and I'm wondering why it doesn't use the PATH as defined on the machine. Is there a way to get it to inherit this PATH, or to run some command like source /etc/environment whenever a terminal is generated?

reason for subprocess startup error can be a new python file that you have created recently with the same name as same existing libraries or module name e.g. 're.py','os.py' etc beacuse re,os are the predefined libraries just go and find the file and rename it hope so it will be resolved

I have just installed kivy in python 2.7.11. After installing it, whenever i try to open IDLE, it is giving subprocess startup error. Actually i installed kivy on my windows 7 PC through command prompt. After installation, I copied programs of kivy from my android tab to run them on my pc. When I tried to open them, IDLE doesn't respond for some time and after some time it gives startup error. Since then IDLE is not starting . But it is quite strange that, on running python builtin module, there is no error. I had reinstalled python but still there is no change.

I need to redirect my clients to another endpoint in my django app. I know I can use relative urls with request.build_absolute_uri() to do this, but I am searching for a generic solution that doesn't require the redirecting handler to know its own place in the URL hierarchy. As an example, I have handlers at the following two URLs: https://example.com/some/other/namespace/MY_APP/endpoint_one https://example.com/some/other/namespace/MY_APP/foo/bar/endpoint_two Both handlers need to redirect to this URL: https://example.com/some/other/namespace/MY_APP/baz/destination_endpoint I would like for endpoint_one and endpoint_two to both be able to use the exact same logic to redirect to destination_endpoint. My app has no knowledge of the /some/other/namespaces/ part of the URL, and that part of the URL can change depending on the deployment (or might not be there at all in a development environment). I know I could use different relative urls from each endpoint, and redirect to the destination URL. However, that required that the handlers for endpoint_one and endpoint_two know their relative position in the URL hierarchy, which is something I am trying to avoid.

asyncio logging for cluster app

python-3.x,logging,cluster-computing

A simple solution is to ask for logging to log on syslog (typically /dev/log, which won't block your application), locally (so your application is not bound to your logging system: it's still portable), then let rsyslog (I prefer syslogng personally) transmit them to a main log server. Another solution is to use a tool like logstash to push your logs to an elasticsearch server / cluster so you can browse and graph them easily. In this case, if your log lines are json objects, it's a big win because elasticsearch-side (typically via kibana), you'll be able to query, filter, and aggregate on fields of your json documents. Typically graphing info vs warnings vs errors, frequency of errors per file, or per user, etc...

Need advice on the organization of logging in a clustered application written in Python(asyncio). Applications use the logging module and store logs local file. See the logs with 3 servers uncomfortable. I would like to use rsyslog, but there are fears that it will block the application. Another way to use aioredis(push to channel) and another application to collect data in a single file.

Based on your description, I would suggest that you have your project built using stock autotools-generated configure and Makefile, i.e. autoconf and automake, and have either your configure or your Makefile take care of executing your setup.py, in order to set up your Python bits. I have a project that's mostly C/C++ code, together with a Perl module. This is very similar to what you're trying to do, except that it's Perl instead of Python. In my Makefile (generated from Makefile.am) I have a target that executes the Perl module's Makefile.PL, which is analogous to Python's setup.py, and in that manner I build the Perl module together with the rest of the C++ code, seamlessly together, as a single build. Works fairly well. automake's Makefile.am is very open-ended and flexible, and can be easily adapted and extended to incorporate foreign bits, like these.

I'm working on transitioning a project from scons to autotools, since I it seems to automatically generate a lot of features that are annoying to write in a SConscript (e.g. make uninstall). The project is mostly c++ based, but also includes some modules that have been written in python. After a lot of reading autotools, I can finally create a shared library, compile and link an executable against it, and install c++ header files. Lovely. Now comes they python part. By including AM_PYTHON_PATH in configure.ac, I'm also installing the python modules with Makefile.am files such as autopy_PYTHON=autopy/__init__.py autopy/noindent.py autopy/auto.py submoda_PYTHON=autopy/submoda/moda.py autopy/submoda/modb.py autopy/submoda/modc.py autopy/submoda/__init__.py submodb_PYTHON=autopy/submodb/moda.py autopy/submodb/modb.py autopy/submodb/modc.py autopy/submodb/__init__.py autopydir=$(pythondir)/autopy submodadir=$(pythondir)/submoda submodbdir=$(pythondir)/submodb dist_bin_SCRIPTS=scripts/script1 scripts/script2 scripts/script3 This seems to place all my modules and scripts in the appropriate locations, but I wonder if this is "correct", because the way to install python modules seems to be through a setup.py script via distutils. I do have setup.py scripts inside the python modules and scons was invoking them until I marched in with autotools. Is one method preferred over the other? Should I still be using setup.py when I build with autotools? I'd like to understand how people usually resolve builds with c++ and python modules using autotools. I've got plenty of other autotools questions, but I'll save those for later.

I'll start by saying I am a complete novice and am likely overlooking something obvious. Don't assume I have any idea about anything related to linux or python. Anyway, I installed python 3.5 onto my computer which runs Fedora 23. Fedora comes prepackaged with 2.7. When I installed 3.5, I somehow installed it into my /home/user/Documents directory. I since deleted that rm -r -f /home/user/Documents/Python-3.5.1 directory. Yet I can still open 3.5 when I type python3. Originally I created an alias to point to the python command in the home/user/Documents/Python-3.5.1 directory, so being able to still open 3.5 after deleting that directory and removing the alias is confusing, and must mean I had two python 3.5 installs. That's some backstory that isn't really my problem, but maybe it's related. The issue I'm having is that I cannot install a module that I want to import for use in a Python 3.5 program. When I type pip install pyperclip (I'm working through AutomateTheBoringStuff) pyperclip is installed for 2.7. If I open the python2.7 command line and type import pyperclip everything is fine, but if I try the same thing in the python3.5 command line I get an error saying the module does not exist. I assume this is because pip installs the pyperclip module to the subdirectories associated with 2.7. How can I install modules for 3.5 using pip?

Correct architectual way to send "datagrams" via TCP

python,sockets,tcp,packet,datagram

Since TCP is only an octet stream this is not possible without glue, either around your data (i.e. framing) or inside your data (structure with clear end). The way this is typically done is either by having a delimiter (like \r\n\r\n between HTTP header and body) or just prefix your message with the size. In the latter case just read the size (fixed number of bytes) and then read this number of bytes for the actual message.

I need to transmit full byte packets in my custom format via TCP. But if I understand correctly TCP is streaming protocol, so when I will call send method on sender side, there is not guaranty that it will be received with same size on receiver side when call recv (It can be merged together with Nagle's algorithm and then splited when will not fit into frame or when not fit to buffer). UDP provides full datagrams so there is no such issue. So question is: what will be the best and correct way to recv same pacakges as it was send, with same size, with no glue. I develop using python. I think I can use something like HDLC but I am not sure that iterating throug each byte will be best choice. Maybe there are some open-source small examples for this situation or it is discribed in books?

periodic tasks scheduler in celery is not designed to handle thousands of scheduled tasks, so from performance perspective, much better solution is to have one task that is running at the smallest interval (e.g. if you allow user to sechedule dayly, weekly, monthly - running task daily is enough) such approach is as well more stable - every time schedule changes, all of the schedule records are reloaded plus is more secure because you do not expose or use any internal mechanisms for tasks execution

I'm working on project which main future will be running periodically one type of async task for each user. Every user will be able to configure task (running daily, weekly etc. at specified time). Also task will use some data stored by user. Now I'm wondering which approach should be better: allow users to create own PeriodicTask (by using some restricted endpoint of course) or create single PeriodicTask (for example running every 5 minutes) which will iterate over all users and determine if task should be queued or not for current user? I think I will use AMPQ as broker.

Subprocess Hanging on Wait

The second command will not hang because the issue is not with a large amount of data on standard output, but a large amount of data on standard error. In the former case, standard error is being redirected to standard output, which is being piped to your program. Hence, a large amount of data being produced on standard error gives an equivalent result to a large amount of data being produced on standard output. In the latter case, the subprocess's standard error is redirected to the calling process's standard error, and hence can't get stuck in the pipe.

From the documentation of Popen.wait(), I see Warning This will deadlock when using stdout=PIPE and/or stderr=PIPE and the child process generates enough output to a pipe such that it blocks waiting for the OS pipe buffer to accept more data. Use communicate() to avoid that. I am having a bit of trouble understanding the behavior below as the command run below can generate a fairly large amount of standard out. However, what I notice is that subproc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) will hang. While subproc = subprocess.Popen(command, stdout=subprocess.PIPE) will not hang. If the command is generating a large amount of standard out, why does the second statement not hang as we are still using stdout=subprocess.PIPE?

I'm using with open('myFile', 'rb') as file: to read a file. When running the program with python myProgram.py everything works fine. But as soon I try to run it without cd-ing into the directory of myProgram.py and use an absolute path instead (like python /home/myName/myCode/myProgram.py I always get this error message: FileNotFoundError: [Errno 2] No such file or directory. So why does open() behave differently depending on how the Python program is started? And is there a way to make things work even if starting with an absolute path? I've already tried open('/home/myName/myCode/myfile', 'rb') but without success...

Trap sigint, sigterm and make sure to clean up anything like sockets, files, locks, etc. Trap other signals based on what you are doing. For instance if you have open pipes you might trap sigpipe. Just remember signal handling opens you to race conditions. You probably want to use sigprocmask to disable signals while handling them.

I'm creating a program in python that auto-runs for an embedded system and want to handle program interruptions gracefully. That is if possible close resources and signal child processes to also exit gracefully before actually exiting. At which point my watchdog should notice this and respawn everything. What signals can/should I expect to receive in a non-interactive program from linux? I'm using try/except blocks to handle i/o errors. Is the system shutting down an event that is signaled? In addition to my watchdog I will also have an independent process monitoring a hardware line that gets set when my power supply detects a brownout. I have a supercap to provide some run-time to allow a proper shutdown.

We had same issue where we had to share sensor data between one Java app to other multiple apps including Java,Python and R. First we tried Socket connections but socket communication were not fault tolerant. Restarting or failure in one app affected other. Then we tried RMI calls between them but again we were unhappy due to scalability. We wanted system to be reliable, scalable, distributed and fault tolerant. So, finally we started using RabbitMQ where we created one producer and multiple consumers. It worked well for 2 years. you may consider using Apache Kafka. You have options like Socket pipes, RMI calls, RabbitMQ, Kafka, Redis based on your system requirements now and in near future.

I'm working on a project, which I am not at liberty to discuss the core, but I have reached a stumbling block. I need data to be transferred from C++ to some other language, preferably Java or Python, in realtime (~10ms latency). We have a sensor that HAS to be parsed in C++. We are planning on doing a data read/output through bluetooth, most likely Java or C# (I don't quite know C#, but it seems similar to Java). C++ will not fit the bill, since I do not feel advanced enough to use it for what we need. The sensor parsing is already finished. The data transferring will be happening on the same machine. Here are the methods I've pondered: We tried using MatLab with whatever the Mex stuff is (I don't do MatLab) to access functions from our C++ program, to retrieve the data as an array. Matlab will be too slow (we read somewhere that the TX/RX will be limited to 1-20 Hz.) Writing the data to a text, or other equivalent raw data, file constantly, and opening it with the other language as necessary. I attempted to look this up, but nothing of use showed in the results.

Running the above launches Foo.py in a new terminal window, and allows the user to terminate the Foo.py process if desired.

I am writing a bootstrap program that runs several individual programs simultaneously. Thus, I require each sub-program to have its own terminal window, in a manner that gives me the ability to start/stop each sub-program individually within the bootstrap. I was able to do this on Windows using Popen and CREATE_NEW_CONSOLE (each sub-program has it's own .py file), however I am having trouble achieving this with Linux. I am using a Raspberry Pi and Python 2.7.9. I have tried: Subprogram = Popen([executable, 'Foo.py'], shell=True) However this does not seem to create a new window.. and os.system("python ./Foo.py") Does not seem to create a new window nor allow me to terminate the process. Other research has thus far proved unfruitful.. How can I do this? Many thanks in advance.

Attribute system similar to HTTP Headers for local files

python,file-io,go,attributes,metadata

If you are dealing with binary files like docx and pdf, you're best off storing the metadata in seperate files or in a sqlite file. Metadata is usually stored seperate from files, in data structures called inodes (at least in Unix systems, Windows probably has something similar). But you probably don't want to get that deep into the rabbit hole. If your goal is to query the system based on metadata, then it would be easier and more efficient to use something SQLite. Having the meta data in the file would mean that you would need to open the file, read it into memory from disk, and then check the meta data - i.e slower queries. If you don't need to query based on metadata, then storing metadata in the file might make sense. It would reduce the dependencies in your application, but in order to access the contents of the file through Word or Adobe Reader, you'd need to strip the metadata before handing it off to the application. Not worth the hassle, usually

I am in the process of writing a program and need some guidance. Essentially, I am trying to determine if a file has some marker or flag attached to it. Sort of like the attributes for a HTTP Header. If such a marker exists, that file will be manipulated in some way (moved to another directory). My question is: Where exactly should I be storing this flag/marker? Do files have a system similar to HTTP Headers? I don't want to access or manipulate the contents of the file, just some kind of property of the file that can be edited without corrupting the actual file--and it must be rather universal among file types as my potential domain of file types is unbound. I have some experience with Web APIs so I am familiar with HTTP Headers and json. Does any similar system exist for local files in windows? I am especially interested in anyone who has professional/industry knowledge of common techniques that programmers use when trying to store 'meta data' in files in order to access them later. Or if anyone knows of where to point me, as I am unsure to what I should be researching. For the record, I am going to write a program for Windows probably using Golang or Python. And the files I am going to manipulate will be potentially all common ones (.docx, .txt, .pdf, etc.)

No, it is not currently possible to test this in Tornado via any public interface (as of Tornado version 4.3). It's straightforward to avoid spinning up a server, although it requires a nontrivial amount of code: the interface between HTTPServer and Application is well-defined and documented. The trickier part is the other side: there is no supported way to determine which handler will be invoked before that handler is invoked. I generally recommend testing routing via end-to-end tests for this reason. You could also store your URL route list before passing it into Tornado, and do your tests against that - the internal logic of "take the first regex match" is pretty easy to replicate.

I'd prefer to use pytest as my testing framework, but I'm not sure it matters. Is there a way to, say, create my project's instance of tornado.web.Application, and pass it arbitrary paths and assert which RequestHandler will be invoked based on that path?

The space in the name of your disk ("HD 2") is tripping things up. The path to the Python interpreter (which is going to be /Volumes/HD 2/Projects/PythonProjects/BV/bin/python) is getting split on the space, and the system is trying to execute /Volumes/HD. You'd think that in 2016 your operating system ought to be able to deal with this. But it can't, so you need to work around it: Rename "HD 2" to something that doesn't contain a space. Re-create the virtualenv.

I think you should use communicate. The message warns you about performance issues with the default behaviour of the method. In fact, there's a buffer size parameter to the popen constructor that can be tuned to improve a lot performance for large data size. I hope it will help :)

I am trying to run a subprocess in Python 3 and constantly read the output. In the documentation for subprocess in Python 3 I see the following: Popen.wait(timeout=None) Wait for child process to terminate. Set and return returncode attribute. Warning This will deadlock when using stdout=PIPE and/or stderr=PIPE and the child process generates enough output to a pipe such that it blocks waiting for the OS pipe buffer to accept more data. Use communicate() to avoid that. Which makes me think I should use communicate as the amount of data from stdout is quite large. However, reading the documentation again shows this: Popen.communicate(input=None, timeout=None)... Interact with process: Send data to stdin. Read data from stdout and stderr, until end-of-file is reached. Note The data read is buffered in memory, so do not use this method if the data size is large or unlimited. So again, it seems like there are problems with reading starndard out from subprocesses this way. Can someone please tell me the best / safest way to run a subprocess and read all of its (potentially large amount) of stdout?

My question is: will programs, that depends from python command and expects python2, work correctly? Those programs should use full path of the python binary. Something like /usr/bin/python, and so $PATH is irrelevant. As long as you don't change /usr/bin/python, nothing will break. If you remove the stuff that Anaconda has added, it's likely that Anaconda will not work properly.

Strictly speaking, Google Cloud Datastore is distributed multi-dimensional sorted map. As you mentioned it is based on Google BigTable, however, it is only a foundation. From high level point of view Datastore actually consists of three layers. BigTable This is a necessary base for Datastore. Maps row key, column key and timestamp (three-dimensional mapping) to an array of bytes. Data is stored in lexicographic order by row key. High scalability and availability Strong consistency for single row Eventual consistency for multi-row level Megastore This layer adds transactions on top of the BigTable. Datastore A layer above Megastore. Enables to run queries as index scans on BigTable. Here index is not used for performance improvement but is required for queries to return results. Furthermore, it optionally adds strong consistency for multi-row level via ancestor queries. Such queries force the respective indexes to update before executing actual scan.

The fact that names reserved by the Python API are enforced in the API, but not in the Datastore itself makes me question the extent Datastore mirrors the internal workings of BigTable. For example, validation features in the ndb.Model class are enforced in the application code but not the datastore. An entity saved using the ndb.Model class can be retrieved someplace else in the app that doesn't use the Model class, modified, properties added, and then saved to datastore without raising an error until loaded into a new instance of the Model class. With that said, is it safe to say Google Cloud Datastore is a Column Oriented NoSQL database? If not, then what is it?

Gevent's libev, and Twisted's reactor

Short answer: Twisted is a network framework. Gevent tries to act as a library without requiring from the programmer to change the way he programs. That's their focus.. and not so much how that is achieved under the hood. Long answer: All asyncio libraries (Gevent, Asyncio, etc.) work pretty much the same: Have a main loop running endlessly on a single thread. When an event occurs, it's captured by the main loop. The main loop decides based on different rules (scheduling) if it should continue checking for events or switch temporarily and give control to any subscriber functions to the event. greenlet is a different library. It's very simple in that it just changes the order that Python code is run and lets you change jumping back and forth between functions. Gevent uses it under the hood to implement its async features. asyncio which comes with Python3 is like gevent. The big difference is the interface again. It requires the programmer to mark functions with async and allow him to explicitly wait for a subscribed function in the main loop with await. Gevent is like asyncio. But instead of the keywords it patches existing code where appropriate. It uses greenlet under the hood to switch between main loop and subscribed functions and make it all work seamlessly. Twisted as mentioned feels more like a framework than a library. It requires the programmer to follow very specific ways to achieve concurrency. Again though it has a main loop under the hood called reactor like everything else. Back to your initial question: You can in theory replace the reactor with any loop (including gevent). But that would defeat the purpose. Probably Twisted's team decided to use their own version of a main loop for optimisation reasons. All these libraries use different scheduling in their main loops to meet their needs.

I'm trying to figure out how Gevent works with respect to other asynchronous frameworks in python, like Twisted. The key difference between Gevent and Twisted is that Gevent uses greenlets and monkey patching the standard library for an implicit behavior and a synchronous programming model whereas Twisted requires specific libraries and callbacks for an explicit behavior. The event loop in Gevent is libev/libevent, which is written in C, and the event loop in Twisted is the reactor, which is written in python. Is there anything special about libev/libevent that allows for this implicit behavior? Why not use an event loop written in Python? Conversely, why isn't Twisted using libev/libevent? Is there any particular reason? Maybe it was simply a design choice and could have gone either way... Theoretically, can Gevent's libev be replaced with another event loop, written in python, like Twisted's reactor? And can Twisted's reactor be replaced with libev?

Determine if a python program is running on WINE

First of all, and this is untested, try creating a symlink from .wine/dosdevices/COM1 to /dev/ttyS0. It should simply allow you to open the com port the Windows way. If, however, you are determined to know whether you are running on Wine, the "official" way is to check whether the registry has the key "HKEY_LOCAL_MACHINE\Software\Wine". Either way, if opening COM1 doesn't work on Wine, it is a bug and should be filed with the Wine bugzilla.

I can check for Linux/Windows/cygwin/etc. with sys.platform, but on WINE it just reports 'win32'. I am attempting to write a multi-platform application that uses pyserial, and I am using WINE to test setup of a Windows environment. On Windows serial ports are named COMxx, but on Linux they are /dev/ttyxxx. However, on WINE the serial ports have Linux names. I need to detect if it is running on WINE separate from Windows so I can handle this properly.

How to handle google api oauth in this app?

python,google-oauth

You can create a server-side script in which you use Google OAuth to upload videos to A's account. Then you can create a client-side app which allows your clients B and C to upload their videos to the server; on completion, the server can then upload them to A's account. Alternatively, to avoid uploading twice, if you trust the clients and would like them to be able to upload directly, you can pass them an OAuth access token to A's account.

My client asked me to build a tool that would let him and his partners to upload video to youtube to his channel automatically . For example let's say that my client is A and he has some buisness partners . A want to be able to upload videos to his channel, that is easy to do, but the problem here is to let other parners B and C to upload their videos to His channel (channel of the person of A) . In this case I would need "A" to auth my app so he can upload videos to his own channel, but how can I handle that for other users . How can users use the access token of the person "A" to upload videos to his channel ? What I've done so far ? I've got the youtube upload python sample from google api docs and played with it a bit. I tried to subprocess.Popen(cmd) where cmd is the following command : python upload.py --file "video name" --title "title of the vid" . This will lead the user to auth my app once , that's only fine for the "A" person .The others won't be able to do that, since they need to upload the vid to A's account .

Multiple threads inside docker container

A container as such has nothing to do with the computation you need to perform. The question you are posting is whether I should have multiple processes doing my processing or multiple threads spawned by the same process doing the processing ? A container is just a platform for running your application in the environment you want. Period. It means, you would be running a process inside a container to run your business logic. Multiple containers simply means multiple processes and as it is advised, you should go for multiple threads rather than multiple processes as spawning a new process (in your case, as container) would eat up more resources and would also require more memory etc. So it is better to have just one container which will spawn multiple threads to do the job for you. However, it also depends upon the configuration of the underlying machine on which the container is started. If it makes sense to spawn multiple containers with multiple threads because of the multicore capabilities of the underlying hardware, you should do that as well.

I need to spawn N threads inside a docker container. I am going to receive a list of elements, then divide it in chunks and each thread will process each chunk. So I am using a docker container with one process and N threads. Is it good practice in docker? I think so, because we have, e.g, apacha webserver that handle connections spawining threads. Or it will be better to spawn N container each one for each chunk? If it is, what is the correct way to do this?

I try to use virtualenv inside a folder using the command virtualenv . and getting the error -bash: virtualenv: command not found. However, I installed virtualenv using pip pip installed virtualenv and also, upgraded it earlier with sudo pip install virtualenv. How to use virtualenv properly ? I'm following a tutorial and they seems doing the same and gets away with it. I'm a Java developer with beginner knowledge of Python and working to improve it.

My Eclipse stalled so I shut it down (normally, I didn't send any kill signal or anything, the editor was bugging but the menu was still working so I simply quit it from the menu). When I reopened eclipse however I got the problem: Plug-in org.python.pydev was unable to load class org.python.pydev.editor.PyEdit. I am using Eclipse Kepler Release 2 Build id: 20140224-0627 with Java 8 and PyDev 4.5.4.20160129223 I have tried rebuilding the workspace, cleaning the workspace, restarting it, but nothing works. I have now updated PyDev to PyDev 5 and it still gives me the same error. Additionally, the Package Explorer can't load either and gives the error: Plug-in org.eclipse.jdt.ui was unable to load class org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart. Any ideas? The exact traceback is: org.eclipse.core.runtime.CoreException: Plug-in org.python.pydev was unable to load class org.python.pydev.editor.PyEdit. at

Alright, this isn't the most reliable solution but it does seem to work. To start with you must verify you have pulseaudio installed and working Use what ever package installer you need: apt-get/yum/zypper pulseaudio pulseaudio-devel alsa-lib alsa-devel alsa-plugins-pulseaudio pulseaudio --start pacmd load-module module-null-sink sink_name=MySink pacmd update-sink-proplist MySink device.description=MySink This will allow you to pass audio around in your vm so that it can be sent out using pjsip. If you dont have your own loopback written in python you can use: pacmd load-module module-loopback sink=MySink to pass audio back out. If you do have a loopback written you cannot use both.

I am writing a SIP client in python. I am able to make my script run on my computer just fine. It plays a wav file, grabs the audio and then sends the audio out using a sip session. I am having a very hard time getting this to run in the AWS ec2 VM. The VM is running SUSE 12. There seems to be a lot of questions related to audio loop backs and piping audio around. But I haven't found any that seem to encompass all of the ways I am having issues. I have tried figuring out how to set one up using pacmd but havent had and luck. I have Dummy Output and Monitor of Dummy Output as defaults but that didnt work. When I try to open the stream i still get a no default output device error. What I am trying to find is a way to have a virtual sound card (i guess) that I can have for channels on the sip call and stream the wav file into. Any advice or direction would be very helpful. Thanks in advance

Python Twisted frameowrk transport.write to a c# socket BeginReceive reading length based message framing value

Sorry the question was badly asked. I did find the solution though. int netmsg_size = BitConverter.ToInt32(state.buffer, 0); int msg_size = IPAddress.NetworkToHostOrder(netmsg_size); This converts the network integer back into a regular integer.

I'm using length based message framing with python twisted framework with a C# client running BeginRecieve async reads and I'm having trouble grabbing the value of the length of the message. This is the twisted python code self.transport.write(pack(self.structFormat, len(string)) + string) And this is the C# code: int bytesRead = client.EndReceive(ar); if (bytesRead > 0) { int msg_size = BitConverter.ToInt32(state.buffer, 0); Problem is the len(string) value is not correct when I grab it via Bitconverter on the c# side. The value should be 15 but its coming across as 251658240. Any insight would be much appreciated.

Set executable permission from Windows host on Linux filesystem

Short answer: No. Slightly longer answer: It would perhaps not be impossible to write a Windows Samba driver which supports this, but you seem to be asking for an existing solution.

I have a python script which runs on a Windows machine. On this machine I have mounted a Samba filesystem (on a Linux host). When I now try to change file permissions on the filesystem with os.chmod(S_IXUSR) it doesn't set the excutable permission, since it is hardcoded in Windows to not do anything as some research I did suggests. Do I have any chance to change unix file permissions from a Windows host using python?

I have made a python script using python3.5, it uses many packages like tkinter, matplotlib, pylab etc. I want to convert .py file to .exe so that I can give it to people to run on windows. However I need to do the following conversion from Ubuntu only.

Python, tcpServer tcpClient, [WinError 10061]

There are most likely two reasons for that: 1.) Your server application is not listening on that particular ip/port 2.) A firewall is blocking that ip/port I would recommend checking your firewall settings. You could start with turning your firewall off to determine if it really is a firewall issue. If so, just add an accept rule for your webservice (ip:port). edit: And check your routing configuration if you are in a more or less complex network. Make sure that both networks can reach each other (e.g. ping the hosts or try to connect via telnet).

When I try to run tcpServer and tcpClient on the same local network, it works, but I can't run them on the external network. The OS refuses the connection. Main builtins.ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it I checked whether tcpServer is running or not using netstat, and it is in the listening state. What am I supposed to do?
