[bug] missing subprocess module in some Windows installations makes JsonServer to don't kill himself after ST3 is closed

[finalinches]

my os is win 8.1, i user the sublime text 3(BUILD 3065)
my anaconda version is 1.4.3

when i exit the sublime,just close it
there are some python.exe still stay in my os and listen some tcp port

i have a test, when i close ST3, after some hours, i find python.exe still exist........, except i kill the python.exe

....................
so sorry open it again, but in my system it's really exist python.exe, every i time i have to kill python.exe after close the ST3

You didn't need to create another issue you could re-open #286, anyway, anaconda checks that the Sublime Text 3 process is running every five seconds, if the process is not running, then it kills itself. I need more information as this never happened before to anyone.

Please, execute the steps below and paste here your results

• Open your ST3 in a project that contains Python code so anaconda gets spawned
• Open a console in your Sublime Text 3 (View -> Show Console) and write this on it: import os; os.getpid()
• Copy the PID that you just got back from the action above, paste here and remember it as you are gonna use it in the next step
• Open a PowerShell or a cmd.exe and write: tasklist /FI PID eq <write_here_the_PID_that_you_got>, paste it's output here.
• In the same PowerShell or cmd.exe write: MIC path win32_process where "name like '%python%' get commandline, paste it's output here

the tasklist out
C:\Windows\system32>tasklist /FI "PID eq 8188"

Image Name PID Session Name Session# Mem Usage
========================= ======== ================ =========== ============
plugin_host.exe 8188 Console 1 67,664 K

In the same PowerShell or cmd.exe write: MIC path win32_process where "name like '%python%' get commandline, paste it's output here

i can't understand this option. In my system, i write this, get the output like:
C:\Windows\system32>MIC path win32_process where "name like '%python%' get comm
ndline
'MIC' is not recognized as an internal or external command,
operable program or batch file.

[DamnWidget]

That's because I had a typo, the command is WMIC

[finalinches]

C:\Windows\system32>wmic path win32_process where "name like '%python%'" get com
mandline
CommandLine

D:/Python27/python.exe -B "D:\Program Files\Sublime Text\Data\Packages\Anaconda
anaconda_lib../anaconda_server\jsonserver.py" -p neutron 51344 -e "D:/work/open
cloud/Neutron/neutron/neutron,D:\work\opencloud\Neutron\neutron\neutron,D:\work
opencloud\Autotest Code\NetnodeTest,E:\Vmvare_Host\ShareDir\myboottest\template
web,D:\work\opencloud\安全BSS\BSS_server,D:\work\opencloud\proxy,D:\work\openclo
ud\Autotest Code\proxy_test" 8188

Ok, now close your Sublime Text 3, wait one minute, run the tasklist command again to make sure that pugin_hosts is not zombie in your system and run the wmic command again.

Go to %APPDATA%\Jedi\Jedi\neutron and paste here the contents of the file anaconda_jsonserver.log

Which was the output of tasklist and wmic commands?

[finalinches]

tasklist show that ST3 had been exit，no plugin_host process

but WMIC show that the python exe is still exist

[DamnWidget]

That's hard to believe, as you can see here, the JsonServer python process uses the same tasklist command to determine if the plugins_host process is still running, then, if the PID is not in the output it just sets the self.die variable as True that makes the thread to exit the loop effectively calling self.server.shutdown that closes the handler.

I don't have access no any Windows 8 machine but this is working fine in a Windows 7 VM that I use to test AnacondaST3 in windows platform. I will expect to get errors in the anaconda_jsonserver.log comming from the asyncore loop in case that the shutdown can't be done for some reason.

[finalinches]

i have test code,and i find the code is hang at
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
output = subprocess.check_output(
['tasklist', '/FI', 'PID eq {0}'.format(PID)],
startupinfo=startupinfo
)

here,when you call the check_output, this command is not return

[DamnWidget]

Really weird, I will take a look into this issue as soon as I can install an OEM/Test Windows 8.1 VM

[finalinches]

startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW

Traceback (most recent call last):
File "<pyshell#4>", line 1, in
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
AttributeError: 'module' object has no attribute 'STARTF_USESHOWWINDOW'

[finalinches]

i think this is the reason

my python is 2.7.1

[finalinches]

ok, i have google the reason

i need to
import _subprocess

and use the
_subporcess.STARTF_USESHOWWINDOW

[finalinches]

OK, that's ok, jsonsever will exit normally
import _subprocess
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= _subprocess.STARTF_USESHOWWINDOW
output = subprocess.check_output(

[DamnWidget]

Cool, I will add an official fix for this in the next release :)

[finalinches]

:) ok,waiting the new release
