Subprocess, WindowsError: handle invalid

[Esteban Castro Borsani]

HI! so, i'm facing this issue when trying to run an exe using subprocess.Popen from an python module.

This is the structure of my project:

--Root
----myApp.exe
----mypackage (python package)
---------script.py
---------Folder (some folder)
-------------some_script.exe

myApp.exe (the app frozen by pyinstaller), imports and calls script.py
script.py calls subprocess.Popen([get_path(), '-a', fh.name], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

Traceback (most recent call last):

File "C:\Users\Admin\Desktop\0.8.0\ochDownloader\addons\swfdump\dump.py", line 20, in get_swf_dump

p = subprocess.Popen([get_path(), '-a', fh.name], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

File "C:\Users\Admin\Desktop\pyinstaller-2.0\pyinstaller-2.0\starter\build\pyi.win32\starter\out00-PYZ.pyz\subprocess", line 672, in __init__

File "C:\Users\Admin\Desktop\pyinstaller-2.0\pyinstaller-2.0\starter\build\pyi.win32\starter\out00-PYZ.pyz\subprocess", line 774, in _get_handles

WindowsError: [Error 6] Controlador no válido

subprocess.call works properly, dont know why Popen does not.

I almost forget, Im running pyinstaller 2.0 (also tried the development version), python 2.7, Windows 7 x86.
I'm packing my application as a single file.

Please try
a) packaging in --onedir mode
b) creating a minimal example for reproducing this problem.

I did not make the time to test want you ask. But I just want it to say I solve my issue by creating a new console window.

Hi Esteban,

could you please provide more info? How could be a proper fix
incorporated into pyinstaller?

[Esteban Castro Borsani]

Nevermind, what actually solved the issue was setting "console" and/or "debug" to True in the spec file.

Also, I found this solution and it does works: http://stackoverflow.com/questions/10290990/subprocess-popen-not-working-with-pythonw-exe

Passing the stdin=subprocess.PIPE parameter does the trick.

It seems to be a bug in pythonw.exe: http://bugs.python.org/issue3905

I guess when "console" and/or "debug" are set to True, python.exe is used, if they are set to False pythonw.exe is used instead?
