Summary: subprocess.py problems errors when calling cmd.exe
Initial Comment:
An example:
>>> import subprocess
>>> proc = subprocess.Popen('"c:\Windows\system\ping.exe" "localhost"',
>>> shell=1, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
'c:\Windows\system32\ping.exe" "localhost' is not recognized as an internal or
external command, operable program or batch file.
This normally works from the cmd.exe prompt, so the command line is being
passed incorrectly in the subprocess module.
My ACTUAL use case arises when I want to call the Microsoft compiler (CL.exe),
and add include directories that have spaces in the name. For example:
"C:\Program Files\Microsoft Visual Studio 8\VC\BIN\CL.exe" /TC /O2 /DNDEBUG /W3
/nologo /c /EHsc /errorReport:prompt /Idefault\ /I.. /I. /Idefault
/I"C:\Program Files\GnuWin32" /DWIN32 ..\pcreposix.c /Fodefault\pcreposix.obj
The fix for this problem is to modify line 765 in subprocess.py, replacing it
with:
args = comspec + " /s /c \"%s\"" % args.replace('""', '"')
The /s tells cmd.exe not to re-format the command line. We then encase the
entire command line in double quotes. I also replace occurrences of "" with "
in the arg string, in case the user already encased the command in double
quotes.
With this fix, the commands execute correctly.
