[issue2200] find_executable fails to find .bat files on win32

[Steve Dower]

Steve Dower  added the comment:

Distutils is now deprecated (see PEP 632) and all tagged issues are being 
closed. From now until removal, only release blocking issues will be considered 
for distutils.

If this issue does not relate to distutils, please remove the component and 
reopen it. If you believe it still requires a fix, most likely the issue should 
be re-reported at https://github.com/pypa/setuptools

[issue2200] find_executable fails to find .bat files on win32

[Martin v . Löwis]

Martin v. Löwis mar...@v.loewis.de added the comment:

I think the patch is incorrect. Parsing PATHEXT means that it will believe that 
all extensions listed on PATHEXT are executable. However, os.spawnv is not able 
to run them all, but only a subset. IIUC, spawnv supports (from spawnve.c)

static _TSCHAR *ext_strings[] = { _T(.cmd), _T(.bat), _T(.exe), 
_T(.com) };

PATHEXT typically includes also .js and other extensions which cannot be run 
through spawnv.

Lev Shamardin shamar...@gmail.com added the comment:

My use case was compiling PyQt4 resources and Qt Designer .ui files from setup 
script using pyrcc4 and pyuic4 commands. On windows pyrcc4 is actually a 
pyrcc4.bat file (at least it was at the time of the original bug submission - 
haven't checked current status), and find_exe could not find it.

I believe I had problems with SCons and other .py scripts that are installed as 
executable .bat files on Windows.

Another use case for .bat files is adddin extra params for executable files.

Thanks for the use cases.  I agree this is a bug, not a feature, so unless 
Tarek disagrees I will commit the last patch.

I'm not sure this requires tests.

I think distutils changes should be aimed at several versions, please correct

[issue2200] find_executable fails to find .bat files on win32

[Éric Araujo]

Éric Araujo mer...@netwok.org added the comment:

distutils bugs follow standard Python rules: They are fixed in stable and 
development branches, now 2.7, 3.1 and py3k.  If there is a security hazard, 
the fix would go into 2.6 and possibly 2.5 too.

distutils2 has to work with 2.4-2.7 and (soon) 3.1-3.2, so Tarek told me to set 
all available versions for those bugs (2.5-py3k), even if I think “3rd party” 
is more appropriate and useful (since a distutils2 bug would not for example 
block a CPython 3.2 release).

When a bug applies to distutils and distutils2, I prefer to set only versions 
relevant for distutils.  distutils2 has only one branch which is tested with 
all supported Python version, and I actually consider distutils2 a version of 
distutils: It makes more sense to me to think “this bug exists in CPython 3.1, 
3.2 and distutils2”.

Could someone provide use cases for this change?  What programs which were not 
.exe did you need to run though distutils?

anatoly techtonik [EMAIL PROTECTED] added the comment:

I've run into the same problem.

Attached patch (updated with Lev code) is almost the same except that it
doesn't attempt to return executable files without executable extension.

It also accounts that os2 executables can have arbitrary extensions
according to Perl manual.

[Lev Shamardin]

Lev Shamardin added the comment:

Here is my vision of this patch. I don't think that it is necessary to
fall back to 'com/exe/bat' if PATHEXT is not set, since it must be set
on any correctly configured Win32 platform.

Can you provide a patch which uses PATHEXT and falls back to .com, .exe

[issue2200] find_executable fails to find .bat files on win32

[Lev Shamardin]

New submission from Lev Shamardin:

distutils.spawn.find_executable appends '.exe' suffix on win32 and os2
platforms. This is incorrect behavior, since it prevents finding .bat,
.cmd and other similar files. Ether all extensions from the %PATHEXT%
must be checked or filenames both with appended suffix and without
appending suffix must be checked.
