[issue6816] Provide CPython command line functionality via runpy module
Nick Coghlan <ncoghlan [at] gmail> added the comment:

Descoped idea to just provide runpy.run_path (filesystem path equivalent
of runpy.run_module)

[issue6816] Provide CPython command line functionality via runpy module [In reply to]
R. David Murray <rdmurray [at] bitdance> added the comment:

The windows buildbots are reporting an odd error in test_runpy. I can't
see by visual inspection why the test is failing:

[issue6816] Provide CPython command line functionality via runpy module [In reply to]
Antoine Pitrou <pitrou [at] free> added the comment:

The test is probably failing because the pattern is interpreted as a regex:
>>> re.match(r'\t', r'\t') is None
True

There is another problem, which is that test_runpy (or runpy itself) is
now leaking references:

test_runpy
beginning 6 repetitions
123456
......
test_runpy leaked [56, 56, 56] references, sum=168

Nick Coghlan <ncoghlan [at] gmail> added the comment:

The windows errors are most likely due to the fact that I'm not doubling
the backslashes in the file paths before passing them to
assertRaisesRegex() as the regular expression pattern.

The reference leak is also interesting, since there isn't any new C code
here. Although I do add quite a few new entries to the path importer
cache as part of the run_path tests - that might be enough to explain it.

Nick Coghlan <ncoghlan [at] gmail> added the comment:

Hmm, definitely not the path importer cache - regrtest already takes
that into account by reverting it to its original state before checking
the reference counts.

Nick Coghlan <ncoghlan [at] gmail> added the comment:

There's another cache in zipimport that wasn't being cleared when
hunting refleaks. I've updated that on the trunk and will include it in
the forward port to 3k (along with a fix for the Windows path separator
problem).

Nick Coghlan <ncoghlan [at] gmail> added the comment:

Hmm, I think I need to use a more robust regex escaping approach... I
never knew the OS level temp dir creation could get that creative.

Nick Coghlan <ncoghlan [at] gmail> added the comment:

I fixed the tests to use the proper escaping function from the re module
instead of directly doubling backslashes, so that error shouldn't happen
any more.

(Was it one of the unstable buildbots that picked this up? I didn't see
anything come through on the checkins list)

Buildbot failures have stopped being e-mailed long ago it seems.
(ah, you really thought our buildbots were all green in all that
time? :P)

I knew the stable list was a lot shorter than the full list, so I
thought it was remotely possible :)
