[issue4082] python2.6 -m site doesn't run site._script() any more

Oct 8, 2008, 4:51 PM

Post #1 of 17 (886 views)

New submission from Christian Heimes <lists@cheimes.de>:

python2.6 -m site used to print some status information to the console.
python3.0 -m site and python2.5 -m site are still working as expected.
An initial debug session showed that the site module isn't imported a
second time under the name __main__. I suspect a regression in runpy or
related code.

I concur with the Christian's analysis:

$ python2.6 -m site
$ python2.6 -S -m site
[output....]

It's an *installation* of Python 2.6.0 (r26:66714, Oct 2 2008) on
Ubuntu Linux AMD64. The feature is broken on the release26-maint branch
but it works fine on the trunk.

versions: -Python 2.7

I'm setting up a 2.6 working area now - we'll see what's to be seen once
I have that up and running. None of the runpy or pkgutil stuff has been
touched in months though (since PEP 366 was implemented), so I'm a
little puzzled how it could be working on the trunk and not on the 2.6
maintenance branch.

No joy. 32-bit Ubuntu here, and "./python -m site" works fine on the 2.6
branch, as does "python2.6 -m site" after a "make altinstall".

Is this an installation you built yourself, or was it packaged by
someone else?

I build the installation myself and used "make altinstall", too. Even
the latest checkout of the 2.6 branch fails to print the site information.

Hmm, that makes for absolutely identical base systems except that mine
is i686 where yours is x86_64.

What do you see if you stick some debugging messages at module level in
site.py? (e.g. printing out __name__)

(I'll be going offline shortly - I'll have another look tomorrow night,
but since I can't reproduce this locally I'm probably not going to be
much help in figuring out where it is losing the plot)

Christian Heimes <lists@cheimes.de> added the comment:

I already added a print __name__ right before the if __name__ ==
"__main__" block. Python 2.5, trunk and 3.0 print:

site
__main__

while Python 2.6 just prints:

site
