I don't imagine this comes up very often, but:

$ mkdir /tmp/a; cd /tmp/a; rmdir /tmp/a; python -c 'import site';
rmdir: removing directory, /tmp/a
'import site' failed; use -v for traceback

I'm quite sure nobody will want to do anything about it...

I just fixed it myself ;).  As I said before, not really a big deal, but it was an easy fix.  I've attached a patch, or you can merge my hg branch f python-trunk at

Thanks! Reopening.

A unit test is needed. Not to check the code, but to ensure that we don't break it in the future.

There was a bug in copy_absolute(): if _Py_wgetcwd() failed, the result was undefined (depending of the content of "path" buffer). Especially, absolutize() calls copy_absolute() with a buffer allocated on the stack: the content of this buffer depends on the undefined content of the stack.

Fixed in Python 3.2 (r85309+r85311), 2.7 (r85312) and 3.1 (r85313).

copy_absolute() is used (by calculate_path()) to fill sys.path.

deleted_cwd.patch, patch based on labrat's patch updated to py3k:

Procedure to test the patch:
 - go into Python source tree
 - make a directory "z"
 - enter z directory
 - delete the z directory (in another terminal)
 - run ../python
msg118479 - (view) Author: STINNER Victor (vstinner) * (Python committer) Date: 2010-10-12 22:57
Fixed in 3.2 (r85386+r85387+r85389), 2.7 (r85390), 3.1 (r85391).

Thanks labrat for your patch. I added you to Misc/ACKS.
