New Revision: 74313
Added:
pypy/trunk/pypy/module/cpyext/test/date.c
- copied unchanged from r74312, pypy/branch/py-packagecontext/pypy/module/cpyext/test/date.c
Modified:
pypy/trunk/ (props changed)
pypy/trunk/pypy/module/cpyext/api.py

Log:
(fijal, afa, exarkun)
Handle extensions which init their module object with a relative name by
keeping track of what we think the name of the module being imported is
and using that instead of the name supplied by the extension.
Also (somewhat unrelated) skip a test which was reporting leaked
references.
