New submission from Hao Lian <hao at fogcreek.com>:
Hi! Python will crash with a None dereference error on this line:
http://selenic.com/hg/file/038b389d80f5/mercurial/filemerge.py#l28
It assumes __doc__ is always non-None, which is not true when byte-
compilation strips function docstrings out. Our use case is that we run
py2exe on our product, which uses Mercurial. (We ship the source code
separately in a ZIP per GPL.) When it imports Mercurial's modules, which
cause an import to filemerge, Python crashes on that line because py2exe
byte-compiles all the source files.
It'd be awesome a patch for this could be accepted for 2.2; I'll submit a
patch tomorrow if nobody else does (I have to head home now).
