Cournapeau David <da...@ar.media.kyoto-u.ac.jp> added the comment: I started a patch against the trunk to handle nan/inf/infinite (I have not yet tackled the problem of negative zero).
The patch is a bit big, because I found the function quite difficult to follow, so I refactored it a bit first (replacing the state machine with the big switch with a sequential parsing). One potential problem is that I do some computation with inf to make signed infinite, I don't know if it is safe. I don't know is setting a variable to Nan is safe either. Although I tested the function in a simple main under valgrind for various legit and bogus input, there is no tests in this patch. I would like to add some, but I am not familiar with python testing, so I would be glad to receive some indications on how to do it properly. ---------- keywords: +patch nosy: +cdavid Added file: http://bugs.python.org/file12502/nan_parse.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue2121> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
