New submission from STINNER Victor <[EMAIL PROTECTED]>: _multiprocessing.Connection() allows to use any positive (or nul) number has socket handle. If you use an invalid file descriptor, poll() method may crash (especially for big positive integer). Example:
>>> import _multiprocessing >>> obj = _multiprocessing.Connection(44977608) >>> obj.poll() Erreur de segmentation (core dumped) Fix: use fstat() to make sure that the handle is valid. Attached patch implements this feature. Another solution would be to reuse code from Modules/selectmodule.c. ---------- components: Library (Lib) files: _multiprocessing_connection.patch keywords: patch messages: 69446 nosy: haypo severity: normal status: open title: _multiprocessing.Connection() doesn't check handle versions: Python 2.6 Added file: http://bugs.python.org/file10860/_multiprocessing_connection.patch _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3321> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
