Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Modules Group: Python 2.6 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Eyal Lotem (peaker) Assigned to: Nobody/Anonymous (nobody) Summary: _lsprof.c:ptrace_enter_call assumes PyErr_* is clean Initial Comment: _lsprof.c:ptrace_enter_call assumes PyErr_* has no errors. It assumes this by feeling free to call functions that PyErr_Clear and overwrite PyErr. This assumption is broken when throwing into a generator. In that case gen_send_ex(.., 1) calls the ptrace_enter_call with an exception already set. This assumption causes two bugs: A. The exception thrown into the generator is overwritten and lost. Later it was also cleared. B. gen_send_ex(..) still returns error-indication, but since the exception was cleared, you get a SystemError (error indication returned but no exception was set). To fix this, ptrace_enter_call now saves/restores the current PyErr. The attached patch was applied on the newest trunk svn. I guess it should be applicable without problems on the 2.5 bugfix branch as well. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1733973&group_id=5470 _______________________________________________ Patches mailing list Patches@python.org http://mail.python.org/mailman/listinfo/patches
