I can't say for cetain what the cause of the segfault is, but I've posted a potential reason and patches to fix it more than once to this list. The globals for python imports are not safe, and trivial to make so. I know 3.x is the gold standard, but patching 2.x for stability shouldn't be out of the question. The calls he sites are a VERY good indicator that the global is the problem, we should just register a cleanup hook to NULL it out and recreate it again if init()s are called twice. -jack > ----- Original Message ----- > From: Peter Bowen <pzb at datastacks.com> > Date: 22 Nov 2002 16:02:24 -0500 > To: mod_python at modpython.org > Subject: [mod_python] Apache segfault when using PythonImport > > > > Apache is segfaulting when I use the PythonImport directive. > > > > I have seen it under two slightly different conditions: > > > > A) Apache 1.3.23 (from Red Hat Linux 7.3 errata), Python 2.2.2 without > > threads, and mod_python 2.7.8 > > > > In this case the backtrace shows that the segfault occurs in ap_palloc. > > The stack looks like ap_palloc -> ap_pstrdup -> ap_table_add -> > > directive_PythonImport. > > > > B) Apache 1.3.23 (as above) or Apache 1.3.27, Python 2.2.2 with threads, > > and mod_python 2.7.8 > > > > Different backtrace.
