Description Mihai Ibanescu 2001-12-07 15:47:59 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.6) Gecko/20011120

Description of problem:
Somewhere between mod_python 2.7.3 and 2.7.6 they introduced something that
broke the cleanup handler. Red Hat 7.2 ships 2.7.6.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create a mod_python handler
2. Watch it work OK without the cleanup handler defined, and segfaulting
with a defined cleanup handler
	

Actual Results:  Apache segfaults.
Since the cleanup handler is executed upon cleanup, the result is not
visible to the client, since the request is correctly served. But the httpd
process segfaults (tail -f /var/log/httpd/error.log)

Additional info:

IIRC every version after 2.7.4 has this problem.
Browsing the CVS rep doesn't show me anything strange added between 2.7.3
and 2.7.4.
I have to doublecheck if 2.7.4 is indeed the first version with the
problem. 2.7.6 which ships with Red Hat is definitely broken.

Comment 3 Mihai Ibanescu 2001-12-07 15:56:04 UTC 
Attached the configuration file and the mod_python handler.
To test this, point a browser to http://yourmachine.org/fisk

You should see something on the screen, but /var/log/httpd/error.log would show
httpd segfaulted

Incorporated into 2.7.6-5 and later.  Please also make sure the modpython.org
folks get the patch.
