Protect against calls to deleted req object
-------------------------------------------
Key: MODPYTHON-251
URL: https://issues.apache.org/jira/browse/MODPYTHON-251
Project: mod_python
Issue Type: Improvement
Components: core
Affects Versions: 3.3.1
Environment: Replicated on:
Windows XP SP3, using Apache 2.2, Python 2.5.2
Ubuntu 7.10, using Apache 2.2, Python 2.5.2
Reporter: Jason Carver
When the logging module is passed the Apache req object as a handler, and the
req object is never removed, subsequent calls to logging crash mod_python and
Apache. I expected the page to display a Traceback instead.
This code demonstrates the crash:
def testCrash(req):
"""
Reliably crash server (on 2nd page access)
Open as: http://server/index.py/testCrash
"""
handler = logging.StreamHandler(req)
logging.getLogger('').addHandler( handler )
logging.exception('I crash')
#removing this line will cause an apache crash on the
# second web page access
logging.getLogger('').removeHandler(handler)
This code clearly has a bug if that last line is indeed commented out (causing
Apache to crash), but crashing is an unhelpful way of notifying the user of
that.
