PythonOption directive causes memory leak
-----------------------------------------
Key: MODPYTHON-60
URL: http://issues.apache.org/jira/browse/MODPYTHON-60
Project: mod_python
Type: Bug
Components: core
Versions: 3.1.4, 3.1.3, 3.2.0
Environment: Linux
Reporter: Jim Gallacher
Priority: Critical
This was previously reported on the mod_python mailing list. See
http://www.modpython.org/pipermail/mod_python/2004-April/015395.html
A memory leak results when there is a PythonOption directive in the apache
config file. Leak occurs when PythonOption is in either <VirtualHost> or
<Directory> section.
For each request, approx 25 bytes of memory is leaked per PythonOption
directive.
Methodolgy (using top to gauge memory usage, 100,000 requests per test case):
def handler(req):
req.content_type = 'text/plain'
req.write('PythonOption test\n')
return apache.OK
1. No PythonOption directives:
1.4 % MEM
2. 50 PythonOption directives:
11.3% MEM
3. 100 PythonOption directives:
25.4 % MEM
I know 50 or 100 PythonOptions is not likely in a production system, but it
clearly demonstrate the leak.
