Re: [jira] Created: (MODPYTHON-184) Memory leak apache.table()

[Alexis Marrero]

Jim, This are my results for the memory leak search in apache.table().   The table object creates a memory pool by using apr_pool_create_ex() and destroys the pool using apr_pool_destroy(). I added a line in MpTable_New() before "return (PyObject*)t" to destroy the pool and ran 1M iterations and I notice that there was no memory leak.  Therefore the apache functions seems to be working fine. I couldn't fix the problem but here is a work around. In mod_python/util.py instead of using apache.make_table() use a regular Python dictionary.  So the line that looks like: headers = apache.make_table() now looks like: headers = {} The apache table is basically used a Python dictionary. The only functionality that is lost is that apache tables are case insensitive, and that can be easily fixed by creating a class in Python that inherits from dict type and override the __getitem__ and  __setitem__ methods. For the moment I'm going to keep this changes until modpython.org release a patch.  I spent quite sometime trying to investigate and solve the memory leak problem but the best I was able to do was to work around it. BTW,  apache.table, apache.make_table or _apache.table is only being used in mod_python/util.py. /amn On Aug 13, 2006, at 12:01 PM, Jim Gallacher (JIRA) wrote: Memory leak apache.table() --------------------------                  Key: MODPYTHON-184                  URL: http://issues.apache.org/jira/browse/MODPYTHON-184              Project: mod_python           Issue Type: Bug           Components: core     Affects Versions: 3.2.10, 3.3             Reporter: Jim Gallacher          Assigned To: Jim Gallacher There is a memory leak in apache.table(). from mod_python import apache def handler(req):     req.content_type = 'text/plain'     t = apache.make_table()     req.write('ok table:')     return apache.OK Using mpm-worker with StartServers 2, and 20000 requests results in memory consumption going from 1.2% to 9.3% per process.
