Description

« Hide

Right now mod_python comes with DbmSession and MemorySession. DbmSession performance can be pretty crappy if for any reason the anydbm module reverts to the dumbdbm implementation. With the current filesystems, implementing a file-based session manager should be easy and should perform well.

See the following thread : http://www.modpython.org/pipermail/mod_python/2005-April/017825.html

I've checked in a preliminary implementation based on dharana's work. We'll have to cope with a few issues (namely locking) before it is final.

OK, I have integrated FileSession into Session.py (it previously was in its own module FileSession.py). Now we need a bit of documentation...

mod_python/Session.py from (mod_python_20050518163650.tar.gz) has a typo at line +364:

        if timeout:
            self._cleanup_timeout = timeout
        else:
            self._cleanup_timeout = Session.DFT_TIMEOUT

It should be:

        if timeout:
            self._cleanup_timeout = timeout
        else:
            self._cleanup_timeout = DFT_TIMEOUT

This has been resolved a while ago. We now need some documentation.
