PYTHON_EGG_CACHE still buggy

[bruce.dubbs@…]

I just installed Trac 0.11 and ran into the Python egg cache problem again.

PythonHandler trac.web.modpython_frontend:
ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg cache:
[Errno 13] Permission denied:

I did put

PythonOption PYTHON_EGG_CACHE /srv/trac/egg-cache

outside of any virtual host.

After creating the default cache location with the proper permissions, Trac works, and the only thing in the cache is:

ls -R .python-eggs/
.python-eggs/:
Genshi-0.5.1-py2.4-linux-x86_64.egg-tmp

.python-eggs/Genshi-0.5.1-py2.4-linux-x86_64.egg-tmp:
genshi

.python-eggs/Genshi-0.5.1-py2.4-linux-x86_64.egg-tmp/genshi:
_speedups.so

Could you please provide some more information about your setup: Apache & mod_python versions, Trac version, Apache config.

You mention Trac 0.11. I believe the final fix for thi PYTHON_EGG_CACHE issue has not been released yet, so you might have to try the 0.11-stable branch, or wait for 0.11.2.

Server version: Apache/2.2.3
Server built:   Jan 15 2008 20:33:41
mod_python-3.2.8-3.1
Trac 0.11

I've worked around the problem by expanding all eggs so a cache is not needed.

The last changeset related to PYTHON_EGG_CACHE was [7420], and as described in the message, the setting requires mod_python-3.3.

So updating to Trac 0.11.1 and mod_python-3.3 should fix the issue.

I am also experiencing this problem. My system is:

Debian
Trac 0.11.2
Apache 2.2.9
mod_python 3.3.1

which means that rblank's suggestions does not work as intended. Any hint?

[Jens Rantil <jens.rantil@…>]

Sorry, running Ubuntu Intrepid and not Debian.

[Christian Boos]

Jens, can you be a bit more specific about your setup: what did you configure, what didn't work, etc.

[jens.rantil@…]

Unfortunately not. I switched to mod_wsgi and that solved my problem.

[jens.rantil@…]

Actually, I can; I wanted to specify a different location of my python egg cache. However the PythonOption did not change any behaviour at all and the egg cache was always set to DOCUMENT_ROOT whether I had that option set or not.

Closing as worksforme since last update was 6 years ago and there's nothing concrete to suggest this wasn't just an InstallationIssue. Feel free to reopen if the issue can be reproduced and TracModPython#SettingthePythonEggCache isn't effective.
