Looking deeper into it i found out that sys.path[0] is the problem, because it is initialized to "/". I fixed the problem locally by removing this element from sys.path in env.py.

Crude fix to the problem

comment:1 by Gytis Raciukaitis <gytis@…>, 14 years ago

I added crude fix to the problem due to several requests to do so. It may not be a perfect one since i'm not Python guru but it works at least.

This seems like a setuptools bug, not something that is a Trac problem. If it still occurs with the latest setuptools it should be reported there.

It seems for me it is not (just?) a problem with the setuptools. After upgrading Trac (like from 092 to 093 or from 093 to 094) to a new version the apache logs the following errors on the first request:

The last ImportError repeats how many TracProject I have.

The index page falls back to the built-in one, the custom one fails to load probably due this error.

On the index page: name of the TracProject itself is correct, but the descrption is an error.

The first TracProject shows the error:

Error ([Errno 123] Die Syntax f? Dateinamen, Verzeichnisnamen oder die Datentr䧥rbezeichnung ist falsch: '\\\\*.*')

The rest shows:

Error (cannot import name load_components)

Applying the patch mentioned above to the env.py will fix and solve this issue.

So, it would be nice to incorporate this patch in an appropriate way into the source.

I run Trac on Win2k3 with mod_python.

Sorry, it does not fall back to the built-in index page… my bad. But the rest applies.

comment:7 by Matthew Good, 14 years ago

Resolution: wontfix
Status: reopenedclosed

The patch is a potential workaround, but I don't think it should be released with Trac because this problem needs to be fixed at its source. Either you have an invalid path in the PYTHONPATH environment variable, mod_python is modifying sys.path in an invalid way, or this needs fixed in setuptools. Please check your installation, and report the problem to mod_python or setuptools if necessary.

comment:8 by anonymous, 14 years ago

Thanks for pointing this out… I've made a little search:

As your function handle(req) in modpython_frontend is called the request object already contains the trouble: req.hlist.directory: "∧\"

The function HandlerDispatch() in Callback class appends this invalid directory to the sys.path.

I had mod_python 3.1.3… upgrading to 3.2 line solves the problem. (tried 3.2.5b, 3.2.8)

We definitely need a SpamFilter that rejects comments with too many URLs…

Speaking of SpamFilter….

comment:13 by Christian Boos, 11 years ago

The above spam entries had a karma of 1. min_karma should be set to 2 (it's currently set to 0), as legitimate entries with a karma of 1 are very uncommon.
