#10790 closed defect (fixed)

ImportError preventing plugin from being loaded

Reported by: mike.charles@… Owned by: Matoba Akihiro
Priority: normal Component: TracLinksPlugin
Severity: blocker Keywords: ImportError
Cc: Matoba Akihiro Trac Release: 0.12


I had been using the TracLinksPlugin on Trac 0.12.2 for a while, and recently migrated Trac to a new server with the same version of Python, but now using Trac 0.12.4.

The TracLinksPlugin no longer works. It tries to load, but I get the following in trac.log:

2013-01-11 16:03:02,896 Trac[loader] DEBUG: Loading TracLinks from /cpc/devtools/trac/plugins/eggs/TracLinks-0.4-py2.4.egg
2013-01-11 16:03:02,896 Trac[loader] ERROR: Skipping "TracLinks = traclinks.textbox": (can't import "ImportError: cannot import name quote_query_string")

Do you know why this might happen?

I don't know why ... trac 0.12.4 has the method:

In my PC, TracLinksPlugin works well with trac-0.12.3 + Python 2.7.3.

The import was added on changeset:12082.
If you don't need "new ticket template" and "hash link" feature,
please use source:/trunk/traclinksplugin/0.12@11593 of this plugin
or reverse patch changeset:12082 to avoid the error.

Ok, I thought of one possible reason, our Trac installation is an egg file, instead of being an unzipped egg. I asked our IT team to unzip the Trac egg installation. Once they've done that I'll try the plugin again. If that doesn't work, I'll try your suggestion.

Thanks for the fast reply!

quote_query_string is available in Trac 0.12.4, however it is unavailable in 0.12.3. We should use unicode_urlencode which is available in Trac 0.10 instead.

Ok, my thoughts in comment:2 were correct, once I unzipped the Python egg that Trac was installed as, it worked fine.

Do you want to keep this ticket open for comment:4?
