trac search pops internal error: "KeyError: u'Path'" when language = zh_CN

[lranfolder@…]

I'm setting an Apache+SVN+Trac enviroment for our project, use mod_python to integrate trac into apache.

System Information:

Trac 0.12dev-r9405 

Babel 0.9.4 

Docutils 0.6 

Genshi 0.6dev-r1096 

mod_python 3.3.1 

Pygments 1.3.1 

pysqlite 2.3.2 

Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 32 bit (Intel)] 

pytz 2010g 

setuptools 0.6c11 

SQLite 3.3.4 

Subversion 1.6.6 (r40053) 

jQuery: 1.4.2

My default language is Simplified Chinese, localization just fine, most of functions fine, but when I try to search something, Trac internal error "KeyError: u'path'" pops, then I set language to US English, then search works fine, set language back to default, error again.

I try to reinstall several times, just same, then I try to search, found nothing. So, maybe that is a problem, am I right?

[Christian Boos]

Are you sure your catalog is up to date? (see 0.12/TracInstall#InstallingTrac compile_catalog step).

[lranfolder@…]

yep, first I didn't do that, the localization not work, and trac pops error like couldn't find zh_CN things, after I did compile_catalog step just like you said, and reinstalled, the ui language turned to Chinese, and worked, but the search not worked.

I can't reproduce the error, sorry. I need more details: log in as a user with TRAC_ADMIN permissions where you have an advanced error display mode where you can find more information in the backtrace, by looking at the local variables (see also #9171 for a similar error and how we managed to find the cause).

There is some detail, when I was digging into the python trace, and click into

The details like this:

So I think maybe that is the problem, something about localization caused the template couldn't be found, is that right?

[Christian Boos]

No. That frame just happens to reference the templateNotFound exception, that's all. Look rather at the last 2 frames.

[Christian Boos]

Ok, the first two then, according to your preferred direction ;-) The ones involving i18n.py actually.

[anonymous]

3ks first :), and can you give me some advises to debug this problem? If I can trace into the procedures of that, and watch the runtime states, maybe I can locate where the exact problem is. I'm not familliar with Apache & Python things, It's almost the first time I use them, so, thanks for any helps.

[Christian Boos]

Strange, u'\u67e5\u770b %(path)s' corresponds to the following part of the catalog:

#: trac/wiki/templates/wiki_view.html:26
#, python-format
msgid "View %(path)s"
msgstr "查看 %(path)s"

No idea how this can occur in the search.html template, near the "By " fragment.

[Christian Boos]

Not sure what we can do here.

Closing? ;-)
