"TypeError: generate() keywords must be strings" Python 2.6 and trac 0.12

[margineanu.andrei@…]

Hi, We installed the WatchlistPlugin on our company server after making the update to trac 0.12. When watching any wiki page the following error occurs:

TypeError: generate() keywords must be strings

• in : "<path>/egg/trac/web/chrome.py", line 812, in render_template
• line 812: stream = template.generate(data)
• data: {'datetime_format': u'%Y-%m-%d %H:%i:%s', 'all': <built-in function all>, ...

It might be related to the python handling of unicode strings. See ​here and and ​here.

Thanks in advance.

Looks indeed that one of the keywords is in unicode and not a string. I have the feeling that this is only an issue with Python 2.6 and not with 2.7. Please check your log file for a trace-back and post it here. This would help me. Thanks.

Hi,

Thanks a lot for the quick update. Here is the log:

Strange, the tracelog should go all the way to the plugin. I was hoping to find the exact location in the plugin source code this way.

I now changed the code to ensure that the keywords are strings. Please try r11452 and tell me if it fixes the issue. Note that I can't replicate the error with Python 2.6.7 or 2.7.2+. Would you be able to update your Python installation, at least to a higher 2.6.x version?

Hi, Thank you for the update. I tried the fix but now I get a different error:

NameError: global name 'wldict' is not defined

in line 419: wldict['action'] = action

The Python version will not be updated because of the possible risks, so we're stuck with it - 2.6 r26:66714, Dec 3 2008, 06:05:48.

I think it's no longer a problem of the plugin. You can close the ticket.

Thank you.

Sorry, there was a minor error in my last change. Try r11454, which should work.
