Internal error

[agrabarski@…]

I've installed your plugin on Trac 0.11 without problems. I've created test forum, topic and post first message on it. And now, after click on Discussion link in upper menu I see:

Trac detected an internal error: TypeError: expecting datetime, int, long, float, or None; got <type 'unicode'>

Python Traceback

Any ideas?

I'll check that lately.

I don't know how to evoke this. Can you evoke it aggain or this just happened accidentaly? Can you describe precise procedure of evokation (Values of fields you are filling in, etc)? Can you post Trac log with DEBUG level enabled? What is you server configuration?

The python traceback I get with this error

I can confirm this same bug. I created 4 forums, filling out [subject] and [description] with ONLY letters and spaces (no punctuation, no wiki-links) adding 1 moderator, and adding 1 subscriber (my email). Then I posted in one of these forums. At first, everything works fine, but then after a period of time the bug occurs. It looks like it may have to do with fetching the date/time of the last post, perhaps?

Information on the system I get this bug on

I can't post either wiki text or pictures of my pythong traceback and system info; blocked as spam.

Okay: the bug offiially occurs for me when I have 1 or more posts in any forum. I can create forums just fine; it's creating threads that produces the error.

I've been looking at the source code. It appears that the "forum.lasttopic" variable you pass into format_datetime on line 70 or so of forum-list.html is supposed to be a datetime, int, long, or float.

If I am understanding thing correctly, format_datetime and to_datetime are library functions. Can you convert forum.lastopic from unicode to a datetime object before you pass it to format_datetime? That way even if the script changes you will have already converted it and it won't throw an error.

I could be wrong though.

​This site might be of use in this situation.

[Radek Bartoň]

Great thanks for investigating this. I'll fix it as soon as I'll have spare minute...

[MN]

Quick question - do you think this could be related to the Python version I'm running? On my personal computer with Python 2.6 I don't get this bug, but on my employer's server running python 2.3, I do.

-- Thanks

[Radek Bartoň]

It's possible and it would explain why I couldn't evoke it since I wasn't using Python 2.3 for years. I may also be related to Gensi version. Could you please check what is your and your employers Genshi versions?

Genshi version is 0.5.1

And on your personal computer where it works fine?

On my personal computer I have Genshi .6

I see nothing wrong in the code and it works fine for me. I'm closing the ticket. If the problem persists on the lastest Trac, please reopen.
