Trac 1.6 support

[roger.oberholtzer@…]

I have installed the plugin on Trac 1.6. It is enabled (and apache restarted). But it does not do anything. I see the following in the Trac log:

2023-10-31 09:35:18,667 Trac[main] ERROR: [10.2.10.41] Internal Server Error: <RequestWithSession "GET '/chrome/wikiautocomplete/js/wikiautocomplete.js'">, referrer 'http://10.2.10.40/systems/timeline'

I don't know if that's directly related. But as the enabled plugin does nothing, and this is in the Trac log, I thought it might be related.

Please post entire of the stacktrace. Your posted log is cut off in the middle. Also, it is unable to determine whether it is caused by this plugin and/or TracWikiPrintPlugin. Retry after uninstalling TracWikiPrintPlugin.

Replying to Jun Omae:

I see that with TrackWikiPrint enabled, TracAutocomplete stops functioning. So there is some mysterious interaction going on.

I thought I had the whole trace. The message is repeated for two files:

2023-10-31 10:51:11,198 Trac[main] ERROR: [10.2.10.41] Internal Server Error: <RequestWithSession "GET '/chrome/wikiautocomplete/js/jquery.textcomplete.min.js'">, referrer 'http://10.2.10.40/systems/admin/general/plugin'

and

2023-10-31 10:51:11,198 Trac[main] ERROR: [10.2.10.41] Internal Server Error: <RequestWithSession "GET '/chrome/wikiautocomplete/js/wikiautocomplete.js'">, referrer 'http://10.2.10.40/systems/admin/general/plugin'

The Traceback following the name of the file causing the error is otherwise identical. There was a final line (seen below) that I did not think was related to this error. Maybe it is.

Thanks. That is a duplicated TracWikiPrintPlugin's issue (#14163).

[Jun Omae]

TracAutoCompletePlugin already supports Trac 1.6 and Python 3 (#13738 [17668]).

[roger.oberholtzer@…]

I have added the change in #14163 and the error goes away. Now both plugins can coexist. I have passed this on to the wikiprint folk so they can decide what to do about that issue.
