Hello
I am using the TracKeywordsPlugin which generates an "Add Keywords"
entry field at the bottom of each ticket HTML page. It works properly
most of the time, but sometimes this entire field is missing. What may
be the reason?
https://trac-hacks.org/wiki/TracKeywordsPlugin
Independent from this particular plugin, what mechanism may prevent
that a plugin may execute?
(Please note that generally it works, but not always.)
How shall I investigate plugin problems?
Maybe it depends on which Apache server instance is used by the
particular client (although I restarted Apache, see below...)
Some more details:
1.
We have TRAC version 1.0.4 running on Linux with Apache server.
Clients
are under Windows with Firefox browser. The plugin is installed as
Python-Egg file in the plugin-directory of the TRAC repo.
2.
Of course it looks like browser cache problem. But this cannot be the
root cause,
- because it happens also with tickets which I never visited
before.
- reloading the page does not help (Firefox, press F5 twice)
- totally different browser has same issue
3.
Restarting the Apache-Server and reloading the page cures the problem.
But after a while it re-appears with other tickets.
4.
Log-file does not show any plugin errors.
Thanks for help

Any errors in the browser console?
https://trac.edgewall.org/wiki/TracTroubleshooting#ChecktheBrowserConsole
TracKeywords should be modified to so that it doesn't use a Genshi
Transformer. I will make some changes to the code today.
- Ryan
Please try the latest from TracKeywords trunk. I modified the plugin so
that Genshi Transformer is no longer used.

Hello Ryan
I appreciate very much your work and r16925 renovation of the
TracKeywords plugin. Good work!
Anyway, using the latest trunk revision r16925 I still frequently miss
the entire keyword field. Sometimes it is there, sometimes not. Miss
rate is approx. 25%.
The browser console does not show anything related to TracKeywords.
I can confirm the issue with different browsers, on different machines,
with different Trac repos (but all on same server).
What makes this issue mysterious to me is that it is an intermediate
problem. It occurs only from time to time. May this be related to the
server-side state of the Apache-server?
Do you think it is worth to test with the trac-build-in webserver?
I have no idea ...
Thanks
Clemens
Next time you see the issue, view the page source and look whether the
keywords have been added to the page in the trac_keywords array, and if the
trac_keywords.js file has been added in a script tag.
- Ryan
Hello Ryan
I did as you requested:
The problematic HTML page differs from a correct one as follows:
- it does not load trac_keywords.css,
- it does not contains the trac_keywords JavaScript array,
- it does not load scriptrac_keywords.js.
I am not familiar with TRAC and plugin internals. But I begin to
understand that the TracKeywordsPlugin does its magic based on
JavaScript. The original page source actually never contains the final
keyword area at bottom of page. Instead the keyword area is supposed to
be inserted solely by JavaScript.
I digged into the TRAC log-file and found issues follows:
