Hudson plugin, python 2.4 and trac-0.11.6stable doesn't start

[brett.dellegrazie@…]

Hi,

After a clean install of Trac (served via mod_wsgi) and installation of the Hudson plugin, Trac no longer starts.

versions: OS: RHEL5.3 Trac: 0.11.6stable r8448 mod_wsgi: 2.1-2.el5 python: 2.4.3-24.el5_3.6 HudsonTracPlugin: r6343 (from local checkout of source)

The stack trace I get is:

Traceback (most recent call last):

hope you can help.

Thanks,

It looks like you may have misconfigured the feed_url option - make sure it is an absolute url, i.e. including a scheme, e.g. 'http://localhost/hudson/rssAll' and not just '/hudson/rssAll'.

Hi,

I haven't misconfigured the feed_url option (that I can see) my trac.ini is below. I have also attached the trac.log in DEBUG mode from startup.

[hudson] feed_url=​http://buildsystem.iris2.local/rssAll username= password= display_subprojects=false main_page=​http://buildsystem.iris2.local/ display_in_new_tab=true alternate_success_icon=true display_build_descriptions=true

[hudson]
feed_url=http://buildsystem.iris2.local/rssAll

Thanks. Hmm, something's odd - for some reason the feed-url isn't being parsed properly. Can you add the following line to HudsonTracPlugin.py, just after line 50 (i.e. after the url is parsed but before base_url gets set):

  self.env.log.info("Using feed at '%s' (%s)" % (self.feed_url, url_parts))

and then show me the output in the log?

TIA.

Hi,

I have done as you requested, the new trac.log is attached. Thanks for your help with this.

Thanks. Ok, looks like the issue is that you're using python 2.4 but the plugin is using something that was added in 2.5. Checking in a fix now.

(In [6371]) Fix #5636. urlparse added attributes to the result in python 2.5, so using those breaks installations using 2.4. Therefore changed to use indexes instead.
