Hi there,
today I tried connecting Eclipse to Trac using Mylyn Trac Connector
(3.4.1) and tracxmlrpc (1.1.0). I partially succeeded, but the
important things did not work.
I'm using an Agilo Windows Installer Setup (v 1.3.0.7). Added trac xml-
rpc and trac httpauth plugins (latest versions) to the plugins dir
(tried both directories (tracenv/test/plugins and lib/site-packages -
no difference).
First on the things that worked: I was able to create a Trac Task
Repository and all types of connections worked (anonymous,
authenticated, Web and XML-RPC) - in any combination when testing with
the 'Validate Settings' button. I was also able create a query using a
Web connection. Creation of a task then opens the webbrowser showing
the Trac/Agilo interface to create a new ticket - not that bad, but I
was looking for full integration into Eclipse. So I went for XML-RPC.
So what did not work was the creation of a query using XML-RPC -
neither authenticated nor anonymous (both were granted the XML_RPC
permissions).
In both cases an error came up showing 'RPC method
"ticket.milestone.getAll" not found'. Trac.log:
--------------------------------------- 8<

After some time with Google I found this:

Modified the python script, rebuild the python egg for xmlrpc, copied
it, restarted the server - now I get a 'HTTP Error 500' when trying to
'Update Attributes from Repository' in the query window. So I went
back to the old xmlrpc egg (no trac.log entry for this).
Another issue (guess it's related) is that when closing the query
window I also get a 'HTTP Error 500' (this time as a pop-up alert) -
this also came up before modifying the xmlrpc egg. The trac.log tells
me for this error:

Now I've got no clue what to do... any suggestions? (maybe I missed
something simple)
