StopIteration: error when viewing rev tree

Reported by: paresh.solanki@… Owned by: Emmanuel Blot
Priority: normal Component: RevtreePlugin
Severity: normal Keywords:
Cc: Trac Release: 0.12


How to Reproduce

While doing a GET operation on /revtree, Trac issued an internal error.

I have recently upgraded from Trac (postgresSQL backend) and decided to try this plugin from the 0.12 branch.

The install went well, but when I clicked on the menu bar for RevTree, I got this error after a long delay (over 2 minutes)

Ok, I can get this to work by setting the oldest revision to 7000 (we're on 8000+ revisions at the moment)

But on first clicking the rev tree option, I get the message:

Selected filters cannot render a revision tree

If I then press update (do not change any filter options), I get the rev tree I was after.

comment:2 Changed 7 years ago by paresh.solanki@…

When this fails (eg when clicking the rev tree menu item), the url is http://trac.netprod.bellfruit.local/trac/revtree

If I then change the url to http://trac.netprod.bellfruit.local/trac/revtree?author= it works.

After clicking the update button, the url contains the expected filter parameters and therefore works also.
