"LookupError: …: not found in manifest" when looking at hg revision log

[Felix Schwarz]

I can trigger an exception in Mercurial which is not caught by the plugin when looking at a revision log for directories:

File "…/Trac-0.11.7-py2.3.egg/trac/web/main.py", line 450, in _dispatch_request
  dispatcher.dispatch(req)

$ rpm -q mercurial
mercurial-1.2-2.el4.1

This happens with my ​pycerberus repository when going to '/log/<dirname>'.

Can't seem to reproduce, at least not with Trac 0.13dev and corresponding plugin.

I'll try to test with 0.11-stable and latest corresponding plugin, in the meantime if you could find out:

• which version of the Mercurial plugin you're using
• what path precisely triggers the problem (any folder? when specifying a non-existing one?) and at which revision?

[Felix Schwarz]

Replying to cboos:

• which version of the Mercurial plugin you're using

Latest 0.11 svn

• what path precisely triggers the problem (any folder? when specifying a non-existing one?) and at which revision?

At least it was all folders I tried, for example ​/log/pycerberus

[Christian Boos]

Sorry for the delay… didn't find the time yet to try to reproduce on 0.11 (do I still have that old version installed somewhere? ;-) ).

If you have an idea where I should I look (maybe it's just that we need to catch a different exception?), I could also investigate that myself.

The actual error message is LookupError: 3@b8809e14cbf8: not found in manifest, when getting the log from your current tip. But I don't know what this "3" stands for here, and the funny thing is that tip is actually 5b6862737407 (r115 in your repo) and b8809e14cbf8 is actually an older revision (r107 in your repo).

I resurrected my 0.11 environment, the corresponding plugin and tried with your repository, but still no luck in reproducing it. Ok, I didn't test with Mercurial 1.2. Maybe that could be the problem… Can you test with something more recent, at least 1.3.x?

Oh wait … this part of the code is full of version checks, and I see that the reported version is "unknown" - with that, I assume that you're running a development version of Mercurial, and then we jump into the "then" branch, for Mercurial > (1, 3, 99). Well, either hack those lines or really upgrade to at least a version of Mercurial which correctly advertises its version number, then it should work ;-)

spot on, cboos. I filed a bug for ​Fedora EPEL.
