Internal error when viewing changeset

[erik.haugo@…]

I'm using Trac on textdrive.

I committed my changes to svn. Then went to Trac to view the changeset from the Timeline. When I tried to open the link, I got this message:

MemoryError

This error only began happening around revision 270, so it's worked well in the past.

The changes have been added to the svn repository and I can view them from the Browse Source pages in Trac.

Any advice?

Looks like it's an out-of-memory issue, so I guess a huge file is involved in that changeset.

The error itself comes from the svn bindings (File ".../svn/core.py"), so if you're not already using the latest release of Subversion (1.4.2 at the time of this writing) you may try to upgrade, perhaps that's a bug on their side which has already been fixed.

… plus you may want to upgrade to a more recent version of Trac.

Anyway, there's not much we can do in face of a MemoryError, without the evidence of a memory leak on our side.

Please reopen if you do still have the issue with recent Trac and Subversion releases. It would be interesting to look at the memory usage pattern of the server, also.
