Exception when initializing large repo

[larsbj@…]

I am trying to setup trac on a largish repo (78000 revs, 12GB) The database initialization (sqlite) failes with:

 Indexing repository
Failed to initialize environment. ("Can't create a character converter from 'UTF-8' to native encoding", 12)

Not quite sure if this is a trac problem or if this is the svn bindings playing up.

Looks like the SVN bindings are involved… However, you might want to try Trac 0.9.4pre (from the svn repository: ​http://svn.edgewall.com/repos/trac/branches/0.9-stable), as it contains a fix for a memory leak during resync. It could be that the SVN binding error was triggered by an out-of-memory condition.

Also, you can try to turn on the debug output while doing resync (see TracLogging), and detect which changeset XXX brings up the exception. You can then check with svn log -v -r XXX if there's anything special concerning the character encoding of the listed paths.
