can't import a repo with a copied-from-before-then-modified state

[radix@…]

A repository that's had the following done:

  foo/bar/ exists at revN
  svn rm foo; svn commit
  svn cp -r 1 svn://../foo foo
  svn propset svn:ignore 'blargh' foo/bar
  svn commit

can't be imported by trac. A tar file containing a dump of such a repository and the actual command-history leading up to it is at http://twistedmatrix.com/users/exarkun/initenv-bug.tar

The error that it shows is something like:

 Indexing repository
Failed to initialize environment. ("File not found: revision 2, path '/foo/bar'", 160013)
Traceback (most recent call last):
  File "/home/trac/usr/lib/python2.4/site-packages/trac/scripts/admin.py", line 617, in do_initenv

    change.base_path, pool())
SubversionException: ("File not found: revision 2, path '/foo/bar'", 160013)

This problem showed itself when trying to import the Twisted repository.

This appears to work correctly with r2763. It's not obvious to me which changeset is responsible for fixing the problem, but if someone can track it down I think it would be a candidate for being included in a future 0.9.x release (should one happen).

alect pointed out that the fix is likely [2623].

Yes, I confirm the bug is present in 0.9.2 but not in 0.9.3 anymore. Please upgrade.

Also, if you have a very big repository, you might even want the fix for a resync memory leak that is in 0.9.4pre (svn co http://svn.edgewall.com/repos/trac/branches/0.9-stable)
