bzr push/pull from svn repo is unbearably slow

[nicholas a. evans]

Even when there are no revisions to pull, bzr pull takes upwards of 15 minutes. bzr push also returns 15+ minutes after the svn repo has recorded the commits. This was slow with 0.4, but this seems to have gotten slower in 0.5.

Using bzr 1.12rc1, bzr-svn 0.5 r2532.

~/src/mdlogix/crms/trunk $ bzr pull svn+https://svn.mdlogix.com/crms/trunk --lsprof-file bzr-svn-pull-prof.txt
The svn+ syntax is deprecated, use https://svn.mdlogix.com/crms/trunk instead.
No revisions to pull.
Profile data written to "bzr-svn-pull-prof.txt".

The progress bar spends most of its time "determining changes", and the numbers seem to indicate that it is iterating over every revision in the repository. Is there a way for that to be effectively cached? The repository in question has over 53,000 revisions.

Thanks for the bugreport. This should be fixed in 0.5.1, hopefully
released during the weekend.
