bzr-svn fails to import

Tue Sep 9 02:10:26 BST 2008

Hi All

I've just had bazaar fail on me with a KnitCorrupt error while trying to
update one of my branches. I've been trying to fix the problem but nothing I
do seems to work. The layout of my setup is:
- Windows Vista
- Bazaar, started at 1.5, upgraded to 1.6 and upgraded again to 1.6.1.

Branches in:
bzr/main
bzr/0.1/initial

The bzr directory was initialized by bzr 1.5 using the init-repo
--rich-root-pack command. There are no sources in this directory, just the
bzr branches.
The main directory contained the original svn checkout which was done by
calling bzr checkout with the subversion branch URL. The original checkout
worked fine and there haven't been any problems with checkouts and commits
until today.
The 0.1/initial directory was branched from the main directory. This
directory was my working directory. Once a stable state was reached the
changes were merged into the main directory and committed to both bzr and
svn. Again no problems were found here except for some minor issues when
trying to perform a merge with binary files and some problems that were
caused when performing a merge that somehow created 2 directories with the
same name but different capitalization (PAC vs pac).

Today I committed some revisions to subversion and after that performed a
merge between the subversion trunk and the subversion branch (both ways to
propagate changes). When I called bzr update this failed with a KnitCorrupt
message. Following this I tried to do a nearly clean checkout (remove all
the source directories, but keep the .bzr directory in the main directory).
This didn't work unfortunately. I then upgraded to Bzr 1.6.1. and upgraded
the repositories as well (I did not upgrade the repositories when upgrading
to 1.6 originally). The upgrade didn't help so I cleared out the directories
(except for the bzr directory) and tried to do a completely new checkout.
After about an hour this checkout failed with the error mentioned below. Now
obviously I've made a ton of mistakes here (i've only started using bzr a
while back) so my questions are:
- What have I done wrong and what is the correct way of approaching my
bzr-svn setup
- Is there a way to get a good checkout from svn with bzr? We only have a
few revisions in the svn repository as we just moved to subversion from svn
but the initial checkout still takes about an hour
- Any good advice for situations like this for the next time?

Thanks

Patrick
