bzr-svn co crashes on Windows: exceptions.KeyError

[George V. Reilly]

The bzr-svn binaries for Windows are old and require Subversion 1.4 client binaries and Bazaar 1.5.

(Some names elided below.)

This bug is probably fixed in newer versions of bzr-svn. Any chance you can try to reproduce it with 0.4.13 ?

[George V. Reilly (georgevreilly)]

If there's an up-to-date Windows binary for bzr-svn, I'll certainly try it,
but I'm using the most recent one that I could find.

There should be a binary available for 1.9rc1.

[George V. Reilly (georgevreilly)]

I installed 1.9rc1-3 this morning. I ran
 d:\bzr-svn>bzr co http://svn/repos/cozi/trunk svn-ro
It ground away for several hours, processing about 13,000 of the 17,000+ revisions in the SVN repository. If it later fetched more revisions, I didn't see it.

Eventually, it died with
 bzr: ERROR: Unable to create symlink 'Cozi/Apps/CorporateWebsite2.0/Source/nam/resources' on this platform
This is Windows, so there are no symlinks, of course.

There is ~1GB of stuff in svn-ro/.bzr, but no files in the working directory.

BTW, I think my earlier bug report was caused in part by my confusion on how to use bzr-svn. The documentation badly needs a simple example of how to use Subversion integration.

[Jelmer Vernooij (jelmer)]

Thanks for confirming the original bug is now fixed.

You can't check out repositories that contain symbolic links on Windows although there are a few workarounds. See http://bazaar-vcs.org/WindowsSymlinkSupport for more information.

What exactly is missing from the documentation? What specifically confused you?

[George V. Reilly (georgevreilly)]

So bzr-svn simply doesn't support Windows symlinks for now?

As far as I can now tell, 'bzr co <url-to-svn-repository>' is how you're supposed to checkout a Subversion repository under Bazaar. That's not obvious and it wasn't my initial assumption -- see commands at the top of the thread.

I would suggest a brief tutorial that shows the minimum operations needed to work with an svn repo in bzr.
* Checkout the svn repo: bzr-svn's equivalent of 'svn co URL'
* Update from svn: ~= 'svn up'
* Make 2-3 changes in local bzr repo: some mixture of 'bzr add', 'bzr ci', 'bzr diff', etc
* Commit to svn: 'svn ci'

[Jelmer Vernooij (jelmer)]

bzr-svn does support symlinks. However, bzr does not support symlinks on Windows by default (you can't check out a bzr branch with symlinks on Windows either).

the quick tutorial you mention is present in the bzr user guide.
