200 OK error while retrieving log

[BjornW]

I tried to do a checkout of some code found here: http://svn.wp-plugins.org/bbwp2utf8 using bzr. I have updated bzr to the latest version and encountered this bug (https://bugs.launchpad.net/bzr/+bug/407343). It might something to do with failing to checkout the svn repository allthough I did get errors before and thus initiated an update to the latest stable version. Below is my .bzr.log. The first one is before I started to update bzr to 1.17. The second one is after the upgrade.

In case something went wrong with the bzr-svn created files (svn-cache and subversion.conf) I removed those and tried again. This did not solve the issue. See the trackback below:

I believe I may have also encountered the same problem (judging by the stack trace). I'm very new to bzr so I apologise if the problem is not related or I haven't provided enough information. I have starred out the URL's in the stack trace as I have been trying to run the command against the svn server in the company I work for and therefore do not want to divulge too much information by accident. Below is the command line output...

[BjornW (bjornw)]

Would it be possible for the core bzr-svn developers to let me know what I can do to help fix this bug? I'm glad to help out and get this issue fixed, but I do not know what I can do to help out. Would be great if I could use bzr with svn. Thanks for all the hard work thus far!

[Jelmer Vernooij (jelmer)]

Hi Bjorn,

Unfortunately this is a bug in the Subversion libraries that happens to be triggered by bzr-svn because it works with the full history.

E.g. try running this command:

$ svn log -v http://svn.wp-plugins.org/
svn: REPORT of '/!svn/bc/150380': 200 OK (http://svn.wp-plugins.org)

This bug will have to be fixed upstream in Subversion.

[BjornW (bjornw)]

@Jelmer, ok so I presume this bug has been reported at the svn folks' bugtracker? Do you have a ticket number so I can keep an eye on it and nudge things forward if this bug is stalled?

[Jelmer Vernooij (jelmer)]

I haven't forwarded this particular bug, but there are similar ones open in the svn bug tracker.
