bzr-svn problem: Permission denied: ".": PROPFIND request failed on '/svn/dept/ gt/trunk'

[Brian de Alwis]

Hi everybody.  I'm encountering some problems using bzr-svn to  
interact with a project maintained on a Subversion repository.   The  
project is hosted at https://papyrus.usask.ca/svn/dept/gt/  (user:  
anonymous, no password).  I'm using bzr-svn 0.4.5 using bzr 1.0 on  
MacOSX 10.5.1 (from pkgsrc and using Python 2.4).

Unfortunately trying to do a branch of the project using bzr-svn fails:

> $ bzr branch svn+https://anonymous@papyrus.usask.ca/svn/dept/gt/trunk
> bzr: ERROR: Permission denied: ".": PROPFIND request failed on '/svn/ 
> dept/gt/trunk'

But I *have* been able to branch from other Subversion-based  
projects.  So there's something peculiar about this setup, but I  
haven't been able to figure out (i) what the problem is, and (ii) how  
to fix or work around it.  (And I have tried the development branch of  
bzr-svn to no avail.)

The ~/.bzr.log, with -Dtransport, shows:

 From poking around with pdb in svn.remote.__init__, it looks like the  
right stuff is being resolved:

> (Pdb) p svn_url
> 'https://anonymous@papyrus.usask.ca/svn/dept/gt/trunk'
> (Pdb) p _transport
> <bzrlib.plugins.svn.transport.SvnRaTransport url=svn+https://anonymous@papyrus.usask.ca 
> /svn/dept/gt/trunk>

But using SVN to look at the properties works fine:

> $ svn proplist --username anonymous https://papyrus.usask.ca/svn/dept/gt/trunk/
> Properties on 'https://papyrus.usask.ca/svn/dept/gt/trunk':
>   svn:ignore


The server logs show a different story, however: bzr-svn and svn  
differ in the URL being used for the PROPFIND.  bzr-svn seems to be  
providing the verbatim path:

> 10.225.32.88 - - [08/Jan/2008:15:56:14 -0600] "PROPFIND /svn/dept/gt/ 
> trunk HTTP/1.1" 401 1257

whereas doing a 'svn proplist' seems to be re-routed using a SVN path:

> 10.225.32.88 - anonymous [08/Jan/2008:15:55:23 -0600] "PROPFIND /svn/ 
> dept/!svn/bc/4885/gt/trunk HTTP/1.1" 207 1379


I'm at a loss as to what to try next.

> $ bzr version
> Bazaar (bzr) 1.0.0
>   Python interpreter: /usr/pkg/bin/python2.4 2.4.4.final.0
>   Python standard library: /usr/pkg/lib/python2.4

>   Bazaar configuration: /Users/bsd/.bazaar
>   Bazaar log file: /Users/bsd/.bzr.log
