BZR 2.1.2 + SVN 1.7.7 + etckeeper on Debian Squeeze

Fri Nov 2 06:33:39 UTC 2012

Summary: BZR 2.1.2 + bzr-svn + SVN 1.7.7 + etckeeper on Debian Squeeze 
produce errors.

The "fix" was: aptitude purge bzr-svn

But that's not a very good fix.

Other info: /etc/ has both /etc/.bzr/ (etckeeper) and /etc/.svn/ 
(manual, back to 1998, from RCS to CVS to SVN (2005)... :)  So BZR + 
bzr-svn + SVN + etckeeper = bad; something steps on itself.

So, first, how do I force BZR to do BZR and not SVN things when both 
.bzr and .svn exist, but without uninstalling 'bzr-svn'?

Second, should I file a bug on this and if so is anything else required? 
  And is this a BZR bug (I think so) or possibly an etckeeper bug?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Details:

I'm using BZR 2.1.2 and etckeeper on Debian Squeeze.  But long before I 
did that, I was manually doing the same thing in SVN.  I've been having 
various minor problems with this, such as "aborting commit write group: 
PointlessCommit(No changes to commit)" errors, and the last time I 
looked at the (2012-03-22) I concluded that 'etckeeper's BZR was using 
/etc/.svn/ instead of /etc/.bzr/.  Mildly annoying, but I could live 
with the problems.

Then, I upgraded to SVN 1.7.7.  I did *not* however, touch /etc/.svn in 
any way with the new SVN client, which has a new work space format 
"WSNG" that is not backward compatible.

Now 'etckeeper' operations, including 'aptitude' updates, and the daily 
commits, all barf with somewhat ironic error (traceback at bottom):
	bzr: ERROR: exceptions.NameError: global name 
'ERR_WC_UNSUPPORTED_FORMAT' is not defined

Note that the error is coming from '...plugins/svn/workingtree.py' so it 
seems that even though both .bzr and .svn exist, .svn is taking 
precedence.  That's...interesting...

'bzr st' is OK, but note the modified and unknown stuff.  That should 
not be there if 'etckeeper' was working right.  But it isn't working 
right because 'bzr add -q .' is failing as noted.

/etc# bzr st .
modified:
   ntp.conf
unknown:
   apache2/conf.d/javascript-common.conf@
   apparmor.d/abstractions/
[...]

And note that SVN has *not* yet updated to WSNG:
/etc# svn st .
svn: E155036: Please see the 'svn upgrade' command
svn: E155036: Working copy '/etc' is too old (format 10, created by 
Subversion 1.6)

(I'm also not thrilled with the "etckeeper warning: hardlinked files 
could cause problems with bzr" err, but that's a matter for another 
time, and also survivable.)
