Updates from the SVN master repository started to fail with error messages like this:
Byte order is not compatible at ../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/_retrieve.al) line 380, at /usr/share/perl/5.12/Memoize/Storable.pm line 21 Could not unmemoize function `lookup_svn_merge', because it was not memoized to begin with at /usr/lib/git-core/git-svn line 3213 END failed--call queue aborted at /usr/lib/git-core/git-svn line 40.
Apparently, git-svn maintains cached meta information in .git/svn/.caches
, which the Perl Storable.pm
library choked on. I
guess what happened is that Ubuntu 11.10 came with a more recent version of Perl and the Perl libraries,
and the new version of Storable.pm
did not know how to handle data stored with older versions. Again, just a guess.
Discussions at http://lists.debian.org/debian-perl/2011/05/msg00023.html, http://lists.debian.org/debian-perl/2011/05/msg00026.html
and http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=618875 suggest this may in fact a bug in the git-svn
scripts, but I did
not venture to analyse the problem any further.
Anyway, the following took care of the problem for me:
rm -rf .git/svn/.caches
