[Pkg-bazaar-maint] Bug#498625: bzr: Branching fails with "pack already exists", then succeeds

[Roland Mas]

Package: bzr
Version: 1.5-1.1
Severity: normal

I'm working on a patched version of GForge for a client ("foo"), where
I tried to separate each added feature into its own feature branch (I
have ~20 of these branches).  The branching scheme looks a bit like
this:

$debianrepo/gforge/debian/etch
 \-> $debianrepo/gforge/patched/4.5+php5+classrenames+etch
   \-> $gnurandalrepo/gforge/patched/foo
   \-> $gnurandalrepo/gforge/patches/foo/*

  $debianrepo is my public repository, $gnurandalrepo is the one I use
for my not-yet-public branches.  The $gnurandalrepo/gforge/patched/foo
and $gnurandalrepo/gforge/patches/foo/* branches are regularly kept
up-to-date with $debianrepo/gforge/patched/4.5+php5+classrenames+etch
with "bzr merge --lca", and patched/foo is the integration branch, on
which I also do merges from the patches/foo/* feature branches.

  Now I'm trying to prepare a deliverable for the client; that
deliverable includes all relevant branches.  So I have a script that
looks like this:
,----
| mkdir deliverable
| cd deliverable
| bzr init-repo --no-trees --format=rich-root-pack .
| mkdir gforge
| mkdir gforge/patches
| 
| bzr branch $debianrepo/gforge/debian/etch gforge/etch
| bzr branch $debianrepo/gforge/patched/4.5+php5+classrenames+etch gforge/4.5+php5+classrenames+etch
| for i in $(bzr branches $gnurandalrepo/gforge/patches/foo) ; do
|     bzr branch $gnurandalrepo/gforge/patches/foo/$i gforge/patches/$i
| done
| bzr branch $gnurandalrepo/gforge/patched/foo gforge/foo || true
| # bzr: ERROR: Pack 'a629a96b39478b58729b532fb158547c' already exists in <bzrlib.repofmt.pack_repo.RepositoryPackCollection object at 0xa276aec>
| rm -r gforge/foo
| bzr branch $gnurandalrepo/gforge/patched/foo gforge/foo
| # OK
`----

  For some reason, the first time I try to clone the patched/foo
branch, I get a failure with the above message.  Doing the very same
command again works, as does branching immediately afterwards under
another name (before the rm -r).  I can live with the workaround, but
that sounds fishy, and Jelmer suggests I report the bug.
