bzr unable to branch underneath checkout inside shared repo

[Alexander Belchenko]

This is very complex issue to describe by words. bzr fails to create branch nested into checkout in the case when checkout does not use shared repository, but in fact there is shared repository. IIUC bzr at the beginning of branch operation opened shared repo but then it tries to open it again and see non-shared repo inside checkout and fails at this step with error.

I'd better to show you sequence of commands:

C:\Temp\3>bzr init a
Created a standalone tree (format: pack-0.92)

C:\Temp\3>bzr ci a -m1 --unchanged
Committing to: C:/Temp/3/a/
Committed revision 1.

C:\Temp\3>mkdir repo

C:\Temp\3>bzr co a repo/a-co

C:\Temp\3>bzr init-repo repo
Shared repository with trees (format: pack-0.92)
Location:
  shared repository: repo

C:\Temp\3>bzr branch a repo/a-co/a-branch
bzr: ERROR: No repository present: "file:///C:/Temp/3/repo/a-co/a-branch/"

Here is relevant part of .bzr.log:

I can't reproduce this.

Right, you've created a situation where there's a shared repo at
repo/, a standalone checkout at repo/a-co, and then you're trying to
make a new branch, presumably using repo/ at repo/a-co/a-branch.

This script copy&pasted from your example works for me on Linux with 1.16dev. Can you change it to make it fail?

It works for me with official 1.15 sources. Perhaps it fixed between
1.14 and 1.15.

Hmm, on my current system bug could reproduced with official 1.13, but
not with official 1.14rc2.
