Hello,
I am trying to branch python from lp:python into a new development branch using the "Team Collaboration, central style" (as specified in the Bazaar Manual chapter 5) where launchpad would act at the central repository and I could then do development on different machines operating more or less in lock-step with the launchpad server. (i.e. using checkout and bind).
I have been trying for days to implement this model but it is so poorly documented I am completely lost. The manual talks about starting a new repository, but I want to branch from an existing repository and use the "Team Collaboration, central style" model.
Everything I've tried has failed, and I wish the documentation could be updated with a how-to about this, but that's not the purpose of this bug. Rather, I am trying to spell out why I am trying to do what has caused my observed bug.
The main problem I have is getting my branched repository onto launchpad. When I branch to a local copy and then push, I cannot pull or checkout that branch onto any other machine, which is wrong. In fact, I get the following error:
bzr: ERROR: Repository KnitPackRepository('file:///<path>/.bzr/repository/') is not compatible with repository RemoteRepository(bzr+ssh://<uid>@bazaar.launchpad.net/%7E<uid>/python/<branch_name>/.bzr/)
When I use the create branch button on the launchpad page and select "Launchpad hosts", it creates an empty repository that is not compatible with any push operations basically because the Repository type is unknown when Python branches are rich-root-pack, whatever that means.
So I figure I need to execute an init-repo with --no-trees and --rich-root-pack to create a blank area for my branch and then branch into that from lp:python. I wanted to do a local test first before I pushed this onto python so I went to the Python Starship server and executed:
$ bzr init-repo --no-trees --rich-root-pack python_dev
$ cd python_dev/
and finally
$ bzr branch lp:python <branch_name>
That thinks for a bit, gets as far as stage 3/5 and then I get:

Does anyone know what's going on and how to do what I was trying to do in the first place. Obviously, my real problem is that I can't figure out what is the correct way to branch python onto launchpad while using the "Team Collaboration, central style" for development, but that is more a documentation bug if anything and no-one I think exists to help me with that problem. So all I have to cling to is the hope that someone can fix the hard bug of bzr branch crashing and then maybe I can use that to achieve my goals.
Thanks again! |

So I tried a third time and that locked up Starship and it had to be killed.
