Launchpad itself

Please upgrade lp:openssh to 2a format

Asked by Colin Watson

Summary: Please upgrade lp:openssh (a.k.a. lp:~vcs-imports/openssh/main) to the 2a format, if you think this is a reasonable thing to do.

Background: I'm in the process of migrating my Debian package of openssh over to Bazaar. This is a somewhat laborious process, involving constructing Bazaar branches of some historical CVS branches using cscvs (since Launchpad doesn't deal with this itself), and then transforming my CVS history into appropriately-glued-together Bazaar branches using a hacked bzr-fastimport and a considerable amount of patience and swearing at CVS. I just got to the point where I was ready to push the first stage of this (the imported upstream branches) to Launchpad for safekeeping, only to realise that my local branches are 2a and I can't push them - at any rate not without disabling stacking, which will be bandwidth-intensive - since lp:openssh is a KnitPackRepository. My experiences with trying to mix the two formats have not in general been encouraging and I'm not wildly enthusiastic about trying to convert back, nor do I particularly want to redo the conversion work I've done so far.

I imagine that upgrading the branch will be a little disruptive to other users, but there are no other openssh branches registered on Launchpad and I rather suspect that I may in fact be its major user right now ... and at worst they'll have to make sure they're using a new enough version of bzr and upgrade their local branches to match. If upgrading the branch is OK with you, it would make my life somewhat easier.

Hi Colin,

This requires a losa. I'll assign the question to them, but feel free to hassle Tom or someone if this doesn't get done :-)

Hi Losa,

Can you please log in to a code import slave and run:

sudo -u importd -H bzr log -l 1 sftp://hoover@escudero/srv/importd/www/00007270

Check that this has the same message as http://bazaar.launchpad.net/~vcs-imports/openssh/main/revision/head: (i.e., this is the right branch). Then run:

sudo -u importd -H bzr upgrade --2a sftp://hoover@escudero/srv/importd/www/00007270

I guess this'll take a few minutes, but probably not too many.

Thanks!

Michael

There's still something wrong here:

  $ bzr push -d 3.5 lp:~cjwatson/openssh/3.5
  Using default stacking branch /~vcs-imports/openssh/main at lp-64802192:///~cjwatson/openssh
  bzr: ERROR: KnitPackRepository('lp-64802192:///~vcs-imports/openssh/main/.bzr/repository')
  is not compatible with
  CHKInventoryRepository('lp-64802192:///~cjwatson/openssh/3.5/.bzr/repository')
  different rich-root support

https://code.launchpad.net/~vcs-imports/openssh/main still says "Branch format 6" and "Packs containing knits without subtree support".

Ah, sorry, I knew this but didn't say it: the upgrade I got Tom to do didn't propagate to the publicly accessible branch until the import was updated. I just forced an update, so the public branch is now in 2a format:

mwh@grond:config-manager$ bzr info nosmart+lp:openssh
Standalone branch (format: 2a)
Location:
  branch root: nosmart+bzr+ssh://bazaar.launchpad.net/~vcs-imports/openssh/main/
HPSS calls: 18 (18 vfs) SmartSSHClientMedium(connected=False, username=u'mwhudson', host='bazaar.launchpad.net', port=None)

Hope this works for you now.
