launchpad doesn't accept branches in format developer-subtree (development format 8)

I'm somewhat uncomfortable with LP having hosted branches of unstable formats. That seems liable to result in foot-gun events and an unpleasant user experience. IMBW.

I think that's a different discussion. Bazaar supports development
formats by default - it's just that Launchpad runs an old version of
Bazaar at at the moment.

Disabling the support for *all* development formats in the bzr running
on codehosting might be a good idea, but I think that's a different bug
than updating bzr to a newer version and updating lib/lp/code/bzr.py to
match.

I would be in favor of disabling the support for development formats -
it helps keep the repositories in experimental formats contained, as
they ought to be. If you would like me to file the appropriate bugs in
Launchpad/Bazaar for this, let me know.

Cheers,

I agree its a different bug, but this bug is about the use of a
development format :P.

I'm also in favour of this; perhaps you could start a (brief) thread
on bazaar + lp-dev, to find out if there are objections.

I ended up speaking with poolie, we agree that running development formats is a bad idea. format 8 is already in our deployed bzr - so this is deliberate.

As I mentioned, I'm also not a fan of supporting development formats on
Launchpad but I don't think the last statement is true.

The currently deployed bzr is 2.2.2, which doesn't appear to have
repository development format 8; when bzr > 2.3 lands, that will fix
this bug and allow people to push development format 8 repositories
(even though Launchpad's database may not know about the format, the
smart server will).

Ah, the test wgrant did was faulty

:!bin/bzr init --development-subtree /tmp/foo
Created a standalone tree (format: development-subtree)

:!bzr push -d /tmp/foo lp:~lifeless/+junk/broken
Created new branch.

I'm going to open a new bug for limitin the formats used.

Fixed in stable r13158 <http://bazaar.launchpad.net/~launchpad-pqm/launchpad/stable/revision/13158>.
