[feature] UI for changing branch stacking

Ok after some testing I believe it is impossible to restack any lp branch onto another lp branch.

eg if you run

$bzr reconfigure lp:~someone/project/branch --stacked-on bzr+ssh://bazaar.launchpad.net/~someoneelse/project/other

then

$bzr info lp:~someone/project/branch
<tratatata>
Related branches:
stacked on: ../../~someoneelse/project/other

This is not recongnised by launchpad as a valid brach (Branch has errors)

Where the correct result should be:

$bzr info lp:~someone/project/branch
<tratatata>
stacked on: bzr+ssh://bazaar.launchpad.net/~someoneelse/project/other

Basicly bazaar did url expansion to local directory on launchpad, when it shouldn't have since it's hosted branch.

A solution on irc was to still use bzr reconfigure and then use bzrlib to reset stacked-on branch to correct url.

I would like to request launchpad UI to change stacking in branch configs (next to change branch owner & branch name)

I think you should be passing a relative url to the stacked-on setting.

If this bug is asking for a Launchpad UI to change this, then I'm not sure what change is wanted in bzr.

I think this is already addressed in bzr through 'reconfigure --stacked-on/--unstacked'. If you think that's not enough, please reopen the bug and tell us why and how.

The how:

$ bzr ci --unchanged -m "Commit 1"
$ bzr push lp:~dmitrij.ledkov/xiphos/commit-1
Using default stacking branch /~xiphos-devel/xiphos/trunk at
lp-64802192:///~dmitrij.ledkov/xiphos
Created new stacked branch referring to /~xiphos-devel/xiphos/trunk.

$ bzr ci --unchanged -m "Commit 2"
$ bzr push lp:~dmitrij.ledkov/xiphos/commit-2
Using default stacking branch /~xiphos-devel/xiphos/trunk at
lp-64802192:///~dmitrij.ledkov/xiphos
Created new stacked branch referring to /~xiphos-devel/xiphos/trunk.

$ bzr reconfigure lp:~dmitrij.ledkov/xiphos/commit-2 --stacked-on
lp:~dmitrij.ledkov/xiphos/commit-1
bzr: ERROR: Not a branch:
"/home/dmitrij/src/upstream/xiphos/bla/lp:~dmitrij.ledkov/xiphos/commit-1/".

#trying harder
$ bzr reconfigure lp:~dmitrij.ledkov/xiphos/commit-2 --stacked-on
bzr+ssh://bazaar.launchpad.net/~dmitrij.ledkov/xiphos/commit-1
bzr+ssh://bazaar.launchpad.net/~dmitrij.ledkov/xiphos/commit-2/ is now
stacked on ../commit-1

lp:~dmitrij.ledkov/xiphos/commit-2 is now a broken branch (still up on
launchpad)

The why: resulting branch is broken (not valid).

relative stacked paths work in the core. I think this is an lp code issue really.

Michael, is this where we should modify the stacked on url to be relative properly on the codehost side?

Yes, probably.

This whole area basically makes me want to cry.
