no lp-logout command

[Samuel Bronson]

If a user does an "lp-login", but then realizes (a) their SSH public key for the system they are on isn't associated with their launchpad account and (b) they aren't sure they want it to be, there is no simple way for them to cancel the lp-login, and they won't be able to read or write lp: branches:

$ bzr pull --remember lp:bzrtools
Permission denied (publickey). < 0KB 0KB/s |
bzr: ERROR: Connection closed: please check connectivity and permissions

That's true. As a workaround, they can edit ~/.bazaar/bazaar.conf

(02:32:48) RenatoSilva: bzr branch lp:bzr-email: FATAL ERROR: Disconnected: No supported authentication methods available
(02:33:12) RenatoSilva: can't I branch as anonymous after a lp-login?
(02:39:21) jmarsden: RenatoSilva: I think you can't "undo" the lp-login easily, you have to edit or rm a file or two under .bzr/ before it will use http to access the repository. Someone was discussing this eitehr here on on #ubuntu-motu a few days ago I think.

(02:39:57) RenatoSilva: jmarsden: thanks for the info at least
(02:40:34) RenatoSilva: jmarsden: something like bzr branch --annonymous, and bzr lp-logout would be nice

This is _essential_ for people who use the Arch Linux distribution and are members of a Launchpad project; it becomes impossible to build -bzr PKGBUILDs when you're logged into Launchpad. This happens: http://omploader.org/vNHIzZw

The mentioned workaround works, but it is far from ideal.

Trent I'm not really sure why that's related, can you please post the
traceback from .bzr.log?

How come this bug is lower priority than its duplicate, #438711 ?

Sam, this doesn't require any code changes in Launchpad.

[Vincent Ladeuil (vila)]

Another workaround, available in bzr >= 2.3:

  bzr config --remove launchpad_username

Why does a read-only command like "bzr branch" use the login info at all?

Because it uses the login info to create an ssh connection, and then
it branches over that. That's a bit faster and a bit less prone to
interference from http proxies or other causes.

[William Grant (wgrant)]

And it works for private branches.

I just got bit by this bug. Had to track down this report to get a solution, then had to figure out where the config file is stored on Windows to fix it. I would recommend that if read-only operations such as pull should fail due to SSH connection issues, then simply print a warning and attempt to fall back to HTTP.
