Merge lp:~cjwatson/bzr/remove-register-branch into lp:bzr

[Colin Watson]

Remove `bzr register-branch`, since it has not worked for a long time.

The `bzr register-branch` command has been broken for a long time with no bug reports:

 * It relies on password authentication to Launchpad, which was deprecated in favour of SSO many years ago and disabled entirely in January 2012.
 * Its entire purpose is to create mirrored branches, which are generally deprecated in favour of code imports, and the mirroring of those branches no longer works because the relevant systems haven't had firewall-level access to the outside world for quite some time.

There's really not much point trying to resurrect this command and convert it to create code imports with modern authentication. It should just be removed.

Unmerged revisions

6623. By Colin Watson on 2017-05-23

Remove `bzr register-branch`, since it has not worked for a long time.

-    This command lists a bzr branch in the directory of branches on

-    Before using this command you must register the project to which the

 .. These may require users to change the way they use Bazaar.
 
+ * The ``bzr register-branch`` command from the Launchpad plugin has been
+   removed, because it has not worked for at least five years: it relies on
+   password authentication rather than SSO, the relevant systems no longer
+   have firewall-level access to the outside world, and in general the
+   Mirrored branch type is deprecated.  Either just push the branch to
+   Launchpad or use code imports instead
+   (https://help.launchpad.net/VcsImports).
