Remote Branches Extension
This extension is not distributed with Mercurial.
Author: Augie Fackler
Quick tracking of remote branch heads for easy offline checking and reference. Similar to git's remote refs if you're familiar with git.
Configure your .hgrc to enable the extension by adding following lines:
[extensions] remotebranches = ~/path/to/remotebranches/hg_remotebranches.py
For any path in a repo's [paths] configuration section, record the branch heads and provide local tags for those branch heads. For example, if I track crew as crew = http://hg.intevation.org/mercurial/crew and mpm as mpm = http://selenic.com/hg, hg log -r 'reverse(::13855)' --limit 3 --graph produces the following output:
augie% hg log -r 'reverse(::13855)' --limit 3 --graph o 13855 ebcb000b853f 2011-03-01 23:35 -0600 durin42 | demandimport: blacklist rfc822 and mimetools to prevent spurious warnings | @ 13854[crew/default,mpm/default] 5ed036e42fd9 2011-04-01 20:40 +0200 pmezard | bugzilla: fix documentation typo | o 13853:13850,13852 3cbf5c6dcdb8 2011-04-01 13:25 -0500 mpm |\ merge with stable | |
that is, the head of default in crew is marked with a tag named crew/default and stable in mpm is mpm/stable. In the above output, revision ebcb000b853f hasn't been added to any remote repository yet, but default in both mpm and crew is at 5ed036e42fd9.
If you're on a version of Mercurial with revsets, the pushed() and upstream() convenience revsets are available. pushed() revisions are those that are pushed in any repository known by remotebranches, while upstream() shows revisions that are in paths you've described as being upstream from you. For example, one might configure .hg/hgrc for a clone of Mercurial like this (this is the config used for the above example):
[paths] default=http://hg.intevation.org/mercurial/crew crew=http://hg.intevation.org/mercurial/crew mpm=http://selenic.com/hg [remotebranches] upstream=crew,mpm
Note that the default path is the same crew, but the tags are created with the prefix crew/ and never default/. This is intentional: the default/ prefix is skipped if it is the same URL as any other path. These revsets are useful if you want to see 'hg outgoing' against multiple repositories or while disconnected.
