Sheriffing/Backout-setup

In order to do backout's and checkins some setup is needed

1.) make sure you have mercurial installed 2.) Clone Repos that we as sheriff maintain like mozilla-central, mozilla-inbound, fx-team and autoland 3.) customize your .hg/hgrc of that trees as example my one for mozilla-inbound looks :

[paths]
default = http://hg.mozilla.org/integration/mozilla-inbound
default-push = ssh://hg.mozilla.org/integration/mozilla-inbound
[ui]
username = Carsten "Tomcat" Book <cbook@mozilla.com>
merge = internal:merge
[extensions]
qbackout = /sheriffs/trees/version-control-tools/hgext/qbackout
histedit =
progress =
rebase =
mq =
qimportbz = /sheriffs/trees/version-control-tools/hgext/qimportbz
transplant =
[alias]
rbimport = !hg transplant -e -s https://reviewboard-hg.mozilla.org/gecko -b $1

The whole backout is simple:

As example a developer asks you to backout changeset ab1234 so the command for the backout would be

hg qbackout -r ab1234 && hg qrefresh -e 

The hg qbackout -r <revision> should contain the revision you will backout. The hg qrefresh -e command allows you to edit the commit message for the backout, like why you backout something (example for bustage).

Backout multiple changsets ?

As example you need to backout a push that had multiple changesets/parts, the command would be

hg qbackout -r firstcset -r 2ndcset && hg qrefresh -e
