UpdateTrackedBranch is an extension for the Critic code review system. Its purpose is to improve the responsiveness of Critic's tracking of branches in remote Git repositories by having those remote repositories tell Critic about updated refs, so that Critic can schedule immediate updates.
To add the extension to a Critic system, a user should create a directory named
CriticExtensions in his/her $HOME on the Critic server, and clone the
UpdateTrackedBranch repository into that directory. If done correctly, the file
$HOME/CriticExtensions/UpdateTrackedBranch/MANIFEST should exist. Also,
$HOME should be world executable, and $HOME/CriticExtensions and everything
under it should be world readable (and directories executable) so that the
Critic system is able to find and use the extension.
A Critic system administrator can also add the extension as a system extension
by doing something similar such that
/var/lib/critic/extensions/UpdateTrackedBranch/MANIFEST exists.
For more information about Critic extensions, see the [extensions tutorial] tutorial. This tutorial is also available in any Critic system that is sufficiently up-to-date to have extension support.
The extension contains a script, hooks/post-receive-or-update, that should be
installed as a Git hook in the remote repository (not in Critic's repository.)
For more details, and information on how to configure it properly, see the
documentation in the script.
It's typically best if the Git hook script can access the Critic system anonymously to notify about updated refs. For that to work, the Critic system needs to allow anonymous access. Also, a Critic system administrator needs to install the extension "universally" for it to be available anonymously.
