+Subject: [HOWTO] Using post-update hook
+Message-ID: <7vy86o6usx.fsf@assigned-by-dhcp.cox.net>
+From: Junio C Hamano <junkio@cox.net>
+Date: Fri, 26 Aug 2005 18:19:10 -0700
+Abstract: In this how-to article, JC talks about how he
+ uses the post-update hook to automate git documentation page
+ shown at http://www.kernel.org/pub/software/scm/git/docs/.
+
+The pages under http://www.kernel.org/pub/software/scm/git/docs/
+are built from Documentation/ directory of the git.git project
+and needed to be kept up-to-date. The www.kernel.org/ servers
+are mirrored and I was told that the origin of the mirror is on
+the machine master.kernel.org, on which I was given an account
+when I took over git maintainership from Linus.
+
+The directories relevant to this how-to are these two:
+
+ /pub/scm/git/git.git/ The public git repository.
+ /pub/software/scm/git/docs/ The HTML documentation page.
+
+So I made a repository to generate the documentation under my
+home directory over there.
+
+ $ cd
+ $ mkdir doc-git && cd doc-git
+ $ git clone /pub/scm/git/git.git/ docgen
+
+What needs to happen is to update the $HOME/doc-git/docgen/
+working tree, build HTML docs there and install the result in
+/pub/software/scm/git/docs/ directory. So I wrote a little
+script:
+
+ $ cat >dododoc.sh <<\EOF
+ #!/bin/sh
+ cd $HOME/doc-git/docgen || exit
+
+ unset GIT_DIR
+
+ git pull /pub/scm/git/git.git/ master &&
+ cd Documentation &&
+ make install-webdoc
+ EOF
+
+Initially I used to run this by hand whenever I push into the
+public git repository. Then I did a cron job that ran twice a
+day. The current round uses the post-update hook mechanism,
+like this:
+
+ $ cat >/pub/scm/git/git.git/hooks/post-update <<\EOF
+ #!/bin/sh
+ #
+ # An example hook script to prepare a packed repository for use over
+ # dumb transports.
+ #
+ # To enable this hook, make this file executable by "chmod +x post-update".
+
+ case " $* " in
+ *' refs/heads/master '*)
+ echo $HOME/doc-git/dododoc.sh | at now
+ ;;
+ esac
+ exec git-update-server-info
+ EOF
+ $ chmod +x /pub/scm/git/git.git/hooks/post-update
+
+There are three things worth mentioning:
+
+ - The update-hook is run after the repository accepts a "git
+ push", under my user privilege. It is given the full names
+ of refs that have been updated as arguments. My post-update
+ runs the dododoc.sh script only when the master head is
+ updated.
+
+ - When update-hook is run, GIT_DIR is set to '.' by the calling
+ receive-pack. This is inherited by the dododoc.sh run via
+ the "at" command, and needs to be unset; otherwise, "git
+ pull" it does into $HOME/doc-git/docgen/ repository would not
+ work correctly.
+
+ - This is still crude and does not protect against simultaneous
+ make invocations stomping on each other. I would need to add
+ some locking mechanism for this.
