<h2 id="hooks">4. Gitolite Hooks</h2>
<p>This document creates three scripts, one is run when gitolite receives
push to a project with hook active, second script is run under root
user to allow operations where gitolite user have no rights, third one
is project specific.</p>
<p>This example try to have a separate creation of a package and its deployment,
in case deploy script is not on the same machine other method can be used to send
the package.</p>
<p>A normal package will have a files.tar with all or new files to extract,
if necessary a deleted file with the list of files to be removed and a
project file with data about the package like new hash commit, or witch
script to call to deploy.</p>
<p>Package is created under gitolite
<a href="conf/srv/gitolite/hook.sh">/srv/gitolite/deploy/hook.sh</a>
script and
<a href="conf/srv/gitolite/deploy.sh">/srv/gitolite/deploy/deploy.sh</a>,
deploy in this example is called called by cron.</p>
<h3 id="gtl-activate">4.1. Activate Hooks</h3>
<p>Example from
<a href="http://gitolite.com/gitolite/cookbook.html#v3.6-variation-repo-specific-hooks">Cookbook</a>
how to apply hooks only to certain repos. Uncomment or add
this line on <a href="conf/srv/gitolite/.gitolite.rc">/srv/gitolite/.gitolite.rc</a>,
within the %RC block;</p>
<pre>
LOCAL_CODE => "$rc{GL_ADMIN_BASE}/local",
</pre>
<p>Uncomment the 'repo-specific-hooks' line in the rc file
or add it to the ENABLE list if it doesn't exist.</p>
<pre>
# allow repo-specific hooks to be added
'repo-specific-hooks',
</pre>
<p>Create directory on gitolite-admin clone;</p>
<pre>
$ cd ~/gitolite-admin
$ mkdir -p local/hooks/repo-specific
</pre>
<p>Now add your hooks to that directory, but instead of using the
git "standard" names (pre-receive, post-receive, post-update),
you use descriptive names (e.g. "deploy", "RSS-post", etc).</p>
<p>On remote run;</p>
<pre>
# su - gitolite
$ mkdir .gitolite/local/hooks/repo-specific
$ gitolite setup
</pre>
<h3 id="gtl-deploy">4.2. Deploy and Hook script</h3>
<p>Create deploy directory on remote, /srv/gitolite/deploy
was chosen to have less impact on the package system;</p>
<pre>
$ sudo -u gitolite mkdir /srv/gitolite/deploy
</pre>
<p>Script
<a href="conf/srv/gitolite/hook.sh">/srv/gitolite/deploy/hook.sh</a>
receives call create_package "project-name" "git-dir"
"valid oldrev/invalid" "newrev" "script/to/call.sh" from gitolite hook
and creates a package.</p>
<pre>
$ sudo -u gitolite cp conf/srv/gitolite/hook.sh /srv/gitolite/deploy/
</pre>
<p>Script
<a href="conf/srv/gitolite/deploy.sh">/srv/gitolite/deploy/deploy.sh</a>
loops for each package, extracts, order commit hashes to create final
snapshot of files and call script to handle deploy.</p>
<pre>
$ sudo -u gitolite cp conf/srv/gitolite/deploy.sh /srv/gitolite/deploy/
</pre>
<h3 id="gtl-setup">4.3. Setup project hook</h3>
<p>Project hooks create a package by calling hook.sh script and
deploy a package being called by deploy.sh. Deploy script is a
simple example that handle multiple web projects.</p>
<h4>4.3.1. Hook Script</h4>
<p>Create
<a href="conf/srv/gitolite/deploy-web-doc">gitolite-admin/local/hooks/repo-specific/deploy-web-doc</a>;</p>

<p>Activate this hook, the idea is to start with this one as a template working
and then implement the final one. Edit gitolite admin configuration file and
activate:</p>
<pre>
repo doc
config gitweb.description = "Documentation"
option hook.post-receive = deploy-web-doc
</pre>
<p>Add, commit, and push the admin repo;</p>
<pre>
$ git add local/hooks/repo-specific/hook-deployweb
$ git add -u && git commit -m "added deploy hook"
</pre>
<p>Now we can test if our script is functioning by creating a branch on doc
making a random change and push;<p>
<pre>
$ cd doc
$ git checkout -b deploy_branch

<h4>4.3.3. Debuging hooks</h4>
<p>Comment gitolite admin repo script "if" and uncomment debug sections, this allow to
source the file with environment of hook. Later you can delete this branch locally and remote and start fresh. To test
if hook is called each time you push run;</p>
<pre>
$ echo $(( ( RANDOM % 10 ) +1 )) >> index.html && git add -u && git commit -m "test deploy" && git push git
</pre>
<p>See if a file was created in /srv/gitolite/deploy with name of project and
with environmental variables of gitolite script.</p>
<p>From now on you can test changes directly on
/srv/gitolite/.gitolite/local/hooks/repo-specific/hook-deployweb
and repeat above command to see the results or create a separate script with
all variables generated by above script set so you don't have to push at all.</p>
<p>Change cron to debug check root email or call deploy script directly
from command line after hook and deploy_web are working.</p>
