  * [[https://gerrit.wikimedia.org|Gerrit Mediawiki URL]]
  * [[https://www.tutorialspoint.com/gerrit/gerrit_quick_guide.htm|Tutorialspoint tutorial]]

===== Preparation =====

  * Install Git (duh)
  * Generate local SSH keys
  * Create account at Mediawiki, add SSH keys
  * Install ''git-review'' package on Linux

Test access with (should see):

<code>
$ ssh -p 29418 rpjday@gerrit.wikimedia.org

===== Cloning the test repo =====

Clone a test repo:

<code>
$ git clone ssh://rpjday@gerrit.wikimedia.org:29418/mediawiki/extensions/examples
Cloning into 'examples'...
remote: Counting objects: 44, done
remote: Finding sources: 100% (4/4)

The ''.git/config'' file:

<code>
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = ssh://rpjday@gerrit.wikimedia.org:29418/mediawiki/extensions/examples
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
        remote = origin
        merge = refs/heads/master
</code>

The ''.gitreview'' file:

<code>
[gerrit]
host=gerrit.wikimedia.org
port=29418
project=mediawiki/extensions/examples.git
track=1
</code>

Finally, there are no configured hooks:

<code>
$ ls -1 .git/hooks
applypatch-msg.sample
commit-msg.sample
fsmonitor-watchman.sample
post-update.sample
pre-applypatch.sample
pre-commit.sample
pre-merge-commit.sample
prepare-commit-msg.sample
pre-push.sample
pre-rebase.sample
pre-receive.sample
update.sample
$
</code>

===== Configuring git-review =====

Verify remotes:

<code>
$ git remote -v
origin	ssh://rpjday@gerrit.wikimedia.org:29418/mediawiki/extensions/examples (fetch)
origin	ssh://rpjday@gerrit.wikimedia.org:29418/mediawiki/extensions/examples (push)
$
</code>

==== Configuring git-review for origin ====

Point ''git-review'' at origin:

<code>
$ git config --global gitreview.remote origin
</code>

Adds .gitconfig info:

<code>
gitreview.remote=origin
</code>

===== git-review --setup =====

Set up ''git-review'':

<code>
$ git review -s
</code>

which does the following:

  * check remote access for submitting branches (if no remote access, ask for username)
  * create remote access called "gerrit" (doesn't seem to)
  * install Gerrit ''commit-msg'' hook
