# Install and maintain Gerrit Code Review.
# params:
#   mysql_host:
#     The mysql host to which gerrit should connect.
#   mysql_password:
#     The password with which gerrit connects to mysql.
#   vhost_name:
#     used in the Apache virtual host, eg., review.example.com

#       eg., https://review.example.com/
#   ssl_cert_file:
#   ssl_key_file:
#     Used in the Apache virtual host to specify the SSL cert and key files.
#   ssl_chain_file:
#     Optional, if you have an intermediate cert Apache should serve.
#   ssl_*_file_contents:
#     Optional, the contents of the respective cert files as a string. Will be
#     used to have Puppet ensure the contents of these files. Default value of
#     '' means Puppet should not manage these files.
#   openidssourl:
#     The URL to use for OpenID in SSO mode.
#   email:
#     The email address Gerrit should use when sending mail.
#   smtpserver:
#     The smtp server that Gerrit should send mail through.
#   sendemail_from:
#     gerrit.conf value for sendemail.from.

#     Gerrit configuration options; see Gerrit docs.
#   commentlinks:
#     A list of regexes Gerrit should hyperlink.
#   war:
#     The URL of the Gerrit WAR that should be downloaded and installed.
#     Note that only the final component is used for comparing to the most
#     recently installed WAR.  In other words, if you update the war from:
#
#       http://tarballs.openstack.org/ci/gerrit.war
#     to:
#       http://somewhereelse.example.com/gerrit.war
#
#     Gerrit won't be updated unless you delete gerrit.war from
#     ~gerrit2/gerrit-wars.  But if you change the URL from:
#
#       http://tarballs.openstack.org/ci/gerrit-2.2.2.war
#     to:
#       http://tarballs.openstack.org/ci/gerrit-2.3.0.war
#     Gerrit will be upgraded on the next puppet run.

#     The path to the local git replica if replicate_local is enabled
#   gitweb:
#     A boolean enabling gitweb
#   cgit:
#     A boolean enabling cgit
#   web_repo_url:
#     Url for setting the location of an external git browser
#   testmode:
#     Set this to true to disable cron jobs and replication,
#     which can interfere with testing.
#   secondary_index:
#     Set this to true to enable secondary index support
#   secondary_index_type:
#     which secondary index to use: SQL (no secondary index),
#     LUCENE (recommended), SOLR (experimental). Note: as of
#     Gerrit 2.9 LUCENE is default secondary index and SQL is
#     removed.
