daemon

daemon - Git enabled SSH daemon

Runs the Gerrit SSH daemon on the local system, configured as per the local copy of gerrit.config.

The path to gerrit.config is read from the metadata database, which requires that all slaves (and master) reading from the same database must place gerrit.config at the same location on the local filesystem. However, any option within gerrit.config, including gerrit.basePath may be set to different values.

-DGerritServer=PATH

Path of the GerritServer.properties file, which describes how to connect to the database. To obtain a template of this file get it from the WAR:

java -jar gerrit.war --cat extra/GerritServer.properties_example >GerritServer.properties

--slave

Run in slave mode, permitting only read operations by clients. Commands which modify state such as recieve-pack (creates new changes or updates existing ones) or approve (sets approve marks) are disabled.

This command can only be run on a server which has direct connectivity to the metadata database, and local access to the managed Git repositories.

Slave daemon caches can quickly become out of date when modifications are made on the master. The following configuration is suggested in a slave to reduce the maxAge for each cache entry, so that changes are recognized in a reasonable period of time:

[cache "accounts"]
  maxAge = 5 min
[cache "accounts_byemail"]
  maxAge = 5 min
[cache "diff"]
  maxAge = 5 min
[cache "groups"]
  maxAge = 5 min
[cache "projects"]
  maxAge = 5 min
[cache "sshkeys"]
  maxAge = 5 min

and if LDAP support was enabled, also include:

[cache "ldap_groups"]
  maxAge = 5 min
[cache "ldap_usernames"]
  maxAge = 5 min

Automatic cache coherency between master and slave systems is planned to be implemented in a future version.
