NAME Pushmi - Subversion repository replication tool SYNOPSIS pushmi mirror /var/db/my-local-mirror http://master.repository/svn pushmi sync /var/db/my-local-mirror DESCRIPTION Pushmi provides a mechanism for bidirectionally synchronizing Subversion repositories. The main difference between Pushmi and other replication tools is that Pushmi makes the "slave" repositories writable by normal Subversion clients. CONFIGURATION Set up your local repository Create /etc/pushmi.conf and setup username and password. See t/pushmi.conf for example. pushmi mirror /var/db/my-local-mirror http://master.repository/svn Bring the mirror up-to-date. pushmi sync --nowait /var/db/my-local-mirror Configure a cron job to run this command every 5 minutes. Configure your local svn Set up your svn server to serve /var/db/my-local-mirror at "http://slave.repository/svn" For your existing Subversion checkouts, you may now switch to the slave using this command: svn switch --relocate http://master.repository/svn http://slave.repository/svn From there, you can use normal "svn" commands to work with your checkout. AUTHENTICATION The above section describes the minimum setup without authentication and authorisation. To support auth*, you need to start memcached on the "authproxy_port" port specified in pushmi.conf. For exmaple: memcached -p 7123 -dP /var/run/memcached.pid For authz_svn-controlled master repository You need to use an external mechanism to replicate the authz file and add a "AuthzSVNAccessFile" directive in the slave's slave "httpd.conf", along with whatever authentication modules and configurations. You will need additional directives in "httpd.conf" using mod_perl2: # replace with your auth settings AuthName "Subversion repository for projectX" AuthType Basic Require valid-user # here are the additional config required for pushmi PerlSetVar PushmiConfig /etc/pushmi.conf PerlAuthenHandler Pushmi::Apache::AuthCache For public-read master repository You can defer the auth* to the master on write. Put the additional config in "httpd.conf": PerlSetVar SVNPath /var/db/my-local-mirror PerlSetVar Pushmi /usr/local/bin/pushmi PerlSetVar PushmiConfig /etc/pushmi.conf AuthName "Subversion repository for projectX" AuthType Basic Require valid-user PerlAuthenHandler Pushmi::Apache::AuthCommit CONFIG FILE "pushmi" looks for /etc/pushmi.conf or wherever "PUSHMI_CONFIG" in environment points to. Available options are: username The credential to use for mirroring. password The credential to use for mirroring. authproxy_port The port memcached is running on. use_cached_auth If pushmi should use the cached subversion authentication info. Some mirror-related options are configurable in svk, in your ~/.subversion/config's "[svk]" section: ra-pipeline-delta-threshold The size in bytes that pipelined sync should leave the textdelta in a tempfile. Default is 2m. ra-pipeline-buffer The max number of revisions that pipelined sync should keep in memory when it is still busy writing to local repository. LOGGING "pushmi" uses Log::Log4perl as logging facility. Create /etc/pushmi-log.conf. See t/pushmi-log.t as exmaple. See also Log::Log4perl::Config for complete reference.
