#!/bin/bash ####################################################################### # # svnmirror.sh # VERSION="0.0.4" # # This script syncs changes from a developer repository to a # _READONLY_public_repository_ # # It supports pushing or pulling the changes via ssh and svn tools. # It is intended to be run manually or from cron. # ####################################################################### # # Things you have to take care of: # # 1. You need write access to the directory structure on both boxes # for more see the warning at: # http://svnbook.red-bean.com/html-chunk/ch06s03.html # # 2. For running it from cron i suggest the use of the ssh agent e.g # via keychain # in general read "man ssh-agent" and "man ssh-keygen". # # 3. Do NOT run it from post commit scripts it can lead to broken public # repositories! # # 4. You do not have to be afraid of the public repos. If the pipe is # broken nothing will be committed to it. # 21:40:47 <@sussman> tberman: welcome to atomic commits. # # 5. For local syncing use "svnadmin hotcopy" # see: "svnadmin help hotcopy" # ####################################################################### # # Authors: # - Martin Furter # - Marcus Rückert # # with suggestions from: # - tberman (#svn at freenode) # - he actually needed such a script :) # - Erik Huelsmann # - the little if for remote version :) # - status reply # - Ben Collins-Sussman # - for some help with the svn commands # - Bjørn Magnus Mathisen # - for pointing out i forgot to replace one ssh with $LSSH # TODO: # - remove bashisms and port to plain old bourne shell # # License: # The same as svn itself. for latest version check: # http://svn.collab.net/repos/svn/trunk/subversion/LICENSE # # Thanks to the subversion team for their great work. # # Links: # # If you do not like my solution check: # - svnpush # + http://svn.collab.net/repos/svn/trunk/contrib/client-side/svn-push/svn-push.c # - svn replicate # + https://open.datacore.ch/read-only/ # - SVN::Mirror and SVN::Web # + http://svn.elixus.org/repos/member/clkao/ # + http://svn.elixus.org/svnweb/repos/browse/member/clkao/ # # # Changes: # # 0.0.4 # added comandline switch -v which shows the version. # using markers now to find the config so it's not twice in this script # added/changed some more documentation # # 0.0.3 # added comandline switches: -C (create config) -f (read config file) # -h (help) -q (quiet). # # 0.0.2 # initial version # ####################################################################### # # uncomment this line for debugging # set -x # #_CONFIG_START_MARKER ####################################################################### # # svnmirror default config # # Everything starting with "R" refers to the remote host # with "L" to the local host # ####################################################################### # # Mode: # # push == Mirror from local repository to remote (readonly) repository # pull == Mirror from remote repository to local (readonly) repository # MODE="push" # Absolute path of svnlook on the local host.
