Currently we use a perl module svn::notify. This is normally combined with svn::notify::config which uses YAML for configuration.



A user requested that we do post-commit rsyncs only when a trigger file is updated. This is a quick blogpost about doing the trigger files.


They did not require any additional security they just wanted to be able to deploy via a trigger file.


Below is the script I used to allow for trigger files:

#!/bin/sh



#CONFIG

DEBUG=""

REPOS="$1" # RESET AFTER GETOPTS

REV="$2"   # RESET AFTER GETOPTS

SVNLOOK=/usr/local/bin/svnlook

TRIGGER_PAIRS=":" #spaces between each pair



while getopts "d" optionName; do

case "$optionName" in

d) DEBUG="1";;

[?])    echo "Usage: $0 [-d]   "

esac

done

shift $(($OPTIND - 1))



# SET AFTER GETOPTS

REPOS="$1"

REV="$2"



#MAIN

# CHECK FOR TRIGGERED SYNCS

for trigger_pair in $TRIGGER_PAIRS

do

  TRIGGER_FILE=`echo $trigger_pair |awk -F:  {' print $1 '}`

  COMMIT_FILE=`echo $trigger_pair |awk -F:  {' print $2 '}`





  # DEBUG

  if [ -n "$debug" ]

  then

   echo "TRIGGER_FILE: $TRIGGER_FILE" # DEBUG

    echo "TRIGGER_PAIR $trigger_pair" # DEBUG

    echo "COMMIT_FILE: $COMMIT_FILE" # DEBUG

 fi



  if [ ! -z  "$( $svnlook changed  -r $rev $repos  | egrep "$trigger_file" $changed )" ]

  then



    # DEBUG

    if [ -n "$debug" ]

    then

      echo TRIGGER DEBUG: $REPOS/hooks/${COMMIT_FILE} "$REPOS" "$REV" # DEBUG

    fi



    $REPOS/hooks/${COMMIT_FILE} "$REPOS" "$REV"

  fi

done

# END CHECK FOR TRIGGERED SYNCS #



# NON TRIGGERED SYNCS

# CALL YAML:SVN::NOTIFY SYNC for 

$REPOS/hooks/ "$REPOS" "$REV"

# END NON TRIGGERED SYNCS

You don't need all of the debug info but I found it helpful. There is a horrible hack that I was to lazy to fix for re-setting the repo and rev after getopt.


The script can take multiply pairs of trigger files and the path to be rsynced if the trigger file was updated. All of the work is done under main. First the variables are read in and then it checks to see if the trigger file was updated using svnlook.


At the end of the script I call other svn::notify::config setups that get synced with out triggers.

Please post any comments if you would like more info on the trigger script or using svn::notify.
