# PASSING ANT TASK RESULTS TO EXTERNAL SCRIPT AS COMMANDLINE ARGUMENTS
######################################################################
# The <exec> task that is run within RSSFeedWatcherTask.java, eg.
# <exec executable="/path/to/executable"><arg line="-somearg value -someotherarg anothervalue"/></exec>
# will be passed some default commandline arguments BEFORE any you might want to specify as well (so that you can override them if you wish).
# For example, if you have these properties set in this file:
# debug=1
# feedWatchActions=//*[name() = 'entry'][1]/*[name() = 'updated']/text(); ../scripts_rss/sendEmailAlert.sh; -debug 0
# you will execute the following under the covers of the org.eclipse.releng.services.RSSFeedWatcherTask:
# <exec executable="../scripts_rss/sendEmailAlert.sh">
# <arg line="-debug 1 -feedURL http://www.eclipse.org/emf/feeds/builds.xml
# -xpath "/*[name() = 'feed']/*[name() = 'updated']/text()"
# -oldvalue "2006-05-04T12:14:33Z" -newvalue "2006-05-11T12:14:33Z" -debug 0"/>
# </exec>
# Therefore, you can use these values in the script that you execute (be it sending an email or starting a build or whatever).
# If you do NOT want to pass arguments to your executable, use the word "null" instead. This will NOT be passed to your script.
# CHECKING ANT TASK RESULTS WITHIN ANT SCRIPT
#############################################
# If you want to run some <exec> and then check the results of that execution, you can do so in the ant script that calls RSSFeedWatcherTask.
# The following properties will be set after you run the task:
# feedWatchAction.Result.0 - The result returned from the <exec> task; if set, something bad happened
# feedWatchAction.Error.0 - Details about the error that occurred, if set, something bad happened
# feedWatchAction.Output.0 - Console output from your <exec>, if any;
# this will depend on what you run in response to a feed change, and if that process produces console output
# feedWatchAction.OldValue.0 - The original value of the node you asked for, from the previous cached version of the feed
# feedWatchAction.NewValue.0 - The changed value of the node you asked for, from the latest version of the feed;
# if you asked for changes to the test status for performance tests, this could be "PASS";
# if you asked for any changes to the feed, this will be the XML datestamp of the last update, eg: 2006-05-04T12:14:33Z
#
# If you are watching for more than one condition, you can check for feedWatchAction.Result.0, feedWatchAction.Result.1, feedWatchAction.Result.2, etc.
# RUNNING NO EXTERNAL <exec>
#############################################
# If you only want to check for changes to the feed and handle the response yourself within Ant instead of an <exec>,
# simply pass in the executable as "null" to prevent any shell execution from occurring. For example:
# feedWatchActions=//*[name() = 'entry'][1]/*[name() = 'updated']/text(); null; null
# If the node is found and the feed has been changed, the property feedWatchAction.NewValue.0
# (and/or feedWatchAction.NewValue.1, feedWatchAction.NewValue.2, etc.) will be set to the new changed value.
# XPATH EXAMPLES - SAMPLE NODES TO WATCH FOR CHANGES
####################################################
# 1. to watch for ANY change in the feed, check the <feed>'s <updated> node (and respond with an email, passing -debug 1 to the mail script)
# feedWatchActions=/*[name() = 'feed']/*[name() = 'updated']/text(); ../scripts_rss/sendEmailAlert.sh; -debug 1
# 2. to watch for ANY changes in the current build, check the first <entry>'s <updated> node (and respond with an email, no commandline flags)
# feedWatchActions=//*[name() = 'entry'][1]/*[name() = 'updated']/text(); ../scripts_rss/sendEmailAlert.sh; null
# 3a. to watch for coordinated status changes, check the first <entry>'s <build> node's coordinated="" attribute (and respond using some custom Ant script)
# feedWatchActions=//*[name() = 'entry'][1]/*/*/*[name() = 'coordinated']/@status; null; null
# 3b. to watch for jar signing status changes, check the first <entry>'s <build> node's jars="" attribute (and respond using some custom Ant script)
# feedWatchActions=//*[name() = 'entry'][1]/*/*[name() = 'build']/@jars; null; null
# 3c. to watch for changes in the current build's performance test results on linux-gtk (and respond using some custom Ant script)
# feedWatchActions=//*[name() = 'entry'][1]/*/*/*/*[@type = 'performance']/*[name() = 'result'][@os = 'linux'][@ws = 'gtk']/text(); null; null
