 # - Generic function(s) to extract stuff from our own meta-data
 # - Logging function which automatically adds resource identifier etc

 # Portability comments:
 # o The following rely on Bourne "sh" pattern-matching, which is usually
 #   that for filename generation (note: not regexp).
 # o The "*) true ;;" clause is probably unnecessary, but is included
 #   here for completeness.
 # o The negation in the pattern uses "!".  This seems to be common
 #   across many OSes (whereas the alternative "^" fails on some).
 # o If an OS is encountered where this negation fails, then a possible
 #   alternative would be to replace the function contents by (e.g.):
 #	[ -z "`echo $1 | tr -d '[0-9]'`" ]

 # pseudo_resource status tracking function...

 # This allows pseudo resources to give correct status information.  As we add

 # These scripts work because ${HA_RSCTMP} is cleaned out every time
 # heartbeat is started.
 #
 # We create "resource-string" tracking files under ${HA_RSCTMP} in a
 # very simple way:
 #
 #	Existence of "${HA_RSCTMP}/resource-string" means that we consider
 #	the resource named by "resource-string" to be running.
 #
 # Note that "resource-string" needs to be unique.  Using the resource type
 # plus the resource instance arguments to make up the resource string
 # is probably sufficient...

 # 	where op is {start|stop|monitor|status|restart|reload|print}
 #	print is a special op which just prints the tracking file location

 #		specifying it as the third arg

 # usage: ocf_stop_processes SIGNALS WAIT_TIME PIDS
 #
 # we send signals (use quotes for more than one!) in the order
 # given; if one or more processes are still running we try KILL;
 # the wait_time is the _total_ time we'll spend in this function
 # this time may be slightly exceeded if the processes won't leave
 # 
 # returns:
 #     0: all processes left
 #     1: some processes still running
 #
 # example:
 #
 # ocf_stop_processes TERM 5 $pids
 # 
 ocf_stop_processes() {
 	local signals="$1"
 	local wait_time="$(($2/`echo $signals|wc -w`))"
 	shift 2
 	local pids="$*"
 	local sig i
 	test -z "$pids" &&
 		return 0
 	for sig in $signals KILL; do
 		kill -s $sig $pids 2>/dev/null
 		# try to leave early, and yet leave processes time to exit
 		sleep 0.2
 		for i in `seq $wait_time`; do
 			kill -s 0 $pids 2>/dev/null ||
 				return 0
 			sleep 1
 		done
 	done

 # RA tracing may be turned on by setting OCF_TRACE_RA
 # the trace output will be saved to OCF_TRACE_FILE, if set, or
 # by default to
 #   $HA_VARLIB/trace_ra/<type>/<id>.<action>.<timestamp>
 #   e.g. $HA_VARLIB/trace_ra/oracle/db.start.2012-11-27.08:37:08

 # OCF_TRACE_FILE:
 # - FD (small integer [3-9]) in that case it is up to the callers
 #   to capture output; the FD _must_ be open for writing
 # - absolute path
 #
 # NB: FD 9 may be used for tracing with bash >= v4 in case
 # OCF_TRACE_FILE is set to a path.
