# library for shell scripts, but for the time being, we'll just use it
# ourselves...
#
# TODO wish-list:
# - Generic function for evaluating version numbers
# - Generic function(s) to extract stuff from our own meta-data
# - Logging function which automatically adds resource identifier etc
# prefixes
# TODO: Move more common functionality for OCF RAs here.
#
# This was common throughout all legacy Heartbeat agents

# 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
# resource monitoring, and better resource tracking in general, this will
# become essential.
#
# 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...
#
# usage: ha_pseudo_resource resource-string op [tracking_file]
# where op is {start|stop|monitor|status|restart|reload|print}
# print is a special op which just prints the tracking file location
# user can override our choice of the tracking file location by
# specifying it as the third arg
# Note that all operations are silent...
