#################################

# submit_request will take an xCAT command and pass it to the xCAT
|
|
# server for execution.
|
|
#
|
|
# If the XCATBYPASS env var is set, the connection to the server/daemon
|
|
# will be bypassed and the plugin will be called directly. If it is
|
|
# set to one or more directories (separated by ":"), all perl modules
|
|
# in those directories will be loaded in as plugins (for duplicate
|
|
# commands, last one in wins). If it is set to any other value
|
|
# (e.g. "yes", "default", whatever string you want) the default plugin
|
|
# directory /opt/xcat/lib/perl/xCAT_plugin will be used.
|
|
#
|
|
# Input:
|
|
# Request hash - A hash ref containing the input command and args to be
|
|
# passed to the plugin. The the xcatd daemon (or this routine when
|
|
# XCATBYPASS) reads the {noderange} entry and builds a flattened array
|
|
# of nodes that gets added as request->{node}
|
|
# The format for the request hash is:
|
|
# { command => [ 'xcatcmd' ],
|
|
# noderange => [ 'noderange_string' ],
|
|
# arg => [ 'arg1', 'arg2', '...', 'argn' ]
|
|
# }
|
|
# Callback - A subroutine ref that will be called to process the output
|
|
# from the plugin.
|
|
#
|
|
# NOTE: The request hash will get converted to XML when passed to the
|
|
# xcatd daemon, and will get converted back to a hash before being
|
|
# passed to the plugin. The XMLin ForceArray option is used to
|
|
# force all XML constructs to be arrays so that the plugin code
|
|
# and callback routines can access the data consistently.
|
|
# The input request and the response hash created by the plugin should
|
|
# always create hashes with array values.

# handle_response is a default callback that can be passed into submit_response()

|
|
# The normal flow is:
|
|
# -> client cmd (e.g. nodels, which is just a link to xcatclient)
|
|
# -> xcatclient
|
|
# -> submit_request()
|
