fork_fanout_dcp
Main process forking routine for an instance of the dcp command.
The routine creates forked processes of a remote copy command up to
the configured fanout value. Then output from each process is
processed. The number of currently forked processes is consistently
maintained up to the configured fanout value
Arguments:
$options - options hash table describing dsh configuration options
$resolved_targets - hash table of resolved targets and target properties
$forked_process - hash table of process information keyed by target name
$pid_targets - hash table of target names keyed by process ID
$outfh_targets - hash table of STDOUT pipe handles keyed by target name
$errfh_targets - hash table of STDERR pipe handles keyed by target name
$targets_waiting - array of targets pending remote execution
$targets_active - hash table of currently active targets with output possibly available
Returns:
None
Globals:
None
Error:
None

fork_fanout_dsh
Main process forking routine for an instance of the dsh command.
The routine creates forked processes of a remote shell command up to
the configured fanout value. Then output from each process is
processed. The number of currently forked processes is consistently
maintained up to the configured fanout value
Arguments:
$options - options hash table describing dsh configuration options
$resolved_targets - hash table of resolved targets and target properties
$forked_process - hash table of process information keyed by target name
$pid_targets - hash table of target names keyed by process ID
$outfh_targets - hash table of STDOUT pipe handles keyed by target name
$errfh_targets - hash table of STDERR pipe handles keyed by target name
$targets_waiting - array of targets pending remote execution
$targets_active - hash table of currently active targets with output possibly available
Returns:
None
Globals:
None
Error:
None

resolve_targets
Main target resolution routine. This routine calls calls all appropriate
target resolution routines to resolve target information in the
dsh command environment. Currently the routine delegates resolution to
resolve_nodes.
Arguments:
$options - options hash table describing dsh configuration options
$resolved_targets - hash table of resolved targets and target properties
$unresolved_targets - hash table of unresolved targets and target properties
$context_targets - hash table of targets grouped by context name
Returns:
None

resolve_nodes_hash
Builds the resolved nodes hash.
Does not do much anymore because we removed address resolution from
xdsh and just let ssh do it. Stayed to preserve the logic of the old
code.
Does check if the Management Node is part of the node range and sets
localhost if it is. The MN must be defined in nodelist and with
nodetype.nodetype=mn.

run_rsync_postscripts
This executes the postscript file on the nodes where
the corresponding rsync file was updated
These are the scripts after EXECUTE: in the syncfile
rsync returns a list of files that have been updated
in the form hostname: <full file path>
For example: node1: tmp/test/file1 ( yes it leaves the first / off)
This routine must match that list to the input list of postscripts.
If there is a match, for example
The postscript file is /tmp/test/file1.post and tmp/test/file1 was
updated, then it builds a xdsh command to the node to run
/tmp/test/file1.post.
On the service node, the file will be in $syncdir/tmp/test/file1.post.
Also the routine must preserve all other messages returned from rsync,
to return to the admin. It will remove the messages that the files
were updated, that is all of from hostname: <full file path>.
Input: the output from the xdcp rsync run
: @::postscripts to run
Comments:
Needs to remove the lines from rsync that are return to let
me know files were updated from the output to determine which
postscripts to run and leave any other messages
to return to the admin.

&bld_and_run_merge
This builds the parm list and executes (xdsh) the merge script file
on the nodes where
the corresponding merge file was updated.
The merge script has been previous sync'd to the nodes.
These are the scripts after MERGE: in the syncfile
rsync returns a list of files that have been updated
in the form hostname: <full file path>
For example: node1: tmp/test/file1 ( yes it leaves the first / off)
This routine must match that list to the input list of merge files.
If there is a match, it will add the merge function to
the merge script
Input: the output from the xdcp rsync run
: @::mergelines to run
Comments:
Needs to remove the lines from rsync that are return to let
me know files were updated from the output to determine which
postscripts to run and leave any other messages
to return to the admin.
Runs xdsh with input to call /opt/xcat/share/xcat/scripts/xdcpmerge.sh
which will perform the merge function on the node.
Input is the nodesyncfiledir mergefile1:orgfile mergefile2:orgfile2....] Note: MERGE is only support on Linux and for /etc/passwd,/etc/shadow,
and /etc/group
