# Perforce Workshop Jobs
#
#  Job:           The job name. 'new' generates a sequenced job number.
#
#  Status:        Job status; required field.  There is no enforced or
#                 promoted workflow for transition of jobs from one
#                 status to another, just a set of job status values
#                 for users to apply as they see fit.  Possible values:
#
#                 open - Issue is available to be worked on.
#
#                 inprogress - Active development is in progress.
#
#                 blocked - Issue cannot be implemented for some reason.
#
#                 fixed - Fixed, optional status to use before closed.
#                 
#                 closed - Issue has been dealt with definitively.
#
#                 punted - Decision made not to address the issue,
#                    possibly not ever.
#
#                 suspended - Decision made not to address the issue
#                    in the immediate future, but noting that it may
#                    have some merit and may be revisited later.
#
#                 duplicate - Duplicate of another issue that.
#
#                 obsolete - The need behind the request has become
#                    overcome by events.
#
#  Project:       The project this job is for. Required.
#
#  Severity:      [A/B/C] (A is highest)  Required.

#
#  ModifiedDate:  The date this job was last modified. Automatic.

Description:
	Enhanced mkrep.sh to support hanging an edge off a replica.
	
	It is a valid conifguration to have an edge server chained off
	a replica.  For example, you might have master in EU, an
	regional replica in the US, and edge servers in Canada and
	Mexico connected to the regional US replica (to avoid pulling
	across the pond more than once).
	
	The mkrep.sh script needs to add support for this configuration.
	Currently, the '-f <ServerID>' flag, as docmented currently, is
	only be used used for an HA of an edge server. We'll need to make
	code and docs expand the use of '-f' to include allowing an edge
	to target a replica.
	
	Sharing archives between the replica and edge is not allowed in
	this configuration (at least as of 2020.2), so we'll need a safety
	check to prevent targeting a ServerID that has lbr.replication=shared
	set. That might change in p4d in the future; if so we'll need need
	logic to account for that with a 'p4d' version check.  We'll
	also need know what configurations are supported on the target
	ServerID and enforce them. For example, can it be forwarding-standby?
	Can it be a forwarding-replica? Can it be a filtered forarding
	replica?
	
	This will require changes in the documentation embedded in
	the Helix Installer's settings.cfg for the TargetServerID setting,
	which (as with '-f <ServerID>' for mkrep.sh) indicates it is only
	to be used for the HA of an edge server.  This is tracked as
	HI-73.
