# This trigger script ensures that 'Map:' field on a depot spec is not the 
# unmodified server default, which stores values under the P4ROOT folder.
# The value is set to the standard SDP location for depot storage, but only
# if the current value is the unmodified server default.
#
# Enable this in the triggers table.  On a Linux server, the entry looks
# like this:
#
#   DepotSpecMapField form-out depot "/p4/common/bin/triggers/SetDefaultDepotSpecMapField.py %formfile% 1"
#
# The second paramter, a 1 (one) in the example above, is the instance number.
# If there are multiple Perforce server instances, this trigger should be
# installed in each instance, with the appropriate instance number.
#
# On a Windows server, the triggers table requires an extra argument.  It looks
# like this:
#
#   DepotSpecMapField form-out depot "python <depotdrive>\p4\common\bin\triggers\SetDefaultDepotSpecMapField.py %formfile% 1 <depotdrive>"
#
# where the second parameter is the instance number, and <depotdrive> is the
# drive letter for your depot volume, such as F:
#
# See 'p4 help triggers' for more info.

# Change User Description Committed
#5 26652 Robert Cowham This is Tom's change:

Introduced new 'Unsupported' directory to clarify that some files
in the SDP are not officially supported. These files are samples for
illustration, to provide examples, or are deprecated but not yet
ready for removal from the package.

The Maintenance and many SDP triggers have been moved under here,
along with other SDP scripts and triggers.

Added comments to p4_vars indicating that it should not be edited
directly. Added reference to an optional site_global_vars file that,
if it exists, will be sourced to provide global user settings
without needing to edit p4_vars.

As an exception to the refactoring, the totalusers.py Maintenance
script will be moved to indicate that it is supported.

Removed settings to support long-sunset P4Web from supported structure.

Structure under new .../Unsupported folder is:
   Samples/bin             Sample scripts.
   Samples/triggers        Sample trigger scripts.
   Samples/triggers/tests  Sample trigger script tests.
   Samples/broker          Sample broker filter scripts.
   Deprecated/triggers     Deprecated triggers.

To Do in a subsequent change: Make corresponding doc changes.
