r"""
Call the external process_plug_in_packages.py to process the plug-in
packages. Return the following:
rc The return code - 0 = PASS, 1 = FAIL.
shell_rc The shell return code returned by
process_plug_in_packages.py.
failed_plug_in_name The failed plug in name (if any).
Description of arguments:
plug_in_packages_list A python list of plug-in directory paths.
call_point The call point program to be called for
each plug-in package (e.g. post_boot).
This name should not include the "cp_"
prefix.
shell_rc The user may supply a value other than
zero to indicate an acceptable non-zero
return code. For example, if this value
equals 0x00000200, it means that for each
plug-in call point that runs, a 0x00000200
will not be counted as a failure.
stop_on_plug_in_failure If this parameter is set to 1, this
program will stop and return non-zero if
the call point program from any plug-in
directory fails. Conversely, if it is set
to false, this program will run the call
point program from each and every plug-in
directory regardless of their return
values. Typical example cases where you'd
want to run all plug-in call points
regardless of success or failure would be
"cleanup" or "ffdc" call points.
stop_on_non_zero_rc If this parm is set to 1 and a plug-in
call point program returns a valid
non-zero return code (see "shell_rc" parm
above), this program will stop processing
and return 0 (success). Since this
constitutes a successful exit, this would
normally be used where the caller wishes
to stop processing if one of the plug-in
directory call point programs returns a
special value indicating that some special
case has been found. An example might be
in calling some kind of "check_errl" call
point program. Such a call point program
might return a 2 (i.e. 0x00000200) to
indicate that a given error log entry was
found in an "ignore" list and is therefore
to be ignored. That being the case, no
other "check_errl" call point program
would need to be called.
release_type The type of release being tested (e.g.
"obmc", "op", "fips"). This influences
which integrated plug-ins are selected.
quiet If quiet is set to 1, this function will
NOT write status messages to stdout. This
will default to the global quiet program
parm or to 0.
debug If this parameter is set to 1, this
function will print additional debug
information. This is mainly to be used by
the developer of this function. This will
default to the global quiet program parm
or to 0.
