66 Call the external process_plug_in_packages.py to process the plug-in
67 packages. Return the following:
68 rc The return code - 0 = PASS, 1 = FAIL.
69 shell_rc The shell return code returned by
70 process_plug_in_packages.py.
71 failed_plug_in_name The failed plug in name (if any).
72
73 Description of arguments:
74 plug_in_packages_list A python list of plug-in directory paths.
75 call_point The call point program to be called for
76 each plug-in package (e.g. post_boot).
77 This name should not include the "cp_"
78 prefix.
79 shell_rc The user may supply a value other than
80 zero to indicate an acceptable non-zero
81 return code. For example, if this value
82 equals 0x00000200, it means that for each
83 plug-in call point that runs, a 0x00000200
84 will not be counted as a failure.
85 stop_on_plug_in_failure If this parameter is set to 1, this
86 program will stop and return non-zero if
87 the call point program from any plug-in
88 directory fails. Conversely, if it is set
89 to false, this program will run the call
90 point program from each and every plug-in
91 directory regardless of their return
92 values. Typical example cases where you'd
93 want to run all plug-in call points
94 regardless of success or failure would be
95 "cleanup" or "ffdc" call points.
96 stop_on_non_zero_rc If this parm is set to 1 and a plug-in
97 call point program returns a valid
98 non-zero return code (see "shell_rc" parm
99 above), this program will stop processing
100 and return 0 (success). Since this
101 constitutes a successful exit, this would
102 normally be used where the caller wishes
103 to stop processing if one of the plug-in
104 directory call point programs returns a
105 special value indicating that some special
106 case has been found. An example might be
107 in calling some kind of "check_errl" call
108 point program. Such a call point program
109 might return a 2 (i.e. 0x00000200) to
110 indicate that a given error log entry was
111 found in an "ignore" list and is therefore
112 to be ignored. That being the case, no
113 other "check_errl" call point program
114 would need to be called.
115 release_type The type of release being tested (e.g.
116 "obmc", "op", "fips"). This influences
117 which integrated plug-ins are selected.
118 quiet If quiet is set to 1, this function will
119 NOT write status messages to stdout. This
120 will default to the global quiet program
121 parm or to 0.
122 debug If this parameter is set to 1, this
123 function will print additional debug
124 information. This is mainly to be used by
125 the developer of this function. This will
126 default to the global quiet program parm
127 or to 0.
