| 64 | |
| 65 | r""" |
| 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. |
