• Synopsis: A new option added to pbs_benchpress command to enable saving post analysis data on test case failure in PTL
  
• Details: To enable saving post analysis data on test case failure in PTL, new command line option will be introduced called '--post-analysis-data=<dir>' in pbs_benchpress command. By default PTL will not save any post analysis data in failure case. When enabled, PTL will store post analysis data on failure in given <dir> (if <dir> does not exits then PTL will create it, with 0755 permission and owner will be current user (i.e. use user who invoked pbs_benchpress command)) in below format

  <dir>/<test suite 1 name>/

                                        <test case 1 name>/

                                                                       logfile_<status>

                                                                       PBS_<hostname>.tar.gz

                                        ...

                                        <test case n name>/

                                                                       logfile_<status>

                                                                       PBS_<hostname>.tar.gz

         ...

         <test suite n name>/

                                        <test case 1 name>/

                                                                       logfile_<status>

                                                                       PBS_<hostname>.tar.gz

                                        <test case 2 name>/

                                                                       logfile_<status>

                                                                       PBS_<hostname>.tar.gz

                                        ...

                                        <test case n name>/

                                                                       logfile_<status>

                                                                       PBS_<hostname>.tar.gz

  
  This post analysis data includes following data:
  • logfile_<status of test case>
    • This file contains PTL logs of current test case for which post analysis data is being stored
    • <status of test case> can be one of following:
      • PASS
      • SKIP
      • FAIL
      • ERROR
      • TIMEDOUT
    • Also in last line of this file will have time taken by current test case
  • PBS_<hostname>.tar.gz
    • This file is nothing but PBS diag saved by pbs_diag command with renamed as PBS_<hostname>.tar.gz from pbs_diag_yymmdd_hhmmss.tar.gz
      
      • PTL will run pbs_diag with following options
        • -f: for running pbs_diag in non-interactive mode
        • -j <jobid1>,<jobid2>,...,<jobidn>: comma separated list of job ids (if any)
        • -d 2: To save PBS logs for last two days
          • 2 days because there might be chances that date can switch (like midnight) while PTL is running test
      • Also PTL will run pbs_diag command with -g <path to core file> if all core files found in PBS_HOME directory
        
        • The output of above command will be store in <core file name>.out
        • After taking pbs_diag output for core file, core file will be deleted from PBS_HOME directory
