    • code-checks with cms.weekN.PR_hash/tool-conf-version: In case an external update is needed to run code-checks (e.g. due to interface changes in header files) then first run PR tests for cmsdist/external which should deploy externals on CVMFS. Then request the code-checks with the newly deployed externals tools configuration e.g. code-checks with cms.week0_PR_01234567/47.0-cms2 (external tools configuration is available via cmsdist PR summary page).
    • code-checks and apply patch: This command can be used to run code-checks and apply the needed code-checks changes.

    • ignore clang-warnings: To ignore clang warnings results
    • ignore build-warnings: To ignore build warnings results
    • ignore tests-rejected with (manual-override|ib-failure|external-failure): To ignore test and relval failures:
      • manual-override: if the failure is not related to a given PR
      • ib-failure: if the failure also happens in IBs
      • external-failure: if the failure is caused by external factor
    • ignore none: Do not ignore any tests results.
  • Enable extra PR tests: Anyone who can trigger tests can issue this command or use test parameters to enable some extra PR tests e.g.
    • enable gpu,threading,profiling,high_stats,nano: To run extra GPU, threading relval,profiling tests, high statistic relvals and/or nano tests.
    • enable profiling: To run Igprof and generate resource graphs
    • enable high_stats: To run high stats relvals tests
    • enable nano: To run tests for special nano workflows
    • enable hlt_p2_timing: To run HLT Phase2 Timing tests
    • enable none: To disable all extra tests
  • Allowing a user to trigger tests: L1/L2/Release managers can issue this command to give test triggering rights to a user for a specific pull request
    • allow @username test rights: Allows github user username to start the tests by using one of the please test commands.
