Commit Queue Requirements:

• This PR addresses a relevant WM issue (if not, create an issue).
• All subcomponent pull requests (if any) have been reviewed by their code managers.
• Run the full Intel+GNU RT suite (compared to current baselines), preferably on Ursa (Derecho or Hercules are acceptable alternatives). Exceptions: documentation-only PRs, CI-only PRs, etc.
  • Commit log file w/full results from RT suite run (if applicable).
  • Verify that test_changes.list indicates which tests, if any, are changed by this PR. Commit test_changes.list, even if it is empty.
• Fill out all sections of this template.

Description:

[WORK IN PROGRESS]

• This PR will be testing along side the current PR process to see what other changes might be needed over the course of a month. Questions might need to be answered on how long we can keep this method up until we need to delete older baselines, and how that might work.

[WORK IN PROGRESS]

The current system of storage for baselines will copy/mv all baselines into a new bl_date regardless if the test changed baselines. This causes a lot of overlap between PR's that only change a few tests.

The work in this PR is meant to add a new function to the rt.sh called "Final Testing" which will add the '-f' option.

This -f option will make changes to the repository in tests/tests (where the bl_date will now be stored). This move will allow rt.sh to have a unique bl_date for every test. The -f option will also create the log file, and test_changes.list

I would recommend all PR's now use this -f option after a PR meets all criteria (minus what we would typically ask for in final testing, i.e. logs & test_changes.list) and it is ready for final testing. Then we will have the PR author run final testing as a final step before getting into the commit queue.
