Bug 283086 – unsafe-merge-queue not rewriting "(OOPS!)" with "Originally-landed-as"

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Sam Sneddon [:gsnedders]]

Trying to land https://github.com/WebKit/WebKit/pull/36565, where the commit is applied from https://github.com/bugzilla/harmony/commit/effcc512d, albeit with a completely rewritten commit message, failed in the unsafe-merge-queue because it contained "(OOPS!)".

Notably, this ends with the trailer "Originally-landed-as: https://github.com/bugzilla/harmony/commit/effcc512d". Now, looking at Tools/Scripts/libraries/webkitscmpy/webkitscmpy/program/trace.py will tell you that this probably not the intended format of "Originally-landed-as", but it seemed not entirely silly. (AIUI, the intended semantic of "Originally-landed-as" is commits that don't _start_ on main (and are being merged to another branch, potentially main), but do start within the same commit graph.)

The only error https://ews-build.webkit.org/#/builders/22/builds/11808 gives is from validate-commit-message, "Commit message contains (OOPS!)".

With AddReviewerToCommitMessage having https://github.com/WebKit/WebKit/blob/e92bf171d84d991d69c755f872a08a3d1e13d2ed/Tools/CISupport/ews-build/steps.py#L6689-L6690:

```
    def hideStepIf(self, results, step):
        return not self.doStepIf(step)
```

There was nothing to indicate _why_ it hadn't added reviewers.

While this is potentially niche, given commits with Originally-landed-as have been disproportionately landed by Robert Jenner (60%) and Jonathan Bedard (34%), it nevertheless hides things that might be useful for the 6% of the time when other people make commits with Originally-landed-as trailers.
