Hi Patrick Robb,

The behavior you describe is correct - when the rebase argument is used, the patch should be applied to HEAD of the branch specified by the rebase arg.

However, I do believe there is a discrepancy in our labs behavior when it comes to retests which are submitted without the rebase argument. In this case, UNH lab, AWS, and GitHub are running retests on the original patch artifacts without re-applying to the current HEAD at the time of the retest. On the other hand, I believe Loongson does re-apply to HEAD even when the rebase argument is not specified. I think in an ideal world our behavior would be uniform across the labs. What that would require in this case is either:

1. Loongson changes to retesting without re-apply on HEAD when no rebase argument is given (unclear how much work this is)

I'm glad to say Loongson lab has changed to retesting without re-apply on HEAD when no rebase argument is given. We recorded the commit ID of the base for the series to test during the first test and use it as the base to retest if no rebase argument is specified. We also ensure that the patch will be applied to HEAD of the branch specified by the rebase argument if it exists.
