[CI Problem] CI-arm build queue blocked about tvm HOT 5 CLOSED

Hi @Lunderberg, I too would have expected that only the last commit on the rebased branch would have been built. Really seems odd that this isn't the default behaviour here.

Thanks for looking in to it and getting the queue moving again. I agree that setting the Jenkins option disableConcurrentBuilds(abortPrevious: true) sounds like a sensible idea. For now, I am happy to close this issue as resolved.

Huh, that definitely wasn't intended with that PR. The large number of commits was due to rebasing onto main, where I had expected that only the last commit on the rebased branch would be built, as the intermediate commits don't require testing.

This PR is also one that impacts packed_func.h, which is included by practically everything in TVM. So, not only is it re-building TVM once for each rebased commit, but they're also full rebuilds that can't benefit from ccache.

Short-term, I've stopped all tasks related to #16183, and the ARM queue is recovering. All remaining tasks are related to other PRs, as it works through the backlog.

Long-term, it looks like there's a Jenkins option disableConcurrentBuilds(abortPrevious: true) (stack overflow link, GH link)) that we should enable. If there's two concurrent builds for the same PR, it would cancel the previous one.

This issue also seems to have occurred on #16425
