Remove pending builds from buildbot?

[Chris Jones]

Normally making a commit that does not change the revision or version will not trigger a rebuild, assuming the previous port revision built OK on a given platform. If this is the case then again the builds do not need to be cancelled. If the previous builds in fact did not build, then yes another rebuild will be attempted, so if nothing has changed to fix the previous build failure it will fail again. If this is the case then its best not avoid making such commits until you are able to do so at the same times as fixing the build failures. If this cannot be done the the port should use the known_fail pattern for the OSes known to fail, to avoid needless failing rebuilds.

Since there's such a long queue on the 10.13 and 12 builders, I'm thinking that cancelling a fairly length build that isn't needed would help clear up the backlog a bit faster. If there's an easy way to cancel the build on all of the builders (not just 10.13 and 12), that would probably be even better. On the other hand, if cancelling the build would be a hassle, then don't worry about it.
