Subject Re: Apache MXNet build failures are mostly valid - verify beforemerge
Date Thu, 28 Sep 2017 06:19:44 GMT
Thank you for the clarification.

Agree force pushed are bad. I don't think anyone is doing this, though.

I am curious though, and this may be an unpopular question, but is there
precedent to tempoaraily disabling write access to people who merge in code
that hasn't passed CI tests and thus break CI (is there a way to tell)?
Certainly for 10% failures, one could argue that it "slipped by", but im
speaking more about blind merges that break everything 100% of the time.
How do other Apache projects deal with this?
