[Swift CI] Build Still Failing: 0. OSS - Swift Incremental RA - Ubuntu 16.04 (swift 4.0) #449


(Michael Ilseman) #1

(going out on a limb here) Pushkar, does this look familiar to you? It seems to be failing right when trying a URLSession test case. I’m otherwise not sure what could be the cause, as the blamelist doesn’t look related.

(Pushkar N Kulkarni) #2

We’ve never seen this failure, but I can’t rule out the possibility of this originating in the URLSession tests. Though 2 out of 13 CI builds failed in URLSession yesterday, these failures are really intermittent. I am unable to reproduce them locally even after running TestFoundation in a loop for a couple of thousand times.

Nevertheless, I am turning off the tests again until we have more clarity on what’s happening here. Thanks.

It looks like the crash that we saw is this dispatch one: https://bugs.swift.org/browse/SR-4677

I haven’t seen any other crash over 20K runs of TestNSURLSession locally. I have a PR with the tests disabled again.
