[DragonFlyBSD - Bug #3183] (Closed) Go builder: failures connecting to locally created webservice during build tests

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3183 has been updated by t_dfbsd.

Status changed from New to Closed

Closing this ticket. The Go team found a bug in the crypto/tls build test. From comments:

"crypto/tls: deflake localPipe in tests

The localPipe implementation assumes that every successful net.Dial
results in exactly one successful listener.Accept. I don't believe this
is guaranteed by essentially any operating system. For this test, we're
seeing flakes on dragonfly (#29583)."

I don't understand why Dragonfly was hitting this bug so often, whereas I don't recall seeing it on OpenBSD or NetBSD. In any case, it's fixed.

----------------------------------------
The Dragonfly builder for Go reports frequent, but random failures in the crypto/tls test. The root cause seems to be an inability to connect to the local webservice created during the test. This feels kind of race-y to me and I don't see any of the other builders experiencing the problem. I don't know enough to say whether it's a Go issue or a Dragonfly issue. An example of this is:
