  Fix reporting errors with `gai_strerror(..)`

  The return value (`err`) should be checked; not the `errno` value.

Comment 2 Li-Wen Hsu freebsd_committer 2019-01-26 09:17:51 UTC
These tests still fail because the testing VM doesn't have Internet connection. I'll work on that.  In the meanwhile, do you think it's reasonable to mark these cases "skip" when there is no Internet connection or make it not depending on public Internet connection?

I opened up https://reviews.freebsd.org/D19026 to remove the DNS lookup piece, as it's not important to the overall test. I just wanted to avoid hardcoding the address (c'est la vie -- I didn't anticipate this... *shrugs*).

  Avoid the DNS lookup for "localhost"

  ci.FreeBSD.org does not have access to a DNS resolver/network (unlike my test
  VM), so in order for the test to pass on the host, it needs to avoid the DNS
  lookup by using the numeric host address representation.

After r343751, the cases in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235200#c0 is fixed but now we have lib.libc.sys.sendfile_test.hdtr_positive_v{4,6} failing.

Funny... I must have fixed some of the underlying issues in prior commits. Weird why it was failing for me on my host when testing out that commit. I'll try again :)!

Nope. Someone else must have fixed something... (this kernel is 4 days old)?

  Make `server_cat(..)` handle short receives

  In short, the prior code was far too simplistic when it came to calling recv(2)
  and failed intermittently (or in the case of Jenkins, deterministically).

  Handle short recv(2)s by checking the return code and incrementing the window
  into the buffer by the number of received bytes. If the number of received
  bytes <= 0, then bail out of the loop, and test the total number of received
  bytes vs the expected number of bytes sent for equality, and base whether or
  not the test passes/fails on that fact.

  Remove the expected failure, now that the hdtr testcases deterministically pass
  on my host after this change [1].
