[Bug 1567096] Comment bridged from LTC Bugzilla

[Michael Hudson-Doyle]

That's not really the sort of test I wanted; I want something I can
show to the SRU team that will motivate including Go 1.6.2 in Ubuntu
16.04. This bug was originally about docker not working, can you
provide reproduction steps for that?

As far as I can tell, everything in yakkety should be new enough to
run the golang-fsnotify tests, but they still fail on ppc64el for me
(TestInotifyRemoveTwice fails with "no error on removing invalid file"
and TestInotifyInnerMapLength hangs until the 10 minute timeout kills
it).

Cheers,
mwh

Title:
  Docker doesn't work since Containerd integration

Status in golang-1.6 package in Ubuntu:
  Fix Released

Bug description:
  -- Problem Description --
  Docker build hangs indefinitely when run using a 1.11.0 binary built after containerd integration, and go 1.6 on ppc64le. Doing the same thing works with gccgo.

  Looking at the differences in docker logs shows that the containerd
  event "exit", never happens when using a binary built with gc.
  fsnotify, the file system handler for go, doesn't seem to receive the
  correct event when a file is either written to, or closed, which I
  believe is whats causing this issue.

  Link to fsnotify issue which shows some failing tests :
  https://github.com/fsnotify/fsnotify/issues/130

  I have a patch that fixes the errors when I run fsnotify.  I am
  preparing it for submission now and should be out there as a golang CL
  this morning.

  Do you want the patch so you can rebuild golang with it?  If fsnotify
  is a separate package then you will have to rebuild it with the new
  golang.

  Here's the CL link if you want to get the patch for ppc64le:  https://go-review.googlesource.com/#/c/21582/
  Go to the upper right where it says download and I think if you select patch file it will give you the patch.

  We'll update with more info after testing the patch Lynn submitted,
  but we wanted to let Canonical know about this issue in the meantime
  since 1.11 is about to GA upstream.
