[Qemu-devel] [PATCH v1 0/8] Travis stability and a few docker patches

[Alex Bennée]

Hi,

Again the final patch won't make it into a pull-request but I'm just
keeping it around to keep track of failures. So far my numerous
re-builds have been mainly plain timeouts.

The alternate co-routine builds are sailing the closest to timeout
purgatory which makes me think we should limit the scope of the
testing - I'm not sure how much of the unit tests or qapi tests are
likely to exercise the co-routine code. Is it likely only the
(currently not run) block tests really exercise this area of code?

I've also updated the Travis image to be more recent. I noticed while
doing so that the Travis clang was newer than our hand crafted tools
so I took the opportunity to drop them and just concentrate on
exercising the python stuff. It might be worth just limiting the
target list for those tests to x86_64 only though?

There are also a couple of Philippe's patches which I should have
queued ages ago. If we get some quick reviews I can turn around a pull
request by the end of the week.

[Qemu-devel] [PATCH v1 1/8] .travis.yml: disable linux-user build for gcov

[Alex Bennée]

Currently the default testing doesn't exercise the linux-user builds
so there is no point spending time building them. We may want to
enable a separate gcov build once linux-user testing is re-enabled
although it's likely to report very low coverage.

[Qemu-devel] [PATCH v1 4/8] docker: update Travis docker image

[Alex Bennée]

This is still poorly documented by Travis but according to:

  https://docs.travis-ci.com/user/common-build-problems/#Running-a-Container-Based-Docker-Image-Locally

their reference images are now hosted on Docker Hub. So we update the
FROM line to refer to the new default image. We also need a few
additional tweaks:

  - re-enable deb-src lines for our build-dep install
  - add explicit PATH definition for tools
  - force the build USER to be Travis
  - add clang to FEATURES for our test-clang machinery

I don't understand how this is related to QEMU testing, isn't it rather
some Travis-ci bug? We don't need to use PhantomJS / Neo4j / Maven.

It's oddly constructed I'll grant you but I just set the path to what a
running image has. The normal image is started up with a full systemd
init whereas we drop directly into the shell.

OK, can you add a comment about it? (so we don't remove what seems
unrelated).

[Qemu-devel] [PATCH v1 5/8] .travis.yml: rationalise clang testing

[Alex Bennée]

As Travis includes Clang 5.0 in its own build environment there is no
point manually building with older Clangs. We still need to test with
the two pythons though so we leave them as system only builds. We also
split the clang build into two as it often exceeds the 40 minute build
time limit.

[Qemu-devel] [PATCH v1 6/8] .travis.yml: make current setup explicit

[Alex Bennée]

Add some commentary and make the selection of Container based Trusty
build explicit. We will need to add VM builds later when using docker.

[Qemu-devel] [PATCH v1 7/8] .travis.yml: update GCC sanitizer build to GCC 7

[Alex Bennée]

GCC has moved on and so should we. We also enable apt update to ensure
we get the latest build from the toolchain PPA.

[Qemu-devel] [PATCH v1 8/8] tests/Makefile: mark flakey tests (!UPSTREAM)

[Alex Bennée]

This is a bookmarking commit to keep track of the failures I'm
currently seeing in Travis. They are currently:

1. test-aio

GTESTER tests/test-thread-pool
**
ERROR:tests/test-aio.c:501:test_timer_schedule: assertion failed: (aio_poll(ctx, true))
GTester: last random seed: R02S66126aca97f9606b33e5d7be7fc9b625
make: *** [check-tests/test-aio] Error 1
make: *** Waiting for unfinished jobs....

Last discussion @ 20180525091724.GC14757@stefanha-x1.localdomain

  - rcutorture

[AWAITING EXAMPLE]

I suspect it is load that causes the problems but they really need to
be fixed properly.
