These patches try to improve our Travis CI usage (quite a few failures the last
days).

This series include Peter's "Automate coverity scan uploads via Travis"
patches (here numbered 3 to 6). See
https://www.mail-archive.com/qemu-devel@nongnu.org/msg457443.html

Patch 7 is expected to enter /master as of today.
Travis warned few months ago:
  "On Wednesday, June 21st 2017, we are going to update all our Ubuntu Trusty
  14.04 images."

Patches 2, 10 and 15 use 'travis_retry' feature to avoid aborting a job on
network failure, retrying 3 times (default).

Patches 8, 19 are upgrades allowing to use recent VMs/toolchains.

Patch 12 speed up builds using multicore parallelism, caring about not overkill
Travis hardware.

Patches 9, 11, 13, 17 speed up builds improving cache usage.

Patches 18, 21 silent warnings.

Patch 14 gives hint when ./configure fails.

Patch 16 split slow gprof/gcov job.

Finally patch 1 add a missing rule to build system-qemu binary before running
qtests.

time comparison:
----------------

current /master https://travis-ci.org/qemu/qemu/builds/245061137:

This allow a one liner from fresh repository clone, i.e.:

  ./configure && make -j check-qtest-aarch64

TIL -j doesn't need a number and GNU Make has a -l option ;-)

Also since 2.8 (2016) git fetch has -j option, but Travis is using a 
release version 1.8 (from the git-core PPA)

on my debian/unstable git version 2.13.1 I can do:

  $ git submodule update --init --recursive --depth 1 -j ${PARALLEL_JOBS}

I'm on board, it's nice to have proper dependencies.

Update the travis list of library packages to install so that
our build tests cover more of our code base.

Add a new script to automate the process of running the Coverity
Scan build tools and uploading the resulting tarball to the
website. This is primarily intended to be driven from Travis,
but it can be run locally (if you are a maintainer of the
QEMU project on the Coverity Scan website and have the secret
upload token).

Add config to travis to do a Coverity Scan build and upload, using
the new run-coverity-scan script.

There is an official integration between Travis and Coverity Scan:
 https://github.com/travis-ci/travis-build/blob/master/lib/travis/build/addons/coverity_scan.rb
which slurps values out of the .travis.yml and downloads a build
script from Coverity which does the bulk of the work:
 https://scan.coverity.com/scripts/travisci_build_coverity_scan.sh

However we choose to roll our own since this seems less
confusing and also allows us to include debug features
(notably the ability to do a "dry run" test which doesn't
actually upload anything).

I think this is waiting on a fix I mention when reviewing Peter's
original patches.

Ok! I'll wait or drop the Coverity part.

The way I read that blog post is group: edge is for testing things still
work but you probably don't want to merge that into your master branch.
Otherwise we'll automatically be running the bleeding edge.

Ok I misunderstood this part, good you noticed.

Travis team posted a new entry after which is clearer:
https://blog.travis-ci.com/2017-06-21-trusty-updates-2017-Q2-launch

I'm now using "group: deprecated-2017Q2" instead of "edge".

I wonder if we could replace our submodule pre-seed hack with a native
Travis version? And now I see you do that in a later patch ;-)

Travis caching uses the branch name to store packed cache, so each new branch
will trigger a cache miss and will clone all submodules. Subsequent builds will
benefit from the cache.

Hmmm looking deeper it doesn't look as though we are benefiting from the
caching here. The submodule checkout is around 60-70s with some jobs
coming down to 30-40s. The old system seems to be ~20s for the
wget/checkout step (assuming the wget is cached).

Few improvement as of today, but if Travis release their limit on the opensource
plan or upgrade their hardware, new builds will get some benefit.

Restrict to as most 4 cores to respect Travis Open Source plan.

You need to mention you are also enabling a parallel make check here.

Can you expand the commit message to breifly explain what all these
extra settings change. What is CCACHE_SLOPINESS and ccache -s doing?

Does this actually have any effect?  We should not be using time macros.

include_file_ctime/mtime makes sense though.

Won't the explicit || mean the job will keep trying even if config is
broken? Should it be || cat config.log && false?

Yes, you right. I actually copied it from the "Trusty build with latest 
stable clang" job from commit ae1a772c :p

I'll see to fix other occurrences.

Mmm, I've been vaguely wondering what to do about those warnings
for a while. The difficulty is that applying -Wno-deprecated-declarations
silences all deprecation warnings, not just the SASL ones, so we
lose a bit of warning coverage. Maybe that's just a hit we have
to take, though.

thanks

Hmm, does clang understand "#pragma GCC diagnostic" ?

If so, then this can be done in in the code not the makefiles, and also
selectively for osx only.

See include/ui/gtk.h for an example.

cheers,

It does have some diagnostic pragma support. The awkward part is
that it has to  be in force at the point where the deprecated
function is used, not where it's declared. So you can't just wrap
the #include of the ssl header in pragmas, you'd have to either
do it at every callsite or else over the whole .c file.

thanks

Do it on the whole file on osx only is still better because we continue
to get the warnings on non-osx then, which should be enough to avoid
the code bitroting unnoticed.
