[Qemu-devel] [PATCH v2 0/5] travis: reduce the matrix, add OSX, speed-up builds

[Alex Bennée]

Here is v2. I've added two new patches, a tweak to configure to accept
stems for target lists and then using that to cut the build time where
it makes sense. There has been a little tweak to the OSX build and
finally I've added r-b tags to the collapse and j3 patches.

Alex Bennée (5):
  .travis.yml: collapse the test matrix
  .travis.yml: enable OSX builds
  .travis.yml: make -j3
  ./configure: accept stems to match a range of targets
  .travis.yml: reduce target list on core configure tweaks

[Qemu-devel] [PATCH v2 1/5] .travis.yml: collapse the test matrix

[Alex Bennée]

Remove the concept of TARGETS and build the complete target list for
each config combination. Now the matrix is just based on CONFIG stanzas
and we use the additional stuff for:

  - things that only work on one compiler (sparse, gcov, gprof)
  - combos where "make check" fails

[Qemu-devel] [PATCH v2 2/5] .travis.yml: enable OSX builds

[Alex Bennée]

Travis has support for OSX builds. Making the setup work cleanly
involves a little hacking about with the .travis.yml file but rather
than make it too messy I've pushed all the "brew" install stuff into a
support script called ./scripts/macosx-brew.sh.

Currently only the default ./configure ${CONFIG} is built as I'm not
sure what extra coverage would come from the other build stanzas.

[Qemu-devel] [PATCH v2 3/5] .travis.yml: make -j3

[Alex Bennée]

The move from Travis VMs to Containers came with a upgrade from 1.5
cores to 2. The received wisdom is -j N+1 means a core can be doing work
while other threads wait for IO to complete. This is hard to test on the
Travis infrastructure but an initial before/after eyeballing seems to
confirm it is an improvement.

This is useful if you want to build all targets of a given architecture
or type. A simple submatch to an real target will add it to the list.

[Qemu-devel] [PATCH v2 5/5] .travis.yml: reduce target list on core configure tweaks

[Alex Bennée]

A number of configure options only really affect the core code and any
arch specific stuff should be flushed out by other builds:

  - trace-backends, log build is all targets, others can be less
  - --disable-build, ensuring disabling stuff doesn't break host
  - co-routine, default already built with all, common API
  - tcg interpreter is front end agnostic

I've used the ./configure --target-list stem support to do all of one
arch type in each reduced build.

AFAICT compiling extra targets is very unlikely to detect extra
problems with those config options.

Maybe we'd better require user to specify the exact glob patterns in
'--target-list' to avoid possible misuse?

Don't you run into problems of escaping glob patterns from the shell and
the like? For example if I do:

12:04 alex@zen/x86_64  [qemu.git/mttcg/base-patches-v2] >./configure
--target-list=arm*

ERROR: Unknown target name 'arm-softmmu-config-devices.mak.d'

As the shell picks up file names from the src dir.

Of course, it would be necessary to quote it like this:

    ./configure --target-list='arm*'
