The CI consolidation project adds more operating systems to Travis. This
refactoring is aimed to decouple the configuration of each individual OS
from the actual job matrix generation and formatting. Otherwise,
format_job function would turn into a huge collection of ad-hoc
conditions.
On OS X, "gcc" is really just clang anyways, so this combination gets tested by
the gcc test. This is purely redundant, and (since it runs early in the output)
increases time to signal for real breakages further down in the list.
This commit updates the gen_travis script with a new build bot
that covers the experimental `smallocx` API and updates the
travis CI script to test this API under travis.
This commit adds two build-bots to CI that test the release builds
of jemalloc on linux and macOS under valgrind.
The macOS build is not enabled because valgrind reports
errors about reads of uninitialized memory in some tests and
segfaults in others.
This commits checks on Travis-CI that the current `.travis.yml` file
equals the output of the `gen_travis.py` script, and updated
the `.travis.yml` file accordingly.
Add testing for background_thread:true, and condition a xallocx() -->
rallocx() escalation assertion to allow for spurious in-place rallocx()
following xallocx() failure.
Generalize the run_tests.sh and .travis.yml test generation to handle
combinations of arguments to the --with-malloc-conf configure option,
and merge "dss:primary" into the existing "tcache:false" testing.
Simplify configuration by removing the --disable-tcache option, but
replace the testing for that configuration with
--with-malloc-conf=tcache:false.
Fix the thread.arena and thread.tcache.flush mallctls to work correctly
if tcache is disabled.
This partially resolves#580.
Introduces gen_travis.py, which generates .travis.yml, and updates .travis.yml
to be the generated version.
The travis build matrix approach doesn't play well with mixing and matching
various different environment settings, so we generate every build explicitly,
rather than letting them do it for us.
To avoid abusing travis resources (and save us time waiting for CI results), we
don't test every possible combination of options; we only check up to 2 unusual
settings at a time.
