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.
Rather than relying on parallel make to build individual configurations
one at a time, use xargs to build multiple configurations in parallel.
This allows the configure scripts to run in parallel. On a 14-core
system (28 hyperthreads), this increases average CPU utilization from
~20% to ~90%.
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.
In 6e7d0890 we added better travis continuous integration tests. This is nice,
but has two problems:
- We run only a subset of interesting tests.
- The travis builds can take hours to give us back results (especially on OS X).
This adds scripts/gen_run_tests.py, and its output, run_tests.sh, which builds
and runs a larger portion of possible configurations on the local machine.
While a travis run takes several hours to complete , I can run these scripts on
my (OS X) latop and (Linux) devserve, and get a more exhaustive set of results
back in around 10 minutes.
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.
