small valgrind test fixes #1941

merged 3 commits into from Jan 22, 2019

commented Jan 21, 2019

This PR makes 2 small improvements to the valgrind sharness test:

  • Run valgrind on an instance of size=2 instead of just a single broker. Some code in Flux is only active on rank > 0, so this will help find leaks and errors in those code paths.
  • The ignored errors from the underlying workload scripts. Log an error on non-zero exit code from any one of these scripts and cause a test failure.

This PR will fail until #1940 is addressed.

Problem: The valgrind workoad script does not exit with error
if one of the workload scripts gets an error during execution
or fails to execute.

Emit an error on non-zero exit code from the workload scripts,
and ensure that the valgrind test itself fails on error from any
script, instead of exiting with success.

Ensure at least some code for rank > 0 is run in the valgrind test
by executing multiple brokers instead of just a single broker in

Default size of test is 2 brokers, may be overidden by

In the case of running many brokers, the shutdown grace period may
need to be increased as well, so allow a VALGRIND_SHUTDOWN_GRACE
environment variable to do that (default=16s).
Now that the valgrind test runs more than a single broker, wreck
jobs take significantly longer to run. 10 jobs is probably overkill
anyway, so decrease it to 5 by default.

Rebased. I also made a couple other changes & cleanup:

  • change test string to reflect the real number of brokers in the instance being tested
  • decrease the number of wreck jobs run from 5 to 10
  • allow the size of the instance and grace time to be modified via environment variables ($VALGRIND_NBROKERS and $VALGRIND_SHUTDOWN_GRACE)
