Andrei Sekretenko created MESOS-10105:
-----------------------------------------
Summary: Make tests of builds with
-fsanitize=address/memory/undefined/thread pass.
Key: MESOS-10105
URL: https://issues.apache.org/jira/browse/MESOS-10105
Project: Mesos
Issue Type: Wish
Reporter: Andrei Sekretenko
As exemplified by various C++ projects and also by targeting specific issues in
Mesos (for example, MESOS-10102), running code built with clang sanitizers
helps with uncovering undefined behavior and data races.
Sanitizer adoption usually happens as a sequence of steps which unblock each
other:
1) making local tests pass under sanitizer at least once
2) making CI regularly run sanitizer builds (so that new sanitizable bugs are
not introduced and more bugs not triggered deterministically are uncovered)
3) running high-level integration tests, betas, etc. with sanitizer builds
--
(3) is definitely out of scope of this wish, and it is not clear if (2) will
fit into ASF CI, but (1) is definitely doable, and on its own can lead to
figuring out causes of mysterious rare bugs (which might turn out to be not so
rare under certain conditions).

State of Mesos w.r.t sanitizers:
- as of Mar 2020, Mesos tests built with -fsanitize=address crash due to
several locations that leak one object per thread lifetime
- as of Nov 2019, libprocess tests were crashing thread sanitizer; IIRC, the
issues in libprocess on Linux/amd64 are also "technical", but probably could
result in a very real problems on a different platform
