tox: *-asan: Activate LeakSanitizer on recent CPython 3
Browse files Browse the repository at this point in the history 
Background: in 2019 in 4dc1a7f0 (tox += ThreadSanitizer, AddressSanitizer,
Python debug builds) I've added ThreadSanitizer and AddressSanitizer to our
test build matrix. That was done in order to help catching concurrency issues
while doing quality assurance and it indeed worked well(*). However AddressSanitizer
was added with disabled memory leak detection, because at that time there were
tons of various allocations done by Python itself, that were not released on
Python shutdown. So leak reporting pass was disabled to avoid huge non-pygolang
related printouts.

5 years later Pygolang is used by various projects, including in XLTE, where, in
particular, it is used to organize 100Hz polling of Amarisoft eNodeB service to
retrieve information about flows on Data Radio Bearers:

https://lab.nexedi.com/kirr/xlte/-/commit/2a016d48
https://lab.nexedi.com/kirr/xlte/-/blob/8e606c64/amari/drb.py

And everything works relatively well except that recently Joanne approached me
with reports that xamari program, that does the polling, is leaking memory.

During investigation I could manually find at least two causes of the leakage,
and, while working on a fix, discovered third type of leak. Since all those
leaks happen inside Pygolang and at, or around, C level - most of the
time not visible through python objects and so not discoverable via e.g
objgraph, it raises the need to have robust quality assurance procedures
built into maintenance process to cover not only concurrency and memory
safety issues, but also to reliably detect low-level memory leaks.

So before we start fixing any of the leakages, let's activate LeakSanitizer
(https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer) to be
present during tox runs, so that whenever we run something via ASAN in the end
tested process is checked for whether anything was leaked and if yes, which
codepath was used to allocate leaked memory.

Initially I though that it would be hard to have distilled reports, the ones
without much of added noise due to leaks on python side, but it turns out that
starting from py3.11 cpython codebase was improved to release on interpreter
shutdown most of what was allocated, and so with modest suppression rules we
can distill LeakSanitizer output to come with the issues that are relevant to
pygolang itself.

That builds the foundation for making sure there are no memory leaks done by
pygolang in the follow-up patches. The next patch will fix chan leakage in
pychan_from_raw, and there will be more fixes to come later.

For now ASAN builds become broken, but that is good that we can see the issues.
Please see the appendix for current LeakSanitizer output.

(*) at that time, besides discovering longstanding race-condition in Python itself
(https://bugs.python.org/issue38106, https://github.com/python/cpython/pull/16047),
several concurrency issues were found in pygolang codebase as well:

# .lsan-ignore.txt lists memory leak events that LeakSanitizer should not
# report when running pygolang tests.
#
# Many python allocations, whose lifetime coincides with python interpreter
# lifetime, and which are not explicitly freed on python shutdown, are
# reported as leaks by default. Disable leak reporting for those to avoid
# non-pygolang related printouts.
