no-lto: true # While MSAN might work with LTO, I do not want the aggravation/entropy. Turn it off.
# We concentrate on clang sanitizers; they are newer/nicer; also MSAN is clang-only. So gcc ones excluded.
# Attention! Excluding some sanitizer job(s) (with these reasons):
# - MSAN: MSAN protects against reads of ununitialized memory; it is clang-only (not gcc), unlike the other
# *SAN. Its mission overlaps at least partially with UBSAN's; for example for sure there were a couple of
# uninitialized reads in test code which UBSAN caught. Its current state -- if not excluded -- is as
# follows: 1, due to (as of this writing) building dependencies, including the capnp compiler binary used
# during our build process, with the same compiler build config as the real code, ignore-list entires had
# to be added to get past these problems. 2, before main() in *all* our demos/tests Boost was doing some
# global init which MSAN did not like and hence aborted before main(); these are now ignored as well.
# 3, this got us into main() at least, but immediately cryptic aborts started, seemingly again originating
# in Boost (but requires detailed investigation to really understand). At this point I (ygoldfel)
# disabled MSAN and filed a ticket. The overall status: MSAN is said to be useful, even with UBSAN active,
# but all resources including official docs indicate that it is a high-maintenance tool:
# *All* linked code, including libc and libstdc++/libc++ (the former in our case as of this writing),
# must be instrumented to avoid cryptic false positives. The good news is we do build other things
# instrumented (Boost libs, jemalloc, capnp/kj, gtest); but not libstdc++ (which official docs recommend);
# this can be done but requires more work (I would suggest switching to libc++ in that case from the
# start, as the clang people made it and themselves build it instrumented for their testing).
# So the bottom line: MSAN is a tough cookie and requires more work before enabling. In the meantime we
# have many layers of protection, including ASAN and UBSAN and lots of unit and integration tests.
# So this status quo is pretty good. TODO: Do the work/get MSAN functional/useful; un-exclude it then.
# - *SAN with gcc: We concentrate on clang sanitizers; they are newer/nicer; having to worry about differences
# between them is an excessive burden. So excluding gcc ASAN/UBSAN/TSAN.
# - TODO: Consider reducing to the newest clang. Generally they just keep improving; the chances of
# something being uncaught (incorrectly) with a later version are slim. Not impossible though. Look
# into it.

# Run-time controls for various sanitizers. Some notes:
#
# Unclear if we need disable_coredump=0; it might be a gcc thing due to historic
# issues with core size with ASAN; it is not documented in the clang *SAN docs for any
# sanitizers; but it is accepted for ASAN and TSAN, seemingly, and maybe is at worst
# harmless with out compiler versions. TODO: Maybe revisit.
#
# print_stacktrace=1 for UBSAN is recommended by documentation for nice stack traces
# (also that is why we apply sanitizers to RelWithDebInfo; DebInfo part for the nice
# stack traces/etc.; Rel part to reduce the considerable slowdown from some of the
# sanitizers).
#
# second_deadlock_stack=1 for TSAN: TODO: Explain. Don't see it in clang TSAN docs.
#
# Caution! Setting multiple *SAN_OPTIONS (while invoking only 1 sanitizer, as we do)
# seems like it would be harmless and avoid the `if/elif`s... but is actually a
# nightmare; there is some interaction in clang (at least 13-17) which causes the
# wrong sanitizer reading suppressions from another one => suppression parse error =>
# none of the demos/tests get anywhere at all. So set just the right one!

# We need to prepare a sanitizer ignore-list in MSAN mode. Background for this is subtle and annoying:
# As it stands, whatever matrix compiler/build-type is chosen applies not just to our code (correct)
# and 3rd party libraries we link like lib{boost_*|capnp|kj|jemalloc} (semi-optional but good) but also
# unfortunately any items built from source during "Install Flow-IPC dependencies" step that we then
# use during during the build step for our own code subsequently. At a minimum this will slow down
# such programs. (For the time being we accept this as not-so-bad; to target this config at some things
# but not others is hard/a ticket.) In particular, though, the capnp compiler binary is built this way;
# and our "Build targets" step uses it to build key things (namely convert .capnp schemas into .c++
# and .h sources which are then themselves compiled/used in compilation). In the case of MSAN, this
# version of capnp compiler happens to trigger several MSAN failures (presumably they are not a true
# problem, and it's not our job really to sanitize capnp -- though we can file tickets for them and/or
# issue PRs; but I digress). So in MSAN mode our build step fails, when capnp compiler itself aborts
# with MSAN failures. One approach is to not apply MSAN to capnp compiler (no-go for now; it's a ticket
# as mentioned); another is to uses Conan to patch capnp package for them (not a bad idea; ticket filed);
# and lastly we can put the specific failures on the ignore-list for MSAN. For now we do that; while
# unpleasant it does get the job done. TODO: Revisit/resolve tickets/improve (see above).

# to begin-with, this is a no-brainer. For those (as of this writing the main one
# is unit_test; but also the link tests produce short logs too) who use stdout/stderr
# the reason to do this is 2-fold.
# - UBSAN in particular produces non-fatal error output about problems it detects.
# We need to analyze them after the fact and fail a step below in that case to
# alert developers who would then fix such new problems.
# - One can also build UBSAN-mode things with -fno-sanitize-recover which would
# cause abnormal program exit on *first* error. We do not do this for these
# reasons:
# - It is more convenient to let it continue and thus show all problems in one
# shot.
# - There is a side problem: At this time compile settings, including
# in UBSAN case `-fsanitize=undefined -fno-sanitize-recover`, are applied not
# just to our code or 3rd party libraries but also any other stuff built
# (due to setting C[XX]FLAGS in Conan profile). Targeting just the exact
# stuff we want with those is hard and a separate project/ticket.
# In the meantime -fno-sanitize-recover causes completely unrealted program
# halts during the very-early step, when building dependencies including
# capnp; some autotools configure.sh fails crazily, and nothing can work
# from that point on due to dependencies-install step failing. So at this
# time -fno-sanitize-recover is a no-go; it affects too much unrelated stuff.
# - It is more consistent/convenient to get all the bulky logs in one place as an
# artifact, rather than some in the pipeline output, others in the artifacts.
# (This preference is subjective, yes.)
