Subject: [PATCH v3 0/4] test-lib: improve LSAN + ASAN stack traces
Date: Mon, 21 Feb 2022 16:58:31 +0100 [thread overview]
Message-ID: <cover-v3-0.4-00000000000-20220221T155656Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v2-0.4-00000000000-20220219T112653Z-avarab@gmail.com>
A UX improvement for [AL]SAN stack traces. See
https://lore.kernel.org/git/cover-v2-0.4-00000000000-20220219T112653Z-avarab@gmail.com/
for the v2.
Changes:
* Renamed GIT_XSAN_OPTIONS to GIT_SAN_OPTIONS per Junio's suggestion
* Fixed grammar ("do do do...")" in commit message.
Ævar Arnfjörð Bjarmason (4):
test-lib: add GIT_SAN_OPTIONS, inherit [AL]SAN_OPTIONS
test-lib: correct commentary on TEST_DIRECTORY overriding
test-lib: make $GIT_BUILD_DIR an absolute path
test-lib: add "fast_unwind_on_malloc=0" to LSAN_OPTIONS

- test-lib: add GIT_XSAN_OPTIONS, inherit [AL]SAN_OPTIONS
+ test-lib: add GIT_SAN_OPTIONS, inherit [AL]SAN_OPTIONS
Change our ASAN_OPTIONS and LSAN_OPTIONS to set defaults for those
variables, rather than punting out entirely if we already have them in
the environment.
- We do want to take any user-provided settings over our own, but we can
- do do that by prepending our defaults to the variable. The
- libsanitizer options parsing has "last option wins" semantics.
