[libc] fixed signed char issues in strsep()/strtok()/strtok_r(). (#156705)

2025-09-03T18:00:38+00:00

Also add the missing tests for all the related functions (even the ones
that were already right), and add the missing bazel build rules.

[libc] fix strsep()/strtok()/strtok_r() "subsequent searches" behavior. (#154370)

2025-08-21T13:32:35+00:00

These functions turned out to have the same bug that was in wcstok()
(fixed by 4fc9801), so add the missing tests and fix the code in a way
that matches wcstok().

Also fix incorrect test expectations in existing tests.

Also update the BUILD.bazel files to actually build the strsep() test.

[libc] Don't rely on LIBC_HAS_SANITIZER when enabling null checks. (#150341)

2025-07-24T21:15:46+00:00

LIBC_HAS_SANITIZER (which is defined if ASan, MSan, or UBSan is enabled)
is currently used to implicitly disable null checks, normally enabled
via LIBC_ADD_NULL_CHECKS config value. Remove this condition, and rely
purely on the config value instead:

* LIBC_HAS_SANITIZER will be true even for UBSan modes which doesn't
rely on null checks at all (e.g. -fsanitize=alignment)
* null checks today (implemented via __builtin_trap) should function
normally today even when sanitizer is enabled - trap is still a trap
* tests have been migrated to WITH_SIGNAL(-1) which doesn't prescript a
particular signal / exit-code, and thus should pass even if sanitizers
override the default ones.

[libc] Expand usage of libc null checks. (#116262)

2025-06-04T17:08:27+00:00

Fixes #111546
