2017-12-21[sanitizer] Make function declarations C-compatiblePetr Hosek
The public sanitizer headers are intended to be usable from either C++ or C, but they declare no-argument functions with the syntax that is not a proper prototype declaration in C. This goes unnoticed until someone uses -Wsystem-headers.

2017-09-08Prevent DCE on __lsan_is_turned_off and re-enable test caseFrancis Ricci
Summary: -dead_strip in ld64 strips weak interface symbols, which I believe is most likely the cause of this test failure. Re-enable after marking the interface function as used.

2015-08-21[Sanitizers] Unify the semantics and usage of "exitcode" runtime flag across ↵Alexey Samsonov
all sanitizers. Summary: Merge "exitcode" flag from ASan, LSan, TSan and "exit_code" from MSan into one entity. Additionally, make sure sanitizer_common now uses the value of common_flags()->exitcode when dying on error, so that this flag will automatically work for other sanitizers (UBSan and DFSan) as well. User-visible changes: * "exit_code" MSan runtime flag is now deprecated. If explicitly specified, this flag will take precedence over "exitcode". The users are encouraged to migrate to the new version. * __asan_set_error_exit_code() and __msan_set_exit_code() functions are removed. With few exceptions, we don't support changing runtime flags during program execution - we can't make them thread-safe. The users should use __sanitizer_set_death_callback() that would call _exit() with proper exit code instead. * Plugin tools (LSan and UBSan) now inherit the exit code of the parent tool. In particular, this means that ASan would now crash the program with exit code "1" instead of "23" if it detects leaks.

2015-04-24[lsan] Add an interface function for on-demand leak checking.Sergey Matveev
Summary: Add an interface function which can be used to periodically trigger leak detection in a long-running process. NB: The meaning of the kIgnored tag has been changed to allow easy clean-up between subsequent leak checks. Previously, this tag was applied to explicitly ignored (i.e. with __lsan_disable() or __lsan_ignore_object()) chunks *and* any chunks only reachable from those. With this change, it's only applied to explicitly ignored chunks.
