  17 // When running with ThreadSanitizer, we need to explicitly set some
  18 // options specific to our codebase to prevent errors during runtime.
  19 // To override these, set the TSAN_OPTIONS environment variable.
  20 //
  21 // Currently, these are:
  22 //
  23 //   abort_on_error=1 - Causes TSan to abort instead of using exit().
  24 //   halt_on_error=1 - Causes TSan to stop on the first race detected.
  25 //
  26 //   report_signal_unsafe=0 - Required to avoid TSan deadlocks when
  27 //   receiving external signals (e.g. SIGINT manually on console).
  28 //
  29 //   allocator_may_return_null=1 - Tell TSan to return NULL when an allocation
  30 //   fails instead of aborting the program. This allows us to handle failing
  31 //   allocations the same way we would handle them with a regular allocator and
  32 //   also uncovers potential bugs that might occur in these situations.
