# Sanitizer / dynamic-analysis configurations.

# Pick one with `--config=<name>`, e.g.
#     bazel test --config=asan     //toolbelt:sockets_test
#     bazel test --config=tsan     //toolbelt:sockets_test

# All three configs preserve debug information so failures point back to

# Valgrind.  Runs the unmodified binary under Memcheck.
#
# Notes:
#   * Valgrind is not available on macOS arm64.  Use Linux (or x86_64) to
#     exercise this config.
#   * --error-exitcode=1 makes the test fail on any reported error.
#   * --child-silent-after-fork=yes suppresses noise from forking helpers.
