# Turn on/off debug mode (off by default).
#
# Debug mode disables compiler optimizations and
# adds debugging metadata.
DEBUG =

# Turn on/off the debug locks (off by default).
#
# If enabled, the lock free structures will use a traditional
# lock (a mutex). This makes easier to debug problems when the
# issue is in a atomic operation or memory reorder.
LOCK =

# Turn on/off the trace mode (off by default).
#
# If enabled, a global and shared ring buffer is created and
# different part of the system will log to it atomically (but
# see the limitations in the code).
# Use this for debugging and introspection.
TRACE =

# Turn on/off the sanitization mode. (off by default).
# This modes relays in the compiler's
# ability to instrument the code to detect race conditions in runtime.
# It makes the program between 5 and 15 times slower (and consumes around
# 15 times more memory)
# Makes sense to use this only for testing and with DEBUG turned off.
