Module gc

This module provides access to the garbage collector for reference cycles.

enable() -- Enable automatic garbage collection. disable() -- Disable automatic garbage collection. isenabled() -- Returns true if automatic collection is enabled. collect() -- Do a full collection right now. get_count() -- Return the current collection counts. set_debug() -- Set debugging flags. get_debug() -- Get debugging flags. set_threshold() -- Set the collection thresholds. get_threshold() -- Return the current the collection thresholds. get_objects() -- Return a list of all objects tracked by the collector. get_referrers() -- Return the list of objects that refer to an object. get_referents() -- Return the list of objects that an object refers to.

Set the garbage collection debugging flags. Debugging information is
written to sys.stderr.
flags is an integer and can have the following bits turned on:
 DEBUG_STATS - Print statistics during collection.
 DEBUG_COLLECTABLE - Print collectable objects found.
 DEBUG_UNCOLLECTABLE - Print unreachable but uncollectable objects found.
 DEBUG_INSTANCES - Print instance objects.
 DEBUG_OBJECTS - Print objects other than instances.
 DEBUG_SAVEALL - Save objects to gc.garbage rather than freeing them.
 DEBUG_LEAK - Debug leaking programs (everything but STATS).
