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.
get_stats() -- Return list of dictionaries containing per-generation stats.
set_debug() -- Set debugging flags.
get_debug() -- Get debugging flags.
set_threshold() -- Set the collection thresholds.
get_threshold() -- Return the current collection thresholds.
get_objects() -- Return a list of all objects tracked by the collector.
is_tracked() -- Returns true if a given object is tracked.
is_finalized() -- Returns true if a given object has been already finalized.
get_referrers() -- Return the list of objects that refer to an object.
get_referents() -- Return the list of objects that an object refers to.
freeze() -- Freeze all tracked objects and ignore them for future collections.
unfreeze() -- Unfreeze all objects in the permanent generation.
get_freeze_count() -- Return the number of objects in the permanent generation.

Symbols in gc

c

callbacks: A list of callbacks that will be invoked by the garbage collector before and after collection.
collect: Run the garbage collector.

d

DEBUG_COLLECTABLE: Print information on collectable objects found.
DEBUG_LEAK: The debugging flags necessary for the collector to print information about a leaking program (equal to DEBUG_COLLECTABLE | DEBUG_UNCOLLECTABLE | DEBUG_SAVEALL).
DEBUG_SAVEALL: When set, all unreachable objects found will be appended to garbage rather than being freed.
DEBUG_STATS: Print statistics during collection.
DEBUG_UNCOLLECTABLE: Print information of uncollectable objects found (objects which are not reachable but cannot be freed by the collector).
disable: Disable automatic garbage collection.

e

enable: Enable automatic garbage collection.

f

freeze: Freeze all current tracked objects and ignore them for future collections.

g

garbage: A list of objects which the collector found to be unreachable but could not be freed (uncollectable objects).
get_count: Return a three-tuple of the current collection counts.
get_debug: Get the garbage collection debugging flags.
get_freeze_count: Return the number of objects in the permanent generation.
get_objects: Return a list of objects tracked by the collector (excluding the list returned).
get_referents: Return the list of objects that are directly referred to by 'objs'.
get_referrers: Return the list of objects that directly refer to any of 'objs'.
get_stats: Return a list of dictionaries containing per-generation statistics.
get_threshold: Return the current collection thresholds.

i

is_finalized: Returns true if the object has been already finalized by the GC.
is_tracked: Returns true if the object is tracked by the garbage collector.
isenabled: Returns true if automatic garbage collection is enabled.

s

set_debug: Set the garbage collection debugging flags.
set_threshold: Set the collection thresholds (the collection frequency).

u

unfreeze: Unfreeze all objects in the permanent generation.
