class CheckContainers(name, leakDetector, index)[source]

Bases: direct.showbase.Job.Job

Job to check container sizes and find potential leaks; sub-job of ContainerLeakDetector

class ContainerLeakDetector(name, firstCheckDelay=None)[source]

Bases: direct.showbase.Job.Job

Low-priority Python object-graph walker that looks for leaking containers. To reduce memory usage, this does a random walk of the Python objects to discover containers rather than keep a set of all visited objects; it may visit the same object many times but eventually it will discover every object. Checks container sizes at ever-increasing intervals.

class Indirection(evalStr=None, dictKey=<class 'direct.showbase.ContainerLeakDetector.NoDictKey'>)[source]

Bases: object

Represents the indirection that brings you from a container to an element of the container. Stored as a string to be used as part of an eval, or as a key to be looked up in a dict. Each dictionary dereference is individually eval’d since the dict key might have been garbage-collected TODO: store string components that are duplicates of strings in the actual system so that Python will keep one copy and reduce memory usage

Bases: object

class ObjectRef(indirection, objId, other=None)[source]

Bases: object

stores a reference to a container in a way that does not prevent garbage collection of the container if possible stored as a series of ‘indirections’ (obj.foo -> ‘.foo’, dict[key] -> ‘[key]’, etc.)
