US 2018/0018206 A1 · WORKFLOW-BASED OBJECT DESTRUCTION

Abstract

Objects in a computing environment are often utilized by threads through an object lifecycle, and are destroyed at the end of the object lifecycle to reclaim the computing resources used by the object. In some cases, a thread that initiates an object destruction of an object may be unable to complete the destruction (e.g., a second thread may hold a synchronization lock over an object resource of the object). An object destruction workflow initiates the destruction of an object on behalf of a thread. If the object destruction workflow encounters a failure to complete the object destruction, a new reference to the object is inserted into an object destruction list, as the last reference to the object. A second thread discovers and releases the last reference in the object destruction list, prompting the object destruction workflow to resume the attempt to destroy the object on behalf of the second thread.

Dependent claims

A device that destroys objects within a reference-counting environment of a device, the device comprising:

a processor, and
a memory storing:
an object destruction list of references to objects to be destroyed;
and
an object destruction workflow executed by the processor on behalf of a first thread that:
responsive to releasing a last reference to an object accessed by the first thread:
attempts to destroy the object;
and
responsive to failing to complete destruction of the object, adds a new reference to the object to the object destruction list, as the last reference to the object;
and
responsive to identifying, for the object, the last reference to the object added to the object destruction list by a second thread, releases the last reference to the object.
