US 8,510,530 B1 · Memory management for programs operating asynchronously

Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing memory for programs operating asynchronously. In one aspect, a method includes receiving, by a first process and from a second process that is asynchronous to the first process a request to perform operations; and a first callback referencing an executable portion of the second process; generating a wrapper callback referencing the first callback, the wrapper callback configured to deallocate a referenced memory location and cause execution of the referenced first callback when the wrapper callback is executed; and in response to performing operations based on the request, the operations including allocating the referenced memory location, executing the wrapper callback, including executing the first callback and deallocating the referenced memory location subsequent to executing the first callback.

Dependent claims

A computer-implemented method performed by a data processing apparatus, comprising:

receiving, by a first process and from a second process that is asynchronous to the first process:
a request to perform operations;
and
a first callback referencing an executable portion of the second process;
generating a wrapper callback referencing the first callback, the wrapper callback configured to deallocate a referenced memory location and cause execution of the referenced first callback when the wrapper callback is executed;
and
in response to performing the operations based on the request, the operations including allocating the referenced memory location, executing the wrapper callback, including executing the first callback and deallocating the referenced memory location subsequent to executing the first callback.

A system, comprising:

a data processing apparatus;
and
a memory coupled to the data processing apparatus having instructions stored thereon which, when executed by the data processing apparatus cause the data processing apparatus to perform operations comprising:
receiving, by a first process and from a second process that is asynchronous to the first process:
a request to perform operations;
and
a first callback referencing an executable portion of the second process;
generating a wrapper callback referencing the first callback, the wrapper callback configured to deallocate a referenced memory location and cause execution of the referenced first callback when the wrapper callback is executed;
and
in response to performing the operations based on the request, the requested operations including allocating the referenced memory location, executing the wrapper callback, including executing the first callback and deallocating the referenced memory location subsequent to executing the first callback.

Non-transitory computer readable media storing software comprising instructions executable by a processing device and upon such execution cause the processing device to perform operations comprising:

receiving, by a first process and from a second process that is asynchronous to the first process:
a request to perform operations;
and
a first callback referencing an executable portion of the second process;
generating a wrapper callback referencing the first callback, the wrapper callback configured to deallocate a referenced memory location and cause execution of the referenced first callback when the wrapper callback is executed;
and
in response to performing the operations based on the request, the requested operations including allocating the referenced memory location, executing the wrapper callback, including executing the first callback and deallocating the referenced memory location subsequent to executing the first callback.
