Method and system for synchronizing and joining multiple calls to the same asynchronous code segment

A computing system, comprising:

• a memory configured to store:
• a first set of computer-executable instructions for an application comprising a particular code segment;
• and a second set of computer-executable instructions for a task synchronizer module that is configurable to synchronize and join multiple calls from a first thread and one or more second threads to execute the particular code segment;
• and
• a processing system configured to execute the first set and the second set of the computer-executable instructions, wherein execution of the computer-executable instructions by the processing system causes the computing system to:
• call, in response to a call from the first thread to execute the particular code segment, the particular code segment on behalf of the first thread;
• start execution of the particular code segment on behalf of the first thread;
• receive, after receiving the call from a first thread, a call from a second thread to execute the particular code segment on behalf of the first thread;
• suspend execution of the particular code segment on behalf of the second thread in response to the call from the second thread so that only the first thread is running while the second thread awaits for the execution of the particular code segment on behalf of the first thread to complete;
• store, when execution of the particular code segment completes on behalf of the first thread, a result value or exception in a task object;
• and
• read, at the second thread without executing the particular code segment, the result value or the exception that is stored in the task object on behalf of the first thread.

A computer program product for use with a computing system, the computer program product comprising a non-transitory computer readable medium having a computer readable program code embodied therein, the computer program product comprising:

• a first set of computer-executable instructions for an application comprising a particular code segment;
• and
• a second set of computer-executable instructions configurable to synchronize and join multiple calls from a first thread and one or more second threads to execute the particular code segment, wherein the second set of the computer-executable instructions are configured to:
• call the particular code segment on behalf of the first thread, in response to a call from the first thread to execute the particular code segment;
• start execution of the particular code segment on behalf of the first thread;
• receive, after receiving the call from the first thread, a call from a second thread to execute the particular code segment on behalf of the first thread;
• suspend execution of the particular code segment on behalf of the second thread in response to a call from a second thread to execute the particular code segment that is received after the call from the first thread so that only the first thread is running while the second thread awaits for the execution of the particular code segment on behalf of the first thread to complete;
• store, when execution of the particular code segment completes on behalf of the first thread, a result value or exception in a task object;
• and
• read, at the second thread without executing the particular code segment, the result value or the exception that is stored in the task object on behalf of the first thread.
