Abstract

As disclosed herein a method, executed by a computer, includes receiving a request to instantiate an instance of a thread-local manager for a particular thread, instantiating the instance of the thread-local manager, and providing global visibility to the instance of the thread-local manager. The method further includes manipulating thread-local variables corresponding to the particular thread and removing all the thread-local variables when the particular thread completes a task. A computer system and computer program product corresponding to the above method are also disclosed herein.

First claim

1 - 7 . (canceled)

8 . A computer program product comprising:
one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising instructions to: receive a request to instantiate an instance of a thread-local manager for a particular thread; instantiate the instance of the thread-local manager; provide global visibility to the instance of the thread-local manager; call the thread-local manager to manipulate thread-local variables corresponding to the particular thread; and send a single command to the thread-local manager to remove all the thread-local variables when the particular thread completes a task.

9 . The computer program product of claim 8 , wherein the global visibility enables the instance of the thread-local manager to access all of the thread-local variables.

10 . The computer program product of claim 8 , wherein the program instructions comprise instructions to implement, by the instance of the thread-local manager, all capabilities corresponding to a native thread-local manager.

11 . The computer program product of claim 8 , wherein the program instructions comprise instructions to restrict instantiation of the thread-local manager to a single instance corresponding to the particular thread.

12 . The computer program product of claim 8 , wherein the instructions to manipulate the thread-local variables comprise instructions for one or more of initializing, adding, setting, getting, and removing the thread-local variables.

13 . The computer program product of claim 8 , wherein the program instructions comprise instructions to provide, by the thread-local manager, a command to remove all of the thread-local variables.

14 . The computer program product of claim 8 , wherein the task is part of a computer program that is ready to run.

15 . A computer system comprising:
one or more computer processors; one or more computer readable storage media; program instructions stored on the computer readable storage media for execution by at least one of the computer processors, the program instructions comprising instructions to: receive a request to instantiate an instance of a thread-local manager for a particular thread; instantiate the instance of the thread-local manager; provide global visibility to the instance of the thread-local manager; call the thread-local manager to manipulate thread-local variables corresponding to the particular thread; and send a single command to the thread-local manager to remove all the thread-local variables.

16 . The computer system of claim 15 , wherein the global visibility enables the instance of the thread-local manager to access all of the thread-local variables.

17 . The computer system of claim 15 , wherein the program instructions comprise instructions to implement, by the instance of the thread-local manager, all capabilities corresponding to a native thread-local manager.

18 . The computer system of claim 15 , wherein the program instructions comprise instructions to restrict instantiation of the thread-local manager to a single instance corresponding to the particular thread.

19 . The computer system of claim 15 , wherein the instructions to manipulate the thread-local variables comprise instructions for one or more of initializing, adding, setting, getting, and removing the thread-local variables.

20 . The computer system of claim 15 , wherein the program instructions comprise instructions to provide, by the thread-local manager, a command to remove all of the thread-local variables.
