Abstract

A monitoring tool continuously monitors for insertion, call or deletion of objects from a session. Display of this information shows any get object, set object or remove object operations in the session and shows the entry and exit points for each such object, thus assisting the user whenever objects inserted or called remain in the session and are not removed, thus allowing the user to prevent any data buildup in the session.

Claims

1. A processor-implemented method of identifying any inserted and unremoved objects in the source code of a session under development comprising steps of:

inspecting said code for any new session access instruction that either enters, reads or removes an object,

storing the entry, exit or read point of said access instruction in a data file,

comparing the content of said data file with the content of said code to determine which of said entry, exit or read points remains in said data file but not in said code, and

displaying the entry, exit or read point of an object stored in said data file.

2. The method of claim 1, further comprising:

removing from said data file any stored entry, exit or read point of an object, which is found by said comparing, not to be present in said code when said comparison is made.

3. The method of claim 1, wherein

said displaying displays an identity of any session interaction instruction creating an entry, exit or read point in conjunction with each said entry, exit or read point remaining in said data file.

4. The method of claim 1, further comprising:

highlighting an identity of any said entry, exit or read point from said data file.

5. A process-implemented method, during a code development session, of identifying an inserted and unremoved object in source code, comprising:

identifying a change made to the source code during the code development session;

inspecting the change to identify whether the change includes an instruction that enters an object into the session, reads an object into the session, or removes an already present object from the session;

storing, as an entry, an entry point, a read point, or an exit point, corresponding to the instruction, into a data file; and

comparing entries in the data file with the source code to determine whether the instruction is present in the source code.

6. The method of claim 5, further comprising:

removing, from the source code and after the comparing, the instruction.

7. The method of claim 5, further comprising:

removing, from the data file and upon determining that the instruction is not present in the source code, the entry point, the read point, or the exit point that corresponds to the instruction.

8. The method of claim 5, further comprising:

displaying an identity of the instruction in conjunction with the entry point, the read point, or the exit point corresponding to the instruction.

9. A computer hardware system for, during a code development session, identifying an inserted and unremoved object in source code, comprising:

a processor, wherein the processor is configured to perform;

identifying a change made to the source code during the code development session;

inspecting the change to identify whether the change includes an instruction that enters an object into the session, reads an object into the session, or removes an already present object from the session;

storing, as an entry, an entry point, a read point, or an exit point, corresponding to the instruction, into a data file; and

comparing entries in the data file with the source code to determine whether the instruction is present in the source code.

10. The system of claim 9, wherein the processor is further configured to perform:

removing, from the source code and after the comparing, the instruction.

11. The system of claim 9, wherein the processor is further configured to perform:

removing, from the data file and upon determining that the instruction is not present in the source code, the entry point, the read point, or the exit point that corresponds to the instruction.

12. The system of claim 9, wherein the processor is further configured to perform:

displaying an identity of the instruction in conjunction with the entry point, the read point, or the exit point corresponding to the instruction.

13. A computer program product comprising a computer usable storage memory having stored therein computer usable program code for, during a code development session, identifying an inserted and unremoved object in source code, the computer usable program code, which when executed by a computer hardware system, causes the computer hardware system to perform:

identifying a change made to the source code during the code development session;

inspecting the change to identify whether the change includes an instruction that enters an object into the session, reads an object into the session, or removes an already present object from the session;

storing, as an entry, an entry point, a read point, or an exit point, corresponding to the instruction, into a data file; and

comparing entries in the data file with the source code to determine whether the instruction is present in the source code.

14. The computer program product of claim 13, wherein the computer usable program code further causes the computer hardware system to perform:

removing, from the source code and after the comparing, the instruction.

15. The computer program product of claim 13, wherein the computer usable program code further causes the computer hardware system to perform:

removing, from the data file and upon determining that the instruction is not present in the source code, the entry point, the read point, or the exit point that corresponds to the instruction.

16. The computer program product of claim 13, wherein the computer usable program code further causes the computer hardware system to perform:

displaying an identity of the instruction in conjunction with the entry point, the read point, or the exit point corresponding to the instruction.
