Abstract

Methods and systems are disclosed for controlled processing of a plurality of log statements. In an embodiment, the method includes accessing a database of unique identifiers for each of the log statements. The unique identifiers are generated based at least on a file name and a line number corresponding to each of the log statements. The method also includes determining a status corresponding to each of the unique identifiers. The status represents either an “on” or an “off” status of the log statements associated with each of the unique identifiers. The one or more of the log statements are processed based on the status of each of the log statements.

Claims

1. A method for controlled processing of a plurality of log statements, the method comprising:

accessing a database of unique identifiers for each of the plurality of log statements, the unique identifiers being generated based at least in part on a file name and a line number corresponding to each of the log statements;

determining a status corresponding to each of the unique identifiers, the status representing either an “

on”

or an “

off”

status of the log statements associated with each of the unique identifiers; and

processing one or more of the plurality of log statements based on the determined status of each of the log statements.

2. The method as in claim 1, wherein the method further comprises:

determining the file name and the line number corresponding to each of the log statement during compilation;

concatenating the file name and the line number with an identification token to generate the unique identifiers for each of the plurality of the log statements; and

storing the unique identifiers in the database.

3. The method as in claim 1, wherein the method further comprises creating a sparse bitmap array storing values representing the status of the log statement.

4. The method as in claim 3, wherein the determining comprises:

computing an offset value for each of the unique identifiers based on virtual addresses of the unique identifiers in the database; and

accessing the sparse bitmap array based on the offset value to determine the status corresponding to each of the unique identifiers.

5. A system for controlled processing of one or more log statements in a program code, the system comprising:

an exclusive logging module configured to identify and process a log statement from the one or more log statements based at least in part on a combination of plurality of unique parameters associated with the log statement, the plurality of unique parameters comprising a file name and a line number associated with the log statement.

6. The system as claimed in claim 5, wherein the system further comprises a database configured to create and maintain, at run-time, the unique parameters corresponding to each of the plurality of log statements.

7. The system as claimed in claim 5, wherein the unique parameters correspond to a log level associated with each of the log statements.

8. The system as claimed in claim 5, wherein the exclusive logging module is configured to present a user-interface to enable a user to specify the one or more of the plurality of unique parameters.

9. The system as claimed in claim 5, wherein the exclusive logging module is configured to process the log statement if the parameters associated with the log statement corresponds to an “

on”

status.

10. The system as claimed in claim 5, wherein the controlled processing is independent of processor type.

11. The system as claimed in claim 5, wherein the controlled processing is independent of type of operating system.

12. The system as claimed in claim 5, wherein the exclusive logging module corresponds to a sub-module in a C/C++ compiler.

13. An exclusive logging system, the system comprising:

a data structure configured to represent, at runtime, either an ‘

on’

or an ‘

off’

status corresponding to a log statement in a program code, the representation based at least in part on a combination of a line number and a file name associated with the log statement; and

a compiler configured to access the data structure and execute the log statement based at least in part on the status.

14. The exclusive logging system as in claim 13, wherein the exclusive logging system further comprises a database configured to create, maintain, and look-up, at run-time, the file name and the line number corresponding to the log statement.

15. The exclusive logging system as in claim 13, wherein the log statement corresponds to a macro.

16. The exclusive logging system as in claim 13, wherein the log statement corresponds to a macro for generation of log or trace reports.

17. The exclusive logging system as in claim 13, wherein the compiler is configured to present a user interface that enables a user to set the ‘

on’

or ‘

off’

state at runtime by specifying the file name and the line number corresponding to the log statement.

18. The exclusive logging system as in claim 13, wherein the program compiler is configured to present a user interface that enables a user to query the status of the log statement.

19. The exclusive logging system as in claim 13, wherein the representation is based at least in part on a combination of one or more of:

a log level, the line number, and the file name associated with the log statement.

20. The exclusive logging system as in claim 14, wherein the compiler is configured to execute a macro that concatenates the file name and the line number with identification token to generate a unique identifier.
