Managing code-tracing data
A method of managing code-tracing data in a target program is described. The method comprises the steps of: identifying when an exception occurs in the target program; accessing a stack trace of a call stack to identify a module in the target program that threw the exception; and activating code-tracing at a high detail level in that module.
1. A method of managing code-tracing data in a target program, the method comprises the steps of:
identifying when an exception occurs in the target program;
accessing a stack trace of a call stack to identify a module in the target program that threw the exception;
assigning a level of code tracing in that module including activating code-tracing at a high detail level in that module; and
returning the code-tracing levels to a default value after a time period expires with no exception being thrown.
2. A method according to claim 1 , wherein the method comprises the further steps of:
accessing the stack trace to identify a module in the target program that called the exception-throwing module; and
activating code-tracing at a medium detail level in that module.
3. A method according to claim 2 , wherein the method comprises the further steps of:
accessing the stack trace to identify a module in the target program that called the module that called the exception-throwing module; and
activating code-tracing at a low detail level in that module that called the module that called the exception-throwing module.
4. A method according to claim 3 , wherein the method comprises the further step of:
activating code-tracing at a minimal detail level in the rest of the target program.
5. A method according to claim 1 , wherein the method comprises the further steps of:
identifying modules called by the exception-throwing module; and
activating code-tracing at a medium detail level in those modules.
6. A method according to claim 5 , wherein the step of identifying the called modules is implemented using a call identification module that analyses the exception module.
7. A method according to claim 1 , wherein the method comprises the additional step of:
accessing a code-tracing map that indicates what code-tracing settings should be activated if an exception occurs in a specified module.
8. A method of managing code-tracing data in a target program, the method comprises the steps of:
identifying when an exception occurs in the target program;
accessing a stack trace of a call stack to identify a module in the target program that threw the exception;
assigning a level of code tracing in that module including activating code-tracing at a high detail level in that module; and
decreasing the code-tracing levels over time if no exception is thrown.
9. A method of managing code-tracing data in a target program, the method comprises the steps of:
identifying when an exception occurs in the target program;
accessing a stack trace of a call stack to identify a module in the target program that threw the exception;
assigning a level of code tracing in that module including activating code-tracing at a high detail level in that module; and
increasing the code-tracing levels over time if an exception is thrown within a preset time period of restarting the target program.
10. A method of managing code-tracing data in a target program, the method comprises the steps of:
identifying when an exception occurs in the target program;
accessing a stack trace of a call stack to identify a module in the target program that threw the exception;
activating code-tracing at a high detail level in that module; and
returning the code-tracing levels to a default value after a time period expires with no exception being thrown.
11. A method of managing code-tracing data in a target program, the method comprises the steps of:
identifying when an exception occurs in the target program;
accessing a stack trace of a call stack to identify a module in the target program that threw the exception;
activating code-tracing at a high detail level in that module; and
decreasing the code-tracing levels over time if no exception is thrown.

identifying when an exception occurs in the target program;
accessing a stack trace of a call stack to identify a module in the target program that threw the exception;
activating code-tracing at a high detail level in that module; and
