Description Nikolay Molchanov 2006-07-14 02:25:14 UTC

This is IZ for a new feature: "Step Into" action.
The implementation should be similar to jpda debugger.
If program is stopped, button "Step Into" should be enabled. 
If user pressed button "Step Into", the execution should be resumed, 
stopping when the beginning of the next source line is reached, if 
the next source line is not a function call. If it is, stop at the 
first instruction of the called function.

Comment 1 Nikolay Molchanov 2006-07-14 02:46:50 UTC

I upgraded priority to P1 because this feature should be implemented 
in Milestone 2B.

Comment 2 Nikolay Molchanov 2006-07-14 06:10:45 UTC

The suggested fix is to connect button "Step Into" via StepActionProvider
with method stepInto() in GdbDebuggerImpl.java, which calls method exec_step()
in GdbProxy.java, which sends "-exec-step" command to gdb. 
To implement this solution a new method is created:

File:
   cnd/gdb/src/org/netbeans/modules/cnd/debugger/gdb/GdbDebuggerImpl.java

/**
 * Resumes execution of the inferior program, stopping when the beginning of the
 * next source line is reached, if the next source line is not a function call.
 * If it is, stop at the first instruction of the called function.
 */
 public void stepInto() {
    setState(STATE_RUNNING);
    gdb.exec_step();
 }

The fix is integrated in "cnd-nb50-dev" branch.

Revision: 1.1.2.3
------------------------------------------------

For now button "Step Into" is always enabled while the debugging session 
is active. Additional changes are necessary to disable this button while
the program is running, and enable it back when the program is stopped.

Is this issue ready to be marked as fixed? If so, please change it.

Comment 4 Nikolay Molchanov 2006-09-08 15:16:06 UTC

The functionality is implemented and it seems to work just fine.
I changed the status to FIXED. If there are any problems feel free to reopen
this issue or file another one.
