[Bug general/4663] TaskObserver.Instruction doesn't appear to unblock on new process' first instructions


------- Additional Comments From mark at klomp dot org  2007-06-20 15:18 -------
Added a simplified test and a first workaround for this issue.

2007-06-20  Mark Wielaard  <mwielaard@redhat.com>

        * frysk-core/frysk/proc/Observation.java (toString): Include
        observable and observer.

        * frysk-core/frysk/proc/Task.java (just_started): New boolean field.

        * frysk-core/frysk/proc/TestTaskObserverInstruction.java
        (testFirstInstructionStep): New test)
        (StepAttachedObserver): New inner class.
        (testFirstInstructionSteppingEngine): Renamed method from
        testFirstInstructionStep. Remove broken marker.

2007-06-20  Mark Wielaard  <mwielaard@redhat.com>

        * frysk-core/frysk/proc/ptrace/LinuxTaskState.java
        (blockOrAttachContinue): Set just_started marker.
        (sendContinue): Reset just_started marker unless first step.
        (Running.handleTrapped): Check and reset just_started marker.

Keeping open to resolve with a real Stepping state and after consulting on other
debug step marker corner cases.
