Here is a trace of TestBreakpoints under a merged ptrace/event-loop:


FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1569,tid=1569,state=running}
notifyCodeBreakpoint(134,514,608)

17-Apr-07 5:36:20 PM frysk.proc.LinuxPtraceTaskState$Running handleSignaledEvent
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1569,tid=1569,state=running}
handleSignaledEvent, signal: 5

17-Apr-07 5:36:20 PM frysk.proc.Task notifySignaled
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1569,tid=1569,state=running}
notifySignaled(int)

17-Apr-07 5:36:20 PM frysk.proc.LinuxPtraceTask sendContinue
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1569,tid=1569,state=running}
sendContinue

17-Apr-07 5:36:20 PM frysk.proc.LinuxPtraceWaitBuilder getTask
FINE: {TaskId,1569} stopped

17-Apr-07 5:36:20 PM frysk.proc.Host get
FINE: {frysk.proc.LinuxPtraceHost@17f990,state=running} get TaskId

17-Apr-07 5:36:20 PM frysk.proc.LinuxPtraceTaskState$Running handleSignaledEvent
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1569,tid=1569,state=running}
handleSignaledEvent, signal: 11

17-Apr-07 5:36:20 PM frysk.proc.Task notifySignaled
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1569,tid=1569,state=running}
notifySignaled(int)

17-Apr-07 5:36:20 PM frysk.proc.LinuxPtraceTask sendContinue
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1569,tid=1569,state=running}
sendContinue

17-Apr-07 5:36:20 PM frysk.proc.LinuxPtraceWaitBuilder getTask
FINE: {TaskId,1569} exitEvent


and here is the same trace, when the ptrace server is being used:


FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1563,tid=1563,state=running}
notifyCodeBreakpoint(134,514,608)

17-Apr-07 5:36:11 PM frysk.proc.LinuxPtraceTaskState$Running handleSignaledEvent
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1563,tid=1563,state=running}
handleSignaledEvent, signal: 5

17-Apr-07 5:36:11 PM frysk.proc.Task notifySignaled
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1563,tid=1563,state=running}
notifySignaled(int)

17-Apr-07 5:36:11 PM frysk.proc.LinuxPtraceTask sendContinue
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1563,tid=1563,state=running}
sendContinue

17-Apr-07 5:36:11 PM frysk.proc.LinuxPtraceWaitBuilder getTask
FINE: {TaskId,1563} stopped

17-Apr-07 5:36:11 PM frysk.proc.Host get
FINE: {frysk.proc.LinuxPtraceHost@17f990,state=running} get TaskId

17-Apr-07 5:36:11 PM frysk.proc.LinuxPtraceTaskState$Running handleTrappedEvent
FINE: {frysk.proc.LinuxPtraceTask@37eee0,pid=1563,tid=1563,state=running}
handleTrappedEvent


Notice how, in the first trace, after the breakpoint has been processed the next
thing back is a signal 11 - sigsegv, while, for the second case, another
breakpoint is seen.
