The main problem with your approach is the "debugger" you created is already the listener for all process events. The process requires a listener when it is launched or attached to, and since none was provided when you launched, it used the debugger.
We have an example checked in that does what you want: svn cat http://llvm.org/svn/llvm-project/lldb/trunk/examples/python/process_events.py Just take this script and modify it to your liking, or you can just use the debuggers built in listener instead of creating your own: listener = debugger.GetListener() if listener.WaitForEvent(10, event): On Mar 14, 2014, at 4:46 AM, Hikaru Gosun <[email protected]> wrote: > Hi, > > I have a small script to debug a program in OSX that looks more or less like > this: > > debugger = lldb.SBDebugger.Create() > target = debugger.CreateTargetWithFileAndArch(exe, > lldb.LLDB_ARCH_DEFAULT_64BIT) > launch_info = lldb.SBLaunchInfo(args) > launch_info.SetLaunchFlags(lldb.eLaunchFlagNone) > error = lldb.SBError() > process = target.Launch(launch_info, error) > if not error.Success(): > print args, str(error) > return > > listener = lldb.SBListener("event_listener") > process.GetBroadcaster().AddListener(listener, > lldb.SBProcess.eBroadcastBitStateChanged) > done = 0 > while not done: > event = lldb.SBEvent() > if listener.WaitForEvent(10, event): > state = lldb.SBProcess.GetStateFromEvent(event) > print state > for thread in process: > print thread, thread.GetFrameAtIndex(0) > process.Continue() > else: > done = 1 > > My intention is to debug the target with some kind of timeout, that's why I'm > trying to use the async mode and use the timeout in WaitForEvent().
