SBDebugger

class lldb.SBDebugger(*args)

SBDebugger is the primordial object that creates SBTargets and provides access to them. It also manages the overall debugging experiences.

For example (from example/disasm.py),:

import lldb
import os
import sys

def disassemble_instructions (insts):
    for i in insts:
        print i

...

# Create a new debugger instance
debugger = lldb.SBDebugger.Create()

# When we step or continue, don't return from the function until the process
# stops. We do this by setting the async mode to false.
debugger.SetAsync (False)

# Create a target from a file and arch
print('Creating a target for '%s'' % exe)

target = debugger.CreateTargetWithFileAndArch (exe, lldb.LLDB_ARCH_DEFAULT)

if target:
    # If the target is valid set a breakpoint at main
    main_bp = target.BreakpointCreateByName (fname, target.GetExecutable().GetFilename());

    print main_bp

    # Launch the process. Since we specified synchronous mode, we won't return
    # from this function until we hit the breakpoint at main
    process = target.LaunchSimple (None, None, os.getcwd())

    # Make sure the launch went ok
    if process:
        # Print some simple process info
        state = process.GetState ()
        print process
        if state == lldb.eStateStopped:
            # Get the first thread
            thread = process.GetThreadAtIndex (0)
            if thread:
                # Print some simple thread info
                print thread
                # Get the first frame
                frame = thread.GetFrameAtIndex (0)
                if frame:
                    # Print some simple frame info
                    print frame
                    function = frame.GetFunction()
                    # See if we have debug info (a function)
                    if function:
                        # We do have a function, print some info for the function
                        print function
                        # Now get all instructions for this function and print them
                        insts = function.GetInstructions(target)
                        disassemble_instructions (insts)
                    else:
                        # See if we have a symbol in the symbol table for where we stopped
                        symbol = frame.GetSymbol();
                        if symbol:
                            # We do have a symbol, print some info for the symbol
                            print symbol
                            # Now get all instructions for this symbol and print them
                            insts = symbol.GetInstructions(target)
                            disassemble_instructions (insts)

                    registerList = frame.GetRegisters()
                    print('Frame registers (size of register set = %d):' % registerList.GetSize())
                    for value in registerList:
                        #print value
                        print('%s (number of children = %d):' % (value.GetName(), value.GetNumChildren()))
                        for child in value:
                            print('Name: ', child.GetName(), ' Value: ', child.GetValue())

            print('Hit the breakpoint at main, enter to continue and wait for program to exit or 'Ctrl-D'/'quit' to terminate the program')
            next = sys.stdin.readline()
            if not next or next.rstrip('\n') == 'quit':
                print('Terminating the inferior process...')
                process.Kill()
            else:
                # Now continue to the program exit
                process.Continue()
                # When we return from the above function we will hopefully be at the
                # program exit. Print out some process info
                print process
        elif state == lldb.eStateExited:
            print('Didn't hit the breakpoint at main, program has exited...')
        else:
            print('Unexpected process state: %s, killing process...' % debugger.StateAsCString (state))
            process.Kill()

Sometimes you need to create an empty target that will get filled in later. The most common use for this is to attach to a process by name or pid where you don’t know the executable up front. The most convenient way to do this is:

target = debugger.CreateTarget('')
error = lldb.SBError()
process = target.AttachToProcessWithName(debugger.GetListener(), 'PROCESS_NAME', False, error)

or the equivalent arguments for SBTarget.AttachToProcessWithID .

RunCommandInterpreter(SBDebugger self, bool auto_handle_events, bool spawn_thread, SBCommandInterpreterRunOptions options, int & num_errors, bool & quit_requested, bool & stopped_for_crash)

Launch a command interpreter session. Commands are read from standard input or from the input handle specified for the debugger object. Output/errors are similarly redirected to standard output/error or the configured handles.

@param[in] auto_handle_events If true, automatically handle resulting events. @param[in] spawn_thread If true, start a new thread for IO handling. @param[in] options Parameter collection of type SBCommandInterpreterRunOptions. @param[in] num_errors Initial error counter. @param[in] quit_requested Initial quit request flag. @param[in] stopped_for_crash Initial crash flag.

@return A tuple with the number of errors encountered by the interpreter, a boolean indicating whether quitting the interpreter was requested and another boolean set to True in case of a crash.

Example:

# Start an interactive lldb session from a script (with a valid debugger object
# created beforehand):
n_errors, quit_requested, has_crashed = debugger.RunCommandInterpreter(True,
    False, lldb.SBCommandInterpreterRunOptions(), 0, False, False)
