If this script is imported into the LLDB command interpreter, a "crashlog" command will be added to the interpreter for use at the LLDB command line. After a crash log has been parsed and symbolicated, a target will have been created that has all of the shared libraries loaded at the load addresses found in the crash log file. This allows you to explore the program as if it were stopped at the locations described in the crash log and functions can be disassembled and lookups can be performed using the addresses found in the crash log.''' option_parser = CreateSymbolicateCrashLogOptions ('crashlog', description, True) try: (options, args) = option_parser.parse_args(command_args) except: return if options.debug: print 'command_args = %s' % command_args print 'options', options print 'args', args if options.debug_delay > 0: print "Waiting %u seconds for debugger to attach..." % options.debug_delay time.sleep(options.debug_delay) error = lldb.SBError() if args: if options.interactive: interactive_crashlogs(options, args) else: for crash_log_file in args: crash_log = CrashLog(crash_log_file) SymbolicateCrashLog (crash_log, options) if __name__ == '__main__': # Create a new debugger instance lldb.debugger = lldb.SBDebugger.Create() SymbolicateCrashLogs (sys.argv[1:]) elif getattr(lldb, 'debugger', None): lldb.debugger.HandleCommand('command script add -f lldb.macosx.crashlog.Symbolicate crashlog') lldb.debugger.HandleCommand('command script add -f lldb.macosx.crashlog.save_crashlog save_crashlog') print '"crashlog" and "save_crashlog" command installed, use the "--help" option for detailed help'
