simpletrace: Improve the error message if event is not declared
Today, if we use a trace-event file which does not declare an event existing in the log file we'll get the following error: $ scripts/simpletrace.py trace-events trace-68508 Traceback (most recent call last): File "scripts/simpletrace.py", line 242, in <module> run(Formatter()) File "scripts/simpletrace.py", line 217, in run process(events, sys.argv[2], analyzer, read_header=read_header) File "scripts/simpletrace.py", line 192, in process for rec in read_trace_records(edict, log): File "scripts/simpletrace.py", line 107, in read_trace_records rec = read_record(edict, idtoname, fobj) File "scripts/simpletrace.py", line 71, in read_record return get_record(edict, idtoname, rechdr, fobj) File "scripts/simpletrace.py", line 45, in get_record event = edict[name] KeyError: 'qemu_mutex_locked' This patch improves this error by adding a hint instead of just that KeyError log: $ scripts/simpletrace.py trace-events trace-68508 'qemu_mutex_locked' event is logged but is not declared in the trace events file, try using trace-events-all instead.
