[CRITICAL BUG] event serialization error in store.py #330

Closed ivelin closed 3 years ago

Describe the bug After merging PR #314 , there is an exception in store.py when it tries to save a detection event.

To Reproduce Run edge with fall detection and observe log.

ivelin commented 3 years ago

@bhavikapanara looks like the numpy.float32 doesn't have a default string representation. Here is more on this. Should be a simple fix.

Please test thoroughly end to end with UI rendering falls and object detections in the timeline.

ivelin commented 3 years ago

@bhavikapanara there is a new critical serialization issue after the #332 merge. Worse yet, the new merge was pushed to production and effectively stopped all edge devices from functioning.

Now we not only have to promptly resolve the root cause, but also include a recovery script in the next merge that cleans up corrupted timeline event files and allows edge devices to resume function without user intervention. Not an ideal situation, but this is the price we pay for incomplete end to end testing.

Looking at the exception in the edge log, the format store.py serializes post #332 merge is some sort of weird proprietary stuff that cannot be deserialized by the regular json library used in the flasker web API.

Please review carefully and make sure to test end to end, including UI before submitting the next PR. Also add more tests for to REST API to be sure it can function with the event serialization format.

Here is the new exception in the web API when it tries to respond to a UI request:

@bhavikapanara here is a possible solution to the graceful recovery from corrupted event timeline files.

Starting here:

           try:
                timeline_events = yaml.safe_load(pf)
                timeline_events += events_queue
            except (
                yaml.reader.ReaderError, 
                yaml.scanner.ScannerError,
            ):
                log.exception("Detected unreadable timeline, removing %s" % file_path)
                remove_timeline(file_path)
                continue

add handler for the new exception we are seeing : yaml.composer.ComposerError: found duplicate anchor 'id001'; first occurrence

as follows

           try:
                timeline_events = yaml.safe_load(pf)
                timeline_events += events_queue
            except (
                yaml.reader.ReaderError, 
                yaml.scanner.ScannerError,
                yaml.composer.ComposerError
            ) as e:
                log.exception(f"Detected unreadable timeline, removing {file_path}", e)
                remove_timeline(file_path)
                continue

This will unfortunately wipe out all events in the file that has corrupted data, including good ones, which is not ideal, but hopefully we will not get into this same type of issues anytime soon.

@ivelin Instead of removing the timeline, can we ignore the only corrupt event data to render on UI?

That would be better. How do you suggest we do that?

ivelin commented 3 years ago

Users are starting to complain that their edge is not responsive. We need to push a fix sooner than later.

bhavikapanara commented 3 years ago

Yes...will do that as soon as possible
