Avoid crash when timestamp decoding fails

[jfessard]

Timestamp sometimes comes back as None, and the parsing would fail,
crashing the script.
I've run this diff for a continuous week, without any script crashes and
no data going missing for more than a minute (I have my Grafana alerts
set up).

This addresses #3

Sorry I hadn't gotten a chance to look into your issue before. Thanks for the PR!

[jfessard]

No worries, I figured since I had it fixed locally, might as well submit a PR!
Does the docker container get updated automatically, or it has to be rebuilt? Thanks!

[abaker]

Yup, auto build here

Hmm, I have pulled image: bakerba/emu2influx:latest but I am still seeing the same crash (running on a intel NUC, so it should pick up amd64)

Traceback (most recent call last):
  File "emu2influx.py", line 127, in <module>
</Command>
    main(client=emu(args.serial_port), db=influx)
  File "emu2influx.py", line 65, in main
    timestamp = get_timestamp(instantaneous_demand)
  File "emu2influx.py", line 16, in get_timestamp
    return datetime.utcfromtimestamp(Y2K + int(obj.TimeStamp, 16)).isoformat()
TypeError: int() can't convert non-string with explicit base

that should be gone with my PR

I'm not sure if this was because I had caching enabled on the auto-build, or if something got messed up with the multi-arch latest setup, but if you do bakerba/emu2influx:amd64-latest or armhf-latest it should get you the right version

*EDIT - fixed

I was using bakerba/emu2influx:latest and it was bad. with bakerba/emu2influx:amd64-latest it's all good.

Original response:

Very strange, I am pulling latest, but I still hit the crash (withing seconds of running the docker). When I run my own python script in a tmux shell, it's good indefinitely. I checked the python file inside the docker, and it doesn't have the change.

docker-compose.yml:

  emu2influx:
    image: bakerba/emu2influx:latest
    container_name: emu2influx

Crash:

    timestamp = get_timestamp(instantaneous_demand)
  File "emu2influx.py", line 16, in get_timestamp
    return datetime.utcfromtimestamp(Y2K + int(obj.TimeStamp, 16)).isoformat()
TypeError: int() can't convert non-string with explicit base
