Mike Lang f50276bd01 backfiller: Expose recent_cutoff as CLI arg and increase it to 120s default
In testing, GDQ's stream delay went up over 1min, which caused backfillers to backfill
segments at the same time they were downloaded. We increase the window for now,
and also make it configurable.

Mike Lang 29040a166c backfiller: Allow multiple concurrent segment downloads
This will signifigantly increase throughput when downloading
large ranges of segments.

The max concurrency is exposed as a cli arg.

We also slightly modify the logged info, so it reports segments downloaded,
not just number of missing segments (which we might skip downloading for various reasons).

Christopher Usher 37bad7d5ed Also reset database connection on error in the backfiller 5 years ago
Mike Lang 7179fcacec Backfiller: ignore temp segments
To make this work, we make type a proper segment field.

We also tell get_best_segments to ignore temp segments, since they might go away
before we can actually use them.

Mike Lang f8d10dacdf Audit and fix all usage of dateutil
We wrap direct dateutil calls to handle two distinct cases:

* `common.dateutil.parse()`: We want to handle arbitrary timestamps including tz info,
then convert them to UTC.

This is used in HLS parsing, and for command line input for backfiller

* `common.dateutil.parse_utc_only()`: We want to only handle UTC timestamps,
but datetime.strptime isn't flexible enough (eg. can't handle missing fractional component).

This is used for restreamer request params.

Mike Lang 901cda4814 Enable backdoor in all services, and add telnet to containers 6 years ago
Mike Lang 9af7795f34 Add gevent.backdoor as an optional arg to all services
Backdoor allows the operator to telnet into the given port, and get a python shell
running inside the process, from which you can debug, modify state (eg. set the log level),
or whatever. This is extremely useful for debugging weird states that you encounter randomly
but can't easily reproduce, without restarting the process and needing to wait until it happens again.

Mike Lang 90ccc6d827 backfiller: Track number of successful backfills
Other stats can come later, but this one is important as it tells us if
a downloader hasn't been doing its job.

Mike Lang b4b315b6bc Expose prometheus metrics for backfiller and downloader 6 years ago
Mike Lang b0ded641c3 Add a logging handler which counts logs for prometheus stats
This isn't as good as having a full centralised logging system, but should
suffice to know if anything funny is happening.
