After certain kinds of DB error (eg. lost conn), we need to make a new conn
to have things work again. To be safe, we just do it after every error where it might
be a problem.
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.
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).
Since we never got a new conn after failure, we would just keep erroring with
"connection already closed" errors.
This isn't applicable to the main cutter loops since a DB failure there will restart the process.
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.
nginx tries to resolve everything at startup, which doesn't work
if some of the services aren't present.
we instead generate the config file from a passed in env var, so that only
enabled services are present.
Exposes a way to read all rows, and write a single cell.
We need to read all columns of each row so we know what would be modified
so we only do updates to single cells that aren't already the correct value.
This keeps us from impacting the sheet load too much with constantly changing values,
which I think might be a thing even if the values are the same.
This allows manual uploads to work without needing to fill all the edit fields
with junk.
We also set a constraint on uploader asserting that any videos from claimed onwards have a known uploader.
Again, an exception is made for DONE to allow manual uploads.
Modified the model to place the responsibility for granular permissions on Thrimshim; rather than having a "Role Table" listing which fields can be updated by a user.
