Mike Lang cca4d52b7d Don't error when encountering a temp-type segment 
These can happen if a downloader or backfiller dies suddenly.
We treat it similarly to partial but lacking any hash.

At some point in the future we should probably have something
to find any temp segments, hash them and rename them to partials.

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 5b2a1ef6b7 cutter: Implement actual cut methods 
Each method is fairly complicated, but is self-contained and can be examined independently.

cut_jobs in particular contains several extra helpers and directs control flow
via some iterators. This is unfortunately nessecary due to the requests interface.

Mike Lang ae809c696c cutter: Outline of how main cutter run loop works 
This commit only lays out the main loop, showing the high-level flow
and defining shared utilities. This is for clarity.

The actual methods that do the work will be implemented seperately.

Mike Lang 80c1a66aa0 cutter: Implement TranscodeChecker 
It runs on an interval, fetching all videos in TRANSCODING from the DB,
checking them against youtube, and then updating any that are done.

It should be noted that youtube somewhat lies about what being "done" means,
but this is a better approximation than nothing.

Mike Lang 3ce8360a1e cutter: Add database manager and connections 
One connection each for transcode checker and cutter.
We don't need more than one each since both workers only ever do one thing at once.
 6 years ago
Mike Lang fdd245a6d9 cutter: Add lightweight youtube client 
Provides basic youtube api calls, and gets passed into both transcode checker and cutter.

The official youtube client library is many orders of magnitude larger and more complicated,
and can't actually do what we want (stream an upload of unknown size).

Mike Lang dfc64481a6 Port existing cutting code from restreamer into common 
Note this moves over the 'experimental' cutter and deletes the original cutter
that concatenates entire videos before cutting.
We may eventually want to revive that method if the experimental cutter turns out
to introduce too many issues.

We move most of the code over verbatim, but adjust it such that it acts
as a generic iterator that can be used in a variety of contexts.

Some other changes made during the move include telling ffmpeg to be quieter
(don't output version info and junk, only log if something goes wrong),
and avoiding errors during cleanup.

Mike Lang 3d9ba77745 common: add allow_holes option to get_best_segments() to abort early if holes found 
This is a performance optimization, allowing us to fail out early (potentially avoiding a LOT
of work) if we know we're going to reject any result that contains holes.

We add a new exception ContainsHoles that is raised in this condition.

Mike Lang e4b6110fd7 cutter: Add initial outline 
The cutter has two jobs:
* To cut videos, taking them through states EDITED -> TRANSCODING
* To monitor TRANSCODING videos for when they're complete

We run these as separate greenlets with their own DB connections,
and if either dies we gracefully shut down the other.

Christopher Usher f43c699e05 updated thrimshim to handle all non-null edit columns 6 years ago
Mike Lang e383613954 database: Add constraints on edit inputs that they must be non-NULL if state != UNEDITED 
This should help prevent changing state to EDITED with any of these fields unset,
which would blow up the cutter.

We also fix up upload_location, which was set up as a sheet input (NOT NULL DEFAULT ''),
and add a similar constraint saying any DONE columns must have non-NULL video link.

Mike Lang 292188ad7c database: Remove retry_on_conflict helper and default to autocommit 
All our usage was of a single query anyway, so autocommit is easier to handle.
You can still opt into a longer transaction using the transaction() helper.

Mike Lang 73640ed4ab database: Add column video_id for storing upload-location-specific metadata for identifying video 
ie. for youtube, the video id.

Mike Lang dc2eb6ed74 Add some common database code 
This code manages the database connections, setting their isolation level correctly
and ensuring the idempotent schema is applied before they're used.

Applying the schema on startup means we don't need to deal with the database's state,
setting it up before running, running migrations etc. However, it does put constraints on
the changes we can safely make.

Our use of seralizable isolation means that all transactions can be treated as fully
independent - the server must behave as though they'd been run seperately in some valid order.
This will give us the least surprising results when multiple connections try to modify the same
data, though we'll need to deal with occasional transaction commit failures due to conficts.
