Mike Lang eba5fc498a Remove flask response size tracking 
Despite our best efforts, this was causing chunked responses to be fully
buffered into memory as a side effect.

This is really bad because responses can be VERY large.

Mike Lang 59ee5cf5c0 Only log at INFO about multiple versions of a segment 
Since these tend to happen around stream endings, etc,
we don't want them to be crazy noisy and cause us to disregard real problems.

We can use the segment coverage to see in metrics if there are overlaps.

Mike Lang 6b602592f5 Allow disabling of stacksampling with an env var 
This gives an easy way to do so across all services without adding new options.

Reasons to do so might be to avoid overheads or because your prometheus metrics grow too large.

Mike Lang 4d3aa94a71 Automatically set default encoding to utf-8 when common is imported 
To be clear, this is an awful hack.

It means that any implicit str/unicode coersion will use the utf-8 encoding,
which is basically always what you want.

However, it is possible that some badly-written libraries might be relying
on the default encoding being ascii, and will do weird things as a result.

Finally, it's especially hacky to be doing this as part of importing a library.
Normally you're meant to do this as part of a sitecustomize.py in your python system directory,
and the function is deleted before passing control to normal code (this is why we need
to reload() to get it back).

Mike Lang eb4fb5a9e1 restreamer: Add more options for fetching cuts 
Split full cut into two types - an mpegts one and an mp4 one.
Add "rough" cut which is just a concat of the segments.

Mike Lang 4d52b18b04 cutter,restreamer: Set stream=True for full cuts when appropriate 
And also default to a new ffmpeg encoding setting for high-quality mpegts
(ie. still streamable) that is encoded very quickly.

Mike Lang 9afcc7b399 full cut: Optionally use seekable file OR directly stream 
The caller can pick depending on the needs of the output format.

This reverses most of 80d829b83b,
re-introducing streaming full cuts but keeping non-streaming as an option.

Merge pull request #114 from ekimekim/mike/fixes 
Grab-bag of cutter fixes
 5 years ago
Mike Lang 80d829b83b full cut: ffmpeg requires a seekable output file 
Most formats like mp4 require ffmpeg to make changes at the start of the file
throughout writing.

Unfortunately, this prevents us from streaming the upload as we cut it.

Instead, we spool to a temporary file until ffmpeg exits,
then upload that all at once.

full cut: Fix a typo 5 years ago
Mike Lang d3e1d6b4fc Resurrect non-experimental cut, now dubbed "full" (vs "fast") cut 
In a fast cut, we edit the first and last segments then concatenate them all.
However, this leads to some tiny but perciptible artifacting around the border
of the first and second (and second-last and last) segments.

A full cut is much slower, but re-encodes the video into the desired format
and is more reliable.

We want both options to be available.

With this commit, we only add the option, we don't use it in restreamer or cutter.

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 3ccace2a73 database: Update constraints to allow null edit inputs in state DONE 
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.

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 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 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.
