Add a handler for the OpenAPI `taskOutputProduced` operation, and an
image thumbnailing goroutine.
The queue of images to process + the function to handle queued images
is managed by `last_rendered.LastRenderedProcessor`. This queue currently
simply allows 3 requests; this should be improved such that it keeps
track of the job IDs as well, as with the current approach a spammy job
can starve the updates from a more calm job.
Add a `local_storage` package that finds a suitable place to put files.
Currently it just looks at the location of the currently running
executable; it can later do other things. It can be queried for directory
to put job-specific files.
It is intended to be used by the under-development "last rendered output"
processing system, to store an image file per job. Later we should also
refactor the task log handling system to use this.
If there is a `scripts` directory next to the current executable, load
scripts from that directory as well.
It is still required to restart the Manager in order to pick up changes
to those scripts (including new/removed files), PLUS a refresh in the
add-on.
When a Worker indicates a task failed, mark it as `soft-failed` until
enough workers have tried & failed at the same task.
This is the first step in a blocklisting system, where tasks of an
often-failing worker will be requeued to be retried by others.
NOTE: currently the failure list of a task is NOT reset whenever it is
requeued! This will be implemented in a future commit, and is tracked in
`FEATURES.md`.
This introduces some more conceptual changes to Shaman. The most important
one is that there is no longer a "checkout ID", but a "checkout path".
The Shaman client can request any subpath of the checkout directory,
so that it can handle things like project- or scene-specific prefixes.
The task status change → job status change code is a direct port of the
Flamenco Server v2 code written in Python.
There is no job status change → task status changes logic yet, and the
tests are also far from complete.
