In the future different services will write to the task log, and thus
it makes sense to move the responsibility of prepending the timestamps
to the log storage service.
The requeue-task-on-worker-signoff operation also needs to log a timestamp.
The code for this, and the recently added code for timestamping the
"task assigned to worker" message, are now unified.
A worker state change request can now be cancelled by requesting the worker
to go to its current state. In other words, a previously requested change
`A → B` can be cancelled by requesting the worker goes to state `A`.
Previously this would simply overwrite the last request, resulting in a
requested state change `A → A`. Having this non-lazy would even interrupt
the currently running task.
rFcfb17b178da2055ef12b2aa2ad8f7f778a952bc3 changed the semantics of
`SocketIOWorkerUpdate`, in the sense that any update that doesn't change
the worker status can omit `previous_status`. This commit adjusts the
unit test for this.
SocketIO clients no longer automatically subscribe to the jobs updates.
This is now done explicitly via the `allJobs` subscription type, and
unsubscribing is also possible.
A task can exist in the database but not have any log stored on disk yet.
This is now returned as `204 No Content` instead of an internal server
error.
The web interface is also adjusted to cope with this.
It returns 2048 bytes at most. It'll likely be less than that, as it will
ignore the first bytes until the very first newline (to avoid returning
cut-off lines). If the log file itself is 2048 bytes or smaller, return the
entire file.
Add a small wrapper around github.com/google/uuid. That way it's clearer
which functionality is used by Flamenco, doesn't link most of the code to
any specific UUID library, and allows a bit of customisation.
The only customisation now is that Flamenco is a bit stricter in the
formats it accepts; only the `xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx` is
accepted. This makes things a little bit stricter, with the advantage
that we don't need to do any normalisation of received UUID strings.
Implement task log broadcasting via SocketIO. The logs aren't shown in the
web interface yet, but do arrive there in a Pinia store. That store is
capped at 1000 lines to keep memory requirements low-ish.
Fix the FFmpeg unit test on Windows, by:
- Having actual input files (otherwise the input-glob-creation-function
errors out), and
- ensuring the cleanup function is always run, and
- testing for the right CLI arguments.
Rename `pkg/api/flamenco-manager.yaml` to `flamenco-openapi.yaml`, to
distinguish the OpenAPI definition file from the Flamenco Manager
configuration file of the same name (but in a different directory).
No functional changes.
