The task log API endpoint was loading the entire log into RAM, then sending
it as response. This makes display in a browser also a bit harder.
The API endpoint now returns some JSON with info about the task log,
including its size and which URL can be used to download it.
Manifest task: T99730
This operation takes the platform & audience, and returns the variables
that are applicable for that combination. This can then be used by the
web frontend or by the Blender add-on to do variable replacement.
Include the worker's "last seen" timestamp in the worker summary, details,
and SocketIO updates.
This is different from the "updated" timestamp, which indicates the last
time the worker entry in the database was updated (which could also be
in response to a status change request from the web interface).
Change all API URL paths from `/api/…` to `/api/v3/…`. This ensures that
old Flamenco v2 clients/workers stop working when the new Manager is in
place. This also allows redirecting API calls based on the URL, also for
future upgrades.
Add an operation to get the last-rendered image from whatever job received
such output from a Worker, and add a SocketIO subscription type to receive
updates about all jobs' last-rendered images.
These are necessary for a global last-rendered image display.
`SocketIOLastRenderedUpdate` objects are meant to be broadcast to SocketIO
clients (i.e. the web interface). They are sent to the job-specific room,
just like task updates.
`os.IsNotExist()` is from before `errors.Is()` existed. The latter is the
recommended approach, as it also recognised wrapped errors.
No functional changes, except for recognising more cases of "does not
exist" errors as such.
Add an abstract queue that outputs only the last-queued item.
Items that were queued before the last one will be dropped.
This will be used for handling the last-rendered images. Any images
that are rendered while an image is already uploading should be ignored,
except the last one.
Add a function that can determine whether the given path is considered
a "root path". Considers `/`, `X:`, `X:\` and `X:/` root paths, where `X`
is any upper or lower case Latin letters.
There was no need to have the extra four letters 'nick', and some parts
of the code were already using just 'name' for the workers. This simplifies
and unifies things.
Remove the `shutdown` worker state. It was only used in Flamenco 2 to
signal to the worker that it should go offline. In other words, it didn't
use the target state in the request.
As of this change, just send `offline` as the requested state for the
worker if you want it to go offline.
Instead of always passing `status_requested` and `lazy_status_request`
in tandem, and requiring one when the other is present, they are now
always passed as a struct `WorkerStatusChangeRequest`. This struct has
both fields required.
`WorkerStatusChangeRequest` already existed, and is now altered by changing
its field `status_requested` to simply `status` -- the fact that it's
requested is already clear from the context.
This also introduces the 'lazy' status change boolean, which indicates
whether the status change should interrupt the worker's current task
(lazy=false), or only take effect after the task is finished (lazy=true).
When the web interface is showing the Workers list, it should no longer
get updates about jobs. A new subscription type `allJobs` is added, and
the `uuid` field of the subscription is no longer mandatory.
