`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.
It doesn't update automatically yet (still needs SocketIO notifications),
and there is no check yet for whether there is actually any last-rendered
image at all, but at least there is a component that shows the image.
Shaman prevents duplicate checkout directories, and communicates the actual
location back to the client. This wasn't used by the add-on though, so
the Flamenco job definition would point to the wrong files.
When installing, Blender will just unzip directly into the addons dir,
so the ZIP has to contain the `flamenco` package directory.
This also makes things simpler, naming-wise. We can offer the addon from
the Manager web interface as `flamenco3-addon.zip`, and still have it
install into the `addons/flamenco` directory.
This makes it possible to start Flamenco Worker at Blender Studio with
a worker-local current working directory, with the executable in a shared
filesystem.
Having the web API client override the HTTP port for the API URL is fine
during development (when the web content is served through the Vite
devserver), but not in production.
`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.
Vue Router generates URLs for which there are no static files on the
filesystem (like `/jobs/{job ID}`). To make this work, the webapp's
`index.html` has to be served for such requests. The client-side JavaScript
then figures out how things fit together, and can even render a nice 404
page if necessary.
This shouldn't happen for non-webapp URLs, though. Because of this, the
entire webapp (including the "serve `index.html` if file not found logic)
is moved to a `/app/` base URL.
`make flamenco-manager` now also builds the webapp and embeds the static
files into the binary.
`make flamenco-manager_race` does NOT rebuild the static web files, to
help speed up of debug cycles. Run `make webapp-static` to rebuild the
webapp itself, if necessary, or run a separate web development server with
`yarn --cwd web/app run dev --host`.
Workers now send output produced by Blender (limited to PNG and JPEG
images, currently) to Manager. This is done by converting to JPEG first,
then sending the bytes via the Flamenco API to the Manager.
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.
Prepare the Worker for submission of last-rendered images to Manager, by
parsing `stdout` of Blender to see which files were saved.
This needs more work, as now just an error "not implemented" is logged.
The test can hang occasionally, and needs some love & attention. For now
I've done some patching to make it slightly better, but still disabled it
and added a `FIXME` note to it.
On Windows it's not allowed to erase a file while it's opened, which caused
this error to surface. The file is now properly closed before the test
file is erased.
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.
The OpenAPI library we use for request validation needs to know per mime
type how to handle the contents. The same function for
`application/octet-stream` is now used for `image/png` and `image/jpeg`
as well.
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.
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.
