Worker will now try one of the following paths, relative to the flamenco-worker
executable, in order to find FFmpeg. If they cannot be found, `$PATH` is
searched for FFmpeg.
- `tools/ffmpeg-$GOOS-$GOARCH`
- `tools/ffmpeg-$GOOS`
- `tools/ffmpeg`
On Windows these paths will have a `.exe` suffix appended. `$GOOS` is the
operating system, like "linux", "darwin", "windows", etc. `$GOARCH` is the
architecture, like "amd64", "386", etc.
By accident I made the worker load `flamenco-worker.yaml` from the "local
files" directory (~/.local/share/flamenco on Linux) instead of the current
directory. This was incorrect, as that file is meant to contain
configuration that's shared between workers.
Change the location where the Worker writes its local files so that it
follows the XDG specification (instead of writing to the current working
directory).
- Linux: `$HOME/.local/share/flamenco`
- Windows: `C:\Users\UserName\AppData\Local\Flamenco`
- macOS: `$HOME/Library/Application Support/Flamenco`
NOTE: The old files will not be loaded any more. This means that if
nothing is done and the new worker is run as-is, it will reregister as a
brand new worker. Move `flamenco-worker-credentials.yaml` and
`flamenco-worker.sqlite` to the new location to avoid this.
Build with `make stresser`. Run with:
./stresser -worker UUID -secret ABCXYZ
The worker ID and secret can be obtained from
`flamenco-worker-credentials.yaml`. If left empty, the stresser will
register as a new worker, and log the credentials to be used on the next
invocation.
Add a `-withBlender` CLI argument for a unit test, to aid in debugging
T99438.
Run the test with `go test ./internal/worker/find_blender/ -args -withBlender`
to actually fail when the file association with `.blend` files cannot be
found.
Note that this doesn't rely on Blender being runnable, but it does rely
on _something_ being associated with .blend files.
`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.
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.
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.
Allow overriding the worker name by setting the `FLAMENCO_WORKER_NAME`
environment variable. This makes it easy to do from Docker configs, and,
more importantly, from the scripts I use to run multiple workers on the
same machine while developing Flamenco.
Introduce `ParameterMissingError` and `ParameterInvalidError` structs, to
be returned from command executors. These replace free-form `fmt.Errorf()`
style errors.
Fix sqlite issues in the "upstream buffer" test. The test used
`:memory:` to have an in-memory DB to separate from other tests. The
"flush at shutdown" code runs in a different goroutine, though, and
creates a new DB connection. The SQLite separation was too strong,
making that function not find any tables. This is now solved by having
an in-memory database that's shared between all connections made from
the same unit test.
Within the shutdown procedure, signing off is now the last thing the
worker does. This makes things more consistent from the Manager's point
of view (like receiving last-second log entries while the Worker is still
online).
This fixes a bug where 'Worker undefined changed status' was logged in
the web interface, as that was (back then incorrectly) `workerupdate.name`.
Now that code is correct.
