The Manager now broadcasts a worker update to SocketIO clients when a
worker gets a new task assigned. This ensures the "current task" shown in
the worker details view is up to date.
The etag prevents job submissions with old settings, when the job
compiler script has been edited. The etag is the SHA1 hash of the
`JOB_TYPE` dictionary (as defined by the JavaScript file). The hash is
computed in a way that's independent of the exact formatting in the
JavaScript file. Also the actual JS code itself is irrelevant, just the
`JOB_TYPE` dictionary is used.
Blender cannot be told to only allow absolute path for an RNA property
(of type `string`, subtype `dir_path`), so as a workaround the final
`render_output_path` is now using `bpy.path.abspath()` to make the path
absolute.
This has as advantage that the render output path can be defined by artists
as a blendfile-relative path, and that it'll be resolved when submitting
the blend file.
Remove `--factory-startup` from the default Blender arguments. This makes
it simpler to configure each Worker to use its own GPU, without having to
inject Python code into the arguments.
Users can always add this when they need, but I think it's friendlier to
have Blender behave the same when they manually run it and when used by
Flamenco Worker.
Include `RELEASE_CYCLE` in the Makefile. This is mentioned at startup of
Manager and Worker, and reflects in the software version they report.
If `RELEASE_CYCLE == "release"`, Manager and Worker report their version
as `ApplicationVersion`. If it's any other string, the Git hash will get
appended.
When a worker's tasks get requeued because it goes to sleep, the task log
will now mention the worker identification (name + UUID). This aids in
figuring out what happened to tasks.
The Task details component already linked to the Worker it was assigned
to last, and now the Worker links back to the task.
There's only one task shown in the Worker details. If the Worker is
actively working on a task, that one's shown. Otherwise it's the
last-updated task that was assigned to the worker.
This commit does not introduce functional changes, besides renaming
every mention of 'wizard' with 'setup assistant'. In order to run the
manager setup assistant use:
./flamenco-manager -setup-assistant
The change was introduced to favor more neutral and descriptive working
for this functionality. Thanks to Sybren for helping to get this done!
Remove the `{ffmpeg}` variable from the default configuration, and its use
from the job compiler scripts. Now that the Worker can find its bundled
FFmpeg, it's no longer needed to configure its location on the Manager.
* Replace "OK!" with "successfully"
Remove exclamation mark since there is no need to call for attention.
Use "successfully" as it is more descriptive in this case than OK,
which can have other meanings.
- Added initial description and illustration
- Swap "Check" button for fields with a debounced @input event
- Turn Blender's list into a radio selector
- Tweak wording when paths are not found
- Add microtip library for tooltips
- Make navigation steps clickable, according to the state
Two-way variable implementation in the job submission end-point. Where
Flamenco v2 did the variable replacement in the add-on, this has now
been moved to the Manager itself. The only thing the add-on needs to
pass is its platform, so that the right values can be recognised.
This also implements two-way replacement when tasks are handed out, such
that the `{jobs}` value gets replaced to a value suitable for the
Worker's platform as well.
Add a line to the task log whenever task changes status. This only applies
to directly-changed tasks, and not to mass-updates (like all tasks going
from 'completed' to 'queued' on a job requeue).
When a Worker changes state from `awake` to something else, it cannot
run tasks any more. This now triggers a requeue of its active task
(should be one at most, if things are sane) so that another worker can pick
it up.
SQLite often errors out on this with only `interrupted (9)` as message.
This logging should at least tell us whether it's our own "background
context" timing out, or whether something else fishy is going on.
Fix workers timing out when they're `asleep`. When sleeping, the Worker
will call the `WorkerState` operation to see if they have to wake up, but
that didn't mark the workers as "seen". As a result, a sleeping worker
would always time out.
Run some API operations in a background context. This should prevent some
of the SQLite "interrupted" errors, as those can occur when the context
closes while a query is running.
The API operations that Workers use are now mostly running in a separate
background context, at least from the moment onward when they can run
independently of the Worker connection.
Every time the web interface starts, it queries the config to see whether
it should be in first-time-wizard mode or not. This caused unnecessary
info-level logging.
In the future it would be better to load the config file just once,
instead.
For some reason, on Windows, creating a directory with zero permissions
still allows creating a file in there. Just skip that part of the test.
The Explorer's properties panel of the directory also shows "Read Only
(only applies to files)", so at least that seems consistent.
Be more selective in what's saved to the database to speed some things up.
Most importantly, this avoids saving the entire job when a task status is
updated or a task is assigned.
Add a SHA256 password hasher for worker authentication. It's not used at
the moment, but can be switched to for faster API queries. Note that
switching will cause authentication errors on already-existing workers,
which means they'll automatically re-register.
This is mostly useful for debugging & profiling purposes.
Move the Worker password hashing/comparison functions into a struct, and
use it via an interface. This will make it easier to switch to different
hashing algorithms.
Even with a low number of iterations, BCrypt is quite slow. That's good for
security, but not for Flamenco Worker authentication -- the password is
more as "nice check to avoid accidentally reusing the same ID" than
something for security.
