This fixes the broken readiness checks introduced in the previous commit.
To support async batch generators, all of the validation of the generators needs to be async. This is problematic because a lot of the validation logic was in redux selectors, which are necessarily synchronous.
To resolve this, the readiness checks and related logic are restructured to be run async in response to redux state changes via `useEffect` (another option is to directly subscribe to redux store). These async functions then set some react state. The checks are debounced to prevent thrashing the UI.
See #7580 for more context about this issue.
Other changes:
- Fix a minor issue where empty collections were also checked against their min and max sizes, and errors were shown for all the checks. If a collection is empty, we don't need to do the min/max checks. If a collection is empty, we skip the other min/max checks and do not report those errors to the user.
- When a field is connected, do not attempt to check its value. This fixes an issue where collection fields with a connection could erroneously appear to be invalid.
- Improved error messages for batch nodes.
The "adding to" text indicates if images are going to the gallery or staging area. This info is relevant only to the canvas tab, but was displayed on Upscaling and Workflows tabs. Removed it from those tabs.
- Split up logic to determine reason why the user cannot invoke for each tab.
- Fix issue where the workflows tab would show reasons related to canvas/upscale tab. The tooltip now only shows information relevant to the current tab.
- Add calculation for batch size to the queue count prediction.
- Use a constant for the enqueue mutation's fixed cache key, instead of a string. Just some typo protection.
- Add special handling for `ImageBatchInvocation`
- Add input component for image collections, supporting multi-image upload and dnd
- Minor rework of some hooks for accessing node data
A new "session" just means to reset most settings to default values, excluding model.
There are a few things that need to be reset:
- Parameters state, except for models and things dependent on model selection (like VAE precision)
- Canvas state, except for the `modelBase`, which is dependent on the model selection
- Canvas staging area state
- LoRAs state
- HRF state
- Style presets state
We also select the canvas tab.
For new gallery sessions, we:
- Open the image viewer
- Set the right panel tab to `gallery`
And for new canvas sessions, we:
- Close the image viewer
- Set the right panel tab to `layers`
