A checkpoint-name key survives unload, so a reload of the same checkpoint never printed the per-module stats block again, even with a different quantization. Each component now carries its own reported stamp: a task switch rebuilds the pipe around the same modules and stays quiet, while a reload or a component swap brings new modules and reports them.

"""
|
|
Offline unit tests for group offload placement in modules.sd_offload_group.
|
|
|
|
Every component takes exactly one role, derived from the component itself:
|
|
|
|
- ``resident``: named by the never-offload list or the model-type exclusion, or carrying
|
|
an encode/decode entry point with no decorator for hooks to ride.
|
|
- ``ondemand``: an encode/decode entry bridge, or ``_supports_group_offloading = False``.
|
|
Group hooks are forward scoped, so these take a whole-module hook instead.
|
|
- ``main``: a component name in ``group_offload_main``, entered once per denoising step.
|
|
- ``aux``: everything else, entered once per generation.
|
|
|
|
Covers:
|
|
|
|
- ``group_offload_role`` over the component names sdnext loads, including the precedence
|
|
cases where an entry bridge or an upstream opt-out overrides a denoiser slot name
|
|
- ``apply_group_offload`` dispatching one arm per component, and the hooks landing on the
|
|
wrapper rather than the inner model for wrapper-shaped text encoders
|
|
- ``offload_ondemand`` force sweeps moving only stamped components
|
|
- a settings change re-placing a previously resident component
|
|
- ``apply_group_offload_ondemand`` return contract and idempotency
|
|
- ``get_module_names`` on both pipeline kinds
|
|
- the upstream markers the roles read
|
|
- an inventory audit deriving the role of every component of every registered pipeline,
|
|
including which components turn resident under the shipped 22 GB never-offload default
|
|
|
|
No running server required. Nothing is moved to the accelerator.
