"""Smoke test for the client-side cross-node task_handle decoder.
|
||||
|
||||
Verifies:
|
||||
|
||||
1. ``Capability.IO_TASK_HANDLE`` is intact at the vendored protocol
|
||||
layer and exposed as the well-formed ``io:task_handle`` token.
|
||||
2. ``"task_handle"`` is in ``HEAVY_TYPES`` and ``is_envelope`` returns
|
||||
True for a well-formed task_handle envelope.
|
||||
3. ``decode_task_handle_envelope`` returns a ``TaskHandle`` dataclass
|
||||
with every field round-tripped verbatim (including a non-empty
|
||||
``parent_chain``).
|
||||
4. ``str(handle)`` surfaces the native_id (so UI previews / log lines
|
||||
stay human-meaningful) without leaking the lineage chain.
|
||||
5. ``encode_task_handle(decode_task_handle_envelope(env)) == env`` —
|
||||
the round-trip is lossless so a downstream provider node can re-
|
||||
emit the handle unchanged.
|
||||
6. The top-level ``decode_envelope`` dispatcher routes task_handle
|
||||
envelopes to the new decoder (so proxy_node's generic
|
||||
``_deserialize_output`` picks it up without provider-specific
|
||||
plumbing).
|
||||
7. Malformed task_handle envelopes (missing fields, wrong types,
|
||||
comma-union ``kind``, non-list ``parent_chain``, bad parent_chain
|
||||
entries, wrong encoding) raise ``RnpProtocolError`` with
|
||||
``code=INTERNAL`` — no opaque fallthrough.
|
||||
8. End-to-end against the server's ``make_task_handle_envelope``
|
||||
helper (imported from the comfy-rnp-server worktree) — the
|
||||
envelope the server packs is exactly what the client decoder
|
||||
unpacks, and ``encode_task_handle`` of the decoded result
|
||||
re-produces the same wire shape.
|
||||
9. ``CLIENT_CAPABILITIES`` advertises ``io:task_handle`` so server-
|
||||
side capability-gated descriptors negotiate cleanly.
|
||||
|
||||
Run with the ComfyUI venv (needs torch / comfy_api on PYTHONPATH):
