From 76fce2dc853fd111ae64de3fa7aa9a6461568b6c Mon Sep 17 00:00:00 2001 From: Ryth Azhur Date: Wed, 6 May 2026 15:21:16 -0400 Subject: [PATCH] =?UTF-8?q?Split=20the=20registry=20=E2=80=94=20function/c?= =?UTF-8?q?omposition=20core=20+=20backend=20extensions?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The original registry tangled function, channel, composition, and form registration in a single file with polymorphic register() dispatch. That predates the household discipline; it was the design that was supposed to ship but didn't. Re-implementing the original intent. cores/mizan-python/src/mizan_core/registry.py (new): - _functions, _compositions dicts - register() — ServerFunction-only, no polymorphic dispatch - register_as(), register_compose() - register_extension(name, extension) — hook interface - get_function/get_compose/get_all_functions/get_all_compositions - get_contexts, get_context_groups - get_registry, get_schema — aggregate extension contributions - validate_registry, clear_registry — cascade-clear extensions RegistryExtension Protocol: - schema() returns the extension's schema subdict (keyed under its name) - clear() resets extension state (called by clear_registry) mizan-django/src/mizan/channels/__init__.py: - _ChannelsExtension wraps the channel _registry, plugs into core via register_extension('channels', ...). Schema output preserves the same shape codegen consumed before (snake_case keys, type+bidirectional). mizan-django/src/mizan/forms/__init__.py: - register_form() and get_forms() helpers moved here (were in setup/registry.py) - Both use mizan_core.registry under the hood. Forms don't need a separate extension because form sub-functions register as regular ServerFunctions with meta.form set. mizan-django/src/mizan/setup/registry.py: deleted. mizan-django/src/mizan/setup/__init__.py: re-exports the registry helpers from mizan_core.registry / mizan.channels / mizan.forms — the Django adapter's curated public API surface stays stable for users. Consumers updated: ~10 files imported `from mizan.setup.registry`; all switched to direct imports from mizan_core.registry, mizan.channels, or mizan.forms as appropriate. ChannelTests in test_core.py rewritten to use mizan.channels.register directly (no more polymorphic @register_as on ReactChannel subclasses). Verified: - mizan-core: 15/15 - mizan-django: 348 pass, 21 skip, 0 fail - mizan-ts edge-compat: 34/34 (cross-language pin holds) Co-Authored-By: Claude Opus 4.7 (1M context) --- backends/mizan-django/README.md | 2 +- .../src/mizan/channels/__init__.py | 41 ++ .../src/mizan/channels/connection.py | 2 +- .../mizan-django/src/mizan/client/executor.py | 2 +- .../mizan-django/src/mizan/client/function.py | 2 +- .../mizan-django/src/mizan/export/__init__.py | 2 +- .../mizan-django/src/mizan/forms/__init__.py | 49 ++- .../mizan-django/src/mizan/setup/__init__.py | 33 +- .../mizan-django/src/mizan/setup/discovery.py | 2 +- .../mizan-django/src/mizan/setup/registry.py | 373 ------------------ .../mizan-django/src/mizan/tests/test_auth.py | 2 +- .../src/mizan/tests/test_benchmarks.py | 4 +- .../src/mizan/tests/test_channels.py | 6 +- .../mizan-django/src/mizan/tests/test_core.py | 23 +- .../src/mizan/tests/test_pentest.py | 4 +- .../src/mizan/tests/test_security.py | 2 +- cores/mizan-python/src/mizan_core/registry.py | 230 +++++++++++ 17 files changed, 363 insertions(+), 416 deletions(-) delete mode 100644 backends/mizan-django/src/mizan/setup/registry.py create mode 100644 cores/mizan-python/src/mizan_core/registry.py diff --git a/backends/mizan-django/README.md b/backends/mizan-django/README.md index 7bce692..7738bf8 100644 --- a/backends/mizan-django/README.md +++ b/backends/mizan-django/README.md @@ -26,7 +26,7 @@ application = wrap_asgi(get_asgi_application()) ```python from mizan.client import client -from mizan.setup.registry import register +from mizan_core.registry import register from pydantic import BaseModel class Output(BaseModel): diff --git a/backends/mizan-django/src/mizan/channels/__init__.py b/backends/mizan-django/src/mizan/channels/__init__.py index 0b382ca..cb5f437 100644 --- a/backends/mizan-django/src/mizan/channels/__init__.py +++ b/backends/mizan-django/src/mizan/channels/__init__.py @@ -523,6 +523,47 @@ def __getattr__(name): raise AttributeError(f"module {__name__!r} has no attribute {name!r}") +# ============================================================================= +# Core Registry Extension +# ============================================================================= + + +class _ChannelsExtension: + """ + Plugs the channel registry into mizan_core.registry as the 'channels' + extension.
