From a62c91efa87ce9cf74dc85aec682ff5719d65068 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 30 May 2026 02:12:36 +0000 Subject: [PATCH 1/8] feat(chat): add message.subject + fetch_subject adapter hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Port the core message.subject feature from upstream eb5f94a (PR #459, "feat(chat): message.subject + adapter client access"). Tracks #98. Core type system + chat binding only: - MessageSubject dataclass (snake_case, ~10 fields) + MessageSubjectParty for the assignee/author { id, name } sub-objects, mirroring the upstream TS MessageSubject interface in packages/chat/src/types.ts. - Optional fetch_subject(raw) -> MessageSubject | None hook on BaseAdapter (default returns None). Declared on BaseAdapter (not the Adapter Protocol) to match how every other optional adapter hook is declared here, so adapters that don't implement it still satisfy Adapter for type-checking. - Message.subject async accessor backed by an identity-keyed, weakly-scoped adapter registry + cached resolution future (mirrors upstream's adapterMap WeakMap and _subjectPromise). Resolved subject is cached so a second `await message.subject` does not re-call fetch_subject; raising hooks resolve to None (mirrors upstream .catch(() => null)). - Chat registers the owning adapter at the single dispatch bind site (_dispatch_to_handlers), through which every dispatched message flows. WeakMap hashability decision: Message is a plain @dataclass (eq=True) and therefore unhashable, so weakref.WeakKeyDictionary[Message, Adapter] raises TypeError. Rather than change Message's equality contract (eq=False/frozen), we key a plain dict by id(message) (object identity, matching WeakMap semantics) and register a weakref.finalize callback per message that pops the entry on GC. weakref.ref works on a plain dataclass even though hash() does not, and the finalizer closes the id() reuse hole. Out of scope (follow-ups): GitHub + Linear adapter implementations of fetch_subject, which depend on those adapters exposing their native client (.octokit / .linear_client) — not yet present. https://claude.ai/code/session_01FyMxQn2BEAzmwKS1GZczKj --- src/chat_sdk/__init__.py | 4 + src/chat_sdk/chat.py | 8 ++ src/chat_sdk/types.py | 180 ++++++++++++++++++++++++++++++++++++ tests/test_chat_faithful.py | 41 ++++++++ tests/test_types.py | 180 ++++++++++++++++++++++++++++++++++++ 5 files changed, 413 insertions(+) diff --git a/src/chat_sdk/__init__.py b/src/chat_sdk/__init__.py index 7b121a84..7655b924 100644 --- a/src/chat_sdk/__init__.py +++ b/src/chat_sdk/__init__.py @@ -158,6 +158,8 @@ MessageContext, MessageData, MessageMetadata, + MessageSubject, + MessageSubjectParty, ModalCloseEvent, ModalResponse, ModalSubmitEvent, @@ -368,6 +370,8 @@ "MessageContext", "MessageData", "MessageMetadata", + "MessageSubject", + "MessageSubjectParty", "ModalCloseEvent", "ModalResponse", "ModalSubmitEvent", diff --git a/src/chat_sdk/chat.py b/src/chat_sdk/chat.py index a4024fb3..73bb6357 100644 --- a/src/chat_sdk/chat.py +++ b/src/chat_sdk/chat.py @@ -63,6 +63,7 @@ UserInfo, WebhookOptions, _parse_iso, + set_message_adapter, ) # --------------------------------------------------------------------------- @@ -2135,6 +2136,13 @@ async def _dispatch_to_handlers( context: MessageContext | None = None, ) -> None: """Route a message to the correct handler chain.""" + # Register the owning adapter so handlers can lazily resolve + # ``message.subject`` via the adapter's optional ``fetch_subject`` hook. + # Mirrors upstream's ``setMessageAdapter`` call at the dispatch bind + # site (packages/chat/src/chat.ts).

Pure import-style change, no behavior change; test_types.py still 40 passed. https://claude.ai/code/session_01FyMxQn2BEAzmwKS1GZczKj --- tests/test_types.py | 19 ++++++++++--------- 1 file changed, 10 insertions(+), 9 deletions(-) diff --git a/tests/test_types.py b/tests/test_types.py index cde46705..50eb0184 100644 --- a/tests/test_types.py +++ b/tests/test_types.py @@ -7,7 +7,6 @@ import weakref from datetime import datetime, timezone -import chat_sdk.types as types_module from chat_sdk.types import ( Attachment, Author, @@ -18,6 +17,8 @@ MessageSubject, MessageSubjectParty, RawMessage, + _get_message_adapter, + _message_adapter_map, set_message_adapter, ) @@ -534,10 +535,10 @@ def test_entry_removed_when_message_is_garbage_collected(self): msg = _make_message() set_message_adapter(msg, object()) key = id(msg) - assert key in types_module._message_adapter_map + assert key in _message_adapter_map del msg gc.collect() - assert key not in types_module._message_adapter_map + assert key not in _message_adapter_map def test_distinct_messages_get_distinct_adapters(self): m1 = _make_message() @@ -545,8 +546,8 @@ def test_distinct_messages_get_distinct_adapters(self): a1, a2 = object(), object() set_message_adapter(m1, a1) set_message_adapter(m2, a2) - assert types_module._get_message_adapter(m1) is a1 - assert types_module._get_message_adapter(m2) is a2 + assert _get_message_adapter(m1) is a1 + assert _get_message_adapter(m2) is a2 @staticmethod def _live_finalizer_count(message: Message) -> int: @@ -580,9 +581,9 @@ def test_re_registration_updates_adapter_value(self): msg = _make_message() adapter_a, adapter_b = object(), object() set_message_adapter(msg, adapter_a) - assert types_module._get_message_adapter(msg) is adapter_a + assert _get_message_adapter(msg) is adapter_a set_message_adapter(msg, adapter_b) - assert types_module._get_message_adapter(msg) is adapter_b + assert _get_message_adapter(msg) is adapter_b def test_re_registered_message_cleans_up_exactly_once(self): # After re-registration, GC must remove the single entry without a @@ -591,7 +592,7 @@ def test_re_registered_message_cleans_up_exactly_once(self): set_message_adapter(msg, object()) set_message_adapter(msg, object()) key = id(msg) - assert key in types_module._message_adapter_map + assert key in _message_adapter_map del msg gc.collect() - assert key not in types_module._message_adapter_map + assert key not in _message_adapter_map From 66405461a04a313d3ea83d6e93a87f1c834aeef2 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 30 May 2026 03:30:59 +0000 Subject: [PATCH 4/8] fix(types): shield cached subject future from caller cancellation (codex review) The cached `_subject_future` in `Message._subject` was awaited directly. A caller cancellation (e.g. `asyncio.wait_for(msg.subject, timeout=...)` firing) propagated into the shared future, marking it as cancelled and permanently poisoning the cache so every subsequent `await msg.subject` raised CancelledError. Wrap the cached-future await with `asyncio.shield(...)` so caller cancellation propagates to the caller while the inner task keeps running and the cache stays usable. Add a regression test that exercises the bug end-to-end (slow adapter + tight wait_for timeout + second awaiter). --- src/chat_sdk/types.py | 9 ++++++++- tests/test_types.py | 36 ++++++++++++++++++++++++++++++++++++ 2 files changed, 44 insertions(+), 1 deletion(-) diff --git a/src/chat_sdk/types.py b/src/chat_sdk/types.py index 315b7516..ae6eafc0 100644 --- a/src/chat_sdk/types.py +++ b/src/chat_sdk/types.py @@ -552,10 +552,17 @@ async def _subject(self) -> MessageSubject | None: ``ensure_future`` and stores the shared future on the instance; every later/concurrent await reuses it, so ``fetch_subject`` runs at most once.

The earlier arrivals surfaced to handlers through ``context.skipped`` had no adapter registered, so ``await context.skipped[i].subject`` always resolved to ``None`` — even when the adapter implemented ``fetch_subject``. ``_dispatch_to_handlers`` is the single registration point for adapter binding; extend it to bind every message in ``context.skipped`` before invoking the handler chain. This is the only call site that ever passes a ``MessageContext``, so no other dispatch path needs touching. Test: end-to-end burst test that drives msg1 → msg2 → msg3 through ``burst`` strategy, attaches a ``fetch_subject`` hook to the mock adapter, and asserts ``await message.subject`` *and* both ``await context.skipped[i].subject`` calls resolve to their adapter- fetched ``MessageSubject`` (not ``None``). Reverting the fix reproduces the bug exactly.

My audit-fix commit unnecessarily wrapped them. Re-applied after revert 66ef156 (which had to undo the stray pickup of unrelated messenger adapter files that bled in from a checkout to ``origin/main`` during local mypy investigation). https://claude.ai/code/session_01FyMxQn2BEAzmwKS1GZczKj --- tests/test_chat_faithful.py | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/tests/test_chat_faithful.py b/tests/test_chat_faithful.py index 8b0f760f..61e67394 100644 --- a/tests/test_chat_faithful.py +++ b/tests/test_chat_faithful.py @@ -3977,12 +3977,8 @@ def _mk(mid: str, text: str): # noqa: ANN202 msg1 = _mk("msg-burst-1", "Hey @slack-bot first") task = asyncio.create_task(chat.handle_incoming_message(adapter, "slack:C123:1234.5678", msg1)) await asyncio.sleep(0.005) - await chat.handle_incoming_message( - adapter, "slack:C123:1234.5678", _mk("msg-burst-2", "Hey @slack-bot second") - ) - await chat.handle_incoming_message( - adapter, "slack:C123:1234.5678", _mk("msg-burst-3", "Hey @slack-bot third") - ) + await chat.handle_incoming_message(adapter, "slack:C123:1234.5678", _mk("msg-burst-2", "Hey @slack-bot second")) + await chat.handle_incoming_message(adapter, "slack:C123:1234.5678", _mk("msg-burst-3", "Hey @slack-bot third")) await task # latest (msg-burst-3) dispatched as ``message``, the two earlier
