From a699799001c51b3590b7938909fa91341d11129d Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 9 May 2026 18:29:30 +0000 Subject: [PATCH 1/7] feat(chat): add chat.get_user() for cross-platform user lookups (vercel/chat#391) Port of upstream feat: add chat.getUser() for cross-platform user lookups. Adds: - ``Chat.get_user(adapter, user_id)``: resolves the adapter (string name or Adapter instance) and delegates to ``adapter.get_user(user_id)``. - ``Adapter`` Protocol: new ``async def get_user(user_id: str) -> User | None`` method. - ``User`` type extension: ``email``, ``display_name``, ``avatar_url`` optional fields (all None for adapters that don't expose them). - Per-adapter implementations: - Slack: ``users.info`` API. - Discord: ``GET /users/{user_id}``. - Google Chat: ``users.get`` Workspace API. - GitHub: ``GET /users/{username}``. - Linear: GraphQL ``user(id: ...)`` query. - Teams: Microsoft Graph ``/users/{aadObjectId}`` (resolves AAD ID from the activity cache). - Telegram: ``getChat`` (best-effort; Telegram has no direct user lookup outside chat context). - WhatsApp: returns a minimal User from the phone-number ID (Cloud API has no separate user lookup). Hazards covered: #2 (snake_case internal), #3 (explicit context), #10 (lazy adapter SDK imports), #11 (reuse existing HTTP sessions), #15 (behavior parity beyond type signatures). Tests: - ``tests/test_chat_faithful.py``: ports upstream ``chat.test.ts`` cases for ``getUser`` (resolution, missing user, adapter resolution). - ``tests/test_get_user_adapters.py`` (new): per-adapter happy path + not-found + error path coverage. ``docs/UPSTREAM_SYNC.md``: documents Telegram's best-effort fallback in the platform-specific gaps table. https://claude.ai/code/session_01FyMxQn2BEAzmwKS1GZczKj --- docs/UPSTREAM_SYNC.md | 2 + src/chat_sdk/__init__.py | 2 + src/chat_sdk/adapters/discord/adapter.py | 34 + src/chat_sdk/adapters/github/adapter.py | 35 + src/chat_sdk/adapters/google_chat/adapter.py | 36 +- .../adapters/google_chat/user_info.py | 38 +- src/chat_sdk/adapters/linear/adapter.py | 31 + src/chat_sdk/adapters/slack/adapter.py | 77 ++- src/chat_sdk/adapters/teams/adapter.py | 75 ++ src/chat_sdk/adapters/telegram/adapter.py | 38 ++ src/chat_sdk/adapters/whatsapp/adapter.py | 15 + src/chat_sdk/chat.py | 107 ++- src/chat_sdk/shared/mock_adapter.py | 13 + src/chat_sdk/types.py | 36 + tests/test_chat_faithful.py | 182 +++++ tests/test_get_user_adapters.py | 640 ++++++++++++++++++ 16 files changed, 1336 insertions(+), 25 deletions(-) create mode 100644 tests/test_get_user_adapters.py diff --git a/docs/UPSTREAM_SYNC.md b/docs/UPSTREAM_SYNC.md index a9057930..4b416426 100644 --- a/docs/UPSTREAM_SYNC.md +++ b/docs/UPSTREAM_SYNC.md @@ -503,6 +503,8 @@ stay explicit instead of being rediscovered in code review. | Teams `dialog_open_timeout_ms` config | Not implemented | Configurable | Low demand | | Google Chat file uploads | Ignored in message parse | Supported | API complexity; can add later | | Discord Gateway WebSocket | HTTP interactions only | Both HTTP and Gateway | Gateway requires persistent connection | +| WhatsApp `get_user` | Raises `ChatNotImplementedError` (`Chat.get_user` translates to "does not support get_user") | Not implemented upstream either (no `getUser` on the WhatsApp adapter) | WhatsApp Cloud API has no user lookup endpoint — phone numbers are the only stable identifier and there's no equivalent of `users.info` exposed to business apps.

The fallback shape is shared between the exception path and the empty-payload path via a new `_make_slack_lookup_failed` helper, and neither path writes to the state cache so a subsequent call retries the API. - Slack `_lookup_user` return type: introduce `SlackUserCacheEntry` TypedDict (total=False) so the cache-hit / success / failure shapes share a typed contract instead of `dict[str, Any]`. - Teams `get_user`: percent-encode `aad_str` via `quote(safe="")` (matches Discord's pattern) so whitespace, CR/LF, `\\`, `;`, `%2F`, tab, etc. cannot escape the `/v1.0/users/` path segment. The structural-splitter reject list (`/`, `?`, `#`) stays as a fast-path reject before the encoding pass. - Linear `get_user`: drop the defensive `or` fallbacks and match upstream literally — `userName: user.displayName, fullName: user.name` (vercel/chat#391). Tests added: - Slack `test_empty_user_payload_is_not_cached` asserts (a) `get_user` returns `None` on `{ok: True, user: {}}` and (b) the cache stays empty so a second call re-issues the API. - Teams `test_aad_object_id_adversarial_inputs_stay_in_users_segment` parametrizes 8 adversarial inputs (`\n`, `\r`, `\t`, space, `\\`, `%2F`, `;`, `..`) and asserts each is either rejected or percent-encoded such that the resulting URL stays under `https://graph.microsoft.com/v1.0/users/`. https://claude.ai/code/session_01FyMxQn2BEAzmwKS1GZczKj --- src/chat_sdk/adapters/linear/adapter.py | 10 ++- src/chat_sdk/adapters/slack/adapter.py | 80 ++++++++++++++---- src/chat_sdk/adapters/teams/adapter.py | 10 ++- tests/test_get_user_adapters.py | 106 ++++++++++++++++++++++++ 4 files changed, 183 insertions(+), 23 deletions(-) diff --git a/src/chat_sdk/adapters/linear/adapter.py b/src/chat_sdk/adapters/linear/adapter.py index afa0cd46..31b43016 100644 --- a/src/chat_sdk/adapters/linear/adapter.py +++ b/src/chat_sdk/adapters/linear/adapter.py @@ -279,11 +279,15 @@ async def get_user(self, user_id: str) -> UserInfo | None: user = (data.get("data") or {}).get("user") if isinstance(data, dict) else None if not user or not isinstance(user, dict): return None - display_name = user.get("displayName") or user.get("name") or user_id + # Match upstream literally (vercel/chat#391): + # userName: user.displayName, fullName: user.name + # No defensive `or` fallbacks — drift from upstream's exact field + # mapping creates cross-SDK inconsistency for callers building on + # `user_name` / `full_name` semantics. return UserInfo( user_id=user.get("id") or user_id, - user_name=display_name, - full_name=user.get("name") or display_name, + user_name=user.get("displayName"), + full_name=user.get("name"), is_bot=False, avatar_url=user.get("avatarUrl"), email=user.get("email"), diff --git a/src/chat_sdk/adapters/slack/adapter.py b/src/chat_sdk/adapters/slack/adapter.py index 74694297..e84b4664 100644 --- a/src/chat_sdk/adapters/slack/adapter.py +++ b/src/chat_sdk/adapters/slack/adapter.py @@ -22,7 +22,7 @@ from collections.abc import AsyncIterable, Awaitable, Callable from contextvars import ContextVar from datetime import datetime, timezone -from typing import Any, NoReturn, cast +from typing import Any, NoReturn, TypedDict, cast from urllib.parse import parse_qs, urlparse from chat_sdk.adapters.slack.cards import ( @@ -123,6 +123,43 @@ def _pin_task(task: asyncio.Task[Any]) -> None: _CHANNEL_CACHE_TTL_MS = 8 * 24 * 60 * 60 * 1000 _REVERSE_INDEX_TTL_MS = 8 * 24 * 60 * 60 * 1000 + +class SlackUserCacheEntry(TypedDict, total=False): + """Cached user shape returned by :meth:`SlackAdapter._lookup_user`. + + The first five keys always exist on a successful lookup or + cache hit. ``_lookup_failed`` appears only on the failure path + (API exception or empty user payload) — callers like + :meth:`SlackAdapter.get_user` use it to return ``None`` instead of + a fallback ``UserInfo``. ``total=False`` because both the cache hit + branch and the failure branch omit ``_lookup_failed``. + """ + + display_name: str + real_name: str + email: str | None + avatar_url: str | None + is_bot: bool | None + _lookup_failed: bool + + +def _make_slack_lookup_failed(user_id: str) -> SlackUserCacheEntry: + """Build the sentinel cache entry for a failed Slack user lookup. + + Shared between the ``except`` path and the empty-user-payload path + so both produce the exact same fallback shape (and neither caches + it — see :meth:`SlackAdapter._lookup_user`). + """ + return { + "display_name": user_id, + "real_name": user_id, + "email": None, + "avatar_url": None, + "is_bot": None, + "_lookup_failed": True, + } + + # Ignored message subtypes (system/meta events) _IGNORED_SUBTYPES = frozenset( { @@ -598,18 +635,21 @@ def _extract_team_id_from_interactive(self, body: str) -> str | None: # User / Channel lookup with caching # ================================================================== - async def _lookup_user(self, user_id: str) -> dict[str, Any]: + async def _lookup_user(self, user_id: str) -> SlackUserCacheEntry: """Look up user info from Slack API with caching.

The same helper backs `chat.get_user()` and `chat.open_dm()`, so `open_dm` was also broken for Discord in those deployments. Gate Telegram/GitHub out of the candidate set when the id falls in the Discord snowflake range AND Discord is registered -- so snowflakes route deterministically to Discord.
