Simplify Python hosting core (#6492)
Remove linking, multicast, durable delivery, and host push machinery from the v1 hosting core. Keep those scenarios in a proposed follow-up ADR and update channel packages, samples, docs, tests, and workspace metadata around the smaller host/channel contract.

Python: feat(python): cross-channel hosting improvements (endpoint paths, Activity push, Telegram/Teams fixes) (#6307)
* Update hosting channel endpoint paths Treat channel paths as concrete endpoint paths so built-in channels can be mounted at their defaults or at the app root without sample-specific subclasses. Update docs, tests, and the Foundry Telegram Invocations sample accordingly. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add push support to ActivityProtocolChannel Implement the ChannelPush protocol so the Activity Protocol channel can receive cross-channel fan-out (ResponseTarget.all_linked) and echo_input replay as a non-originating destination: - Add push() that reconstructs a proactive Bot Framework activity (bot/user swap) from the stored conversation reference and POSTs it to /v3/conversations/{id}/activities. - Record a ChannelIdentity (service_url, conversation, bot, user, channel_id, locale) on ChannelRequest.identity so the host registers the channel under its isolation key for fan-out resolution. - Route the streaming path through deliver_response so Activity-originated turns broadcast like Telegram/Discord. - Add tests for push delivery, service_url validation, ChannelPush instance check, and inbound identity recording. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Don't delete Telegram webhook on shutdown by default The TelegramChannel deleted its webhook on shutdown in webhook mode. During a rolling redeploy the new revision registers the webhook on startup, then the old revision's shutdown deletes it, silently breaking inbound delivery until the next boot. setWebhook is overwriting/idempotent, so startup re-asserts the webhook every boot and no teardown is needed. Add a delete_webhook_on_shutdown flag (default False) so teardown is opt-in for ephemeral deployments, and leave the webhook in place otherwise. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix Activity channel streaming on non-Teams channels (405 on updateActivity) The Activity Protocol channel streamed replies the Teams way: POST a placeholder, then PUT-edit it as tokens arrive. Only Teams supports the updateActivity REST op; Web Chat, Direct Line and the Emulator return 405 Method Not Allowed on the PUT, so the user saw only the placeholder. Gate the placeholder+edit flow on edit-capable channels (msteams). Other channels now buffer the stream and POST a single final message, mirroring the non-streaming path's fan-out and response-hook semantics. Also add a defensive 405 fallback inside the Teams edit loop so an unexpected 405 can never strand the user on the placeholder. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-activity-protocol): don't parse Teams inline attachment content as a URI Teams message activities include a text/html attachment whose inline `content` is raw HTML (not a URL). _parse_activity fell back to `attachment["content"]` and passed it to Content.from_uri, raising ContentError ("URI must contain a scheme") and failing the whole turn, so Teams users got no response. Only treat `contentUrl` as a URI, require an absolute scheme, and skip unparseable attachments defensively instead of failing the message. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting-activity-protocol): native slash-command dispatch for Teams/Activity Add a commands= parameter to ActivityProtocolChannel that intercepts a leading /command (after stripping the bot's own @mention) and dispatches to ChannelCommand handlers, mirroring the Telegram channel. Unknown commands fall through to the agent. The channel run_hook is applied to command requests so handlers observe the same resolved isolation key as ordinary messages, and handler errors are swallowed (200, no Bot Service retry of non-idempotent commands). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): silent attributed Telegram echoes + Teams markdown rendering - hosting-telegram: send cross-channel input echoes with disable_notification (silent) and detect echo payloads so they aren't re-broadcast. - hosting-activity-protocol: render outbound + push activities as textFormat 'markdown' so Teams shows formatted replies (enables per-channel variants). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-activity-protocol): address PR #6307 review feedback Consult the host delivery pipeline even for empty streamed replies so ResponseTarget.none is honoured and non-originating fan-out is consulted instead of always emitting an originating "(no response)" message. Applies to both the progressive-edit (Teams) and buffered (Web Chat/Direct Line) streaming paths. Re-validate service_url against the allow-list in push(): the identity is read from a persisted store and push runs out-of-band, so the captured service_url must be re-checked before a bearer token is sent. Adds tests for empty-stream host consultation/suppression on both streaming paths and for push rejecting a disallowed service_url.

Python: add agent-framework-hosting-invocations channel (#5640)
* feat(hosting-invocations): add Invocations channel package New ``agent-framework-hosting-invocations`` package implementing the "Invocations" HTTP channel for the Hosting framework -- a lightweight JSON-over-HTTP shape (``POST /invocations``) for callers that want a single request/response without committing to the full OpenAI Responses envelope. Mounts onto an ``AgentFrameworkHost`` like any other channel. Surface (re-exported from ``agent_framework_hosting_invocations``): - ``InvocationsChannel`` -- concrete ``Channel`` implementation. Owns the Starlette route, parses inbound JSON into a ``ChannelRequest`` (``input`` / ``session`` / ``metadata`` / ``options``), runs the optional ``ChannelRunHook``, calls back into the ``ChannelContext`` to invoke the agent target, and returns a flat JSON envelope (or an SSE stream when ``stream=true``). - 8 unit tests covering route wiring, isolation-key passthrough, hook composition, sync vs streaming paths, and ack-only behaviour for non-originating ``DeliveryReport``s. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry. Independent of PR-3 (Responses); both depend only on PR-2 (Hosting core). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * review: address PR-4 round 2 feedback - expand `_stream` docstring to call out the HTTP-200 + `event: error` SSE contract (status committed before generator runs; hard failures surface as the first SSE frame, not an HTTP code) - split chunked text on full-line terminators via `splitlines()` so embedded `\r` / `\r\n` no longer leak into `data:` framing on the wire, breaking EventSource consumers - on `get_final_response()` failure, emit `event: error` instead of silently swallowing — finalize is what triggers history-provider persistence on the agent side, so a 5xx / disk-full / context-provider error must reach the client - add tests covering `stream_transform_hook` (rewrite, drop, async), CRLF-in-chunk framing, and the finalize-error → no-`[DONE]` contract Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(hosting-invocations): rename stale ChatMessage docstring reference to Message Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-invocations): adapt to hosted run result wrapper Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting-invocations): add response hooks Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |
