Summary

Adds async streaming helper methods for long-poll endpoints (PY-10) and extends OTel instrumentation to async client methods. Event-driven integrations can now consume alerts and incident updates via AsyncIterator helpers.

Acceptance Criteria

  • async def stream_alerts(self) -> AsyncIterator[Alert] added to AsyncHyperpingClient
  • async def stream_incident_updates(uuid) -> AsyncIterator[IncidentUpdate] added to AsyncHyperpingClient
  • Streaming methods use httpx2 stream context with configurable poll interval
  • OTel spans track instrumentation in async client methods
  • All 17 streaming tests pass; ruff and mypy clean on PY-10 files

Verification

Check Status
Unit tests pass ✓ 17 streaming tests + full suite
Coverage >= 85% ✓ _async_streaming_mixin.py and models/_alert_models.py both 100%
Lint (ruff check) ✓ Clean on PY-10 files
Type check (mypy) ✓ Clean on PY-10 files
OTel instrumentation ✓ Integrated into async client request path

Implementation Notes

Streaming design: stream_alerts maintains per-monitor baseline state to emit only state transitions (DOWN → UP, UP → DOWN). First poll populates baseline without yielding. stream_incident_updates pre-validates incident UUID for fast-fail UX; get_incident re-validates internally as it is also a standalone public method.

OTel spans: Async client methods now record OpenTelemetry spans for observability. Error recording integrated via record_error().

Pre-existing test failures: 19 OTel test failures in test_otel.py are PY-11 placeholders, not caused by PY-10 commits.

Followups Not in This PR

  1. src/hyperping/models/_alert_models.py:18 — AlertType.DEGRADED is defined but never emitted by stream_alerts (which only produces DOWN/UP from the down: bool field). Either remove before model stabilizes or document as forward-looking for future Hyperping API expansion.

  2. src/hyperping/_async_streaming_mixin.py:58 — baseline dict in stream_alerts is unbounded; monitors deleted from account accumulate forever. For typical bounded monitor sets negligible, but high-churn long-running listeners would see growth. TTL or periodic reconciliation can address this.

  3. tests/unit/test_streaming.py:254-291 — test_stream_alerts_respects_poll_interval and test_stream_alerts_custom_poll_interval cover identical behavior with different literal values (42.0 and 5.0). Consolidate to one.

feat(otel): wire OTel spans into HyperpingClient, AsyncHyperpingClien…
ba895b8 
…t, and MCP transports (PY-11)

Each class now calls get_tracer() in __init__ and wraps its request
chokepoint (_request for REST clients, call_tool for MCP transports) in
a start_request_span / start_rpc_span context manager. record_error is
called on HyperpingAPIError, httpx timeout, and network failure paths so
spans carry ERROR status on failures. All 23 OTel tests now pass; full
suite (603 tests) unaffected.

CI checks did not appear within 30 minutes. No CI results to report.

Verdict: CI_TIMEOUT

The monitoring period (30 min) expired before any checks were reported on this branch. This may indicate:

  • CI infrastructure is experiencing delays
  • The branch may not be properly recognized by GitHub Actions
  • Workflow configuration may need review

A human should investigate this unusual delay.

Reviewer context (not a merge request):

Bundles async streaming helpers and OTel auto-instrumentation (PY-10): httpx2 migration, _otel.py, AsyncStreamingMixin, Alert models, and wraps _request / call_tool in OTel spans.

Where to focus review: The instrumentation refactor in _async_client.py, _mcp_transport.py, _async_mcp_transport.py. The entire retry/circuit-breaker loop is now nested inside with start_request_span(...) as span: / start_rpc_span(...). Verify the circuit breaker (breaker.record_failure(), call_allowed()), retry/backoff, and the for...else: raise last_exc paths are unchanged after re-indentation; this is pure structural churn over correctness-critical code. Check record_error(span, exc) is set on every raise path and that _otel.py is a true no-op when opentelemetry-api is absent (HAS_OTEL).

Risks / verify: Heavy re-indentation makes regressions easy to miss; diff line-by-line against main. gh reports MERGEABLE: CONFLICTING (needs rebase). Overlaps heavily with #39/#44.

CI status: No checks triggered (targets main, no run recorded). Not red.

Notes: Appears to be a superset combining #39 + OTel. Reconcile with the #39 stack before merging to avoid conflicting duplicates.

…t conflicts

- pyproject: keep both the cli/typer extras (now on main) and this branch's
  otel + opentelemetry dev deps; httpx2 dependency retained.
- tests/unit/test_mcp_client.py: take main's version (adds MCP write-tool tests;
  this branch only reformatted one assert).
- uv.lock: regenerated against the merged pyproject.

Note: this branch's OTel tests (test_otel.py) require the client _tracer wiring
that lives in the PY-11 follow-up (PR #40), so they fail standalone here.

merge main into otel auto-instrumentation branch; resolve conflicts

- pyproject: keep both main's cli/typer extras and this branch's otel +
  opentelemetry dev deps; httpx2 retained.
- tests/unit/test_mcp_client.py: take main's version (MCP write-tool tests).
- uv.lock: regenerated against the merged pyproject.

This branch carries the full OTel wiring (client _tracer, PY-11), so the
test_otel.py suite passes here.

merge main into stream-alerts-empty test branch; resolve conflicts
e73d234 
Same pyproject/test/uv.lock resolution as the parent async-streaming branch.
Note: this branch shares the test/0db470 head with PR #42 (based on the
async-streaming branch) and carries the same standalone-failing test_otel.py;
the OTel client wiring lands in PR #40.

Update (conflict resolution + recommended canonical): Merged main in (same keep-both pyproject resolution, main's test_mcp_client.py, regenerated uv.lock). Now MERGEABLE / CLEAN. Local full suite: 639 passed, 1 failure that is environment-only (test_async_protocol_request_raises uses asyncio.get_event_loop(), which raises on Python 3.14; CI runs 3.11-3.13 where it passes and the same line exists on main).

This branch contains everything in #39 plus the PY-11 client _tracer wiring, so the full test_otel.py suite passes here. Recommended as the canonical OTel + async-streaming PR.

Suggested python merge order: (1) #43 MCP server, (2) #40 (httpx2 + streaming + OTel) — or #38 then #40 if you want httpx2 isolated first; do not merge both #38 and #40 paths, and #39 is subsumed by #40. (3) stacked follow-ups #45 (max_errors), #46 (async MCP).

merge async-streaming base; keep OTel layer on top
af0fb09 
Re-stack the OTel auto-instrumentation PR on the async-streaming branch so its
diff shows only the OTel layer (PY-11) on top of the streaming work (PY-10).
The streaming branch dropped its premature OTel scaffolding, so this merge
restores _otel.py, test_otel.py, the client _tracer wiring, and the
opentelemetry deps that this PR owns.
