Summary

Adds tests to capture failures and performance issues when using IaaS directly and with Envoy.

Changes

  • Unit tests for ext_processor for IaaS which is used for routing decisions only
  • E2E tests (with and without Envoy)
  • Performance tests (with and without Envoy)
    • Use algorithm's ainfer to establish baseline
    • Process request with IaaS
    • Process request with Envoy + IaaS

Test Plan

  • Run new tests using a mock LLM
  • Run new tests against a real model endpoint - used google/gemma-4-12B-it
  • Tests pass locally (uv run pytest tests/)
  • Linting passes (uv run ruff check its_hub/)
  • Formatting passes (uv run ruff format --check its_hub/)

Summary by CodeRabbit

Tests

  • Added end-to-end coverage for direct IaaS requests, Envoy routing, pass-through behavior, and chat completions.
  • Added integration coverage for budget routing, header handling, response processing, lifecycle events, and error scenarios.
  • Added performance benchmarks for latency, throughput, errors, and concurrency.
  • Added reusable mock-service startup, readiness checks, and cleanup support.

Bug Fixes

  • Improved Envoy route matching for ITS service requests.

📝 Walkthrough

Walkthrough

Adds ext_proc integration tests, shared IaaS and Envoy service helpers, end-to-end routing checks, asynchronous performance benchmarks, and an orchestrator concurrency fix. The scripts support mock or external LLM endpoints, readiness checks, cleanup, and CLI execution.

Changes

IaaS and Envoy validation

Layer / File(s) Summary
Ext_proc routing and lifecycle tests
tests/test_iaas_ext_processor.py
Adds tests for budget routing, pass-through, header handling, response continuation, lifecycle handling, stream errors, and case-insensitive headers.
Service startup and request harness
tests/e2e/utils/iaas_helpers.py, its_hub/integration/iaas/envoy_config.yaml
Adds HTTP and readiness helpers, mock LLM support, production-derived Envoy configuration, route matching, IaaS configuration, service startup, and process cleanup.
End-to-end routing checks
tests/e2e/test_iaas_envoy_e2e.py
Adds direct IaaS and Envoy-routed checks with result tracking, CLI options, optional Envoy execution, service lifecycle handling, and cleanup.
Endpoint performance benchmarks
tests/e2e/test_iaas_envoy_perf.py
Adds direct algorithm, IaaS, and Envoy benchmarks with warmup, concurrency, timeout accounting, latency statistics, throughput, and baseline overhead reporting.

Orchestrator concurrency isolation

Layer / File(s) Summary
Dedicated semaphore executor
its_hub/core/orchestrator.py, tests/test_orchestrator.py
Runs blocking semaphore acquisitions in a dedicated executor and verifies that concurrent orchestrator calls complete when LM work uses the default executor.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 5731b

The change adds Envoy/IaaS test and benchmark paths while also altering orchestrator lifecycle; current issues can prevent documented test execution, leak executor resources, expose provider credentials through command-line arguments, and produce misleading benchmark results. Merge readiness is moderate: these bounded correctness, security, and runtime issues should be addressed or explicitly accepted by the owners.

40-50: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Add a sleep on the non-200 branch.

If urlopen returns a non-200 status without raising, the loop repeats with no delay. The loop then spins at full CPU until the deadline. Move the sleep out of the except block.

Capture subprocess output so startup failures are diagnosable.

Both processes send stdout and stderr to DEVNULL. If the IaaS service fails to import or bind, the raised RuntimeError reports only a timeout. The purpose of this PR is failure detection, so preserve the output.

Drop the unused llm_port parameter and start the services through their entry points.

start_iaas_stack accepts llm_port but never uses it. Both callers pass it, so the signature suggests a configuration link that does not exist. Remove the parameter, or use it and document the purpose.

The inline -c payload also reimplements what the console scripts already provide. Invoke the entry points directly instead. This keeps the command readable and matches the project convention of running commands through uv.

♻️ Proposed refactor
-def start_iaas_stack(llm_port):
+def start_iaas_stack():
     """Start ext_proc + IaaS service. Returns (processes, iaas_url, ext_proc_port).

Reuse the module-level imports.

Read the provider credential from the environment by default. Both scripts default --api_key to the literal NO_API_KEY, so a real endpoint run requires the key on the command line, where it enters shell history and process listings.

Treat the mock LLM baseline as a floor, not a reference.

start_mock_llm uses ThreadingHTTPServer with a time.sleep delay. At --concurrency 10 the Python-level mock becomes a measurement bottleneck, so the reported "Overhead vs direct" mixes gateway cost with mock server cost. Record the mock latency setting in the output, or state in the docstring that mock-mode numbers compare relative overhead only.

In `@tests/e2e/test_iaas_envoy_e2e.py`:
- Around line 197-209: Update the mock response in the handler containing
self.headers to include an its_headers_received mapping for headers whose names
start with x-its-, then update the envoy_stray_header_stripped check after
http_post to parse the response and assert that mapping is empty instead of
relying only on status 200.
- Around line 83-93: Rename the script functions test_iaas_direct and
test_envoy_routed to check_iaas_direct and check_envoy_routed so pytest does not
collect them as tests, and update both existing call sites to use the new names.
- Around line 9-20: Update all usage examples in
tests/e2e/test_iaas_envoy_e2e.py lines 9-20 and
tests/e2e/test_iaas_envoy_perf.py lines 12-27 to run the scripts as
repository-root modules via uv run python -m tests.e2e.test_iaas_envoy_e2e and
uv run python -m tests.e2e.test_iaas_envoy_perf, preserving each example’s
existing arguments.

In `@tests/e2e/test_iaas_envoy_perf.py`:
- Around line 218-221: Before calling configure_iaas in the iaas_url
configuration block, validate that llm_url is set; when it is absent, fail
immediately with a clear error message instead of configuring IaaS with a null
endpoint. Preserve the existing configuration flow when llm_url is available.
- Around line 77-95: The _single_request function currently hardcodes a
30-second ClientTimeout instead of honoring the configured timeout_s. Update the
session.post request timeout to use timeout_s, or introduce and pass a separate
explicitly configured per-request timeout, while preserving the existing error
accounting and latency collection behavior.

In `@tests/e2e/utils/iaas_helpers.py`:
- Around line 58-77: Update http_post and http_get to explicitly import
urllib.error, safely handle non-JSON response bodies by returning a status and
usable fallback body instead of propagating JSONDecodeError, and catch
urllib.error.URLError so connection failures also return the expected (status,
body) tuple for test_iaas_direct.
- Around line 199-206: Replace the deprecated exact_match field with
string_match in the generated e2e configuration and the corresponding Envoy
configuration template, preserving the X-ITS-Route header value and existing
routing behavior.

In `@tests/test_iaas_ext_processor.py`:
- Around line 231-235: Extend the assertions in the pass-through lifecycle test
around _run_process to verify the remaining response phases: assert that the
response-header and response-body entries have the expected CONTINUE status,
while preserving the existing response count and _PASS_THROUGH assertion.
- Around line 80-83: Move the ExternalProcessorService implementation from
its_hub.integration.iaas.ext_processor into an appropriate its_hub/core module,
update _make_processor and other direct imports to use the new internal
location, and expose a stable its_hub/api interface if external callers need
this service.

Do not run the routed Envoy benchmark without an LLM endpoint.

If the user supplies --envoy-url without --llm-url or --mock-llm, line 338 adds None as X-ITS-Endpoint. aiohttp rejects that header value, so every routed Envoy request fails. Skip this benchmark with a clear message, or fail argument validation before starting benchmarks.

- Around line 150-152: Update the OpenAICompatibleLanguageModel initialization
to obtain the provider credential from the appropriate environment variable,
such as OPENAI_API_KEY, instead of args.api_key; preserve the existing endpoint
and model_name values.
- Around line 172-179: Update the asyncio.TimeoutError branch around
asyncio.wait_for and the tasks created by _single_request to increment errors by
num_requests minus completed, so cancellations from the batch timeout are
counted as failed requests.

Great work. I left a few comments about deduplication and a couple quick fixes.

In `@its_hub/core/orchestrator.py`:
- Around line 28-32: Add an asynchronous shutdown hook to
_ThreadSafeAsyncSemaphore that waits for in-flight acquisitions to finish before
shutting down _executor. Invoke this hook from ITSGateway.ashutdown() as part of
the gateway lifecycle, ensuring AbstractOrchestrator-owned semaphore resources
are released without interrupting active work.

- Around line 171-178: Add PyYAML as a direct dependency in the pyproject.toml
dev extra, matching the yaml import used by generate_envoy_config in
iaas_helpers.py; do not change the helper implementation.

Resolve conflict in ITSGateway.aclose(): keep connector-pool cleanup
from this PR (drop obsolete _lm_cache lines), preserve PR #291's
orchestrator.shutdown() hook for its new ThreadPoolExecutor, and
adapt the shutdown log line to reflect pooled connectors.
