fix(gms): honor configured timeout during initial weights admission

[glamr-agent]

Source issue: DYN-4439.

Summary

Honor an operator-configured gms_ro_connect_timeout_ms during the initial
vLLM weights admission.

GMSWorker.init_device() already resolved this value for later failover
remapping, but omitted it when creating the initial weights client. As a result,
an explicitly configured deadline did not apply to initial admission and that
operation could wait indefinitely behind GMS lock contention.

This change adds the missing argument to
get_or_create_gms_client_memory_manager(). It does not introduce a default
timeout, change GMS lock admission, add a standby-pause deadline, alter
documentation, or claim to resolve an unproven deadlock. Deployments that do
not configure gms_ro_connect_timeout_ms retain the existing unbounded
behavior.

Validation

• pytest lib/gpu_memory_service/tests/ -q --confcutdir=lib/gpu_memory_service/tests
  — 79 passed, 12 skipped in the available CPU environment
• git diff --check
• Full repository CI required before merge

The single added unit test verifies that GMSWorker.init_device() forwards the
configured timeout without requiring a GPU or NVML.

factory: validation incomplete — the unit suites and lint passed, but the container image build and the three-worker cluster check could not run in this environment. Details below.

Automated evidence record — validation incomplete

Validation status: incomplete

Evidence summary: [3/4 validated · 1 runs in CI]

AI review assessment: sound. This is an automated review and is advisory only; it is not a human approval and does not replace one.

Validation result: the recorded validation run was made on 4ca9a79da, where the diff applied cleanly onto main and matched the branch at 7 files, +308/-2. All four suites ran green (31, 1, 64 and 6 tests passed) and lint passed over the seven changed files without rewriting one. The test that previously blocked the run is gone, confirmed by collected 1 item with the deleted test id absent. All three added tests failed correctly with their production change removed: the pause bound hangs to its 30-second guard, the shadow default fails assert None == 200, and the init_device forward fails assert None == 4200, with nothing left passing in that file. The tree was clean after every restore.

Two checks could not run here, which is why the status is incomplete:

• the container image build could not start, because no container daemon is reachable in this environment. That image is built by the Shared Build Image workflow in this repository's CI.
• three-worker Kubernetes convergence is provable only by the external test_gms_interpod_vllm.py suite, which needs a cluster.

The current head is b2a82a8607. It differs from the validated 4ca9a79da only in comment text — git show b2a82a8607 touches no executable line — which is why the live diff is +292/-2 rather than +308/-2.

Evidence audit: complete [3/4 validated · 1 runs in CI] — the command report below comes from recorded runs.

Walkthrough

The change adds configurable timeouts for shadow standby pauses and GMS read-only connections. It applies read-only timeouts during initial weights admission, caps socket connection waits at 30 seconds, and adds validation coverage.

Changes

Shadow timeout controls

Layer / File(s)	Summary
Shadow standby pause timeout components/src/dynamo/vllm/worker_factory.py, components/src/dynamo/vllm/tests/test_vllm_worker_factory.py	Shadow pauses use a 900-second default or an environment override. 0 keeps the wait unbounded. Negative and non-finite values raise RuntimeError. Positive timeout expiry occurs before election or readiness publication.
GMS read-only timeout wiring lib/gpu_memory_service/integrations/vllm/utils.py, lib/gpu_memory_service/integrations/vllm/worker.py, lib/gpu_memory_service/README.md, lib/gpu_memory_service/tests/test_vllm_worker.py	Non-primary engines receive a 900,000 ms default when no value exists. Explicit values, including None, remain unchanged. GMSWorker.init_device passes the resolved timeout to initial weights admission.
Socket connection timeout ceiling lib/gpu_memory_service/client/session.py, lib/gpu_memory_service/tests/test_runtime_flows.py	Socket connection waits use a 30-second ceiling. Tests verify that a missing socket fails within the connection timeout instead of the longer lock-admission timeout.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 511b0

The timeout documentation can mislead operators of non-primary engines. Correct the default scope before merging.

Move the unconditional imports to module scope.

.ai/python-guidelines.md requires imports to remain at the top of the file and explicitly flags imports inside function bodies. The existing HAS_GMS module-level skip runs before these imports, so moving them below that guard preserves collection-skip behavior.

Previously reported defects still present:

• Original discussion: Still present: DYN_GMS_SHADOW_PAUSE_TIMEOUT_SECONDS=NaN parses as a float and falls into the unbounded wait path because timeout_s > 0 is false, restoring the indefinite standby pause this PR is meant to prevent.
• Original discussion: Still present: test_third_shadow_client_times_out_behind_queued_writer stores delayed writer failures in queued_writer["error"] but never checks or propagates them after joining the thread.
• Original discussion: The new queued-writer test still catches and records any writer exception without asserting it after joining, so an unexpected delayed writer failure can leave the test passing.
• Original discussion: The queued-writer test still catches Exception and never checks queued_writer["error"] after joining. A delayed writer failure can therefore leave the test passing without proving the intended lock transition.
• Original discussion: The queued-writer thread still catches and stores any exception without asserting or propagating it after joining, so a delayed writer failure can leave the test passing.
• Original discussion: The timeout parser still accepts NaN and Infinity. NaN takes the non-positive branch and waits indefinitely; Infinity creates an effectively unbounded wait, restoring the startup hang this change is intended to prevent.
• Original discussion: Verified: DYN_GMS_SHADOW_PAUSE_TIMEOUT_SECONDS=NaN parses successfully, fails the timeout_s > 0 check, and takes the unbounded pause() path, restoring the indefinite standby wait this change is intended to prevent.
• Original discussion: Verified: the queued writer thread still stores arbitrary exceptions in queued_writer["error"], but the test never checks that value after joining. A delayed writer failure can therefore leave the test passing.
• Original discussion: DYN_GMS_SHADOW_PAUSE_TIMEOUT_SECONDS=NaN is accepted by float() and takes the non-positive, unbounded pause branch, so a malformed setting can reintroduce the indefinite standby hang.
• Original discussion: DYN_GMS_SHADOW_PAUSE_TIMEOUT_SECONDS=NaN still reaches the unbounded pause branch because float() accepts NaN and timeout_s > 0 is false.

factory: CI result for b2a82a8607f5563664ae21a9a72d3b440a34fb01: every pre-merge check completed, none failed, and none are still pending. Full CI on the NVIDIA runners was required but not scheduled for this head — it needs a maintainer to vet this pull request and post the copy-pr-bot approval for this commit. Authorization was not requested yet, because the automated review raised a still-open point in components/src/dynamo/vllm/worker_factory.py: a non-finite DYN_GMS_SHADOW_PAUSE_TIMEOUT_SECONDS such as NaN parses through float() but fails timeout_s > 0, so it takes the unbounded wait. That warrants a commit first.

[glamr-agent]

factory: Round 1 — addressed all six open findings in e01eb6c.

Production changes

• Non-finite shadow pause bound (components/src/dynamo/vllm/worker_factory.py). float() accepts "nan", which compares false against 0 and fell through to the unbounded pause(1) branch, and wait_for(inf) never fires. Either one restored the indefinite standby wait this change exists to remove. Both are now refused with a RuntimeError naming the variable and the accepted values.
• Connect wait kept apart from the lock-admission deadline (lib/gpu_memory_service/client/session.py). Forwarding a shadow's gms_ro_connect_timeout_ms also stretched the wait for the GMS socket itself, so a missing or refused socket took up to 15 minutes to fail instead of the 30 s availability ceiling the comment there already described. The connect wait is now min(timeout_ms, _CONNECT_TIMEOUT_MS), while the handshake still gets the caller's value unchanged. This matches v1/client/session.py, which already takes a separate connect_timeout.

Test changes

• Removed test_third_shadow_client_times_out_behind_queued_writer. Its socket assertion repeated test_waiting_writer_blocks_new_readers_until_last_reader_disconnects (same server state, same RO request, same finite timeout, same expected error). The one thing it added — that configure_gms_lock_mode supplies the deadline — needs no server and is now three unit tests in test_vllm_worker.py. Removing it also removes the blind except Exception handler whose queued_writer["error"] was never read.
• Removed the sentence in the init_device_calls docstring referring to the SGLang memory-saver tests.
• Added test_a_long_lock_deadline_does_not_stretch_the_connect_wait and three non-finite cases (nan, inf, -inf).

Replace the real sleep in the test helper.

Use an unset asyncio.Event().wait() to model a pause that never completes. The test timeout already bounds the test. As per path instructions: “real sleeps in pre-merge unit tests must be flagged.”

@glamr-agent Full review complete for #14877 at 29c24396c04740db8326da52f3b037d7e5e95b70.

I found no actionable defects.

I used the existing integration-scope information and verified the current call sites. The shadow admission default is applied only from the vLLM shadow-mode startup paths. Explicit numeric values and explicit null values remain unchanged.

The initial weights connection now receives the resolved admission timeout. The socket-connect ceiling remains independent from the GMS handshake and lock-admission deadline.

The standby-pause path rejects negative and non-finite overrides. It keeps zero as the unbounded-wait override. A pause expiry raises before election or readiness publication.

This was a static review. I did not run repository code or tests.

Learning: In the vLLM GMS integration, `lib/gpu_memory_service/integrations/vllm/utils.py:configure_gms_lock_mode()` applies the non-primary `gms_ro_connect_timeout_ms` default only when invoked by failover-shadow startup. Its production callers in `components/src/dynamo/vllm/main.py` and `components/src/dynamo/vllm/headless.py` invoke it only inside `if config.gms_shadow_mode:`. Engines outside shadow mode do not receive this default and retain an indefinite wait when no explicit timeout is configured.

nursery: Pushed 29c24396c04740db8326da52f3b037d7e5e95b70 to repair the deterministic vLLM ARM CPU-test failure in the preceding head's job 104962578466. The existing init_device_calls fixture now replaces get_socket_path with a temporary-path implementation: the real lookup reached NVML on a gpu_0 runner and failed before the timeout-forwarding assertion. No production behavior or assertions changed; no new tests were added.

Validation for this head: pinned Black, isort, Flake8, Ruff, and codespell passed locally (pre-commit was unavailable, so its Python linters were invoked directly). No local tests, builds, or benchmarks ran. Remote lightweight CI finished with 13 successful checks, 8 skipped, and no pending or failed checks. Full CI has not run for this head; the authorization request is unanswered. The repair remains unverified by the full runtime suite.

All 16 existing review threads remain resolved and GitHub reports no conflict. Requested CodeRabbit and Devin re-review once for this head; CodeRabbit completed with no actionable defects, and Devin's response is pending. The vLLM code-owner team is already requested. Requesting dynamo-gms-codeowners through the PR requested-reviewers endpoint returned HTTP 404; the follow-up read confirms that team was not added. A maintainer needs to arrange GMS review. GitHub still reports REVIEW_REQUIRED; the existing human approval was submitted on the preceding head.

Also investigated the preceding head's Triton CPU job: 117 tests passed, but collection failed because the installed image lacked get_prometheus_typed, validate_legacy_guided_decoding_constraints, and dynamo.experimental. The first two APIs exist in the checkout, and build logs show source wheels installed under the matching SHA tag; the precise image/package mismatch remains unresolved. The three available completed main runs used older/different job names and do not establish a comparable baseline. Recheck this failure in full CI and have CI/image owners investigate if it persists; do not treat it as a proven flake or a pass.

Next: authorize full CI for this exact head, inspect its results (especially the repaired vLLM CPU test and Triton collection), and complete the outstanding reviews. No base merge or redundant CI request was made. The previously documented production writer/root-cause and three-worker convergence follow-up remains open. This PR is not merge-ready.

[galletas1712]

Re-reviewed current head after the arm64 failure. The follow-up correctly stubs get_socket_path so this unit test no longer queries NVML on gpu_0 runners; production code is unchanged. Auto-merge remains appropriate after fresh full CI and code-owner approval.

No files changed, commits created, or pushes made; no local tests, builds, or benchmarks ran.

Full CI is now authorized and running for this exact head in PR workflow 35150001438. The latest snapshot has 17 successful checks, 29 skipped, and 11 in progress, with no failures. This is pending validation, not a passing result. The changed-files job enables core, vllm, and frontend; runtime image builds and Operator are still running. No duplicate CI or bot-review request was posted.

Retried the missing dynamo-gms-codeowners review request through the PR requested-reviewers endpoint: HTTP 404. The follow-up read confirms only dynamo-backend-vllm-codeowners is requested. A maintainer must arrange GMS review. The existing human approval predates this head, GitHub reports REVIEW_REQUIRED, and the previously requested Devin review has no new response.

Next: follow this head's full CI to completion, particularly the vLLM CPU timeout-forwarding test and Triton collection issues recorded in the preceding handoff; inspect any failures before further edits. Complete the outstanding code-owner reviews. The documented production writer/root-cause and three-worker convergence follow-up remains open. This PR is not merge-ready.

Galletas1712 started the rerun after the first attempt timed out in planner arm64 compliance and the frontend build. Both jobs passed on attempt 2, as did the frontend amd64/arm64 checks, frontend compliance audit, and backend-status-check. The previously recorded rerun-permission blocker is cleared. No timeout or validation policy changed. Both vLLM architecture logs explicitly record the timeout-forwarding regression test passing on this head.

All 16 review threads are resolved and the exact head has human approval. No additional review request was needed; the vLLM team was already requested. This run inspected the complete diff and monitored CI without changing source files, creating commits, pushing, running local tests/builds/benchmarks, or posting duplicate CI/bot-review requests.

The final GitHub audit reports the PR was merged by galletas1712 on September 16, 2026 at 23:01:04 UTC, as commit 4df3f3af83dd1e6ffd36d7c0a152b4efdd85f30f. I did not perform the merge. No remaining PR repair or CI blocker was found.
