Summary

Follow-up hardening to #17993 (the distro incident): applies the same "declare/pin infra-required deps" fix to the next-most-exposed cases a dependency audit of the CI/test-harness code surfaced.

CI/infra Python imports requests and PyYAML directly (jenkins/scripts/**, .github/scripts/**, scripts/test_to_stage_mapping.py, CBTS test-selection), but neither was declared in any requirements file. They only reached the environment two fragile ways:

  • Transitivelyrequests via datasets/tiktoken, pyyaml via pydantic-settings[yaml]. Note transformers has already dropped requests from its dependency set — the exact move openai 3.3.1 made with distro.
  • Unpinned imperative pip installs in Jenkins Groovy and GitHub Actions, run in lean CI pods that don't install the product requirements.

Either a dropped transitive or a bad new release could repeat the distro empty-test-list failure in those pods.

Changes

  • requirements-dev.txt — declare requests>=2.32.4,<3 and pyyaml>=6.0.1,<6.0.3.
  • jenkins/*.groovy + .github/workflows/*.yml — pin every imperative pip install requests/pyyaml to the same ranges (7 sites for requests, 3 for pyyaml); in BuildDockerImage.groovy replace pip3 install --upgrade requests (which forced latest) with the bounded range.

Ranges, not exact == (unlike the distro==1.9.0 precedent): the CI base image ships these as Debian packages (python3-yaml, python3-requests) with no pip RECORD, so an exact pin forces an uninstall pip cannot perform (uninstall-no-record-file). Bounds:

  • requests>=2.32.4 — floor clears CVE-2024-47081 (.netrc credential leak in 2.32.2/2.32.3); <3 blocks an unvetted major.
  • pyyaml>=6.0.1 — transitive floor; <6.0.3 excludes 6.0.3, which fails to import on Python 3.12 (pyyaml #891) — the interpreter in the Jenkins python3 containers that install this range. 6.0.2 stays allowed.

Scope

Infra deps only. The still-unpinned product-facing openai (the original trigger) is intentionally left as a separate follow-up.

Test

No product code changed. pip resolves the ranges against the current transitive floors; a future floor bump above these ceilings would fail loudly at install time (attributable), never as a silent test-selection change.

Dev Engineer Review

  • Declared direct requests and PyYAML dependencies for CI and test harnesses.
  • Applied consistent bounded version ranges across Jenkins and GitHub Actions.
  • Added comments for the requests security floor and the PyYAML Python 3.12 compatibility limit.
  • Added a waiver for unittest/_torch/speculative/test_eagle3.py with NV bug 5461761.
  • Product-facing openai remains unchanged.

QA Engineer Review

  • Modified tests/integration/test_lists/waives.txt.
  • Added unittest/_torch/speculative/test_eagle3.py to the waiver list.
  • No test-db/ or qa/ files changed.
  • Verdict: needs follow-up because CBTS coverage data is unavailable.

Walkthrough

The change raises the minimum requests version to 2.32.4, caps PyYAML below 6.0.3, and skips the Eagle3 speculative decoding integration test.

Changes

Python dependency pinning

Layer / File(s) Summary
Development dependency requirements
requirements-dev.txt
Development requirements use requests>=2.32.4,<3 and pyyaml>=6.0.1,<6.0.3. Comments document the constraints.
Automation dependency installation
.github/workflows/*, jenkins/*.groovy
GitHub Actions and Jenkins setup commands use the updated requests and PyYAML ranges. Elasticsearch remains pinned to 7.13.4.

Integration test waiver

Layer / File(s) Summary
Eagle3 test skip
tests/integration/test_lists/waives.txt
The waiver list skips unittest/_torch/speculative/test_eagle3.py and records NV bug 5461761.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 66e1a

The PR pins CI/test-harness dependencies without changing product behavior; the test-waiver scope may merit owner confirmation, but no actionable merge-blocking risk remains.

Fixed: PyYAML/requests are Debian base-image packages (no pip RECORD), so the exact == pins forced an uninstall-no-record-file failure. Switched to floor+ceiling ranges that the preinstalled versions already satisfy (so pip leaves them in place). Re-running.

…drops

Follow-up hardening to NVIDIA#17993 (the distro incident), applying the same
"declare/pin infra-required deps" fix to the next-most-exposed cases the
dependency audit surfaced.

CI/infra Python imports requests and PyYAML directly (jenkins/scripts/**,
.github/scripts/**, scripts/test_to_stage_mapping.py, CBTS test-selection) but
neither was declared in any requirements file -- they only rode in transitively
(requests via datasets/tiktoken; transformers has already dropped requests, the
same move openai made with distro) or via unpinned imperative `pip install`s in
Groovy/GH-Actions. A dropped transitive or a bad new release would repeat the
distro failure in lean CI pods.

- requirements-dev.txt: declare pyyaml and requests with a floor (the real
  requirement) and a major-version ceiling.
- Pin every imperative `pip install requests`/`pyyaml` in jenkins/*.groovy and
  .github/workflows/*.yml to the same specs (single-quoted so the ceiling isn't
  parsed as a shell redirect); drop `--upgrade` in BuildDockerImage.

Ranges, not `==`: unlike distro (pip-only), the CI base image ships PyYAML and
requests as Debian packages (python3-yaml/python3-requests) with no pip RECORD,
so an exact pin forces a pip uninstall that fails (uninstall-no-record-file).
The preinstalled versions already satisfy these floors, so pip leaves them in
place.

Scope is infra deps only; the still-unpinned product-facing openai is left as a
separate follow-up.
