Description

This work uses the repo’s existing auto mode/layout-driven index resolution; (public-index layout with root pylock -> requirements.cpu.txt)

  • Generate requirements for public-index baselines (341533a)
    Extended lock generation to support public-index layout (pyproject.toml -> root pylock.toml -> requirements.cpu.txt).

  • Updated baseline Dockerfiles to install Python deps from requirements.${PYLOCK_FLAVOR}.txt (101e3a1)

  • Align baseline public-index locks with paired RH/AIPCC locks (9415345)
    Added transient AIPCC-derived constraints during public-index locking to keep baseline versions aligned with sibling RH-index images.

  • Apply same requirements-based install to runtime baseline (ca2dac2)
    Regenerated runtime baseline lock artifacts (pylock.toml, requirements.cpu.txt).

How Has This Been Tested?

The GHA builds and tests are green in both streams odh n rhds in all images:

Self checklist (all need to be checked):

  • Ensure that you have run make test (gmake on macOS) before asking for review

Merge criteria:

  • The commits are squashed in a cohesive manner and have meaningful messages.
  • Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
  • The developer has manually tested the changes and verified that the changes work

Summary by CodeRabbit

  • New Features
    • Python 3.12 CPU builds now install from flavor-specific, hash-pinned requirements files.
    • Public-index projects automatically generate CPU requirements lockfiles.
    • Lockfile generation supports automatic index-mode detection and dependency alignment for baseline builds.
  • Documentation
    • Updated build, package-locking, and project documentation to describe the new requirements-file workflow.
  • Bug Fixes
    • Refreshed dependency locks and package versions for more consistent, reproducible builds.
  • Tests
    • Added coverage for public-index processing, mode detection, requirements generation, and dependency alignment.

…ines

Generate pip requirements from root pylock.toml during refresh-lock-files so jupyter/baseline and codeserver-baseline stay in sync with CI, and so a future runtimes/baseline image needs no allowlist.
…nts.txt

Switch jupyter/baseline and codeserver-baseline Dockerfiles from `uv pip sync ./pylock.toml` to hashed `requirements.${PYLOCK_FLAVOR}.txt` so the image build consumes the same pip lock as refresh-lock-files.

📝 Walkthrough

Walkthrough

The change adds automatic RH-index or public-index selection based on project layout. Public-index processing now generates requirements.cpu.txt from the root lockfile and can apply temporary baseline alignment constraints. Three Python 3.12 CPU Dockerfiles install flavor-specific hashed requirements files with uv pip install. Baseline lockfiles and requirements files are refreshed. Documentation and unit tests cover the new workflows.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to ca2da

The baseline image build changes can download unverified dependencies and may retain packages outside the declared dependency set, causing unintended image contents or runtime behavior. Lock regeneration may also produce non-repeatable output that fails repository checks, so these issues should be fixed before merging.

📋 Review Summary

This PR extends lock generation and Dockerfile build paths to support public-index layouts (pyproject.toml -> root pylock.toml -> requirements.cpu.txt), ensuring consistent package version alignment and reproducible builds across baseline notebook and runtime images. All changes look clean, well-tested, and consistent with the repository's locking workflow.

🔍 General Feedback

  • The automated additions of requirements files and corresponding documentation updates correctly reflect the new public-index layout handling.
  • The alignment logic and associated unit tests in scripts/pylocks_generator.py and tests/unit/scripts/test_pylocks_generator.py are robustly structured.

Test failures assessment, not related with the changes of this PR:

  1. RH Konflux builds, are failing because of no subscription manager registered in ODH. This builds will fixed next week when we will go to hermetic builds.
  2. check-generated-code gha failing because of AIPCC pulp/index issues
  3. Dependency Review failing because of protobuf vulnerable version that we have pined because on s390x compatibility

The GHA builds and tests are green in both streams odh n rhds in all images:

Restore exact synchronization in the runtime baseline.

uv pip install does not remove packages already present in the Python base image. The --strict option does not provide exact-environment synchronization. Restore uv pip sync ./pylock.toml or explicitly remove packages outside the generated lock to prevent an unreviewed dependency surface (CWE-1395).

We have pined the version of the protobuf because of the UPB C extension segfaults on s390x issue. but yeah, we have to figure out what we will do with that version I hope in latest versions there in no the issue

@jiridanek I could not verify protobuf==7.36.0.

PyPI returns HTTP 404 for both protobuf==7.36.0 and protobuf==6.36.0. The checked releases include 6.33.0 through 6.33.6.

The repository pin remains protobuf==6.31.1. The affected pyproject.toml files document the UPB C-extension s390x segfault from 6.33.6+.

Upstream protocolbuffers/protobuf#24103 confirms a Python s390x regression starting at 6.33.0. Upstream protocolbuffers/protobuf#25363 contains a big-endian UPB fix. The available release data does not prove that a released Python package includes that fix.

Do not update the pin based on 7.36.0 yet. After the release exists, qualify the exact package on native s390x before removing the pin.

@atheo89 The Jira lookup failed. I could not verify RHAIENG-7037 status, target version, or s390x test requirements.

The dependency assessment remains inconclusive. Keep protobuf==6.31.1 until a released package contains the UPB big-endian fix and native s390x regression tests pass. This is required before removing the mitigation for the s390x segfault.
