Metadata

  • Branch: chore/ci-pipeline-design-parallel-nox-sessions
  • Commit Message: chore(ci): implement parallel nox sessions to reduce pipeline execution time
  • Milestone: v3.2.0
  • Parent Epic: #1678

Background and Context

The noxfile.py defines several independent sessions (e.g., lint, typecheck, unit_tests) that are currently executed sequentially. Running these sessions in parallel will significantly reduce the overall pipeline execution time by taking advantage of available CI runner resources.

Sequential execution means that even when sessions have no dependency on each other, they must wait for the previous session to complete before starting. This wastes available concurrency and inflates total CI wall-clock time unnecessarily.

Expected Behavior

Independent nox sessions should be configured to run in parallel within the CI pipeline, reducing total pipeline execution time by utilizing available runner concurrency.

Acceptance Criteria

  • Independent nox sessions (e.g., lint, typecheck, unit_tests) are identified and grouped for parallel execution in the CI configuration.
  • The CI pipeline configuration is updated to run independent sessions concurrently.
  • Total CI pipeline wall-clock time is measurably reduced compared to sequential execution.
  • No session that depends on the output of another session is run in parallel with its dependency.
  • All nox sessions continue to pass after the parallelization change.

Supporting Information

  • Related issues: #1873 (Parallelize default nox sessions), #1888 (Parallelize nox sessions)
  • The noxfile.py in the project root defines all available sessions and their dependencies.

Subtasks

  • Audit noxfile.py to identify all sessions and their inter-dependencies
  • Determine which sessions are safe to run in parallel (no shared state or output dependencies)
  • Update the CI pipeline configuration (e.g., Forgejo Actions YAML) to run independent sessions concurrently
  • Validate that dependent sessions are still sequenced correctly
  • Run the full pipeline and confirm wall-clock time improvement
  • Verify coverage >= 97% via nox -s coverage_report
  • Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

  • All subtasks above are completed and checked off.
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
  • The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
  • All nox stages pass.
  • Coverage >= 97%.
