Metadata

  • Branch: chore/ci-nox-sessions-parallel
  • Commit Message: chore(ci): run all independent nox sessions in parallel across CI pipeline
  • Milestone: (none — backlog)
  • Parent Epic: #1678

Background and Context

The noxfile.py defines several independent sessions (lint, format, typecheck, security_scan, dead_code, unit_tests, integration_tests, docs, build, benchmark, coverage_report). Currently, these sessions are being run sequentially in the CI pipeline. Running them in parallel would significantly reduce the overall CI execution time, accelerating the feedback loop for developers and autonomous agents alike.

This is a broader parallelisation effort that complements the narrower #3418 (which targets only the lint and security jobs). This issue covers the full pipeline — all independent nox sessions across all CI jobs.

Subtasks

  • Audit .forgejo/workflows/ to identify all nox sessions currently run sequentially
  • Modify the CI workflow configuration to run independent nox sessions in parallel (e.g., using job matrix or background processes with wait)
  • Ensure that the CI pipeline correctly aggregates results from the parallel sessions (exit codes, logs, artefacts)
  • Verify that dependent sessions (e.g., coverage_report depends on unit_tests) remain correctly ordered
  • Monitor the CI pipeline execution time before and after to verify the improvement
  • Update the project's development guide to document the parallel execution strategy
  • Run nox (all default sessions), fix any errors
  • Verify coverage >= 97% via nox -s coverage_report

Definition of Done

  • All subtasks above are completed and checked off
  • The CI pipeline runs all independent nox sessions in parallel
  • The overall CI pipeline execution time is measurably reduced
  • Dependent sessions remain correctly sequenced (no race conditions)
  • The change is documented in the project's development guide
  • 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%

Backlog note: This issue was discovered during autonomous operation
on milestone v3.8.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.

Issue triaged by project owner:

  • State: Verified
  • Priority: High (retained from original assignment) — Running Nox sessions in parallel would significantly reduce CI execution time, which is a bottleneck for the entire development pipeline.
  • Milestone: v3.7.0
  • Story Points: 3 — M — Requires CI pipeline configuration changes and testing to ensure parallel sessions don't conflict.
  • MoSCoW: Should Have — CI performance directly impacts developer productivity and the autonomous build pipeline throughput. With 866 open bugs and 179 open PRs, faster CI is important.
