Base branch: modernize/pep621-ruff (#279). That pull request stacks on
#278. Review both first. The diff here is incremental.

Action needed before this merges. The Renovate GitHub App must be
installed on this repository. Config alone does nothing. Install it at
https://github.com/apps/renovate and grant access to
jaysonsantos/python-binary-memcached. The alternative is a self-hosted
Renovate run in a GitHub Actions workflow. That needs a token with pull
request write access.

What changed

.github/workflows/tests-and-lint.yml is rewritten. It uses
actions/checkout@v7 and actions/setup-python@v7 at every call site. It adds
a concurrency group, a top-level permissions: contents: read block,
timeout-minutes on both jobs, and cache: pip on both setup-python steps.
The matrix reads ["3.10", "3.11", "3.12", "3.13", "3.14"] with
fail-fast: false. The tests job writes coverage.xml and uploads it as an
artifact.

.ci-before-script.sh, .ci-runs-tests.sh, and .travis.yml are deleted. The
workflow holds their steps inline. The Travis badge in docs/intro.rst now
points at the GitHub Actions badge.

renovate.json is new. It groups patch, minor, and digest updates into one
pull request named all non-major updates. Each major update gets its own
pull request and waits for approval on the dependency dashboard.

Why

Four action call sites held three different major versions, and no update bot
config existed, so nothing bumped them. The STEP indirection came from
Travis, which needed an environment variable to branch a build matrix. GitHub
Actions has two native jobs already, and the indirection cost real things:
pip install -e . ran twice, env printed the whole environment to a public
log, and the memcached install had no -y flag. .travis.yml called two
scripts that do not exist in this repository.

Verification

The workflow itself runs on this pull request. That is the real check.

Local checks:

nix develop --command bash -c 'pytest -q'

Result: 261 passed.

nix develop --command bash -c 'ruff check .'
nix develop --command bash -c 'ruff format --check .'

Result: All checks passed! and 23 files already formatted.

The workflow YAML, renovate.json, and .pre-commit-config.yaml all parse.
Each action tag was checked against its upstream release list:
actions/checkout is at v7.0.1, actions/setup-python at v7.0.0, and
actions/upload-artifact at v7.0.1.

Risks

A reviewer must check four points.

  1. Renovate needs the GitHub App. See the note at the top. Without it,
    renovate.json does nothing.
  2. actions/upload-artifact is pinned at v4, as the issue text
    specifies. The current release is v7.0.1. v4 still works. Renovate will
    propose the major bump on the dependency dashboard once it runs.
  3. Two renovate.json settings need your preference. timezone is
    Europe/Berlin. schedule runs once per week, before 6am on Monday.
    Change either one if it is wrong.
  4. Python 3.13 and 3.14 are new matrix legs. This pull request runs them
    for the first time. Check that both legs pass before you merge.

The pip_requirements manager is out of enabledManagers. #270 deleted
requirements_test.txt, so nothing is left for that manager to read.

Closes #271

📝 Walkthrough

Walkthrough

The pull request removes two CI shell scripts, moves their commands into GitHub Actions, adds workflow controls and coverage upload, and expands Renovate configuration for dependency updates.

Changes

CI and dependency automation

Layer / File(s) Summary
Direct CI execution
.ci-before-script.sh, .ci-runs-tests.sh, .github/workflows/tests-and-lint.yml
The legacy CI scripts were deleted. The workflow now installs dependencies and memcached directly, then runs pytest and Ruff in their respective jobs.
CI controls and reporting
.github/workflows/tests-and-lint.yml
The workflow now defines concurrency, read-only contents permissions, job timeouts, disabled matrix fail-fast, pip caching, and conditional coverage upload.
Renovate update policy
renovate.json
Renovate now uses scheduled runs, selected managers, semantic commits, lock-file maintenance, grouped non-major updates, and approval for major updates.

Explanation

The workflow satisfies the repository-coded requirements in #271: it uses checkout/setup-python v7, read-only permissions, concurrency, job timeouts, pip caching, quoted Python 3.10–3.14 matrix entries, non-fail-fast tests, inline installation and test/lint steps, coverage XML upload, and the pinned lint dependency group. The supplied change summary also reports removal of the obsolete scripts and Travis configuration and replacement of the Travis badge. renovate.json contains the required managers, grouped non-major rules, and separately approved major rules. The reviewed repository has no Renovate workflow, but repository evidence cannot establish whether the external Renovate GitHub App is installed. Repository evidence also does not include a successful pull request run for all five Python matrix legs.

The workflow used three different major action versions across four call
sites. It routed both jobs through two shell scripts. That pattern comes
from Travis, which needed an environment variable to branch a build matrix.
GitHub Actions has two native jobs already.

Workflow changes:

- actions/checkout@v7 and actions/setup-python@v7 at every call site.
- A concurrency group that cancels an outdated run in progress.
- A top-level "permissions: contents: read" block.
- timeout-minutes on both jobs.
- "cache: pip" on both setup-python steps.
- fail-fast: false, so one failed version does not hide the other results.
  max-parallel: 4 is gone. The matrix holds five legs.
- The steps run inline. The coverage run writes coverage.xml and uploads it
  as an artifact.

.ci-before-script.sh and .ci-runs-tests.sh are deleted. Both cost more than
they gave. "pip install -e ." ran twice. The "env" call printed the whole
environment to a public log. The memcached install had no -y flag.

.travis.yml is deleted. It calls .travis-before-script.sh and
.travis-runs-tests.sh. Neither file exists in the repository. The Travis
badge in docs/intro.rst now points at the GitHub Actions badge.

renovate.json is new. Renovate groups patch, minor, and digest updates into
one pull request. Dependabot cannot group by update type. Each major update
gets its own pull request and waits for approval on the dependency
dashboard.

The pip_requirements manager is out of enabledManagers. Issue #270 deleted
requirements_test.txt.

Warning: the Renovate GitHub App must be installed on this repository.
Config alone does nothing.

Refs #271
Allow Renovate to update docs/docs_requirements.txt.

Rebased onto current main (046f849). GitHub mergeability is MERGEABLE. Tip: dad093f5d208f5458fdbcba8eb63bd1471258578.

This branch now has only the two unique commits on top of main:

  • e2012aa — inline tests-and-lint workflow (checkout/setup-python @v7, concurrency, permissions, coverage artifact); delete .ci-before-script.sh and .ci-runs-tests.sh
  • dad093f — keep pip_requirements in renovate.json enabledManagers

Conflicts resolved:

  • renovate.json (add/add): kept this PR’s full Renovate config over the chore: Configure Renovate #260 stub on main
  • .ci-before-script.sh (modify/delete): deleted to match the inlined workflow

Main already had the GHA badge, .travis.yml deletion, and the #278/#279 modernization, so those were not replayed. Test harness / conftest / IPv6 / SASL fixtures stay as on main. ruff check . and ruff format --check . pass locally.

Reviewed origin/main...HEAD (commits e2012aa, dad093f).

Confirmed issue

.github/workflows/tests-and-lint.yml:70 — lint job installs unpinned Ruff instead of the pinned lint dependency group.

      - name: Run ruff
        run: |
          python -m pip install --upgrade pip
          pip install ruff
          ruff check .
          ruff format --check .

pyproject.toml defines [dependency-groups] lint = ["ruff==0.16.5"], with a comment saying to keep it in sync with the ruff-pre-commit rev in .pre-commit-config.yaml. The deleted .ci-before-script.sh already did this correctly:

if [ "$STEP" = "lint" ]; then
    pip install --group lint
fi

The rewritten workflow drops that and does pip install ruff instead, so CI always lints with whatever the latest Ruff release is, which can diverge from the pinned version used locally and in pre-commit — exactly the kind of drift the rest of this PR is trying to eliminate elsewhere (e.g. cache: pip, pinned action versions). The tests job already got this right with pip install --group test, so line 70 just needs the same treatment:

-          pip install ruff
+          pip install --group lint

Both CodeRabbit and the Codex reviewer already flagged this inline on this PR, and it's still present in the latest pushed commit (dad093f), so it isn't yet fixed.

Fix this →

Everything else checked out

  • Action pins: actions/checkout@v7, actions/setup-python@v7 at every call site; actions/upload-artifact@v4 is intentionally pinned per the PR description (Renovate will propose the major bump once installed).
  • Workflow controls: concurrency (cancel-in-progress), top-level permissions: contents: read, timeout-minutes on both jobs, cache: pip on both setup-python steps — all present and reasonable.
  • Matrix: fail-fast: false with quoted "3.10"–"3.14" legs is correct (unquoted 3.10 would parse as float 3.1).
  • Deleted scripts: confirmed every step from .ci-before-script.sh / .ci-runs-tests.sh (pip upgrade, editable install, test group install, memcached install with -y, pytest --cov, ruff check/ruff format --check) was carried into the new inline steps — apart from the lint group regression above.
  • renovate.json: pip_requirements is already back in enabledManagers (fixed in dad093f), which is needed since docs/docs_requirements.txt still exists. nix manager is enabled and flake.nix/flake.lock exist. Grouping non-major updates together and requiring dependency-dashboard approval for majors both look reasonable; timezone/schedule are the two values the PR description explicitly asks the reviewer to confirm.
  • Docs badge: docs/intro.rst already points at the GitHub Actions badge on main, so no change needed here.
  • Renovate activation: per the PR description, renovate.json alone does nothing until the GitHub App is installed on this repo (or a self-hosted Renovate workflow is added) — that's a repo-admin action outside this diff, not a code issue.

Only the one lint-pinning fix above is outstanding; the rest of the workflow and Renovate config modernization looks solid.

Use the project lint dependency group so the workflow runs the same
Ruff version as local development instead of the latest unpinned release.

Reviewed origin/main...HEAD at 28bf3ef (base branch already includes #278/#279).

Previously flagged issue: fixed

The lint job now installs the pinned dependency group instead of the latest Ruff release:

      - name: Run ruff
        run: |
          python -m pip install --upgrade pip
          pip install --group lint
          ruff check .
          ruff format --check .

This resolves the drift concern raised by CodeRabbit, Codex, and the earlier @claude review pass — CI now lints with the version pinned in pyproject.toml's lint dependency group rather than whatever Ruff last released.

Everything else checks out

  • Action pins: actions/checkout@v7, actions/setup-python@v7 at every call site; actions/upload-artifact@v4 is intentionally pinned per the PR description.
  • Workflow controls: concurrency (cancel-in-progress), top-level permissions: contents: read, timeout-minutes on both jobs, cache: pip on both setup-python steps.
  • Matrix: fail-fast: false with quoted "3.10"–"3.14" legs — correct, since unquoted 3.10 would parse as float 3.1.
  • Deleted scripts: every step from .ci-before-script.sh / .ci-runs-tests.sh was carried into inline steps, including the -y flag on the memcached install that the old script was missing.
  • renovate.json: pip_requirements is present in enabledManagers (needed for docs/docs_requirements.txt), alongside github-actions, pep621, pre-commit, and nix. Grouping non-major updates and requiring dependency-dashboard approval for majors are reasonable choices. timezone/schedule are still the two values the PR description asks the reviewer to confirm (Europe/Berlin, before 6am Monday).
  • CI status: all three checks on the latest commit (28bf3ef) are green, including Tests and Lint across all five Python matrix legs (3.10–3.14).

Minor, out-of-scope observation (not a blocker)

pyproject.toml's lint group pins ruff==0.16.8, but .pre-commit-config.yaml pins ruff-pre-commit at v0.16.5 — the comment above the pyproject.toml pin says to keep these in sync, and they've drifted. Neither file is touched by this PR, so it's pre-existing and unrelated to this change, but worth a follow-up since this PR is specifically about pinning consistency.

Outstanding, non-code items (from the PR description, unchanged)

  1. Renovate GitHub App installation — renovate.json does nothing until the app is installed on the repo (or a self-hosted workflow replaces it). This is a repo-admin action outside this diff.
  2. Confirm timezone/schedule preferences in renovate.json are correct for this repo.

Nothing further to change in this diff — the previously identified lint-pinning issue is fixed, and CI is green.
