Ticket

CHA-2963. First of the five repos following the getstream-go pilot (CHA-4852, getstream-go#143).

Problem

The bump script computed the version from the merged PR title, committed pyproject.toml locally so the tag pointed at a correct tree, and pushed only the tag. The default branch was never updated, so pyproject.toml and the uv.lock self-entry on main both still say 4.1.0 while PyPI is at 6.1.0.

Solution

release-please keeps the bump in a reviewable Release PR, so the version files on main match the release.

  • release-please-config.json / .release-please-manifest.json, python strategy, manifest seeded at 6.1.0.
  • include-component-in-tag: false keeps the tag as vX.Y.Z instead of getstream-vX.Y.Z.
  • last-release-sha is the main commit v6.1.0 was released from. The tag itself sits on the off-branch bump commit the old workflow created, so release-please cannot reach it by walking main and would otherwise treat the whole history as unreleased.
  • A TOML extra-file keeps the uv.lock self-entry in step with pyproject.toml, which CI needs because run_tests.yml sets UV_FROZEN=1.
  • release.yml rewritten around the action, then unit and integration, then uv publish. The workflow file name and the pypi environment are unchanged, which is what PyPI Trusted Publishing binds to. Publishing chains inside the same run because a GitHub Release created with GITHUB_TOKEN starts no new workflow run.
  • pr_title.yml added, matching getstream-go: with squash merges the PR title becomes the commit subject, so a non-conventional title silently ships nothing.
  • scripts/release/bump_version.py deleted, README release section rewritten, and the empty ## [Unreleased] heading removed so the generated section lands at the top.

The first Release PR also repairs the 4.1.0 drift in pyproject.toml and uv.lock.

How to verify

Dry-run against a throwaway branch carrying one fix: commit (release-please release-pr --dry-run --trace), now deleted:

  • proposes 6.1.1 from base v6.1.0
  • pyproject.toml 4.1.0 -> 6.1.1
  • uv.lock line 898 4.1.0 -> 6.1.1, that line only
  • CHANGELOG.md section inserted above ## [4.2.0]
  • compare link v6.1.0...v6.1.1, so the tag shape is unchanged

actionlint clean on both workflows.

Expected on merge: no Release PR, because ci: is a hidden type. After this lands, let the title check report on one PR, then add 👮 Conventional PR title to the required checks on main.

Review instructions

The uv.lock jsonpath reads @.name.value, not @.name. GenericToml parses with release-please's TaggedTOMLParser, so every scalar is {value, start, end} and a filter on the bare key never matches; the plain form fails silently with a warning in the log and no file change.

Summary by CodeRabbit

  • New Features

    • Added automated pull request title validation using conventional commit formatting.
    • Introduced automated release management with release pull requests, version updates, testing, tagging, and PyPI publishing.
    • Added support for explicit release versions, hotfix procedures, and retrying failed publications.
  • Documentation

    • Updated release guidance to reflect automated workflows and revised versioning rules.
    • Added release history for versions 4.3.0 through 6.1.0.
    • Removed the changelog’s “Unreleased” heading.
  • Chores

    • Replaced the previous manual release process with automated release management.

The bump script derived the version from the merged PR title, committed
pyproject.toml locally so the tag pointed at a correct tree, and pushed the tag
without ever updating the default branch. pyproject.toml on main therefore drifted
to 4.1.0 while PyPI is at 6.1.0, and uv.lock carries the same stale self-version.

release-please keeps the bump in a reviewable Release PR instead, so the version
files on main match the release. Config uses the python strategy with a TOML
extra-file for the uv.lock self-entry, and include-component-in-tag false to keep
the vX.Y.Z tag shape.

bootstrap-sha is the main commit v6.1.0 was released from: the tag itself sits on
the bump commit the old workflow created off-branch, so release-please cannot find
it by walking main.

Publishing chains inside the release run rather than triggering on the release
event, because a GitHub Release created with GITHUB_TOKEN starts no new workflow.
The workflow file name and the pypi environment are unchanged, which is what
PyPI Trusted Publishing binds to.

The install verification cannot fail, so it gives no signal.

The || fallback catches every failure, including a missing or broken artifact on PyPI. The step always succeeds and only prints a warning. A retry loop that fails after the last attempt distinguishes index propagation delay from a real publish problem.

Review addressed. Both must-fix items and all five should-fix are fixed; replies are on each thread.

The two items with no line to sit on:

DEVELOPMENT.md:69-79 deleted in e8614a9, replaced with a pointer to the README and a line saying not to tag or publish by hand, with the manifest-drift reason.

pr_title.yml's synchronize trigger. Kept, and the check deliberately not added to the required list. Making a status check required changes merge gating for everyone on the repo, which is a team decision rather than something to fold into this PR. synchronize stays so the check is already reporting on head SHAs on the day someone does make it required, and it matches getstream-go, where it is required. One six-second job per push until then.

The other cosmetics: rm -rf dist dropped, and bug: no longer releasing is accepted, since the title lint rejects it anyway.

Repo settings changed outside the diff, now identical to getstream-go: allow_merge_commit: false, allow_rebase_merge: false, squash_merge_commit_title: PR_TITLE, squash_merge_commit_message: BLANK. Without these the PR title never reaches release-please and feat!: silently ships a minor. Reverting is one API call if the team wants merge commits back, but then this whole flow mis-versions.

Passing a ref into run_tests.yml gave CodeQL four high cache-poisoning alerts:
the reusable workflow checks out that ref and then populates the uv cache the
default branch reuses. The input is unreachable from untrusted data here, but it
is a real class and not worth carrying for the edge it closed.

The tests run on the workflow's own commit again, and the release job refuses to
tag when that is not the commit the pending Release PR would be tagged at. On the
path that gets there, a push of the Release PR's merge, they are the same commit,
so the guarantee is stronger than the ref input gave: the tagged tree is always a
tree the suite ran on.
ci.yml triggered on both push and pull_request, so every PR commit ran the suite
twice on the same SHA. On 3613936 the two runs started five seconds apart and the
pull_request one failed three legs on live-API 500s and read timeouts while the
push one passed, which is the shared-app race in its plainest form.

pull_request covers PR branches, and on the merge ref rather than the branch tip.
main and *.x are covered by release.yml, which runs this same reusable workflow as
the gate before tagging.
