The release workflow now runs once for each commit pushed to main, so a newer push no longer cancels a queued release. The download resolver now uses the first 7 characters of the commit SHA, which is the same SHA length that CI uses for the release tags. Together these changes fix 404s for prebuilt binary downloads (#892).

---

Why downloads return 404

A plugin checkout without a release tag on HEAD makes its download URL from {version}-nightly.{sha}. This URL fails in two ways:

Cause	Example	Fix in this PR
No release for the commit: a newer push cancelled the queued run	15 of the last 150 main commits	Concurrency group per SHA on main
SHA length mismatch: git rev-parse --short returns more characters on a full clone than on CI's shallow checkout	0.11.1-nightly.73539711 returns 404, CI created 0.11.1-nightly.7353971 (200)	Use the first 7 characters of the full SHA

Note

All 560 existing prerelease tags use 7-character SHAs, so the resolver matches every existing release.

Workflow changes

• On main the concurrency group includes github.sha, so each commit gets its own run. Branch and PR runs keep the shared group, and a new push still cancels the previous run there.
• The rolling nightly tag moves only when the run's commit is still the tip of main, because runs can now finish out of order.
• The trigger and the npm job no longer include the stale fix/npm-pulish branch. version.lua no longer includes the stale fix/download-version branch.

Important

Each burst of pushes to main now builds every commit, which uses more runner time (macOS included).

What this PR does not fix

The other 17 of the 32 missing releases have different causes:

• 12 commits had no run. For example, 11 PRs merged on 2026-10-19 within 6 seconds arrived as one push, and only the tip e577666 got a release.
• 5 commits had a failed release build.

A user whose plugin is pinned to one of these commits still falls back to cargo build.

Tests

• tests/version_spec.lua: a new spec sets core.abbrev=12 and checks that the release tag uses the first 7 characters of HEAD. The spec fails on main and passes with this change. make test-version has 14 passed tests.
• I ran the resolver on a full clone of current main: before this change 0.11.1-nightly.73539711 (404), after this change 0.11.1-nightly.7353971 (200).
• The workflow YAML parses. The workflow changes take effect only on a push to main.

Summary by CodeRabbit

• Bug Fixes

  • Nightly tags are updated only when a release run is for the latest commit on the main branch, preventing older runs from overwriting them.
  • Nightly version identifiers consistently use the first seven characters of the commit reference.
  • The download-version branch is classified as a development prerelease.
  • Older nightly publish runs use a separate history tag.

• Chores

  • Release workflows run on pushes to main and version tags, rather than the fix/npm-pulish branch. Publishing runs are queued by ref.

Walkthrough

The release workflow updates its push filters, concurrency groups, nightly tag handling, and npm publish tags. Version resolution uses a fixed seven-character SHA prefix and changes nightly branch classification.

Changes: Release and version handling

Layer / File(s)	Summary
Version identifier and branch classification lua/fff/utils/version.lua, tests/version_spec.lua	M.resolve derives a seven-character identifier from the full HEAD SHA. Only main and detached HEAD follow the nightly path. The integration test checks the prefix when Git uses a 12-character abbreviation.
Release triggers, concurrency, and publish tags .github/workflows/release.yaml	Push triggers and npm publishing no longer include fix/npm-pulish; main and version tags remain eligible. Main-branch concurrency groups include the commit SHA, and release and npm-publish jobs queue runs by ref. The release job skips moving the nightly tag when the run SHA differs from the current main tip. The npm-publish job selects nightly-history for nightly runs that are not at that tip and uses the selected tag for all package publish steps.

Merge Risk: High · previous review 84991

Release execution may be blocked entirely, and concurrent PyPI uploads can mix artifacts from different commits. Both issues should be fixed before merging.

Pre-merge checks: 5

Check name	Status	Explanation
Description Check		Check skipped - CodeRabbit’s high-level summary is enabled.
Title check		The title clearly describes the main change: preventing 404 errors for prebuilt binaries from main commits.
Docstring Coverage		Docstring coverage is inconclusive: files from earlier reviews still need to be rechecked within the check's analysis limits. Not blocking.
Linked Issues check		Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check		Check skipped because no linked issues were found for this pull request.

Major · Serialize PyPI uploads. Main runs can now upload the same version… · release.yaml:765

.github/workflows/release.yaml:765
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Serialize PyPI uploads. Main runs can now upload the same version concurrently.

Each main commit now has its own workflow concurrency group, and pypi-publish has no concurrency key. Two main runs can therefore reach the upload step together. Both build wheels for fff-search 0.11.0 and both use skip-existing: true. PyPI does not allow replacing an existing filename, so one release can mix wheels from different commits. The base shared one group for main, which queued these uploads. Add a job-level concurrency group to serialize them.

🐛 Suggested fix

   pypi-publish:
     name: Publish Python wheels to PyPI
     needs: [build-python, build-python-sdist]
+    concurrency:
+      group: pypi-publish
+      queue: max
     runs-on: ubuntu-latest
