fix(release): stop cutting a release when only the dev tools moved - #354
Merged
Conversation
uv.lock carries the dev group, both images build with `uv sync --frozen --no-dev`, and the release trigger matched on the filename. So v1.36.4 shipped for a pytest, pytest-asyncio and ruff bump: 78 entries in site-packages, not one of them different from v1.36.3, and three containers restarted on the fleet for a version label. Dependency PRs land weekly, so that was the most frequent release the project cut. The manifests no longer trigger by name. scripts/runtime_deps_changed.py exports the no-dev resolution at both refs with the real resolver and compares, and release.yml builds on the answer. Replaying it over the two releases that prompted this: v1.36.3..v1.36.4 gives "Build UI: false, Build Worker: false", v1.36.2..v1.36.3 gives true for both, and an app/ change still builds the UI. Fail-safe by design. uv missing, a ref that will not resolve, an export that fails, a lock that disagrees with its pyproject -- every one of them answers "changed" and says why on stderr. A pointless image costs a build. A release that silently does not happen ships nothing while the run reports success, and this repo has been bitten by that before. One existing guard needed fixing to allow it. The fetch-tags rule decided a job runs the suite by searching its whole `run` block for "pytest", so the new comment explaining that a pytest bump used to cut a release read as a job that runs pytest. Comments are stripped now, with a control that a real suite job losing fetch-tags still goes red.

- Around line 70-71: Pin the uv installation in the release workflow’s “Install
uv” step to version 0.11.16, matching both Dockerfiles. Add a test that verifies
the workflow and both Dockerfiles consistently reference uv 0.11.16.
In `@scripts/runtime_deps_changed.py`:
- Around line 96-103: Update the TemporaryDirectory usage in the manifest
materialization flow to create its workspace under /data, and ensure the release
environment provisions the corresponding /data mount for this runtime data.
- Around line 80-92: Update the dependency comparison around the uv export
parser and its callers to use a canonical representation derived from uv.lock
that preserves artifact hashes and environment markers, rather than relying on
the --no-hashes export output or dropping indented hash continuation lines.
Ensure hash-only runtime lock changes are detected, and add coverage for that
case while preserving existing runtime dependency filtering behavior.

Two review findings, both real. Exporting with --no-hashes and keeping only the name==version lines compared less than the build consumes. A lock can gain or change an artifact for a version that already exists -- a new wheel for a platform, a re-resolved sdist -- and every pin still reads the same while `uv sync --frozen` installs something different. The comparison now keeps hashes and markers and drops only comment lines, which is 615 entries where it was 38. The new test tampers with one hash in a copy of the real lock and fails if that reads as no change. The detector also ran whatever uv pip installed, while both images build with 0.11.16, and uv only guarantees lockfile compatibility within a minor release. It now reads the version out of the Dockerfile rather than restating it, so there is no second copy to drift, and warns rather than fails if it cannot -- an unpinned uv still compares both refs with one binary, so the answer stays sound. A test keeps the Dockerfile readable and the two images in agreement. Answers are unchanged where it matters: v1.36.3..v1.36.4 still builds nothing, v1.36.2..v1.36.3 still builds both.

A dev-tool bump cut a full release. v1.36.4 shipped for pytest, pytest-asyncio and ruff, and its images were identical to v1.36.3: I pulled both and diffed
site-packages, 78 entries each, zero difference. Three containers restarted on the fleet for a version label. Dependency PRs land weekly, so this was the most frequent release the project cut.uv.lockcarries the dev group, both images build withuv sync --frozen --no-dev, and the trigger matched on the filename. The question that decides a release is not "did uv.lock change" but "did the no-dev resolution change".What this does
scripts/runtime_deps_changed.pyexports the no-dev resolution at both refs with the real resolver and compares them.pyproject.tomlanduv.lockno longer trigger a build by name; they gate that check, and the build follows its answer.Replayed over the two releases that prompted this:
Fail-safe is the whole design. uv missing from PATH, a ref that will not resolve, an export that fails, a lock that disagrees with its pyproject: every one answers "changed" and explains itself on stderr. A pointless image costs a build. A release that silently does not happen ships nothing while the run reports success, and that is the failure this repo has been bitten by twice.
One existing guard had to be fixed
The fetch-tags rule decided whether a job runs the suite by searching its entire
runblock for the string "pytest". My new comment explains that a pytest bump used to cut a release, so the guard read prose as a command and flagged the release job. Comments are stripped now. The control that keeps it honest: a real suite job losingfetch-tagsstill goes red, verified by removing it from test.yml.That is the same way the skip-marker guard in
test_beads_batch_65.pyonce fooled itself, so it is worth naming twice.Checks
Eleven mutations, each watched go red and then restored:
uv.locktriggers a build by name againfetch-tagsThe two behaviour tests run against real history,
v1.36.2,v1.36.3andv1.36.4, with a companion test that fails loudly if those tags are ever missing rather than passing on nothing.Full suite 4791 passed, 7 skipped, coverage 95.60%, ruff check and format clean.
