fix(release): render stack inventories that pin a chart released after the cut by kristinapathak · Pull Request #2974 · NVIDIA/nvcf

kristinapathak · 2026-10-28T07:02:16Z

Why

The stack inventory renders each pinned source chart from its release tag and requires that tag to be in the stack's history. That is the component-tag trust boundary from #1779: the inventory only renders chart source that went through review, not whatever commit a hand-pushed tag points at. The umbrella manifest and bundle, the docs catalog, and github-release tag all rely on the inventory's source fields.

A patch on a stack release branch can legitimately move a pin to a chart version released after the branch cut, from main or from that chart's maintenance branch. That tag is not in the stack's history, so the inventory fails for the patch. See #2972.

What changed

When a pinned chart tag is outside the stack's history, and outside the snapshot source added in fix(release): open stack trains with a mergeable bump and an inventory #2971, docs-version-sync accepts it if origin/main or the chart's maintenance branch for that minor, origin/release-<tag prefix>X.Y, contains the tag. Both are reviewed branches.
Any other tag still fails: a tag on an unmerged branch, on another chart's maintenance branch, or on the wrong minor's branch. The existing chart path and Chart.yaml checks still run.
The inventory schema is unchanged. The branch an out-of-history chart came from is logged to stderr.
docs/dev/github-release-process.md describes the rule and notes that chart maintenance branches must be kept after tagging.

This branch is stacked on #2971 and includes its commit until #2971 merges. Review the last commit, fix(release): render stack inventories that pin a chart released after the cut.

Testing

go test ./..., go vet ./..., and gofmt -l in tools/docs-version-sync: pass. The three new accept cases fail without the fix; the new reject cases pass with it.
git diff --check: clean.
No QA needed: release tooling only.

Notes

The tag workflow runs the tooling from the tagged commit, so each release branch that pins source charts needs this change too. The self-managed v1.1 train pins source charts (backport in fix(release): accept source charts from the 1.1 train snapshot source #2973 carries the fix(release): open stack trains with a mergeable bump and an inventory #2971 part). The compute-plane v1.0 train pins the nvca-operator chart and has neither change. The self-managed v1.0 train pins no source charts.
The release workflow checks out the full history with every branch, which this check depends on.

Summary by CodeRabbit

New Features
- Stack patches can now pin chart releases published after the stack train was cut, provided the chart tag is available on the default branch or its matching maintenance branch. Unavailable or unrelated chart tags are rejected.
Documentation
- Updated maintenance guidance to recommend submitting stack pin updates through reviewed pull requests after verifying component artifacts.
- Clarified that chart maintenance branches should be retained after tagging so stack inventories can use the chart release.

branch-cut built the next-train VERSION bump on the release branch snapshot. The snapshot copies the default branch tree onto a parent from before the first merge in its history, so the bump shared no recent history with the default branch. Its pull request conflicted and listed the whole repository as changed. Build the bump on the selected default-branch commit instead, on both the create and reuse paths. That history includes the default branch's merges, so the bump branch moves from release-bump/ to chore/release-train/, outside the release-* names that the release ruleset holds to a linear history. The tag workflow's stack inventory requires every pinned source chart tag to be an ancestor of the stack commit. Chart tags released from the default branch are never ancestors of a snapshot, so the first release of a train rooted at a snapshot could not produce its inventory. The snapshot now records the selected commit in a Snapshot-Of trailer. The inventory also accepts a chart tag that is an ancestor of that commit, after confirming the commit holds the snapshot's tree. A snapshot cut before the trailer existed is matched to a commit with the same tree. A chart tag outside both histories is still rejected.

…r the cut The stack inventory renders each source chart from its release tag and requires that tag to be in the stack's history, so the chart source it renders is reviewed source and not whatever commit a tag points at. A patch on a stack release branch that moves a pin to a chart version released after the train was cut fails that check: the new tag comes from the default branch or from a chart maintenance branch, neither of which the train contains. The tag workflow then stops before it creates the stack's GitHub Release. When a pinned chart tag is outside the stack's history, accept it if origin/main or the chart's maintenance branch for the tag's minor, origin/release-<tag prefix>X.Y, contains it. The tag workflow's full-history checkout fetches every branch. A tag on any other branch, including another chart's maintenance branch or the wrong minor's, is still rejected. The chart path and Chart.yaml name checks at the tag are unchanged, and the inventory schema is unchanged. The render log names the branch that supplied the chart.

Walkthrough

Inventory materialization now accepts source-chart tags found on origin/main or the matching chart maintenance branch when they are outside the stack commit’s lineage. It rejects tags absent from those branches. The release-process documentation describes the branch rules and maintenance-pin guidance.

Full details: Title check

Explanation

The title follows Conventional Commits format with one scoped type, fix(release):. It accurately describes the primary change: allowing stack inventories to render charts released after the stack cut.

Full details: Linked Issues check

Explanation

For [#2972], materializeResolvedInventorySourceCharts accepts a pinned chart tag from the stack history, the validated snapshot source, origin/main, or the matching chart maintenance branch. It preserves chart-path and Chart.yaml checks. It rejects tags found only on unmerged branches, another chart's maintenance branch, the wrong minor branch, or unavailable tags. The added tests cover these acceptance and rejection cases.

Full details: Out of Scope Changes check

Explanation

The implementation directly addresses [#2972]. The tests verify the new source-chart rules. The documentation records the reviewed-branch rule and the required retention of chart maintenance branches. These changes support the linked issue and introduce no unrelated product or schema changes.

State the tooling prerequisite for existing train branches.

If a train branch predates this change, its tag workflow runs the old docs-version-sync from the stack tag. That validator still rejects a post-cut chart tag. Tell maintainers to backport this tooling to the train branch before merging the pin update. (raw.githubusercontent.com)

Preserve source-chart provenance in the resolved inventory.

The new branch check allows a post-cut chart tag to reach publication, but the inventory still records only publishedChartRepository/name and release.Version. It does not record the source tag or resolved chart commit. The separate release manifest records the stack source identity, not the source-chart identity. This creates a provenance gap for the newly accepted pins.
