Why

A chart release publishes a new version; nothing moves the self-managed stack's pin to it. That is done by hand today.

The failure mode is silence: a chart releases, nothing in the stack resolves to it, no pin moves, and the run goes green. A bumper that iterates only over what it understands reproduces that exactly.

What changed

tools/stack-pin-resolver (Go) plus .github/workflows/stack-pin-bump.yml, which runs on release: published and opens a PR on a fixed chore/stack-pin-bumps branch.

Resolution, all from data already in the repo:

released tag   deploy/helm/<dir>/v<version>
-> chart path  deploy/helm/<dir>
-> chart name  service_name of the matching entry in github-release-subprojects.json
-> stack pins  helmfile releases naming that chart

The released tag carries the version, so there is no "newest version" lookup and no ordering question.

A helmfile names a chart three ways. The third is not resolvable by reading the file:

form example resolution
explicit chart: nvcf/helm-reval that chart
convention no chart: line helm-nvcf-<release name>
override-with-default chart: {{ $v | default "nvcf/helm-nvcf-llm-request-router" | quote }} the default
anything else templated chart: {{ include "x" . }} unresolved, error

--audit enumerates the whole stack and exits non-zero on any unresolved release. bump refuses entirely while anything is unresolved, since the release nobody can read might be the one pinning this chart.

Testing

Current stack: 24 releases, 0 unresolved.

16 tests, mutation tested; 11 mutants die:

mutant killed by
unresolved release no longer fails the audit 1
bump proceeds past an unresolved release 1
unknown template form guessed by convention 2
versionless blocks counted as pins 1
rewrite keyed on version value, not release 2
chart nobody pins reported as success 1
missing service_name silently accepted 1
explicit chart: line ignored 4
default-override not followed 7
already-pinned release rewritten anyway 1
any tag accepted, not just chart releases 1

Two workflow bugs, found by running the step body under bash -e (how GitHub invokes run:):

  • git diff --quiet was repo-wide while the commit stages only deploy/stacks/self-managed/helmfile.d. Any unrelated modified file sets changed=true, then the commit aborts with nothing staged.
  • Checkout defaulted to the tagged commit; the PR targets main, so a stale stack would land on a branch cut from today's main.

Implementation notes

Go, not Python, per tools/AGENTS.md. The port is not mechanical in one place: the Python split release blocks with a regex ending in the lookahead (?=^\s+- name:|\Z), and Go's RE2 has no lookahead. Blocks are found line by line, which also yields each pin's line number, so the rewrite replaces one exact line and refuses if that line is no longer a version pin.

tools/ci/stack-pin-resolver builds the binary rather than go run: go run -C leaves the process in the tool's directory (cannot find the helmfiles), and go run does not propagate exit status.

Notes

Merging a generated PR moves the stack pin only. It does not deploy.

Github commit:
feat(ci): open a pull request bumping stack pins when a chart releases

Co-authored-by: Balaji Ganesan bganesan@nvidia.com

Summary by CodeRabbit

  • New Features

    • Added automated detection and updating of Helm chart version pins when releases are published or runs are started manually.
    • Added auditing for unresolved, unsupported, or invalid stack release references.
    • Added dry-run support to preview pin updates before applying them.
    • Added automatic pull request creation or refresh for proposed stack pin changes.
  • Bug Fixes

    • Improved handling of quoted and v-prefixed versions.
    • Prevented updates when any stack release cannot be resolved safely.
    • Preserved file permissions and formatting when updating pins.

The generated commit type is load-bearing

The generated commit is fix(stack):, not chore(stack):. deploy/stacks/self-managed is itself a release subproject, and tools/ci/github-release feeds RELEASE_RULES to semantic-release where chore carries "release": false. release-tags.yml runs github-release auto on every push to main with NVCF_GITHUB_AUTO_TAGGING_ENABLED=true and NVCF_GITHUB_RELEASE_DRY_RUN=false, so a chore commit would move the pin on main without ever cutting a stack release, and nothing downstream would see it.

Where this sits in the cascade

This is the last hop. #1222 handles service release to chart bump; publishing the chart release that follows is what triggers this workflow. Merges are the only manual gate in the chain; the nvcf-internal dispatcher carries a published stack release onward on a 5 minute poll.

Nine of the twenty-four chart versions pinned in the self-managed stack
are behind what has been released. The edit is one line each, so the cost
is not the work, it is remembering to do it.

On release: published for a deploy/helm/<chart>/v* tag, this resolves the
stack releases pinning that chart, rewrites their version, and opens or
refreshes a pull request.

The released tag carries the version, so there is no newest-version
lookup and none of the ordering questions that come with one.

Resolution uses only data already declared: the tag gives the chart path,
tools/ci/github-release-subprojects.json maps that path to the published
chart name, and the helmfile names the chart in one of three forms. The
third form was the interesting one. Two releases set chart to a Go
template with a default, and the default names the real chart, so those
resolve rather than being guessed at or skipped.

The failure this is built against is silence: a chart releases, nothing
resolves to it, no pin moves, and the run goes green. That is how
nvcf-unbound went unpublished. So the resolver enumerates every release
in the stack, an unresolvable one is an error rather than a skipped
iteration, and a bump refuses to run at all while any release is
unreadable, since the one it cannot parse might be the one that pins this
chart.

Fourteen behavioral cases, and the suite was mutation tested to confirm
it bites: skipping unresolved releases, bumping anyway on an unreadable
stack, guessing a chart name instead of raising, and rewriting every
version line rather than the target block are each caught by the case
that names them. The last matters most, since two releases currently sit
at the same version and a sloppy substitution would move the wrong one.

The tests run in this workflow rather than somewhere it might not reach.

📝 Walkthrough

Walkthrough

The PR replaces the Python stack-pin resolver with a Go CLI and adds tests for resolution and pin updates. A GitHub Actions workflow audits released Helm charts, updates stack pins, and creates or refreshes a pull request.

Changes

Stack pin automation

Layer / File(s) Summary
Resolver parsing and metadata contracts
tools/stack-pin-resolver/go.mod, tools/stack-pin-resolver/metadata.go, tools/stack-pin-resolver/stack.go
The Go module loads release metadata, parses Helmfile releases, resolves supported chart declarations, and validates pin rewrite targets.
Audit, bump, and behavioral validation
tools/stack-pin-resolver/main.go, tools/stack-pin-resolver/main_test.go, tools/stack-pin-resolver/.gitignore
The CLI audits resolution and updates matching chart pins. Tests cover supported inputs, unresolved releases, validation errors, no-op updates, byte preservation, and complete stack resolution.
Release-triggered workflow orchestration
tools/ci/stack-pin-resolver, .github/workflows/stack-pin-bump.yml
The Bash wrapper builds the Go resolver. The workflow filters chart releases, runs tests and audits, updates scoped stack files, pushes chore/stack-pin-bumps, and creates or updates a pull request.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to ad090

The automation can still silently omit valid Helmfile releases, allowing generated bump pull requests to miss required stack pins and undermine the purpose of this change. That issue should be fixed or explicitly accepted before merge; automated commits and pull requests also use a fixed personal identity.

In @.github/workflows/stack-pin-bump.yml:
- Around line 101-105: Update the workflow’s branch-handling sequence so the
target PR branch is fetched and checked out before the resolver performs audit
or mutation, ensuring existing bumps for the same chart are part of the working
tree. Remove reliance on applying a potentially conflicting stash after
checkout, and add a regression test covering an existing branch with an earlier
bump for the same pin.
- Around line 95-96: Update the workflow’s git identity configuration by
removing the private nvcf-release-bot name and service email, and use the
repository’s approved public automation identity or managed configuration
instead.
- Around line 134-140: Replace the gh pr view, gh pr edit, and gh pr create
calls in the workflow with gh api or an equivalent repository-controlled HTTP
client that supports custom headers, forwarding the W3C traceparent value on
every GitHub API request while preserving the existing pull-request lookup,
update, and creation behavior.
- Around line 55-58: Update the “Select the tag” and “Apply the bump” workflow
steps to pass tag values through the step env as TAG and read $TAG in Bash
instead of interpolating GitHub expressions into shell source. Validate TAG
against the expected chart-tag grammar before writing or using it, while
preserving the existing pull-request step’s safe env handling.

In `@tools/ci/stack-pin-resolver`:
- Around line 51-53: Update RELEASE_RE and the load_stack parsing flow to
recognize releases only at the releases-list indentation, excluding nested
entries such as set items. Expand VERSION_RE or its handling to accept quoted
versions and versions with trailing comments; when a version cannot be read,
mark the release unresolved rather than skipping it. Add fixtures covering
nested - name entries and quoted versions.

In `@tools/ci/test-stack-pin-resolver`:
- Around line 83-92: Update the chart-resolution assertions in the loop over
alpha, beta, and gamma so each release is matched against its exact expected
chart name, not merely the presence of “->”. Preserve the existing pass/fail
reporting while ensuring an incorrect chart mapping sets fail=1.

Two problems found while wiring the same shape for chart bumps.

git diff --quiet was repo-wide while the commit that follows stages only
deploy/stacks/self-managed/helmfile.d. Any unrelated modification in the
workspace sets changed=true, and the commit then aborts with nothing
staged.

Checkout took the release event's default of the tagged commit, but the
pull request targets the default branch, so pinning against the tag's
tree would carry whatever the stack looked like then onto a branch cut
from today's main.

tools/AGENTS.md asks for Go over Python for non-trivial repo tooling:
structured parsing, file transforms, and logic that benefits from unit
tests. Some CI environments here do not guarantee Python. This is all
three, so it should not have been Python to begin with.

The port is not mechanical in one place. The Python split helmfiles into
release blocks with a single regex ending in a lookahead, "up to the next
release or end of file", and Go's regexp engine has no lookahead. Blocks
are now found line by line, which is closer to the file anyway: it also
yields the line number of each pin, so the rewrite replaces one exact
line rather than reconstructing a block around it, and refuses if that
line is no longer a version pin when it goes to write.

Behaviour is unchanged: the checked-in stack audits to the same 24
releases, 0 unresolved.

tools/ci/stack-pin-resolver stays as the entrypoint. It builds the binary
rather than using `go run`, for the repository root (`go run -C` leaves
the process in the tool's own directory, where it can find neither the
helmfiles nor the release metadata) and for the exit status, which
`go run` does not propagate: it prints "exit status N" and exits 1.

setup-go derives its version from tools/go-toolchain/go.mod, since
tools/ci/check-go-version fails any workflow that pins a literal.

Sixteen tests, mutation tested. Eleven mutants die, including an
unresolved release that no longer fails the audit, a bump that proceeds
past one, an unknown template form guessed at by convention, versionless
blocks counted as pins, a rewrite keyed on the version value rather than
the release, and a chart nobody pins reported as success.

Seven findings from review, each verified against the code first.

Resolver:

The version out of a release tag was written verbatim into a shipped
helmfile after matching only `.+`. Anyone who can push a tag chooses that
value, so a space, a quote or a path traversal would corrupt the file or
smuggle in an adjacent key. It is now validated as a plain version before
anything is written.

The version pin was matched at any indent, so a `version:` nested inside
a values block could be taken as the release's pin and rewritten while
the real pin stayed put. Matching is now restricted to the release's own
field indent.

A release-level `version:` that could not be parsed was skipped silently,
which drops a real pin. That is the failure this tool exists to prevent,
so it is now reported as unresolved. A quoted value is also recognised;
nothing in the stack is quoted today, but gaining quotes must not
silently remove a pin from every future bump.

Workflow:

The bump was applied on the default branch and then stashed across a
checkout of the pull request branch, with `stash pop || true`. Whenever
the branch already carried a bump for the same pin, that conflicts, and
the swallowed failure either drops the earlier bump or commits conflict
markers. The branch is now checked out before the bump runs, which also
makes the run idempotent: the resolver sees the current value and reports
"already <version>".

The release tag was expanded into the run: body through `${{ }}`, the
standard Actions injection shape for a value an outside contributor can
choose. It is passed through env.

Generated commits carried a fixed `Co-authored-by` trailer naming one
person, so every future automated bump would be attributed to them in
published history. Removed. The committer identity is now the standard
github-actions[bot] rather than a private service account.

`gh pr edit` fails against this repository with "Projects (classic) is
being deprecated ... (repository.pullRequest.projectCards)", so refreshing
an existing pull request would have failed on every run after the first.
Replaced with the REST endpoint, which has no such dependency.

Four new tests, mutation tested; each of the four resolver behaviours
above dies when removed. The nested-key fixture puts the nested version
before the release's own pin: ordered the other way the loop finds the
real pin first and the test passes with the indent check deleted, which
mutation testing caught.

Declined: forwarding W3C traceparent on gh API calls, as this job makes
three calls in a workflow that already has run-level tracing.

Addressed. Each finding was reproduced against the code before changing anything.

Fixed

finding what was actually wrong
Validate the tag version before writing it the version matched .+ and was written verbatim into a shipped helmfile. Anyone who can push a tag chooses it, so a space, quote or ../ would corrupt the file or smuggle in an adjacent key. Now validated as a plain version first.
Restrict parsing to release-level fields the pin regex matched any indent, so a version: nested in a values: block could be rewritten as the pin while the real pin stayed put. Now restricted to the release's own field indent.
Do not silently omit valid Helmfile releases a release-level version: that would not parse was skipped silently, which drops a real pin. Now reported as unresolved. Quoted values are recognised too.
Check out the PR branch before applying the bump the bump ran on the default branch and was stashed across a checkout, with stash pop || true. If the branch already carried a bump for the same pin that conflicts, and the swallowed failure drops the earlier bump or commits conflict markers. The branch is now checked out first, which also makes the run idempotent.
Pass tag values through env done.
Remove the private automation identity now github-actions[bot]. Also removed the hardcoded Co-authored-by from generated commits, which would have attributed every future automated bump to one person in published history.

Four new tests, mutation tested. The nested-key fixture puts the nested version: before the release's own pin: ordered the other way the loop finds the real pin first and the test passes with the indent check deleted. Mutation testing caught that.

One more, not from review: gh pr edit fails against this repository with Projects (classic) is being deprecated ... (repository.pullRequest.projectCards). Refreshing an existing PR would have failed on every run after the first. Switched to the REST endpoint.

Stack still audits 24 releases, 0 unresolved.

Declined

  • Forward W3C traceparent on the gh calls. Three API calls in a workflow that already has run-level tracing; the plumbing costs more than it returns.
  • tools/ci/test-stack-pin-resolver:92 (assert the resolved chart name) is against a file that no longer exists; the bash suite was replaced by Go tests, which do assert the resolved chart name.

Restrict release parsing to direct children of releases.

A nested values entry with - name: can terminate its parent release before the actual pin. A nested chart: can also override the release chart identity. This can skip a pin or update a pin for the wrong chart.

  • tools/stack-pin-resolver/stack.go#L66-L72: pass the release field indentation into ChartNameForRelease and ignore nested chart: fields.
  • tools/stack-pin-resolver/stack.go#L172-L183: identify the releases list and split only entries at that list's entry indentation. Add nested - name: and nested chart: fixtures.

Forward W3C trace context on every GitHub request.

The gh api requests do not set a traceparent header. gh pr create cannot set custom headers. Pass trace context through env, add it with gh api -H, and replace gh pr create with a POST request through gh api.

As per coding guidelines, "Propagate trace context on all outbound HTTP and gRPC calls. Use W3C Trace Context headers."

Do not interpolate the tag into Bash source.

The tag is event-controlled. A quote or shell metacharacter in a manual-dispatch tag can terminate the assignment at line 69 and execute commands with this job's write permissions.

Pass the source tag through step env. Read it from $TAG. Do not write the raw tag through GITHUB_OUTPUT; pass it through env again in later steps.

Assess release-automation diagram coverage. This workflow connects chart publication to resolver execution, branch commit and push, and pull request creation or refresh. docs/dev/architecture.md covers product request flows, while docs/dev/github-release-process.md does not cover this stack-pin flow. Add or update a sequence diagram if release automation is in scope for the architecture documentation.

- Around line 24-26: Update versionValueRE so it accepts either a fully bare
version value or a value enclosed by matching quotes, rejecting values with only
an opening or closing quote. Add coverage for both unmatched-quote forms and
preserve the existing accepted version formats used by LoadStack and WritePin.

Comment thread tools/stack-pin-resolver/stack.go Outdated
The version pattern made the quote optional at each end independently, so
it accepted `version: "1.0.0` and `version: 1.0.0"`. Both are malformed
YAML, and both were classified as resolved pins, which meant the rewrite
replaced the line and quietly laundered the error away instead of
stopping and reporting it.

Bare, or quoted on both ends, and nothing else. Two tests cover the
unmatched forms and assert nothing is written for them; a third covers
the four accepted forms. Reverting the pattern kills both.

deploy/stacks/self-managed is itself a release subproject, and
tools/ci/github-release feeds RELEASE_RULES to semantic-release where
chore carries "release": false. release-tags.yml runs `github-release
auto` on every push to main with auto tagging enabled and dry run off, so
a generated commit of `chore(stack): pin <chart>` moved the pin on main
without ever cutting a stack release. Nothing downstream would see it.

Now `fix(stack):`, which cuts a patch release of the stack.
