Summary

  • Add .github/workflows/snap-reusable.yml which fires on release: released (plus manual dispatch and workflow_call, matching winget/homebrew/aur workflows)
  • It resolves the latest release tag via the existing latest-release-info action and dispatches the Release snap workflow in hrzlgnm/mdns-browser-snap with that tag; that workflow already pins the snapcraft source-tag, builds, smoke-tests, and publishes to the stable channel

Setup required

  • A fine-grained PAT with Actions: read/write on hrzlgnm/mdns-browser-snap stored as the repository secret SNAP_REPO_TOKEN

Testing

  • actionlint .github/workflows/*.yml passes
  • End-to-end verification requires a published release once SNAP_REPO_TOKEN is configured

Summary by CodeRabbit

  • Chores
    • Added an automated workflow to trigger Snap package releases manually, from reusable workflows, or when a new release is published.
    • Snap releases now use the latest release tag and are dispatched to the downstream packaging workflow.

Dispatches the Release snap workflow in hrzlgnm/mdns-browser-snap
with the published tag, so the snap store package follows each
release without manual steps.

📝 Walkthrough

Walkthrough

The PR adds the Update Snap reusable workflow. It supports manual, reusable-workflow, and release triggers. It resolves the latest release tag and dispatches the downstream Snap release workflow.

Changes

Snap release automation

Layer / File(s) Summary
Snap release dispatch
.github/workflows/snap-reusable.yml
The workflow uses read-only checkout permissions, retrieves the latest release tag through a local action, and dispatches release.yml in hrzlgnm/mdns-browser-snap with the resolved tag.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to f0325

The new workflow can fail for reusable callers, trigger a snap release for the wrong version, or resolve release data from the wrong repository; it also leaves an unnecessary checkout credential persisted and uses an unpinned action reference. These bounded integration and security issues should be fixed before merging.

Poem

A release tag steps into light
The Snap workflow takes its flight
A reusable path is drawn
Dispatch begins at release dawn
One small file keeps builds in sight

Pin latest-release-info under the workflow policy.

This workflow file requires action references to use commit SHAs with version comments. Replace the relative reference with a repository-qualified reference pinned to a verified commit SHA, or document an approved local-action exception.

- Around line 7-10: Declare SNAP_REPO_TOKEN in the workflow_call
reusable-workflow contract so callers can explicitly provide the secret used by
GH_TOKEN before gh workflow run; preserve the existing secrets: inherit behavior
and other trigger definitions.
- Around line 23-30: Update the release tag assignment in the “Dispatch Release
snap” step to use github.event.release.tag_name for release-triggered runs,
while retaining the release-info output from the latest-release lookup for
manual and reusable invocations.
- Around line 18-21: Update the actions/checkout step to set persist-credentials
to false, while preserving the existing fetch-depth configuration.
- Around line 18-25: Update the checkout step to use the workflow repository and
workflow commit identified by job.workflow_repository and job.workflow_sha,
rather than the caller repository. Configure the latest-release-info action to
receive the host repository explicitly so it resolves the correct local action
and release data.

GitHub Actions reusable workflows workflow_call secrets explicit passing secrets inherit called workflow declaration

💡 Result:

In GitHub Actions, you can pass secrets to a reusable workflow using either explicit mapping or the secrets: inherit keyword [1][2]. These two methods are mutually exclusive; you cannot combine them in a single job call [3]. Explicit Secret Passing To pass secrets explicitly, you must map the caller's secrets to the names expected by the called workflow [4][5]. 1. In the reusable (called) workflow, you must declare the expected secrets under the on.workflow_call.secrets key [6][4][7]. 2. In the caller workflow, use the secrets key within the job to map your available secrets to those declared in the callee [6][5]. Example: # Callee (reusable workflow) on: workflow_call: secrets: MY_SECRET: required: true # Caller workflow jobs: call-reusable: uses:./.github/workflows/reusable.yml secrets: MY_SECRET: ${{ secrets.MY_SECRET }} Secrets: inherit The secrets: inherit keyword allows the calling workflow to implicitly pass all of its available secrets (repository, organization, or enterprise level) to the reusable workflow [1][2][5]. - This does not require declaring secrets in the callee's on.workflow_call.secrets definition, though it remains good practice to document them [1][2]. - It is designed primarily for use within the same organization or enterprise [1][2][8]. - It is not recursive; secrets are only passed to the directly called workflow [2][5]. If workflow A calls B, and B calls C, B must explicitly pass or inherit the secrets again for C to receive them [2][5][8]. Security and Best Practices - Principle of Least Privilege: Using secrets: inherit is often discouraged for non-trusted or external workflows because it exposes all of the caller's secrets to the called workflow [5][9][10]. - Explicit Mapping: Prefer explicit passing to limit the "blast radius" of potential secret exposure [9][11][10]. - Environment Secrets: Reusable workflows do not support passing environment secrets via on.workflow_call [1]. If an environment is specified at the job level in the reusable workflow, it will use the environment's secrets instead of any passed caller secrets [1].

Declare SNAP_REPO_TOKEN under workflow_call.

The job passes ${{ secrets.SNAP_REPO_TOKEN }} to GH_TOKEN before gh workflow run. An explicit caller cannot map this secret because the reusable-workflow contract does not declare it. Add the required secret declaration. Callers using secrets: inherit may continue to use inheritance.
