name: rcli Homebrew tap

# Keeps RunanywhereAI/homebrew-tap's Formula/rcli.rb pointing at the newest
# release. Nothing did this before, so the tap sat at 0.20.10 from 14 July while
# releases went on to 0.20.24: `brew install runanywhereai/tap/rcli` handed
# people a month-old CLI, which is what "brew install rcli doesn't work" was.
#
# This is a SEPARATE workflow on purpose. release.yml creates the GitHub Release
# as a DRAFT, and update-tap.sh reads the published .sha256 sidecars over HTTPS,
# so it cannot run inside that job — the assets are not downloadable yet. The
# `release: published` event fires when a human publishes the draft, which is
# exactly the moment the tarballs become fetchable. Keeping it out of
# release.yml also means a tap failure can never fail a release.

GitHub Actions concurrency one pending run replaces pending queue queue max concurrency YAML support

💡 Result:

In GitHub Actions, you can control how pending workflow runs are handled within a concurrency group using the queue property in your YAML configuration. By default, GitHub Actions uses queue: single [1][2]. In this mode, only one job or workflow run can be pending in a concurrency group at any time [1][2]. When a new run is queued for that group, any existing pending run is automatically canceled and replaced by the new one [1][2]. If you wish to allow multiple runs to wait in line rather than being canceled, you can set the queue property to max [1][2]. This configuration allows up to 100 jobs or workflow runs to be pending in the concurrency group simultaneously [1][3][2]. When the queue reaches this limit of 100, any subsequent incoming runs will be canceled [1][3][2]. It is important to note that the queue: max property cannot be used in combination with cancel-in-progress: true [2][4]. Attempting to use both in the same concurrency block will result in a workflow validation error because they represent conflicting strategies for managing in-progress and pending work [2][4]. Example YAML structure: concurrency: group: my-group-name queue: max cancel-in-progress: false # Required when using queue: max [2][4]

GitHub Actions concurrency queue max syntax official documentation

💡 Result:

In GitHub Actions, the concurrency configuration supports a queue property that allows you to manage how multiple workflow runs or jobs behave when they share the same concurrency group [1][2]. When you set queue: max, you enable the concurrency group to queue up to 100 pending jobs or workflow runs [3][1]. Once the queue reaches this limit, any additional jobs or workflow runs that attempt to enter the group are automatically canceled [1][2]. Key details regarding the queue property: - Default Behavior: By default, the queue property uses the value single. In this mode, only one job or workflow run can be pending in the concurrency group at a time; new incoming runs will cancel the existing pending run [1][2]. - Configuration: You can configure this within your workflow YAML file under the concurrency block [4]. - Conflict Constraint: The queue: max setting cannot be used in combination with cancel-in-progress: true [1][2]. Attempting to use both simultaneously will result in a workflow validation error [1][2]. - Limits: This feature allows for a maximum of 100 queued jobs or workflow runs per concurrency group [3][1]. For additional context on how this functions within your workflow syntax: concurrency: group: my-group-name queue: max # cancel-in-progress: true <-- Cannot be used with queue: max This functionality was introduced to help manage sequential execution for deployments and shared resource access more effectively [4].

Preserve pending tap-update runs.

cancel-in-progress: false retains the running job but replaces the existing pending run when a newer run enters the group. A manual inputs.version update can therefore be dropped before update-tap.sh runs.

Add queue: max when the target GitHub or GHES environment supports it. Otherwise, use a durable queue.

GitHub Actions job-level env variables available to JavaScript action process.env step-level env if condition secrets context

💡 Result:

In GitHub Actions, environment variables defined at both the job level and the step level are available to JavaScript actions via the standard Node.js process.env object [1]. When you define an environment variable in a workflow—whether in the job's env block or a specific step's env block—the runner automatically exposes these as environment variables to the underlying process execution [2][1]. Key implementation details include: 1. Job-level vs. Step-level Variables: Variables defined at the job level (jobs.<job_id>.env) are accessible to all steps within that job [3]. Variables defined at the step level (jobs.<job_id>.steps[*].env) are specific to that individual step [2][3]. Both will be populated in process.env for a JavaScript action executed in that context [1]. 2. Accessing Secrets in 'if' Conditions: The secrets context cannot be directly accessed within if conditional expressions [4][5]. Attempting to reference secrets.SECRET_NAME directly in an if condition will result in a parsing error (e.g., "Unrecognized named-value") [4][6]. 3. Recommended Workaround: To conditionally execute steps based on a secret's presence or value, you must first map the secret to an environment variable [4][5]. Example pattern: jobs: example_job: runs-on: ubuntu-latest env: # Map secret to an env variable at the job level HAS_SECRET: ${{ secrets.MY_SECRET!= '' }} steps: - name: Conditional Step if: env.HAS_SECRET == 'true' uses:./my-javascript-action env: # Pass the actual secret if needed by the action MY_SECRET: ${{ secrets.MY_SECRET }} By mapping the secret to an environment variable first, you allow the GitHub Actions runner to resolve the value before the if condition is evaluated, as env context variables are accessible in most workflow keys [7][6].

site:docs.github.com GitHub Actions secrets cannot be directly referenced in if conditional env job level

💡 Result:

It is correct that GitHub Actions secrets cannot be directly referenced in if conditionals [1][2]. This restriction applies because the if conditional is evaluated by GitHub Actions before the job is sent to a runner [3][4]. Because secrets are sensitive, they are not available to the evaluation engine in this context to prevent potential exposure [1][2]. If a secret is referenced directly in an if conditional, it will be evaluated as an empty string [1][2]. To work around this limitation, you can define the secret as an environment variable at the job level [1][2]. While you still cannot use that environment variable directly in a job-level if conditional (as the environment variable context is not typically available for job-level conditions), you can use it to conditionally execute specific steps within the job [1][2]. For example: jobs: my-job: runs-on: ubuntu-latest env: MY_SECRET_VAL: ${{ secrets.MY_SECRET }} steps: - name: Run only if secret is set if: ${{ env.MY_SECRET_VAL!= '' }} run: echo "Secret is present"

Scope TAP_TOKEN to the update step.

Line 44 makes the secret available to actions/checkout@v7 and all later steps. Only Update the tap needs the secret. Keep a non-secret presence flag at job scope, pass TAP_TOKEN through the update step, and use the flag in the verification condition.
