actions/checkout v3 ref input default pull_request branch event default branch

💡 Result:

For the actions/checkout action (including version v3), the ref input behaves according to the following logic: When checking out the repository that triggered the workflow, the ref input defaults to the reference or SHA associated with that event [1][2]. If it is not triggered by an event, or in cases where the reference is not automatically determined, it defaults to the repository's default branch [1][2]. Regarding the pull_request event specifically: By default, actions/checkout checks out a merge commit that represents the merge between the pull request branch and the base branch, rather than the pull request head commit itself [3][4]. Because this merge commit is a detached HEAD, users who specifically want to work with the branch head or a different reference must explicitly set the ref input, for example by using ${{ github.head_ref }} [5][6]. In the context of the pull_request_target event, the action defaults to the base repository's default branch for security reasons, as this event runs in a context that has access to secrets [3].

GitHub Actions workflow_dispatch inputs branch ref checkout default branch

💡 Result:

To use the workflow_dispatch trigger with custom inputs and handle branch references or default branch checkouts in GitHub Actions, observe the following requirements and behaviors. Workflow Trigger Requirements The workflow_dispatch event trigger only functions when the workflow file is present on the repository's default branch [1][2]. If you attempt to trigger it manually via the GitHub UI or API while the workflow file exists only on a non-default branch, the workflow will not be available to run [2][3]. Handling Branch References When you manually trigger a workflow via the GitHub UI, you can select the branch or tag to run against. When using the GitHub CLI (gh) or REST API, you must specify the branch/ref explicitly using the --ref flag or the ref request parameter [2]. Checkout Behavior The actions/checkout action is responsible for cloning your code into the runner [4]. Its behavior regarding the branch is as follows: - By default, if the ref input is omitted, actions/checkout checks out the reference (branch, tag, or SHA) that triggered the workflow [4][5]. - If you have manually triggered the workflow on a specific branch (e.g., feature-branch), actions/checkout will default to that branch [4]. - If you specifically require the default branch regardless of what triggered the workflow, you must explicitly set the ref input in your checkout step: - uses: actions/checkout@v7 with: ref: main # Replace 'main' with your actual default branch name Summary of Workflow Dispatch inputs - Inputs are defined in the workflow file under on.workflow_dispatch.inputs and are accessible within the workflow via the inputs context (or github.event.inputs) [1]. - These inputs are independent of the branch reference [1]. Whether you run the workflow on the default branch or a feature branch, the same set of inputs will be available to the workflow [1]. If you are using third-party actions like benc-uk/workflow-dispatch to trigger workflows across different repositories, you may need to explicitly pass the ref input to ensure the target workflow operates on the correct branch, especially if the target repository has a different default branch than the caller [6][7].

actions/checkout persist-credentials default true local Git configuration persist-credentials false

💡 Result:

The persist-credentials input for the GitHub Actions checkout action (actions/checkout) determines whether the repository's authentication token or SSH key is configured in the local Git configuration [1][2]. The default value for persist-credentials is true [1][2]. When set to true (the default), the action configures the authentication credentials into the local Git configuration, which allows your workflow steps to run authenticated Git commands (such as git fetch or git push) automatically [1][3]. The action ensures these credentials are removed during the post-job cleanup process [1][4]. When you set persist-credentials to false, the action will not configure these credentials in the local Git configuration [1][2]. This is an optional setting used to opt-out of this behavior [1][5]. Note: While there have been discussions and community requests to change this default to false to further reduce the risk of credential exposure, the current authoritative configuration in the official actions/checkout repository maintains the default value as true [1][6][2]. Recent security improvements have been implemented to store these credentials in a separate file under $RUNNER_TEMP rather than directly in.git/config, while still allowing git commands to work seamlessly without requiring workflow changes [3][7].

Platane/snk v3 GitHub Action Docker entrypoint script source

💡 Result:

The Platane/snk v3 GitHub Action does not use a traditional entrypoint script file. Instead, the Docker container is configured to run a specific command directly [1]. As specified in the project's Dockerfile, the container uses the following instruction to execute the application: CMD ["bun", "/action-release/index.js"] The Docker container environment is built using Bun, and the entry point for the action's logic is the JavaScript file located at /action-release/index.js [1]. This file contains the bundled code generated during the project's build process [1]. Users do not need to interact with this entrypoint file directly, as it is managed automatically by the GitHub Action's Docker configuration [2][1].

Platane/snk v3 github.com/Dockerfile CMD bun /action-release/index.js action.yml Docker run uses Dockerfile

💡 Result:

Platane/snk is a popular GitHub Action that generates an animated snake game visualization based on a user's GitHub contribution graph [1][2]. The action supports both GIF and SVG output formats [1][3]. Regarding the specific components you mentioned: Dockerfile and CMD: The project uses a Dockerfile that leverages the bun runtime (specifically oven/bun) [4]. The final image is configured with the command CMD ["bun", "/action-release/index.js"], which executes the main action logic upon container startup [4]. action.yml: The action definition file (action.yml) specifies that the action runs using a docker container [5]. It points to a specific image reference (image: docker://platane/snk@sha256:...) to ensure a consistent, versioned execution environment [5]. Usage: Users can invoke this action in their GitHub workflow files using the syntax - uses: Platane/snk@v3 [1][6]. For users who only require SVG output and prefer a faster, non-Docker implementation, the project also provides a secondary action: uses: Platane/snk/svg-only@v3 [3][7].

GitHub Hosted Runners Node.js Runtime Removed v12 v16 actions/checkout deprecation

💡 Result:

GitHub Actions has removed support for older Node.js runtimes as they reached their end-of-life (EOL). The removal of Node.js 12 and Node.js 16 followed established deprecation cycles, requiring users and action maintainers to upgrade their dependencies to newer, supported versions [1][2][3]. Summary of Node.js Runtime Deprecations in GitHub Actions: Node.js 12: Support was removed from GitHub Actions runners on August 14, 2023, following a deprecation process that began in 2022 [2][4][5]. Node.js 16: After reaching EOL, Node.js 16 was removed from GitHub Actions runners on November 12, 2024 [1][3]. Node.js 20: Following the EOL of Node.js 20 in April 2026, it was removed from GitHub runner images by May 2026, with defaults migrated to Node.js 22 [6]. Impact on actions/checkout: The actions/checkout action, like many other official actions, required updates to align with these runtime changes. When Node.js 12 and 16 were deprecated, older versions of actions/checkout (such as v2 or early v3 releases) that relied on these runtimes triggered deprecation warnings in user workflows [7][8]. To resolve these warnings and ensure continued functionality, users were required to update to newer versions of the action (e.g., updating to v3 or v4) that had been refactored to run on the then-current supported Node.js version [7]. Recommendation: To avoid issues with runtime deprecations, users should always use the latest major version of official actions, such as actions/checkout@v4. You can verify which runtime an action uses by checking its action.yml file in its respective GitHub repository [9]. It is recommended to follow the official GitHub Changelog to stay informed about upcoming deprecation timelines for runner runtimes [1][10].

actions/checkout v3 Node16 action.yml

💡 Result:

The actions/checkout@v3 action uses the Node.js 16 runtime [1][2]. GitHub transitioned away from Node.js 16 to Node.js 20 in GitHub Actions [3], leading to deprecation warnings for actions that rely on the older runtime, including actions/checkout@v3 [3][4][5]. While actions/checkout@v3 remains technically functional (and has received recent security-related backports in version v3.7.0) [6][7], it is recommended to upgrade to actions/checkout@v4 or later to use an action that runs on a supported Node.js version [3][4][5]. You can view the specific configuration for v3 in its official action.yml file on GitHub [8]. To address deprecation warnings, simply update your workflow configuration from: - uses: actions/checkout@v3 to: - uses: actions/checkout@v4 (or the latest available major version) [5].

GitHub hosted runners removal node16 ubuntu-latest November 12 2024

💡 Result:

GitHub announced that Node.js 16 would reach its end-of-life on the Actions runner on November 12, 2024 [1]. From this date forward, Node.js 16 was no longer included in the GitHub-hosted runners, and users were required to migrate their actions to Node.js 20 to avoid workflow disruption [1]. While the general end-of-life date for the runner was set for November 12, 2024 [1], the specific removal dates from various runner images varied slightly: - Ubuntu 24.04: Node.js 16 was removed on October 21, 2024 [2]. - Ubuntu 20.04 and 22.04: Node.js 16 was scheduled for removal on November 18, 2024 [3]. This transition was part of a larger deprecation process that began earlier in 2024 [4]. By late 2024, GitHub had completed the transition to Node.js 20 as the required runtime for GitHub Actions [1].
