actions/checkout persist-credentials default true local git config README
💡 Result:
In the actions/checkout GitHub Action, the persist-credentials input defaults to true [1][2]. When enabled, this setting configures the repository to use the authentication token or SSH key provided to the action for subsequent Git commands within the same job [1][3]. Historically, this credential was stored directly in the local.git/config file of the checked-out repository [4][3]. However, as of version v6.0.0, the action was updated to improve security by storing these credentials in a separate file located in the $RUNNER_TEMP directory instead of the repository's.git/config [5][6][7]. The action then uses Git's includeIf configuration mechanism to conditionally apply these credentials only when interacting with the specific repository directory [8]. This persistence allows workflow scripts to run authenticated Git commands (such as git fetch, git push, etc.) automatically without requiring further configuration [1][6]. If you wish to opt out of this behavior, you can set persist-credentials to false in your workflow step [1][9]. The credentials are removed during the post-job cleanup process [1][4].

💡 Result:
In the actions/checkout v4 action, the persist-credentials input has a default value of true [1][2]. When enabled (which is the default), the action configures the authentication token or SSH key within the local git configuration [1][3], allowing subsequent git commands in your job to be authenticated [3][4]. When running inside a Docker container job, the actions/checkout action is designed to handle this configuration specifically to support the container environment [5]. The action creates a temporary credential file and uses git's includeIf configuration mechanism to point to this file, ensuring that the necessary credentials are available to the git process running inside the container at /github/workspace [5]. By default, the token or credentials are automatically removed during the post-job cleanup process [3][4]. You can set persist-credentials to false if you wish to opt-out of this behavior [3][4].

GitHub Actions container jobs workspace mounted actions checkout persist credentials .git/config
💡 Result:
When using actions/checkout in GitHub Actions, the persist-credentials input (which defaults to true) controls how Git authentication is handled for subsequent Git commands [1][2]. As of version 6.0.0, the mechanism for persisting these credentials changed to enhance security [2][3]. Instead of writing the authentication token directly into the local.git/config file, actions/checkout now saves the credentials to a separate file within the runner's temporary directory ($RUNNER_TEMP) [1][2]. It then uses Git's includeIf configuration feature to conditionally include this credential file only when working within the repository's directory [3][4]. For container jobs, this change requires the Actions Runner to be version 2.329.0 or later [2][5]. In these environments, the runner must correctly mount the $RUNNER_TEMP directory into the container to make the credentials file accessible to the containerized environment [6]. If the containerized step cannot resolve the path specified in the includeIf directive or if the runner does not perform the necessary volume mounting for the temporary directory, Git operations may fail to authenticate [6][4]. If you encounter issues where Git commands inside a container job fail to authenticate, ensure that your Actions Runner version is up to date [2][5]. If you continue to face limitations, setting persist-credentials: false allows you to opt out of this behavior, though you will then need to manage your own authentication credentials manually within the job [1][2].

Docker image reference without a tag defaults to latest tag mutable tags digest pin official documentation
💡 Result:
In Docker, when you refer to an image without specifying a tag, the Docker engine and the Dockerfile builder both default to the latest tag [1][2][3][4]. The latest tag is a mutable pointer [5][6]. This means the image it points to can be changed or replaced at any time by pushing a different image to the same repository with the same tag [7][6]. Because of this mutability, using latest—or any named tag—is generally discouraged for production environments where consistency and reproducibility are required [7][8][9][6]. To guarantee that you are running the exact same image consistently across different environments, you should use a digest pin [5][7][9]. A digest is a unique, immutable, content-addressed SHA-256 hash that identifies a specific image manifest [5][8][9][6]. When you pull or reference an image by its digest (e.g., repository@sha256:hash), Docker verifies that the downloaded image matches that hash [5][9]. This provides several critical advantages: 1. Immutability: Once an image is built and assigned a digest, that content cannot change [5][9]. 2. Security: It prevents supply chain attacks where a malicious actor might overwrite a mutable tag with a compromised image [5][9][6]. 3. Consistency: It ensures that the exact same artifact is deployed in development, testing, and production, eliminating discrepancies caused by tag updates [5][7][6]. For production environments, best practices include: - Pinning images in your Dockerfiles using the format repository@sha256:digest [7][8][6]. - Automating the updating of these pins using tools like Renovate or Dependabot to ensure you continue receiving security updates without sacrificing stability [7]. - Enabling tag immutability settings in your container registry (such as Amazon ECR or Harbor) to prevent existing tags from being overwritten, if your infrastructure requires the use of named tags [7][6].

site:semgrep.dev/docs semgrep/semgrep latest update Docker image digest
💡 Result:
The Docker image digest for semgrep/semgrep:latest is not a static value; it changes every time the image is updated and pushed to the registry. Because Docker digests are cryptographic hashes of the specific image manifest, they must be retrieved at the time of pull [1][2]. To find the current digest for the semgrep/semgrep:latest image, you can run the following command in your terminal: docker inspect --format='{{index.RepoDigests 0}}' semgrep/semgrep:latest Alternatively, if you have not pulled the image yet, you can fetch the current digest from the registry using: docker buildx imagetools inspect semgrep/semgrep:latest --format '{{json.Manifest.Digest}}' Using the:latest tag is generally discouraged for production environments because it is mutable and can lead to non-deterministic builds. It is recommended to use specific version tags (e.g., semgrep/semgrep:1.107.0) or pin to a specific digest to ensure your CI/CD pipelines remain consistent and secure [1][3]. You can view the list of available tags and their corresponding digests on the official Semgrep Docker Hub repository page.

Semgrep CLI --config p/typescript registry ruleset version pin immutable reference documentation
💡 Result:
The Semgrep CLI does not support version pinning or immutable references for Registry rulesets (e.g., p/typescript) directly within the --config flag [1][2]. When you use a Registry ruleset identifier like --config p/typescript, Semgrep dynamically fetches the latest version of that ruleset from the Semgrep Registry at runtime [1][3]. Because these rulesets are managed and updated by the Semgrep team (or third-party curators), they are not immutable; your scans may automatically include new or modified rules over time, which can lead to new findings even if your code remains unchanged [4][3]. To achieve version pinning or immutability, you must use one of the following manual workarounds: 1. Download the Ruleset as a Static File: You can manually download the YAML content of a ruleset and save it to your local environment [5]. curl https://semgrep.dev/c/p/typescript > typescript-ruleset.yml Once saved, use the local file path with the --config flag: semgrep scan --config typescript-ruleset.yml. This ensures you are using a static, immutable version of the rules until you manually update the local file [5]. 2. Use Git/Version Control: If you commit the downloaded ruleset file to your repository, you effectively pin the rules to a specific version (a specific commit SHA in your repository), ensuring consistent behavior across environments and over time [5]. While individual rules support min-version and max-version fields in their YAML configuration to ensure compatibility with specific Semgrep CLI versions, this mechanism does not pin the ruleset content itself against registry updates [6].

site:semgrep.dev/docs semgrep registry ruleset pin version --config p/typescript
💡 Result:
It is not possible to pin a specific version of a Semgrep Registry ruleset (such as p/typescript) directly via the --config flag in the CLI [1][2][3]. When you use --config p/typescript, Semgrep fetches the most recent version of those rules from the Semgrep Registry at the time of execution [1]. Because these rulesets are maintained and updated regularly, your policy will automatically include new rules or modifications to existing rules without any action required on your part [1][4]. If you require consistent, repeatable scan results that do not change due to Registry updates, you must use one of the following approaches: 1. Download the Ruleset: Manually download the specific version of the ruleset file (e.g., in YAML format) from the Registry or repository, save it within your project repository, and reference that local file in your scan command [2][3]: semgrep scan --config path/to/your/pinned_ruleset.yaml 2. Use Semgrep AppSec Platform (Policy Management): If you are using the Semgrep AppSec Platform, you can define specific Detection Policies that manage which rules are active [5]. While the underlying rulesets from the registry may still receive updates, the Platform provides control over which rules are enabled and how they behave (e.g., Monitor vs. Block), providing a more stable environment than using the CLI's --config registry shortcut [4][5]. Using local configuration files is the most effective way to ensure that your scan results remain identical across different environments and over time [2].
