ci: pin actionlint version and add pre-commit hook - #54
Pin CI and pre-commit to actionlint 1.7.12 for consistent workflow validation.
Add the pinned actionlint pre-commit hook and a wrapper that skips ShellCheck on Darwin to avoid actionlint's pipe deadlock; Linux CI retains ShellCheck.
Preserve the existing actionlint commit without including the separate guardrail changes.
Dependencies
This PR contains one commit directly above upstream/main and changes only the CI workflow, pre-commit configuration, and actionlint wrapper. It is independent of the guardrail PR and can merge in either order.
Validation
Pre-commit checks passed for all three changed files before pushing.
The complete commit diff and branch tracking were inspected.
git diff --check passed.
CI: Pin the actionlint workflow step to version 1.7.12.
Pre-commit: Add the rhysd/actionlint hook at v1.7.12, with verbose output enabled.
Platform handling: Add a wrapper that disables ShellCheck on Darwin to avoid an actionlint pipe deadlock. On other platforms, it passes arguments to actionlint unchanged.
The CI workflow and pre-commit hook now use actionlint version 1.7.12. The hook invokes a Bash wrapper that disables ShellCheck on Darwin and forwards arguments to actionlint.
Changes: Actionlint Integration
Layer / File(s)
Summary
Configure and invoke actionlint .github/workflows/ci.yaml, .pre-commit-config.yaml, scripts/pre-commit/actionlint.sh
CI specifies actionlint version 1.7.12. The pre-commit hook uses the same version and invokes a wrapper that disables ShellCheck on Darwin. The wrapper forwards arguments to actionlint.
Developers with an older local Go toolchain can be blocked from validating workflow changes. Pin the hook's Go version before merging.

- Line 53: Set the actionlint hook’s language_version to Go 1.25.0 in the
pre-commit configuration so its environment uses the toolchain required by
actionlint v1.7.12 instead of the system Go version.

L0: # pre-commit
L1:
L2: A framework for managing and maintaining multi-language pre-commit hooks.
L3:
L4: 【0†Star†github.com】
L5:
L6: 【1†Introduction】 【2†Installation】 【3†Adding plugins】 【4†Usage】 【5†Creating new hooks】 【6†Command line interface】 【7†Advanced features】 【8†Contributing】
L7: # Introduction 【9†¶】
L8:
L9: Git hook scripts are useful for identifying simple issues before submission to code review. We run our hooks on every commit to automatically point out issues in code such as missing semicolons, trailing whitespace, and debug statements. By pointing these issues out before code review, this allows a code reviewer to focus on the architecture of a change while not wasting time with trivial style nitpicks.
L10: As we created more libraries and projects we recognized that sharing our pre-commit hooks across projects is painful. We copied and pasted unwieldy bash scripts from project to project and had to manually change the hooks to work for different project structures.
L11: We believe that you should always use the best industry standard linters. Some of the best linters are written in languages that you do not use in your project or have installed on your machine. For example scss-lint is a linter for SCSS written in Ruby. If you’re writing a project in node you should be able to use scss-lint as a pre-commit hook without adding a Gemfile to your project or understanding how to get scss-lint installed.
L12: We built pre-commit to solve our hook issues. It is a multi-language package manager for pre-commit hooks. You specify a list of hooks you want and pre-commit manages the installation and execution of any hook written in any language before every commit. pre-commit is specifically designed to not require root access. If one of your developers doesn’t have node installed but modifies a JavaScript file, pre-commit automatically handles downloading and building node to run eslint without root.
L13: # Installation 【10†¶】
L14:
L15: Before you can run hooks, you need to have the pre-commit package manager installed.
L16:
L17: Using pip:
L18:
L19: pip install pre-commit
L20:
L21:
L22: In a python project, add the following to your requirements.txt (or requirements-dev.txt):
L23:
L24: pre-commit
L25:
L26:
L27: As a 0-dependency 【11†zipapp†docs.python.org】:
L28:
L29: * locate and download the `.pyz` file from the 【12†github releases†github.com】
L30: * run `python pre-commit-#.#.#.pyz ...` in place of `pre-commit ...`
L31:
L32: ## Quick start 【13†¶】
L33: ### 1. Install pre-commit 【14†¶】
L34:
L35: * follow the 【2†install】 instructions above
L36: * `pre-commit --version` should show you what version you're using
L37:
L38: $ pre-commit --version
L39: pre-commit 4.7.0
L40: ### 2. Add a pre-commit configuration 【15†¶】
L41: * create a file named `.pre-commit-config.yaml`
L42: * you can generate a very basic configuration using 【16†`pre-commit sample-config`】
L43: * the full set of options for the configuration are listed 【3†below】
L44: * this example uses a formatter for python code, however `pre-commit` works for any programming language
L45: * other 【17†supported hooks】 are available
L46:
L47: repos:
L48: - repo: https://github.com/pre-commit/pre-commit-hooks
L49: rev: v2.3.0
L50: hooks:
L51: - id: check-yaml
L52: - id: end-of-file-fixer
L53: - id: trailing-whitespace
L54: - repo: https://github.com/psf/black
L55: rev: 22.10.0
L56: hooks:
L57: - id: black
L58: ### 3. Install the git hook scripts 【18†¶】
L59:
L60: * run `pre-commit install` to set up the git hook scripts
L61:
L62: $ pre-commit install
L63: pre-commit installed at .git/hooks/pre-commit
L64:
L65:
L66: * now `pre-commit` will run automatically on `git commit`!
L67: ### 4. (optional) Run against all the files 【19†¶】
L68: * it's usually a good idea to run the hooks against all of the files when adding new hooks (usually `pre-commit` will only run on the changed files during git hooks)
L69:
L70: $ pre-commit run --all-files

L92: # Adding pre-commit plugins to your project 【21†¶】
L93:
L94: Once you have pre-commit installed, adding pre-commit plugins to your project is done with the `.pre-commit-config.yaml` configuration file.
L95:
L96: Add a file called `.pre-commit-config.yaml` to the root of your project. The pre-commit config file describes what repositories and hooks are installed.
L97: ## .pre-commit-config.yaml - top level 【22†¶】
L98: 【23†`repos`】 | A list of 【24†repository mappings】.
L99: 【25†`default_install_hook_types`】 | (optional: default `[pre-commit]`) a list of `--hook-type`s which will be used by default when running 【26†`pre-commit install`】.
L100: 【27†`default_language_version`】 | (optional: default `{}`) a mapping from language to the default 【28†`language_version`】 that should be used for that language. This will only override individual hooks that do not set 【28†`language_version`】. For example to use `python3.7` for `language: python` hooks:
L101:
L102: default_language_version:
L103: python: python3.7
L104: 【29†`default_stages`】 | (optional: default (all stages)) a configuration-wide default for the 【30†`stages`】 property of hooks. This will only override individual hooks that do not set 【30†`stages`】. For example:
L105:
L106: default_stages: [pre-commit, pre-push]
L107: 【31†`files`】 | (optional: default `''`) global file include pattern.
L108: 【32†`exclude`】 | (optional: default `^$`) global file exclude pattern.
L109: 【33†`fail_fast`】 | (optional: default `false`) set to `true` to have pre-commit stop running hooks after the first failure.
L110: 【34†`minimum_pre_commit_version`】 | (optional: default `'0'`) require a minimum version of pre-commit.
L111:
L112: A sample top-level:
L113:
L114: exclude: '^$'
L115: fail_fast: false
L116: repos:
L117: - ...
L118: ## .pre-commit-config.yaml - repos 【24†¶】
L119:
L120: The repository mapping tells pre-commit where to get the code for the hook from.
L121:
L122: 【35†`repo`】 | the repository url to `git clone` from or one of the special sentinel values: 【36†`local`】, 【37†`meta`】.
L123: 【38†`rev`】 | the revision or tag to clone at.
L124: 【39†`hooks`】 | A list of 【40†hook mappings】.
L125:
L126: A sample repository:
L127:
L128: repos:
L129: - repo: https://github.com/pre-commit/pre-commit-hooks
L130: rev: v1.2.3
L131: hooks:
L132: - ...
L133: ## .pre-commit-config.yaml - hooks 【40†¶】
L134:
L135: The hook mapping configures which hook from the repository is used and allows for customization. All optional keys will receive their default from the repository's configuration.
L136: 【41†`id`】 | which hook from the repository to use.
L137: 【42†`alias`】 | (optional) allows the hook to be referenced using an additional id when using `pre-commit run <hookid>`.
L138: 【43†`name`】 | (optional) override the name of the hook - shown during hook execution.
L139: 【28†`language_version`】 | (optional) override the language version for the hook. See 【44†Overriding Language Version】.
L140: 【45†`files`】 | (optional) override the default pattern for files to run on.
L141: 【46†`exclude`】 | (optional) file exclude pattern.
L142: 【47†`types`】 | (optional) override the default file types to run on (AND). See 【48†Filtering files with types】.
L143: 【49†`types_or`】 | (optional) override the default file types to run on (OR). See 【48†Filtering files with types】.
L144: 【50†`exclude_types`】 | (optional) file types to exclude.
L145: 【51†`args`】 | (optional) list of additional parameters to pass to the hook.
L146: 【30†`stages`】 | (optional) selects which git hook(s) to run for. See 【52†Confining hooks to run at certain stages】.
L147: 【53†`additional_dependencies`】 | (optional) a list of dependencies that will be installed in the environment where this hook gets run. One useful application is to install plugins for hooks such as `eslint`.
L148: 【54†`always_run`】 | (optional) if `true`, this hook will run even if there are no matching files.
L149: 【55†`verbose`】 | (optional) if `true`, forces the output of the hook to be printed even when the hook passes.
L150: 【56†`log_file`】 | (optional) if present, the hook output will additionally be written to a file when the hook fails or 【55†verbose】 is `true`.
L151: One example of a complete configuration:
L152:
L153: repos:
L154: - repo: https://github.com/pre-commit/pre-commit-hooks
L155: rev: v1.2.3
L156: hooks:
L157: - id: trailing-whitespace
L158:
L159:
L160: This configuration says to download the pre-commit-hooks project and run its trailing-whitespace hook.
L161: ## Updating hooks automatically 【57†¶】
L162:
L163: You can update your hooks to the latest version automatically by running 【58†`pre-commit autoupdate`】. By default, this will bring the hooks to the latest tag on the default branch.
L164: # Usage 【4†¶】
L165:
L166: Run `pre-commit install` to install pre-commit into your git hooks. pre-commit will now run on every commit. Every time you clone a project using pre-commit running `pre-commit install` should always be the first thing you do.
L167:
L168: If you want to manually run all pre-commit hooks on a repository, run `pre-commit run --all-files`. To run individual hooks use `pre-commit run <hook_id>`.
L169: The first time pre-commit runs on a file it will automatically download, install, and run the hook. Note that running a hook for the first time may be slow. For example: If the machine does not have node installed, pre-commit will download and build a copy of node.
L170:
L171: $ pre-commit install
L172: pre-commit installed at /home/asottile/workspace/pytest/.git/hooks/pre-commit

L189:
L190: pre-commit currently supports hooks written in 【60†many languages】. As long as your git repo is an installable package (gem, npm, pypi, etc.) or exposes an executable, it can be used with pre-commit. Each git repo can support as many languages/hooks as you want.
L191:
L192: new in 2.5.0: `pre-commit` sets the `PRE_COMMIT=1` environment variable during hook execution.
L193:
L194: The hook must exit nonzero on failure or modify files.
L195: A git repo containing pre-commit plugins must contain a `.pre-commit-hooks.yaml` file that tells pre-commit:
L196: 【61†`id`】 | the id of the hook - used in pre-commit-config.yaml.
L197: 【62†`name`】 | the name of the hook - shown during hook execution.

<title>Go Toolchains - The Go Programming Language</title>
<location>https://go.dev/doc/toolchain</location>
<excerpt>citeturn0search0 [wordlim: 200] Crawled: today; The `GOTOOLCHAIN` environment setting can force a specific Go version, overriding the `go` and `toolchain` lines. ... Some commands incorporate new module versions as part of their operation: `go get` adds new module dependencies to the main module; `go work use` adds new local modules to the workspace; `go work sync` resynchronizes a workspace with local modules that may have been updated since the workspace was created; `go install package@version` and `go run package@version` effectively run in an empty main module and add `package@version` as a new dependency.
The `go get` command manages the Go toolchain dependency just as it manages dependencies on other modules. For example, `go get go@latest` updates the module to require the latest released Go toolchain.
The `GOTOOLCHAIN` environment setting can force a specific Go version, overriding the `go` and `toolchain` lines. For example, to test a package with Go 1.21rc3:
`GOTOOLCHAIN=go1.21rc3 go test
`
The default `GOTOOLCHAIN` setting is `auto`, which enables the toolchain switching described earlier. The alternate form `<name>+auto` sets the default toolchain to use before deciding whether to switch further. For example `GOTOOLCHAIN=go1.21.3+auto` directs the `go` command to begin its decision with a default of using Go 1.21.3 but still use a newer toolchain if directed by `go` and `toolchain` lines. Because the default `GOTOOLCHAIN` setting can be changed with `go env -w`, if you have Go 1.21.0 or later installed, then
`go env -w GOTOOLCHAIN=go1.21.3+auto
`
is equivalent to replacing your Go 1.21.0 installation with Go 1.21.3.
Before Go 1.21, toolchains did not require a module or workspace to have a `go` line greater than or equal to the `go` version required by each of its dependency modules.
## The `GOTOOLCHAIN` setting
The `go` command selects the Go toolchain to use based on the `GOTOOLCHAIN` setting. To find the `GOTOOLCHAIN` setting, the `go` command uses the standard rules for any Go environment setting:
* If `GOTOOLCHAIN` is set to a non-empty value in the process environment (as queried by `os.Getenv`), the `go` command uses that value.
* Otherwise, if `GOTOOLCHAIN` is set in the user’s environment default file (managed with `go env -w` and `go env -u`), the `go` command uses that value.
* Otherwise, if `GOTOOLCHAIN` is set in the bundled Go toolchain’s environment default file (`$GOROOT/go.env`), the `go` command uses that value.
In standard Go toolchains, the `$GOROOT/go.env` file sets the default `GOTOOLCHAIN=auto`, but repackaged Go toolchains may change this value.
If the `$GOROOT/go.env` file is missing or does not set a default, the `go` command assumes `GOTOOLCHAIN=local`.
Running `go env GOTOOLCHAIN` prints the `GOTOOLCHAIN` setting.
## Go toolchain selection
At startup, the `go` command selects which Go toolchain to use. It consults the `GOTOOLCHAIN` setting, which takes the form `<name>`, `<name>+auto`, or `<name>+path`. `GOTOOLCHAIN=auto` is shorthand for `GOTOOLCHAIN=local+auto`; similarly, `GOTOOLCHAIN=path` is shorthand for `GOTOOLCHAIN=local+path`. The `<name>` sets the default Go toolchain: `local` indicates the bundled Go toolchain (the one that shipped with the `go` command being run), and otherwise `<name>` must be a specific Go toolchain name, such as `go1.21.0`. The `go` command prefers to run the default Go toolchain. As noted above, starting in Go 1.21, Go toolchains refuse to run in workspaces or modules that require newer Go versions. Instead, they report an error and exit.
When `GOTOOLCHAIN` is set to `local`, the `go` command always runs the bundled Go toolchain.
When `GOTOOLCHAIN` is set to `<name>` (for example, `GOTOOLCHAIN=go1.21.0`), the `go` command always runs that specific Go toolchain. If a binary with that name is found in the system PATH, the `go` command uses it. Otherwise the `go` command uses a Go toolchain it downloads and verifies.
When `GOTOOLCHAIN` is set to `<name>+auto` or `<name>+path` (or the shorthands `auto` or `path`), the `go` command selects and runs a newer Go version as needed. Specifically, it consults the `toolchain` and `go` lines in the current workspace’s `go.work` file or, when there is no workspace, the main module’s `go.mod` file. If the `go.work` or `go.mod` file has a `toolchain <tname>` line and `<tname>` is newer than the default Go toolchain, then the `go` command runs `<tname>` instead. If the file has a `toolchain default` line, then the `go` command runs the default Go toolchain, disabling any attempt at updating beyond `<name>`. Otherwise, if the file has a `go <version>` line and `<version>` is newer than the default Go toolchain, then the `go` command runs `go<version>` instead.
To run a toolchain other than the bundled Go toolchain, the `go` command searches the process’s executable path (`$PATH` on Unix and Plan 9, `%PATH%` on Windows) for a program with the given name (for example, `go1.21.3`) and runs that program. If no such program is found, the `go` command downloads and runs the specified Go toolchain. Using the `GOTOOLCHAIN` form `<name>+path` disables the download fallback, causing the `go` command to stop after searching the executable path.
Running `go version` prints the selected Go toolchain’s version (by running the selected toolchain’s implementation of `go version`).
Running `GOTOOLCHAIN=local go version` prints the bundled Go toolchain’s version.
Starting in Go 1.24, you can trace the `go` command’s toolchain selection process by adding `toolchaintrace=1` to the `GODEBUG` environment variable when you run the `go` command.

Is it possible that pre-commit's `golang` language support just updated to Go 1.25? That would explain why installing the Go 1.24 packages in my Amazon Linux 2023-based containers resolved the issue.

## Overriding language version ¶
Sometimes you only want to run the hooks on a specific version of the language. For each language, they default to using the system installed language (So for example if I’m running `python3.7` and a hook specifies `python`, pre-commit will run the hook using `python3.7`). Sometimes you don’t want the default system installed version so you can override this on a per-hook basis by setting the `language_version`.
- repo: https://github.com/pre-commit/mirrors-scss-lint
rev: v0.54.0
hooks:
- id: scss-lint
language_version: 2.1.5
This tells pre-commit to use ruby `2.1.5` to run the `scss-lint` hook.
Valid values for specific languages are listed below:
* python: Whatever system installed python interpreters you have. The value of this argument is passed as the `-p` to `virtualenv`.
* on windows the pep394 name will be translated into a py launcher call for portability. So continue to use names like `python3` (`py -3`) or `python3.6` (`py -3.6`) even on windows.
* node: See nodeenv.
* ruby: See ruby-build.
* rust: `language_version` is passed to `rustup`
* new in 3.0.0 golang: use the versions on go.dev/dl such as `1.19.5`
you can set `default_language_version` at the top level in your configuration to control the default versions across all hooks of a language.
default_language_version:
# force all unspecified python hooks to run python3
python: python3
# force all unspecified ruby hooks to run ruby 2.1.5
ruby: 2.1.5

When matching workflow files are present, pre-commit uses the system Go by default. With Go 1.24.5 and GOTOOLCHAIN=local, installing actionlint v1.7.12 fails because it requires Go 1.25.0.
Pre-commit's Go backend downloads and uses the requested Go version, so this setting supplies Go 1.25.0 even when the developer's system toolchain is Go 1.24.5. A run with no matching workflow files is skipped before the hook environment is installed, so that case is not blocked.
