GitHub Actions checkout persist-credentials default documentation softprops action-gh-release token default

💡 Result:

For the actions/checkout action, the persist-credentials input defaults to true [1][2][3]. When set to true, the action configures the local Git client with the provided authentication token (or SSH key), enabling your workflow scripts to run authenticated Git commands (such as git push or git pull) [1][2][3]. The token is stored in the local Git configuration and is removed during the post-job cleanup phase [1][2][3]. You can opt-out of this behavior by explicitly setting persist-credentials: false in your workflow YAML [1][2]. For the softprops/action-gh-release action, the token input defaults to ${{ github.token }} when omitted [4][5][6]. This utilizes the built-in GITHUB_TOKEN provided by GitHub Actions for the workflow job [4][5][6]. A non-empty explicit token value will override this default [4][5][6]. If you need to pass an empty string to treat the token as explicitly unset, you should avoid passing it as an input or use an expression to handle the logic, as passing an empty string literally can be treated differently depending on the implementation [5][6][7]. Note that if you are running workflows on the release event, you may need a personal access token (PAT) instead of the default GITHUB_TOKEN, as the default token does not trigger subsequent workflows [5][6][8].

Citations:


Pin workflow actions and disable checkout credential persistence.

Because this workflow grants contents: write, pin all three actions to verified full commit SHAs. Set persist-credentials: false for actions/checkout. softprops/action-gh-release already defaults token to ${{ github.token }}, so an explicit token is optional.

golang.org/x/mod/semver documentation valid versions leading zeros prerelease empty identifiers

💡 Result:

The golang.org/x/mod/semver package implements semantic versioning with specific rules and behaviors described in its documentation and source code [1][2]. Leading Zeros Major, minor, and patch components must be decimal integers without extra leading zeros (e.g., "v01.0.0" is invalid) [2]. Regarding pre-release identifiers, the package follows the Semantic Versioning 2.0.0 specification, which dictates that numeric pre-release identifiers must not include leading zeros [2][3][4]. The package enforces this through parsing logic that rejects numeric identifiers with leading zeros [3]. Prerelease and Empty Identifiers A semantic version string accepted by this package follows the form vMAJOR[.MINOR[.PATCH[-PRERELEASE][+BUILD]]] [2]. - Prerelease: A pre-release string starts with a hyphen [5][2]. It consists of a series of dot-separated identifiers [2]. - Empty Identifiers: The package follows the rule that pre-release and build metadata identifiers must not be empty [2][3][4]. The internal parsing functions (such as parsePrerelease and parseBuild) explicitly check for empty identifiers between dots or surrounding hyphens/plus signs and will return an invalid status if they are found [3]. The package maintains strict adherence to these rules to ensure compatibility within the Go module ecosystem [2]. While it generally follows SemVer 2.0.0, it includes two specific deviations: it mandates a leading "v" prefix (e.g., "v1.0.0"), and it supports vMAJOR and vMAJOR.MINOR as shorthand for vMAJOR.0.0 and vMAJOR.MINOR.0, respectively [2].

suggestion (bug_risk): Suppressing curl failures completely may hide useful diagnostics if proxy warming fails

All three curl calls use || true, so persistent proxy or sum.golang.org failures (e.g., bad module path or misconfig) will be completely silent in the workflow logs. Consider at least surfacing non-2xx responses (e.g., via -sS and a custom error message) or limiting || true to known transient/expected failures so you retain useful diagnostics when something is actually wrong.

Go module proxy protocol .info .mod .zip pkg.go.dev indexing source download behavior

💡 Result:

The Go module proxy protocol is a simple, stateless HTTP-based API that allows the go command to retrieve module information and source code from servers called module proxies [1][2]. Proxies serve content via GET requests to specific endpoints, meaning they can be implemented as simple web servers or even static file systems [1][2]. The standard endpoints defined by the protocol are: - /{module}/@v/list: Returns a list of all known versions for a module, one per line [2]. - /{module}/@v/{version}.info: Returns a JSON-encoded file containing metadata about the module version, such as the exact version string and timestamp [3][4]. - /{module}/@v/{version}.mod: Returns the content of the module's go.mod file [3][2]. If the original module lacks a go.mod file, the proxy is expected to provide a synthetic one [5][6]. - /{module}/@v/{version}.zip: Returns the module source code as a ZIP archive [3][4]. Each file in the zip must be prefixed with the module path and version (e.g., example.com/mod@v1.0.0/) [2]. The Go command uses the GOPROXY environment variable to determine which proxies to contact [5][6]. When resolving a module, it checks the defined proxies in order; if a requested file returns a 404 or 410, it typically moves to the next configured proxy [5][6]. Regarding indexing and pkg.go.dev: - Indexing: The service index.golang.org maintains a public feed of new module versions that become available on proxy.golang.org [7][8]. - Discovery: Pkg.go.dev monitors this index to discover new modules [9][10]. A worker process consumes these updates, downloads the corresponding module source code from proxy.golang.org using the module proxy protocol, and processes it to extract documentation, licenses, and other metadata for the website [9][10]. - User Requests: If a module is not yet indexed, users can trigger discovery by visiting the module's page on pkg.go.dev and clicking a "Request" button, which initiates the process [10]. In summary, the protocol provides a standardized, efficient way to distribute Go modules, while pkg.go.dev leverages the index service and proxy mirror to automate the discovery and documentation of the Go ecosystem [7][9][10].

site:go.dev/ref/mod module proxy .zip pkg.go.dev index module version download

💡 Result:

The Go module proxy protocol defines a specific URL structure for downloading module source code as a zip archive. To download a specific version of a module from a proxy server (such as proxy.golang.org), you can perform an HTTP GET request to the following endpoint: //@v/.zip In this URL pattern: - is the module path (often with characters escaped if they contain uppercase letters). - is the semantic version of the module. For example, to download version v1.0.0 of a module named example.com/my/mod, the request URL would be: https://proxy.golang.org/example.com/my/mod/@v/v1.0.0.zip The module proxy protocol also supports other endpoints for retrieving information, such as: - //@v/.info: Returns JSON metadata about the version. - //@v/.mod: Returns the go.mod file for that version. - //@latest: Returns the latest version of the module. When using these endpoints, note that the Go command-line tool manages these interactions automatically based on the GOPROXY environment variable [1]. If you are interacting with the proxy manually, ensure that any uppercase letters in the module path are replaced with their lowercase equivalent preceded by an exclamation mark (e.g., example.com/User/Mod becomes example.com/!user/!mod).

site:go.dev/ref/mod "go mod download" "-json" errors exit status

💡 Result:

When running go mod download -json, the Go command provides module information in JSON format for successful operations [1]. If the command encounters an error, it exits with a non-zero status code [1]. In Go, when a command fails, it reports an error message to standard error (stderr). If you are using the -json flag, the command is intended to output structured information; however, if the command fails, the output may be incomplete, or the error details may be printed to stderr instead of being encapsulated within the JSON stream. Common causes for go mod download failures include: 1. Missing or inconsistent information in go.mod or go.sum files [1]. 2. Network issues or unavailability of modules through configured proxies in GOPROXY [1]. 3. Multiple modules providing the same package, or no modules found for a requested package [1]. To resolve errors, you can typically use the go mod tidy command to update and correct your go.mod and go.sum files [1]. If you encounter specific issues, ensure that your environment's GOPROXY settings are correctly configured to reach the required module repositories [1].

site:go.dev/ref/mod proxy.golang.org pkg.go.dev index.golang.org source zip module version

💡 Result:

The services proxy.golang.org, pkg.go.dev, and index.golang.org play distinct roles in the Go module ecosystem: proxy.golang.org This is an official module proxy server maintained by Google. When the go command needs to download a module, it checks the proxy defined by the GOPROXY environment variable [1]. The proxy acts as a cache and a reliable source for module versions, allowing the go command to download modules without needing direct access to version control systems [1]. pkg.go.dev This is a website that serves as a documentation hub and discovery service for Go packages. It indexes public Go modules and provides documentation, helping developers find and understand available packages. index.golang.org This service provides an index of new modules as they are published to the proxy. It allows services like pkg.go.dev to monitor the proxy for new content, enabling the discovery and indexing of new module versions in real-time. Protocol and Source Files The Go module proxy protocol defines how the go command interacts with proxies. When a module is requested, the proxy serves information and files based on the requested version. Specifically, when a module version is requested, the proxy can provide a.zip file (the source zip) containing the module's source code, which the go command downloads and caches locally [1]. These interactions occur over HTTP, and the go command automatically handles requests for module metadata and source files from the configured proxy [1].

In @.github/workflows/release.yml around lines 74 - 83, Update the “Warm
proxy.golang.org” workflow step to fetch the module archive through the proxy’s
.zip endpoint in addition to the required metadata, and remove the || true
fallbacks so any 404 or network failure causes the step to fail. Preserve the
existing module and GITHUB_REF_NAME-based URL construction.
