Documentation

Overview

Package selfupdate updates the running draugr binary to a released version. Downloads are verified against the release's SHA-256 checksums (mandatory) and its keyless cosign signature (best-effort, when the cosign CLI is present) before the binary is replaced.

Functions

func CurrentVersion 

func CurrentVersion() string

CurrentVersion is the running binary's version (build stamp), without a leading "v".

func LatestVersion 

func LatestVersion(ctx context.Context, client *http.Client) (string, error)

LatestVersion resolves the latest published release version (no leading "v") via the github.com releases/latest redirect — deliberately not the api.github.com REST endpoint, which is rate-limited and has been flaky. Use a short timeout for interactive/offline paths.

Types

type Options 

type Options struct {
	Version string       // "" = latest
	Client  *http.Client // nil = default
}

Options configure an update.

type Result 

type Result struct {
	Previous          string // version before (may be "dev")
	Target            string // version updated (or would update) to
	NoChange          bool   // already on the target version
	SignatureVerified bool   // cosign signature verified (vs SHA-256-only)
	Note              string // provenance note (e.g. why cosign was skipped)
	Path              string // the binary that was replaced
}

Result describes a self-update outcome.

func Update 

func Update(ctx context.Context, opts Options) (Result, error)

Update replaces the running binary with the target release (latest if unset), after verifying its checksum and (best-effort) cosign signature. It is a no-op when already on the target version.
