Types ¶

type ChecksumDB ¶

type ChecksumDB struct {
	// contains filtered or unexported fields
}

ChecksumDB keeps file checksums and tool versions.

func MustLoadChecksums ¶

func MustLoadChecksums(file string) *ChecksumDB

MustLoadChecksums loads a file containing checksums.

func ParseChecksums ¶

func ParseChecksums(input []byte) (*ChecksumDB, error)

ParseChecksums parses a checksum database.

func (*ChecksumDB) DownloadAndVerifyAll ¶

func (db *ChecksumDB) DownloadAndVerifyAll()

DownloadAndVerifyAll downloads all files and checks that they match the checksum given in the database. This task can be used to sanity-check new checksums.

func (*ChecksumDB) DownloadFile ¶

func (db *ChecksumDB) DownloadFile(url, dstPath string) error

DownloadFile downloads a file and verifies its checksum.

func (*ChecksumDB) DownloadFileFromKnownURL ¶

func (db *ChecksumDB) DownloadFileFromKnownURL(dstPath string) error

DownloadFileFromKnownURL downloads a file from the URL defined in the checksum database.

func (*ChecksumDB) Files ¶

func (db *ChecksumDB) Files() iter.Seq[string]

Files returns an iterator over all file names.

func (*ChecksumDB) FindURL ¶

func (db *ChecksumDB) FindURL(basename string) (string, error)

FindURL gets the URL for a file.

func (*ChecksumDB) FindVersion ¶

func (db *ChecksumDB) FindVersion(tool string) (string, error)

FindVersion returns the current known version of a tool, if it is defined in the file.
