var DefaultSSHKeyExchangeAlgorithms = SupportedSSHKeyExchangeAlgorithms

List of default key exchange algorithms to use. We use those that are available by default, we can become more opinionated later on (when we support configuration of algorithms to use).

Functions

func GetRepoHTTPClient 

func GetRepoHTTPClient(repoURL string, insecure bool, creds Creds, proxyURL string) *http.Client

Returns a HTTP client object suitable for go-git to use using the following pattern:

  • If insecure is true, always returns a client with certificate verification turned off.
  • If one or more custom certificates are stored for the repository, returns a client with those certificates in the list of root CAs used to verify the server's certificate.
  • Otherwise (and on non-fatal errors), a default HTTP client is returned.

func IsCommitSHA 

func IsCommitSHA(sha string) bool

IsCommitSHA returns whether or not a string is a 40 character SHA-1

func IsHTTPSURL 

func IsHTTPSURL(url string) bool

IsHTTPSURL returns true if supplied URL is HTTPS URL

func IsHTTPURL added in v2.1.0 

func IsHTTPURL(url string) bool

IsHTTPURL returns true if supplied URL is HTTP URL

func IsSSHURL 

func IsSSHURL(url string) (bool, string)

IsSSHURL returns true if supplied URL is SSH URL

func IsTruncatedCommitSHA 

func IsTruncatedCommitSHA(sha string) bool

IsTruncatedCommitSHA returns whether or not a string is a truncated SHA-1

func NormalizeGitURL 

func NormalizeGitURL(repo string) string

NormalizeGitURL normalizes a git URL for purposes of comparison, as well as preventing redundant local clones (by normalizing various forms of a URL to a consistent location). Prefer using SameURL() over this function when possible. This algorithm may change over time and should not be considered stable from release to release

func SameURL 

func SameURL(leftRepo, rightRepo string) bool

SameURL returns whether or not the two repository URLs are equivalent in location

func TestRepo 

func TestRepo(repo string, creds Creds, insecure bool, enableLfs bool, proxy string) error

TestRepo tests if a repo exists and is accessible with the given credentials
