Functions

func AlternateObjectDirectories

func AlternateObjectDirectories(ctx context.Context, storageRoot, repoPath string) ([]string, error)

AlternateObjectDirectories reads the alternates file of the repository and returns absolute paths to its alternate object directories, if any. The returned directories are verified to exist and that they are within the storage root. The alternate directories are returned recursively, not only the immediate alternates.

func BuildSSHInvocation

func BuildSSHInvocation(ctx context.Context, sshKey, knownHosts string) (string, func(), error)

BuildSSHInvocation builds a command line to invoke SSH with the provided key and known hosts. Both are optional.

func CheckRefFormat

func CheckRefFormat(ctx context.Context, gitCmdFactory CommandFactory, refName string) (bool, error)

CheckRefFormat checks whether a fully-qualified refname is well well-formed using git-check-ref-format

func IsInvalidArgErr

func IsInvalidArgErr(err error) bool

IsInvalidArgErr relays if the error is due to an argument validation failure

func IsLFSPointer

func IsLFSPointer(b []byte) bool

IsLFSPointer checks to see if a blob is an LFS pointer. TODO: this is incomplete as it does not recognize pre-release version of LFS blobs with the "https://hawser.github.com/spec/v1" version. For compatibility with the Ruby RPC, we leave this as-is for now though.

func ObjectDirectories

func ObjectDirectories(ctx context.Context, storageRoot, repoPath string) ([]string, error)

ObjectDirectories looks for Git object directories, including alternates specified in objects/info/alternates.

CAVEAT Git supports quoted strings in here, but we do not. We should never need those on a Gitaly server.

func ValidateObjectID

func ValidateObjectID(id string) error

ValidateObjectID checks if id is a syntactically correct object ID. Abbreviated object IDs are not deemed to be valid. Returns an ErrInvalidObjectID if the id is not valid.

func ValidateRevision

func ValidateRevision(revision []byte) error

ValidateRevision checks if a revision looks valid

func ValidateRevisionAllowEmpty

func ValidateRevisionAllowEmpty(revision []byte) error

ValidateRevisionAllowEmpty checks if a revision looks valid, but allows empty strings

func WarnIfTooManyBitmaps

func WarnIfTooManyBitmaps(ctx context.Context, locator storage.Locator, storageName, repoPath string)

WarnIfTooManyBitmaps checks for too many (more than one) bitmaps in repoPath, and if it finds any, it logs a warning. This is to help us investigate https://gitlab.com/gitlab-org/gitaly/issues/1728.

type Repository

type Repository interface {
	// ResolveRevision tries to resolve the given revision to its object
	// ID. This uses the typical DWIM mechanism of git, see gitrevisions(1)
	// for accepted syntax. This will not verify whether the object ID
	// exists. To do so, you can peel the reference to a given object type,
	// e.g. by passing `refs/heads/master^{commit}`.
	ResolveRevision(ctx context.Context, revision Revision) (ObjectID, error)
	// HasBranches returns whether the repository has branches.
	HasBranches(ctx context.Context) (bool, error)
}

Repository is the common interface of different repository implementations.

type SubCmd

type SubCmd struct {
	Name        string   // e.g. "log", or "cat-file", or "worktree"
	Flags       []Option // optional flags before the positional args
	Args        []string // positional args after all flags
	PostSepArgs []string // post separator (i.e. "--") positional args
}

SubCmd represents a specific git command

func (SubCmd) CommandArgs

func (sc SubCmd) CommandArgs() ([]string, error)

CommandArgs checks all arguments in the sub command and validates them

func (SubCmd) Subcommand

func (sc SubCmd) Subcommand() string

Subcommand returns the subcommand name

type SubSubCmd

type SubSubCmd struct {
	// Name is the name of the subcommand, e.g. "remote" in `git remote set-url`
	Name string
	// Action is the action of the subcommand, e.g. "set-url" in `git remote set-url`
	Action string

	// Flags are optional flags before the positional args
	Flags []Option
	// Args are positional arguments after all flags
	Args []string
	// PostSepArgs are positional args after the "--" separator
	PostSepArgs []string
}

SubSubCmd is a positional argument that appears in the list of options for a subcommand.

func (SubSubCmd) CommandArgs

func (sc SubSubCmd) CommandArgs() ([]string, error)

CommandArgs checks all arguments in the SubSubCommand and validates them, returning the array of all arguments required to execute it.

func (SubSubCmd) Subcommand

func (sc SubSubCmd) Subcommand() string

Subcommand returns the name of the given git command which this SubSubCmd executes. E.g. for `git remote add`, it would return "remote".

type ValueFlag

type ValueFlag struct {
	Name  string
	Value string
}

ValueFlag is an optional command line argument that is comprised of pair of tokens (e.g. "-n 50")

func (ValueFlag) GlobalArgs

func (vf ValueFlag) GlobalArgs() ([]string, error)

GlobalArgs returns the arguments for the given value flag, which should typically be two arguments: the flag and its value. It returns an error if the value flag is not sanitary.

func (ValueFlag) OptionArgs

func (vf ValueFlag) OptionArgs() ([]string, error)

OptionArgs returns an error if the flag is not sanitary

type Version

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

Version represents the version of git itself.

func CurrentVersion

func CurrentVersion(ctx context.Context, gitCmdFactory CommandFactory) (Version, error)

CurrentVersion returns the used git version.

func (Version) IsSupported

func (v Version) IsSupported() bool

IsSupported checks if a version string corresponds to a Git version supported by Gitaly.

func (Version) LessThan

func (v Version) LessThan(other Version) bool

LessThan determines whether the version is older than another version.

func (Version) String

func (v Version) String() string

String returns the string representation of the version.

func (Version) SupportsObjectTypeFilter added in v14.1.0

func (v Version) SupportsObjectTypeFilter() bool
