Types

type BundledGitEnvironmentConstructor 

type BundledGitEnvironmentConstructor struct {
	// Suffix is the version suffix used for this specific bundled Git environment. In case

	// of these bundled Git environments with different suffixes.
	Suffix string
	// FeatureFlags is the set of feature flags which must be enabled in order for the bundled
	// Git environment to be enabled. Note that _all_ feature flags must be set to `true` in the

	FeatureFlags []featureflag.FeatureFlag
}

BundledGitEnvironmentConstructor sets up an ExecutionEnvironment for a bundled Git installation. Bundled Git is a partial Git installation, where only a subset of Git binaries are installed into Gitaly's binary directory. The binaries must have a `gitaly-` prefix like e.g. `gitaly-git`. Bundled Git installations can be installed with Gitaly's Makefile via `make install WITH_BUNDLED_GIT=YesPlease`.

func (BundledGitEnvironmentConstructor) Construct 

func (c BundledGitEnvironmentConstructor) Construct(cfg config.Cfg) (_ ExecutionEnvironment, returnedErr error)

Construct sets up an ExecutionEnvironment for a bundled Git installation. Because bundled Git installations are not complete Git installations we need to set up a usable environment at runtime. This is done by creating a temporary directory into which we symlink the bundled binaries with their usual names as expected by Git. Furthermore, we configure the GIT_EXEC_PATH environment variable to point to that directory such that Git is able to locate its auxiliary binaries.

	Action string
	// Flags is the number of optional flags to pass before positional arguments, e.g.
	// `--oneline` or `--format=fuller`.
	Flags []Option
	// Args is the arguments that shall be passed after all flags. These arguments must not be
	// flags and thus cannot start with `-`. Note that it may be unsafe to use this field in the
	// case where arguments are directly user-controlled. In that case it is advisable to use
	// `PostSepArgs` instead.
	Args []string
	// PostSepArgs is the arguments that shall be passed as positional arguments after the `--`
	// separator. Git recognizes that separator as the point where it should stop expecting any
	// options and treat the remaining arguments as positionals. This should be used when
	// passing user-controlled input of arbitrary form like for example paths, which may start
	// with a `-`.
	PostSepArgs []string
}

func GetURLAndResolveConfig 

func GetURLAndResolveConfig(remoteURL string, resolvedAddress string) (string, []ConfigPair, error)

GetURLAndResolveConfig parses the given repository's URL and resolved address to generate the modified URL and configuration to avoid DNS rebinding.

In Git v2.37.0 we added the functionality for `http.curloptResolve` which like its curl counterpart when provided with a `HOST:PORT:ADDRESS` value, uses the IP Address provided directly for the given HOST:PORT combination for HTTP/HTTPS protocols, without requiring DNS resolution.

This functions currently does the following operations:

- Git Protocol: Replaces the hostname with the resolved IP address. - SSH Protocol: Replaces the hostname with the resolved IP address (supports both the regular syntax `ssh://[user@]server/project.git` and scp-like syntax `[user@]server:project.git`). - HTTP/HTTPS Protocol: Keeps the URL as is, but adds the `http.curloptResolve` flag.

SideNote: We cannot replace the hostname with IP in HTTPS protocol because the protocol demands the hostname to be present, as it is required for the SSL verification.

	// RefUpdateTypeFastForwardUpdate represents a 'fast forward update' fetch status line
	RefUpdateTypeFastForwardUpdate RefUpdateType = ' '
	// RefUpdateTypeForcedUpdate represents a 'forced update' fetch status line
	RefUpdateTypeForcedUpdate RefUpdateType = '+'
	// RefUpdateTypePruned represents a 'pruned' fetch status line
	RefUpdateTypePruned RefUpdateType = '-'
	// RefUpdateTypeTagUpdate represents a 'tag update' fetch status line
	RefUpdateTypeTagUpdate RefUpdateType = 't'
	// RefUpdateTypeFetched represents a 'fetched' fetch status line. This
	// indicates that a new reference has been created in the local repository
	RefUpdateTypeFetched RefUpdateType = '*'
	// RefUpdateTypeUpdateFailed represents an 'update failed' fetch status line
	RefUpdateTypeUpdateFailed RefUpdateType = '!'
	// RefUpdateTypeUnchanged represents an 'unchanged' fetch status line
	RefUpdateTypeUnchanged RefUpdateType = '='
)

func (RefUpdateType) Valid 

func (t RefUpdateType) Valid() bool

Valid checks whether the RefUpdateType is one of the seven valid types of update

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 git.Revision) (git.ObjectID, error)
	// HasBranches returns whether the repository has branches.
	HasBranches(ctx context.Context) (bool, error)
	// GetDefaultBranch returns the default branch of the repository.
	GetDefaultBranch(ctx context.Context) (git.ReferenceName, error)
	// HeadReference returns the reference that HEAD points to for the
	// repository.
	HeadReference(ctx context.Context) (git.ReferenceName, error)
}

Repository is the common interface of different repository implementations.

type RepositoryExecutor 

type RepositoryExecutor interface {
	storage.Repository
	Exec(ctx context.Context, cmd Command, opts ...CmdOpt) (*command.Command, error)
	ExecAndWait(ctx context.Context, cmd Command, opts ...CmdOpt) error
	GitVersion(ctx context.Context) (git.Version, error)
	ObjectHash(ctx context.Context) (git.ObjectHash, error)
	ReferenceBackend(ctx context.Context) (git.ReferenceBackend, error)
}

RepositoryExecutor is an interface which allows execution of Git commands in a specific repository.

type RequestWithGitProtocol

func NewShowRefDecoder 

func NewShowRefDecoder(r io.Reader) *ShowRefDecoder

NewShowRefDecoder returns a new ShowRefDecoder

func (*ShowRefDecoder) Decode 

func (d *ShowRefDecoder) Decode(ref *git.Reference) error

Decode reads and parses the next reference. Returns io.EOF when the end of the reader has been reached.

type StaticOption 

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

StaticOption are reusable trusted options

func (StaticOption) OptionArgs 

func (sa StaticOption) OptionArgs() ([]string, error)
