Functions

func FormatTag

func FormatTag(
	objectID git.ObjectID,
	objectType string,
	tagName, tagBody []byte,
	committer *gitalypb.User,
	committerDate time.Time,
) (string, error)

FormatTag is used by WriteTag (or for testing) to make the tag signature to feed to git-mktag, i.e. the plain-text mktag format. This does not create an object, just crafts input for "git mktag" to consume.

We are not being paranoid about exhaustive input validation here because we're just about to run git's own "fsck" check on this.

However, if someone injected parameters with extra newlines they could cause subsequent values to be ignore via a crafted message. This someone could also locally craft a tag locally and "git push" it. But allowing e.g. someone to provide their own timestamp here would at best be annoying, and at worst run up against some other assumption (e.g. that some hook check isn't as strict on locally generated data).

New creates a new Repo from its protobuf representation.

func NewTestRepo

func NewTestRepo(t testing.TB, cfg config.Cfg, repo repository.GitRepo, factoryOpts ...git.ExecCommandFactoryOption) *Repo

func (*Repo) GuessHead added in v14.6.0

func (repo *Repo) GuessHead(ctx context.Context, head git.Reference) (git.ReferenceName, error)

GuessHead tries to guess what branch HEAD would be pointed at. If no reference is found git.ErrReferenceNotFound is returned.

This function should be roughly equivalent to the corresponding function in git: https://github.com/git/git/blob/2a97289ad8b103625d3a1a12f66c27f50df822ce/remote.c#L2198

func (*Repo) HasRevision

func (repo *Repo) HasRevision(ctx context.Context, revision git.Revision) (bool, error)

func (*Repo) ObjectDirectoryPath added in v14.8.0

func (repo *Repo) ObjectDirectoryPath() (string, error)

ObjectDirectoryPath returns the full path of the object directory. The errors returned are gRPC errors with relevant error codes and should be passed back to gRPC without further decoration.

func (*Repo) Path

func (repo *Repo) Path() (string, error)

Path returns the on-disk path of the repository.

func (*Repo) Push

func (repo *Repo) Push(ctx context.Context, remote string, refspecs []string, options PushOptions) error

func (*Repo) ReadCommit

func (repo *Repo) ReadCommit(ctx context.Context, revision git.Revision, opts ...ReadCommitOpt) (*gitalypb.GitCommit, error)

func (*Repo) ReadObject

func (repo *Repo) ReadObject(ctx context.Context, oid git.ObjectID) ([]byte, error)

ReadObject reads an object from the repository's object database. InvalidObjectError is returned if the oid does not refer to a valid object.

func (*Repo) ResolveRevision

func (repo *Repo) ResolveRevision(ctx context.Context, revision git.Revision) (git.ObjectID, error)

ResolveRevision resolves the given revision to its object ID. This will not verify whether the target object exists. To do so, you can peel the reference to a given object type, e.g. by passing `refs/heads/master^{commit}`. Returns an ErrReferenceNotFound error in case the revision does not exist.

func (*Repo) SetConfig added in v14.4.0

func (repo *Repo) SetConfig(ctx context.Context, key, value string, txManager transaction.Manager) (returnedErr error)

SetConfig will set a configuration value. Any preexisting values will be overwritten with the new value. The change will use transactional semantics.

func (*Repo) SetDefaultBranch added in v14.7.0

func (repo *Repo) SetDefaultBranch(ctx context.Context, txManager transaction.Manager, reference git.ReferenceName) error

SetDefaultBranch sets the repository's HEAD to point to the given reference. It will not verify the reference actually exists.

func (*Repo) UnsetMatchingConfig added in v14.4.0

func (repo *Repo) UnsetMatchingConfig(
	ctx context.Context,
	regex string,
	txManager transaction.Manager,
) (returnedErr error)

UnsetMatchingConfig removes all config entries whose key match the given regular expression. If no matching keys are found, then this function returns an `git.ErrNotFound` error. The change will use transactional semantics.

func (*Repo) UpdateRef

func (repo *Repo) UpdateRef(ctx context.Context, reference git.ReferenceName, newValue, oldValue git.ObjectID) error

UpdateRef updates reference from oldValue to newValue. If oldValue is a non-empty string, the update will fail it the reference is not currently at that revision. If newValue is the ZeroOID, the reference will be deleted. If oldValue is the ZeroOID, the reference will created.

func (*Repo) WriteBlob

func (repo *Repo) WriteBlob(ctx context.Context, path string, content io.Reader) (git.ObjectID, error)

WriteBlob writes a blob to the repository's object database and returns its object ID. Path is used by git to decide which filters to run on the content.

func (*Repo) WriteTag

func (repo *Repo) WriteTag(
	ctx context.Context,
	objectID git.ObjectID,
	objectType string,
	tagName, tagBody []byte,
	committer *gitalypb.User,
	committerDate time.Time,
) (git.ObjectID, error)

WriteTag writes a tag to the repository's object database with git-mktag and returns its object ID.

It's important that this be git-mktag and not git-hash-object due to its fsck sanity checking semantics.
