Functions

func Unlink

func Unlink(ctx context.Context, repo repository.GitRepo) error

Unlink removes the alternates file, so Git won't look there anymore

Types

type ObjectPool

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

ObjectPool are a way to dedup objects between repositories, where the objects live in a pool in a distinct repository which is used as an alternate object store for other repositories.

func NewObjectPool

func NewObjectPool(storageName, relativePath string) (pool *ObjectPool, err error)

NewObjectPool will initialize the object with the required data on the storage shard. If the shard cannot be found, this function returns an error

func (*ObjectPool) Create

func (o *ObjectPool) Create(ctx context.Context, repo *gitalypb.Repository) (err error)

Create will create a pool for a repository and pull the required data to this pool. `repo` that is passed also joins the repository.

func (*ObjectPool) Exists

func (o *ObjectPool) Exists() bool

Exists will return true if the pool path exists and is a directory

func (*ObjectPool) FullPath

func (o *ObjectPool) FullPath() string

FullPath on disk, depending on the storage path, and the pools relative path

func (*ObjectPool) GetGitAlternateObjectDirectories

func (o *ObjectPool) GetGitAlternateObjectDirectories() []string

GetGitAlternateObjectDirectories for object pools are empty, given pools are never a member of another pool, nor do they share Alternate objects with other repositories which the pool doesn't contain itself

func (*ObjectPool) GetGitObjectDirectory

func (o *ObjectPool) GetGitObjectDirectory() string

GetGitObjectDirectory satisfies the repository.GitRepo interface, but is not used for ObjectPools

func (*ObjectPool) GetRelativePath

func (o *ObjectPool) GetRelativePath() string

GetRelativePath will create the relative path to the ObjectPool from the storage path.

func (*ObjectPool) GetStorageName

func (o *ObjectPool) GetStorageName() string

GetStorageName exposes the shard name, to satisfy the repository.GitRepo interface

func (*ObjectPool) IsValid

func (o *ObjectPool) IsValid() bool

IsValid checks if a repository exists, and if its valid.

func (*ObjectPool) Link

func (o *ObjectPool) Link(ctx context.Context, repo repository.GitRepo) error

Link will write the relative path to the object pool from the repository that is to join the pool. This does not trigger deduplication, which is the responsibility of the caller.

func (*ObjectPool) Remove

func (o *ObjectPool) Remove(ctx context.Context) (err error)

Remove will remove the pool, and all its contents without preparing and/or updating the repositories depending on this object pool Subdirectories will remain to exist, and will never be cleaned up, even when these are empty.

func (*ObjectPool) ToProto

func (o *ObjectPool) ToProto() *gitalypb.ObjectPool

ToProto returns a new struct that is the protobuf definition of the ObjectPool
