Constants

❖
const (
    // LargeFileThreshold defines a number of bytes to use FILE_META instead of FILE.
    LargeFileThreshold = 2 * 1024 * 1024

    // FileChunkSize defines a size of each FILE_CHUNK content.
    FileChunkSize = 2 * 1024 * 1024
)
❖
const (
    // DefaultMaxMsgSize is max message size for file service.
    // file service will handle 2MB chunk * 5 chunks in a request.
    // grpc's default is 4MB.
    DefaultMaxMsgSize = 12 * 1024 * 1024
)

func FromLocal Uses

❖
func FromLocal(ctx context.Context, fc filepb.FileServiceClient, fname string, blob *gomapb.FileBlob) (os.FileInfo, error)

FromLocal reads fname and fills in blob, and stores it in FileServiceClient.

func FromReader Uses

❖
func FromReader(ctx context.Context, fc filepb.FileServiceClient, r io.Reader, blob *gomapb.FileBlob) error

FromReader reads contents from r and fills in blob, and stores it in FileServiceClient if fc != nil. content size must be blob's FileSize.

func IsValid Uses

❖
func IsValid(blob *gomapb.FileBlob) bool

IsValid checks blob is valid FileBlob.

func Key Uses

❖
func Key(blob *gomapb.FileBlob) (string, error)

Key returns hash key for blob.

func ToLocal Uses

❖
func ToLocal(ctx context.Context, fc filepb.FileServiceClient, blob *gomapb.FileBlob, fname string) error

ToLocal writes FileBlob contents in fname. If FileBlob is FILE_META, it will fetch FILE_CHUNK using FileServiceClient.

type BlobSpec Uses

❖
type BlobSpec struct {
    HashKey      string
    Blob         *gomapb.FileBlob
    IsExecutable bool
}

BlobSpec represents a file by HashKey and/or Blob.

func (*BlobSpec) Init Uses

❖
func (b *BlobSpec) Init(ctx context.Context, client filepb.FileServiceClient) error

Init initializes BlobSpec from HashKey or Blob. Either HashKey or Blob must be set before initialization.

type Disk Uses

❖
type Disk struct {
    Client filepb.FileServiceClient
}

Disk provides convenient methods to convert between local file and FileBlob in goma file service.

func (Disk) FromLocal Uses

❖
func (d Disk) FromLocal(ctx context.Context, fname string, spec *BlobSpec) error

FromLocal fills spec from fname.

func (Disk) ToLocal Uses

❖
func (d Disk) ToLocal(ctx context.Context, spec *BlobSpec, fname string) error

ToLocal creates file named fname from spec.

type LocalCache Uses

❖
type LocalCache struct {
    // Client is goma file service client.
    // If it is nil, it only uses local disk cache.
    Client filepb.FileServiceClient

    // Dir is a directory for local disk cache.
    Dir string
}

LocalCache is a goma file service with local disk cache.

func (LocalCache) LookupFile Uses

❖
func (c LocalCache) LookupFile(ctx context.Context, req *gomapb.LookupFileReq, opts ...grpc.CallOption) (*gomapb.LookupFileResp, error)

LookupFile looks up FileBlob for requested hash keys. It it is found in local disk cache, it will be used. Otherwise and c.Client is not nil, ask c.Client.

func (LocalCache) StoreFile Uses

❖
func (c LocalCache) StoreFile(ctx context.Context, req *gomapb.StoreFileReq, opts ...grpc.CallOption) (*gomapb.StoreFileResp, error)

StoreFile stores FileBlob in local disk, and c.Client if c.Client is not nil.

type Service Uses

❖
type Service struct {
    // Cache is a fileblob storage.
    Cache cachepb.CacheServiceClient
}

Service represents goma file service.

func (*Service) LookupFile Uses

❖
func (s *Service) LookupFile(ctx context.Context, req *gomapb.LookupFileReq) (*gomapb.LookupFileResp, error)

LookupFile looks up FileBlob.

func (*Service) StoreFile Uses

❖
func (s *Service) StoreFile(ctx context.Context, req *gomapb.StoreFileReq) (*gomapb.StoreFileResp, error)

StoreFile stores FileBlob.
