Types ¶
type FileMetaDatabase ¶
type FileMetaDatabase interface {
Connect() error
WriteFile(sf *StoredFile) error
GetFile(id string) (*StoredFile, error)
GetAllFiles() ([]*StoredFile, error)
GetAllExpired() ([]*StoredFile, error)
DeleteFile(id string) error
}
FileMetaDatabase is for storing additional meta information on each file, e.g. the time a file has been uploaded or more imporantly when the file should be expired.
On startup, we check for every entry that is expired and delete it accordingly.
type FileStorage ¶
type FileStorage struct {
// contains filtered or unexported fields
}
FileStorage is the abstraction layer for storing uploaded files. It consists of a file system where the physical files are written to and a seperate database, where it stores metadata for each file.
func NewFileStorage ¶
func NewFileStorage() *FileStorage
func (*FileStorage) Cleanup ¶
func (fs *FileStorage) Cleanup() error
Cleanup uses the meta database to check for all files that have expired and deletes them accordingly.
func (*FileStorage) StoreFile ¶
func (fs *FileStorage) StoreFile(rff *request.RequestFormFile, expiration int64) (*StoredFile, error)
type FileSystem ¶
type FileSystem interface {
// CreateFile writes the content of given reader to a file
// with given name.
// Always returns if the file was partly written to disk.
CreateFile(r io.Reader, name string) (bool, error)
DeleteFile(id string) error
GetFile(id string) (*os.File, error)
Exists(id string) (bool, error)
}
type LocalFileSystem ¶
type LocalFileSystem struct {
FolderPath string
}
func NewLocalFileStorage ¶
func NewLocalFileStorage(path string) *LocalFileSystem
func (LocalFileSystem) CreateFile ¶
func (LocalFileSystem) DeleteFile ¶
func (l LocalFileSystem) DeleteFile(id string) error
type SqliteFileMetaDatabase ¶
func NewSqliteFileMetaDatabase ¶
func NewSqliteFileMetaDatabase(folderPath string) *SqliteFileMetaDatabase
func (*SqliteFileMetaDatabase) Connect ¶
func (s *SqliteFileMetaDatabase) Connect() error
func (*SqliteFileMetaDatabase) DeleteFile ¶
func (s *SqliteFileMetaDatabase) DeleteFile(id string) error
func (*SqliteFileMetaDatabase) GetAllExpired ¶
func (s *SqliteFileMetaDatabase) GetAllExpired() ([]*StoredFile, error)
func (*SqliteFileMetaDatabase) GetAllFiles ¶
func (s *SqliteFileMetaDatabase) GetAllFiles() ([]*StoredFile, error)
func (*SqliteFileMetaDatabase) GetFile ¶
func (s *SqliteFileMetaDatabase) GetFile(id string) (*StoredFile, error)
func (*SqliteFileMetaDatabase) WriteFile ¶
func (s *SqliteFileMetaDatabase) WriteFile(sf *StoredFile) error
