Types ¶
type FileMediaStore ¶
type FileMediaStore struct {
// contains filtered or unexported fields
}
FileMediaStore is a pure in-memory implementation of MediaStore. Files are expected to already exist on disk (e.g. in /tmp/picoclaw_media/).
func NewFileMediaStore ¶
func NewFileMediaStore() *FileMediaStore
NewFileMediaStore creates a new FileMediaStore without background cleanup.
func NewFileMediaStoreWithCleanup ¶
func NewFileMediaStoreWithCleanup(cfg MediaCleanerConfig) *FileMediaStore
NewFileMediaStoreWithCleanup creates a FileMediaStore with TTL-based background cleanup.
func (*FileMediaStore) CleanExpired ¶
func (s *FileMediaStore) CleanExpired() int
CleanExpired removes all entries older than MaxAge. Phase 1 (under lock): identify expired entries and remove from maps. Phase 2 (no lock): delete files from disk to minimize lock contention.
func (*FileMediaStore) ReleaseAll ¶
func (s *FileMediaStore) ReleaseAll(scope string) error
ReleaseAll removes all files under the given scope and cleans up mappings. Phase 1 (under lock): remove entries from maps. Phase 2 (no lock): delete files from disk.
func (*FileMediaStore) Resolve ¶
func (s *FileMediaStore) Resolve(ref string) (string, error)
Resolve returns the local path for the given ref.
func (*FileMediaStore) ResolveWithMeta ¶
func (s *FileMediaStore) ResolveWithMeta(ref string) (string, MediaMeta, error)
ResolveWithMeta returns the local path and metadata for the given ref.
func (*FileMediaStore) Start ¶
func (s *FileMediaStore) Start()
Start begins the background cleanup goroutine if cleanup is enabled. Safe to call multiple times; only the first call starts the goroutine.
func (*FileMediaStore) Stop ¶
func (s *FileMediaStore) Stop()
Stop terminates the background cleanup goroutine. Safe to call multiple times; only the first call closes the channel.
type MediaCleanerConfig ¶
MediaCleanerConfig configures the background TTL cleanup.
type MediaMeta ¶
type MediaMeta struct {
Filename string
ContentType string
Source string // "telegram", "discord", "tool:image-gen", etc.
}
MediaMeta holds metadata about a stored media file.
type MediaStore ¶
type MediaStore interface {
// Store registers an existing local file under the given scope.
// Returns a ref identifier (e.g. "media://<id>").
// Store does not move or copy the file; it only records the mapping.
Store(localPath string, meta MediaMeta, scope string) (ref string, err error)
// Resolve returns the local file path for a given ref.
Resolve(ref string) (localPath string, err error)
// ResolveWithMeta returns the local file path and metadata for a given ref.
ResolveWithMeta(ref string) (localPath string, meta MediaMeta, err error)
// ReleaseAll deletes all files registered under the given scope
// and removes the mapping entries. File-not-exist errors are ignored.
ReleaseAll(scope string) error
}
MediaStore manages the lifecycle of media files associated with processing scopes.
