Functions

func MappingsFromConfig added in v2.15.0 

func MappingsFromConfig(cfg *config.Instance) []database.Mapping

MappingsFromConfig converts the file-based mappings loaded into config into the database.Mapping shape used for matching and API responses. The returned mappings are always enabled and carry no database ID, since they originate from the mappings folder rather than UserDB.

func NormalizeID 

func NormalizeID(uid string) string

func (*UserDB) GetMediaHistoryIdentityBackfillBatch added in v2.16.1 

func (db *UserDB) GetMediaHistoryIdentityBackfillBatch(
	afterDBID int64, policyVersion int, limit int,
) ([]database.MediaHistoryEntry, error)

GetMediaHistoryIdentityBackfillBatch returns legacy history rows whose scanner identity is absent or older than policyVersion. Future-policy rows are never selected for downgrade.

func (*UserDB) GetMediaHistorySyncBatch added in v2.16.0 

func (db *UserDB) GetMediaHistorySyncBatch(
	after time.Time, afterDBID int64, limit int,
) ([]database.MediaHistoryEntry, error)

GetMediaHistorySyncBatch returns unsynced rows after the local (after, afterDBID) cursor in (UpdatedAt, DBID) order. Mutations clear SyncedAt, so acknowledged rows do not repeat and unreliable-clock rows remain eligible regardless of the server's timestamp watermark. Rows without a session UUID are excluded; startup backfills legacy rows first.

func (*UserDB) GetMediaHistoryTop added in v2.10.0 

func (db *UserDB) GetMediaHistoryTop(
	systemIDs []string, since *time.Time, limit int,
) ([]database.MediaHistoryTopEntry, error)

func (db *UserDB) GetZapLinkCache(url string) (string, error)

func (*UserDB) GetZapLinkHost 

func (db *UserDB) GetZapLinkHost(host string) (found, zapScript bool, err error)

func (*UserDB) HealTimestamps added in v2.7.0 

func (db *UserDB) HealTimestamps(bootUUID string, trueBootTime time.Time) (int64, error)

HealTimestamps corrects timestamps for records created with unreliable clocks (MiSTer boot without NTP). When NTP syncs, this reconstructs correct timestamps using: TrueStartTime = TrueBootTime + MonotonicStart

func (*UserDB) IntegrityReport added in v2.15.0 

func (db *UserDB) IntegrityReport() []string

func (*UserDB) IsMarkedCorrupt added in v2.15.0 

func (db *UserDB) IsMarkedCorrupt() bool

func (*UserDB) ListBackups added in v2.15.0 

func (db *UserDB) ListBackups() ([]database.BackupInfo, error)

func (db *UserDB) ListClients() ([]database.Client, error)

func (*UserDB) ListMediaUserData added in v2.15.0 

func (db *UserDB) ListMediaUserData() ([]database.MediaUserData, error)

ListMediaUserData returns every user-data row, used by the reindex re-apply step to re-materialize the media.db projection.

func (*UserDB) ListProfiles added in v2.16.0 

func (db *UserDB) ListProfiles() ([]database.Profile, error)

func (*UserDB) MarkCorrupt added in v2.15.0

func (db *UserDB) MarkMediaHistorySynced(refs []database.MediaHistorySyncRef, syncedAt time.Time) error

MarkMediaHistorySynced stamps SyncedAt only when each row still matches the uploaded version. Concurrent mutations advance UpdatedAt and remain unsynced.

func (*UserDB) MigrateUp 

func (db *UserDB) MigrateUp() error

func (*UserDB) NoteCorruption added in v2.15.0 

func (db *UserDB) NoteCorruption(err error) bool

func (*UserDB) Open 

func (db *UserDB) Open() error

func (*UserDB) PruneExpiredZapLinkHosts added in v2.8.0 

func (db *UserDB) PruneExpiredZapLinkHosts(olderThan time.Duration) (int64, error)

func (*UserDB) RecoverFromCorruption added in v2.15.0 

func (db *UserDB) RecoverFromCorruption() (database.RestoreInfo, error)

func (*UserDB) ReplaceAllClients added in v2.16.0 

func (db *UserDB) ReplaceAllClients(clients []database.Client) error

ReplaceAllClients atomically replaces every paired client row. Device backup restore uses this to carry the destination's paired clients across a restored user database, since portable snapshots are created without client rows.

func (*UserDB) ResetMediaHistorySyncAfter added in v2.16.0 

func (db *UserDB) ResetMediaHistorySyncAfter(watermark *time.Time) error

ResetMediaHistorySyncAfter clears local acknowledgements newer than the server watermark so restored or reset server state is uploaded again. A nil watermark means the server has no sessions and resets every local row.

func (*UserDB) RestoreBackup added in v2.15.0 

func (db *UserDB) RestoreBackup(name string) (database.RestoreInfo, error)

func (*UserDB) SetDeviceState added in v2.16.0 

func (db *UserDB) SetDeviceState(key, value string) error

func (*UserDB) SetMediaUserFavorite added in v2.15.0 

func (db *UserDB) SetMediaUserFavorite(systemID, path string, favorite bool) error

SetMediaUserFavorite records (or clears) the favourite intent for a media path without disturbing any launcher override on the same row. The write is a column-scoped upsert plus a conditional delete, run in one transaction so two concurrent edits to the same path (e.g. a favourite toggle and a launcher override) cannot read-modify-write over each other.

func (*UserDB) SetMediaUserLauncherOverride added in v2.15.0 

func (db *UserDB) SetMediaUserLauncherOverride(systemID, path, launcherID string) error

SetMediaUserLauncherOverride records (or clears, when launcherID is empty) the launcher-override intent for a media path without disturbing the favourite flag on the same row. See SetMediaUserFavorite for the concurrency guarantee.

func (*UserDB) SetMediaUserSnapshot added in v2.16.0 

func (db *UserDB) SetMediaUserSnapshot(systemID, path, mediaName string, tags []string) error

SetMediaUserSnapshot records a successfully resolved scanner identity snapshot on an existing user-data row. It never inserts: a snapshot without user intent (favourite/override) is meaningless. Empty tags are significant and replace stale tags; callers must skip this method when lookup fails.

func (*UserDB) SetSQLForTesting 

func (db *UserDB) SetSQLForTesting(ctx context.Context, sqlDB *sql.DB, platform platforms.Platform) error

SetSQLForTesting allows injection of a sql.DB instance for testing purposes. This method should only be used in tests to set up in-memory databases.

func (*UserDB) SumMediaPlayTimeForDay added in v2.15.0 

func (db *UserDB) SumMediaPlayTimeForDay(dayStart time.Time) (int64, error)

SumMediaPlayTimeForDay returns the total seconds of completed play-time that overlaps with the day starting at dayStart. Sessions that span midnight are pro-rated: only the portion after dayStart is counted. The currently-active session (EndTime IS NULL) is excluded; callers add it separately.

func (*UserDB) SumMediaPlayTimeForDayByProfile added in v2.16.0 

func (db *UserDB) SumMediaPlayTimeForDayByProfile(dayStart time.Time, profileID string) (int64, error)

SumMediaPlayTimeForDayByProfile is SumMediaPlayTimeForDay scoped to history attributed to a single profile. History with no profile (the shared profile) is counted by SumMediaPlayTimeForDay, which sums all rows: shared limits are device-level, so deactivating a profile must not grant a fresh daily allowance.

func (*UserDB) Truncate 

func (db *UserDB) Truncate() error

func (*UserDB) UnsafeGetSQLDb 

func (db *UserDB) UnsafeGetSQLDb() *sql.DB

func (*UserDB) UpdateClientLastSeen added in v2.11.0 

func (db *UserDB) UpdateClientLastSeen(authToken string, lastSeenAt int64) error

func (*UserDB) UpdateMapping 

func (db *UserDB) UpdateMapping(id int64, m *database.Mapping) error

func (*UserDB) UpdateMediaHistoryIdentity added in v2.16.0 

func (db *UserDB) UpdateMediaHistoryIdentity(dbid int64, identity *database.MediaIdentity) (bool, error)

UpdateMediaHistoryIdentity stores a complete scanner identity snapshot and reports whether this policy version changed the history row.

func (*UserDB) UpdateMediaHistoryTime added in v2.7.0 

func (db *UserDB) UpdateMediaHistoryTime(dbid int64, playTime int) error

UpdateMediaHistoryTime updates only the PlayTime for currently playing media.

func (*UserDB) UpdateProfile added in v2.16.0 

func (db *UserDB) UpdateProfile(p *database.Profile) error

func (*UserDB) UpdateZapLinkCache 

func (db *UserDB) UpdateZapLinkCache(url, zapscript string) error

func (*UserDB) UpdateZapLinkHost 

func (db *UserDB) UpdateZapLinkHost(host string, zapscript int) error

func (*UserDB) UpsertMediaUserData added in v2.15.0 

func (db *UserDB) UpsertMediaUserData(data *database.MediaUserData) error

UpsertMediaUserData inserts or updates the user-data row for (SystemID, Path). CreatedAt is set on insert only; UpdatedAt is set on every write. A row with no favourite and no launcher override carries no user intent, so it is deleted rather than persisted (keeping ListMediaUserData and the backfill guard honest).

func (*UserDB) Vacuum 

func (db *UserDB) Vacuum() error
