Overview ¶
Package dblock exposes the SQLite-compatible byte-range lock used by Replica.applyLTXFile. External callers that mirror the LTX apply pipeline (e.g. shard-layer standby readers) take the same lock so they interlock with SQLite's own locking and with each other.
The pending-byte + shared-region ranges are SQLite-internal addresses (sqlitePendingByte=0x40000000); locking those bytes blocks any SQLite reader/writer process that opens the same file, matching the granularity used by replicate's internal applyLTXFile.
