14:04
Add the "dbhash.exe" utility program that computes a SHA1 hash over the invariant content of an SQLite database file. Free space in the file, the page size, auto_vacuum status, text encoding, and so forth do not change the hash. Only the content matters. (check-in: f48a4ad3 user: drh tags: trunk)
