| 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 | |
| 13:59 | Fix an undersized buffer in the SHA1 implementation. Closed-Leaf check-in: fb276815 user: drh tags: dbhash | |
| 13:49 | Fix the dbhash utility so that it ignores the root page number when hashing the sqlite_master table. Add new command-line options. Add the ability to hash multiple databases with a single command. check-in: 44f157e0 user: drh tags: dbhash | |
