| 01:00 | Move the sqlite3LocateCollSeq(), sqlite3FindCollSeq(), and sqlite3GetCollSeq() routines so that they are all beside one another in the callback.c source file. No logic changes. check-in: 9ff80a9b user: drh tags: trunk | |
| 00:03 | When flipping ("commuting") a comparison operator, set the new EP_Commuted bit rather than adding extra EP_Collate bits, to single later processing that the order of precedence for COLLATE operators is inverted.

| 19:53 | Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis.
