| 18:11 | Fix OOM handling in sqlite3NestedParse(). (Leaf check-in: e6e9dd5c17 user: dan tags: nested-parse-oom) | |
| 16:41 | Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. (check-in: c13d563925 user: drh tags: trunk) | |

| 21:15 | Modifications to the zonefile module to make it easier to add a cache of uncompressed frame content. (check-in: d9d5cc62f1 user: dan tags: zonefile) | |
| 16:36 | Have zonefile store encryption keys in a hash-table instead of a linked list. Add extra tests for key management. (check-in: 3a63ea6525 user: dan tags: zonefile) | |
| 10:43 | In zonefile, change the "file TEXT" column back to "fileid INTEGER". The fileid can be used as a key with the associated zonefile_files table, which contains more information than just the filename. (check-in: 38d23888cf user: dan tags: zonefile) | |
| 01:48 | Remove an unreachable branch in the walIndexPage() logic. (check-in: 4e61a9731f user: drh tags: trunk) | |
| 01:05 | Small performance improvement in sqltie3WalFindFrame(). (check-in: 52013cad0e user: drh tags: trunk) | |
| 00:48 | Remove an unnecessary memset(). (check-in: e7b7f5884a user: drh tags: trunk) | |

| 21:24 | In sqlite3VdbeHalt(), return as soon as possible if Vdbe.magic!=VDBE_MAGIC_RUN. This makes sqlite3_reset() slightly faster in some cases. (check-in: 80adc0cb4e user: dan tags: trunk) | |
| 17:52 | Fix an FTS5 problem that could cause a crash when certain queries were interrupted using sqlite3_interrupt(). (check-in: e400909f31 user: dan tags: trunk) | |
| 15:27 | Very small enhancement to dispatch speed for SQL functions. (check-in: 3c3228ed16 user: drh tags: trunk) | |
| 14:04 | The VDBE cycle counts for the sqlite3_progress_handler() callback are now cumulative. Leftovers from the previous statement are applied to the next statement. (Leaf check-in: 7a62fc6abc user: drh tags: cumulative-progress-count) | |
| 13:29 | Proof of concept for a "PRAGMA vdbe_cycle_limit=N" command. When N>0, invoke sqlite3_interrupt() whenever any byte code program uses more than N virtual machine cycles. (Leaf check-in: 9626b41e6e user: drh tags: vdbe_cycle_limit) | |
