| 19:18 | Refactor the sqlite3BtreeKey() and sqlite3BtreeData() internal interfaces into sqlite3BtreePayload() and sqlite3BtreePayloadChecked(), respectively. This is a continuation of the optimization started by check-in [2d831074cf]. The result is a slightly smaller and faster binary. (check-in: 49ebc219fa user: drh tags: trunk) | |
| 17:03 | Small performance increase and size reduction in the OP_Column opcode. (check-in: a9498407e6 user: drh tags: trunk) | |

| 20:31 | Fix OOM error reporting in the json1_group_object() SQL function. Remove an unreachable branch from the JSON1 logic. (check-in: 6492e57e65 user: drh tags: branch-3.15) | |
| 20:24 | Fix the JSON1 extension so that the JSON validator correctly rejects malformed backslash escapes within string literals. (check-in: 7c46628380 user: drh tags: branch-3.15) | |
| 20:19 | Avoid a crash that can occur after an obscure OOM in the built-in INSTR() function. (check-in: 8a55b8e179 user: drh tags: branch-3.15) | |

| 19:40 | Take care not to try to generate code for the ATTACH and DETACH commands if there were syntax errors during parsing. Fix for ticket [2f1b168ab4d4844] (check-in: f8cf7ff156 user: drh tags: branch-3.15) | |
| 19:31 | Code constant vector components outside of any loops in CASE and BETWEEN expressions. Fix for [1a684656]. (check-in: c08aff13ea user: dan tags: trunk) | |

|
2016-11-18
| ||
| 20:49 | Add experimental sqlite3_snapshot_recover() API. (check-in: 174a6076a8 user: dan tags: serializable-snapshot) | |
| 18:43 | Require that the database handle be in autocommit mode for sqlite3_snapshot_get() to succeed. This is because it may open a read transaction on the database file. (check-in: 83b658dad0 user: dan tags: serializable-snapshot) | |

| 14:02 | When opening the *-shm file for a readonly database, try to open it in read-write mode before falling back to readonly. This is in case some other read/write connection within the same process uses the same file descriptor. (check-in: a07c581e88 user: dan tags: apple-osx) | |
| 13:54 | Change the --enable-debug option on configure so that it enables the ".selecttrace" and ".wheretrace" commands in the command-line shell. (check-in: 2331192b4c user: drh tags: trunk) | |
