| 18:16 | Add fts5_source_id() SQL function, similar to sqlite_source_id(). (check-in: ec2573487c user: dan tags: trunk) | |
| 16:52 | Fix harmless compiler warnings and one macro VVA_ONLY macro usage issue. (check-in: bcc8a75509 user: mistachkin tags: trunk) | |
| 16:50 | Simplify FTS5 handling in the MSVC makefile. (check-in: f022e04343 user: mistachkin tags: trunk) | |

| 19:59 | Avoid create a stack from in sqlite3BackupUpdate() in the common case where the first argument is NULL. (check-in: 2a897b9e94 user: drh tags: trunk) | |
| 17:53 | Simplification of PRAGMA integrity_check logic. Make sure that the depth of the right-most subtree is correct. Size reduction and performance increase, with no change in output. (check-in: 550705fcb6 user: drh tags: trunk) | |
| 17:13 | Rework the PRAGMA integrity_check logic. Simplify the checkTreePage() routine and clean up the error messages generated. (Closed-Leaf check-in: 1c52212369 user: drh tags: integrity-check-refactor) | |

| 01:31 | Change integrity_check to analyze the cells of a page in reverse order, as this will tend to insert the cells into the analysis heap in increasing order by address, which is the most efficient way to load a min-heap. (check-in: 59ad912c4c user: drh tags: trunk) | |

| 12:47 | Make use of htonl() and __builtin_bswap32() for faster implementations of sqlite3Get4byte() and sqlite3Put4byte(). (check-in: bc27ebd7f7 user: drh tags: bswap-functions) | |
| 11:07 | Change an unreachable branch into an assert() in sqlite3PagerAcquire() and optimize sqlite3PcacheOpenSavepoint() by factoring out rarely used code into a subroutine. (check-in: b406b20ecd user: drh tags: trunk) | |

| 23:01 | From sqlite3BtreeInsert(), bypass the btreeMoveto() routine for table inserts and go directly to sqlite3BtreeMovetoUnpacked(). (check-in: 53fe685d56 user: drh tags: trunk) | |
| 20:53 | Add a bypass path in sqlite3PagerWrite() for pages with the PGHDR_WRITEABLE bit set, for about a 1% performance increase. (check-in: ba425a6abb user: drh tags: trunk) | |

| 04:21 | Add the new PGHDR_CLEAN bit to PgHdr.flags in pcache.c. This bit is always the opposite of PGHDR_DIRTY. Use the extra bit to avoid a comparison for a small performance boost. (check-in: 8619fc346d user: drh tags: trunk) | |
| 03:28 | Very small size reduction and performance increase in sqlite3BitvecTest(). (check-in: 9b3a7281bd user: drh tags: trunk) | |
