| 02:37 | Avoid computing cell sizes in balance_nonroot() until they are really needed. This gives an overall 1.7% performance gain for about 1000 extra bytes of code space. (check-in: 43844537 user: drh tags: btree-opt2) | |
|

| 20:02 | Change the way that balance_nonroot() partitions cells between the sibling pages such that a scan of the cell size array is not required. (check-in: 16872871 user: drh tags: btree-opt2) | |

| 18:13 | Split out all four cases of cellSizePtr() into different methods, each optimized for the specific page type. This gives a 0.36% performance increase at a cost of about 300 bytes of code. (Leaf check-in: 522502ec user: drh tags: btree-opt) | |
| 14:11 | Update the fuzztest data using the latest test vectors discovered by AFL. (check-in: b97f9cf7 user: drh tags: trunk) | |
| 13:18 | Make sure that the likelihood() function does not mess up generation of result-set code when it is used (inappropropriately) in a result-set expression. (check-in: 7cdbae62 user: drh tags: trunk) | |

| 20:31 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: 172a864d user: drh tags: trunk) | |
| 20:08 | Fix corner cases involving corrupt varint values in record headers. (Closed-Leaf check-in: 3189116b user: drh tags: btree-opt) | |
| 18:24 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: faab0ed9 user: drh tags: btree-opt) | |
| 17:19 | Add the MemPage.xParseCell method and provide various implementations (variations on the former btreeParseCellPtr()) depending on the page type. (check-in: 41d03d88 user: drh tags: trunk) | |
| 15:07 | Make cellSizePtr() a method on the MemPage object, with alternative implementations depending on the page type. This results is a small performance improvement and size reduction. (check-in: 02f7e9d7 user: drh tags: trunk) | |

| 15:26 | Further #ifdef changes in speedtest1.c in order to support SQLite back to version 3.3.9 and perhaps even earlier. (check-in: 9246eca5 user: drh tags: trunk) | |
| 14:32 | Pervent the likelihood() function from moving ON clause terms of a LEFT JOIN into the WHERE clause. Fix for ticket [5f60b11fc8e23490e2] (check-in: ed96e14a user: drh tags: trunk) | |
| 14:09 | Show the values of Expr.flag in the AST of ".selecttrace" (check-in: a84d1004 user: drh tags: trunk) | |
| 12:37 | Add #ifdefs to some features speedtest1.c so that it compiles with older versions of SQLite, going back to version 3.5.1. (check-in: f50dd154 user: drh tags: trunk) | |

| 23:28 | Performance improvement in sqlite3VdbeMemShallowCopy() for the common case where the receiver does not require prior resource deallocation. (check-in: d718ea36 user: drh tags: trunk) | |
| 19:06 | Use 'binary' mode for popen with MSVC. (Closed-Leaf check-in: 7b84641e user: mistachkin tags: popenMsvc) | |
| 18:57 | Improve spacing and comment style for the shell. No changes to code. (check-in: 5b547da0 user: mistachkin tags: trunk) | |
| 18:24 | Improved comments on the fuzzcheck.c test program. No changes to code. (check-in: a7e27d19 user: drh tags: trunk) | |
| 17:08 | Fix a uninitialized variable use in the command-line shell when the ".open" command is invoked without any arguments. (check-in: fc4f4d1e user: drh tags: trunk) | |
| 13:20 | Performance optimization and comment fixes for the LIKE and GLOB operators. (check-in: c89d7726 user: drh tags: trunk) | |
| 02:11 | Make getCellInfo() a real function instead of a macro, for a size reduction and a 0.2% performance gain. (check-in: 55c393ea user: drh tags: trunk) | |
| 01:31 | Optimizations to two VDBE accessory routines for a 0.2% performance increase. (check-in: 66d033b9 user: drh tags: trunk) | |
|

| 16:39 | Ensure that the CREATE TABLE AS statement correctly undoes partial changes to the sqlite_master table if the SELECT on the right-hand side aborts with an error. Fix for ticket [873cae2b6e25b] (check-in: 400e025e user: drh tags: trunk) | |

| 16:40 | Adjust ICU tests to account for recent changes in the official Unicode definition of whitespace. (check-in: 08165253 user: drh tags: trunk) | |
| 16:09 | Fix a harmless comment typo. No code changes. (check-in: ae687652 user: drh tags: trunk) | |
| 14:43 | Fix harmless compiler warnings. (check-in: b0badb99 user: drh tags: trunk) | |
