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) | |

18:18 | Merge all recent enhancements and fixes from trunk. (check-in: 199bfb67 user: drh tags: sessions) | |
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) | |
