| 23:08 | Convert invalid surrogates to 0xfffd when translating UTF. (check-in: 7fab1393c2 user: drh tags: trunk) | |
| 19:25 | A better (smaller and faster) solution to ticket [4374860b29383380]. (check-in: abc473fb8f user: drh tags: trunk) | |
| 00:12 | • Fixed ticket [4374860b29]: Segmentation fault in isAuxiliaryVtabOperator plus 5 other changes (artifact: 971c60ab36 user: drh) | |
| 00:12 | Take care when checking the table of a TK_COLUMN expression node to see if the table is a virtual table to first ensure that the Expr.y.pTab pointer is not null due to generated column optimizations. Ticket [4374860b29383380]. (check-in: 9d0d4ab95d user: drh tags: trunk) | |

| 20:22 | Add support for "brotli" compression to the zonefile module. (check-in: 3eb25b3fa5 user: dan tags: zonefile) | |
| 19:38 | Add support for compression types "lz4" and "lz4hc" to the zonefile module. (check-in: bbe5b21ffa user: dan tags: zonefile) | |
| 18:33 | Add support for compression methods "zstd" and "zstd_global_dict". (check-in: a993a50bb8 user: dan tags: zonefile) | |
| 07:38 | Fix a data race causing a tsan complaint with SQLITE_ENABLE_API_ARMOR builds on unix. The race condition is not dangerous in practice, it just upsets tsan. (check-in: f53b8a573b user: dan tags: trunk) | |

| 23:52 | Fix the #endif location for an #ifndef SQLITE_UNTESTABLE macro in the command-line shell. (check-in: 8cc9d74c17 user: drh tags: trunk) | |
| 21:23 | Increase the estimated cost of sorting when sorting wide results sets, to account for the extra storage space and I/O required for the external sort. (Leaf check-in: 38298ef923 user: drh tags: apple-increased-sorting-cost) | |
| 19:24 | The analyze_as_needed pragma now responds to table size growth and will automatically rerun the analysis after each 10x size increase. (check-in: bfbdd07409 user: drh tags: auto-analyze) | |
| 16:26 | Add the "PRAGMA analyze_as_needed" command. (check-in: e93db23731 user: drh tags: auto-analyze) | |
| 15:26 | Set the TF_StatsUsed flag on tables when the query planner outcome is affected by the sqlite_stat1 data. Also, change the column names of the "PRAGMA stats" command so that they are not keywords. (check-in: fb2b8ae831 user: drh tags: auto-analyze) | |
| 13:38 | Enhance the Index and Table objects so that they remember if their stats come from the sqlite_stat1 table. Make the "PRAGMA stats" an SQLITE_DEBUG only pragma. Add the flags column to "PRAGMA stats". These are all preliminary steps toward a "PRAGMA analyze_ifneeded;" feature. (check-in: 85026c8ee1 user: drh tags: auto-analyze) | |
| 02:07 | Merge fixes from trunk. (Leaf check-in: 662e8ccf7e user: drh tags: increased-sorting-cost) | |
| 02:04 | Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. (check-in: 218b2bbb0d user: drh tags: trunk) | |
| 01:43 | Enable the ".wheretrace" and ".selecttrace" extensions in the command-line shell when compiled on Windows using DEBUG=3 or higher. Fix a harmless warning in the shell that comes up when compiled this way. (check-in: 8a03be1dc4 user: drh tags: trunk) | |

| 20:47 | When VDBE opcodes fail, they cause an immediate exit from the loop, rather than depending on the rc==SQLITE_OK test at the top of the loop. This is faster and smaller. (check-in: 24c7151c1a user: drh tags: trunk) | |
| 20:06 | Schemalint changes: Avoid creating candidate indexes if a compatible index exists. Do not quote identifiers that do not require it. (check-in: cf0f7eeb4f user: dan tags: schemalint) | |
| 18:44 | Fix up all VDBE opcodes so that they cause an immediate exit on any kind of error, and thereby eliminate the need to test "rc" at the top of the loop. Resulting code is a little smaller and faster. (Closed-Leaf check-in: a444633a82 user: drh tags: vdbe-performance) | |
| 15:01 | Bump the version number to 3.12.0. (check-in: c17d7276b8 user: drh tags: trunk) | |
| 14:48 | Remove the "#ifdef SQLITE_TEST" condition from fts5_test_mi.c. Update fts5_main.c so that if SQLITE_FTS5_TEST_MI is defined when it is built the fts5_test_mi.c entry point is automatically called. This makes it easier to build versions of fts5 that include the matchinfo() demo by default. (check-in: 87e6e225ae user: dan tags: trunk) | |
| 14:11 | Improve test coverage of demo code in fts5_test_mi.c. (check-in: 8a78050dc0 user: dan tags: trunk) | |
| 13:24 | Enhance Lemon to generate more compact and efficient code for yy_reduce(). Update the main SQL grammar to take advantage of the new capabilities. (check-in: 53fd040c98 user: drh tags: trunk) | |
| 12:34 | More agressive use of /*A-overwrites-X*/ in the parser. Fix an off-by-one error in parser stack overflow detection. (Closed-Leaf check-in: 417e777701 user: drh tags: parser-performance) | |
| 11:13 | Documentation typo on sqlite3_wal_hook(). No changes to code. (check-in: fc2043ebaa user: drh tags: trunk) | |
| 04:33 | Enhance Lemon so that if reduce code contains a comment of the form "/*A-overwrites-X*/" then a LHS label A is allowed to overwrite the RHS label X. (check-in: 5cfe9545d4 user: drh tags: parser-performance) | |
| 01:46 | Further improvements to the Lemon-generated code for yy_reduce(). (check-in: ef95a7d649 user: drh tags: parser-performance) | |
| 01:18 | In Lemon, add the ability for the left-most RHS label to be the same as the LHS label, causing the LHS values to be written directly into the stack. (check-in: 4bb94c7c4c user: drh tags: parser-performance) | |

| 15:58 | Remove a no-op code path from sqlite3ExprIsInteger(). Replace it with an assert() that proves it always does nothing. (check-in: 7af66d1bd5 user: drh tags: trunk) | |
| 13:52 | Remove an assert() that was made redundant by the previous checkin. (check-in: 21db719156 user: drh tags: trunk) | |
| 13:33 | Add an ALWAYS() around a always-true test in where.c. (check-in: 8123283ee1 user: drh tags: trunk) | |

| 15:01 | Fix bug preventing compliation without MEMDEBUG when ENABLE_MEMORY_MANAGE is defined. (CVS 3105) (check-in: 76912b33b1 user: danielk1977 tags: trunk) | |
| 12:25 | Ensure temp db is open before executing a pragma like "temp.cachesize = xxx". Fix for #1682. (CVS 3104) (check-in: 1e4644b236 user: danielk1977 tags: trunk) | |
