| 16:27 | Skip-ahead is now just an optimization. If it gets confused, it falls back to an incremental scan with redundancy elimination. (check-in: 6fac0b9212 user: drh tags: skip-ahead-distinct) | |
| 16:17 | Skip-ahead does not always work. So we still have to check for redundancy. (check-in: db5a2364eb user: drh tags: skip-ahead-distinct) | |
| 15:54 | Fixes to the skip-ahead distinct logic. More issues remain. (check-in: 45a70b2bb8 user: drh tags: skip-ahead-distinct) | |
| 15:06 | Merge enhancements from trunk, especially the ".eqp full" enhancement to the command-line shell. (check-in: 491f0dbd63 user: drh tags: skip-ahead-distinct) | |
| 15:03 | CLI enhancement: Add the ".eqp full" option, that shows both the EXPLAIN QUERY PLAN and the EXPLAIN output for each command run. Also disable any ".wheretrace" and ".selecttrace" when showing EQP output. (check-in: 3e217d6265 user: drh tags: trunk) | |
| 14:13 | Several new test cases that cause failures. (check-in: 0379f2cff6 user: drh tags: skip-ahead-distinct) | |
| 13:24 | Fixed crash bugs. Still sometimes gets the wrong answers. (check-in: 2afcb2c752 user: drh tags: skip-ahead-distinct) | |
| 01:55 | Progress toward getting DISTINCT to use a seek to advance to the next distinct row, when driven by an appropriate index. (check-in: 9e14aa14cf user: drh tags: skip-ahead-distinct) | |

| 19:29 | Work toward improving analysis and code generation for DISTINCT and aggregate queries. (Leaf check-in: 129083bd5e user: drh tags: better-distinct-agg) | |
| 17:29 | In the ICU extension toupper() and tolower() SQL functions, avoid calling u_strToUpper() or u_strToLower() a second time if the buffer passed to the first invocation turns out to be large enough. (check-in: d23e581351 user: dan tags: trunk) | |
| 16:40 | Add the SF_HasAgg constant (currently unused). Also enhance the comments on many other constant definitions to detail constraints on their values. (check-in: 7b7a69d098 user: drh tags: trunk) | |
| 15:44 | Correctly interpret negative "PRAGMA cache_size" values when determining the cache-size used for sorting large amounts of data (i.e. the functionality in vdbesort.c). (check-in: 79147dca87 user: dan tags: trunk) | |
| 15:38 | Add some missing testcase() macros to the pushDownWhereTerms() routine. (check-in: 67d7f79c5e user: drh tags: trunk) | |
| 13:35 | Rename WhereInfo.pResultSet to pDistinctSet to more accurately reflect what it represents. (check-in: 5317961411 user: drh tags: trunk) | |
| 13:16 | Since the return value of sqlite3OsClose() is always ignored, we might as well make it "void" instead of "int", and thereby save 50 bytes in the compiled binary. (check-in: 7ee570e7a9 user: drh tags: trunk) | |
| 13:06 | Additional ".selecttrace" debugging output when the query is transformed from a DISTINCT into a GROUP BY. (check-in: 5a46914510 user: drh tags: trunk) | |

| 15:52 | Fixes for harmless compiler warnings. (check-in: 68142dc541 user: drh tags: trunk) | |
| 15:33 | Add the --indent option to the .schema and .fullschema commands in the shell, to enable simple but effective pretty-printing. (check-in: 83cfe82cd6 user: drh tags: trunk) | |

| 17:13 | Fix speedtest1 so that it automatically unlinks its test database prior to startup. (check-in: b65b69f6b6 user: drh tags: trunk) | |
| 16:59 | Add the --temp option to the speedtest1.c performance test program. (check-in: 8053a6e2bf user: drh tags: trunk) | |
| 16:23 | Improved localtime() support for WindowsCE (check-in: 662c32af02 user: drh tags: trunk) | |

| 18:15 | Performance optimizations in the column cache of the code generator, and especially the sqlite3ExprCacheRemove() routine. (check-in: e35b345cf8 user: drh tags: trunk) | |
| 16:43 | Simplification and performance improvements in sqlite3ExprDup() and its subroutines. More work is possible in this area. (check-in: 476cc28388 user: drh tags: trunk) | |
