| 15:44 | Merge the latest changes from trunk. Closed-Leaf check-in: 8183fa68 user: drh tags: skip-ahead-distinct | |
|
2016-04-15
| ||
| 22:03 | Add the SQLITE_SkipAhead optimization setting check-in: 87703b76 user: drh tags: skip-ahead-distinct | |
| 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: 6fac0b92 user: drh tags: skip-ahead-distinct | |
| 16:17 | Skip-ahead does not always work. So we still have to check for redundancy. check-in: db5a2364 user: drh tags: skip-ahead-distinct | |
| 15:54 | Fixes to the skip-ahead distinct logic. More issues remain. check-in: 45a70b2b user: drh tags: skip-ahead-distinct | |
| 15:06 | Merge enhancements from trunk, especially the ".eqp full" enhancement to the command-line shell. check-in: 491f0dbd user: drh tags: skip-ahead-distinct | |
| 14:13 | Several new test cases that cause failures. check-in: 0379f2cf user: drh tags: skip-ahead-distinct | |
| 13:24 | Fixed crash bugs. Still sometimes gets the wrong answers. check-in: 2afcb2c7 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: 9e14aa14 user: drh tags: skip-ahead-distinct | |
|
2016-04-14
| ||
| 19:29 | Work toward improving analysis and code generation for DISTINCT and aggregate queries. Leaf check-in: 129083bd user: drh tags: better-distinct-agg | |
| 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: 7b7a69d0 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: 79147dca user: dan tags: trunk | |
| 15:38 | Add some missing testcase() macros to the pushDownWhereTerms() routine. check-in: 67d7f79c user: drh tags: trunk | |
| 13:35 | Rename WhereInfo.pResultSet to pDistinctSet to more accurately reflect what it represents. check-in: 53179614 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: 7ee570e7 user: drh tags: trunk | |
| 13:06 | Additional ".selecttrace" debugging output when the query is transformed from a DISTINCT into a GROUP BY. check-in: 5a469145 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: 83cfe82c user: drh tags: trunk | |
|

| 16:43 | Simplification and performance improvements in sqlite3ExprDup() and its subroutines. More work is possible in this area. check-in: 476cc283 user: drh tags: trunk | |
| 16:35 | Rename the OP_MX_JUMP macro to SQLITE_MX_JUMP_OPCODE to avoid confusing the opcode name generator. check-in: e554a4c3 user: drh tags: trunk | |
| 14:49 | Performance improvement in sqlite3ExprDelete(). check-in: 60ad80e3 user: drh tags: trunk | |
| 13:36 | Remove the VdbeOp.opflags field and its associated initialization overhead. Update mkopcodeh.tcl to reorder opcode numbers to help the resolveP2Values() routine run faster. check-in: 099478fa user: drh tags: trunk | |
