| 15:03 | Fix a couple of assert() statements that were failing with OOM error tests. (check-in: 8eb3d7d836 user: dan tags: rbu-vacuum) | |

| ||
| 22:03 | Add the SQLITE_SkipAhead optimization setting (check-in: 87703b7661 user: drh tags: skip-ahead-distinct) | |
| 20:46 | Add the experimental sqlite3rbu_vacuum() API function. For opening an RBU handle that rebuilds a database from scratch. (check-in: 0216b48f28 user: dan tags: rbu-vacuum) | |
| 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) | |
|

| 19:20 | Merge enhancements from trunk via tempfiles-lazy-open. (check-in: ae16310c4e user: drh tags: tempfiles-25) | |
| 16:52 | On commit, flush dirty temp-file pages only if the file is already open and 25% or more of the cache is dirty. (check-in: f6babf2920 user: dan tags: tempfiles-25) | |

| 15:14 | Update the documentation for sqlite3_snapshot_cmp() to make the circumstances under which the comparison is valid clearer. Add tests for the same. (Closed-Leaf check-in: 8fc834741b user: dan tags: snapshot-cmp) | |
