| 15:16 | Remove an unused parameter from fts5ConfigParseSpecial(). Compiler-warning fix only - no functional changes. (check-in: c08dd245f7 user: drh tags: trunk) | |
| 15:08 | Use a heuristic of artifically lowering the cost of fact tables in a star-schema query in order to prevent plans where the fact tables are in outer loops from being trimmed by the path limiter. This helps to generate better (faster) query plans in those particular cases. (check-in: 38db9b5c83 user: drh tags: trunk) | |
| 14:32 | Change an assert() (incorrectly) added by the previous check-in into a testcase(). (Closed-Leaf check-in: 5e64b541d1 user: drh tags: star-schema) | |
| 14:04 | Small performance enhancement in wherePathSolver() (check-in: bdab69641d user: drh tags: star-schema) | |
| 13:29 | Improvements to comments and debugging output. (check-in: 85164ee155 user: drh tags: star-schema) | |
| 10:40 | Remember the amount of the heuristic cost adjustment associated with star schemas and compensate when computing whether or not to use Bloom filters. (check-in: 21daf2463e user: drh tags: star-schema) | |
| 09:53 | Fix typos in the star-schema test cases. (check-in: 4080937353 user: drh tags: star-schema) | |
| 09:41 | • Edit [b31933d87301bd93|b31933d873]: Edit check-in comment. (artifact: 3a34f16e85 user: drh) | |
| 03:35 | Fix sqldiff out-of-bounds char classification error mentioned in the forum. (check-in: b31933d873 user: larrybr tags: trunk) | |
| 00:38 | Use a heuristic in the query planner to help it better cope with large star schema queries. (check-in: a98be0f548 user: drh tags: star-schema) | |

| 20:33 | New date/time modifier: (+|-)YYYY-MM-DD HH:MM(:SS.SSS)? (check-in: 3832b8a9ef user: drh tags: timediff) | |
| 18:01 | Prototype implementation of a proposed "timediff(X,Y)" SQL function. (check-in: 054a195125 user: drh tags: timediff) | |

| 23:07 | Do not confuse the ">" operator with IS NOT NULL when checking to see if a partial index is usable. Forum post d813704d7c. (check-in: 8cc23931d6 user: drh tags: trunk) | |
| 21:50 | Fix a subtle error in an assert(). dbsqlfuzz eefbd0215c0c1b4bcc32b8141b48b35f7b431300 (check-in: a5ec81eb49 user: drh tags: trunk) | |

| 21:06 | Enhancements to the incremental build support for MSVC. (check-in: 2e25d915bc user: mistachkin tags: trunk) | |
| 20:16 | Remove a stray "&" character in the CLI, detected by a clang warning. (check-in: 5865d2f2d0 user: drh tags: trunk) | |
| 19:45 | Add the "shelltest" target to the MSVC makefile as well. (check-in: 9924c0456b user: drh tags: trunk) | |
| 19:39 | Fix the ".import" command of the CLI to clean up better after errors. Add the new "shelltest" makefile target on unix platforms. (check-in: 50d4ddf133 user: drh tags: trunk) | |
| 19:17 | Improvements to help text for the CLI. (check-in: 6a01e4c444 user: drh tags: trunk) | |
| 19:03 | Fix a memory leak in the CLI when an unknown or unrecognized argument is given to the ".dump" command. (check-in: 71bfbbcc1a user: drh tags: trunk) | |
| 16:15 | Improvements to columnar output in the CLI. Columns automatically expand to contain the largest row. (check-in: 4e1db8e9a9 user: drh tags: trunk) | |
| 14:38 | Space to hold the ".width" of columns in the CLI is now obtained from malloc() and hence is not limited in the number of columns supported. (check-in: 445ed5dab2 user: drh tags: trunk) | |
| 12:31 | Incremental improvements to tabular output modes in the CLI. The "markdown" and "table" modes no have headers turned on by default. (check-in: af28bff91a user: drh tags: trunk) | |
| 11:07 | Expand upon a comment in os_unix.c. No changes to code. (check-in: 77933dc4db user: dan tags: trunk) | |
| 00:21 | In the json output mode of the CLI, do correct quoting of escape characters. Also, show BLOBs as JSON strings, possibly with embedded \u0000 bytes. (check-in: 0278147a7d user: drh tags: trunk) | |

| 19:04 | Import recent enhancements from trunk. (check-in: 54bec164eb user: drh tags: sessions) | |
| 19:00 | Add extra tests and fixes for multi-column matches. (check-in: ae6794ffa2 user: dan tags: fts5) | |
| 18:42 | Ensure that allocateBtreePage() always clears the MemPage pointer when it fails due to an I/O or memory allocation error. (check-in: 09a38bf665 user: drh tags: trunk) | |
| 17:51 | Move two unreachable conditionals inside of NEVER() or assert(). (check-in: db4e9728fa user: drh tags: trunk) | |
| 17:13 | Remove a corruption test in balance_nonroot that is superceded by a prior better check. (check-in: 00693682d8 user: drh tags: trunk) | |
| 15:55 | Add syntax to fts5 used to specify that a phrase or NEAR group should match a subset of columns. For example "[col1 col2 ...] : <phrase>". (check-in: 0fc0ea2092 user: dan tags: fts5) | |
| 15:15 | Omit the rowallock.test script (Read-Only WAL lock) from the inmemory_journal permutation. (check-in: d21db33089 user: drh tags: trunk) | |
| 14:47 | Add support for automatic indexes on FROM-clause subqueries that are implemented via co-routine. (check-in: 020b8b106f user: drh tags: trunk) | |
| 14:36 | Add some extra source-code comments and a test case. (Closed-Leaf check-in: 6d410442fb user: drh tags: coroutine-autoindex) | |
| 13:55 | An attempt to allow automatic index creation on subqueries accessed via co-routine. (check-in: 521345add6 user: drh tags: coroutine-autoindex) | |
| 01:35 | Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d7e user: drh tags: trunk) | |
