| 20:04 | Change the name of SQLITE_DBCONFIG_STMT_SCANSTATS to SQLITE_DBCONFIG_STMT_SCANSTATUS. (check-in: a63e4a15 user: dan tags: trunk) | |
| 19:39 | Add an sqlite3_db_config() option - SQLITE_DBCONFIG_STMT_SCANSTATS - for enabling and disabling the collection of sqlite3_stmt_scanstats() statistics in SQLITE_ENABLE_STMT_SCANSTATUS builds. Collection of statistics is disabled by default. (check-in: 0f5579be user: dan tags: trunk) | |
| 18:06 | Only use a Bloom filter on an automatic index if one or more of the key columns in the index can take on non-TEXT values. (check-in: 5916705c user: drh tags: trunk) | |
| 14:28 | In the Bloom filter optimization, hash all strings and blobs into the same value, because we do not know if two different strings might compare equal even if they have different byte sequences, due to collating functions. Formerly, the hash of a string or blob was just its length. This could all be improved. Fix for the issue reported by forum post 0846211821. (check-in: 090304b8 user: drh tags: trunk) | |
| 13:46 | When an automatic index creates a Bloom filter, show that in the EXPLAIN QUERY PLAN output. (check-in: d7b2ac1c user: drh tags: trunk) | |

| 21:53 | Make the "unref" operation on database pages a method which is part of the PgHdr object. This is a potential performance optimization. (Leaf check-in: 37c5c8aa user: drh tags: unref-opt) | |
| 18:55 | Minor performance optimization in the computation of an affinity string for an index. (check-in: 07334aa1 user: drh tags: trunk) | |
| 14:48 | Further to [46639f682975dac6], the parameters of a table valued function that is on the left side of a RIGHT JOIN do not need to be in the ON clause. Add new test cases and tags to associated test cases with the code. (check-in: 18ee689d user: drh tags: trunk) | |
| 07:23 | Minor doc tweak for the previous commit. (check-in: a8832164 user: stephan tags: trunk) | |

| 21:09 | When a table-valued function appears as the right table of a RIGHT JOIN, the argument constraints on the table-valued function should be considered part of the ON clause of the RIGHT JOIN. (check-in: d225d077 user: drh tags: branch-3.41) | |
| 20:57 | When a table-valued function appears as the right table of a RIGHT JOIN, the argument constraints on the table-valued function should be considered part of the ON clause of the RIGHT JOIN. Fix for the problem reported by forum post 422e635f3beafbf6. Test cases in TH3. Possibly related to the enhancement at [501609eddf2a46d5]. (check-in: 46639f68 user: drh tags: trunk) | |
| 19:36 | Correct substantive error (DML and DQL versus DML) of last check-in. (Leaf check-in: 703fa854 user: larrybr tags: db_config_ops_rewrite) | |
| 19:10 | Revise doc for SQLITE_DBCONFIG_* options, for clarification and coverage of all vararg parameters. Also, a grammo nit swat. (check-in: aa25596b user: larrybr tags: db_config_ops_rewrite) | |
| 11:52 | In the omit-unused-subquery-columns optimization, be sure to remove the EP_Skip and EP_Unlikely flags from the result set expressions that get nulled-out. dbsqlfuzz bf1d3ed6e0e0dd8766027797d43db40c776d2b15. Also fix an incorrect ".selecttrace" code block. (check-in: 83a7f13e user: drh tags: branch-3.28) | |
| 11:36 | In the omit-unused-subquery-columns optimization, be sure to remove the EP_Skip and EP_Unlikely flags from the result set expressions that get nulled-out. dbsqlfuzz bf1d3ed6e0e0dd8766027797d43db40c776d2b15. (check-in: 21aec65e user: drh tags: trunk) | |

| 15:34 | Remove an unnecessary and redundant corruption checks in defragmentPage(). (check-in: 2dc7342e user: drh tags: trunk) | |
| 15:15 | Revert (mostly) to earlier CLI response to -echo and SQL at the command line. (check-in: 1c6cfcf6 user: larrybr tags: trunk) | |
| 12:50 | Performance optimization on sqlite3_vsnprintf(). (check-in: 4430e6e9 user: drh tags: trunk) | |
|
2023-02-24

| 21:23 | Add the "on" option to the ".log" command in the CLI. Allow ".log on" and ".log off" even in --safe mode. Enable the .log command for fiddle builds. (check-in: 6bba9100 user: drh tags: trunk) | |

| 13:45 | Adjust testrunner.tcl to make use of the new number_of_cores TCL command available in testfixture, and to use no more than half the available cores. (check-in: e0122d38 user: drh tags: trunk) | |
| 13:25 | Add the "number_of_cores" TCL command to the testfixture. (check-in: 16ee5a7b user: drh tags: trunk) | |
| 12:55 | Merge enhancements from trunk into the anytime-config branch. (check-in: 04b2fdf3 user: drh tags: anytime-config) | |
| 11:54 | Slightly faster and more precise floating-point to decimal conversion. See forum thread d1387c3979c7f557 for discussion. (check-in: 6dea6f47 user: drh tags: trunk) | |
| 01:37 | A simpler fix to the problem described by forum thread d1387c3979c7f557. See specifically post 2d2ddc5b70c31de5. This approach is simpler, but it also runs a little slower. (Closed-Leaf check-in: 334d22bc user: drh tags: fp-conversion-simpler) | |
| 01:08 | Fix an incorrect optimization that was attempted as part of check-in [18de3a8e6b431a07]. (Closed-Leaf check-in: f32055e8 user: drh tags: fp-conversion) | |
|

| 21:18 | Increased precision of floating-point to decimal conversions when the floating point value has no fractional part. Forum post d1387c3979c7f557 (check-in: 18de3a8e user: drh tags: fp-conversion) | |
| 17:12 | Provide -DHAVE_LOG2=0 and -DHAVE_LOG10=0 compile-time options for use on systems that lack the log2() and log10() standard math library routines, to cause SQLite to substitute its own alternatives. (check-in: ff3362ab user: drh tags: branch-3.41) | |
| 14:43 | Fix harmless compiler warnings and a code indentation error. (check-in: de6c5c6b user: drh tags: trunk) | |
| 14:22 | Allow the sqlite3_config() interface to be invoked at any time for a few choosen options: SQLITE_CONFIG_LOG, SQLITE_CONFIG_URI, and SQLITE_CONFIG_PCACHE_HDRSZ. This list will likely change before release. (check-in: e1702eb4 user: drh tags: anytime-config) | |
| 01:52 | Provide -DHAVE_LOG2=0 and -DHAVE_LOG10=0 compile-time options for use on systems that lack the log2() and log10() standard math library routines, to cause SQLite to substitute its own alternatives. (check-in: 7ee22f95 user: drh tags: trunk) | |

| 21:47 | Enable the count-of-view optimization by default. Enhancement request [eaed8e36ce888f1e]. (check-in: a4aacdd3 user: drh tags: trunk) | |
| 21:11 | Avoid computing the values for unused result-set columns in subqueries. Performance optimization request [baa5bb76c35a124c]. (check-in: 7c2d3406 user: drh tags: trunk) | |
| 20:50 | Update the version number to 3.42.0 to begin the next development cycle. (check-in: 65910216 user: drh tags: trunk) | |
| 20:42 | Remove the push-down optimization restriction that was added by check-in [1ad41840c5e0fa70] because it is no longer needed after the enhancements to compound query processing in check-in [27655c9353620aa5] This resolves the performance regression reported by forum post bcc4375032.

| 15:54 | Do not perform the omit-unused-subquery-columns optimizations on a subquery that is DISTINCT, as that can lead to incorrect results. (check-in: cc148503 user: drh tags: omit-unused-subquery-columns) | |
