| 18:48 | Fix typos in comments. Provided ".wheretrace" debugging output for the interstage heuristic module. Do omit automatic index loops in the interstage heuristic. (Leaf check-in: 357d9513 user: drh tags: branch-3.28) | |
| 18:31 | Fix table-valued functions so that they will work as the right table in a LEFT JOIN. Ticket [2ae0c599b735d59e] (check-in: 1f97086d user: drh tags: branch-3.28) | |
| 11:54 | Add a heuristic in between the two solver() passes of the query planner that tries to prevent a very slow query plan in cases where the output row count estimate is imprecise. (check-in: 74b247d9 user: drh tags: branch-3.28) | |

|
2023-10-19
| ||
| 21:05 | Ensure that when an ephemeral cursor is reopened with a second invocation of to OP_OpenEphemeral, the sequence counter is reset and the cache marked as stale. Fix for [9cdc5c46]. (check-in: d4bfa8d2 user: drh tags: branch-3.28) | |
|
2023-09-15
| ||
| 20:04 | Drop support for the view-scan optimization as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: 796a65fa user: drh tags: branch-3.28) | |
|
2023-02-26
| ||
| 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.

| 14:29 | Do not compute result columns of subqueries that are never used. Make those columns NULL instead. This optimization potentially resolves the enhancement request described by [ticket baa5bb76c35a124c]. (check-in: 0163b697 user: drh tags: branch-3.28) | |
| 01:29 | Do not compute unused result columns of subqueries. This optimization will potentially resolve the performance optimization request of [ticket baa5bb76c35a124c]. (Closed-Leaf check-in: 0c21b6a5 user: drh tags: branch-3.26) | |

|
2022-10-24
| ||
| 13:50 | Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: 3d1992de user: drh tags: branch-3.28) | |
|
2022-10-19
| ||
| 11:22 | If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28) | |
|
2022-09-27
| ||
| 17:00 | Fix a potential division by zero error in this version of RBU that might occur if an external client checkpoints a wal file created by a suspended RBU process. (Leaf check-in: 73edd93a user: dan tags: branch-3.14) | |
|
2022-09-01
| ||
| 10:41 | In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28) | |
|

|
2022-05-09
| ||
| 21:57 | Update this branch with latest changes from trunk, and the fts5 fix for "BEGIN CCONCURRENT" transactions. (check-in: c0135441 user: dan tags: begin-concurrent-report-wal2) | |
| 14:22 | Ensure that fts5 closes the read-only blob handle used to read the fts index at the end of each xUpdate operation. This doesn't matter for stock SQLite, as the handle will be closed in the subsequent xRollback or xSync call, but prevents "BEGIN CONCURRENT" transactions from being committed on this branch.

| 12:38 | Make a distinction between (1) WHERE clause constraints, (2) ON/USING constraints on outer joins, and (3) ON/USING clause constraints on inner joins. Formerly, there was no distinctionb between 1 and 3, but RIGHT JOIN needs to know the difference. Make RIGHT JOIN aware of this difference and add test cases. (check-in: 0f6f61c3 user: drh tags: right-join) | |
| 11:59 | Fix some comments that refer to LEFT JOIN that should refer to OUTER JOIN. No changes to code. (check-in: 5be5ede5 user: drh tags: right-join) | |

| 11:25 | Rename the Expr.w.iRightJoinTable to just Expr.w.iJoin, so that the words "RightJoin" in the former name do not lead readers to believe that this has something to do with RIGHT JOINs in particular. (check-in: e8c00442 user: drh tags: trunk) | |
| 10:38 | Ensure that the JT_LTORJ flag is preserved when flattening a subquery that is on the left side of a RIGHT JOIN. (check-in: ccb61fb1 user: drh tags: right-join) | |

| 23:48 | Cannot use an automatic index on the right table of a RIGHT JOIN because automatic indexes must be WHERE_IDX_ONLY, but the RIGHT JOIN post-processing does not know how to work with an index-only scan. (check-in: beb4401d user: drh tags: right-join) | |
| 23:01 | Revisit [f84b2beca7197589]: disallow co-routine implementations of tables that are to the left of a RIGHT JOIN, to avoid other complications. (check-in: cf00ebfc user: drh tags: right-join) | |
| 20:28 | Minor improvements to the sqlite3SrcListShiftJoinType() routine. This started out to be an effort to convert RIGHT JOIN to LEFT JOIN if the join was on the first pair of relations, but that messes up the "*" expansion and so won't work. (check-in: a48902c7 user: drh tags: right-join) | |
| 19:51 | When the left-most table of a RIGHT JOIN is implemented as a co-routine, make sure all its columns are flushed to NULL when it finishes so that they appear to be NULL during the RIGHT JOIN post-processing. (check-in: f84b2bec user: drh tags: right-join) | |

| 14:48 | Add byte-code that computes unmatched rows on the right table of a RIGHT JOIN. Compiles, and the code looks semi-reasonable, but still does not run. Incremental check-in. (check-in: 2db5a498 user: drh tags: right-join) | |
| 12:27 | The interior of the RIGHT JOIN loop is now a subroutine. (check-in: 549f5a7e user: drh tags: right-join) | |
| 03:16 | A few bits and bobs of code generation toward getting RIGHT JOIN to work. Much more remains to do. (check-in: 55b45431 user: drh tags: right-join) | |
| 03:12 | Merge the sqlite3WhereMalloc() routine from trunk into the right-join branch. (check-in: b1b3845a user: drh tags: right-join) | |
| 03:12 | Fix TCL extension build issue. (check-in: 0b3bb0e7 user: larrybr tags: cli_extension) | |
| 03:06 | The sqlite3WhereMalloc() routine allocates memory that is automatically deleted when the corresponding WhereInfo object is destroyed. (check-in: f237e1d8 user: drh tags: trunk) | |
| 02:31 | For shell extensions, generate a single-file header. For TCL extension, provide Makefile target, and make Tk opt-in rather than default. (a WIP) (check-in: 2cd49df5 user: larrybr tags: cli_extension) | |
|
2022-04-08
| ||
| 19:20 | Preliminary code to support RIGHT JOIN. Everything seems to work, except that the code to compute the unmatched rows for the RIGHT JOIN has not yet been added, so the result of a RIGHT JOIN is currently the same as an INNER JOIN. (check-in: 415abd67 user: drh tags: right-join) | |
| 17:01 | Enhance the sqlite_dbpage fix at check-in 642a0b4752743 from about a month ago such that it still takes a transaction on all attached databases, but it only starts a read transaction for read-only operations, rather than starting a write transaction for everything. (check-in: 8efd61e8 user: drh tags: trunk) | |
| 15:11 | Improved explanation and commentary on the sqlite3JoinType() routine. One of the error messages changes slightly, but besides that everything works the same. (check-in: 48f2e5a1 user: drh tags: trunk) | |
| 12:50 | Grammar rules for a hypothetical FOR EACH ROW statement. No new keywords required. However, the sqlite3_complete() machine had to be reworked because of the fact that FOR EACH ROW can contain internal semicolon tokens. (Leaf check-in: 32ae9ee7 user: drh tags: foreachrow-statement) | |
| 10:35 | Tokenizer and grammar rules sufficient for the MERGE command. (Leaf check-in: 2deee326 user: drh tags: merge-statement) | |

| 19:06 | Enhance the EXPLAIN output formatting in the CLI so that the subroutine that implements the loop body for the multi-index OR optimization is indented. (check-in: c2965fea user: drh tags: trunk) | |
| 18:17 | The ".testctrl optimizations 0x400000" command disables the generation of OP_ReleaseReg opcodes. OP_ReleaseReg opcodes are usually only generated for SQLITE_DEBUG builds and are used to verify that registers are descoped propertly. But they can get in the way of code understanding when studying bytecode dumps. So this new optimization setting is provided to temporarily turn OP_ReleaseReg opcodes off. (check-in: fa527672 user: drh tags: trunk) | |
| 14:13 | Fix the parsing of C-style comments in Lemon, as reported by forum post b6edc69548. This has no affect on SQLite itself. (check-in: 201569e0 user: drh tags: trunk) | |
| 14:03 | Optimization to sqlite3TriggersExist() saves over 700K CPU cycles. (check-in: 5043a350 user: drh tags: trunk) | |
| 13:48 | Avoid compiler warnings about the new sqlite3Show() debugging routines begin "defined but not used". (check-in: 47ddc269 user: drh tags: trunk) | |
| 12:10 | Omit an unnecessary initialization in tokenExpr(). (check-in: 8f6ae686 user: drh tags: trunk) | |

| 06:33 | For TCL extension: Adjust provided "gui" command, and document it. For shell: Separate shell variables from binding parameters, mainly so they live longer, in the shell DB. Add .vars dot command to reflect this separation, and specialized for shell variables. Much code shuffling to share code between .parameters and .vars commands. (check-in: fa492ff5 user: larrybr tags: cli_extension) | |

| 22:57 | In setResultStrOrError(), if the input string pointer is NULL and hence the value gets set to an SQL NULL, then the Mem.enc field is uninitialized. So do not read it. This is a harmless OSSFuzz/ASAN found problem. (check-in: 47d0b1c4 user: drh tags: trunk) | |
| 21:11 | For TCL extension: Cleanup TCL library interaction and interpreter management. Group code into more purpose oriented functions. Add .unknown dot command, delegating to TCL commands with "dot" names. Drop planned .eval new dot command. For shell: Implement undocumented .unknown dot command, doing little. Make dispatcher call .unknown's implementation for unknown dot command. Fix a command lookup bug exposed by above change to unknown handling. Add .eval dot command. Add options to .x command aimed at control of errors in command sequences. (a WIP) Make dispatcher report ambiguous dot command lookups, even with no extension.
