| 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: 74b247d958 user: drh tags: branch-3.28) | |
|
2023-11-29
| ||
| 16:26 | Fix a duplicate assert() caused by the second cherrypick in the previous check-in. (check-in: f10d4fc4a8 user: drh tags: branch-3.28) | |
| 16:07 | Remove Window objects from the corresponding Select.pWin list when they are deleted, as they are, for example, when the ORDER BY clause is optimized out. (check-in: f9c6e6a710 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: d4bfa8d21a 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: 796a65fa61 user: drh tags: branch-3.28) | |
|
2023-02-26
| ||
| 11:52 | In the [/info/7c2d3406000dc8ac|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: 83a7f13edb user: drh tags: branch-3.28) | |
|
2023-02-16
| ||
| 21:01 | Fix an #ifdef that uses a different macro name from the main branch. (check-in: ad6ac5d3e8 user: drh tags: branch-3.28) | |
| 19:04 | Back-port omit-unused-subquery-column enhancements into the 3.28 branch. (check-in: 57a4e91f43 user: drh tags: branch-3.28) | |
| 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 [baa5bb76c35a124c|ticket baa5bb76c35a124c]. (check-in: 0163b697dd 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 [baa5bb76c35a124c|ticket baa5bb76c35a124c]. (Closed-Leaf check-in: 0c21b6a5f8 user: drh tags: branch-3.26) | |
| 01:21 | Update test cases so that they work with TCL 8.7 and later. (check-in: e9b762de0e user: drh tags: branch-3.26) | |
|
2023-02-15
| ||
| 13:00 | Update the configure script so that it contains the correct version number. (check-in: a7cbf30808 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: 3d1992de47 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: 3da1032878 user: drh tags: branch-3.28) | |
|
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: e3754cc188 user: drh tags: branch-3.28) | |
|
2022-08-10
| ||
| 17:03 | Merge the branch-3.28a fixes into branch-3.28. (check-in: ba6bf33147 user: drh tags: branch-3.28) | |
|

| ||
| 20:22 | Fix a rounding error caused by scalar->logarithm->scalar conversion when using stat4 data to estimate some range scans. (check-in: 68d86f2b20 user: drh tags: branch-3.28) | |
|
2021-08-11
| ||
| 18:56 | Fix an RBU problem with restarting an update after the *-oal file is already larger than 4GiB. (Leaf check-in: 56869f54f3 user: dan tags: rbu-replace-hack) | |
| 18:44 | If the special "sqlite_rbu_replace_hack" table is present in an RBU database, use REPLACE instead of INSERT when writing index entries to imposter tables. (check-in: 4b73e151cd user: dan tags: rbu-replace-hack) | |
|
2021-07-13
| ||
| 15:30 | Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. This allows the SQL associated with CVE-2020-13871 (ticket [c8d3b9f0a750a529]) to be tested. (Closed-Leaf check-in: d2e6722037 user: dan tags: branch-3.28a) | |
|
2021-07-12
| ||
| 14:38 | Fix a defect in the query-flattener optimization identified by ticket [8f157e8010b22af0]. This fix is associated with CVE-2020-15358. (check-in: 9e001b635f user: dan tags: branch-3.28a) | |
|
2021-02-11
| ||
| 16:19 | In RBU, avoid passing VFS xShmLock calls through to the underlying VFS in cases where xShmMap calls may not be. This fixes a bad interaction with ZipVFS. (Leaf check-in: 0c3838d951 user: dan tags: reuse-schema-3.31) | |
|
2020-10-22
| ||
| 18:58 | Minor tweaks to query planning weights so that when STAT4 is enabled and functioning, a full table scan is more likely to be selected if that seems like the fastest solution. Only do this when STAT4 info is available because an error has a large potential downside. (check-in: 263293f1e6 user: drh tags: branch-3.28) | |
|
2020-10-02
| ||
| 13:57 | Import further corner-case fixes for the in-scan-vs-index or OP_SeekScan optimization from trunk. (check-in: c144d6404f user: drh tags: branch-3.28) | |
| 12:11 | For the OP_SeekScan optimization, the OP_IdxGT does not necessarily come right after the OP_SeekGE. So use the P2 operand of OP_SeekScan to point to the first instruction after OP_IdxGT. Problem found by dbsqlfuzz. (check-in: ec37744c6e user: drh tags: branch-3.28) | |
| 02:07 | Disable the OP_SeekScan opcode of the in-scan-vs-index optimization when in PRAGMA reverse_unordered_selects mode, as the OP_SeekScan only works with forwards scans. Thanks to OSSFuzz for pointing out the problem to us. (check-in: 9a1cdf7e9c user: drh tags: branch-3.28) | |
|
2020-09-30
| ||
| 18:22 | Improved query optimization for multi-column indexes where the second or later columns are constrained by an IN operator and the earlier index columns limit the search to a small number of rows. Use the new OP_SeekScan opcode which does scanning of the relevant range of the index but gives up and falls back to doing a seek if the number of rows scanned grows to large, in order to guard against pathological cases where the estimated number of rows to be scanned is far too small. (check-in: f07ac3fb38 user: drh tags: branch-3.28) | |
|
2020-09-01
| ||
| 02:02 | Improvements to the IN-early-out optimization so that it works more efficiently when there are two or more indexed IN clauses on a single table. (check-in: 49b7631e86 user: drh tags: branch-3.28) | |
|
2020-08-31
| ||
| 19:19 | An attempt to improve the performance of the IN-early-out optimization (see check-in [09fffbdf9f2f6ce3]) by avoiding unnecessary calls to the b-tree search algorithm in OP_IfNoHope when the index key is at hand and the same answer can be obtained by doing a quick key comparison. <b>Update:</b> Experiment did not work out. (Closed-Leaf check-in: 8301da31d0 user: drh tags: branch-3.28-in-early-out-fail) | |
|
2020-08-17
| ||
| 21:03 | When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks. (check-in: 0ecda43371 user: dan tags: branch-3.28) | |
|
2020-05-06
| ||
| 18:46 | Provide the SQLITE_DEFAULT_LEGACY_ALTER_TABLE compile-time option. (check-in: b2325a6e1c user: drh tags: branch-3.28) | |
|
2020-04-04
| ||
| 00:29 | In the push-down optimization, do not substitute columns that have previously been identified as being constant by the propagate-constants optimization. Fix for ticket [51166be0159fd2ce]. Also, avoid factoring out constant expressions on the LHS of an IN(...) operator, as the IN(...) operation may affect the affinity of these values. Fix for [fd1bda016d1]. (Leaf check-in: 43612157f8 user: drh tags: branch-3.31) | |
|
2020-04-03
| ||
| 20:14 | Restore an #if block inadvertently removed via check-in [9c77bfe41e]. (check-in: bf6bcfc16e user: mistachkin tags: branch-3.31) | |
| 13:39 | Do not suppress errors when resolving references in an ORDER BY clause belonging to a compound SELECT within a view or trigger within ALTER TABLE. Fix for ticket [a10a14e9b4ba2]. Also, in the event of a semantic error in an aggregate query, early-out the resetAccumulator() function to prevent problems due to incomplete or incorrect initialization of the AggInfo object. Fix for ticket [af4556bb5c285c08]. (check-in: b64674919f user: drh tags: branch-3.31) | |
| 13:29 | Fix a case when a pointer might be used after being freed in the ALTER TABLE code. Fix for [4722bdab08cb1]. (check-in: 52f800fa93 user: drh tags: branch-3.31) | |
|

| 19:55 | Fix problem in test script concreport.test. (check-in: 32d1b7210a user: dan tags: begin-concurrent-report) | |
| 19:23 | Prevent the read-only expressions held in the schema from being passed down into code generating subroutines where they might be changed. Pass a copy of the expression instead. (check-in: 2b750b0f74 user: drh tags: branch-3.31) | |
|
2020-03-09
| ||
| 21:00 | Report on pages, as well as keys, read and written by BEGIN CONCURRENT transactions. (check-in: b661ccc88f user: dan tags: begin-concurrent-report) | |

|
2020-03-06
| ||
| 20:51 | Enhancement to log logical writes as well as reads. (check-in: 1c1f180eb6 user: dan tags: begin-concurrent-report) | |
|

| 19:00 | Merge trunk change [895bd20b29] into this branch. (Actually check-in date was 2020-05-18) (check-in: 507f972e91 user: dan tags: reuse-schema) | |
| 18:04 | Report an error if the main, or any other, database encoding is modified by an external process (perhaps using the backup API) after the db has been opened. (check-in: 895bd20b29 user: dan tags: trunk) | |
| 16:30 | Merge trunk enhancements into the reuse-schema branch. (Actual check-in date is 2020-05-18) (check-in: 9d068e1ef0 user: drh tags: reuse-schema) | |
| 16:13 | Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc]. (check-in: 4a5851893c user: drh tags: trunk) | |
| 14:19 | When printing the OP_CollSeq opcode for EXPLAIN listings, include the text encoding with the name of the collating sequence. (check-in: eb5c1b77d1 user: drh tags: trunk) | |

| 20:48 | Fix a false-positive in the debugging logic that attempts to detect the use of uninitialized registers inside triggers. Ticket [c4c56482ced89d90] (check-in: 0463576b5d user: drh tags: trunk) | |
| 20:04 | Remove an invalid assert() on the debugging logic that checks to ensure that register values are not used after they go stale. Ticket [d165ad781b39d574]. (check-in: bd94d7d052 user: drh tags: trunk) | |
| 01:16 | Improved detection of corruption in the interior nodes of a segment btree in FTS3/4. (check-in: cc99447ac9 user: drh tags: trunk) | |

|
2020-02-29
| ||
| 17:19 | Fix a problem with window functions occuring within sub-selects that are part of an OR term in a WHERE clause of the outer SELECT. (check-in: 1e174ed0d2 user: dan tags: trunk) | |
| 15:53 | In the CLI, add the ".oom" command for debugging builds. (check-in: 9c3136a722 user: drh tags: trunk) | |
|
2020-02-28
| ||
| 16:04 | The RTREE extension behaves as if data columns have type REAL, so we should actually declare them as REAL so that automatic indexes handle them correctly. Ticket [e63b4d1a65546532] (check-in: 85a9b6a92f user: drh tags: trunk) | |
|
2020-02-27
| ||
| 17:16 | In sqlite3changeset_apply(), ensure that DELETE and UPDATE changes are always executed on main database tables, not similarly named temp tables, as documented. INSERT statements are already being handled correctly. (check-in: f71a13d072 user: dan tags: trunk) | |
| 16:21 | Fix harmless compiler warnings from MSVC. (check-in: 951b39ca74 user: drh tags: trunk) | |

| 15:07 | Optimization for "SELECT min(x) FROM tbl" where "x" is indexed and NOT NULL. This also allows similar queries on NOT NULL virtual table columns to be optimized. (check-in: 5972677793 user: dan tags: trunk) | |
| 13:54 | Extra zero terminators on the end of the blank filename returned by sqlite3PagerFilename() for an in-memory database. This helps the result work better with sqlite3_filename_journal() and similar functions. (check-in: 63e533d28e user: drh tags: trunk) | |
| 12:33 | Backport the change that allows the filename passed into the xFullPathname to be used as an argument to sqlite3_uri_parameter(). (check-in: 9c77bfe41e user: drh tags: branch-3.31) | |
| 11:32 | Ensure that the filename passed into the xFullPathname method of the VFS is acceptable as an argument to sqlite3_uri_parameter(). The interface spec does not guarantee this, but it has been so historically and some applications have come to depends on it. (check-in: bfb09371d4 user: drh tags: trunk) | |
|
2020-02-25
| ||
| 20:05 | Update the fuzzcheck test module so that it avoids inserting text values that contain embedded NULs in the XSQL table. Fix some legacy entries in the test/fuzzdata8.db that had embedded NULs. Add in new dbsqlfuzz cases that have accumulated over on the dbsqlfuzz project for a while. (check-in: 47d4240c4a user: drh tags: trunk) | |

2020-02-24
| ||
| 17:05 | If STAT4 determines that a WHERE clause term that is not used by an index has very high probability of being true, then do not use that term to reduce the estimated output row count. (check-in: 40739c793b user: drh tags: trunk) | |
| 16:46 | Rework this changes so that instead of setting the WhereTerm.truthProb when a term is seen to be of low selectivity, it merely sets a new flag (the TERM_HIGHTRUTH flag) which causes whereLoopOutputAdjust() to ignore that term. (Closed-Leaf check-in: 4558163b6a user: drh tags: stat4-truthprob) | |
| 13:35 | Disable the new analyzeG.test module if not building with STAT4. (check-in: 4a9d300576 user: drh tags: stat4-truthprob) | |

|
2020-02-22
| ||
| 18:27 | Do not activate the truthProb adjustment mechanism if the truth probability is less than the heuristic value, as there could be correlations unknown to stat4. Also add additional tracing output to make truthProb adjustments more visible. (check-in: c535fea147 user: drh tags: stat4-truthprob) | |
| 17:32 | Add new test file analyzeG.test, containing a test for the change on this branch. (check-in: 243ab1852a user: dan tags: stat4-truthprob) | |
| 16:58 | When stat4 information is available, try to use it to improve the truth probability of WHERE clause terms that do not participate in the index. (check-in: 1babd6ec5d user: drh tags: stat4-truthprob) | |
| 13:01 | In the OP_Column opcode, if the cursor is marked NullRow (due to being the right table of a LEFT JOIN that does not match) and the cursor is the table cursor for an OR-optimization with a covering index, then do not substitute the covering index cursor, since the covering index cursor does not have the NullRow flag set. Ticket [aa4378693018aa99] (check-in: f02030b340 user: drh tags: trunk) | |
