| 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 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 [ticket baa5bb76c35a124c]. (check-in: 0163b697dd user: drh tags: branch-3.28) | |
|
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) | |
|
2022-08-09
| ||
| 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) | |
|
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. Update: 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) | |
|
2020-01-17
| ||
| 15:33 | More restrictions on changes to shadow tables when in defensive mode. (check-in: b302b260ca user: drh tags: branch-3.28) | |
| 15:24 | Validate the type, name, and tbl_name fields of the sqlite_master table when loading the schema, unless writable_schema is engaged. (check-in: 3d13fbf248 user: drh tags: branch-3.28) | |
| 14:56 | Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f16 user: drh tags: branch-3.28) | |
| 14:30 | Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. (check-in: be4269c624 user: drh tags: branch-3.28) | |
|
2019-12-19
| ||
| 03:14 | More restrictions on changes to shadow tables when in defensive mode. (Leaf check-in: 4146c629c6 user: drh tags: branch-3.30) | |
|
2019-11-16
| ||
| 18:36 | Do not allow shadow tables to be dropped in defensive mode. (check-in: 0a988ce340 user: drh tags: apple-osx) | |
| 18:30 | Modify three test cases so that they work even with unusual versions of the library printf(). (check-in: c25289075a user: drh tags: apple-osx) | |
|
2019-11-15
| ||
| 02:52 | Merge the version 3.30.1 changes into the apple-osx branch. (check-in: 2c8af35206 user: drh tags: apple-osx) | |
|
2019-11-14
| ||
| 23:08 | Backport support for the sqlite3_hard_heap_limit64() interface and the hard_heap_limit pragma to the 3.30 branch. (check-in: ba27012d43 user: drh tags: branch-3.30) | |
| 15:10 | Minor documentation enhancements. No changes to code. (check-in: 6153f3aada user: drh tags: hard-heap-limit) | |
|
2019-10-18
| ||
| 22:54 | Use an allocation count and freelist instead of a membership bitfield in the mini lookaside allocator (Leaf check-in: 9496b4d378 user: numist tags: 2-size-lookaside) | |
| 17:42 | Get generated columns working for WITHOUT ROWID tables. (check-in: 9f409649ec user: drh tags: generated-columns) | |
| 12:52 | Claw back some performance from the sqlite3ExprGetColumnOfTable() routine. (check-in: e8426acb94 user: drh tags: generated-columns) | |

| 10:05 | Get indexes working on virtual columns. (check-in: 450c48766c user: drh tags: generated-columns) | |
| 02:19 | STORED columns can now reference other STORED columns, in any order, as long as there are not loops. (check-in: 0d236698e6 user: drh tags: generated-columns) | |
|
2019-10-17
| ||
| 18:35 | In the Table object, change the nVCol field to nNVCol - the number of non-virtual columns, as that is the quantity that we need most. (check-in: 4ad66af04a user: drh tags: generated-columns) | |
| 18:07 | Bug fix with INSERT using an explicit column list on a table with a non-final STORED column. (check-in: 61b4459ae6 user: drh tags: generated-columns) | |
| 17:54 | Some (but not all) INSERT and UPDATE statements now work for STORED columns. (check-in: fe7517bf4d user: drh tags: generated-columns) | |
| 16:16 | Fix the xfer optimization for generated columns, so that VACUUM works again. (check-in: 8f67b89b04 user: drh tags: generated-columns) | |

| 13:15 | Fix the table_info and table_xinfo pragmas so that they work with virtual columns. Table_info omits virtual columns. Table_xinfo gives them a "hidden" flag of 2, and 3 for STORED columns. (check-in: 069351b85f user: drh tags: generated-columns) | |
|
2019-10-16
| ||
| 22:01 | INSERT with named columns for a table with generated columns. (check-in: 64db39f92d user: drh tags: generated-columns) | |
| 20:05 | ALTER TABLE is able to add a VIRTUAL column. (check-in: 120c6b78cb user: drh tags: generated-columns) | |
| 19:31 | Simple INSERT and SELECT operations working with VIRTUAL columns. (check-in: 7f9f90b1b8 user: drh tags: generated-columns) | |
| 14:56 | If an AFTER DELETE trigger fires when a conflict row is deleted by REPLACE conflict resolution, make sure the conflict really has been resolved and that the trigger did not recreate the row before continuing. Ticket [a8a4847a2d96f5de] (check-in: eea1e7aa57 user: drh tags: trunk) | |
| 12:18 | Initial experimental code for generated column support. Non-functional. (check-in: 11d472c1df user: drh tags: generated-columns) | |
|
2019-10-15
| ||
| 19:01 | Formatting change on a multi-line conditional, for improved clarity. No logic changes. (check-in: 7248e34765 user: drh tags: trunk) | |
|
2019-10-14
| ||
| 20:32 | Futher improvements to the IN operator for row-values on virtual tables. (check-in: bc751fb64d user: drh tags: trunk) | |

|
2019-10-12
| ||
| 23:38 | When Select-Trace is enabled (in debugging builds only) do not show the result of Window function tree rewrites if there are no window functions. (check-in: d1acf72ae1 user: drh tags: trunk) | |
|
2019-10-11
| ||
| 18:55 | Update the zipfile extension to use deflateBound(), instead of compressBound(), to learn the maximum possible size of a deflate()d buffer. (check-in: f5ee30426e user: dan tags: trunk) | |
| 17:14 | Futher improvements to LEFT JOIN strength reduction. (check-in: 8a39167bd2 user: drh tags: trunk) | |
| 16:01 | Improvements to the LEFT JOIN strength reduction optimization. (check-in: 548082dfab user: drh tags: trunk) | |
| 15:33 | Ensure fts3/4 prefix indexes are flushed to disk before an 'optimize' command. Fix for [745f1abc]. (check-in: 4ed905b188 user: dan tags: trunk) | |
| 14:27 | Fix the fts3/4 integrity-check command so that it works with "ORDER=DESC" tables. Fix for [8a6fa2bb]. (check-in: 5863546df9 user: dan tags: trunk) | |
| 14:25 | Increase the version number to 3.31.0 for the next release cycle. (check-in: ffd4c30620 user: drh tags: trunk) | |
| 14:21 | Faster response to sqlite3_interrupt() in the OP_IntegrityCk and OP_Count opcodes. (check-in: bf875dc599 user: drh tags: trunk) | |

| 23:58 | Update the autoconf makefile for MSVC. (check-in: 9455643eec user: mistachkin tags: trunk) | |
| 23:58 | Fix harmless compiler warning seen with MSVC. (check-in: 73a8211473 user: mistachkin tags: trunk) | |
| 20:19 | Version 3.30.1 (check-in: 18db032d05 user: drh tags: release, version-3.30.1, branch-3.30) | |
| 17:09 | Prevent SQLite from assuming that if ((? IS NOT NULL) IS NOT NULL) is true, ? may not be NULL. Fix for [c31034044bb72c89]. (check-in: 7833feecfe user: dan tags: trunk) | |
| 16:41 | Fix a problem in the fts3 integrity-check routine causing it to report as corrupt tables that contain values with embedded 0x00 bytes. Ticket [278ac142625e3dcd] (check-in: 629e20c988 user: dan tags: trunk) | |

| 15:26 | Disallow fts5 page sizes greater than 65536 bytes - as there are 16-bit offsets used in the page header. Fix for [81a7f7b9]. (check-in: 75775c5ab4 user: dan tags: trunk) | |
| 15:08 | Remove the "fastfuzztest" makefile target. Use only "fuzztest". (check-in: e17571c789 user: drh tags: trunk) | |
| 15:03 | New test cases added to test/fuzzdata8.db. (check-in: b68d21e93a user: drh tags: trunk) | |

| 13:52 | Use the "fuzztest" target in place of "fastfuzztest". (Closed-Leaf check-in: 7129e468fd user: drh tags: makefile-cleanup) | |
| 13:12 | Remove the obsolete "fastfuzztest" target from the makefiles. (check-in: 3d44f1ee0f user: drh tags: makefile-cleanup) | |
| 01:19 | Save CPU cycles in sqlite3Prepare() by, among other things, shifting the EXPLAIN column label logic over to sqlite3VdbeMakeReady(). (check-in: 1ca5ef8450 user: drh tags: trunk) | |
|
2019-10-08
| ||
| 19:45 | Store 64-bit offset values in osinst log files. (Leaf check-in: 74d975c69a user: dan tags: osinst) | |
| 13:34 | Fix problems with using the fts5 'rebuild' command inside a transaction that contains other updates of the same table. Fix for [e258f008]. (check-in: 238e083571 user: dan tags: trunk) | |
|
2019-10-07
| ||
| 20:36 | Disallow page-sizes smaller than 32 bytes in fts5. Also ensure the fts5 integrity-check works even when "PRAGMA reverse_unordered_selects" is true. Fix for [265e935b26]. (check-in: 8ab0aebdb3 user: dan tags: trunk) | |
| 20:33 | Omit a pointless memory allocation in vdbeSorterSort(). (check-in: 5d76dbc5b0 user: drh tags: trunk) | |
| 18:43 | Fix a problem with running ALTER TABLE ADD COLUMN statements within a transaction that writes to one or more virtual tables. Fix for [8fe768e9]. (check-in: 31e85fbbc4 user: dan tags: trunk) | |

|
2019-10-05
| ||
| 19:53 | Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis. This check-in gives the speed benefit but not the reduction in code size. (check-in: 0b73a09270 user: drh tags: trunk) | |
| 19:37 | Fix a problem in Makefile.msc on this branch. (check-in: ed3499a1a5 user: dan tags: osinst) | |
