|
2024-06-07
| ||
| 00:20 | Allow the query planner access to the argument of LIMIT even if that argument is a bound parameter. (check-in: 148d505c user: drh tags: branch-3.28) | |
|
2024-06-06
| ||
| 16:06 | Better optimize queries that use parameters in the LIMIT clause. (Closed-Leaf check-in: b44f2676 user: drh tags: branch-3.28-var-in-limit) | |
|
2024-04-02
| ||
| 18:48 | Fix typos in comments. Provided ".wheretrace" debugging output for the interstage heuristic module. Do omit automatic index loops in the interstage heuristic. (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) | |
|
2023-11-29
| ||
| 16:26 | Fix a duplicate assert() caused by the second cherrypick in the previous check-in. (check-in: f10d4fc4 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: f9c6e6a7 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. Also fix an incorrect ".selecttrace" code block. (check-in: 83a7f13e 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: ad6ac5d3 user: drh tags: branch-3.28) | |
| 19:04 | Back-port omit-unused-subquery-column enhancements into the 3.28 branch. (check-in: 57a4e91f 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: 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) | |
| 01:21 | Update test cases so that they work with TCL 8.7 and later. (check-in: e9b762de 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: a7cbf308 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) | |
|
2022-09-01
| ||
| 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) | |
|
2022-08-10
| ||
| 17:03 | Merge the branch-3.28a fixes into branch-3.28. (check-in: ba6bf331 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: 68d86f2b user: drh tags: branch-3.28) | |
|
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: d2e67220 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: 9e001b63 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: 263293f1 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: c144d640 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: ec37744c 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: 9a1cdf7e 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: f07ac3fb 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: 49b7631e 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: 8301da31 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: 0ecda433 user: dan tags: branch-3.28) | |
|
2020-05-06
| ||
| 18:46 | Provide the SQLITE_DEFAULT_LEGACY_ALTER_TABLE compile-time option. (check-in: b2325a6e user: drh tags: branch-3.28) | |
|
2020-01-17
| ||
| 15:33 | More restrictions on changes to shadow tables when in defensive mode. (check-in: b302b260 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: 3d13fbf2 user: drh tags: branch-3.28) | |
| 14:56 | Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f 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: be4269c6 user: drh tags: branch-3.28) | |
| 14:18 | Import all FTS3/4 enhancements and fixes that exist on the latest trunk (3.31.0-beta) that do not require extensive change to the SQLite core into the 3.22 branch. Basically, the 3.31.0 FTS3 sources are copied into 3.22.0, with minor changes to work around core enhancements that are not available in 3.22.0. (Leaf check-in: cbcbb1e5 user: drh tags: branch-3.22) | |
|
2019-09-03
| ||
| 18:36 | Fix a buffer overread that could occur when running fts5 prefix queries inside a transaction. (check-in: 68b89838 user: drh tags: branch-3.22) | |
| 18:04 | Disable the undocumented rtreenode() SQL function that is only used for testing, except when doing a build that is specifically intended for testing. (check-in: 8452fd54 user: drh tags: branch-3.22) | |
|
2019-08-20
| ||
| 20:09 | Further tests for the special null-handling on this branch. (check-in: 0dbbb51f user: dan tags: nulls-last) | |
| 17:51 | Add tests for sort-by-index cases that use IN() and non-default NULL handling. (check-in: 09d660ec user: dan tags: nulls-last) | |
| 15:47 | Do not pass ORDER BY clauses with non-standard NULL handling to virtual table implementations. (check-in: a9a82ee8 user: dan tags: nulls-last) | |
|
2019-08-19
| ||
| 20:35 | Omit the "_except" term from the name of the new interface. (Closed-Leaf check-in: e5ba47c2 user: drh tags: sqlite3_drop_modules_except) | |
| 19:59 | Fix problems with window frames that use ORDER BY ... NULLS LAST etc. (check-in: 75d665a4 user: dan tags: nulls-last) | |
| 17:26 | Prevent NULLS FIRST/LAST from being used in CREATE INDEX and other statements. (check-in: bb9767a2 user: dan tags: nulls-last) | |
|
2019-08-17
| ||
| 19:45 | The experimental sqlite3_drop_modules_except() interface. (check-in: 0851db4d user: drh tags: sqlite3_drop_modules_except) | |
| 19:31 | Fix the new ability to unregister virtual table modules so that it works for the automatic PRAGMA virtual tables. (check-in: 5d6f4dfe user: drh tags: trunk) | |
| 19:13 | When populating an ephemeral b-tree for the RHS of an IN(...) clause, avoid applying an affinity to a value that may be used later on for some other purpose. Fix for [c7a117190]. (check-in: 43e8b143 user: dan tags: trunk) | |
| 18:16 | Add tests to ensure that this branch really does fix ticket [f8a7060ece]. (check-in: f8920664 user: dan tags: nulls-last) | |
| 17:55 | Fix problem with DESC indexes on this branch. (check-in: b49df1fe user: dan tags: nulls-last) | |
| 17:07 | Ensure the functions that appear to be constant are not factored out of expression that originate on the right-hand side of a LEFT JOIN. Ticket [6710d2f7a13a2997] (check-in: 500c9152 user: drh tags: trunk) | |
| 15:47 | Merge trunk changes into this branch. (check-in: db1e6080 user: dan tags: nulls-last) | |
| 15:27 | Activatate introspection pragmas by default. The new option SQLITE_OMIT_INTROSPECTION_PRAGMAS must be provided to keep them out. (check-in: 9c4bca64 user: drh tags: trunk) | |
| 00:53 | The SQLITE_DIRECTONLY flag, when added to sqlite3_create_function() prevents the function from being used inside a trigger or view. (check-in: de767376 user: drh tags: trunk) | |
|
2019-08-16
| ||
| 22:58 | Add the ability to unregister a virtual table module by invoking sqlite3_create_module() with a NULL sqlite3_module pointer. (check-in: 31e34fa3 user: drh tags: trunk) | |
| 21:07 | Add support for using indexes for some ORDER BY clauses that use non-default NULL handling. Still some problems on this branch. (check-in: 81069d71 user: dan tags: nulls-last) | |
|
2019-08-15
| ||
| 23:11 | Fix harmless compiler warnings in the TCL interface. (check-in: f17e7229 user: drh tags: trunk) | |
| 21:27 | Add the SQLITE_DBCONFIG_ENABLE_VIEW option, together with a "db config" command in the TCL interface that can access that option as well as all the other sqlite3_db_config() boolean options. (check-in: 61b4bccd user: drh tags: trunk) | |
| 20:04 | Provide the SQLITE_DIRECTONLY flag for app-defined functions that prohibits the use of those functions within triggers or views. (Closed-Leaf check-in: fc745845 user: drh tags: directonly) | |
| 14:35 | Ensure that the optional "sz=N" parameter that can be manually added to the end of an sqlite_stat1 entry does not have an N value that is too small. Ticket [e4598ecbdd18bd82] (check-in: 98357d8c user: drh tags: trunk) | |
| 13:53 | Ensure that SQLite does not attempt to process incompatible window functions in a single scan. Fix for [256741a1]. (check-in: 4f5b2d93 user: dan tags: trunk) | |
| 13:46 | Avoid downgrading SQLITE_CORRUPT errors detected by the schema parser into SQLITE_NOMEM or SQLITE_ERROR errors. (check-in: b2e79f8f user: drh tags: trunk) | |
| 13:17 | Ensure that the cell overwrite optimization does not overwrite the header of the b-tree page. (check-in: 4cc5694c user: drh tags: trunk) | |
| 00:04 | Early detection out-of-bounds page numbers on the direct-overflow-read optimization gives consistent error messages regardless of whether or not the optimization is enabled. (check-in: b517a52f user: drh tags: trunk) | |
|
2019-08-14
| ||
| 15:17 | Always check for reads past the end of the file on the in-memory journal driver. This used to be an assert(). (check-in: 4d41ca7d user: drh tags: trunk) | |
|
2019-08-13
| ||
| 20:34 | Add some static to the 'regexp' extension. (check-in: a21d1dde user: mistachkin tags: trunk) | |
| 17:56 | Update test cases so that they work with ICU enabled. (check-in: 408144a1 user: dan tags: trunk) | |
| 17:27 | Update some corruption test cases to take [724f4df9c] into account. (check-in: 927cd7b4 user: dan tags: trunk) | |
| 15:22 | Merge latest trunk changes with this branch. (check-in: 5b4689d8 user: dan tags: reuse-schema) | |
| 15:11 | Fix a problem with RBU function sqlite3rbu_bp_progress() when used during an RBU vacuum. (check-in: 8c44b02f user: dan tags: trunk) | |
|
2019-08-12
| ||
| 18:26 | Make sure the btree cursor overflow cache is cleared when overwriting a cell in sqlite3BtreeInsert(). Ticket [3cf9bb227e9a5d32] (check-in: 7dae7b96 user: drh tags: trunk) | |
| 16:36 | Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. (check-in: 07babb0f user: dan tags: nulls-last) | |
| 16:25 | For the ".testctrl prng_seed" command in the CLI, if the argument is "random" then select a random integer seed and print the seed value on stdout. (check-in: 636ca447 user: drh tags: trunk) | |
| 15:37 | Fix the build for compilation using separate files rather than the amalgamation. (Leaf check-in: 1e0f4869 user: drh tags: sha3) | |
| 15:19 | Make the sha3 extension part of the amalgamation, enabled using SQLITE_ENABLE_SHA3. (check-in: a48a7b78 user: drh tags: sha3) | |
| 14:17 | Add a TESTCTRL that disables the verification of type, name, and tbl_name in the sqlite_master table. (check-in: 48d9b48a user: drh tags: trunk) | |
| 00:08 | Validate the type, name, and tbl_name fields of the sqlite_master table when loading the schema, unless writable_schema is engaged. (check-in: 724f4df9 user: drh tags: trunk) | |
|
2019-08-10
| ||
| 15:06 | Fix the sqliteExprImpliesExpr() routine so that it recognizes that "(NULL IS FALSE) IS FALSE" doe not imply "NULL NOT NULL". Ticket [9080b6227fabb466] (check-in: da01ba4f user: drh tags: trunk) | |
| 14:35 | Add extra test cases related to the previous commit. (check-in: 3c690b2b user: dan tags: trunk) | |
| 14:16 | Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. (check-in: 712e4771 user: drh tags: trunk) | |
|
2019-08-09
| ||
| 20:26 | Allow the RHS of a row-value IN operator to use a compound query with an ORDER BY clause. (check-in: eaf15d9b user: drh tags: trunk) | |
| 14:54 | In shared-schema mode, handle the case where a connection has created a virtual-table object, but is later assigned a different shared-schema object for which the virtual-table schema has not yet been initialized. (check-in: e30c7414 user: dan tags: reuse-schema) | |
| 01:59 | Modify signature of sqlite3VdbeChangeOpcode() to accept int instead of u32. (check-in: 68b7f2ac user: mistachkin tags: trunk) | |
| 01:11 | Fix more compiler warnings. (check-in: 1b85442b user: drh tags: trunk) | |
|
2019-08-08
| ||
| 19:40 | Fix harmless compiler warnings. (check-in: 1eef4dde user: drh tags: trunk) | |
| 19:19 | Remove support for SQLITE_ENABLE_STAT3. The sqlite_stat3 table is now ignored, if it exists. Run ANALYZE using STAT4 to get the equivalent functionality, which presumably everybody has been doing for a long time now. (check-in: f1cd234c user: drh tags: trunk) | |
| 18:49 | Fix a case of the Expr.affinity to Expr.affExpr refactor that was missed in the [a29f2a7d07beff64] check-in. (check-in: 83450d10 user: drh tags: trunk) | |
| 16:23 | More legacy STAT3 code removed. (Closed-Leaf check-in: 845d2f17 user: drh tags: omit-stat3) | |
| 15:47 | Fix spurious "no such table: x1" errors in shared-schema mode that could occur when a query that is a join across two or more databases needs to call the xConnect() methods of a virtual table. (check-in: edf45cd7 user: dan tags: reuse-schema) | |
| 15:24 | Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. (check-in: 1e17ea2f user: drh tags: omit-stat3) | |
| 11:44 | Fix a bug causing "no such table" and other similar sqlite3_prepare*() errors to return SQLITE_SCHEMA instead of SQLITE_ERROR in shared-schema mode when there is an attached database for which the schema has never been loaded. (check-in: 111e2c73 user: dan tags: reuse-schema) | |
| 01:39 | Remove a NEVER() that is reachable from a corrupt database. (check-in: 30e6ee27 user: drh tags: trunk) | |
|
2019-08-07
| ||
| 19:57 | Remove use of the affinity() function from view.test, as it is only available in SQLITE_DEBUG builds. (check-in: 7f2246a1 user: dan tags: trunk) | |
| 18:34 | Add "set TMP=%CD%" to the start of each msvc script output by releasetest_data.tcl. Otherwise, since binaries compiled with SQLITE_TEST all choose the same sequence of pseudo-random numbers, collisions between temp file names cause errors when running multiple tests in parallel. (check-in: f5d0436d user: dan tags: trunk) | |
| 17:45 | Eliminate some more cases of redundant sorting in window-function queries. (check-in: 8158d2ac user: dan tags: trunk) | |
| 13:25 | Do not make SQLITE_READ authorizer calls for tables without names, as all such tables will be internal-use-only tables for subqueries and whatnot. (check-in: 193c87fc user: drh tags: trunk) | |
|
2019-08-06
| ||
| 21:16 | Ensure that when the col in an operator like "val IN(col)" is a column of a view, its affinity is not used to coerce val. Fix for [0a5e2c1d]. (check-in: 17b3d221 user: dan tags: trunk) | |
| 20:55 | Improved reuse of file descriptors for which close() is delayed to prevent clearing of posix advisory locks. (check-in: 509c1ba2 user: drh tags: trunk) | |
| 20:26 | Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. (check-in: 846d2d2d user: drh tags: trunk) | |
| 18:40 | Add "PRAGMA foreign_keys=OFF;" to the start of the script output by ".recover", just as is done for ".dump". (check-in: bfc29e62 user: dan tags: trunk) | |
| 15:32 | Ensure that columns of views and sub-queries that are expressions with no affinity are comparied without any type conversions, as required in the documentation. Tickets [61c853857f40da49] and [d52a29a9e6bc55c5]. (check-in: 9c8c1092 user: drh tags: trunk) | |
| 15:18 | Performance optimization to the new affinity handling logic. (Closed-Leaf check-in: c9724e76 user: drh tags: pending) | |
| 15:02 | Add a multi-threaded test to threadtest3.c for the feature on this branch. (check-in: 62557fab user: dan tags: reuse-schema) | |
| 14:37 | Use 0x40 (ASCII '@') instead of 0x00 to mean "no affinity" so that columns with no affinity can appear in a zero-terminated string. Use the new SQLITE_AFF_NONE macro for this new magic number. (check-in: e8234f69 user: drh tags: pending) | |
| 11:45 | Add an assert() to the code on this branch. (check-in: fdd44bbb user: dan tags: reuse-schema) | |
|
2019-08-05
| ||
| 20:53 | Ensure that columns of views and sub-queries that are expressions with no affinity are not assigned BLOB affinity. This matches the documentation. Fix for [61c853857f40da49]. (On a branch because there are still subtle issues.) (check-in: e15a0977 user: dan tags: pending) | |
| 20:45 | Add test cases to this branch. (Closed-Leaf check-in: f37317d8 user: dan tags: tkt-61c853-A) | |
