| ||
| 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) | |
|
2023-11-29
| ||
| 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) | |
|
2019-07-18
| ||
| 20:55 | Fix a problem where self-joins on views that are aggregate queries may return the wrong result. Cherrypick of [74ef97bf51dd531a]. (check-in: 2f0a564f user: mistachkin tags: branch-3.28) | |
|
2019-06-03
| ||
| 15:10 | Fix harmless compiler warning in lemon. (check-in: 3a052429 user: mistachkin tags: branch-3.28) | |
| 13:53 | Fix the count-of-view optimization so that it is (correctly) disabled for a query that includes a WHERE clause or a GROUP BY clause. Cherrypick of [05897ca48a40c6771]. (check-in: 583e5a0a user: mistachkin tags: branch-3.28) | |
|
2019-05-04
| ||
| 01:41 | In the sqlite3_value or Mem object, make the MEM_IntReal type completely independent from MEM_Int and MEM_Real. This helps avoid problems when inserting non-float values into a "REAL" column. (check-in: 5a8a23ee user: drh tags: trunk) | |
| 01:29 | New testcase macros to ensure that MEM_IntReal is fully tested. (Closed-Leaf check-in: 8b8ef445 user: drh tags: int-real) | |
|
2019-05-03
| ||
| 21:17 | Add the SQLITE_TESTCTRL_RESULT_INTREAL test-control and use it to create the intreal() SQL function in testfixture. Write a few simple tests to prove this all works. TH3 will hold most of the INTREAL tests, probably. (check-in: c9838731 user: drh tags: int-real) | |
| 19:34 | Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. (check-in: 3a16ddf9 user: drh tags: trunk) | |
| 18:50 | Fix a memory-leak/segfault caused by using OP_OpenDup and OP_OpenEphemeral on the same VM cursor. (check-in: a9b90aa1 user: dan tags: trunk) | |
| 17:19 | Fix a problem where self-joins on views that are aggregate queries may return the wrong result. (check-in: 74ef97bf user: dan tags: trunk) | |
| 17:08 | Improved comments on the elements of the array constant used to implement the sqlite3_value_type() interface. (check-in: f73a7de7 user: drh tags: int-real) | |
| 02:41 | Fix the ".open --hexdb" command in the CLI so that it works even with terminal input. (check-in: 9b5d9434 user: drh tags: trunk) | |
|
2019-05-02
| ||
| 21:36 | Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. (check-in: dba836e3 user: drh tags: int-real) | |
| 17:45 | Ensure that the typeof() function always returns SQLITE_FLOAT for floating point values even when the value is stored as an integer to save space. (check-in: 48889530 user: drh tags: trunk) | |
| 17:06 | Add options to wapptest.tcl similar to those supported by releasetest.tcl. Also add the -noui switch, for running without wapp altogether. (check-in: 005a1694 user: dan tags: trunk) | |
| 15:56 | Earlier detection of a database corruption case in balance_nonroot(), to prevent a possible use of an uninitialized variable. (check-in: c509d8a8 user: drh tags: trunk) | |
| 14:15 | Merge enhancements from trunk (check-in: 3a4751a9 user: drh tags: hard-heap-limit) | |
| 01:41 | The "LIKE Optimization" (which converts a LIKE into a BETWEEN operator that is able to use an index) does not work and cannot be used if the collating sequence of the column is not TEXT and if the pattern starts with a "+" sign. This is another case of ticket [c94369cae9b561b1f996d005]. The new test case was discovered by Manuel Rigger. (check-in: b043a54c user: drh tags: trunk) | |
| 00:52 | Fix an issue (discovered by OSSFuzz) in the enhanced OP_Concat operator from check-in [713caa382cf7dd] earlier today. (check-in: 3e897702 user: drh tags: trunk) | |
|
2019-05-01
| ||
| 19:01 | Add a test case for ticket [ae0f637bddc5290b44669e066a]. (check-in: ece48169 user: drh tags: trunk) | |
| 18:59 | When values have real affinity and are converted into strings for CHECK constraints or index expressions, do the conversions into a real-number format even if the values are stored as integers for efficiency. This appears to fix ticket [ae0f637bddc5290b446]. (check-in: 5997d075 user: drh tags: trunk) | |
| 17:36 | Fix an incompatibility with -DSQLITE_OMIT_LOAD_EXTENSION=1 in dbdata.test. (check-in: a77cd85b user: dan tags: trunk) | |
| 17:32 | Fix a case in wapptest.tcl where a failed test might report 0 errors. (check-in: 2be1ed70 user: dan tags: trunk) | |
| 15:32 | Avoid unwelcomed side effects on the input operands in the OP_Concat operator. Fix for ticket [3be1295b264be2fac49b681] (check-in: 713caa38 user: drh tags: trunk) | |
| 15:25 | Update wapptest.tcl so that it deletes extra files if the "Keep files:" checkbox is clear. Set it by default. (check-in: 09623cc4 user: dan tags: trunk) | |
| 14:41 | In "PRAGMA vdbe_trace" output, show the results of OP_Affinity opcodes. (check-in: 56604bb6 user: drh tags: trunk) | |
| 08:48 | Fix an incompatibility with auto-vacuum mode in new test script recover.test. (check-in: 36dd5b08 user: dan tags: trunk) | |
|
2019-04-30
| ||
| 20:43 | Update wapptest.tcl to use a simpler slave script. And to leave scripts wapptest_configure.sh and wapptest_make.sh in each test directory. (check-in: 07e527d7 user: dan tags: trunk) | |
| 15:36 | Fix a problem allowing a Table object to be deleted from within a call to the xDestroy method of the associated virtual table, causing a use-after-free error. (check-in: 1dbbb010 user: dan tags: trunk) | |
| 14:26 | Fix an error message in the Lemon parser generator. (check-in: b6d7d42b user: drh tags: trunk) | |
| 11:54 | Small performance increase and size reduction in the implementation of the LIKE and GLOB operators. (check-in: f97626f9 user: drh tags: trunk) | |
| 01:08 | Slightly smaller and faster implementation of the OP_MakeRecord opcode. (check-in: 3bdce7ef user: drh tags: trunk) | |
|
2019-04-29
| ||
| 16:44 | Changes to oserror.test so that it works even on systems that allow an unusually large number of file descriptors. (check-in: a27b0b88 user: drh tags: trunk) | |
| 13:48 | Do not de-duplicate columns index columns associated with a WITHOUT ROWID table if the columns have different collating sequences. This is the fix for ticket [3182d3879020ef3b2]. There is one test case added, but most of the tests are done in TH3. (check-in: 1b1dd4d4 user: drh tags: trunk) | |
| 13:30 | Improved header comment and precondition checking for the new isDupColumn() function. (Closed-Leaf check-in: 740d5ff6 user: drh tags: tkt-3182d38790) | |
| 11:41 | Fix a buffer overwrite in shell.c.in (part of the new .recover code). (check-in: 92facbc7 user: dan tags: trunk) | |
| 11:27 | Fix a stack overflow that could occur when renaming a table that has a trigger containing a window function invocation that itself contains a specific syntax error. (check-in: c621fc66 user: dan tags: trunk) | |
|
2019-04-28
| ||
| 19:27 | Take collating sequence into account when removing redundant columns from indexes on WITHOUT ROWID tables. This is the first proof-of-concept fix for ticket [3182d3879020ef3]. More testing needed. (check-in: b34fa5bf user: drh tags: tkt-3182d38790) | |
|
2019-04-27

| 20:06 | Merge latest trunk changes into this branch. (check-in: 1da302d8 user: dan tags: dbdata) | |
| 19:23 | Unless the "--freelist-corrupt" option is specified, do not have the .recover command attempt to recover data from pages that are on the database free-list. (check-in: 8d2f52bb user: dan tags: dbdata) | |
| 18:15 | Add the sqlite3_hard_heap_limit64() interface and the corresponding "PRAGMA hard_heap_limit=N" command. (check-in: b0ccef61 user: drh tags: hard-heap-limit) | |
| 16:20 | Fix a bug preventing .recover from working on databases where the final page of the db is corrupt. (check-in: 959bbd11 user: dan tags: dbdata) | |
|
2019-04-24

| 15:30 | Changes to the --hexdb decoder option in the shell (and also in the TCL test code) so that it works on systems where sscanf() does not recognize "%hhx" as wanting to delivery results into a character-size variable. (check-in: 4258e42d user: drh tags: trunk) | |
| 15:21 | Minor simplification of NULL value handling for STAT4. Cherrypick of [69bad9257f8db6a2] from trunk. (check-in: 442c177d user: mistachkin tags: branch-3.28) | |

Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer).

| 02:37 | Simplification to the logic that detects misuse of the application-defined function creation interfaces. (check-in: 8f21d778 user: drh tags: trunk) | |
| 02:02 | During WITHOUT ROWID table creation, if the sqlite3CreateTable() call fails due to an authorizer denying the INSERT into the sqlite_master table, then detect this fact and abort the CREATE TABLE early, to avoid an assertion fault. (check-in: 164b1641 user: drh tags: trunk) | |

| 01:02 | Identify specific FuncDef objects for window functions using the pointer to the function name (FuncDef.zName) rather than the pointer to the xStep method.

| 23:23 | When the query planner has the opportunity to use an IN operater constraint on a term of an index other than the left-most term, use the estimated number of elements on the right-hand side of the IN operator to determine if makes sense to use the IN operator with index lookups, or to just do a scan over the range of the table identified by the index terms to the left. Only do this if sqlite_stat1 measurements are available as otherwise the performance estimates will not be accurate enough to discern the best plan. Bias the decision slightly in favor of using index lookups on each element of the IN operator. (check-in: 2cbbabdf user: drh tags: trunk) | |
| 21:21 | Only choose to scan an IN operator rather than use an index if we have real STAT1 data to suggest it is advantageous. (Closed-Leaf check-in: 30e87466 user: drh tags: in-scan-vs-index) | |

| 18:22 | Consider doing a partial table scan to fulfill an IN operator rather than using an index. Try to pick the plan with the lowest cost. (check-in: 1fa40a78 user: drh tags: in-scan-vs-index) | |

| 18:13 | The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value.
