| 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) | |
| 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: 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) | |
|
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) | |
|
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. 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) | |
|
2020-04-04
| ||
| 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) | |
|
2020-03-10
| ||
| 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) | |
|
2020-02-27
| ||
| 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) | |
|
2020-02-06
| ||
| 11:08 | Merge changes on 3.31 branch into reuse-schema. (check-in: 6dbb8cb0e3 user: dan tags: reuse-schema-3.31) | |
| 11:02 | Fix a 4 byte OOB read in test_multiplex.c. (check-in: 6279f69f0f user: dan tags: branch-3.31) | |
|
2020-02-01
| ||
| 14:29 | Fix a problem in sqlite3CodecQueryParameters() that was introduced by the query parameter encoding changes for the 3.31.1 release. (check-in: 1240ee4f6f user: drh tags: apple-osx) | |
| 13:30 | Fix a problem in sqlite3CodecQueryParameters() that was introduced by the query parameter encoding changes for the 3.31.1 release. (check-in: cc65ca5412 user: drh tags: branch-3.31) | |
| 00:08 | Merge version 3.31.1 (check-in: d250d085fa user: numist tags: apple-osx) | |
|
2020-01-29
| ||
| 12:37 | Modify a couple of FTS test cases so that they work on big-endian platforms. (check-in: b20503aaf5 user: drh tags: trunk) | |
|
2020-01-28
| ||
| 20:27 | Faster decoding of 32-bit variable-length integers in cases were we do not need to know the number of bytes in the encoding. (check-in: 59a31b16b5 user: drh tags: trunk) | |
| 20:09 | Small performance improvement to the key-comparision routine for strings. (check-in: 41454499a2 user: drh tags: trunk) | |
| 18:09 | Reinstate the optimization of converting "a IN (C)" into "a=C" but only if C is a constant. If the RHS is a table column, the complications of managing affinity and collations become too involved to mess with. (check-in: 8ac26a23d7 user: drh tags: trunk) | |
| 16:55 | Fix a 4 byte OOB read in test_multiplex.c. (check-in: 912148913c user: dan tags: trunk) | |
| 15:02 | Minor change for compatibility with the s390 architecture. (check-in: 04885763c4 user: drh tags: trunk) | |
|
2020-01-27
| ||
| 19:55 | Version 3.31.1 (check-in: 3bfa9cc97d user: drh tags: trunk, release, version-3.31.1) | |
| 17:09 | Update the version number to 3.31.1. (check-in: 6fb9a8fb85 user: drh tags: trunk) | |
| 14:40 | Revise the layout of filenames in the Pager object so that it is unchanged from prior versions. It turns out that some important 3rd-party software does questionable pointer manipulations on those filenames that depend on that legacy layout. Technically, this is a misuse of SQLite by the 3rd-party software, but we want to avoid unnecessary breakage. (check-in: 34ab760689 user: drh tags: trunk) | |
|
2020-01-23
| ||
| 15:00 | Fix typos in the sqlite3ext.h header file that prevent some newer APIs from being accessed from loadable extensions. (check-in: 14331989fc user: drh tags: trunk) | |
| 00:08 | Fix variable declaration issue seen with MSVC. (check-in: 8a6fe3066c user: mistachkin tags: trunk) | |
|

| 20:02 | Merge in version 3.31.0 (check-in: f418afa1bf user: drh tags: reuse-schema) | |
| 18:38 | Version 3.31.0 (check-in: f6affdd416 user: drh tags: trunk, release, version-3.31.0) | |
|
2020-01-21
| ||
| 21:01 | Begin adding instrumentation to record and report on the set of key-ranges a concurrent transaction reads from the database. (check-in: c39e3c14a9 user: dan tags: begin-concurrent-report) | |
| 16:31 | Update test file exclusive.test so that it works with the "journaltest" permutation. (check-in: 4daf94d833 user: dan tags: trunk) | |
| 16:23 | Fix a problem with using views in SQLITE_OMIT_VIRTUAL_TABLE builds. Also some test case fixes required for the same builds. (check-in: 934ee8bdb4 user: dan tags: trunk) | |
| 15:01 | Fix a case in fts3auto.test that fails for SQLITE_DISABLE_FTS4_DEFERRED builds. (check-in: d241055ead user: dan tags: trunk) | |
| 14:42 | Fix an assert() that could fail in SQLITE_MUTATION_TEST builds following an error in a query that uses CTEs. (check-in: c7e29458a7 user: dan tags: trunk) | |
| 13:40 | Fix a problem in the userauth extension causing it to occasionally set "PRAGMA count_changes" (and some others) to true. (check-in: 3a62f64222 user: dan tags: trunk) | |
| 12:29 | Fix the series.c and spellfix.c extensions to use SQLITE_VTAB_INNOCUOUS correctly. Fix the documentation on sqlite3_vtab_config() to take into account SQLITE_VTAB_INNOCUOUS and SQLITE_VTAB_DIRECTONLY. (check-in: 9265cb7f02 user: drh tags: trunk) | |
| 01:45 | Improvements to the autoconf TEA Makefile for MSVC. (check-in: cffcf12f03 user: mistachkin tags: trunk) | |
|
2020-01-20
| ||
| 15:32 | Merge recent fixes from trunk. (check-in: 9c920bbad3 user: drh tags: reuse-schema) | |
| 14:42 | In the fuzzcheck test program, reduce the default expression depth limit from 1000 to 500 to avoid stack-overflow problems when running stress tests using clang ASAN. (check-in: 63d886f4ce user: drh tags: trunk) | |
|
2020-01-19
| ||
| 20:37 | Enhancement to the CLI to allow the ".parameter init" command to work even if defensive mode is turned on. (check-in: 4d46255096 user: drh tags: trunk) | |
|
2020-01-18
| ||
| 23:52 | Documentation improvements. (check-in: 535afe1509 user: drh tags: trunk) | |
| 22:20 | In the TCL interface, add the ability to change the SQLITE_DBCONFIG_TRUSTED_SCHEMA setting using the "db config" method. (check-in: 1accfa8cf0 user: drh tags: trunk) | |
| 21:34 | Allow non-deterministic function in CHECK constraints. It turns out that PostgreSQL, MySQL, and SQLServer all allow this. We should not be the the exception. Ticket [830277d9db6c3ba1] (check-in: 8c8ce526ad user: drh tags: trunk) | |
| 19:58 | Fix a couple of test case issues on this branch. (check-in: 9830a44bc6 user: dan tags: reuse-schema) | |
| 19:46 | Do not use memcpy() of zero bytes when initializing a pager. This avoids a warning. (check-in: cca437788e user: drh tags: trunk) | |
| 19:07 | Disable a redundant test case that uses a very large stack, and hence is unable to run with -fsanitize=undefined,address. (check-in: 3c63f68e12 user: drh tags: trunk) | |
| 19:02 | Fix harmless compiler warning seen with MSVC. (check-in: cd0437ba5b user: mistachkin tags: trunk) | |
| 18:59 | Have this branch call sqlite3LockAndPrepare() instead of sqlite3Prepare() when parsing SQL for new schema objects in order to ensure that schemas are released as soon as possible. (check-in: 7a4ec57985 user: dan tags: reuse-schema) | |
| 14:50 | Add extra front margin to the fake empty filename returned by sqlite3PagerFilename() for an in-memory or TEMP database. (check-in: fee945671a user: drh tags: trunk) | |
| 13:53 | Fix the VDBE so that it correctly handles the sequence of operations OP_OpenEphemeral, OP_OpenDup, OP_OpenEphemeral, and OP_OpenDup in that order on the same cursor. (check-in: a1be6ee018 user: drh tags: trunk) | |
|
2020-01-17
| ||
| 23:27 | Fix a typo in a comment. No code changes. (check-in: 4363f69c3a user: drh tags: trunk) | |
| 21:12 | The compress() function should not be deterministic since the same input can have multiple possible compressed outputs. The uncompress() function, on the other hand, is deterministic. (check-in: 84f314902c user: drh tags: trunk) | |
| 19:14 | Fix #ifdefs so it compiles cleanly with all SQLITE_OMIT compile-time options. Update compile-time option testing. (check-in: 7584e4b649 user: drh tags: trunk) | |
| 16:47 | Improved rounding in the 'unixepoch' feature of the date and time functions. (check-in: c9abf1bd2d user: drh tags: trunk) | |
| 15:45 | Update test script instrfault.test to account for the fact that bound blob values cast to text values are now intepreted using the text encoding of the database, instead of always as utf-8. (check-in: 4d6cb28811 user: dan tags: trunk) | |
| 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) | |
| 11:18 | Fix a case in "fuzz.test" that could fail, as non-deterministic functions may no longer appear in CHECK constraints. (check-in: a370871e21 user: dan tags: trunk) | |
|
2020-01-16
| ||
| 17:53 | New testcase() macros in select.c, for coverage of the change from two check-ins ago. (check-in: 52206488f3 user: drh tags: trunk) | |
| 16:32 | Add the SQLITE_FCNTL_CKPT_DONE file-control for the use of custom VFSs. (check-in: 3cc39e5069 user: dan tags: trunk) | |
| 16:12 | Do not allow the constant-propagation optimization to apple to ON/USING clause terms as it does not help and it might cause downstream problems. (check-in: 1bc783da63 user: drh tags: trunk) | |
| 13:02 | Very small performance improvement by ensuring that the argument to sqlite3VdbeFreeCursor() is non-NULL. Hold for the next sprint. (Leaf check-in: f8801ffd94 user: drh tags: close-cursor-faster) | |
| 12:25 | Fix an SQL syntax error in the comment on the omit-left-join optimization. No changes to code. (check-in: 86b5e5a20e user: drh tags: trunk) | |
| 11:51 | Clean up the definitions of the TERM_ constants in the code generator. Formatting only - no logic changes. (check-in: af06f80a59 user: drh tags: trunk) | |
|
2020-01-15

| 20:30 | Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. (check-in: cdff3af7be user: drh tags: trunk) | |

| 23:04 | Completely remove the column cache logic, which has been a persistent source of bugs for many years. Due to recent enhancements to the performance of the OP_Column opcode, removing the column cache actually makes speed-check.sh run faster. Removing the column cache also saves about 1,800 bytes of code space. (check-in: 3f5f60cd75 user: drh tags: omit-column-cache) | |

This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time.

| 16:57 | Constant propagation is now restricted to just the WHERE clause. The mechanism is changed to take affinity and collation into account. This seems to give correct answers.
