|
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: 148d505ca0 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: b44f267671 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: 357d9513d2 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: 1f97086d62 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: 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) | |
|
2020-01-21
| ||
| 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) | |
|
2020-01-18
| ||
| 19:58 | Fix a couple of test case issues on this branch. (check-in: 9830a44bc6 user: dan tags: reuse-schema) | |
| 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) | |
|
2020-01-17
| ||
| 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
| ||
| 17:18 | Fix the assert_schema_state_ok() routine so that it correctly ignores ATTACH-ed database that failed to open due to an error. (check-in: 1194a42add user: drh tags: reuse-schema) | |
| 16:20 | Do not allow the "PRAGMA encoding" statement to change the database encoding if TEMP content exists, or content in any other attached database. Formerly, encoding changes were allowed if just the main database file was empty. Ticket [a08879a4a476eea9]. (check-in: 03b003c988 user: drh tags: trunk) | |
| 14:26 | Merge all recent enhancements and fixes from trunk. (check-in: f783917800 user: drh tags: reuse-schema) | |
| 14:21 | Merge in the latest trunk changes via the begin-concurrent-pnu branch. (check-in: 350627f3b1 user: drh tags: begin-concurrent-pnu-wal2) | |
| 14:11 | Merge recent enhancements and fixes from trunk. (check-in: 35eae71a4d user: drh tags: wal2) | |
| 13:48 | Merge all recent enhancements and fixes from trunk. (check-in: 110a081f12 user: drh tags: begin-concurrent-pnu) | |
| 13:34 | Merge fixes and enhancements from trunk into begin-concurrent. (check-in: 95ba2f50fd user: drh tags: begin-concurrent) | |
| 12:49 | Merge all recent enhancements and fixes from trunk into the apple-osx branch. (check-in: dadedf41c7 user: drh tags: apple-osx) | |
|
2020-01-14
| ||
| 16:50 | Fix the urifuncs.c extension (used for testing and debugging only) so that the sqlite3_filename_database() SQL function and its siblings correctly handle an invalid schema name passed in as the argument. (check-in: 3d7434a9d8 user: drh tags: trunk) | |
| 16:39 | Remove an ALWAYS on a branch for improved database corruption detection in btree.c:freeSpace(). Test case found by dbsqlfuzz. (check-in: 54bf048119 user: drh tags: trunk) | |
| 16:33 | Add the new noop_nd() debugging function to the noop.c extension. (check-in: 72911fb1b0 user: drh tags: trunk) | |
| 13:24 | For the showdb utility program, more accurate detection of when the database is in autovacuum mode for the "pgidx" subcommand. (check-in: 9ce2192b81 user: drh tags: trunk) | |
| 13:13 | Fix a minor typo on a comment in the CLI implementation. (check-in: db4fb3503c user: drh tags: trunk) | |
| 00:52 | Improvements to sqlite3_open_v2() documentation. (check-in: 4c4fd62a09 user: drh tags: trunk) | |
|
2020-01-13
| ||
| 15:25 | More documentation updates. No code changes. (check-in: a684d4ef08 user: drh tags: trunk) | |
| 13:33 | Documentation updates. No changes to code. (check-in: cc0e0aa3a7 user: drh tags: trunk) | |
|
2020-01-12
| ||
| 22:38 | Better than removing the incorrect assert() is to change it into a testcase() together with a comment indicating where an appropriate test case can be found, and the ticket that provoked the change. Ticket [614b25314c766238] (check-in: 3e3c60d812 user: drh tags: trunk) | |
| 22:25 | Change the zipfile virtual table so that the xBestIndex method gives a reasonable cost estimate even if no filename is specified. The missing filename error continues to be raised in the xFilter method. Meanwhile, the more reasonable cost estimate avoids unnecessary wierdness in the query planner. (check-in: 0e468aa6de user: drh tags: trunk) | |
| 22:20 | Remove an incorrect assert(). Fix for ticket [614b25314c766238] (check-in: 6a999c5aa0 user: drh tags: trunk) | |
|
2020-01-11
| ||
| 21:08 | New apis: sqlite3_filename_database(), sqlite3_filename_journal(), and sqlite3_filename_wal(). Also sqlite3_uri_key(). And the other sqlite3_uri functions now work using the journal or wal filename in addition to the database file. And the sqlite3_db_filename() result is guaranteed to work as an argument to the sqlite3_uri functions. (check-in: fd7bcc5352 user: drh tags: trunk) | |
| 20:27 | Minor changes for consistency between sqlite3_filename_wal() and sqlite3_filename_journal(). (Closed-Leaf check-in: 9a70ff43a7 user: drh tags: enhanced-uri) | |
| 16:08 | Redesign for better legacy compatibility. Add the sqlite3_uri_key() interface. (check-in: bcb43d11c4 user: drh tags: enhanced-uri) | |
|
2020-01-10
| ||
| 18:05 | Rearchitect the way in which filenames are stored in the Pager object so that the sqlite3_uri_parameter() interface will work from journal and WAL filenames too. This check-in implements the central idea, and compile and runs somewhat, but crashes on an extended test. (check-in: 2ae77bd233 user: drh tags: enhanced-uri) | |
| 01:05 | Fix to the register validity tracking logic in debug builds. No impact on release builds. (check-in: 0a500da6aa user: drh tags: trunk) | |
| 00:20 | Begin making changes to turn off trusted schema in command-line tools that open SQLite databases. There are a lot of these, and a lot of places to change, which makes me wonder if trusted schema should be off by default. (Leaf check-in: 3d23a275ab user: drh tags: default-untrusted-schema) | |
| 00:00 | Documentation updates on newer APIs. No changes to code. (check-in: 8845a8c22a user: drh tags: trunk) | |
|
2020-01-09
| ||
| 23:07 | Fix the fossildelta.c extension so that it will compile on mingw. (check-in: 20237d5dc4 user: drh tags: trunk) | |
| 20:44 | Merge in the untrusted-schema enhancements. See doc/trusted-schema.md for details. (check-in: 5720924cb0 user: drh tags: trunk) | |
| 20:33 | Only register the fts3_tokenizer() function using a single text encoding. (check-in: 966964af10 user: drh tags: trunk) | |
| 20:33 | Fix a harmless compiler warning. (check-in: edbf911fde user: drh tags: trunk) | |
| 20:11 | Fix an assert() in window.c that could fail with some obscure SELECT statements that use window functions. Ticket [678ecf429f8d1a5f] (check-in: 83dc55679a user: dan tags: trunk) | |
| 16:28 | Fix a problem in the encoding display in the updated PRAGMA function_list. (Closed-Leaf check-in: 318ff7720b user: drh tags: new-security-options) | |
| 16:00 | Fix minor typos in the trusted-schema.md document. (check-in: 87aea3ab1c user: drh tags: new-security-options) | |
| 15:18 | Minor formatting changes in the trusted-schema.md document. (check-in: 55553b5e5e user: drh tags: new-security-options) | |
| 14:51 | Design notes for the new-security-options branch. (check-in: af7c1ed4f8 user: drh tags: new-security-options) | |
| 13:08 | Simplified error message for the unsafe use of a virtual table. (check-in: d662129a60 user: drh tags: new-security-options) | |
| 01:20 | Fix a problem that restricted edgy functions in TEMP tables. New test cases added. (check-in: 8878c40753 user: drh tags: new-security-options) | |
|
2020-01-08
| ||
| 22:22 | Block edgy functions used in DEFAULT constraints. (check-in: da434dc149 user: drh tags: new-security-options) | |
| 20:37 | Performance improvements and test cases added. Allow "PRAGMA trusted_schema=ON" (check-in: 30882ca80f user: drh tags: new-security-options) | |
| 17:28 | Check for whether or not it is safe to use non-innocuous functions as the function is being coded, not when its name is resolved. (check-in: 1da802d54b user: drh tags: new-security-options) | |
| 15:44 | Provide the -innocuous option to the "db func" method in the TCL interface. (check-in: 0138652b6c user: drh tags: new-security-options) | |
| 15:43 | Fix the rot13.c extension to be deterministic. Add the noop.c extension. (check-in: a679122ca8 user: drh tags: new-security-options) | |
| 14:39 | In the TreeView debugging output, show a "DDL" mark on SrcList and Expr nodes that derive from a non-TEMP schema. (check-in: fe7472fd2a user: drh tags: new-security-options) | |
| 13:08 | Merge recent changes from trunk. (check-in: 5962921fce user: drh tags: new-security-options) | |
| 12:17 | When doing a text-to-double conversion on a BLOB with an odd number of bytes and assuming a UTF16 encoding, ignore the last byte. Ticket [9eda2697f5cc1aba]. (check-in: 1c76f1d8ec user: drh tags: trunk) | |
| 11:36 | Fix a minor formatting error in the display of BLOB values during VDBE tracing. (check-in: 295442887a user: drh tags: trunk) | |
| 10:57 | Improvements to the documentation of sqlite3_create_collation(). (check-in: fa866aec56 user: drh tags: trunk) | |
| 04:36 | Simplification of the logic in the constant-propagation optimization. (check-in: 1c3e5c20a9 user: drh tags: trunk) | |
| 01:43 | Fix the constant propagation optimization so that it does not try to propagate constant expressions that have affinity. Ticket [82ac75ba0093e5dc] (check-in: 6db1c3498f user: drh tags: trunk) | |
| 00:39 | Fix a misworded comment. No code changes. (check-in: ee0bc7ede0 user: drh tags: trunk) | |
|
2020-01-07
| ||
| 19:45 | Create the "trusted_schema" pragma. Add sqlite3_vtab_config() calls to set the risk rank for many virtual tables. (check-in: 4c21373c21 user: drh tags: new-security-options) | |
| 18:10 | Enforce SQLITE_VTABRISK restrictions. (check-in: 3d87ff312e user: drh tags: new-security-options) | |
| 18:10 | Fix a performance regression caused by the previous check-in. (check-in: d7d98d3dff user: drh tags: trunk) | |

| 09:06 | Fix an instance of an undefined behaviour (a left-shift of a 64-bit unsigned integer by a value greater than 64) that could occur in fts3. (check-in: e1f12978b5 user: dan tags: trunk) | |
|
2020-01-06
| ||
| 20:48 | In the typeof() optimization in OP_Column, expand the size of the bogus buffer provided for data so that it is big enough to cover the increased number of bytes displayed during register tracing from check-in [54553bf16fabd72d]. This is the correct fix for ticket [bbd55a97e66ff50d], though the earlier one does not hurt and is useful to retain. (check-in: e1154c39ba user: drh tags: trunk) | |
| 19:30 | Merge enhancements from trunk. (check-in: 9c50f6c28a user: drh tags: new-security-options) | |
| 19:23 | Rewrite the (debugging use only) sqlite3VdbeMemPrettyPrint() function to use the safer StrAccum interface rather than writing directly into a static string buffer.
