| ||
| 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) | |
|
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) | |
| 14:02 | Updates to the shared_schema.md notes document. (check-in: 51af2ade user: drh tags: reuse-schema) | |
| 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) | |
| 13:46 | In the CLI, add ".help" text for the .shared-schema command. (check-in: 3ba6f790 user: drh tags: reuse-schema) | |
|
2019-05-27
| ||
| 00:29 | Improved rounding even on systems with an 8-byte "long double" type. (check-in: 15202aee user: drh tags: trunk) | |
|
2019-05-25
| ||
| 18:17 | Performance enhancement in sqlite3AtoF(). About 8% faster. (check-in: 81721aa5 user: drh tags: trunk) | |
| 17:41 | Use "long double" literals to initialize an array of "long double" objects. (check-in: 2e2ebad3 user: drh tags: trunk) | |
| 13:14 | Add new cases to speedtest1 for measuring performance of binary to/from decimal conversions of floating point values. (check-in: b84e7057 user: drh tags: trunk) | |
| 00:17 | Disable the new rounding tests on systems without long double support. (check-in: ed250b4e user: drh tags: trunk) | |
|
2019-05-24
| ||
| 22:58 | Improvements to rounding behavior in the round() and printf() functions. (check-in: 641b2d21 user: drh tags: trunk) | |
| 13:15 | The ".shared-schema" command in the CLI requires the sqlite_dbpage table, so disable it if the build does not include that extension. (check-in: 0913ff4d user: drh tags: reuse-schema) | |
| 13:04 | Merge recent enhancements from trunk. (check-in: ff9f3e09 user: drh tags: reuse-schema) | |
| 11:55 | Fix an fts5 segfault that could occur after parsing a corrupt structure record. (check-in: 600daa9c user: dan tags: trunk) | |
|
2019-05-23
| ||
| 16:40 | Add test cases for the fix in the previous commit. (check-in: c1057b2a user: dan tags: trunk) | |
| 16:38 | Improvements to the view-self-join optimization so that it works on all VIEWs, not just on Common Table Expressions. (check-in: d2fe370c user: drh tags: trunk) | |
|
2019-05-22
| ||
| 23:12 | New test case for check-in [74ef97bf51dd531a] that takes the fix in the previous check-in into account. (check-in: cb1d0652 user: drh tags: trunk) | |
| 22:49 | Renumber the Select.selId values in the copies of SELECT statements that implement VIEWs when the VIEW is expanded, so that when the same VIEW is used twice in the same join, each expansion as a distinct selId. This fixes ticket [ce823231949d3abf42453c8]. (check-in: 3cacc4b9 user: drh tags: trunk) | |
| 14:35 | New dbsqlfuzz find added to test/fuzzdata8.db. (check-in: 42af7c81 user: drh tags: trunk) | |
| 14:22 | Fix a buffer overread that could in fts3 when dealing with corrupt records. (check-in: 1660d773 user: dan tags: trunk) | |
|
2019-05-21
| ||
| 17:04 | Combine the implementations of the key and hexkey pragmas into a single case. Have both pragmas return "ok" if they are implemented. (check-in: b3692c40 user: drh tags: trunk) | |
| 16:32 | Fix a problem in [b5ca442a] causing an assert() to fail in REINDEX commands. (check-in: a3e77c77 user: dan tags: trunk) | |
| 14:42 | Use a statement journal for all CREATE INDEX statements in case an indexed exprsesion throws an exception when it is evaluated. Fix for [b5ca442a]. (check-in: b8071d10 user: dan tags: trunk) | |
|
2019-05-20
| ||
| 19:46 | Fix a segfault that could occur in sqlite3session_diff() if NULL were passed as the pzErrMsg argument. (check-in: aee73fd2 user: dan tags: trunk) | |
| 18:43 | Improvements to the automatic compile-time selection of byte-order, as suggested on the mailing list by Seb Kemper. (check-in: b7aad929 user: drh tags: trunk) | |
| 18:35 | A minor variation on check-in [1685610ef8e0dc] which (hopefully) makes the logic a little easier to follow. Also disallows the use of the double-quoted string hack in the query expression used for VACUUM INTO, which is not strictly required, but moves us toward the goal of disallowing the double-quoted string hack everywhere. (check-in: 3e1b55f3 user: drh tags: trunk) | |
| 17:14 | Disallow string constants enclosed in double-quotes within new CREATE TABLE and CREATE INDEX statements. It is still possible to enclose column names in double-quotes, and existing database schemas that use double-quotes for strings can still be loaded. This addresses ticket [9b78184b]. (check-in: 1685610e user: dan tags: trunk) | |
| 10:36 | Update the sqlite3ExprCompare() routine so that it does not think "? IS NOT TRUE" is the same as "? IS TRUE". Fix for [d3e7f2ba5b3]. (check-in: 99eba69b user: dan tags: trunk) | |
|
2019-05-18
| ||
| 21:22 | Fix an assert() failure that could occur in a join query if the RHS of an IN() operator is a list containing correlated expressions. This problem was introduced by checkin [e130319317e7611938] which was part of the fix for ticket [787fa716be3a7f650c] - so this commit is part of that ticket's fix too. (check-in: 778b1224 user: dan tags: trunk) | |
| 19:49 | Avoid including the comment in the output of "PRAGMA table_info" in situations where there is a comment following a DEFAULT value within a CREATE TABLE statement. (check-in: d91095ba user: dan tags: trunk) | |
|
2019-05-17
| ||
| 20:37 | Disable PRAGMA journal_mode=OFF when SQLITE_DBCONFIG_DEFENSIVE is turned on. Ticket [f4ec250930342e0c]. (check-in: a0f5eb5c user: drh tags: trunk) | |
| 15:59 | Always store a REAL value in a column with REAL affinity if the integer equivalent would require 8 bytes of storage. Fix for [3c27b97e3]. (check-in: 14c00b10 user: dan tags: trunk) | |
|
2019-05-16
| ||
| 20:40 | Add test cases to test/fuzzdata7.db for (harmless) dbfuzz2 finds. (check-in: 1eb2a628 user: drh tags: trunk) | |
| 20:36 | Initialize the 18-byte overrun area on the buffer used to reconstruct overflow btree cells during a btree search, to avoid a harmless jump-depends-on-uninit-values warning. (check-in: 4b05caeb user: drh tags: trunk) | |
| 20:13 | Fix an assert() in the OP_Delete opcode that could fail with a corrupt database. (check-in: 915388ab user: dan tags: trunk) | |
| 16:44 | Add new test file fts5corrupt4.test. (check-in: 5dfc4fe9 user: dan tags: trunk) | |
| 11:47 | Fix a harmless use-of-initialized-value fault in the assert() logic added by check-in [d612fb7873cf59d] (check-in: 3dac9072 user: drh tags: trunk) | |
| 03:47 | Fix harmless compiler warning in the session extension. (check-in: dff823ca user: mistachkin tags: trunk) | |
| 01:22 | Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 string, even if the input strings are ill-formed. This is a followup to check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed. Also add assert()s to prove correct zero termination. (check-in: d612fb78 user: drh tags: trunk) | |
|
2019-05-15
| ||
| 18:42 | 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. (check-in: 05897ca4 user: drh tags: trunk) | |
| 10:16 | Simplify the "Verifying Code Authenticity" section of the README.md file. No code changes. (check-in: adebffc1 user: drh tags: trunk) | |
|
2019-05-14

| 21:51 | Merge the latest trunk enhancements into begin-concurrent. (check-in: 5d3a6e18 user: drh tags: begin-concurrent) | |
| 20:25 | Fix a problem with the fix for [9cf6c9bb51] (commit [658b84d7]) that could cause a cursor to be left in an invalid state following a (rowid < text-value) search. (check-in: bc7d2c16 user: dan tags: trunk) | |
| 19:39 | Merge recent enhancements from trunk into apple-osx. (check-in: 40362d51 user: drh tags: apple-osx) | |
| 19:20 | New test cases in test/fuzzdata8.db. (check-in: 228e1087 user: drh tags: trunk) | |

| 00:43 | Disable index seek optimizations on REINDEX when the order of primary keys in the index differs from the main table. Fix for ticket [bba7b69f9849b5bf11b4]. (check-in: f7aadfab user: drh tags: trunk) | |
|
2019-05-13

2019-05-11
| ||
| 19:36 | A new implementation for the sqlite3ExprImpliesExpr() theorem prover that does a better job of answering TRUE to "(NOT A) OR B" when B is a NOT NULL expression. (check-in: b3413197 user: drh tags: trunk) | |
| 16:14 | When considering partial indexes, do not assume that a "CASE x ..." expression implies "x IS NOT NULL". (check-in: 1b243032 user: dan tags: trunk) | |
| 13:04 | Do not assume that "x IS NOT ?" implies "x NOT NULL" when considering partial indexes. Fix for ticket [8025674847]. (check-in: 0ba6d709 user: dan tags: trunk) | |

| 14:26 | Treat integer values in window definition ORDER BY clauses as constants, not as references to another expression. (check-in: 7e4809ea user: dan tags: trunk) | |
| 14:03 | Improved comments and extra assert() statements on the OP_Savepoint opcode, just to make the code a little easier to read and reason about. (check-in: e80b2d9f user: drh tags: trunk) | |
| 12:14 | Fix the previous check-in [db9acef14d492121] so that the amalgamation build works for systems for which lack HAVE_ISNAN. (check-in: 3cc55e09 user: drh tags: trunk) | |
| 12:06 | Fix the round() SQL function so that it handles infinities correctly. (check-in: db9acef1 user: drh tags: trunk) | |

| 18:37 | Fix another small buffer overread in sqlite_dbdata triggered by a corrupt database page. (check-in: 1dfc95b8 user: dan tags: trunk) | |
| 18:33 | Fix a problem in the ".recover" command allowing a circular loop of b-tree pages in a database file to cause an infinite loop. (check-in: 8d2a062e user: dan tags: trunk) | |
| 18:13 | Make the ".schema" command in the CLI resistant to corrupt database files. (check-in: f22c7e22 user: drh tags: trunk) | |
| 17:54 | Fix a crash in the sqlite_dbdata module that could occur if a pointer within an overflow chain in a corrupt database pointed past the end of the db. (check-in: 3eae4e30 user: dan tags: trunk) | |
| 17:10 | Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes). This avoids corner cases of comparing integers against real values that are beyond the resolution of an IEEE 754 double. Fix for ticket [6c1d3febc00b22d457c78c2] (check-in: 9b091527 user: drh tags: trunk) | |
| 16:57 | Avoid long delays that can occur when ".recover"ing data from a database with a corrupt freelist. (check-in: 20f06bf2 user: dan tags: trunk) | |
| 16:22 | Improved debugging output from the OP_MakeRecord opcode. (check-in: ac790729 user: drh tags: trunk) | |

| 21:17 | Remove some stale references to the addopcodes.tcl script from documentation. (check-in: c0381b0b user: drh tags: trunk) | |
| 20:56 | Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space. But we have long since blown through that ceiling so the addopcodes.tcl script was just needless complexity. There is no longer any reason to keep it around.

| 18:12 | Small optimizations to the grammar for window functions save about 120 bytes of space in the parser tables. (check-in: bce01d95 user: drh tags: trunk) | |
| 17:45 | Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. (check-in: bc0fb1c3 user: drh tags: trunk) | |
| 17:45 | Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization. This is a feature, but we will keep it undocumented for now in case we later decide it is a bad idea. (check-in: 10aedce3 user: drh tags: trunk) | |

| 00:56 | Make sure the MEM_FromBind bit inthe Mem.flags field is not included in the MEM_TypeMask. This critical changes was omitted from the previous two check-ins by mistake, and so those check-ins are not fully functional. (check-in: f7ba2daf user: drh tags: trunk) | |

| 18:39 | The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. (check-in: fb125bd3 user: drh tags: trunk) | |
| 17:30 | Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. (check-in: e3fde56d user: drh tags: trunk) | |
