2023-11-29
16:26
Fix a duplicate assert() caused by the second cherrypick in the previous check-in. (Leaf 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)
2022-09-27
17:00
Fix a potential division by zero error in this version of RBU that might occur if an external client checkpoints a wal file created by a suspended RBU process. (Leaf check-in: 73edd93a user: dan tags: branch-3.14)
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)

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: 56869f54 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: 4b73e151 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: d2e67220 user: dan tags: branch-3.28a)
2021-07-12
15:00

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: 0c3838d9 user: dan tags: reuse-schema-3.31)
2020-11-20
11:17
Declare a variable "const" in order to avoid compiler warnings. (check-in: 4f5481bf user: dan tags: wal2)
2020-11-19
16:08
Fix things so that sqlite3_database_file_object() works with wal2 filenames. (check-in: c2426ae8 user: dan tags: wal2)
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)
2020-09-16
16:48
Do not invoke usleep() for more than 999999 microseconds. (check-in: 1f0055d0 user: dan tags: branch-3.33)

16:40
Correctly handle expressions like "x IS (not) true/false" within the rhs of IN() expressions. Fix for [f3ff1472]. (check-in: 42361033 user: dan tags: branch-3.33)
16:39
Fix a crash that could occur in SQLITE_MAX_EXPR_DEPTH=0 builds when processing SQL containing syntax errors. (check-in: 6438db45 user: dan tags: branch-3.33)
16:38
Do not skip over TK_IF_NULL_ROW operators when bypassing TK_COLLATE operators. Fix to check-in [ac31edd3eeafcef4] which was itself a fix for ticket [45f4bf4eb4ffd788]. (check-in: 85041611 user: dan tags: branch-3.33)
2020-09-15
12:29
Do not invoke usleep() for more than 999999 microseconds. (check-in: 1f5ed852 user: drh tags: trunk)
2020-09-11
15:01
Catch fts5 index corruption caused by issuing 'delete' commands with incorrect data earlier in some cases. Also fix a couple of test script problems. (check-in: b79f19ed user: dan tags: trunk)
2020-09-10
15:09
Try again to fix the typo in the sqlite3_txn_state() documentation. (check-in: 6d1ab040 user: drh tags: trunk)

2020-09-05
06:21
Fix a bug in Lemon that might cause it to crash if there is a multi-terminal token with a space following the "|" separator. This does not affect SQLite. (check-in: 430c5d1d user: drh tags: trunk)
2020-09-04
19:12
Merge tsan error fix from trunk into this branch. (check-in: 93cc60b3 user: dan tags: reuse-schema)

Fix reporting on locks from external processes. Various other fixes. (check-in: 459de23e user: dan tags: shmlock-vtab)
2020-09-01
20:56
Add file-controls and a vtab frontend for querying the unix VFS for the currently held shm-locks. Still some issues. (check-in: ef10e1b3 user: dan tags: shmlock-vtab)
19:02
Fix harmless compiler warning. (check-in: a711e8cd user: mistachkin tags: trunk)
12:26
In the Lemon output, add a prefix comment that explains that the output file is automatically generated and shows the name of the source file. (check-in: d34caf3b user: drh tags: trunk)
11:20
Lemon updates: (1) include the #defines for all tokens in the generated C file, so that the C-file can be stand-alone. (2) If the grammar begins with a %include {...} directive on line one, make that directive the header for the generated C file. (3) Enhance the lemon.html documentation. (check-in: 84d54eb3 user: drh tags: trunk)
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)
01:52

00:26
Fix a harmless compiler warning. (check-in: 3ca0b7d5 user: drh tags: trunk)
00:09
Minor changes - fix a compiler warning and add an assert(). (Closed-Leaf check-in: 07222dce user: drh tags: in-early-out-fail)

20:27
Restore the "PRAGMA noop_update" feature that was broken by [2b3241cf67c8eea7]. (check-in: 5fa4cbcb user: dan tags: begin-concurrent-pnu)
19:58
Merge the SEEK_COUNT instrumentation enhancement from trunk. (check-in: 689ede95 user: drh tags: in-early-out-fail)
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)
18:49
New test-control that returns the number of calls to sqlite3BtreeMovetoUnpacked() on the main database and then resets the counter. This only works for SQLITE_DEBUG builds. (check-in: dca5b919 user: drh tags: trunk)
16:31
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 2020-08-31: This experiment did not work out. A better approach is now on trunk. (check-in: e9d983c6 user: drh tags: in-early-out-fail)
12:29
Fix the documentation for the OP_IdxGT family of opcodes to show that the P5 operand is not used. (check-in: 62f7d2a6 user: drh tags: trunk)
2020-08-29
19:00
Fix a sanitizer warning in zipfile.c. (check-in: ded1a75b user: dan tags: trunk)
15:36
Improve performance of wal-mode locking on unix in cases where there are hundreds of connections to a single database within the same process. (check-in: 30214727 user: dan tags: begin-concurrent-unixshmlock-opt)
15:15
Improve performance of wal-mode locking on unix in cases where there are hundreds of connections to a single database within the same process. (check-in: a1c19eea user: dan tags: trunk)
2020-08-28
20:01
Fix handling of an xShmLock(SHARED, UNLOCK) call when the caller does not hold any lock on the specified slot, but another connection in the same process holds an EXCLUSIVE. (Closed-Leaf check-in: 3eb36502 user: dan tags: unixshmlock-opt)
19:27
Modify the unixShmLock() function to avoid iterating through the (possibly large) set of connections to the same database file. (check-in: e0faddf0 user: dan tags: unixshmlock-opt)
18:47
Add the miscellaneous 'series' extension to the shell. (check-in: fc0856dc user: mistachkin tags: trunk)
13:10
Update Lemon documentation. Patches from sgbeal. (check-in: f5dc8344 user: drh tags: trunk)
12:58
Fix a couple of unreachable branches. (check-in: f2d26f2b user: drh tags: trunk)
11:19

10:50
If the argument to the ".read" command in the CLI begins with "|" then run the remainder of the argument as a command and read input from the output of that command. (check-in: 6c716f4b user: drh tags: trunk)
2020-08-25
19:09
Add support for the sqlite3_txn_state() interface. (check-in: ad195e3d user: drh tags: trunk)
2020-08-24
23:44
Reduce the N in the logN term for the sorting cost associated with computing DISTINCT by B-Tree by half, under the assumption that the DISTINCT will eliminate about half the rows of output. This is really a wild guess. But we do not have any better way of estimating what the row-count reduction due to DISTINCT will actually be. (check-in: 8787417e user: drh tags: trunk)
10:52
Correctly handle expressions like "x IS (not) true/false" within the rhs of IN() expressions. Fix for [f3ff1472]. (check-in: 493a2594 user: dan tags: trunk)
2020-08-20

2020-08-19
23:51
Try to make SQLite easier to compiler for Mac Catalyst. See forum post 803387a1c5. (check-in: e1595a20 user: drh tags: trunk)
23:32
Do not skip over TK_IF_NULL_ROW operators when bypassing TK_COLLATE operators. Fix to check-in [ac31edd3eeafcef4] which was itself a fix for ticket [45f4bf4eb4ffd788]. (check-in: 871f2ddc user: drh tags: trunk)
15:24
Update releasetest_data.tcl so that the "Fast-One" configuration runs bigmmap.test as part of release testing. (check-in: a0aa35aa user: dan tags: trunk)
15:21
Fix a problem in test file bigmmap.test. (check-in: d8e47382 user: dan tags: trunk)
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)
09:11
Fix the -quote option on the CLI to set the correct column separator. (check-in: c778f829 user: drh tags: trunk)
2020-08-16
00:30
Optimization to sqlite3BeginWriteOperation(). (check-in: 2173d4c6 user: drh tags: trunk)
2020-08-15
23:48
Optimization of the sqlite3SrcListDelete() routine. (check-in: 1b4acd1a user: drh tags: trunk)
22:23
Remove more unnecessary sqlite3GetVdbe() calls, replacing them with assert()s. (check-in: b7dc9321 user: drh tags: trunk)
21:55
Avoid unnecessary calls to the sqlite3GetVdbe() routine. Add assert() statements to prove each call is unnecessary. (check-in: 86d3790c user: drh tags: trunk)
19:58
Omit the unnecessary not-NULL check on the upper bound of a forward index range scan. The subsequent OP_IdxGT will always catch the NULL. Similarly, omit the not-NULL check on the lower bound of a reverse index range scan, as the SeekLE opcode will disallow the NULL. (check-in: e51ecadc user: drh tags: trunk)
2020-08-14
21:51
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: 7fee0b10 user: drh tags: trunk)
21:37
Update the version number to 3.34.0 for the next development cycle. (check-in: 70f34f3d user: drh tags: trunk)
21:32
Optimizations to the logic that converts main table accesses into equivalent index accesses. Code is now slightly smaller and faster than trunk. (Closed-Leaf check-in: 611b6404 user: drh tags: delete-bytecode-optimization)
20:04
For UPDATE and DELETE, use OP_DeferredSeek always. If the seek must later be resolved, add the OP_FinishSeek opcode after all WHERE clause terms have been processed. This obviates the need for the WHERE_SEEK_TABLE and WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing complication, and it allows the covering index optimization to be used further into WHERE clause processing. (check-in: a495f60d user: drh tags: delete-bytecode-optimization)
17:39
Experimental change to try to get some DELETE operations to access values using the index rather than the main table, so as to avoid unnecessary main table seeks. (check-in: 2f7cb6ab user: drh tags: delete-bytecode-optimization)
16:14
Fix an inconsequential memory leak in sqldiff. Update the "Sanitize" case in wapptest.tcl to use -fsanitize=address,undefined, and to run more tests. (check-in: 613fb5c2 user: dan tags: trunk)
13:55
Merge the 3.33.0 release into the reuse-schema branch. (check-in: e456d437 user: drh tags: reuse-schema)
13:23
Version 3.33.0 (check-in: fca8dc8b user: drh tags: trunk, release, version-3.33.0)
2020-08-13
17:27
Fix "make test" handling of environment variable QUICKTEST_OMIT so that it can be used to exclude test files in other than the main test directory. (check-in: b0509760 user: dan tags: trunk)
2020-08-12
16:19
Improvement on the previous fix. (check-in: f6cffa2d user: drh tags: trunk)

Fix harmless USAN warnings from gcc9. (check-in: 72c4c69f user: drh tags: trunk)
18:17
New test cases for the use of the ieee754 and decimal extensions in the CLI. (check-in: bc1590f3 user: drh tags: trunk)
