The OP_SeekScan opcode works, but using it requires disabling the IN-earlyout optimization because the OP_IfNoHope opcode might move the cursor. (Leaf check-in: f3c36b84 user: drh tags: in-scan-vs-index)
2020-09-28
19:51
Revisiting the IN-scan optimization to try to fix it for the corner case where the statistics deceive the query planner into using a scan when an indexed lookup would be better. This check-in changes the code generation to do the IN-scan using a new OP_SeekScan opcode. That new opcode is designed to abandon the scan and fall back to a seek if it doesn't find a match quickly enough. For this work-in-progress check-in, OP_SeekScan is still a no-op and OP_SeekGE still ends up doing all the work. (check-in: d720b698 user: drh tags: in-scan-vs-index)
15:49

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)
01:52
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: 35505c68 user: drh tags: trunk)

19:58
Merge the SEEK_COUNT instrumentation enhancement from trunk. (check-in: 689ede95 user: drh tags: 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

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)

2020-08-26
19:07
Enhance the ".databases" command in the CLI so that it shows the result of sqlite3_db_readonly() and sqlite3_txn_state() for each database file. (check-in: 0ffd16d2 user: drh tags: trunk)
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

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)
18:00
Modify a test for corruption within the wal checkpoint code to account for the pending-byte page. And for the fact that test configurations might move the pending-byte page. (check-in: 7dfb74c3 user: dan tags: trunk)
17:20
Minor comment fixes. No changes to code. (check-in: 533aeb90 user: drh tags: trunk)

13:22
Merge all the latest changes into the begin-concurrent-pnu-wal2 branch. (Leaf check-in: ebefcb86 user: drh tags: begin-concurrent-pnu-wal2)
11:34
Merge latest trunk changes into this branch. (Leaf check-in: 91262e66 user: dan tags: wal2)
2020-08-10
21:30

11:21

Fix minor test script problems. (check-in: 5d54cd44 user: dan tags: trunk)
2020-08-09

2020-08-08
20:15
Fix the check-in at [41474548ef3f7454] so that it computes the pointer in time for error checking at the end of the routine in the case of a non-OOM error. (check-in: 13d2fed7 user: drh tags: trunk)
20:11
