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

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

2019-04-25
19:23

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. check-in: d2728192 user: drh tags: trunk

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
00:48
Add new APIs to the extension loading mechanism. check-in: 6f122faf user: drh tags: trunk
00:34

Change the fts3_tokenizer() function to always return the pointer as a BLOB as long as the first argument is a bound parameter, regardless of the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER setting. check-in: 27160df7 user: drh tags: value_frombind
15:21
Remove the unused P5 flag from the OP_Rewind opcode. check-in: c2edbf3b user: drh tags: trunk

Fix a fairly obscure problem causing the planner to sometimes choose sub-optimal plans for a query with a single virtual table in the FROM clause, and at least one IN(...) constraint in the WHERE clause. check-in: f5752517 user: dan tags: trunk
11:48
Fix typos in the comments of the sessions extension, one of which affects the generated documentation. No code changes. check-in: 040d5d51 user: drh tags: trunk

13:53
Show the pointer address for Window objects in the TreeView display. check-in: 1ae70ad2 user: drh tags: trunk
13:35
More improvements to TreeView output for Window objects: (1) Show when the frame-spec is implied rather than explicit. (2) Move the FILTER clause out from within the OVER clause, making it a sibling of the OVER clause, to match syntax. check-in: d6a07433 user: drh tags: trunk
13:03
Improved TreeView display of Window objects. Change the Window.eType field to Window.eFrmType to avoid confusion with other "eType" values. check-in: ec2f207d user: drh tags: trunk
04:03
If the string formatter in sqlite3NestedParse() fails due to an over-length string, make sure this error is recorded by the parser so that it knows to fail. check-in: 85e53ff1 user: drh tags: trunk

Fix an obsolete comment in the CLI. No code changes. check-in: fade103c user: drh tags: trunk
21:56
In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. check-in: e775ef00 user: drh tags: trunk
21:55
Remove a test from the index build logic which is no longer needed and is in fact unreachable. check-in: 9b20ee10 user: drh tags: trunk
21:35
Change the name of the parameter table in the CLI to "sqlite_parameters". Doing so involves adding SQLITE_DBCONFIG_WRITABLE_SCHEMA and allowing the creation of tables whose names begin with "sqlite_" and that are indexed while writable_schema is on. check-in: 24ef3844 user: drh tags: trunk
19:50
Earlier detection of corruption while added to the freelist. check-in: 8c80b004 user: drh tags: trunk
18:44
Fix a faulty assert() statement in balance_nonroot() - the assert() should use get2byteNotZero() instead of get2byte() for the corner case where the number cells is zero on a 65536-byte page. check-in: bcbe7d96 user: drh tags: trunk
15:09
Improvements to the help text in the CLI. check-in: 919fec91 user: drh tags: trunk
15:06
Fix the writefile() SQL function implemented by ext/misc/fileio.c such that any directories created have standard umask permissions, not permissions of the file that is to be written. check-in: f11c8959 user: drh tags: trunk
14:24
For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. check-in: 191a023a user: drh tags: trunk

Fix a problem with a window function in a correlated sub-query where at least one reference to the outer SELECT appears in a FROM clause sub-select. Closed-Leaf check-in: 9aca86f9 user: dan tags: window-functions
13:53
We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). check-in: 7a0a26ed user: drh tags: trunk
11:38
Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. check-in: b99f8512 user: drh tags: trunk

13:51
Remove assert() statements based on the counter-factual proposition that 0 is not a valid cursor number. check-in: c7b33618 user: dan tags: window-functions
2019-03-20
20:27
Experimental change to apply affinity before running CHECK constraints on an INSERT. Note that in the CHECK constraints, REAL affinity really is REAL affinity, and not numeric affinity. This causes failures in some tests that are assuming affinity is applied after CHECK constraints. Leaf check-in: 9ef69d18 user: drh tags: apply-affinity-first
18:22
In the CLI, give better error messages if something goes wrong with the ".dbinfo" command. check-in: 3649a77b user: drh tags: trunk

Fix harmless compiler warnings from MSVC. check-in: f0f02d46 user: drh tags: trunk
11:16
Enhance the rtreenode() function of rtree (used for testing) so that it uses the newer sqlite3_str object for better performance and improved error reporting. Test cases added to TH3. check-in: 90acdbfc user: drh tags: trunk

17:45
Add tests to ensure that the window functions implementation is not generating code for unnecessary sorts. check-in: e195948a user: dan tags: window-functions
16:49
Add missing VdbeCoverage() macros to new code in window.c. check-in: 4f9b93e6 user: dan tags: window-functions
15:36
When computing the amount of scratch memory needed during a rebalance operation, assume the worst case for the number of cells per page, rather than relying on the BtPage.nCell value, which might be incorrect for a corrupt database. check-in: a420ebd0 user: drh tags: trunk
11:56
Revert the OP_MustBeInt opcode implementation on this branch so that it again matches trunk. The extra functionality is no longer required. check-in: c02f77b1 user: dan tags: window-functions
