12:37
Use compile-time options SQLITE_QUERY_PLANNER_LIMIT and SQLITE_QUERY_PLANNER_LIMIT_INCR to control the value for WhereLoopBuilder.iPlanLimit, rather than embedding magic numbers in the code. check-in: 903e5018 user: drh tags: trunk
10:47
Increase the initial value of WhereLoopBuilder.iPlanLimit to 20K. Issue a warning if the iPlanLimit reaches zero. check-in: 3dd35f51 user: drh tags: trunk
2018-09-23
02:01

Fix harmless compiler warning when compiled with SQLITE_OMIT_AUTHORIZATION. check-in: 50f2fa19 user: mistachkin tags: trunk
19:06
Comment typo fixed. No code changes. check-in: 7e68cdab user: drh tags: trunk
18:43
Put a limit counter on the query planner that restricts the number of index+constraint options that can be considered for each table in a join. This prevents certain pathological queries from taking up too much time in the query planner. check-in: 8690b5a0 user: drh tags: trunk
13:07
Optimization to the OP_MakeRecord opcode makes speed-check.sh run about 1.1 million cycles faster, and results in a slightly smaller library. check-in: d10e6362 user: drh tags: trunk
2018-09-20
20:43
Minor code simplification. check-in: 22ae8a52 user: drh tags: trunk
20:15
Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. check-in: 7edd26ed user: drh tags: trunk
19:02
Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. check-in: ad130bb8 user: drh tags: trunk
2018-09-19
17:09

17:00
Enhance tester.tcl so that when "--malloctrace=1" is specified, the test generates self-contained Tcl scripts that present GUIs instead of *.sql files that require a separate program to interpret. check-in: de2e3cbd user: dan tags: trunk
16:06
Minor improvements to the permutations.test script. Most notably, a command like "permutations.test alter%" now runs all test scripts with names that match the LIKE pattern "alter%". Or, say, "permutations wal alter%" to run all alter% tests in wal mode. check-in: 3e1a2f66 user: dan tags: trunk
2018-09-17
20:47

Add the new "explain" virtual table in ext/misc. Use this virtual table for additional test cases for the optimization that avoids updating indexes on expressions when none of the columns changed by the UPDATE are in the expression. check-in: 2404304c user: drh tags: trunk
15:01
Improved presentation on the new code that prevents unnecessary writes to expressions on indexes during an UPDATE when the expression does not reference any of the columns that are changing. check-in: c9f04529 user: drh tags: trunk

2018-09-11
19:05
Do not do the byte-by-byte modifications in the resetdb.test script if the reserved-byte flag in the DB header is non-zero, because in that case the bytes will be in the wrong place and the test won't work. check-in: 0af18674 user: drh tags: trunk

20:52
Fixes to the UPDATE logic in Geopoly. check-in: 7c3cee0a user: drh tags: trunk
20:24
Also free up the MEM_RowSet bit in the Mem.flags field and have RowSet objects be destroyed using Mem.xDel. This change results in faster code. check-in: f48e9feb user: drh tags: trunk
18:47

2018-08-15
14:03
Allow sqlite3_snapshot_open() to be called to change the snapshot after a read transaction is already open on database. check-in: 41399169 user: dan tags: trunk
2018-08-14
15:12
Fix UPSERT so that it checks the target-constraint first and fires the DO UPDATE if that constraint is violated regardless of whether or not other constraints are in violation. This aligns SQLite behavior with what PostgreSQL does. Fix for ticket [908f001483982c43cdb476dfb590a1a]. check-in: 529fb55e user: drh tags: trunk
2018-08-13
22:50
Stop requiring the global VFS mutex to access the unixInodeInfo.pUnused field. The unixInodeInfo mutex is sufficient. check-in: e3ea43da user: drh tags: trunk
20:46
Take extra precautions to ensure access to unixInodeInfo.pUnused is protected by all necessary mutexes. check-in: 8b1e0010 user: drh tags: trunk
11:32
Fix an incorrect comment on the unix-nolock VFS object. No functional code changes. check-in: 90f7c193 user: drh tags: trunk
2018-08-09
21:45
Fix the isLikeOrGlob() routine in the WHERE clause processing logic so that it avoids signed/unsigned character comparisons, as that can lead to an incorrect answer if the ESCAPE clause is an invalid UTF8 string. Problem found by OSSFuzz. check-in: 4195a3f8 user: drh tags: trunk
18:36
When a column must be a constant due to WHERE clause and the value of that column is being coded as a constant, make sure the affinity is correct. check-in: 7404ea83 user: drh tags: trunk
2018-08-08
20:46
Minor style improvements. check-in: 60bbca2b user: mistachkin tags: trunk
2018-08-06
02:08
Enhance the edit() function so that it converts text from \r\n back into \n only if the original unedited copy contained no \r\n values. check-in: 20c995d3 user: drh tags: trunk
01:39
Add the --info option to the fuzzcheck test utility. check-in: 1caaaaa7 user: drh tags: trunk
01:21
Fix an overzealous assert() statement discovered by OSSFuzz. check-in: d9c9fe9f user: drh tags: trunk
2018-08-04
20:30
Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. check-in: cdff3af7 user: drh tags: trunk
15:28
Add test cases for the constant expression fix of the previous check-in. check-in: 95db5bd9 user: drh tags: trunk
15:16
Ensure that all expressions that are to be evaluated once at the start of a prepared statement (the Parse.pConstExpr expressions) pass the sqlite3ExprIsConstantNotJoin() test. It is not sufficient to pass just the sqlite3ExprIsConstant() test as that would allow through column references that are bound to constants by the WHERE clause in the constant propagation optimization. This fixes a problem discovered by OSSFuzz. check-in: 8bc7f84c user: drh tags: trunk
2018-08-03
20:19
Fix the handling of sub-queries with LIMIT clauses by the optimization activated by compile-time symbol SQLITE_COUNTOFVIEW_OPTIMIZATION. check-in: 21235d9a user: dan tags: trunk
15:58
Fix the OP_SeekRowid opcode so that it has no type-change side-effects on the key register in P3. This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time. Test cases for this fix are in TH3. check-in: fa94b49e user: drh tags: trunk
13:56
Improve "PRAGMA vdbe_trace=ON" to always show the key values for the OP_IdxGT and related opcodes. check-in: 0f881955 user: drh tags: trunk
2018-07-29
18:56
In the command-line shell, always exit if realloc() fails. check-in: e390023c user: drh tags: trunk
2018-07-28
21:01
Add a small cost penalty to sorting to bias the query planner in favor of plans that do not require a final sorting pass. check-in: 85b9beb4 user: drh tags: trunk
16:24
Do not allow a column reference that is converted into a constant by the WHERE-clause constant propagation optimization to be moved to the init-time constant expression list, as the table reference will not work there. This fixes a problem found by OSSFuzz. check-in: d30b2a94 user: drh tags: trunk
14:56
Fix an assert() statement that was made obsolete by the constant propagation enhancement. Problem discovered by OSSFuzz. check-in: e4b4737e user: drh tags: trunk
14:34
Improved debugging output when the ".selecttrace" option is used in the shell. check-in: fcb88dd6 user: drh tags: trunk
2018-07-27
23:33
Improvements to the parser to increase coverage. Fix the parser so that at least one expresssion is required after PARTITION BY and within the list of expressions on VALUES(). check-in: 02204f8b user: drh tags: trunk
22:55
When doing a DROP VIEW do not try to delete entries from the sqlite_stat1 table as there are none. check-in: 7efdba2b user: drh tags: trunk
22:14
Minor grammar changes that help the parser run faster by reducing the number of NUL rule reductions. check-in: cfd1b005 user: drh tags: trunk
20:45
Enhance Makefile for MSVC to support building the shell tool without using the amalgamation. check-in: 3d815d83 user: mistachkin tags: trunk
20:37
The WHERE-clause constant propagation optimization attempts to use transitive laws to replace column values with constants in the WHERE clause in order to help to query planner make more aggressive optimizations. check-in: f4229707 user: drh tags: trunk
2018-07-26
21:48
In the unix VFS, give every unixInodeInfo object its own mutex, rather than using the global VFS mutex, to improve concurrency in cases where there are many threads operating on separate database files. check-in: 22f47cf4 user: drh tags: trunk
2018-07-25
15:25

Change the SQLITE_Stat34 bit of the optimization test-control so that it prevents STAT4 data from being used but allows it to be loaded into the Index objects. This permits STAT4 to be turned on and off on a per-statement basis. check-in: 489f3caf user: drh tags: trunk
15:44
New checks in PRAGMA integrity_check to validate the autovacuum settings in the header. check-in: a4663f09 user: drh tags: trunk

2018-07-10
23:31
Remove incorrect ALWAYS() macros from the window function logic. check-in: 94ac51cc user: drh tags: trunk
22:24
Add VdbeModuleComment()s on the three main code generators for window functions. check-in: f7c239e9 user: drh tags: trunk
20:50
Minor comment changes. Add ALWAYS() macros on some unreachable branches in the xStep() methods of built-in window functions. check-in: f2057542 user: drh tags: trunk
19:48
Identify Select objects within a single statement using small sequential integers rather than "0x%p". This is more readable and yields the same result on successive runs. check-in: a7cdc5bc user: drh tags: trunk

Fix a problem with using scalar sub-selects in window function queries. check-in: 687fe532 user: dan tags: trunk
17:10
Further improvements to bytecode branch testing. Fix cases where the macros said a branch could not be taken when in fact it could be. Alter some window function branch coverage macros to indicate that comparison operands cannot be NULL. check-in: 76e42b70 user: drh tags: trunk
16:04
Enhancements and improved documentation to the byte-code branch coverage testing logic. Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer). check-in: cd2da7e1 user: drh tags: trunk
07:39
Fix a harmless warning about comment formatting in the previous check-in. Simplify the ORDER BY dereferencing logic so that it avoids unreachable branches. check-in: 0f6ec605 user: drh tags: trunk
07:25
Assert that if two functions compare equal in every other way, then they must both have OVER clauses, or neither has an OVER clause. Use this fact to simplify expression comparison. check-in: 52559ad5 user: drh tags: trunk
06:47
Enhance the sqlite3ExprCompare() routine so that it knows to compare the OVER clause of window functions. check-in: 0a7649af user: drh tags: trunk
06:32
Enhance the TreeView mechanism so that it shows the window function data structures as part of the abstract syntax tree. check-in: a2c0e1be user: drh tags: trunk

Simplification to the logic that detects misuse of the application-defined function creation interfaces. check-in: 8f21d778 user: drh tags: trunk
02:02
During WITHOUT ROWID table creation, if the sqlite3CreateTable() call fails due to an authorizer denying the INSERT into the sqlite_master table, then detect this fact and abort the CREATE TABLE early, to avoid an assertion fault. check-in: 164b1641 user: drh tags: trunk
2018-07-08
01:02
Identify specific FuncDef objects for window functions using the pointer to the function name (FuncDef.zName) rather than the pointer to the xStep method. This allows xStep method pointer to be replaced with a single noopStepFunc() procedure, and thus save having lots of different no-op step functions. check-in: 410e13b0 user: drh tags: trunk
2018-07-07
20:55
Simplifications to the implementation of the sum() SQL function. check-in: a8b13002 user: drh tags: trunk

Fix the JSON extension so that it can be compiled separately from the amalgamation. check-in: 4b8cfe7b user: drh tags: trunk
20:13
Fix an LSM problem caused by using the same cursor for equality and range scans. check-in: f05bead3 user: dan tags: trunk
19:47
Add ALWAYS() macros on results of sqlite3_aggregate_context() calls in xInverse() implements, since they can never fail. check-in: fdef2a92 user: drh tags: trunk
19:36
Add an assert() to help verify that OP_AggInverse is never called on an accumulator that has not previously been processed by OP_AggStep. check-in: 42138891 user: drh tags: trunk
17:38
Add missing VdbeCoverage() macro to window.c. check-in: 63f4d306 user: dan tags: trunk

Try to improve the error messages for misformed frame specifications in window definitions. check-in: 927b95a0 user: drh tags: trunk
14:31
Also disallow non-constant expressions in "<expr> PRECEDING" or "<expr> FOLLOWING" clauses. check-in: a6dffecc user: dan tags: trunk
14:15
Ensure an error is returned if the user specifies an unsupported frame type. check-in: 0f3f8fcd user: dan tags: trunk
13:48
Prevent "UNBOUNDED FOLLOWING" from being used as the starting boundary of a window-frame. And "UNBOUNDED PRECEDING" from being used as the ending boundary. check-in: e51fdf66 user: dan tags: trunk

Get the json_group_array() and json_group_object() SQL functions working as window functions. check-in: 916cdc83 user: drh tags: trunk
18:34
Return an error if a "RANGE" window-frame uses "<expr> PRECEDING" or "<expr> FOLLOWING". check-in: 786c87ba user: dan tags: trunk
