14:06
Run a test with TEST_REALLOC_STRESS and OMIT_LOOKASIDE defined as part of releasetest.tcl on Linux/x86-64. check-in: a1baf3a7 user: dan tags: trunk
13:38
If SQLITE_TEST_REALLOC_STRESS is defined, extend the op-code array used by virtual-machine programs by one element at a time, instead of doubling its size with each realloc(). check-in: 4c291827 user: dan tags: trunk

18:26
Update requirements marks. No changes to code. check-in: 7556bd9a user: drh tags: trunk
17:49
Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. check-in: bdaa6947 user: drh tags: trunk
17:25
Fix a buffer overrun in the previous commit. Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572]. check-in: 299b9570 user: dan tags: query-planner-fix
15:38
The SQLITE_IOERR_BLOCKED extended error code is not longer used, so remove assert() statements and documentation for that error code. Also make other documentation improvements. check-in: 36b7c5ce user: drh tags: trunk
12:51
Reworking the documentation on integer result codes. This is a comment and documentation change only. There are no changes to code. check-in: 54f1df7b user: drh tags: trunk
2014-08-07
20:42
When the estimated sorting cost overwhelms the estimated lookup cost, ensure that lookup costs are still taken into account when selecting a lookup algorithm. check-in: 2af630c5 user: drh tags: trunk
20:37

20:25
Remove the extraneous debugging printf() from the previous check-in. check-in: 8f04d2c0 user: drh tags: query-planner-fix
16:50
Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. check-in: ec5d84ba user: drh tags: query-planner-fix
2014-08-06
18:50
A couple more harmless compiler warnings eliminated. check-in: bcf6d775 user: drh tags: trunk

11:57
On the windows VFS, do not try to make InterlockedCompareExchange an overloadable function, since sometimes it is a macro. check-in: ab1a751e user: drh tags: trunk
11:49
Fix an obsolete comment in the func.c source file. No changes to code. check-in: 7a145c94 user: drh tags: sessions

02:03
Merge all recent changes from trunk. check-in: a353a851 user: drh tags: threads

01:08
Fix typos in the opcode documentation. Comment changes only. No changes to code. check-in: 717245d4 user: drh tags: trunk
00:29
A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. check-in: 0ad1ed8e user: drh tags: trunk
2014-08-05
21:31
Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. check-in: 29ba8128 user: drh tags: trunk
19:16
Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. check-in: 95286821 user: drh tags: trunk
11:04
Rename the internal Schema.flags field to Schema.schemaFlags. check-in: 5ae80b3c user: drh tags: trunk
00:53
Improved VdbeCoverage() macros. A few minor simplifications to generated VDBE code. Closed-Leaf check-in: 01f60027 user: drh tags: IN-operator-improvements
2014-08-04
21:26
Part of the change in the previous check-in was incorrect and can result in an incorrect UPDATE for WITHOUT ROWID tables. This check-in fixes the problem. check-in: ee5f6eae user: drh tags: IN-operator-improvements
18:50
Further enhancements to IN-operator processing. check-in: 7fdf26da user: drh tags: IN-operator-improvements
16:39
Refinements to the enhanced IN-operator logic. check-in: 92ba2821 user: drh tags: IN-operator-improvements
15:12
Changed my mind: This opcode name changes mere creates unnecessary diff marks between older and newer versions without significantly improving readability. Was: Rename the IsNull opcode to IfNull and rename the NotNull opcode to IfNotNull. Closed-Leaf check-in: 2f724cba user: drh tags: deadend
2014-08-02
21:03
Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. check-in: 436e8842 user: drh tags: IN-operator-improvements
20:44
Remove (newly) incorrect preprocessor check to fix build on WinRT. check-in: ba782654 user: mistachkin tags: trunk

21:00
Improved detection and handling of NULL values on the RHS of a IN operator. check-in: 468e7300 user: drh tags: trunk
18:00
Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. check-in: c11e55fa user: drh tags: trunk
15:51
Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. check-in: 7c6fbcfe user: drh tags: trunk
15:34
The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. Closed-Leaf check-in: e13175d3 user: drh tags: IN-operator-improvements
14:46
Begin making changes to the IN operator in an attempt to make it run faster and to make the code easier to understand. check-in: ee0fd6aa user: drh tags: IN-operator-improvements

Omit a pointless OP_Null when processing a value-list RHS of an IN operator where the LHS is a rowid. check-in: 1361450a user: drh tags: trunk
18:54
Optimizations to the OS sub-type checking in the Win32 VFS. check-in: 1e5489fa user: mistachkin tags: trunk

Fix a leaked database handle in pager2.test. check-in: 47457b04 user: dan tags: trunk
15:44
Deactivate the DISTINCT in a SELECT on the right-hand side of an IN operator, since it should not make any difference in the output but dues consume extra memory and CPU time. check-in: f4cb5365 user: drh tags: trunk
2014-07-30
23:11

Mark some invariants in the vdbesort.c logic when SQLITE_MAX_WORKER_THREADS==0. check-in: 721cd965 user: drh tags: threads
15:43
Add the "eForce" parameter to the sqlite3_multiplex_shutdown() entry point in test_multiplex.c. Shutdown is forced if true. Shutdown is not done if there are pending database connections and eForce is false, but an error log entry is made instead. check-in: c7303d01 user: drh tags: trunk
14:57

Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. check-in: 729ece40 user: drh tags: trunk
19:37
Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. check-in: 30033f96 user: drh tags: faster-analyze
19:04
Enhancements to the hex literal tests. Closed-Leaf check-in: a3cc027f user: mistachkin tags: hex-literal

Remove a surplus function prototype. #ifdef code that is not used when hex integers are omitted at compile time. check-in: a5b383e0 user: drh tags: hex-literal
13:40
Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers. This preserves backwards compatibility. Also: Throw an error on any hex literal that is too big to fit into 64 bits. check-in: 6c6f0de5 user: drh tags: hex-literal
02:07
Casting hex literals directly from string to float always results in a positive number. check-in: 4b86ccdf user: drh tags: hex-literal

When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. check-in: 48f40861 user: drh tags: trunk
20:02
Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index. Update the OR-optimization logic to make use of OP_ReopenIdx in order to avoid unnecessary cursor open requests sent to the B-Tree layer. check-in: 77f412ca user: drh tags: trunk
19:14
The optimization of check-in [b67a6e33f2] does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. check-in: eed754fe user: drh tags: trunk
16:00

2014-07-21
20:07
Limit the maximum SQLITE_MAX_ATTACHED to 127, since a signed character is sometimes used to store the database index. check-in: f1c76c7c user: drh tags: trunk
15:44
Allow the SQLITE_MAX_ATTACHED compile-time option to be larger than 62. The default limit on the number of attached databases remains 10. check-in: 1a817ae2 user: drh tags: trunk
