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
2014-08-01
21:12
A better comment on the generated code for the NULL-in-RHS-of-IN detection logic. check-in: 9bc1c730 user: drh 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

2014-07-31
22:59
Refactoring: Change "pIndex->onError!=OE_None" to use a macro: "IsUniqueIndex(pIndex)". Easier to understand that way. check-in: e75b26ee user: drh tags: trunk
20:16
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

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

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

2014-07-23
23:57
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

15:51
Updated documentation on sqlite3_temp_directory. No changes to code. check-in: e6225a7b user: drh tags: trunk
14:52
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

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

Enhance the sqlite_stat1.stat parsing to allow additional text parameters at the end. Unrecognized parameters are silently ignored. check-in: ca2a5a2c user: drh tags: trunk

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
2014-07-19
20:15
Add new ASCII mode to the shell capable of importing and exporting using the official unit and record separators (i.e. 0x1F and 0x1E, respectively). check-in: 7fe601ea user: mistachkin tags: asciiMode

Improved documentation for checkpoints and the busy handler. No changes to code. check-in: ca92c024 user: drh tags: trunk
17:39
SQLite has long accepted some unadvertised and non-standard join syntax. Add a test to ensure that future versions continue to accept this non-standard syntax, to avoid breaking legacy applications that use the undefined syntax. check-in: 824dde7f user: drh tags: trunk

Improvements to query planning, especially in regards to estimating the cost and benefit of automatic indexes. check-in: 1272fb89 user: drh tags: trunk

Add the autoindex2.test testing module. check-in: ffe3fea4 user: drh tags: autoindex-improvements

18:35
Add the SQLITE_UNLINK_AFTER_CLOSE compile-time option. If enabled, the unlink of temporary files on unix is deferred until after the file is closed. check-in: e43a2f92 user: drh tags: trunk

Add an application ID for MBTiles tilesets. check-in: 837f6404 user: drh tags: trunk

Back out the unix VFS changes that seeks to avoid fstat() calls after an unlink(). That change did not clear the problem on FuseFS. check-in: 0617e20a user: drh tags: trunk
15:01
Add the ".eqp" dot-command to the ".help" output in the command-line shell. This was accidently omitted when the ".eqp" command was originally implemented for SQLite 3.8.4 (check-in [e6ecf7337658624]). check-in: b0b4c776 user: drh tags: trunk

Avoid an unnecessary initialization of the szFile field of unixFile in the unix VFS. check-in: 6484fb5a user: drh tags: trunk
20:24
Enhance the unix VFS so that it keeps track of the size of unlinked files internally and thus avoids the need to call fstat() on those files, since fstat() does not work reliably on unlinked files on some implementations of FuseFS. check-in: 10707d35 user: drh tags: trunk

Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list. SQLite does not use the %nonassoc directive in its grammar so this change does not affect SQLite. check-in: 1925f3a0 user: drh tags: trunk

Add a test case to ensure that estLog() works for negative numbers. check-in: 813469d9 user: drh tags: trunk
20:20
Make sure the estLog() routine in the query planner handles negative values correctly (always returning 1). Prior to this change, estLog(-1) would return a large number which could throw off the cost computations in the query planner in obscure circumstances. check-in: 75437bee user: drh tags: trunk

Fix the query planner so that it once again knows that queries without a FROM clause will never return more than one row and hence do not require sorting. check-in: 9f18b303 user: drh tags: trunk
