2014-02-26
21:35
More efficient removal of duplicates in recursive queries using the UNION compound operator. check-in: 06c2db87 user: drh tags: trunk
13:53
In the command-line shell for CSV import, if the lines are \r\n terminated and the last field is blank, make sure an empty string and not a "\r" string is imported. check-in: 9c2e7612 user: drh tags: trunk
02:26
Improved handling of constants and especially constant functions in the ORDER BY clause of a query. Do not optimize out "ORDER BY random()". Fix for ticket [65bdeb9739605cc2296]. check-in: dca1945a user: drh tags: trunk
2014-02-25
21:55

Also adjust the order of files in the amalgamation to ensure that _FILE_OFFSET_BITS is defined before any #include, for QNX. check-in: 23001a85 user: drh tags: trunk
14:52
QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. check-in: 953cdd6a user: drh tags: trunk
2014-02-24
21:42
Fix several small style/consistency issues with the previous check-in. check-in: 2477b3a2 user: mistachkin tags: trunk

19:49
Close some stray connections in walro.test. check-in: d6746cab user: dan tags: trunk
19:07
In memsys5, initialize new allocations to non-zero bytes. Change the content of freed allocations to prevent use after free. These changes in SQLITE_DEBUG only. check-in: ba5f0a55 user: drh tags: trunk
14:24
Remove an unused variable from the VDBE_PROFILE compile-time option. Keep the opcode count in an u32 instead of an int. check-in: 4df0ac90 user: drh tags: trunk
2014-02-20
19:42
Fix the text of a comment used to generate VDBE opcode documentation so that it omits symbols that can be mistaken for a hyperlink by the parser. check-in: b46d4e89 user: drh tags: trunk

2014-02-19
19:14
Add the VdbeCoverageNeverTaken() macro, and comments that better describe how the VDBE branch coverage measurement works. Add some tags to provide 100% VDBE branch coverage. check-in: c1e94169 user: drh tags: trunk
14:20
Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL.

01:07
Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools. check-in: 915f6f1c user: drh tags: trunk
2014-02-17
23:52
Merge in performance enhancements for INSERT operations, especially INSERTs on tables that have no affinity columns or that have many indices or INSERTs with content coming from a SELECT. Add the SQLITE_TESTCTRL_VDBE_COVERAGE test control and the SQLITE_VDBE_COVERAGE compile-time option used for measure coverage of branches in VDBE programs. check-in: a7268769 user: drh tags: trunk
22:40
Add logic to do test coverage measurements on the VDBE code. Closed-Leaf check-in: ce184c7b user: drh tags: insert-optimization
15:40
Add a test case for OP_SoftNull. check-in: f29d194e user: drh tags: insert-optimization
15:36
Merge the VDBE_PROFILE fixes from trunk. check-in: 2914e419 user: drh tags: insert-optimization
14:59
Avoid unnecessary calls to applyAffinity() during INSERT and UPDATE operations, especially for table that have indices and tables for which all columns have affinity "NONE". check-in: 35b4d6e9 user: drh tags: insert-optimization
01:13
Fix the VDBE_PROFILE logic. Add a script to process the output file. check-in: 7adb3da2 user: drh tags: trunk
2014-02-16
19:20
Use the modern MinGW major version macro, not the deprecated one. Closed-Leaf check-in: 057c16ee user: mistachkin tags: mingw4x
01:55
Enhance the code generator for INSERT INTO ... SELECT so that the SELECT generates output directly in the registers that INSERT INTO will be using, in many cases, and OP_SCopy operations can thus be avoided. check-in: aa2d8b0e user: drh tags: insert-optimization
2014-02-14
23:49
Seek past NULLs in a top-constrained search. Avoid checking for NULLs in the body of the search. check-in: e07a32f3 user: drh tags: trunk
23:35
Better support for MinGW 4.x. check-in: e1472307 user: mistachkin tags: mingw4x
20:59
Reduce the number of cases where it is necessary to check for NULL after the loop terminating condition. check-in: 3c1ae447 user: drh tags: trunk
15:13
Add OP_IdxGT and OP_IdxLE as distinct opcodes. Formerly these operations where done using OP_IdxGE and OP_IdxLT with the P5 flag set. But VDBE code is easier to read with distinct opcode names. Also change OP_SeekGe to OP_SeekGE, and so forth, so that the capitalization is consistent. The whole point of this change is to improve the readability of VDBE listings. check-in: b6bea903 user: drh tags: trunk
00:25
Revise how the Tcl system encoding is handled by the test suite. check-in: 9e573198 user: mistachkin tags: trunk
2014-02-13
21:57
Improvements to the makefile and README for MSVC. check-in: b22b6140 user: mistachkin tags: trunk
19:27
Ensure that if the "psow=0" URI option or FCNTL_POWERSAFE_OVERWRITE file-control is used to clear the power-safe overwrite flag, extra padding frames are added to the WAL file. check-in: 48c821fd user: dan tags: trunk
19:10
Change README to README.md and expand it. Remove unrelated and obsolete files. check-in: 18d4e258 user: drh tags: trunk
18:46
Avoid passing a flags argument with the internal WAL_SYNC_TRANSACTIONS bit set when calling sqlite3OsSync(). check-in: e3b79e92 user: dan tags: trunk
13:42
Update the tclconfig files to the latest from http://core.tcl.tk/tclconfig. check-in: b81ba7a4 user: drh tags: trunk
2014-02-12
23:52
Minor simplifications to the "zeroPage()" routine in btree.c. check-in: cc8f10bc user: drh tags: trunk
21:31
Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. check-in: 56bc5ce8 user: drh tags: trunk
14:43
Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Fix for ticket [c34d0557f740c45070]. check-in: 5d01426d user: drh tags: trunk
2014-02-11
16:24
Increase the version number to 3.8.4 check-in: 0a8bcbbd user: drh tags: trunk
16:22
Updates to the command-line shell. Simplify the banner message. Add the ".save" command as an alias for ".backup". When starting with no arguments, include a banner message warning that the database is transient and in-memory and mention the ".open" command. check-in: f5ad1e1b user: drh tags: trunk
14:37
Fixes to the "editline" support in the command-line shell. check-in: 7989ce5f user: drh tags: trunk
01:50
Make sure that virtual WHERE-clause terms do not get transformed into real terms when processing set of OR-connected terms. Fix for ticket [4c86b126f22ad]. check-in: c950d6c4 user: drh tags: trunk
2014-02-10
21:07
Fix a pointless conditional. Add a test case. check-in: 9367632d user: drh tags: trunk
19:59
Add the ".save" command as an alias for ".backup". Improvements to the way font changes are implemented on the in-memory database warning. Closed-Leaf check-in: fe284afe user: drh tags: memdb-warning
