| ||
| 20:44 | Further changes to sqlite3VdbeRecordCompare(). (check-in: 5708937400 user: dan tags: experimental) | |
|
2014-02-25
| ||
| 21:01 | Attempt to speed up sqlite3VdbeRecordCompare() by various means. This code is in an interim state. (check-in: 85206e0bba user: dan tags: experimental) | |
| 18:12 | Also adjust the order of files in the amalgamation to ensure that _FILE_OFFSET_BITS is defined before any #include, for QNX. (check-in: 23001a85cd user: drh tags: trunk) | |
| 14:52 | QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. (check-in: 953cdd6ada user: drh tags: trunk) | |
|
2014-02-24
| ||
| 21:42 | Fix several small style/consistency issues with the previous check-in. (check-in: 2477b3a294 user: mistachkin tags: trunk) | |
| 21:20 | Enhance testing support for the Win32 VFS dynamic extension loading facilities. (check-in: 53081e7202 user: mistachkin tags: trunk) | |
| 19:49 | Close some stray connections in walro.test. (check-in: d6746cabaa 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: ba5f0a5599 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: 4df0ac9023 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: b46d4e8923 user: drh tags: trunk) | |
| 19:32 | Fix a harmless shadowed-variable warning. (check-in: 824029090d user: drh tags: trunk) | |
| 19:23 | Make sure that the difference between two string pointers is passed into sqlite3_mprintf() as type "int". (check-in: d5d973fedc 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: c1e94169dd user: drh tags: trunk) | |
| 14:20 | Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. (check-in: d2c047f304 user: drh tags: trunk) | |
| 01:31 | Make sure a multi-row VALUES clause works correctly in a compound SELECT. (check-in: 85b355cfb4 user: drh tags: trunk) | |
| 00:53 | Tweaks in support of VDBE branch test coverage. (check-in: b978256469 user: drh tags: trunk) | |
|
2014-02-18
| ||
| 11:31 | Fix VDBE branch accounting on comparison operators. (check-in: b287520c92 user: drh tags: trunk) | |
| 03:07 | Add VdbeCoverage() and VdbeCoverageIf() macros for improved VDBE coverage testing. (check-in: b92d31a97d user: drh tags: trunk) | |
| 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: 915f6f1c7a 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: a72687699b user: drh tags: trunk) | |
| 22:40 | Add logic to do test coverage measurements on the VDBE code. (Closed-Leaf check-in: ce184c7bb1 user: drh tags: insert-optimization) | |
| 15:40 | Add a test case for OP_SoftNull. (check-in: f29d194e03 user: drh tags: insert-optimization) | |
| 15:36 | Merge the VDBE_PROFILE fixes from trunk. (check-in: 2914e41911 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: 35b4d6e938 user: drh tags: insert-optimization) | |
| 01:13 | Fix the VDBE_PROFILE logic. Add a script to process the output file. (check-in: 7adb3da235 user: drh tags: trunk) | |
|
2014-02-16
| ||
| 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: aa2d8b0e81 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: e07a32f308 user: drh tags: trunk) | |
| 20:59 | Reduce the number of cases where it is necessary to check for NULL after the loop terminating condition. (check-in: 3c1ae447de 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: b6bea903ac user: drh tags: trunk) | |
| 00:25 | Revise how the Tcl system encoding is handled by the test suite. (check-in: 9e573198e1 user: mistachkin tags: trunk) | |
|
2014-02-13
| ||
| 21:57 | Improvements to the makefile and README for MSVC. (check-in: b22b614068 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: 48c821fd97 user: dan tags: trunk) | |
| 19:10 | Change README to README.md and expand it. Remove unrelated and obsolete files. (check-in: 18d4e258c4 user: drh tags: trunk) | |
| 18:46 | Avoid passing a flags argument with the internal WAL_SYNC_TRANSACTIONS bit set when calling sqlite3OsSync(). (check-in: e3b79e920c user: dan tags: trunk) | |
| 13:42 | Update the tclconfig files to the latest from http://core.tcl.tk/tclconfig. (check-in: b81ba7a4bc user: drh tags: trunk) | |
|
2014-02-12
| ||
| 23:52 | Minor simplifications to the "zeroPage()" routine in btree.c. (check-in: cc8f10bcb2 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: 56bc5ce895 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: 5d01426ddf user: drh tags: trunk) | |
|
2014-02-11
| ||
| 16:24 | Increase the version number to 3.8.4 (check-in: 0a8bcbbd4e 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: f5ad1e1bf2 user: drh tags: trunk) | |
| 14:37 | Fixes to the "editline" support in the command-line shell. (check-in: 7989ce5f10 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: c950d6c411 user: drh tags: trunk) | |
|
2014-02-10
| ||
| 21:07 | Fix a pointless conditional. Add a test case. (check-in: 9367632dd7 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: fe284afe73 user: drh tags: memdb-warning) | |
| 19:36 | On unix, make the "transient in-memory database" text bold, but not red. Leave the text read on windows. (check-in: c9eba2f7be user: drh tags: memdb-warning) | |
| 19:27 | In the command-line shell, on the banner, warn about the use of a transient in-memory database in bold red text. (check-in: 0fbc0fcec1 user: drh tags: memdb-warning) | |
| 18:56 | Fix the compound-select-to-subquery converter so that it works with the new compound-select object linkage introduced as part of the fix for ticket [31a19d11b97088296]. (check-in: 572d4be4db user: drh tags: trunk) | |
| 16:13 | Modify the command-line shell to print a warning when using an in-memory database. (check-in: 90e9deae4a user: drh tags: memdb-warning) | |
| 15:56 | Improvements to a "Synopsis:" comment in the VDBE engine. (check-in: 0dfa7ee915 user: drh tags: trunk) | |
| 12:59 | Faster implementation for sqlite3MulInt64(). (check-in: 010c48f671 user: drh tags: trunk) | |
| 03:21 | Faster and smaller implementation of sqlite3_value_type(). (check-in: 5708bc24b8 user: drh tags: trunk) | |
|
2014-02-09
| ||
| 23:59 | Add a compound-query test to the speedtest1 test program. (check-in: 5329957591 user: drh tags: trunk) | |
| 18:02 | Use the WITH clause to help resolve names for SELECT statements on the left of a compound query. Proposed fix for ticket [31a19d11b97088296a]. (check-in: 67bfd59d90 user: drh tags: trunk) | |
| 00:52 | Add the Mandelbrot Set testcase to the "cte" testset of speedtest1. (check-in: 56febbeb57 user: drh tags: trunk) | |
| 00:18 | Add a new "testset" to the speedtest1 program: The sudoku solver. (check-in: 4677ef2f8a user: drh tags: trunk) | |
|
2014-02-08
| ||
| 23:20 | Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. (check-in: 1e64dd782a user: drh tags: trunk) | |
| 19:12 | Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] (check-in: e2303d1b0c user: drh tags: trunk) | |
| 13:24 | Fix a harmless compiler warning in VS2013. (check-in: 83116ee3e0 user: drh tags: trunk) | |
| 13:22 | Fix a harmless compiler warning in VS2013. (check-in: 35f2793db5 user: drh tags: branch-3.8.3) | |
| 13:12 | Tweaks to the generated VDBE code to make it a little easier to follow. (check-in: 129217ee91 user: drh tags: trunk) | |
| 04:24 | Enable constant expression factoring even if no tables are read and no transaction is started. (check-in: a45b87713c user: drh tags: trunk) | |
| 01:40 | Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. (check-in: 192dea9731 user: drh tags: trunk) | |
|
2014-02-07
| ||
| 22:21 | Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the need for separate boolean registers to record when a co-routine has finished. (check-in: 5a88b6a7ae user: drh tags: trunk) | |
| 19:33 | Fix redundant definitions of _LARGE_FILE and _LARGEFILE_SOURCE. (check-in: 4043d87979 user: drh tags: trunk) | |
| 19:26 | In the TCL bindings, make sure Tcl_AppendResult() is always terminated by "(char*)0" and not just "0". (check-in: ea4d23d1c0 user: drh tags: trunk) | |
| 19:18 | Change the OP_InitCoroutine instruction to jump over the co-routine implementation. (Closed-Leaf check-in: a522f364a6 user: drh tags: coroutine-refactor) | |
| 18:27 | Get rid of the OP_Undef and OP_IsUndef opcodes in favor of higher-level OP_InitCoroutine and OP_EndCoroutine. (check-in: 1ec0e9dd4b user: drh tags: coroutine-refactor) | |
| 13:20 | Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. (check-in: 6fb7448550 user: drh tags: coroutine-refactor) | |
| 03:28 | More comment updates. No changes to code. (check-in: be24fbc221 user: mistachkin tags: trunk) | |

| 23:56 | Delete the OP_VerifySchema opcode. Enhance OP_Transaction to do the schema version checks that OP_VerifySchema used to do. (check-in: 2f3376ebf1 user: drh tags: trunk) | |
| 13:18 | Change the spellfix1 virtual table to deterministically names its shadow tables. (check-in: 5219cdfc56 user: drh tags: trunk) | |
| 02:46 | Add additional error messages and a progress spinner to the ".clone" command. (check-in: dd0db3f0ce user: drh tags: trunk) | |

| 11:05 | In the Win32 VFS, the winSysInfo variable should be static. (check-in: 4a4dd371a7 user: mistachkin tags: trunk) | |
|
2014-02-04
| ||
| 23:45 | Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. (check-in: f2504089df user: drh tags: trunk) | |
| 20:46 | Remove the SF_Materialize flag from the SELECT object as it does not accomplish anything useful. (check-in: 65d5dcddbd user: drh tags: trunk) | |
| 15:55 | Rearrange fields in the Parse object for a tighter packing, resulting in an 8% size reduction on x64. (check-in: 3e1a3f68d7 user: drh tags: trunk) | |

| 14:04 | Provide hints to the btree layer Next and Previous primitives to let them know if they can be no-ops if the underlying index is unique. (check-in: 6c643e45c2 user: drh tags: trunk) | |
| 13:52 | Version 3.8.3 (check-in: e816dd9246 user: drh tags: trunk, release, version-3.8.3) | |
