| ||
| 18:04 | Make the sqlite3VdbeExec() function about 2% faster by storing the opcode array in a local variable. (check-in: 8bd3cc8272 user: drh tags: trunk) | |
|
2009-11-13
| ||
| 20:52 | Performance improvements and size reductions on the OP_Seek* family of VDBE opcodes. (check-in: ed820f45cf user: drh tags: trunk) | |
| 19:43 | Simplify the OPFLG processing logic in the VDBE for a speed boost in the VDBE processing loop and a reduction in code size. (check-in: 3352b3eba5 user: drh tags: trunk) | |
| 17:36 | Start reworking fts3 code to match the rest of SQLite (code conventions, malloc-failure handling etc.). (check-in: 30a92f1132 user: dan tags: fts3-refactor) | |
| 17:05 | Force 8-byte memory alignment on memory allocated for VDBE cursors. (check-in: bdc45ba77f user: drh tags: trunk) | |
| 10:04 | Changes to test_intarray.c so that it build with SQLITE_OMIT_VIRTUALTABLE. Added testcase() macros to expr.c. (check-in: f0599d28fa user: drh tags: trunk) | |
|

| ||
| 20:39 | Shift more OP_Found opcodes over to using the unpacked format, for improved performance. (check-in: 6705ab1ad1 user: drh tags: trunk) | |
| 19:59 | Enhance the OP_Found and OP_NotFound opcodes so that they can accept an array of registers as an unpacked record in addition to a record built using OP_MakeRecord. Use this to avoid OP_MakeRecord calls during IN expression processing. (check-in: b9eab885cd user: drh tags: trunk) | |
| 17:52 | Factor out the IN operator code generation into a subroutine. Use this subroutine to implement both logic and branching versions of the IN operator. (check-in: fcff5b7e2d user: drh tags: trunk) | |
| 13:32 | Factor out the code generator for BETWEEN into a subroutine. (check-in: 5735f60b23 user: drh tags: trunk) | |
| 05:04 | Update comment for substrFunc(). Added additional SUBSTR() test cases. (check-in: d7b3801dc7 user: shaneh tags: trunk) | |
| 04:26 | Suppress unnecessary OP_Noop instructions on when the right table of a LEFT JOIN uses the index-only optimization. (check-in: e8aec08bee user: drh tags: trunk) | |
| 03:46 | Suppress excess OP_Null opcodes caused by binary IS or IS NOT operators that are converted into unary ISNULL or NOTNULL operators. (check-in: cff1b36ab2 user: drh tags: trunk) | |
| 03:13 | Adjustments to the implementation of LIMIT so that it uses fewer opcodes. (check-in: 39d5b292d2 user: drh tags: trunk) | |
|
2009-11-11
| ||
| 23:58 | If the sector size is unspecified (initially 0) then set it to 512, not to 32. (check-in: 8861b5c160 user: drh tags: trunk) | |
| 23:48 | Remove an obsolete (and incorrect) comment from sqlite3MemCompare(). No changes to code. (check-in: c15b70b3ae user: drh tags: trunk) | |
| 20:53 | Tweaks to the SUBSTR() function to make it dramatically faster in the common case where the input string is large but the 2nd and 3rd arguments are small positive integers. (check-in: 5a474a867c user: drh tags: trunk) | |
| 13:17 | Allow media sector sizes as small as 32. The former minimum size was 512. (check-in: 5a32bfc17e user: drh tags: trunk) | |
| 04:17 | Modified CLI to raise an error when extra command line options are passed. Added tests to verify correct handling, as well as other basic handling of command line options. Ticket [f5cb008a65]. (check-in: 09b4f19f10 user: shaneh tags: trunk) | |
| 01:14 | Additional test cases for the coalesce() and ifnull() functions. (check-in: d0591258b6 user: drh tags: trunk) | |
| 00:24 | Generate VDBE code for the built-in COALESCE() and IFNULL() functions. This allows unused arguments to never be evaluated, which is a performance win when the unused argument is a subquery. (check-in: 30055b257c user: drh tags: trunk) | |
|
2009-11-10
| ||
| 17:55 | Additional intarray test cases and tweaks to comments. (check-in: 0c8db5d88e user: drh tags: trunk) | |
| 17:24 | Initial implementation and test cases for the "intarray" virtual table. (check-in: 0e7d29253f user: drh tags: trunk) | |
| 17:07 | Fix for datbase name being ignored with the -batch option in the CLI. Ticket [aeff892c57]. (check-in: 8097c64acf user: shaneh tags: trunk) | |

|
2009-11-09
| ||
| 19:30 | Fix for lock structure sharing with AFP-style locking (check-in: 62f15c0aea user: adam tags: apple-osx) | |
|
2009-11-06
| ||

| 04:13 | Fix the backup API so that a backup from an empty database to a non-empty database works. Ticket [0bf974bdf9]. The only changes are in assert() statements. (check-in: ddb71cd9ed user: drh tags: trunk) | |
| 03:33 | Merged accidental fork. (check-in: d410cd4e42 user: shaneh tags: trunk) | |
| 03:22 | Add some very basic tests for the commands available from the CLI. (check-in: 6bf4333804 user: shaneh tags: trunk) | |
|

| ||
| 18:46 | Recover an ophaned branch that resulted from some ill-advised "shunning". This check-in should be identical to [bd443f39a9] except that it should be on the trunk. (check-in: 38eaf1ab6e user: drh tags: trunk) | |
| 18:31 | Fix an undefined variable on non-Mac builds. (check-in: 9552de8fb5 user: drh tags: apple-osx) | |
| 17:27 | Do not limit the trigger recursion depth when SQLITE_SMALL_STACK is defined since trigger recursion uses the heap, not the stack. (Closed-Leaf check-in: bd443f39a9 user: drh tags: shunning-error) | |
| 16:29 | Add a comment related to code coverage. No changes to code. (check-in: 6bdc2c9957 user: drh tags: shunning-error) | |
| 04:14 | Update maxRow size after shrinking the row buffer (CSV). (Closed-Leaf check-in: d474195a99 user: shaneh tags: csv_ext) | |

| 02:34 | Initial implementation of a virtual table for CSV files. (check-in: 90e63b7d84 user: shaneh tags: csv_ext) | |

| 23:02 | Fix a typo on the ynVar typedef that unfortunately caused 3.6.20 to be released with a "bug" that causes excess memory usage for Expr objects. This bug should be benign in the sense that the correct answer is still always obtained - it only uses more more memory than is really necessary. (check-in: f1c09acaca user: drh tags: shunning-error) | |
| 21:49 | Do not accept a codec no an in-memory database. (check-in: 6f3081a8e5 user: drh tags: shunning-error) | |
| 18:51 | Fix documentation typos. (check-in: 590d4ac1ee user: drh tags: shunning-error) | |
| 13:30 | Version 3.6.20 (check-in: eb7a544fe4 user: drh tags: trunk, release) | |
| 13:17 | Create a new datatype "ynVar" to hold "nVar" (number of variable) values. This is normally 16-bits can can be 32-bits if SQLITE_MAX_VARIABLE_NUMBER is large enough. (check-in: 24a4d520d5 user: drh tags: trunk) | |
| 01:56 | Report errors back up to the ATTACH command if the codec fails to initialize. (check-in: a6c696102e user: drh tags: trunk) | |

| ||
| 22:34 | Customizations for OSX contributed by Apple. (check-in: 941a01eb86 user: adam tags: apple-osx) | |
| 19:42 | Fix compiler warnings on MSVC build. (check-in: 01c4b5b84e user: shane tags: trunk) | |
| 19:18 | Enhancements to lemon to generate more compact action tables and to avoid making array bounds tests that can never fail on action table calculations. (check-in: 27d8e684db user: drh tags: trunk) | |
| 13:08 | Force all qsort() calls in mkkeywordhash.c to be stable so that we get predictable results on different platforms. (check-in: 3b02df27ab user: drh tags: trunk) | |
| 13:02 | Adjust the lemon implementation so that it always computes the same PDA regardless of qsort() implementation on the host platform. In other words, make all sorts in lemon stable. (check-in: d66a0f31eb user: drh tags: trunk) | |
