| 18:39 | Modify VFilter and VRename to use registers instead of the vdbe stack for inputs. (CVS 4670) (check-in: 253ed40aa3 user: danielk1977 tags: trunk) | |
| 18:03 | Registers (aka memory cells) in the VM are now numbered starting with 1 instead of 0. A register number of 0 means "no such register". (CVS 4669) (check-in: 0b849805c3 user: drh tags: trunk) | |
| 17:31 | Modify OP_VUpdate to read arguments from a range of memory cells instead of from the stack. (CVS 4668) (check-in: 955b15a020 user: danielk1977 tags: trunk) | |
| 11:50 | Change the VdbeOp.p4 union to include specific pointer types for the various values of VdbeOp.p4type. (CVS 4667) (check-in: 7e8330c804 user: danielk1977 tags: trunk) | |
| 09:51 | Change the OP_Insert opcode to read the key and data to insert from memory cells, not the stack. (CVS 4666) (check-in: 46501f490a user: danielk1977 tags: trunk) | |
| 08:18 | Change the output of vdbe_trace etc. to include operands p3 and p5. (CVS 4665) (check-in: 76f2040b05 user: danielk1977 tags: trunk) | |
| 08:08 | Combine the OP_Column and OP_DfltValue opcodes. (CVS 4664) (check-in: c30f820635 user: danielk1977 tags: trunk) | |
| 07:54 | Change OP_OpenRead and OP_OpenWrite so that the database number is read from the P3 operand, not the stack. (CVS 4663) (check-in: 35da261daf user: danielk1977 tags: trunk) | |
| 07:09 | Fix EXPLAIN and EXPLAIN query plan to work with new opcode format. (CVS 4662) (check-in: b166c33a7b user: danielk1977 tags: trunk) | |
| 01:28 | Revamp sqlite3VdbeAddOpList() so that the structure holds integer values for P1, P2, and P3. (CVS 4661) (check-in: 4dc507d87b user: drh tags: trunk) | |
| 00:01 | Refactoring the VM. The P3 parameter is changed to P4. A P5 parameter is added (though not currently used.) Add routines sqlite3VdbeAddOpX() where X is one of 0, 1, 2, 3, or 4. (CVS 4660) (check-in: 027875e4d4 user: drh tags: trunk) | |

| 17:25 | Add operands p4 and p5 to the VdbeOp structure. (CVS 4659) (check-in: ad528735e4 user: drh tags: trunk) | |
| 17:11 | Minor optimizations for sub-selects in EXISTS(...) expressions: Discard any DISTINCT or ORDER BY clauses and do not calculate any column values. (CVS 4658) (check-in: fbd17a8976 user: danielk1977 tags: trunk) | |
| 16:27 | Combine the eDest and iParm arguments to sqlite3Select() into a single type - "SelectDest". (CVS 4657) (check-in: 86dcdfe6d7 user: danielk1977 tags: trunk) | |
| 14:28 | Add opcodes OP_ResultRow and OP_RegMakeRec which are register-based equivalents to OP_Callback and OP_MakeRecord. Use the new opcodes. (CVS 4656) (check-in: 4c7f35da77 user: drh tags: trunk) | |
| 13:05 | Remove a surplus OP_Close from delete.c. Fixes a problem with (4654). (CVS 4655) (check-in: 03cc91b3b0 user: drh tags: trunk) | |
| 11:50 | Take advantage of the fact that b-tree cursors need not be closed while other cursors modify their tables to simplify trigger program generation code. (CVS 4654) (check-in: f1966a8a47 user: danielk1977 tags: trunk) | |
| 04:41 | Add some extra tests for the recent trigger compilation optimization. (CVS 4653) (check-in: de54dad800 user: danielk1977 tags: trunk) | |
| 00:34 | Begin setting a foundation on which to convert the VM from a stack-based to a register-based machine. Everything is still mostly stack based with this check-in. This change merely begins adding infrastructure to support a register-based architecture. (CVS 4652) (check-in: 051ec01f27 user: drh tags: trunk) | |
|

| 05:49 | Define SQLITE_CORE=1 at the start of the amalgamation file for the benefit of any extension source code (i.e. fts3) appended to it. Ticket #2858. (CVS 4649) (check-in: 6dea8c1638 user: danielk1977 tags: trunk) | |

|
2007-12-29
| ||
| 13:39 | Add experimental pragma "quick_check", a reduced version of integrity_check that runs without most of the overhead of the full integrity_check. (CVS 4645) (check-in: 2ddc8d7272 user: danielk1977 tags: trunk) | |
| 13:18 | Mem3.c enhanced so that an allocation of N bytes only requires (N+11)&~7 bytes instead of (N+15)&~7 bytes of heap storage. Minimum heap usage per allocation is still 16 bytes. 8-byte alignment is preserved. (CVS 4644) (check-in: d027f91cea user: drh tags: trunk) | |
|
2007-12-27
| ||

|
2007-12-21
| ||
| 04:47 | Fix for #2854. "BEGIN EXCLUSIVE" excludes other shared cache users from using the database. (CVS 4642) (check-in: 2e59b1d07e user: danielk1977 tags: trunk) | |
| 00:02 | Fix some issues with lemon. Tickets #2852 and #2835. (CVS 4641) (check-in: 5283e0d146 user: drh tags: trunk) | |

|
2007-12-18
| ||

|
2007-12-17
| ||
| 16:20 | When SQLITE_MAX_SQL_LENGTH is 0, disable the limit. Make the default 0. Once again build the sqlite3 CLI from individual source files so that it can be built on systems that lack tclsh. Tickets #2845 and #2846. (CVS 4636) (check-in: 07aeca3b9c user: drh tags: trunk) | |
