Consider this check-in a proof-of-concept. It needs improvement before going on trunk. Some tests fail, but only because they new use fewer key comparisons than expected (which is a good thing!).

| 18:13 | [cbed4957] part of check-in [44e1c337] Change the MEM_Dyn flag so that it means that Mem.xDel exists and must be used to free the string or blob. Add tighter invariant checks on Mem. (check-in: [44e1c337] user: drh branch: enhanced-mem-check, size: 207253) | |

2014-02-19

| 19:14 | [b82ffb8c] part of check-in [c1e94169] 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 branch: trunk, size: 207191) | |
| 14:20 | [16c220ae] part of check-in [d2c047f3] 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: [d2c047f3] user: drh branch: trunk, size: 206514) | |

|
2014-02-16
| ||
| 01:55 | [7b74ce68] part of check-in [aa2d8b0e] 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.

|
2014-02-14
| ||
| 15:13 | [543ed4ed] part of check-in [b6bea903] 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 branch: trunk, size: 204551) | |

2014-02-12
| ||
| 21:31 | [3f0872b1] part of check-in [56bc5ce8] 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 branch: trunk, size: 203662) | |

| 23:20 | [78b41fd0] part of check-in [1e64dd78] 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: [1e64dd78] user: drh branch: trunk, size: 204518) | |
| 19:12 | [a5556442] part of check-in [e2303d1b] Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] (check-in: [e2303d1b] user: drh branch: trunk, size: 204795) | |
| 01:40 | [0944fe28] part of check-in [192dea97] 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: [192dea97] user: drh branch: trunk, size: 204790) | |
|
2014-02-07

| 13:20 | [8697f15a] part of check-in [6fb74485] 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: [6fb74485] user: drh branch: coroutine-refactor, size: 203616) | |
| 03:28 | [575189ca] part of check-in [be24fbc2] More comment updates. No changes to code. (check-in: [be24fbc2] user: mistachkin branch: trunk, size: 203116) | |

2014-02-05
| ||
| 18:15 | [2e46c464] part of check-in [2997e181] Use a new opcode, OP_OpenHash, to indicate that ephemeral tables can be unordered, rather than using the BTREE_UNORDERED bit in the P5 field. (check-in: [2997e181] user: drh branch: subquery-codegen-refactor, size: 205289) | |
| 17:08 | [361f6e55] part of check-in [a332908b] Make the root page of an ephemeral index be page 1 instead of page 2. (check-in: [a332908b] user: drh branch: subquery-codegen-refactor, size: 204978) | |

|
2014-01-21
| ||
| 22:25 | [dede894c] part of check-in [b2671e11] Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. (check-in: [b2671e11] user: drh branch: cte-via-queue, size: 204810) | |

|
2014-01-16
| ||
| 18:34 | [ccc8594e] part of check-in [a296b733] Allow only a single recursive reference in a recursive CTE. Also require that this reference is not part of a sub-query. (check-in: [a296b733] user: dan branch: common-table-expr, size: 205645) | |

| 00:59 | [bdc4a981] part of check-in [4d078147] Do not run the tool/vdbe-compress.tcl script that generates the vdbeExecUnion object that reduces the size of the sqlite3VdbeExec() stack frame unless the SQLITE_SMALL_STACK compile-time option is specified as on of the OPTS in the makefile. The vdbeExecUnion object gets in the way of C-compiler optimizer and results in slightly slower code. (check-in: [4d078147] user: drh branch: trunk, size: 204809) | |

Hints can be disabled using SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000). Cursor hints are not used by the built-in storage engine of SQLite but might be useful to applications that provide their own storage engine. The current code is work-in-progrss and contains bugs.

This is sensible and the way most platforms work in hardware. The former behavior was that oversize REALs would be cast to the smallest possible integer, -9223372036854775808, which is the way Intel hardware works.

| 16:28 | [6b15a8fb] part of check-in [6a8ad6e3] Begin a series of changes designed to reduce the scope and frequency of invalidating schemas. Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated.

This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others.

[4a1744c9]
part of check-in [8c2a0836]
Relax the locking requirements on BTree cursors. Any number of read and
write cursors can be open at the same time now, but a write cannot occur
as long as one or more read cursors are open.
Before this change, one or more read cursors could be open on a table, or a single write cursor, but not both. Both policies have the same desirable effect: they prevent writes to a table while a sequential scan of that table is underway. But the new policy is a little less restrictive. Both policies prevent an UPDATE from occurring inside a SELECT (which is what we want) but the new policy allows a SELECT to occur inside an UPDATE.
