| ||
| 16:36 | Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. file: [68fd9097] check-in: [07babb0f] user: dan branch: nulls-last, size: 160486 | |

2019-07-11
| ||
| 19:22 | Move the sqlite3VdbeSerialType() routine in-line in the OP_MakeRecord opcode. Optimizing compilers were doing this already. By doing it manually, we can omit some redundant tests and make the whole thing run a million cycles faster and use about 80 bytes less code space. file: [a2da4e67] check-in: [d837ab0d] user: drh branch: trunk, size: 159671 | |

2019-05-09
| ||
| 17:10 | Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes). This avoids corner cases of comparing integers against real values that are beyond the resolution of an IEEE 754 double. Fix for ticket [6c1d3febc00b22d457c78c2] file: [d444f4a3] check-in: [9b091527] user: drh branch: trunk, size: 158847 | |

|
2019-05-02
| ||
| 21:36 | Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. file: [326e0499] check-in: [dba836e3] user: drh branch: int-real, size: 157895 | |

| 02:26 | A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be.

| 20:39 | If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the sqlite3BtreeCursorHint() interface to provide hints to the storage engine about rows that need not be returned. 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.

2013-07-03
| ||
| 19:53 | Experimental change to the handling of foreign key constraint violations when applying a changeset: all foreign keys, immediate and deferred, are deferred until the end of the transaction (or sub-transaction) opened by the sqlite3changeset_apply(). A single call to the conflict-handler (if any) is made if any FK constraint violations are still present in the database at this point.
