Changes In Branch cumulative-progress-count Excluding Merge-Ins
This is equivalent to a diff from 1589db012e to 7a62fc6abc
|
2017-02-21
| ||
| 15:27 | Very small enhancement to dispatch speed for SQL functions. (check-in: 3c3228ed16 user: drh tags: trunk) | |
| 14:04 | The VDBE cycle counts for the sqlite3_progress_handler() callback are now cumulative. Leftovers from the previous statement are applied to the next statement. (Leaf check-in: 7a62fc6abc user: drh tags: cumulative-progress-count) | |
| 13:29 | Proof of concept for a "PRAGMA vdbe_cycle_limit=N" command. When N>0, invoke sqlite3_interrupt() whenever any byte code program uses more than N virtual machine cycles. (Leaf check-in: 9626b41e6e user: drh tags: vdbe_cycle_limit) | |

2017-02-20
| ||
| 23:32 | Correct a harmless typo in the previous check-in. (check-in: 1589db012e user: mistachkin tags: trunk) | |
| 19:13 | Avoid unsigned integer overflows for SQLITE_WIN32_HEAP_INIT_SIZE when the Win32 heap subsystem is used with very large values of SQLITE_DEFAULT_CACHE_SIZE and/or SQLITE_DEFAULT_PAGE_SIZE. (check-in: 96b6a98e5e user: mistachkin tags: trunk) | |
