| 18:15 | Preserve the number of requested PAGECACHE pages even if the memory pointer or size is zero. Enhance the pcache1.c header comment to explain the memory layout of a page cache line. check-in: dacb2a61 user: drh tags: trunk | |
| 15:35 | Fix a problem in the fts5 integrity-check. check-in: 4e473559 user: dan tags: trunk | |
| 11:14 | Do not preserve the btreeInitPage() results in PRAGMA integrity_check if there were cell sizing errors because PRAGMA cell_size_check was turned off during the btreeInitPage() call. check-in: 743bf1f1 user: drh tags: trunk | |
