| 20:32 | Change os_unix.c to use either one or two mappings internally. check-in: e7698cba user: dan tags: two-mappings | |
| 14:36 | Change the name of the Pager.pFree field to Pager.pMmapFreelist. check-in: 611bd824 user: drh tags: experimental-mmap | |
| 14:16 | In btree.c, save the positions of any open cursors before moving any pages around to auto-vacuum the database on commit. check-in: 30c0a693 user: dan tags: experimental-mmap | |
| 01:07 | Previous check-in accidently left mmap turned off by default. This checkin fixes that. Unfortunately, shared.test is now segfaulting. All other veryquick tests appear to work, however. check-in: a850c731 user: drh tags: experimental-mmap | |
