| 13:09 | Change the mmap_limit pragma to report the new limit, or to report the existing limit if called with no arguments. Report the default mmap_limit as part of PRAGMA compile_options. Set the default mmmap_limit to 0 for all systems other than linux, mac, windows, and solaris. (check-in: 2d9f1327fe user: drh tags: experimental-mmap) | |
| 11:52 | Remove the restriction on using xFetch to load the root pages of tables and indexes. It appears to have been based on a misconception. (check-in: 5b082efead user: dan tags: experimental-mmap) | |
| 11:38 | When moving a page to make way for the root page of a new table or index in an auto-vacuum database, save the positions of any cursors that may be holding xFetch references to the page being moved. (check-in: 9d9b1da54a user: dan tags: experimental-mmap) | |
| 11:17 | In btree.c, save the positions of other cursors open on the same table when writing via an incremental blob handle. Otherwise, they may be left holding an out-of-date xFetch page reference. (check-in: 3f09fba18f user: dan tags: experimental-mmap) | |
| 10:50 | Initialize the mmap_limit of temporary files to the configured mmap_limit. (check-in: 24bab7596b user: drh tags: experimental-mmap) | |

| 20:29 | Adjustments to mmap1.test so that it works better on windows. It still gets some answers wrong, but it no longer crashes. (check-in: ee8d3ceeec user: drh tags: experimental-mmap) | |
| 20:19 | Fix a bug in mmap2.test that was leaving an invalid sqlite3_log() callback installed, causing a crash. (check-in: c0cdaa0735 user: dan tags: experimental-mmap) | |

| 12:04 | Add test cases for errors in mmap() or mremap() is os_unix.c. (check-in: 3098a3c1e7 user: dan tags: experimental-mmap) | |
| 10:29 | Proposed template preprocessor magic for activating mmap only on platforms where we know it works. (check-in: d96272f031 user: drh tags: experimental-mmap) | |
| 01:45 | Reorder two conditions to make coverage testing easier. (check-in: 793ba4e996 user: drh tags: experimental-mmap) | |
| 00:41 | Remove an unreachable condition from pager.c. (check-in: 3628e86bf1 user: drh tags: experimental-mmap) | |
| 00:15 | Always send the SQLITE_FCNTL_MMAP_LIMIT pragma to the VFS, even if the limit is zero and even if the VFS does not support xFetch(). (check-in: 01ffdabbad user: drh tags: experimental-mmap) | |

| ||
| 22:42 | Remove a debugging printf() accidently left in the previous check-in. (check-in: 8198cdd8ac user: drh tags: experimental-mmap) | |
| 22:38 | Add the SQLITE_CONFIG_MMAP_LIMIT configuration option for overriding the SQLITE_DEFAULT_MMAP_LIMIT compile-time setting. Enhance "PRAGMA mmap_limit" so that without a specific database name, it sets the limit on all database files and changes the default for any future databases that might be added using ATTACH. (check-in: 78141d0a16 user: drh tags: experimental-mmap) | |
| 18:25 | Add a comment to xUnfetch on windows to say that the call to winUnmapfile() might be unnecessary. (check-in: e3c63c31a2 user: drh tags: experimental-mmap) | |
| 18:15 | In windows, round down the size of the memory mapped region to the next smaller multiple of the page size. (check-in: 0e44ed1bad user: drh tags: experimental-mmap) | |
| 17:58 | Merge accidental fork. (check-in: 5f4437c0e3 user: dan tags: experimental-mmap) | |
| 17:56 | Attempt to emulate mremap() on non-Linux systems by allocating a second mapping immediately following the first in virtual memory. (check-in: 4d67433db8 user: dan tags: experimental-mmap) | |
| 17:56 | Bug fix in the winMapfile() subroutine: Be sure to record the map object handle in the sqlite3_file object. (check-in: ee4d188e20 user: drh tags: experimental-mmap) | |
| 17:22 | Add xFetch and xUnfetch methods to the os_win.c VFS. (check-in: a1653a257d user: drh tags: experimental-mmap) | |

| 14:29 | Fix a problem in btree.c that could cause a crash following an OOM. (check-in: b724aa5889 user: dan tags: experimental-mmap) | |
|

| ||
| 20:32 | Change os_unix.c to use either one or two mappings internally. (check-in: e7698cba9b user: dan tags: two-mappings) | |
| 18:48 | Fix a comment in os_unix.c. No code changes. (check-in: 72813b8ec9 user: drh tags: experimental-mmap) | |
| 14:36 | Change the name of the Pager.pFree field to Pager.pMmapFreelist. (check-in: 611bd824c2 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: 30c0a69363 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: a850c7319c user: drh tags: experimental-mmap) | |

| 23:09 | Memory-mapped I/O is now on by default. The "PRAGMA mmap_limit(N)" can be used to issue a hint to the VFS to limit mmap space to N bytes. The VFS is free to ignore that hint if desired. However, if "PRAGMA mmap_limit(0)" is used, xFetch is never called. (check-in: 1b37c4effd user: drh tags: experimental-mmap) | |
| 20:50 | Add munmap and mremap to the set of os interfaces that can be overloaded in os_unix.c. (check-in: 8776047bd7 user: drh tags: experimental-mmap) | |
| 20:30 | Use mremap() on Linux. (check-in: 431aecc860 user: dan tags: experimental-mmap) | |
| 19:57 | Merge all recent trunk changes into the experimental-mmap branch. (check-in: a607d63f0b user: drh tags: experimental-mmap) | |
| 19:05 | Add a test that simulates an error in mmap(). (check-in: 6ec7367d8e user: dan tags: experimental-mmap) | |
| 18:25 | Simulate OOM errors in the sqlite3OsFetch() function. Run malloc.test as part of the "mmap" permutation. (check-in: 77443ef2cd user: dan tags: experimental-mmap) | |
| 17:00 | Change the signature of the xUnfetch method to "int (*xUnfetch)(sqlite3_file*, sqlite3_int64 iOfst, void *p)". (check-in: 115b830509 user: dan tags: experimental-mmap) | |
| 16:28 | Remove unnecessary code to round the size of a memory mapping to 4KB from os_unix.c. Rename SQLITE_IOERR_MREMAP to SQLITE_IOERR_MMAP. Fix other small issues in os_unix.c. (check-in: dce35c01a5 user: dan tags: experimental-mmap) | |
