| 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) | |
| 14:31 | Do not return SQLITE_IOERR when the user attempts to open a small file that is not a database with mmap enabled. Instead return SQLITE_NOTADB. (check-in: bbcaab3e80 user: dan tags: experimental-mmap) | |
| 13:50 | Fix a case in the pager where an xFetch() reference was being leaked following an OOM error. (check-in: 5885ba6ce7 user: dan tags: experimental-mmap) | |
|
2013-03-23
| ||
| 21:00 | Replace the sqlite3_io_methods.xMremap interface with sqlite3_io_methods.xFetch and xUnfetch. (check-in: 1431be9557 user: dan tags: experimental-mmap) | |
| 17:29 | Improve a comment in wal.c. No code changes. (check-in: 60b9f5e4dd user: dan tags: experimental-mmap) | |
| 14:20 | Fix a case where a checkpoint operation could write to an invalid part of a memory mapped region. (check-in: 8dbe89d05c user: dan tags: experimental-mmap) | |
| 12:15 | In the winMremap VFS function, unmap the region prior to attempting to truncate the file. (check-in: 8870c4cc6c user: mistachkin tags: experimental-mmap) | |
| 10:09 | Do not unmap the mapped file region in winTruncate as there may be outstanding pointers to it. (check-in: f57a9c91e9 user: mistachkin tags: experimental-mmap) | |
| 09:56 | Preliminary changes to support the xMremap VFS method on Windows. (check-in: 75a85a1c6a user: mistachkin tags: experimental-mmap) | |
|

| ||
| 20:15 | Update wal mode tests so that they work with the mmap test permutation. (check-in: f7295872a3 user: dan tags: experimental-mmap) | |
| 19:56 | Fix a potential NULL-pointer dereference in btreeSwapOutMmap(). (check-in: e81ccdcd87 user: drh tags: experimental-mmap) | |
| 19:17 | Fix a case where the mapped part of a database file may be written during a backup operation. (check-in: c8d67aefff user: dan tags: experimental-mmap) | |
| 18:20 | Allow the database file to be memory mapped in wal mode. (check-in: d190ddabc3 user: dan tags: experimental-mmap) | |
| 17:46 | Add a fix for the assert() statements added by the previous commit. (check-in: 19345416ed user: dan tags: experimental-mmap) | |
| 08:58 | Add assert statements to os_unix.c to ensure that any mapped region of the database file is not being read or written using the xRead() or xWrite() methods. (check-in: 765615f9fb user: dan tags: experimental-mmap) | |
|
2013-03-21
| ||
| 20:39 | Fix cases where xRead() was being used to read from a memory mapped part of the database file. (check-in: 5c9e9df27b user: dan tags: experimental-mmap) | |
| 20:00 | Avoid calling xRead() on a part of the database file that is memory mapped. (check-in: c8eac290a7 user: dan tags: experimental-mmap) | |
| 15:57 | Fix a problem when opening a write-transaction while there exist read-only b-tree cursors in mmap mode. (check-in: 32e0bbb736 user: dan tags: experimental-mmap) | |
| 14:47 | Do not use the Linux mremap() call. Use the same strategy for xMremap() as on OSX instead. (check-in: 5ed8ad780c user: dan tags: experimental-mmap) | |
