14 check-ins using file src/btree.c version f5ea8d3d

2013-03-25
19:05
Add a test that simulates an error in mmap(). (check-in: 6ec7367d 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: 77443ef2 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: 115b8305 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: dce35c01 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: bbcaab3e 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: 5885ba6c 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: 1431be95 user: dan tags: experimental-mmap)
17:29
Improve a comment in wal.c. No code changes. (check-in: 60b9f5e4 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: 8dbe89d0 user: dan tags: experimental-mmap)
12:15
In the winMremap VFS function, unmap the region prior to attempting to truncate the file. (check-in: 8870c4cc 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: f57a9c91 user: mistachkin tags: experimental-mmap)
09:56
Preliminary changes to support the xMremap VFS method on Windows. (check-in: 75a85a1c user: mistachkin tags: experimental-mmap)
2013-03-22
20:15
Update wal mode tests so that they work with the mmap test permutation. (check-in: f7295872 user: dan tags: experimental-mmap)
19:56
Fix a potential NULL-pointer dereference in btreeSwapOutMmap(). (check-in: e81ccdcd user: drh tags: experimental-mmap)
