Strive to use posix_fallocate() rather than ftruncate() when posix_fallocate() is available. Ticket [5eaa61ea18]. (check-in: 29980b08 user: drh tags: trunk)
11:08
Use preprocessor macros to automatically detect whether or not posix_allocate() is available. (It is generally available on Linux but not on Mac.) Ticket [5eaa61ea1881040b17449ca043b6f8fd9ca55dc3] (Closed-Leaf check-in: 597333f1 user: drh tags: tkt-5eaa61ea18)
10:54
When available, use posix_fallocate() rather than ftruncate() to allocate space for mmap()ed -shm files, since posix_fallocate() gives an error if no disk space is available whereas ftruncate() is silent and leaves the system vulnerable to a SIGBUS upon first write to the mmap()ed region. Ticket [5eaa61ea1881040b17449ca043b6f8fd9ca55dc3] (check-in: 35625961 user: drh tags: tkt-5eaa61ea18)

01:27
Merge the latest changes from trunk: chiefly the outer/inner loop query optimizer scoring enhancement and the INSTR() function. (check-in: 2993ca20 user: drh tags: sessions)
2012-11-09
21:40
Only log unlink() errors if the error is something other than SQLITE_IOERR_DELETE_NOENT. The error is still reported up the stack, it is simply not added to the sqlite3_log(). (check-in: 5a3b07f0 user: drh tags: trunk)
20:17
Change os_unix.c to propagate ENOENT errors back to sqlite as SQLITE_IOERR_DELETE_NOENT. Have SQLite ignore these where they are benign and propagate them back to the caller where they may indicate a file-system malfunction of some description. (check-in: bed9c172 user: dan tags: trunk)
