Expand scope of the SQLITE_MAX_MMAP_SIZE define for the Win32 VFS. check-in: f4b8faab user: mistachkin tags: trunk
17:03
Refactoring the mmap interface. The controlling pragma is now "mmap_size" instead of "mmap_limit". Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms. check-in: ea1404a1 user: drh tags: trunk
