From: drh Date: Mon, 25 Mar 2013 23:09:28 +0000 (+0000) Subject: Memory-mapped I/O is now on by default. The "PRAGMA mmap_limit(N)" can be X-Git-Tag: version-3.7.17~114^2~39 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0d0614bdc6e59c1cb52bc79fdf8dafbbc78f57f9;p=thirdparty%2Fsqlite.git 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.
