| 17:03 | [480a6d255c] part of check-in [ea1404a10a] 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.

[8024b87635]
part of check-in [8c2a083698]
Relax the locking requirements on BTree cursors. Any number of read and
write cursors can be open at the same time now, but a write cannot occur
as long as one or more read cursors are open.
Before this change, one or more read cursors could be open on a table, or a single write cursor, but not both. Both policies have the same desirable effect: they prevent writes to a table while a sequential scan of that table is underway. But the new policy is a little less restrictive. Both policies prevent an UPDATE from occurring inside a SELECT (which is what we want) but the new policy allows a SELECT to occur inside an UPDATE.

| 00:24 | [d40fa46c8c] part of check-in [8a98466711] Fix a bug in DROP TABLE that could cause SQLITE_MASTER table corruption. The root problem was that the sequence of BTree operations (Delete, Next) would not always leave the cursor pointing at the first entry after the entry that was deleted. A consequence of this error was that a DROP TABLE on a table with indices would not always remove every index associated with that table from the SQLITE_MASTER table. Subsequent attempts to open the database will fail when the index for the missing table was parsed. Changes have also been made to ignore extra indices in the SQLITE_MASTER table so that a database previously corrupted by this bug is once again readable.
