0fbb50ee15 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.

b483eba051 Ensure that when the source of a backup is a database that is zero bytes in size, the final destination database consists of at least one page. Truncating it to zero bytes is equivalent to zeroing the schema cookie and change counter, which can cause problems for existing clients.

SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many

and since there really isn't any need to turn that optimization off.
