In
afpUnlock(sqlite3_file *, int)
the sharedLockByte is defined as an int (int sharedLockByte =
SHARED_FIRST+pInode->sharedByte;) although all other related variables and the
following function parameters are defined as unsigned long longs. At least
theoretically this can lead to information loss and wrong sharedLockBytes values.
If this is also practically the case I do not know.
I think it's Ok. (pInode->sharedByte) is always between 0 and
SHARED_SIZE, which is defined as 510. And SHARED_FIRST is (2^30)+2. As
you can't change either of these without creating either an incompatible
file-format or a broken build, it's probably Ok. Does look a bit odd though.
