Do not allow an ALTER TABLE ADD COLUMN on a STRICT table if the added column contains a DEFAULT clause that would violate the type of the added column.

Remove some unnecessary computations from ANALYZE so that ANALYZE runs with fewer CPU cycles. These changes were spotted while working on the nearby enhanced-stat1 branch. So even if enhanced-stat1 is abandoned, that effort put into it will not have been in vain.

When inserting a 3-byte cell into a btree, ensure that the extra padding byte is 0x00. This is not necessary for security, as far as I can tell, but it seems like a reasonable precaution.

The assertion change at check-in [7946c79567b0ccd3] is insufficient to fix the problem of a Table object being deleted out from under the OP_VCheck opcode. We need to reference count the Table, which is accomplished here.

3 года назад

The original column-cache implementation from check-in [ab1edcc7fedcf279] (merged to trunk at [771fe35074b50b8d]) is unsound. This check-in fixes the issue. Had to give back a little performance, the optimization is still a overall win.

Update the documentation to the sqlite3_set_auxdata() and sqlite3_get_auxdata() routines to make it clear that they do not work as one might expect when they are called during query planning, instead of during query execution. The JSON routines misuse those interfaces, so add a special flag to JSON routines that prevents them from being invoked during query planning. Fix for the problem in [forum:/forumpost/a655ee159eca1ea5|forum post a655ee159eca1ea5].
