Slightly smaller and faster by allocating Parser objects on the stack. check-in: 436a89b9 user: drh tags: trunk
19:53
Split the OP_Last opcode into OP_Last and OP_SeekEnd. Use OP_SeekEnd to position a cursor prior to appending. Ticket [cb91bf4290c211d]. check-in: 3e02474c user: drh tags: trunk
14:16

16:42
Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening. This prevents the names from getting mangled by query transformations, and obviates hacks in the query flattener that attempt to work around the name mangling.

16:01
Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening.

16:42
In sqlite3_bind_pointer(), invoke the destructor if the bind index is out of range, like sqlite3_bind_blob() does. Closed-Leaf check-in: d6684d2a user: drh tags: pointer-with-destructor

12:27
Add the pointer-type parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a static string that must match (according to strcmp()) or else the pointer is passed as a NULL. This is a security measure to prevent crossing pointers between different extensions. check-in: e1196567 user: drh tags: branch-3.20
11:39

20:33
Fix a register allocation problem in PRAGMA integrity_check that caused the same register to be used for two different purposes on the first ATTACHed database if the schema for the ATTACHed database was noticable more complex than the schema for the first database.
