Added a new callback response for iso_xmit handlers: RAW1394_ISO_AGAIN.

This would be returned when the callback doesn't have enough data to create a complete packet. This can occur when the xmit buffers are bigger than the buffers supplying the data. It is not nescessarily an error, because there are enough packets in the xmit buffer. This response could give the data supplyer more time to fill the intermediate buffer without losing any packets.

Peter McGoron 2-1/+73 SQLite allows for UNIONs and INTERSECTIONs between SELECT statements, but it does not support grouping them. By recursively applying DeMorgan's laws, the parser can reduce the parse tree to only * Literals * NOT literals (i.e. "all items not belonging to this tag") * ANDs * ORs What SQLite /can/ do is have SELECT statements come from other SELECT statements. A query like (X & Y & Z) | (A & B & C) in pseudo-SQLite becomes SELECT * FROM ( SELECT * FROM tbl WHERE name IN X INTERSECTION SELECT * FROM tbl WHERE name IN Y INTERSECTION SELECT * FROM tbl WHERE name IN Z ) UNION SELECT * FROM ( SELECT * FROM tbl WHERE name IN A INTERSECTION SELECT * FROM tbl WHERE name IN B INTERSECTION SELECT * FROM tbl WHERE name IN C ) One future optimization would be to group all literals at a certain level with each other, so that there are less direct queries to the entire tag table. 2021-07-26queryparse: use demorgan's laws to simplify parsed expression
