Functionality added or changed:
libmysqld.c is now 1024*1024*1024.
When sending a too big packet to the server with the not compressed protocol, the client now gets an error message instead of a lost connection.
We now send big queries/result rows in bigger hunks, which should give a small speed improvement.
Fixed some bugs with the compressed protocol for rows > 16MB.
InnoDB tables now also support
UPDATE CASCADE in
constraints. See the
InnoDB section in the
manual for the
Fixed bug in
ALTER TABLE with
Fixed core dump bug in
Fixed a bug in handling communication packets bigger than 16MB. Unfortunately this required a protocol change; If you upgrade the server to 4.0.8 and above and have clients that use packets >= 255*255*255 bytes (=16581375) you must also upgrade your clients to at least 4.0.8. If you don't upgrade, the clients hang when sending a big packet.
Fixed bug when sending blobs longer than 16MB to client.
Fixed bug in
GROUP BY when used on BLOB
Fixed a bug in handling
NULL values in
