Fixed a bug : if you called DROP DATABASE for a database on which there simultaneously were running queries, the MySQL server could crash or hang. Crashes fixed, but a full fix has to wait some changes in the MySQL layer of code.
Fixed a bug : on Windows one had to put the database name in lower case for DROP DATABASE to work. Fixed in 3.23.49: case no longer matters on Windows. On Unix the database name remains case-sensitive.
Fixed a bug : if one defined a non-latin1 character set as the default character set, then definition of foreign key constraints could fail in an assertion failure in dict0crea.c, reporting an internal error 17.
