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
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-
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.
