# The main test is innodb.foreign_key. This is an additional test that
# the maximum length cannot be exceeded for implicitly created
# constraint names. On Microsoft Windows, MAX_PATH is a much stricter
# limit than the 255-byte maximum path component length on many other systems,
# including Linux and IBM AIX.

CREATE TABLE t (a INT PRIMARY KEY) ENGINE=InnoDB;

# The maximum identifier length is 64 characters.
# my_charset_filename will expand some characters to 5 characters,
# e.g., # to @0023.
# Many operating systems (such as Linux) or file systems
# limit the path component length to 255 bytes,
# corresponding to the 51 characters below: 5*51=255.
