    Bug#37402: Mysql cant read partitioned table with capital letter in the name · 295fc583
    Mattias Jonsson authored
    Problem was that ha_partition had HA_FILE_BASED flag set
    (since it uses a .par file), but after open it uses the first partitions
    flags, which results in different case handling for create and for
    open.
    
    Solution was to change the underlying partition name so it was consistent.
    (Only happens when lower_case_table_names = 2, i.e. Mac OS X and storage
    engines without HA_FILE_BASED, like InnoDB and Memory.)
    
    (Recommit after adding rename of check_lowercase_names to
    get_canonical_filename, and moved it from handler.h to mysql_priv.h)
    
    NOTE: if a mixed case name for a partitioned table was created when
    lower_case_table_name = 2 it should be renamed or dropped before using
    the updated version (See bug#37402 for more info)
