revno: 2630.2.20
committer: Konstantin Osipov <konstantin@mysql.com>
branch nick: mysql-6.0-runtime
timestamp: Fri 2008-06-27 20:10:42 +0400
message:
  Fix a regression introduced by WL#3726 when a table was left in the
  table cache after DROP DATABASE.
  Implementation of DROP DATABASE reads a list of files in the database
  directory and constructs from it the list of tables to be dropped.
  If the filesystem is case-insensitive and case-preserving, the
  table names should be lowercased, because the same has been done
  when entries for them were inserted into the table cache.
  Skipping this step will lead to orphaned TABLEs left in the table cache.
  Fixes lowercase_table2 failure on powermacg5.


sql/sql_db.cc:
  Lowercase the table name, it's used to construct the table cache
  key.
