# Bug#30102: rename table does corrupt tables with partition files on failure
# This test case renames the table such that the partition file name 
# is 255 chars long. Due the restriction of 260 char path name (including drive label)
# this will fail in windows.
# Other tests related to this bug can be found in partition_not_embedded.test
