# === Purpose ===
#
# This test verifies that `PURGE BINARY LOGS TO` purges the binlog files
# that have been moved to another location and their absolute path is
# listed in the binlog index file.
#
# === Implementation ===
#
# 1. Generate binary logs.
# 2. Move the binary logs to the tmp dir.
# 3. Generate a new index file having the absolute path of the binlogs.
# 4. Verify that `PURGE BINARY LOGS TO` purges the binlogs which are
#    not in the data directory.
#
# === References ===
# Bug #28284624	`PURGE BINARY LOGS TO` FAILS WHEN BINARY LOG SPECIFIED
#               IS NOT IN BINLOG BASE DIR
