+# BUG#34582: FLUSH LOGS does not close and reopen the binlog index
+# file
+#
+# WHAT
+# ==== 
+#
+# We want to test that FLUSH LOGS closes and reopens binlog index
+# file.
+#
+# HOW
+# === 
+#
+#  PREPARE:
+#   1. create some binlog events
+#   2. show index content, binlog events and binlog contents 
+#      for mysql-bin.000001
+#   3. copy the mysql-bin.000001 to mysql-bin-b34582.000001
+#   4. change the index file so that mysql-bin.000001 is replaced 
+#      with mysql-bin-b34582.000001
+#   5. FLUSH the logs so that new index is closed and reopened
+#
+#  ASSERTIONS:
+#   1. index file contents shows mysql-bin-b34582.000001 and 
+#      mysql-bin.000002
+#   1. show binary logs shows current index entries
+#   2. binlog contents for mysql-bin-b34582.000001 are displayed
+#   3. Purge binlogs up to the latest one succeeds
+#   4. SHOW BINARY LOGS presents the latest one only after purging
+#   5. Purged binlogs files don't exist in the filesystem
+#   6. Not purged binlog file exists in the filesystem
+#
+#  CLEAN UP:
+#   1. RESET MASTER
