# === Purpose ===
# Check PURGE BINARY LOGS operation is mutually exclusive with BACKUP lock.
#
# === Requirements ===
# R1. PURGE BINARY LOGS must be mutually exclusive when
# LOCK INSTANCE FOR BACKUP statement is executed.
#
# === Implementation ===
#
# 1. Create database and tables
# 2. Create second connection
# 2.1. Execute PURGE BINARY LOGS but stop it on a sync point
# 3. Use first connection
# 3.1. Check LOCK INSTANCE FOR BACKUP cannot proceed
# 4. Use second connection
# 4.1. Finish PURGE BINARY LOGS
# 5. Check LOCK INSTANCE FOR BACKUP can proceed
# 6. Cleanup
#
# === References ===
#
# Bug#35342521 Binary log purge should hold IX backup lock
