# ==== Purpose ====
#
# The purpose of this test is to ensure that GTID_PURGED variable is
# properly set when binlogs need to be purged by means of
# `expire_logs_days` usage during server startup process.
#
# ==== Requirements ====
#
# R1. When `expire_logs_days` has been expired upon server
#     restart, binary logs should be purged and GTID_PURGED should be updated
#     accordingly.
#
# ==== Implementation ====
#
# TC1. Restart the server with simulated `expire_logs_days` expiration
# ---------------------------------------------------------------------------
# 1. Create a table.
# 2. Stop the server.
# 3. Start the server with `--expire-logs-days` sinthetically set to
#    expire.
# 4. Ensure GTID_PURGED is set at the correct value.
# 5. Ensure that we have only one binary log file.
#
# TC2. Restart the server with simulated `expire_logs_days`
#      expiration and after flush
# ----------------------------------------------------------------
# 1. Create a table.
# 2. Flush the logs.
# 3. Insert a row.
# 4. Stop the server.
# 5. Start the server with `--expire-logs-days` sinthetically set to
#    expire.
# 6. Ensure GTID_PURGED is set at the correct value.
# 7. Ensure that we have only one binary log file.
