# ==== Requirements ====
#
# Verify the logic for warnings related to expire-logs-days and
# binlog-expire-logs-seconds on server start:
#
# R0. All the following shall hold with binlog disabled and binlog enabled.
#
# R1. Binlog off warnings:
#
#     R1.1. If the binary log is disabled, using any of
#           binlog-expire-logs-seconds or expire_logs_days shall
#           generate a warning.
#
#     R1.2. If the binary log is enabled, or if
#           binlog-expire-logs-seconds / expire_logs_days is not used,
#           there shall be no warning for this case.
#
# R2. Values:
#
#     R2.1. None of expire-logs-days or binlog-expire-logs-seconds is
#           set: both shall use their default values (days=0, seconds=0)
#
#     R2.2. Exactly one of expire-logs-days or binlog-expire-logs-seconds
#           is set: that value is propogated to other variable.
#
#     R2.3. Both expire-logs-days or binlog-expire-logs-seconds are
#           set, and at least one of them is set to zero: the last set value
#           should be effective and its value will be propogated to other
#           variable.
#
#     R2.4. Both expire-logs-days and binlog-expire-logs-seconds are
#           set, and both are non-zero: the last set value
#           should be effective and its value will be propogated to other
#           variable.
#
# ==== Implementation ====
#
# Test all combinations of:
#
# - log-bin: on, off
# - expire-logs-days: not set, set to 0, set to nonzero
# - binlog-expire-logs-seconds: not set, set to 0, set to nonzero
# - Verify option value propogation, by varying the order, in which options
#   are set
#      --expire_logs_days --binlog_expire_logs_seconds
#      --binlog_expire_logs_seconds --expire_logs_days
# For each such scenario, state the expected warnings and values, and
# use extra/binlog_tests/binlog_expire_warnings.inc to execute the
# scenario.
