# BUG#40611: MySQL cannot make a binary log after sequential number beyond
# unsigned long.
#
# Problem statement
# =================
#
# Extension for log file names might be created with negative
# numbers (when counter used would wrap around), causing server
# failure when incrementing -00001 (reaching number 000000
# extension).
#
# Test
# ====
# This tests aims at testing the a patch that removes negatives
# numbers from log name extensions and checks that the server
# reports gracefully that the limit has been reached.
#
# It instruments index file to point to a log file close to
# the new maximum and calls flush logs to get warning.
#
call mtr.add_suppression("Next log extension: 2147483647. Remaining log filename extensions: 0.");
call mtr.add_suppression("Log filename extension number exhausted:");
call mtr.add_suppression("Can't generate a unique log-filename");
