#  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.
#
