# 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"); call mtr.add_suppression("Could not open .*"); -- source include/have_log_bin.inc RESET MASTER; -- let $MYSQLD_DATADIR= `select @@datadir` ############################################### # check hitting maximum file name extension: ############################################### ########## # Prepare ########## # 1.
