This is all done in 25## an effort to test for race conditions in the filesystem code. This test 26## runs until killed or Ctrl-C'd. It is suggested that it run overnight 27## with preempt turned on to make the system more sensitive to race 28## conditions. 29 30MAX_FILES=20 31CLEAR_SECS=30 32DIR="$TMPDIR/race" 33 34execute_test() 35{ 36[ -e $DIR ] || mkdir $DIR 37./fs_racer_file_create.sh $DIR $MAX_FILES & 38./fs_racer_file_create.sh $DIR $MAX_FILES & 39./fs_racer_file_create.sh $DIR $MAX_FILES & 40 41./fs_racer_dir_create.sh $DIR $MAX_FILES & 42./fs_racer_dir_create.sh $DIR $MAX_FILES & 43./fs_racer_dir_create.sh $DIR $MAX_FILES & 44 45./fs_racer_file_rename.sh $DIR $MAX_FILES & 46./fs_racer_file_rename.sh $DIR $MAX_FILES & 47./fs_racer_file_rename.sh $DIR $MAX_FILES & 48 49./fs_racer_file_link.sh $DIR $MAX_FILES & 50./fs_racer_file_link.sh $DIR $MAX_FILES & 51./fs_racer_file_link.sh $DIR $MAX_FILES & 52 53./fs_racer_file_symlink.sh $DIR $MAX_FILES & 54./fs_racer_file_symlink.sh $DIR $MAX_FILES & 55./fs_racer_file_symlink.sh $DIR $MAX_FILES & 56 57./fs_racer_file_concat.sh $DIR $MAX_FILES & 58./fs_racer_file_concat.sh $DIR $MAX_FILES & 59./fs_racer_file_concat.sh $DIR $MAX_FILES & 60 61./fs_racer_file_list.sh $DIR & 62./fs_racer_file_list.sh $DIR & 63./fs_racer_file_list.sh $DIR & 64 65./fs_racer_file_rm.sh $DIR $MAX_FILES & 66./fs_racer_file_rm.sh $DIR $MAX_FILES & 67./fs_racer_file_rm.sh $DIR $MAX_FILES & 68} 69 70 71usage() 72{ 73 echo usage: fs_racer.sh -t DURATION [Execute the testsuite for given DURATION seconds] 74 exit 0; 75} 76 77 78call_exit() 79{ 80 echo \"Cleaning up\" 81 killall fs_racer_file_create.sh 82 killall fs_racer_dir_create.sh 83 killall fs_racer_file_rm.sh 84 killall fs_racer_file_rename.sh 85 killall fs_racer_file_link.sh 86 killall fs_racer_file_symlink.sh 87 killall fs_racer_file_list.sh 88 killall fs_racer_file_concat.sh 89 rm -rf $DIR 90 exit 0 91} 92 93while getopts :t: arg 94do case $arg in 95 t) execute_test 96 sleep $OPTARG 97 call_exit;; 98 \?) usage;; 99 esac 100done 101 102exit 0 103 104
