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 30 MAX_FILES=20 31 CLEAR_SECS=30 32 DIR="$TMPDIR/race" 33 34 execute_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 71 usage() 72 { 73 echo usage: fs_racer.sh -t DURATION [Execute the testsuite for given DURATION seconds] 74 exit 0; 75 } 76 77 78 call_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 93 while getopts :t: arg 94 do case $arg in 95 t) execute_test 96 sleep $OPTARG 97 call_exit;; 98 \?) usage;; 99 esac 100 done 101 102 exit 0 103 104
