1 # @test 2 # @bug 6888954 3 # @summary exercise HotSpot error handling code 4 # @author John Coomes 5 # @run shell vmerrors.sh 6 7 # Repeatedly invoke java with a command-line option that causes HotSpot to 8 # produce an error report and terminate just after initialization. Each 9 # invocation is identified by a small integer, <n>, which provokes a different 10 # error (assertion failure, guarantee failure, fatal error, etc.). The output 11 # from stdout/stderr is written to <n>.out and the hs_err_pidXXX.log file is 12 # renamed to <n>.log. 13 # 14 # The automated checking done by this script is minimal. When updating the 15 # fatal error handler it is more useful to run it manually or to use the -retain 16 # option with the jtreg so that test directories are not removed automatically. 17 # To run stand-alone: 18 # 19 # TESTJAVA=/java/home/dir 20 # TESTVMOPTS=... 21 # export TESTJAVA TESTVMOPTS 22 # sh test/runtime/6888954/vmerrors.sh 23 24 ulimit -c 0 # no core files 25 26 i=1 27 rc=0 28 29 assert_re='(assert|guarantee)[(](str|num).*failed: *' 30 bad_func_re='SIGSEGV.* at pc=0x00*0f,' 31 guarantee_re='guarantee[(](str|num).*failed: *' 32 fatal_re='fatal error: *' 33 signal_re='(SIGSEGV|EXCEPTION_ACCESS_VIOLATION).* at pc=' 34 tail_1='.*expected null' 35 tail_2='.*num=' 36 37 for re in \ 38 "${assert_re}${tail_1}" "${assert_re}${tail_2}" \ 39 "${guarantee_re}${tail_1}" "${guarantee_re}${tail_2}" \ 40 "${fatal_re}${tail_1}" "${fatal_re}${tail_2}" \ 41 "${fatal_re}.*truncated" "ChunkPool::allocate" \ 42 "ShouldNotCall" "ShouldNotReachHere" \ 43 "Unimplemented" "$signal_re" \ 44 "$bad_func_re" 45 46 do 47 i2=$i 48 [ $i -lt 10 ] && i2=0$i 49 50 "$TESTJAVA/bin/java" $TESTVMOPTS -XX:+IgnoreUnrecognizedVMOptions \ 51 -XX:ErrorHandlerTest=${i} -version > ${i2}.out 2>&1 52 53 # If ErrorHandlerTest is ignored (product build), stop. 54 # 55 # Using the built-in variable $! to get the pid does not work reliably on 56 # windows; use a wildcard instead. 57 mv hs_err_pid*.log ${i2}.log || exit $rc 58 59 for f in ${i2}.log ${i2}.out 60 do 61 egrep -- "$re" $f > $$ 62 if [ $? -ne 0 ] 63 then 64 echo "ErrorHandlerTest=$i failed ($f)" 65 rc=1 66 fi 67 done 68 rm -f $$ 69 70 i=`expr $i + 1` 71 done 72 73 exit $rc
