7176479: G1: JVM crashes on T5-8 system with 1.5 TB heap
Summary: Refactor G1's hot card cache and card counts table into their own files. Simplify the card counts table, including removing the encoding of the card index in each entry. The card counts table now has a 1:1 correspondence with the cards spanned by heap. Space for the card counts table is reserved from virtual memory (rather than C heap) during JVM startup and is committed/expanded when the heap is expanded. Changes were also reviewed-by Vitaly Davidovich.

# @test # @bug 6888954 # @summary exercise HotSpot error handling code # @author John Coomes # @run shell vmerrors.sh # Repeatedly invoke java with a command-line option that causes HotSpot to # produce an error report and terminate just after initialization. Each # invocation is identified by a small integer, <n>, which provokes a different # error (assertion failure, guarantee failure, fatal error, etc.). The output # from stdout/stderr is written to <n>.out and the hs_err_pidXXX.log file is # renamed to <n>.log. # # The automated checking done by this script is minimal. When updating the # fatal error handler it is more useful to run it manually or to use the -retain # option with the jtreg so that test directories are not removed automatically. # To run stand-alone: # # TESTJAVA=/java/home/dir # TESTVMOPTS=... # export TESTJAVA TESTVMOPTS # sh test/runtime/6888954/vmerrors.sh ulimit -c 0 # no core files i=1 rc=0 assert_re='(assert|guarantee)[(](str|num).*failed: *' guarantee_re='guarantee[(](str|num).*failed: *' fatal_re='fatal error: *' signal_re='(SIGSEGV|EXCEPTION_ACCESS_VIOLATION).* at pc=' tail_1='.*expected null' tail_2='.*num=' for re in \ "${assert_re}${tail_1}" "${assert_re}${tail_2}" \ "${guarantee_re}${tail_1}" "${guarantee_re}${tail_2}" \ "${fatal_re}${tail_1}" "${fatal_re}${tail_2}" \ "${fatal_re}.*truncated" "ChunkPool::allocate" \ "ShouldNotCall" "ShouldNotReachHere" \ "Unimplemented" "$signal_re" do i2=$i [ $i -lt 10 ] && i2=0$i "$TESTJAVA/bin/java" $TESTVMOPTS -XX:+IgnoreUnrecognizedVMOptions \ -XX:ErrorHandlerTest=${i} -version > ${i2}.out 2>&1 # If ErrorHandlerTest is ignored (product build), stop. # # Using the built-in variable $! to get the pid does not work reliably on # windows; use a wildcard instead. mv hs_err_pid*.log ${i2}.log || exit $rc for f in ${i2}.log ${i2}.out do egrep -- "$re" $f > $$ if [ $? -ne 0 ] then echo "ErrorHandlerTest=$i failed ($f)" rc=1 fi done rm -f $$ i=`expr $i + 1` done exit $rc
