Correct report message in jdb stdout should contain full 40 * name of the field and "access encountered" or "will be" words. 41 * The test consists of two program: 42 * watch002.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output, 43 * watch002a.java - the debugged application. 44 * COMMENTS 45 * Test fixed according to test bug: 46 * 5045859 TEST_BUG: some JDB tests do not recognize JDB prompt 47 * 48 * @library /vmTestbase 49 * /test/lib 50 * @build nsk.jdb.watch.watch002.watch002 51 * nsk.jdb.watch.watch002.watch002a 52 * @run main/othervm PropertyResolvingWrapper nsk.jdb.watch.watch002.watch002 53 * -arch=${os.family}-${os.simpleArch} 54 * -waittime=5 55 * -debugee.vmkind=java 56 * -transport.address=dynamic 57 * -jdb=${test.jdk}/bin/jdb 58 * -java.options="${test.vm.opts} ${test.java.opts}" 59 * -workdir=. 60 * -debugee.vmkeys="${test.vm.opts} ${test.java.opts}" 61 */ 62 63 package nsk.jdb.watch.watch002; 64 65 import nsk.share.*; 66 import nsk.share.jdb.*; 67 68 import java.io.*; 69 import java.util.*; 70 71 public class watch002 extends JdbTest { 72 main(String argv[])73 public static void main (String argv[]) { 74 System.exit(run(argv, System.out) + JCK_STATUS_BASE); 75 } 76 run(String argv[], PrintStream out)77 public static int run(String argv[], PrintStream out) { 78 debuggeeClass = DEBUGGEE_CLASS; 79 firstBreak = FIRST_BREAK; 80 lastBreak = LAST_BREAK; 81 compoundPromptIdent = COMPOUND_PROMPT_IDENT; 82 return new watch002().runTest(argv, out); 83 } 84 85 static final String PACKAGE_NAME = "nsk.jdb.watch.watch002"; 86 static final String TEST_CLASS = PACKAGE_NAME + ".watch002"; 87 static final String DEBUGGEE_CLASS = TEST_CLASS + "a"; 88 static final String DEBUGGEE_CLASS2 = DEBUGGEE_CLASS + "$CheckedFields"; 89 static final String FIRST_BREAK = DEBUGGEE_CLASS + ".main"; 90 static final String LAST_BREAK = DEBUGGEE_CLASS + ".breakHere"; 91 static final String COMPOUND_PROMPT_IDENT = "main"; 92 93 static String[] checkedFields = { "FS0", "FS1" }; 94 static String[] checkedFields2 = { "FP1", "FU1", "FR1", "FT1", "FV1" }; 95 runCases()96 protected void runCases() { 97 String[] reply; 98 Paragrep grep; 99 int count; 100 Vector v; 101 String found; 102 103 jdb.setBreakpointInMethod(LAST_BREAK); 104 105 reply = jdb.receiveReplyFor(JdbCommand.fields + DEBUGGEE_CLASS); 106 107 reply = jdb.receiveReplyFor(JdbCommand.fields + DEBUGGEE_CLASS2); 108 109 watchFields (DEBUGGEE_CLASS, checkedFields); 110 watchFields (DEBUGGEE_CLASS2, checkedFields2); 111 112 jdb.contToExit((checkedFields.length *2) + (checkedFields2.length *2) + 2); 113 114 reply = jdb.getTotalReply(); 115 if (!checkFields (DEBUGGEE_CLASS, reply, checkedFields)) { 116 success = false; 117 } 118 if (!checkFields (DEBUGGEE_CLASS2, reply, checkedFields2)) { 119 success = false; 120 } 121 } 122 watchFields(String className, String[] checkedFields)123 private void watchFields (String className, String[] checkedFields) { 124 String[] reply; 125 126 for (int i = 0; i < checkedFields.length; i++) { 127 reply = jdb.receiveReplyFor(JdbCommand.watch + " all " + className + "." + checkedFields[i]); 128 } 129 130 } 131 checkFields(String className, String[] reply, String[] checkedFields)132 private boolean checkFields (String className, String[] reply, String[] checkedFields) { 133 Paragrep grep; 134 String found; 135 boolean result = true; 136 int count; 137 Vector v = new Vector(); 138 139 grep = new Paragrep(reply); 140 v.add("access encountered"); 141 for (int i = 0; i < checkedFields.length; i++) { 142 v.removeAllElements(); 143 v.add("access encountered"); 144 v.add(className + "." + checkedFields[i]); 145 146 found = grep.findFirst(v); 147 if (found.length() == 0) { 148 log.complain("Failed to report access to field " + className + "." + checkedFields[i]); 149 result = false; 150 } 151 152 v.removeAllElements(); 153 v.add("will be"); 154 v.add(className + "." + checkedFields[i]); 155 156 found = grep.findFirst(v); 157 if (found.length() == 0) { 158 log.complain("Failed to report modification of field " + className + "." + checkedFields[i]); 159 result = false; 160 } 161 } 162 return result; 163 } 164 } 165
