Category: None Group: targeted for 2.2beta1 Status: Open Resolution: None Priority: 6 Submitted By: Khalid Zuberi (kzuberi) Assigned to: Nobody/Anonymous (nobody) Summary: syntax error terminates interpreter Initial Comment: On jython latest CVS, the following typo entered at the interpreter prompt: >>> x = dict[1,]) causes the interpreter to exit with a long traceback from the parser (pasted below for your entertainment). It should just be a SyntaxError. - kz java.lang.ClassCastException: org.python.parser.IdentityNode at org.python.parser.TreeBuilder.closeNode(TreeBuilder.java:426) at org.python.parser.JJTPythonGrammarState.closeNodeScope(JJTPythonGrammarState.java:138) at org.python.parser.PythonGrammar.subscriptlist(PythonGrammar.java:4129) at org.python.parser.PythonGrammar.atomtrailer(PythonGrammar.java:3728) at org.python.parser.PythonGrammar.power(PythonGrammar.java:3627) at org.python.parser.PythonGrammar.factor(PythonGrammar.java:3614) at org.python.parser.PythonGrammar.term(PythonGrammar.java:3366) at org.python.parser.PythonGrammar.arith_expr(PythonGrammar.java:3285) at org.python.parser.PythonGrammar.shift_expr(PythonGrammar.java:3204) at org.python.parser.PythonGrammar.and_expr(PythonGrammar.java:3161) at org.python.parser.PythonGrammar.xor_expr(PythonGrammar.java:3118) at org.python.parser.PythonGrammar.expr(PythonGrammar.java:3075) at org.python.parser.PythonGrammar.comparison(PythonGrammar.java:2857) at org.python.parser.PythonGrammar.not_test(PythonGrammar.java:2841) at org.python.parser.PythonGrammar.and_test(PythonGrammar.java:2751) at org.python.parser.PythonGrammar.test(PythonGrammar.java:2701) at org.python.parser.PythonGrammar.SmartTestList(PythonGrammar.java:4410) at org.python.parser.PythonGrammar.expr_stmt(PythonGrammar.java:1341) at org.python.parser.PythonGrammar.small_stmt(PythonGrammar.java:933) at org.python.parser.PythonGrammar.simple_stmt(PythonGrammar.java:884) at org.python.parser.PythonGrammar.single_input(PythonGrammar.java:254) at org.python.core.parser.doparse(parser.java:172) at org.python.core.parser.partialParse(parser.java:116) at org.python.core.Py.compile_command_flags(Py.java:1707) at org.python.util.InteractiveInterpreter.runsource(InteractiveInterpreter.java:50) at org.python.util.InteractiveInterpreter.runsource(InteractiveInterpreter.java:44) at org.python.util.InteractiveConsole.push(InteractiveConsole.java:83) at org.python.util.InteractiveConsole.interact(InteractiveConsole.java:62) at org.python.util.jython.main(jython.java:214) Traceback (innermost last): (no code object) at line 0 java.lang.IllegalArgumentException: Cannot create PyString from null! at org.python.core.PyString.<init>(PyString.java:2647) at org.python.core.PyString.<init>(PyString.java:2654) at org.python.core.PySyntaxError.<init>(PySyntaxError.java:24) at org.python.core.parser.fixParseError(parser.java:56) at org.python.core.parser.partialParse(parser.java:131) at org.python.core.Py.compile_command_flags(Py.java:1707) at org.python.util.InteractiveInterpreter.runsource(InteractiveInterpreter.java:50) at org.python.util.InteractiveInterpreter.runsource(InteractiveInterpreter.java:44) at org.python.util.InteractiveConsole.push(InteractiveConsole.java:83) at org.python.util.InteractiveConsole.interact(InteractiveConsole.java:62) at org.python.util.jython.main(jython.java:214) java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: Cannot create PyString from null! ---------------------------------------------------------------------- >Comment By: Khalid Zuberi (kzuberi) Date: 2006-08-10 12:30 Message: Logged In: YES user_id=18288 Works fine for me now.

Ok, I'll announce my debugging activities there.. ---------------------------------------------------------------------- Comment By: Frank Wierzbicki (fwierzbicki) Date: 2006-05-22 09:45 Message: Logged In: YES user_id=193969 hkarahan81, please give it a try, I don't think anyone is looking at it. The jython-dev mailing list is also a good place to announce your intentions to work on a bug, more people follow that list than watch the bug tracker. ---------------------------------------------------------------------- Comment By: Khalid Zuberi (kzuberi) Date: 2006-05-20 15:09 Message: Logged In: YES user_id=18288 Well I haven't looked into it yet myself. Assuming no-one else speaks up, i'd say go ahead. - kz ---------------------------------------------------------------------- Comment By: Hasan Karahan (hkarahan81) Date: 2006-05-20 07:06 Message: Logged In: YES user_id=1525733 I'm interested in fixing this bug, is anybody working on it at the moment? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=112867&aid=1465476&group_id=12867 |
