[Jython-dev] Current test failures in modjy.

[Alan K. <jyt...@xh...>]

Hi all,

I've just started to do a code review of modjy, and wanted to make a
couple of small tweaks. Before changing anything, I quickly ran the
unittests, and got 9 failures, all caused by the same thing. The stack
trace is given below.

Two odd things are

1. The failure seems to occur whenever an attempt is made to import
the $py.class file containing a class definition and a function
definition. The failure relates to wrapping the function, even when
the function is not involved in the test. I.e. the root cause of the
exception is

java.lang.NoSuchMethodError:
org.python.core.Py.makeClass(Ljava/lang/String;[Lorg/python/core/PyObject;Lorg/python/core/PyCode;Lorg/python/core/PyObject;)Lorg/python/core/PyObject;

2. Looking down the stack trace, I can see that each invocation is
synchronized, even though it should not be. You can see this by the
presence of

     [java]     at
org.python.modules.synchronize$SynchronizedCallable.__call__(synchronize.java:72)

In the stack traces.

Any idea why this is failing? I don't know what revision introduced the error.

Why are the calls being synchronized?

I'm running these tests on Windows Server 2003.

Regards,

Alan.

Here is the stack trace of one of the failures: all 9 are the same.
