Probleme mit inspect.py bei Verwendung in Jython

Question

Ich verwende eine in Jython entwickelte Anwendung. Wenn ich versuche, inspect.py zu verwenden, wird eine Fehlermeldung angezeigt.

Mein Code geht so

import inspect,os,sys,pprint,imp 
def handle_stackframe_without_leak(getframe): 
    frame = inspect.currentframe() 
    try: 
     function = inspect.getframeinfo(getframe) 
     print inspect.getargvalues(getframe) 
    finally: 
     del frame 
# 
def raja(a): 
    handle_stackframe_without_leak(inspect.currentframe()) 
    print a 
# 
def callraja(): 
    handle_stackframe_without_leak(inspect.currentframe()) 
    raja("raja@ad.com") 
# 
callraja() 
raja("raja@ad.com") 
# 

Wenn ich diese mit python.exe laufen, gibt es keine Probleme gibt. Allerdings mit dieser in der App werfen die folgenden Fehler

File "C:\Program Files\jython221ondiffjava\Lib\inspect.py", line 722, in getframeinfo

Answer 1

Dies könnte http://grinder.sourceforge.net/faq.html#re-problems helfen.

Für eine schnelle Überprüfung, versuchen import re in findsource Methode (C: \ Programme \ jython221ondiffjava \ Lib \ inspect.py) Zugabe

def findsource(object): 
    """Return the entire source file and starting line number for an object. 
    (...snip...)""" 
    import re 
    file = getsourcefile(object) or getfile(object) 

etwas obwohl kann nicht versprechen, ...

Answer 2

Haben Sie versucht, Ihr Programm auf der Kommandozeile mit Jython (also außerhalb der App) zu laufen? Wenn ich Ihr Programm mit Jython 2.2.1 oder Jython 2.5.0 ausführe, erhalte ich identische Ausgabe wie von Python.
