winpdb无法使用python 3.3

Question

我不能让rpdb2与python3.3一起运行，但是根据一些来源，这应该是可能的。在

$ rpdb2 -d myscript.py
A password should be set to secure debugger client-server communication.

    handler = g_signal_handlers.get(signum, g_signal_getsignal(signum))
ValueError: signal number out of range

rpdb2的版本是RPDB 2.4.8 - Tychod。 我通过运行pip-3.3 install winpdb来安装它。在

有什么线索吗？在

Answer 1

问题的原因是rpdb2用来列出所有信号的signal模块中的扩展属性列表。新的python版本添加了一些属性，比如SIG_BLOCK, SIG_UNBLOCK, SIG_SETMASK

所以过滤也应该扩展（补丁只改变一行）：

 - rpdb2.py
+++ rpdb2.py
@@ -7278,11 +7278,11 @@
     def __set_signal_handler(self):
         """
         Set rpdb2 to wrap all signal handlers.
         """
         for key, value in list(vars(signal).items()):
-            if not key.startswith('SIG') or key in ['SIGRTMIN', 'SIGRTMAX'] or key.startswith('SIG_'):
+            if not key.startswith('SIG') or key in ['SIG_IGN', 'SIG_DFL', 'SIGRTMIN', 'SIGRTMAX']:
             continue

         handler = signal.getsignal(value)
         if handler in [signal.SIG_IGN, signal.SIG_DFL]:
             continue

不幸的是，目前还没有官方开发的winpdb或winpdb的分支，所以到目前为止，这个补丁只能存储在so上。在

今天我也遇到了同样的问题。 但我不太确定这样做是否正确。在

发件人：

def __getsignal(signum):
    handler = g_signal_handlers.get(signum, g_signal_getsignal(signum))
    return handler

该函数应位于13681行或类似行。在
