winpdb没有使用python 3.3

我无法让rpdb2与python 3.3一起运行,而根据多个来源,这应该是可行的。

$ rpdb2 -d myscript.py

rpdb2的版本是RPDB 2.4.8 - Tychod。 我是通过运行pip-3.3 install winpdb安装它的。

任何线索?

今天遇到同样的问题这就是我为它工作所做的事情。 我仍然不太确定这样做是否正确。

自:

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

要:

def __getsignal(signum):
    try:
        # The problems come from the signum which was 0.
        g_signal_getsignal(signum)
    except ValueError:
        return None
    handler = g_signal_handlers.get(signum, g_signal_getsignal(signum))
    return handler

此功能应位于 13681 等行。

问题的原因是signal模块中的扩展属性列表,rpdb2使用该列表列出所有信号。新的python版本添加了SIG_BLOCK, SIG_UNBLOCK, SIG_SETMASK

等属性

所以过滤也应该扩展(补丁只改变一行):

--- rpdb2.py
+++ rpdb2.py

     def __set_signal_handler(self):
         """

+            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,目前没有官方开发或winpdb的分支,所以现在这个补丁只会存储在SO上。
