Python：如何检测调试解释器 [英] Python: How to detect debug interpreter

问题描述

如果我的python脚本是由调试解释器（即python_d.exe而不是python.exe）运行的，我该如何检测？我需要改变路径到一些我传递给扩展名的DLL。

How can I detect in my python script if its being run by the debug interpreter (ie python_d.exe rather than python.exe)? I need to change the paths to some dlls that I pass to an extension.

例如，我喜欢在我的python脚本开始时做这样的事情：

eg Id like to do something like this at the start of my python script:

#get paths to graphics dlls
if debug_build:
    d3d9Path   = "bin\\debug\\direct3d9.dll"
    d3d10Path  = "bin\\debug\\direct3d10.dll"
    openGLPath = "bin\\debug\\openGL2.dll"
else:
    d3d9Path   = "bin\\direct3d9.dll"
    d3d10Path  = "bin\\direct3d10.dll"
    openGLPath = "bin\\openGL2.dll"

我想到在扩展中添加一个IsDebug（）方法，如果它是是调试版本（即使用#define DEBUG构建），否则为false。但是，这似乎是一件事情，我确信我可以让python告诉我...

I thought about adding an "IsDebug()" method to the extension which would return true if it is the debug build (ie was built with "#define DEBUG") and false otherwise. But this seems a bit of a hack for somthing Im sure I can get python to tell me...

推荐答案

Distutils使用 sys.gettotalrefcount 来检测调试python构建：

Distutils use sys.gettotalrefcount to detect a debug python build:

# ...
if hasattr(sys, 'gettotalrefcount'):
   plat_specifier += '-pydebug'

• 此方法不依赖在可执行文件名称' * _ d.exe '。它适用于任何名称。


• 此方法是跨平台的。它不依赖于' _d.pyd '后缀。


• this method doesn't rely on an executable name '*_d.exe'. It works for any name.
• this method is cross-platform. It doesn't depend on '_d.pyd' suffix.
