问题描述
我正在开发的C扩展Python的广告我得到了一些设计缺陷(在开发过程中不可避免的...)。
I'm developing C extensions from python ad I obtain some segfaults (inevitable during the development...).
我在寻找一种方式来显示它在$ C $的C线的段错误发生(的想法就像是跟踪code的每一行),我该怎么做呢?
I'm searching a way to display at which line of code the segfault happens (an idea is like tracing every single line of code), how I can do that?
推荐答案
下面是一个方式来输出的Python的每一行的code运行的文件名和行号:
Here's a way to output the filename and line number of every line of Python your code runs:
import sys
def trace(frame, event, arg):
print "%s, %s:%d" % (event, frame.f_code.co_filename, frame.f_lineno)
return trace
def test():
print "Line 8"
print "Line 9"
sys.settrace(trace)
test()
输出:
call, test.py:7
line, test.py:8
Line 8
line, test.py:9
Line 9
return, test.py:9
(你可能想要写跟踪输出到文件中,当然)。
(You'd probably want to write the trace output to a file, of course.)
