Question

I would like to be able to set breakpoints to every method of a C++ class in gdb. I think the easiest way to do this is probably python, since now python has complete access to gdb. I know very little python, and with gdb on top of it, it s even harder. I am wondering if anyone knows how to write a class python code that sets breakpoints to every method of a named class in gdb.

Answer 1

假设你用伪造符号汇编成册,你甚至会为此需要花on:

rbreak source.cpp:.

Answer 2

Edit:我刚刚注意到你再次要求如何用C++这一级,而不是一个 p。 Oops。我把答案留给大家,希望它会有益于任何正在 extension延的人。

A bit of googling found: gdb操纵断点。细目:。

我们可以找到这样一类的所有方法:

import inspect
class Foo(object):
    bar = 1
    def baz(self):
        print "quoz"
inspect.getmembers(Foo, inspect.ismethod)
# [( baz , <unbound method Foo.baz>)]

齐头并进:

def stop_hammertime(klass):
    methods = inspect.getmembers(klass, inspect.ismethod)
    method_names = [klass.__name__ + m[0] for m in methods]
    return [gdb.Breakpoint(m) for m in method_names]

注:由于我没有安装<编码>gdb模块,因此没有进行测试。

Answer 3

You can generate (for example using python) a .gdbrc file with a line containing break C::foo for every function of your class C and then start gdb.
