无法获取用户定义的 python gdb 命令

Question

我一直在关注 this 惊人的（视频）教程，使用 python

创建自定义用户定义的 GDB 命令

这是我的代码

import os
import gdb

class BugReport (gdb.Command):
    """Collect required info for a bug report"""

def __init__(self):
    super(BugReport, self).__init__("bugreport", gdb.COMMAND_USER)

def invoke(self, arg, from_tty):
    pagination = gdb.parameter("pagination")
    if pagination: gdb.execute("set pagination off")
    f = open("/tmp/bugreport.txt", "w")
    f.write(gdb.execute("thread apply all backtrace full", to_string=True))
    f.close()
    os.system("uname -a >> /tmp/bugreport.txt")
    if pagination: gdb.execute("set pagination on")

BugReport()

但是当我尝试在 gdb 中获取此代码时，出现以下错误：

(gdb) source mybugreport.py
Traceback (most recent call last):
  File "mybugreport.py", line 19, in <module>
    BugReport()
TypeError: function missing required argument 'name' (pos 1)

我做错了什么？

what I'm doing wrong?

Python 对缩进敏感。你想要：

class BugReport (gdb.Command):
  """Collect required info for a bug report"""

  def __init__(self):
    super(BugReport, self).__init__("bugreport", gdb.COMMAND_USER)

  def invoke(self, arg, from_tty):
    pagination = gdb.parameter("pagination")
    ...

BugReport()
