ska*_*ans 5 python debugging gdb deadlock python-2.7
我有一个使用 virtualenv 运行的多线程 python 应用程序，但我无法使用 gdb 正确附加到它。我想调试死锁，我认为这是我能做到的唯一方法，因为应用程序太大，我无法在开发环境中重现该问题。我已经安装python2.7-dbg，然后尝试使用gdb /home/PATHTOVENV/venv/bin/python 30183. 这是输出：

在此链接中：https://docs.python.org/devguide/gdb.html#gdb-7-and-later指出，如果您有 gdb 7 及更高版本并且想要使用 Python 扩展，则需要：
\n\n\n\n\n要激活支持，必须将包含 python-gdb.py 的目录添加到 GDB\xe2\x80\x99s \xe2\x80\x9cauto-load-safe-path\xe2\x80\x9d。将其放入 ~/.gdbinit 文件中：
\n
\nadd-auto-load-safe-path /path/to/checkout
\n 您还可以添加多个路径，以 : 分隔。
此链接中还指出：
\n\n\n\n\n您可以使用 Python 编程语言扩展 GDB。仅当使用配置 GDB 时，此功能才可用
\n--with-python。
\n GDB 使用的 Python 脚本应安装在 中data-directory/python，其中 data-directory 是 GDB 启动时确定的数据目录（请参阅数据文件）。
\n 此目录称为 python 目录，会自动添加到 Python 搜索路径中，以便允许 Python 解释器找到安装在此位置的所有脚本。
以上的配置你都正确完成了吗？
