有什么方法可以让Mercurial给我一个更详细的错误信息吗？

Question

当Mercurial进程在本地运行时，我在远程服务器上运行钩子时遇到了问题。错误消息并不能提供很好的信息，但我很确定这是Python路径问题。当我尝试提交一个变更集时，我会得到错误。

是否有一个完整的堆栈跟踪？，下面的输出都没有堆栈跟踪那么有用。

这是常见的错误消息：

C:\workspaces\test_next>hg commit -m "test"
Exception AttributeError: "'PPReleaseProject' object has no attribute '_projectname'" in <bound method PPReleaseProject.
__del__ of <testtrack.interface.PPReleaseProject object at 0x01BE35F0>> ignored

abort: precommit.fix_in_progress hook failed

这是带有--回溯的输出：

C:\workspaces\test_next>hg --traceback commit -m "test"
Exception AttributeError: "'PPReleaseProject' object has no attribute '_projectname'" in <bound method PPReleaseProject.
__del__ of <testtrack.interface.PPReleaseProject object at 0x01C065F0>> ignored

修改钩子脚本以捕获异常(将其封装在try...except块中)，并在except子句中使用traceback模块格式化完整的跟踪并将其写入stderr/stdout？
