有没有办法让 Mercurial 给我更详细的错误消息？

Question

当 Mercurial 进程在本地运行时，我的钩子在远程服务器上运行时遇到问题。错误消息信息不是很丰富，但我很确定这是一个 Python 路径问题。当我尝试提交变更集时出现错误。

有没有办法获得完整的堆栈跟踪？以下输出都没有堆栈跟踪那么有用。

这是常规错误消息：

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 --traceback 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

修改您的钩子脚本以捕获异常（将其包装在 try... except 块中），并在 except 子句中使用 traceback 模块格式化全长回溯并将其写出到 stderr/stdout？
