Changing PWD in a Builder [message #1690956]

I am now planning to implement a feature in a Builder plugin to change the working directory to a subdirectory of the workspace before launching a command. Does Launcher.ProcStarter.pwd allow going out of the workspace by using ".." or an absolute path?

If so, I must implement some protection measure not to go out of the workspace by malicious job configurations. Is there any method in Hudson that I can use to check a path is inside the workspace?

There are two security envelop

- Envelop for the user working on the Client side (UI)
- Envelop for the execution environment

The former envelop is strictly sandboxed to be with in the Hudson home. But the second envelop is open with in the execution machine restricted only by the user credentials with which Hudson itself is running or the machine in which the slave agent is running,

If so, is there any answer to the second question? I would like only to allow chdir into a subdirectory of the workspace. Since FilePath may represent remote path, absolute path checking is not so easy IMO, especially on Windows nodes.
