[Scons-users] detecting invalid command actions

[Tom Tanner (BLOOMBERG/ LONDON)]

we have a check currently in our scons which checks that executor.get_contents() doesn't contain an absolute path to a users git clone, as this rather destroys the caching.

This isn't very satisfactory though, obviously, because it's a change that has to be merged whenever we get a new scons.

Is there some more portable way I can attach a check to every action to ensure they don't have inappropriate absolute paths lurking?
