Similar to how we treat lock files, read the contents, compare, and if they're the same don't actually write the file. Closes rust-lang#5172

LGTM, though it might be worth to consider extracting deinfo-related stuff into a separate struct
| previous[0].1 == deps { | ||
| continue | ||
| } | ||

Perhaps it's time to add a
#[derive(Eq)]
struct DepInfo { ... }
impl DepInfo {
fn parse(r: Read) -> CargoResult<Self>;
fn print(w: Write) -> CargoResult<Self>;
}it would be nice to have printing and the corresponding parsing code alongside each other.

@bors: r=matklad Makes sense! I don't think we'll be doing this too often though so I'm gonna go ahead and land for now, and we can follow up w/ an abstraction if we get more ambitious |
