Fixes#4326
`cargo package` (and so `cargo publish`) parses a crate’s `Cargo.toml`,
makes some modifications, and re-serializes it.
Because the `TomlManifest` struct uses `HashMap`
with its default `RandomState` hasher,
the maps’ iteration order changed on every run.
As a result, when using `cargo vendor`,
updating a dependency would generate a diff larger than necessary,
with non-significant order-changes obscuring significant changes.
This replaces some uses of `HashMap` with `BTreeMap`,
whose iteration order is deterministic (based on `Ord`).
Convert CargoResult, CargoError into an implementation provided by error-chain. The previous is_human machinery is mostly removed; now errors are displayed unless of the Internal kind, verbose mode will print all errors.
This commit migrates Cargo as much as possible from rustc-serialize to
Serde. This not only provides an excellent testing ground for the toml
0.3 release but it also is a big boost to the speed of parsing the JSON
bits of the registry.
This doesn't completely excise the dependency just yet as docopt still
requires it along with handlebars. I'm sure though that in time those
crates will migrate to serde!
This is a shared directory among multiple Cargo processes so access to it needs
to be properly synchronized. This commit changes the API of `Config::target_dir`
and then propagates the changes outward as necessary.
One fallout of this change is now we allow release/debug builds to proceed in
parallel.
This commit tweaks some metadata here and there to publish Cargo on crates.io.
* License fields are added to Cargo.tomls
* `registry` was renamed to `crates-io`
* API docs for the `cargo` crate are now generated via `make doc`
