We've got a freshly minted beta compiler, let's update to use that on nightly!
This has a few other changes associated with it as well
* A bump to the rustc version number (to 1.19.0)
* Movement of the `cargo` and `rls` submodules to their "proper" location in
`src/tools/{cargo,rls}`. Now that Cargo workspaces support the `exclude`
option this can work.
* Updates of the `cargo` and `rls` submodules to their master branches.
* Tweak to the `src/stage0.txt` format to be more amenable for Cargo version
numbers. On the beta channel Cargo will bootstrap from a different version
than rustc (e.g. the version numbers are different), so we need different
configuration for this.
* Addition of `dev` as a readable key in the `src/stage0.txt` format. If present
then stage0 compilers are downloaded from `dev-static.rust-lang.org` instead
of `static.rust-lang.org`. This is added to accomodate our updated release
process with Travis and AppVeyor.
- No more manual args manipulation -- getopts used for everything.
As a result, options can be in any position, now, even before the
subcommand.
- The additional options for test, bench, and dist now appear in the
help output.
- No more single-letter variable bindings used internally for large
scopes.
- Don't output the time measurement when just invoking 'x.py'
- Logic is now much more linear. We build strings up, and then print
them.
Now that we've also updated cargo's release process this commit also changes the
download location of Cargo from Cargos archives back to the static.r-l.o
archives. This should ensure that the Cargo download is the exact Cargo paired
with the rustc that we release.
This commit removes detection of CFG_OSTYPE and CFG_CPUTYPE from the configure
script, which means that the default value of `--build` is no longer present in
the configure script. All this logic is now available in rustbuild itself, so
there's no need to duplicate it.
Fix for bootstrapping on NixOS
NixOS puts Linux's dynamic loader in wierd place. Detect when we're on NixOS and patch the downloaded bootstrap executables appropriately.
* Update bootstrap to recognize the cputype 'sparcv9' (used on Solaris)
* Change to never use -fomit-frame-pointer on Solaris or for sparc
* Adds rust target sparcv9-sun-solaris
Fixes#39901
Automate vendoring by invoking cargo-vendor when building src dist tarballs.
This avoids #39633 bringing the `src/vendor` checked into git by #37524, past 200,000 lines of code.
I believe the strategy of having rustbuild run `cargo vendor` during the `dist src` step is sound.
However, the only way to be sure `cargo-vendor` exists is to run `cargo install --force cargo-vendor`, which will recompile it every time (not passing `--force` means you can't tell between "already exists" and "build error"). ~~This is quite suboptimal and I'd like to somehow do it in each `Dockerfile` that would need it.~~
* [ ] Cache `CARGO_HOME` (i.e. `~/.cargo`) between CI runs
* `bin/cargo-vendor` and the actual caches are the relevant bits
* [x] Do not build `cargo-vendor` all the time
* ~~Maybe detect `~/.cargo/bin/cargo-vendor` already exists?~~
* ~~Could also try to build it in a `Dockerfile` but do we have `cargo`/`rustc` there?~~
* Final solution: check `cargo install --list` for a line starting with `cargo-vendor `

I updated the beta compiler used to bootstrap the master branch in #38438 with
the intention of fixing Travis OSX linkage issues but I mistakenly forgot that
the PR only updated rustc, not Cargo itself. Cargo has a new release process
with downloads in a different location, so this commit updates rustbuild to
download from this new location by tracking revisions instead of Cargo nightly
dates.
This commit switches the default build system for Rust from the makefiles to
rustbuild. The rustbuild build system has been in development for almost a year
now and has become quite mature over time. This commit is an implementation of
the proposal on [internals] which slates deletion of the makefiles on
2016-01-02.
[internals]: https://internals.rust-lang.org/t/proposal-for-promoting-rustbuild-to-official-status/4368
This commit also updates various documentation in `README.md`,
`CONTRIBUTING.md`, `src/bootstrap/README.md`, and throughout the source code of
rustbuild itself.
Closes#37858
This allows the initial build of src/bootstrap itself to use a local
cargo taken from `configure --local-rust-root`. It was already finding
rustc this way, but was always downloading cargo since it didn't know
where to find it.
It now matches the same logic that `config.rs` will use for stage0,
where both rustc and cargo are taken from `CFG_LOCAL_RUST_ROOT`.
Vendor all rustbuild dependencies in this repo
This commit vendors all crates.io dependencies into the rust-lang/rust repository using the `cargo-vendor` tool. This is done in an effort to make rustbuild distro-ready by ensuring that our source tarballs are self-contained units which don't need extraneous network downloads.
A new `src/vendor` directory is created with all vendored crates, and Cargo, when using rustbuild, is configured to use this directory. Over time we can deduplicate this directory with the actual src tree (e.g. src/librustc_serialize, src/liblibc, src/libgetopts, ...). For now though that's left to a separate commit.
