rustbuild: Vendor all dependencies 

This commit vendors all dependencies when using rustbuild to ensure that we
don't hit the network during a build and can build as a self-contained unit.

//! A build dependency for running `cmake` to build a native library
//!
//! This crate provides some necessary boilerplate and shim support for running
//! the system `cmake` command to build a native library. It will add
//! appropriate cflags for building code to link into Rust, handle cross
//! compilation, and use the necessary generator for the platform being
//! targeted.
//!
//! The builder-style configuration allows for various variables and such to be
//! passed down into the build as well.
//!
//! ## Installation
//!
//! Add this to your `Cargo.toml`:
//!
//! ```toml
//! [build-dependencies]
//! cmake = "0.1"
//! ```
//!
//! ## Examples
//!
//! ```no_run
//! use cmake;
//!
//! // Builds the project in the directory located in `libfoo`, installing it
//! // into $OUT_DIR
//! let dst = cmake::build("libfoo");
//!
//! println!("cargo:rustc-link-search=native={}", dst.display());
//! println!("cargo:rustc-link-lib=static=foo");
//! ```
//!
//! ```no_run
//! use cmake::Config;
//!
//! let dst = Config::new("libfoo")
//! .define("FOO", "BAR")
//! .cflag("-foo")
//! .build();
//! println!("cargo:rustc-link-search=native={}", dst.display());
//! println!("cargo:rustc-link-lib=static=foo");

//! A logger configured via an environment variable which writes to standard
//! error.
//!
//! ## Example
//!
//! ```
//! #[macro_use] extern crate log;
//! extern crate env_logger;
//!
//! use log::LogLevel;
//!
//! fn main() {
//! env_logger::init().unwrap();
//!
//! debug!("this is a debug {}", "message");
//! error!("this is printed by default");
//!
//! if log_enabled!(LogLevel::Info) {
//! let x = 3 * 4; // expensive computation
//! info!("the answer was: {}", x);
//! }
//! }
//! ```
//!
//! Assumes the binary is `main`:
//!
//! ```{.bash}
//! $ RUST_LOG=error ./main
//! ERROR:main: this is printed by default
//! ```
//!
//! ```{.bash}
//! $ RUST_LOG=info ./main
//! ERROR:main: this is printed by default
//! INFO:main: the answer was: 12
//! ```
//!
//! ```{.bash}
//! $ RUST_LOG=debug ./main
//! DEBUG:main: this is a debug message
//! ERROR:main: this is printed by default
//! INFO:main: the answer was: 12
//! ```
//!
//! You can also set the log level on a per module basis:
//!
//! ```{.bash}
//! $ RUST_LOG=main=info ./main
//! ERROR:main: this is printed by default
//! INFO:main: the answer was: 12
//! ```
//!
//! And enable all logging:
//!
//! ```{.bash}
//! $ RUST_LOG=main ./main
//! DEBUG:main: this is a debug message
//! ERROR:main: this is printed by default
//! INFO:main: the answer was: 12
//! ```
//!
//! See the documentation for the log crate for more information about its API.
//!
//! ## Enabling logging
//!
//! Log levels are controlled on a per-module basis, and by default all logging
//! is disabled except for `error!`. Logging is controlled via the `RUST_LOG`
//! environment variable. The value of this environment variable is a
//! comma-separated list of logging directives. A logging directive is of the
//! form:
//!
//! ```text
//! path::to::module=log_level
//! ```
//!
//! The path to the module is rooted in the name of the crate it was compiled
//! for, so if your program is contained in a file `hello.rs`, for example, to
//! turn on logging for this file you would use a value of `RUST_LOG=hello`.
//! Furthermore, this path is a prefix-search, so all modules nested in the
//! specified module will also have logging enabled.
//!
//! The actual `log_level` is optional to specify. If omitted, all logging will
//! be enabled. If specified, it must be one of the strings `debug`, `error`,
//! `info`, `warn`, or `trace`.
//!
//! As the log level for a module is optional, the module to enable logging for
//! is also optional. If only a `log_level` is provided, then the global log
//! level for all modules is set to this value.
//!
//! Some examples of valid values of `RUST_LOG` are:
//!
//! * `hello` turns on all logging for the 'hello' module
//! * `info` turns on all info logging
//! * `hello=debug` turns on debug logging for 'hello'
//! * `hello,std::option` turns on hello, and std's option logging
//! * `error,hello=warn` turn on global error logging and also warn for hello
//!
//! ## Filtering results
//!
//! A RUST_LOG directive may include a regex filter. The syntax is to append `/`
//! followed by a regex. Each message is checked against the regex, and is only
//! logged if it matches. Note that the matching is done after formatting the
//! log string but before adding any logging meta-data. There is a single filter
//! for all modules.
//!
//! Some examples:
//!
//! * `hello/foo` turns on all logging for the 'hello' module where the log
//! message includes 'foo'.
//! * `info/f.o` turns on all info logging where the log message includes 'foo',
//! 'f1o', 'fao', etc.
//! * `hello=debug/foo*foo` turns on debug logging for 'hello' where the log
//! message includes 'foofoo' or 'fofoo' or 'fooooooofoo', etc.
//! * `error,hello=warn/[0-9] scopes` turn on global error logging and also
//! warn for hello. In both cases the log message must include a single digit
//! number followed by 'scopes'.

# gcc-rs
A library to compile C/C++ code into a Rust library/application.
[![Build Status](https://travis-ci.org/alexcrichton/gcc-rs.svg?branch=master)](https://travis-ci.org/alexcrichton/gcc-rs)
[![Build status](https://ci.appveyor.com/api/projects/status/onu270iw98h81nwv?svg=true)](https://ci.appveyor.com/project/alexcrichton/gcc-rs)
[Documentation](http://alexcrichton.com/gcc-rs)
A simple library meant to be used as a build dependency with Cargo packages in
order to build a set of C/C++ files into a static archive. Note that while this
crate is called "gcc", it actually calls out to the most relevant compile for
a platform, for example using `cl` on MSVC. That is, this crate does indeed work
on MSVC!
## Using gcc-rs
First, you'll want to both add a build script for your crate (`build.rs`) and
also add this crate to your `Cargo.toml` via:
```toml
[package]
# ...
build = "build.rs"
[build-dependencies]
gcc = "0.3"
```
Next up, you'll want to write a build script like so:
```rust,no_run
// build.rs
extern crate gcc;
fn main() {
gcc::compile_library("libfoo.a", &["foo.c", "bar.c"]);
}
```
And that's it! Running `cargo build` should take care of the rest and your Rust
application will now have the C files `foo.c` and `bar.c` compiled into it. You
can call the functions in Rust by declaring functions in your Rust code like so:
```
extern {
fn foo_function();
fn bar_function();
}
pub fn call() {
unsafe {
foo_function();
bar_function();
}
}
fn main() {
// ...
}
```
## External configuration via environment variables
To control the programs and flags used for building, the builder can set a
number of different environment variables.
* `CFLAGS` - a series of space separated flags passed to "gcc". Note that
individual flags cannot currently contain spaces, so doing
something like: "-L=foo\ bar" is not possible.
* `CC` - the actual C compiler used. Note that this is used as an exact
executable name, so (for example) no extra flags can be passed inside
this variable, and the builder must ensure that there aren't any
trailing spaces. This compiler must understand the `-c` flag. For
certain `TARGET`s, it also is assumed to know about other flags (most
common is `-fPIC`).
* `AR` - the `ar` (archiver) executable to use to build the static library.
Each of these variables can also be supplied with certain prefixes and suffixes,
in the following prioritized order:
1. `<var>_<target>` - for example, `CC_x86_64-unknown-linux-gnu`
2. `<var>_<target_with_underscores>` - for example, `CC_x86_64_unknown_linux_gnu`
3. `<build-kind>_<var>` - for example, `HOST_CC` or `TARGET_CFLAGS`
4. `<var>` - a plain `CC`, `AR` as above.
If none of these variables exist, gcc-rs uses built-in defaults
In addition to the the above optional environment variables, `gcc-rs` has some
functions with hard requirements on some variables supplied by [cargo's
build-script driver][cargo] that it has the `TARGET`, `OUT_DIR`, `OPT_LEVEL`,
and `HOST` variables.
[cargo]: http://doc.crates.io/build-script.html#inputs-to-the-build-script
## Optional features
Currently gcc-rs supports parallel compilation (think `make -jN`) but this
feature is turned off by default. To enable gcc-rs to compile C/C++ in parallel,
you can change your dependency to:
```toml
[build-dependencies]
gcc = { version = "0.3", features = ["parallel"] }
```
By default gcc-rs will limit parallelism to `$NUM_JOBS`, or if not present it
will limit it to the number of cpus on the machine.
## Compile-time Requirements
To work properly this crate needs access to a C compiler when the build script
is being run. This crate does not ship a C compiler with it. The compiler
required varies per platform, but there are three broad categories:
* Unix platforms require `cc` to be the C compiler. This can be found by
installing gcc/clang on Linux distributions and Xcode on OSX, for example.
* Windows platforms targeting MSVC (e.g. your target triple ends in `-msvc`)
require `cl.exe` to be available and in `PATH`. This is typically found in
standard Visual Studio installations and the `PATH` can be set up by running
the appropriate developer tools shell.
* Windows platforms targeting MinGW (e.g. your target triple ends in `-gnu`)
require `gcc` to be available in `PATH`. We recommend the
[MinGW-w64](http://mingw-w64.org) distribution, which is using the
[Win-builds](http://win-builds.org) installation system.
You may also acquire it via
[MSYS2](http://msys2.github.io), as explained [here][msys2-help]. Make sure
to install the appropriate architecture corresponding to your installation of
rustc. GCC from older [MinGW](http://www.mingw.org) project is compatible
only with 32-bit rust compiler.
[msys2-help]: http://github.com/rust-lang/rust#building-on-windows
## C++ support
`gcc-rs` supports C++ libraries compilation by using the `cpp` method on
`Config`:
```rust,no_run
extern crate gcc;
fn main() {
gcc::Config::new()
.cpp(true) // Switch to C++ library compilation.
.file("foo.cpp")
.compile("libfoo.a");
}
```
When using C++ library compilation switch, the `CXX` and `CXXFLAGS` env
variables are used instead of `CC` and `CFLAGS` and the C++ standard library is
linked to the crate target.
## License
`gcc-rs` is primarily distributed under the terms of both the MIT license and
the Apache License (Version 2.0), with portions covered by various BSD-like
licenses.
See LICENSE-APACHE, and LICENSE-MIT for details.

//! A library for build scripts to compile custom C code
//!
//! This library is intended to be used as a `build-dependencies` entry in
//! `Cargo.toml`:
//!
//! ```toml
//! [build-dependencies]
//! gcc = "0.3"
//! ```
//!
//! The purpose of this crate is to provide the utility functions necessary to
//! compile C code into a static archive which is then linked into a Rust crate.
//! The top-level `compile_library` function serves as a convenience and more
//! advanced configuration is available through the `Config` builder.
//!
//! This crate will automatically detect situations such as cross compilation or
//! other environment variables set by Cargo and will build code appropriately.
//!
//! # Examples
//!
//! Use the default configuration:
//!
//! ```no_run
//! extern crate gcc;
//!
//! fn main() {
//! gcc::compile_library("libfoo.a", &["src/foo.c"]);
//! }
//! ```
//!
//! Use more advanced configuration:
//!
//! ```no_run
//! extern crate gcc;
//!
//! fn main() {
//! gcc::Config::new()
//! .file("src/foo.c")
//! .define("FOO", Some("bar"))
//! .include("src")
//! .compile("libfoo.a");
//! }
//! ```

libc
====
A Rust library with native bindings to the types and functions commonly found on
various systems, including libc.
[![Build Status](https://travis-ci.org/rust-lang/libc.svg?branch=master)](https://travis-ci.org/rust-lang/libc)
[![Build status](https://ci.appveyor.com/api/projects/status/34csq3uurnw7c0rl?svg=true)](https://ci.appveyor.com/project/alexcrichton/libc)
[Documentation](#platforms-and-documentation)
## Usage
First, add the following to your `Cargo.toml`:
```toml
[dependencies]
libc = "0.2"
```
Next, add this to your crate root:
```rust
extern crate libc;
```
Currently libc by default links to the standard library, but if you would
instead like to use libc in a `#![no_std]` situation or crate you can request
this via:
```toml
[dependencies]
libc = { version = "0.2", default-features = false }
```
## What is libc?
The primary purpose of this crate is to provide all of the definitions necessary
to easily interoperate with C code (or "C-like" code) on each of the platforms
that Rust supports. This includes type definitions (e.g. `c_int`), constants
(e.g. `EINVAL`) as well as function headers (e.g. `malloc`).
This crate does not strive to have any form of compatibility across platforms,
but rather it is simply a straight binding to the system libraries on the
platform in question.
## Public API
This crate exports all underlying platform types, functions, and constants under
the crate root, so all items are accessible as `libc::foo`. The types and values
of all the exported APIs match the platform that libc is compiled for.
More detailed information about the design of this library can be found in its
[associated RFC][rfc].
[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1291-promote-libc.md
## Adding an API
Want to use an API which currently isn't bound in `libc`? It's quite easy to add
one!
The internal structure of this crate is designed to minimize the number of
`#[cfg]` attributes in order to easily be able to add new items which apply
to all platforms in the future. As a result, the crate is organized
hierarchically based on platform. Each module has a number of `#[cfg]`'d
children, but only one is ever actually compiled. Each module then reexports all
the contents of its children.
This means that for each platform that libc supports, the path from a
leaf module to the root will contain all bindings for the platform in question.
Consequently, this indicates where an API should be added! Adding an API at a
particular level in the hierarchy means that it is supported on all the child
platforms of that level. For example, when adding a Unix API it should be added
to `src/unix/mod.rs`, but when adding a Linux-only API it should be added to
`src/unix/notbsd/linux/mod.rs`.
If you're not 100% sure at what level of the hierarchy an API should be added
at, fear not! This crate has CI support which tests any binding against all
platforms supported, so you'll see failures if an API is added at the wrong
level or has different signatures across platforms.
With that in mind, the steps for adding a new API are:
1. Determine where in the module hierarchy your API should be added.
2. Add the API.
3. Send a PR to this repo.
4. Wait for CI to pass, fixing errors.
5. Wait for a merge!
### Test before you commit
We have two automated tests running on [Travis](https://travis-ci.org/rust-lang/libc):
1. [`libc-test`](https://github.com/alexcrichton/ctest)
- `cd libc-test && cargo run`
- Use the `skip_*()` functions in `build.rs` if you really need a workaround.
2. Style checker
- `rustc ci/style.rs && ./style src`

The goal of the libc crate is to have CI running everywhere to have the
strongest guarantees about the definitions that this library contains, and as a
result the CI is pretty complicated and also pretty large! Hopefully this can
serve as a guide through the sea of scripts in this directory and elsewhere in
this project.
# Files
First up, let's talk about the files in this directory:
* `run-travis.sh` - a shell script run by all Travis builders, this is
responsible for setting up the rest of the environment such as installing new
packages, downloading Rust target libraries, etc.
* `run.sh` - the actual script which runs tests for a particular architecture.
Called from the `run-travis.sh` script this will run all tests for the target
specified.
* `cargo-config` - Cargo configuration of linkers to use copied into place by
the `run-travis.sh` script before builds are run.
* `dox.sh` - script called from `run-travis.sh` on only the linux 64-bit nightly

# CI Systems
Currently this repository leverages a combination of Travis CI and AppVeyor for
running tests. The triples tested are:
* AppVeyor
* `{i686,x86_64}-pc-windows-{msvc,gnu}`
* Travis
* `{i686,x86_64,mips,aarch64}-unknown-linux-gnu`
* `x86_64-unknown-linux-musl`
* `arm-unknown-linux-gnueabihf`
* `arm-linux-androideabi`
* `{i686,x86_64}-apple-{darwin,ios}`
* `x86_64-rumprun-netbsd`
* `x86_64-unknown-freebsd`
* `x86_64-unknown-openbsd`
The Windows triples are all pretty standard, they just set up their environment
then run tests, no need for downloading any extra target libs (we just download
the right installer). The Intel Linux/OSX builds are similar in that we just
download the right target libs and run tests. Note that the Intel Linux/OSX
builds are run on stable/beta/nightly, but are the only ones that do so.
The remaining architectures look like:
* Android runs in a [docker image][android-docker] with an emulator, the NDK,
and the SDK already set up. The entire build happens within the docker image.
* The MIPS, ARM, and AArch64 builds all use the QEMU userspace emulator to run
the generated binary to actually verify the tests pass.
* The MUSL build just has to download a MUSL compiler and target libraries and
then otherwise runs tests normally.
* iOS builds need an extra linker flag currently, but beyond that they're built
as standard as everything else.
* The rumprun target builds an entire kernel from the test suite and then runs
it inside QEMU using the serial console to test whether it succeeded or
failed.
* The BSD builds, currently OpenBSD and FreeBSD, use QEMU to boot up a system
and compile/run tests. More information on that below.

## QEMU
Lots of the architectures tested here use QEMU in the tests, so it's worth going
over all the crazy capabilities QEMU has and the various flavors in which we use
it!
First up, QEMU has userspace emulation where it doesn't boot a full kernel, it
just runs a binary from another architecture (using the `qemu-<arch>` wrappers).
We provide it the runtime path for the dynamically loaded system libraries,
however. This strategy is used for all Linux architectures that aren't intel.
Note that one downside of this QEMU system is that threads are barely
implemented, so we're careful to not spawn many threads.
For the rumprun target the only output is a kernel image, so we just use that
plus the `rumpbake` command to create a full kernel image which is then run from
within QEMU.
Finally, the fun part, the BSDs. Quite a few hoops are jumped through to get CI
working for these platforms, but the gist of it looks like:
* Cross compiling from Linux to any of the BSDs seems to be quite non-standard.
We may be able to get it working but it might be difficult at that point to
ensure that the libc definitions align with what you'd get on the BSD itself.
As a result, we try to do compiles within the BSD distro.
* On Travis we can't run a VM-in-a-VM, so we resort to userspace emulation
(QEMU).
* Unfortunately on Travis we also can't use KVM, so the emulation is super slow.
With all that in mind, the way BSD is tested looks like:
1. Download a pre-prepared image for the OS being tested.
2. Generate the tests for the OS being tested. This involves running the `ctest`
library over libc to generate a Rust file and a C file which will then be
compiled into the final test.
3. Generate a disk image which will later be mounted by the OS being tested.
This image is mostly just the libc directory, but some modifications are made
to compile the generated files from step 2.
4. The kernel is booted in QEMU, and it is configured to detect the libc-test
image being available, run the test script, and then shut down afterwards.
5. Look for whether the tests passed in the serial console output of the kernel.
There's some pretty specific instructions for setting up each image (detailed
below), but the main gist of this is that we must avoid a vanilla `cargo run`
inside of the `libc-test` directory (which is what it's intended for) because
that would compile `syntex_syntax`, a large library, with userspace emulation.
This invariably times out on Travis, so we can't do that.
Once all those hoops are jumped through, however, we can be happy that we're
testing almost everything!
Below are some details of how to set up the initial OS images which are
downloaded. Each image must be enabled have input/output over the serial
console, log in automatically at the serial console, detect if a second drive in
QEMU is available, and if so mount it, run a script (it'll specifically be
`run-qemu.sh` in this folder which is copied into the generated image talked
about above), and then shut down.
### QEMU setup - FreeBSD
1. Download CD installer (most minimal is fine)
2. `qemu-img create -f qcow2 foo.qcow2 2G`
3. `qemu -cdrom foo.iso -drive if=virtio,file=foo.qcow2 -net nic,model=virtio -net user`
4. run installer
5. `echo 'console="comconsole"' >> /boot/loader.conf`
6. `echo 'autoboot_delay="0"' >> /boot/loader.conf`
7. look at /etc/ttys, see what getty argument is for ttyu0
8. edit /etc/gettytab, look for ttyu0 argument, prepend `:al=root` to line
beneath
(note that the current image has a `freebsd` user, but this isn't really
necessary)
Once that's done, arrange for this script to run at login:
```
#!/bin/sh
sudo kldload ext2fs
[ -e /dev/vtbd1 ] || exit 0
sudo mount -t ext2fs /dev/vtbd1 /mnt
sh /mnt/run.sh /mnt
sudo poweroff
```

### QEMU setup - OpenBSD
1. Download CD installer
2. `qemu-img create -f qcow2 foo.qcow2 2G`
3. `qemu -cdrom foo.iso -drive if=virtio,file=foo.qcow2 -net nic,model=virtio -net user`
4. run installer
5. `echo 'set tty com0' >> /etc/boot.conf`
6. `echo 'boot' >> /etc/boot.conf`
7. Modify /etc/ttys, change the `tty00` at the end from 'unknown off' to
'vt220 on secure'
8. Modify same line in /etc/ttys to have `"/root/foo.sh"` as the shell
9. Add this script to `/root/foo.sh`
```
#!/bin/sh
exec 1>/dev/tty00
exec 2>&1
if mount -t ext2fs /dev/sd1c /mnt; then
sh /mnt/run.sh /mnt
shutdown -ph now
fi
# limited shell...
exec /bin/sh < /dev/tty00
```
10. `chmod +x /root/foo.sh`

//! Simple script to verify the coding style of this library
//!
//! ## How to run
//!
//! The first argument to this script is the directory to run on, so running
//! this script should be as simple as:
//!
//! ```notrust
//! rustc ci/style.rs
//! ./style src
//! ```
//!
//! ## Guidelines
//!
//! The current style is:
//!
//! * No trailing whitespace
//! * No tabs
//! * 80-character lines
//! * `extern` instead of `extern "C"`
//! * Specific module layout:
//! 1. use directives
//! 2. typedefs
//! 3. structs
//! 4. constants
//! 5. f! { ... } functions
//! 6. extern functions
//! 7. modules + pub use
//!
//! Things not verified:
//!
//! * alignment
//! * 4-space tabs
//! * leading colons on paths
