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'. + +#![doc(html_logo_url = "http://www.rust-lang.org/logos/rust-logo-128x128-blk-v2.png", + html_favicon_url = "http://www.rust-lang.org/favicon.ico", + html_root_url = "http://doc.rust-lang.org/env_logger/")] +#![cfg_attr(test, deny(warnings))] + +extern crate log; + +use std::env; +use std::io::prelude::*; +use std::io; +use std::mem; + +use log::{Log, LogLevel, LogLevelFilter, LogRecord, SetLoggerError, LogMetadata}; + +#[cfg(feature = "regex")] +#[path = "regex.rs"] +mod filter; + +#[cfg(not(feature = "regex"))] +#[path = "string.rs"] +mod filter; + +/// The logger. +pub struct Logger { + directives: Vec, + filter: Option, + format: Box String + Sync + Send>, +} + +/// LogBuilder acts as builder for initializing the Logger. +/// It can be used to customize the log format, change the enviromental variable used +/// to provide the logging directives and also set the default log level filter. +/// +/// ## Example +/// +/// ``` +/// #[macro_use] +/// extern crate log; +/// extern crate env_logger; +/// +/// use std::env; +/// use log::{LogRecord, LogLevelFilter}; +/// use env_logger::LogBuilder; +/// +/// fn main() { +/// let format = |record: &LogRecord| { +/// format!("{} - {}", record.level(), record.args()) +/// }; +/// +/// let mut builder = LogBuilder::new(); +/// builder.format(format).filter(None, LogLevelFilter::Info); +/// +/// if env::var("RUST_LOG").is_ok() { +/// builder.parse(&env::var("RUST_LOG").unwrap()); +/// } +/// +/// builder.init().unwrap(); +/// +/// error!("error message"); +/// info!("info message"); +/// } +/// ``` +pub struct LogBuilder { + directives: Vec, + filter: Option, + format: Box String + Sync + Send>, +} + +impl LogBuilder { + /// Initializes the log builder with defaults + pub fn new() -> LogBuilder { + LogBuilder { + directives: Vec::new(), + filter: None, + format: Box::new(|record: &LogRecord| { + format!("{}:{}: {}", record.level(), + record.location().module_path(), record.args()) + }), + } + } + + /// Adds filters to the logger + /// + /// The given module (if any) will log at most the specified level provided. + /// If no module is provided then the filter will apply to all log messages. + pub fn filter(&mut self, + module: Option<&str>, + level: LogLevelFilter) -> &mut Self { + self.directives.push(LogDirective { + name: module.map(|s| s.to_string()), + level: level, + }); + self + } + + /// Sets the format function for formatting the log output. + /// + /// This function is called on each record logged to produce a string which + /// is actually printed out. + pub fn format(&mut self, format: F) -> &mut Self + where F: Fn(&LogRecord) -> String + Sync + Send + { + self.format = Box::new(format); + self + } + + /// Parses the directives string in the same form as the RUST_LOG + /// environment variable. + /// + /// See the module documentation for more details. + pub fn parse(&mut self, filters: &str) -> &mut Self { + let (directives, filter) = parse_logging_spec(filters); + + self.filter = filter; + + for directive in directives { + self.directives.push(directive); + } + self + } + + /// Initializes the global logger with an env logger. + /// + /// This should be called early in the execution of a Rust program, and the + /// global logger may only be initialized once.

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. `_` - for example, `CC_x86_64-unknown-linux-gnu` +2. `_` - for example, `CC_x86_64_unknown_linux_gnu` +3. `_` - for example, `HOST_CC` or `TARGET_CFLAGS` +4. `` - 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. diff --git a/src/vendor/gcc/appveyor.yml b/src/vendor/gcc/appveyor.yml new file mode 100644 index 00000000000..f6108c66514 --- /dev/null +++ b/src/vendor/gcc/appveyor.yml @@ -0,0 +1,35 @@ +environment: + matrix: + - TARGET: x86_64-pc-windows-msvc + ARCH: amd64 + VS: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat + - TARGET: x86_64-pc-windows-msvc + ARCH: amd64 + VS: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat + - TARGET: i686-pc-windows-msvc + ARCH: x86 + VS: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat + - TARGET: i686-pc-windows-msvc + ARCH: x86 + VS: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat + - TARGET: x86_64-pc-windows-gnu + MSYS_BITS: 64 + - TARGET: i686-pc-windows-gnu + MSYS_BITS: 32 +install: + - ps: Start-FileDownload "https://static.rust-lang.org/dist/rust-nightly-${env:TARGET}.exe" + - rust-nightly-%TARGET%.exe /VERYSILENT /NORESTART /DIR="C:\Program Files (x86)\Rust" + - if defined VS call "%VS%" %ARCH% + - set PATH=%PATH%;C:\Program Files (x86)\Rust\bin + - if defined MSYS_BITS set PATH=%PATH%;C:\msys64\mingw%MSYS_BITS%\bin + - rustc -V + - cargo -V + +build: false + +test_script: + - cargo test --target %TARGET% + - cargo test --features parallel --target %TARGET% + - cargo test --manifest-path gcc-test/Cargo.toml --target %TARGET% + - cargo test --manifest-path gcc-test/Cargo.toml --features parallel --target %TARGET% + - cargo test --manifest-path gcc-test/Cargo.toml --release --target %TARGET% diff --git a/src/vendor/gcc/src/bin/gcc-shim.rs b/src/vendor/gcc/src/bin/gcc-shim.rs new file mode 100644 index 00000000000..43fd811d361 --- /dev/null +++ b/src/vendor/gcc/src/bin/gcc-shim.rs @@ -0,0 +1,23 @@ +#![cfg_attr(test, allow(dead_code))] + +use std::env; +use std::fs::File; +use std::io::prelude::*; +use std::path::PathBuf; + +fn main() { + let out_dir = PathBuf::from(env::var_os("GCCTEST_OUT_DIR").unwrap()); + for i in 0.. { + let candidate = out_dir.join(format!("out{}", i)); + if candidate.exists() { + continue + } + let mut f = File::create(candidate).unwrap(); + for arg in env::args().skip(1) { + writeln!(f, "{}", arg).unwrap(); + } + + File::create(out_dir.join("libfoo.a")).unwrap(); + break + } +} diff --git a/src/vendor/gcc/src/lib.rs b/src/vendor/gcc/src/lib.rs new file mode 100644 index 00000000000..f319e9313ad --- /dev/null +++ b/src/vendor/gcc/src/lib.rs @@ -0,0 +1,959 @@ +//!

Construct a vector of options, either by using `reqopt`, `optopt`, and +//! `optflag` or by building them from components yourself, and pass them to +//! `getopts`, along with a vector of actual arguments (not including +//! `argv[0]`). You'll either get a failure code back, or a match. You'll have +//! to verify whether the amount of 'free' arguments in the match is what you +//! expect. Use `opt_*` accessors to get argument values out of the matches +//! object. +//! +//! Single-character options are expected to appear on the command line with a +//! single preceding dash; multiple-character options are expected to be +//! proceeded by two dashes. Options that expect an argument accept their +//! argument following either a space or an equals sign. Single-character +//! options don't require the space. +//! +//! # Usage +//! +//! This crate is [on crates.io](https://crates.io/crates/getopts) and can be +//! used by adding `getopts` to the dependencies in your project's `Cargo.toml`. +//! +//! ```toml +//!

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.

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. + +[android-docker]: https://github.com/rust-lang/rust-buildbot/blob/master/slaves/android/Dockerfile + +## 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-` 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.
