2015-11-09std: Migrate to the new libcAlex Crichton-27/+16
* Delete `sys::unix::{c, sync}` as these are now all folded into libc itself * Update all references to use `libc` as a result. * Update all references to the new flat namespace. * Moves all windows bindings into sys::c
2015-09-11std: Internalize almost all of `std::rt`Alex Crichton-2/+2
This commit does some refactoring to make almost all of the `std::rt` private. Specifically, the following items are no longer part of its API: * DEFAULT_ERROR_CODE * backtrace * unwind * args * at_exit * cleanup * heap (this is just alloc::heap) * min_stack * util The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is an entry point for the `panic!` macro via the `begin_unwind` and `begin_unwind_fmt` reexports.

2015-09-01std: Run TLS destructors in a statically linked binaryAlex Crichton-9/+29
Running TLS destructors for a MSVC Windows binary requires the linker doesn't elide the `_tls_used` or `__tls_used` symbols (depending on the architecture). This is currently achieved via a `#[link_args]` hack but this only works for dynamically linked binaries because the link arguments aren't propagated to statically linked binaries. This commit alters the strategy to instead emit a volatile load from those symbols so LLVM can't elide it, forcing the reference to the symbol to stay alive as long as the callback function stays alive (which we've made sure of with the `#[linkage]` attribute). Closes #28111
2015-07-20std: Fix compiling the standard library on i686-MSVCAlex Crichton-1/+4
This commit fixes building the standard library with the `i686-pc-windows-msvc` target by correcting an included symbol name to the linker.
2015-07-01msvc: Fix TLS destructorsAlex Crichton-2/+6
Just like the original article our Windows TLS support is based on predicted, this symbol must be linked in on MSVC to pull in the necessary support for TLS variables. This commit fixes a number of unit tests which require that TLS destructors are run.

2015-05-09Squeeze the last bits of `task`s in documentation in favor of `thread`Barosl Lee-1/+1
An automated script was run against the `.rs` and `.md` files, subsituting every occurrence of `task` with `thread`. In the `.rs` files, only the texts in the comment blocks were affected.

Now that support has been removed, all lingering use cases are renamed.

2015-02-23Use boxed functions instead of transmuteStepan Koltsov-2/+2
... to convert between Box and raw pointers. E. g. use ``` let b: Box<Foo> = Box::from_raw(p); ``` instead of ``` let b: Box<Foo> = mem::transmute(p); ``` Patch also changes closure release code in `src/libstd/sys/unix/thread.rs` when `pthread_create` failed. Raw pointer was transmuted to box of `FnOnce()` instead of `Thunk`. This code was probably never executed, because `pthread_create` rarely fails in practice.

2015-02-01std: Add a new `env` moduleAlex Crichton-0/+1
This is an implementation of [RFC 578][rfc] which adds a new `std::env` module to replace most of the functionality in the current `std::os` module. More details can be found in the RFC itself, but as a summary the following methods have all been deprecated: [rfc]: https://github.com/rust-lang/rfcs/pull/578 * `os::args_as_bytes` => `env::args` * `os::args` => `env::args` * `os::consts` => `env::consts` * `os::dll_filename` => no replacement, use `env::consts` directly * `os::page_size` => `env::page_size` * `os::make_absolute` => use `env::current_dir` + `join` instead * `os::getcwd` => `env::current_dir` * `os::change_dir` => `env::set_current_dir` * `os::homedir` => `env::home_dir` * `os::tmpdir` => `env::temp_dir` * `os::join_paths` => `env::join_paths` * `os::split_paths` => `env::split_paths` * `os::self_exe_name` => `env::current_exe` * `os::self_exe_path` => use `env::current_exe` + `pop` * `os::set_exit_status` => `env::set_exit_status` * `os::get_exit_status` => `env::get_exit_status` * `os::env` => `env::vars` * `os::env_as_bytes` => `env::vars` * `os::getenv` => `env::var` or `env::var_string` * `os::getenv_as_bytes` => `env::var` * `os::setenv` => `env::set_var` * `os::unsetenv` => `env::remove_var` Many function signatures have also been tweaked for various purposes, but the main changes were: * `Vec`-returning APIs now all return iterators instead * All APIs are now centered around `OsString` instead of `Vec<u8>` or `String`. There is currently on convenience API, `env::var_string`, which can be used to get the value of an environment variable as a unicode `String`. All old APIs are `#[deprecated]` in-place and will remain for some time to allow for migrations. The semantics of the APIs have been tweaked slightly with regard to dealing with invalid unicode (panic instead of replacement). The new `std::env` module is all contained within the `env` feature, so crates must add the following to access the new APIs: #![feature(env)] [breaking-change]

2015-01-02std: Stabilize the prelude moduleAlex Crichton-1/+1
This commit is an implementation of [RFC 503][rfc] which is a stabilization story for the prelude. Most of the RFC was directly applied, removing reexports. Some reexports are kept around, however: * `range` remains until range syntax has landed to reduce churn. * `Path` and `GenericPath` remain until path reform lands. This is done to prevent many imports of `GenericPath` which will soon be removed. * All `io` traits remain until I/O reform lands so imports can be rewritten all at once to `std::io::prelude::*`. This is a breaking change because many prelude reexports have been removed, and the RFC can be consulted for the exact list of removed reexports, as well as to find the locations of where to import them. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0503-prelude-stabilization.md [breaking-change] Closes #20068
2014-12-18std: Lower abstractions for thread_local/at_exitAlex Crichton-20/+42
The current implementations use `std::sync` primitives, but these primitives currently end up relying on `thread_info` and a local `Thread` being available (mainly for checking the panicking flag). To get around this, this commit lowers the abstractions used by the windows thread_local implementation as well as the at_exit_imp module. Both of these modules now use a `sys::Mutex` and a `static mut` and manage the allocation/locking manually.
2014-12-18Revise std::thread API to join by defaultAaron Turon-5/+4
This commit is part of a series that introduces a `std::thread` API to replace `std::task`. In the new API, `spawn` returns a `JoinGuard`, which by default will join the spawned thread when dropped. It can also be used to join explicitly at any time, returning the thread's result. Alternatively, the spawned thread can be explicitly detached (so no join takes place). As part of this change, Rust processes now terminate when the main thread exits, even if other detached threads are still running, moving Rust closer to standard threading models. This new behavior may break code that was relying on the previously implicit join-all. In addition to the above, the new thread API also offers some built-in support for building blocking abstractions in user space; see the module doc for details. Closes #18000 [breaking-change]
2014-12-18libs: merge librustrt into libstdAaron Turon-3/+3
This commit merges the `rustrt` crate into `std`, undoing part of the facade. This merger continues the paring down of the runtime system. Code relying on the public API of `rustrt` will break; some of this API is now available through `std::rt`, but is likely to change and/or be removed very soon. [breaking-change]

2014-11-23std: Add a new top-level thread_local moduleAlex Crichton-0/+238
This commit removes the `std::local_data` module in favor of a new `std::thread_local` module providing thread local storage. The module provides two variants of TLS: one which owns its contents and one which is based on scoped references. Each implementation has pros and cons listed in the documentation. Both flavors have accessors through a function called `with` which yield a reference to a closure provided. Both flavors also panic if a reference cannot be yielded and provide a function to test whether an access would panic or not. This is an implementation of [RFC 461][rfc] and full details can be found in that RFC. This is a breaking change due to the removal of the `std::local_data` module. All users can migrate to the new thread local system like so: thread_local!(static FOO: Rc<RefCell<Option<T>>> = Rc::new(RefCell::new(None))) The old `local_data` module inherently contained the `Rc<RefCell<Option<T>>>` as an implementation detail which must now be explicitly stated by users. [rfc]: https://github.com/rust-lang/rfcs/pull/461 [breaking-change]
