Closes #22306.
2015-02-11rollup merge of #22015: alexcrichton/netv2Alex Crichton-0/+1
This commit is an implementation of [RFC 807][rfc] which adds a `std::net` module for basic neworking based on top of `std::io`. This module serves as a replacement for the `std::old_io::net` module and networking primitives in `old_io`. [rfc]: fillmein The major focus of this redesign is to cut back on the level of abstraction to the point that each of the networking types is just a bare socket. To this end functionality such as timeouts and cloning has been removed (although cloning can be done through `duplicate`, it may just yield an error). With this `net` module comes a new implementation of `SocketAddr` and `IpAddr`. This work is entirely based on #20785 and the only changes were to alter the in-memory representation to match the `libc`-expected variants and to move from public fields to accessors.

2015-02-11rustc: Fix a number of stability lint holesAlex Crichton-2/+3
There are a number of holes that the stability lint did not previously cover, including: * Types * Bounds on type parameters on functions and impls * Where clauses * Imports * Patterns (structs and enums) These holes have all been fixed by overriding the `visit_path` function on the AST visitor instead of a few specialized cases. This change also necessitated a few stability changes: * The `collections::fmt` module is now stable (it was already supposed to be). * The `thread_local::imp::Key` type is now stable (it was already supposed to be). * The `std::rt::{begin_unwind, begin_unwind_fmt}` functions are now stable. These are required via the `panic!` macro. * The `std::old_io::stdio::{println, println_args}` functions are now stable. These are required by the `print!` and `println!` macros. * The `ops::{FnOnce, FnMut, Fn}` traits are now `#[stable]`. This is required to make bounds with these traits stable. Note that manual implementations of these traits are still gated by default, this stability only allows bounds such as `F: FnOnce()`. Additionally, the compiler now has special logic to ignore its own generated `__test` module for the `--test` harness in terms of stability. Closes #8962 Closes #16360 Closes #20327 [breaking-change]

2015-02-03rollup merge of #21835: alexcrichton/iov2Alex Crichton-3/+3
This commit is an implementation of [RFC 576][rfc] which adds back the `std::io` module to the standard library. No functionality in `std::old_io` has been deprecated just yet, and the new `std::io` module is behind the same `io` feature gate. [rfc]: https://github.com/rust-lang/rfcs/pull/576 A good bit of functionality was copied over from `std::old_io`, but many tweaks were required for the new method signatures. Behavior such as precisely when buffered objects call to the underlying object may have been tweaked slightly in the transition. All implementations were audited to use composition wherever possible. For example the custom `pos` and `cap` cursors in `BufReader` were removed in favor of just using `Cursor<Vec<u8>>`. A few liberties were taken during this implementation which were not explicitly spelled out in the RFC: * The old `LineBufferedWriter` is now named `LineWriter` * The internal representation of `Error` now favors OS error codes (a 0-allocation path) and contains a `Box` for extra semantic data. * The io prelude currently reexports `Seek` as `NewSeek` to prevent conflicts with the real prelude reexport of `old_io::Seek` * The `chars` method was moved from `BufReadExt` to `ReadExt`. * The `chars` iterator returns a custom error with a variant that explains that the data was not valid UTF-8.

As part of [RFC 474](https://github.com/rust-lang/rfcs/pull/474), this commit renames `std::path` to `std::old_path`, leaving the existing path API in place to ease migration to the new one. Updating should be as simple as adjusting imports, and the prelude still maps to the old path APIs for now. [breaking-change]

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]

2015-01-26std: Rename io to old_ioAlex Crichton-3/+4
In preparation for the I/O rejuvination of the standard library, this commit renames the current `io` module to `old_io` in order to make room for the new I/O modules. It is expected that the I/O RFCs will land incrementally over time instead of all at once, and this provides a fresh clean path for new modules to enter into as well as guaranteeing that all old infrastructure will remain in place for some time. As each `old_io` module is replaced it will be deprecated in-place for new structures in `std::{io, fs, net}` (as appropriate). This commit does *not* leave a reexport of `old_io as io` as the deprecation lint does not currently warn on this form of use. This is quite a large breaking change for all imports in existing code, but all functionality is retained precisely as-is and path statements simply need to be renamed from `io` to `old_io`.

2015-01-20std: Rename Show/String to Debug/DisplayAlex Crichton-1/+1
This commit is an implementation of [RFC 565][rfc] which is a stabilization of the `std::fmt` module and the implementations of various formatting traits. Specifically, the following changes were performed: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0565-show-string-guidelines.md * The `Show` trait is now deprecated, it was renamed to `Debug` * The `String` trait is now deprecated, it was renamed to `Display` * Many `Debug` and `Display` implementations were audited in accordance with the RFC and audited implementations now have the `#[stable]` attribute * Integers and floats no longer print a suffix * Smart pointers no longer print details that they are a smart pointer * Paths with `Debug` are now quoted and escape characters * The `unwrap` methods on `Result` now require `Display` instead of `Debug` * The `Error` trait no longer has a `detail` method and now requires that `Display` must be implemented. With the loss of `String`, this has moved into libcore. * `impl<E: Error> FromError<E> for Box<Error>` now exists * `derive(Show)` has been renamed to `derive(Debug)`. This is not currently warned about due to warnings being emitted on stage1+ While backwards compatibility is attempted to be maintained with a blanket implementation of `Display` for the old `String` trait (and the same for `Show`/`Debug`) this is still a breaking change due to primitives no longer implementing `String` as well as modifications such as `unwrap` and the `Error` trait. Most code is fairly straightforward to update with a rename or tweaks of method calls. [breaking-change] Closes #21436

2015-01-17std: Move the bitflags! macro to a gated crateAlex Crichton-4/+3
In accordance with [collections reform part 2][rfc] this macro has been moved to an external [bitflags crate][crate] which is [available though crates.io][cratesio]. Inside the standard distribution the macro has been moved to a crate called `rustc_bitflags` for current users to continue using. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0509-collections-reform-part-2.md [crate]: https://github.com/rust-lang/bitflags [cratesio]: http://crates.io/crates/bitflags The major user of `bitflags!` in terms of a public-facing possibly-stable API today is the `FilePermissions` structure inside of `std::io`. This user, however, will likely no longer use `bitflags!` after I/O reform has landed. To prevent breaking APIs today, this structure remains as-is. Current users of the `bitflags!` macro should add this to their `Cargo.toml`: bitflags = "0.1" and this to their crate root: #[macro_use] extern crate bitflags; Due to the removal of a public macro, this is a: [breaking-change]

2015-01-07rollup merge of #20663: brson/feature-stagingAlex Crichton-0/+1
This partially implements the feature staging described in the [release channel RFC][rc]. It does not yet fully conform to the RFC as written, but does accomplish its goals sufficiently for the 1.0 alpha release. It has three primary user-visible effects: * On the nightly channel, use of unstable APIs generates a warning. * On the beta channel, use of unstable APIs generates a warning. * On the beta channel, use of feature gates generates a warning. Code that does not trigger these warnings is considered 'stable', modulo pre-1.0 bugs. Disabling the warnings for unstable APIs continues to be done in the existing (i.e. old) style, via `#[allow(...)]`, not that specified in the RFC. I deem this marginally acceptable since any code that must do this is not using the stable dialect of Rust. Use of feature gates is itself gated with the new 'unstable_features' lint, on nightly set to 'allow', and on beta 'warn'. The attribute scheme used here corresponds to an older version of the RFC, with the `#[staged_api]` crate attribute toggling the staging behavior of the stability attributes, but the user impact is only in-tree so I'm not concerned about having to make design changes later (and I may ultimately prefer the scheme here after all, with the `#[staged_api]` crate attribute). Since the Rust codebase itself makes use of unstable features the compiler and build system do a midly elaborate dance to allow it to bootstrap while disobeying these lints (which would otherwise be errors because Rust builds with `-D warnings`). This patch includes one significant hack that causes a regression. Because the `format_args!` macro emits calls to unstable APIs it would trigger the lint. I added a hack to the lint to make it not trigger, but this in turn causes arguments to `println!` not to be checked for feature gates. I don't presently understand macro expansion well enough to fix. This is bug #20661. Closes #16678 [rc]: https://github.com/rust-lang/rfcs/blob/master/text/0507-release-channels.md Next steps are to disable the existing out-of-tree behavior for stability attributes, and convert the remaining system to be feature-based per the RFC. During the first beta cycle we will set these lints to 'forbid'.
2015-01-08Added `box_syntax` feature gate; added to std and rustc crates for bootstrap.Felix S. Klock II-0/+1
To avoid using the feauture, change uses of `box <expr>` to `Box::new(<expr>)` alternative, as noted by the feature gate message. (Note that box patterns have no analogous trivial replacement, at least not in general; you need to revise the code to do a partial match, deref, and then the rest of the match.) [breaking-change]
