2015-02-18Update the libraries to reflect Send loosing the 'static bound.Huon Wilson-38/+38
In most places this preserves the current API by adding an explicit `'static` bound. Notably absent are some impls like `unsafe impl<T: Send> Send for Foo<T>` and the `std::thread` module. It is likely that it will be possible to remove these after auditing the code to ensure restricted lifetimes are safe. More progress on #22251.

2015-02-11rustc: Fix a number of stability lint holesAlex Crichton-13/+13
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]

2015-01-30std: Stabilize the std::fmt moduleAlex Crichton-3/+3
This commit performs a final stabilization pass over the std::fmt module, marking all necessary APIs as stable. One of the more interesting aspects of this module is that it exposes a good deal of its runtime representation to the outside world in order for `format_args!` to be able to construct the format strings. Instead of hacking the compiler to assume that these items are stable, this commit instead lays out a story for the stabilization and evolution of these APIs. There are three primary details used by the `format_args!` macro: 1. `Arguments` - an opaque package of a "compiled format string". This structure is passed around and the `write` function is the source of truth for transforming a compiled format string into a string at runtime. This must be able to be constructed in stable code. 2. `Argument` - an opaque structure representing an argument to a format string. This is *almost* a trait object as it's just a pointer/function pair, but due to the function originating from one of many traits, it's not actually a trait object. Like `Arguments`, this must be constructed from stable code. 3. `fmt::rt` - this module contains the runtime type definitions primarily for the `rt::Argument` structure. Whenever an argument is formatted with nonstandard flags, a corresponding `rt::Argument` is generated describing how the argument is being formatted. This can be used to construct an `Arguments`. The primary interface to `std::fmt` is the `Arguments` structure, and as such this type name is stabilize as-is today. It is expected for libraries to pass around an `Arguments` structure to represent a pending formatted computation. The remaining portions are largely "cruft" which would rather not be stabilized, but due to the stability checks they must be. As a result, almost all pieces have been renamed to represent that they are "version 1" of the formatting representation. The theory is that at a later date if we change the representation of these types we can add new definitions called "version 2" and corresponding constructors for `Arguments`. One of the other remaining large questions about the fmt module were how the pending I/O reform would affect the signatures of methods in the module. Due to [RFC 526][rfc], however, the writers of fmt are now incompatible with the writers of io, so this question has largely been solved. As a result the interfaces are largely stabilized as-is today. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0526-fmt-text-writer.md Specifically, the following changes were made: * The contents of `fmt::rt` were all moved under `fmt::rt::v1` * `fmt::rt` is stable * `fmt::rt::v1` is stable * `Error` is stable * `Writer` is stable * `Writer::write_str` is stable * `Writer::write_fmt` is stable * `Formatter` is stable * `Argument` has been renamed to `ArgumentV1` and is stable * `ArgumentV1::new` is stable * `ArgumentV1::from_uint` is stable * `Arguments::new_v1` is stable (renamed from `new`) * `Arguments::new_v1_formatted` is stable (renamed from `with_placeholders`) * All formatting traits are now stable, as well as the `fmt` method. * `fmt::write` is stable * `fmt::format` is stable * `Formatter::pad_integral` is stable * `Formatter::pad` is stable * `Formatter::write_str` is stable * `Formatter::write_fmt` is stable * Some assorted top level items which were only used by `format_args!` were removed in favor of static functions on `ArgumentV1` as well. * The formatting-flag-accessing methods remain unstable Within the contents of the `fmt::rt::v1` module, the following actions were taken: * Reexports of all enum variants were removed * All prefixes on enum variants were removed * A few miscellaneous enum variants were renamed * Otherwise all structs, fields, and variants were marked stable. In addition to these actions in the `std::fmt` module, many implementations of `Show` and `String` were stabilized as well. In some other modules: * `ToString` is now stable * `ToString::to_string` is now stable * `Vec` no longer implements `fmt::Writer` (this has moved to `String`) This is a breaking change due to all of the changes to the `fmt::rt` module, but this likely will not have much impact on existing programs.

2015-01-23std: Relax Result::unwrap() to DebugAlex Crichton-2/+19
This commit relaxes the bound on `Result::unwrap` and `Result::unwrap_err` from the `Display` trait to the `Debug` trait for generating an error message about the unwrapping operation. This commit is a breaking change and any breakage should be mitigated by ensuring that `Debug` is implemented on the relevant type. [breaking-change]

2015-01-20std: Rename Show/String to Debug/DisplayAlex Crichton-8/+12
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

2015-01-08Improvements to feature stagingBrian Anderson-3/+3
This gets rid of the 'experimental' level, removes the non-staged_api case (i.e. stability levels for out-of-tree crates), and lets the staged_api attributes use 'unstable' and 'deprecated' lints. This makes the transition period to the full feature staging design a bit nicer.

2015-01-06rollup merge of #20615: aturon/stab-2-threadAlex Crichton-35/+35
This commit takes a first pass at stabilizing `std::thread`: * It removes the `detach` method in favor of two constructors -- `spawn` for detached threads, `scoped` for "scoped" (i.e., must-join) threads. This addresses some of the surprise/frustrating debug sessions with the previous API, in which `spawn` produced a guard that on destruction joined the thread (unless `detach` was called). The reason to have the division in part is that `Send` will soon not imply `'static`, which means that `scoped` thread creation can take a closure over *shared stack data* of the parent thread. On the other hand, this means that the parent must not pop the relevant stack frames while the child thread is running. The `JoinGuard` is used to prevent this from happening by joining on drop (if you have not already explicitly `join`ed.) The APIs around `scoped` are future-proofed for the `Send` changes by taking an additional lifetime parameter. With the current definition of `Send`, this is forced to be `'static`, but when `Send` changes these APIs will gain their full flexibility immediately. Threads that are `spawn`ed, on the other hand, are detached from the start and do not yield an RAII guard. The hope is that, by making `scoped` an explicit opt-in with a very suggestive name, it will be drastically less likely to be caught by a surprising deadlock due to an implicit join at the end of a scope. * The module itself is marked stable. * Existing methods other than `spawn` and `scoped` are marked stable. The migration path is: ```rust Thread::spawn(f).detached() ``` becomes ```rust Thread::spawn(f) ``` while ```rust let res = Thread::spawn(f); res.join() ``` becomes ```rust let res = Thread::scoped(f); res.join() ``` [breaking-change]
