2015-09-11std: Stabilize/deprecate features for 1.4Alex Crichton-26/+18
The FCP is coming to a close and 1.4 is coming out soon, so this brings in the libs team decision for all library features this cycle. Stabilized APIs: * `<Box<str>>::into_string` * `Arc::downgrade` * `Arc::get_mut` * `Arc::make_mut` * `Arc::try_unwrap` * `Box::from_raw` * `Box::into_raw` * `CStr::to_str` * `CStr::to_string_lossy` * `CString::from_raw` * `CString::into_raw` * `IntoRawFd::into_raw_fd` * `IntoRawFd` * `IntoRawHandle::into_raw_handle` * `IntoRawHandle` * `IntoRawSocket::into_raw_socket` * `IntoRawSocket` * `Rc::downgrade` * `Rc::get_mut` * `Rc::make_mut` * `Rc::try_unwrap` * `Result::expect` * `String::into_boxed_slice` * `TcpSocket::read_timeout` * `TcpSocket::set_read_timeout` * `TcpSocket::set_write_timeout` * `TcpSocket::write_timeout` * `UdpSocket::read_timeout` * `UdpSocket::set_read_timeout` * `UdpSocket::set_write_timeout` * `UdpSocket::write_timeout` * `Vec::append` * `Vec::split_off` * `VecDeque::append` * `VecDeque::retain` * `VecDeque::split_off` * `rc::Weak::upgrade` * `rc::Weak` * `slice::Iter::as_slice` * `slice::IterMut::into_slice` * `str::CharIndices::as_str` * `str::Chars::as_str` * `str::split_at_mut` * `str::split_at` * `sync::Weak::upgrade` * `sync::Weak` * `thread::park_timeout` * `thread::sleep` Deprecated APIs * `BTreeMap::with_b` * `BTreeSet::with_b` * `Option::as_mut_slice` * `Option::as_slice` * `Result::as_mut_slice` * `Result::as_slice` * `f32::from_str_radix` * `f64::from_str_radix` Closes #27277 Closes #27718 Closes #27736 Closes #27764 Closes #27765 Closes #27766 Closes #27767 Closes #27768 Closes #27769 Closes #27771 Closes #27773 Closes #27775 Closes #27776 Closes #27785 Closes #27792 Closes #27795 Closes #27797

2015-08-19Rework Rc for FCP of #27718Alexis Beingessner-82/+117
* Add `Rc::would_unwrap(&Self) -> bool` to introspect whether try_unwrap would succeed, because it's destructive (unlike get_mut). * Move `rc.downgrade()` to `Rc::downgrade(&Self)` per conventions. * Deprecate `Rc::weak_count` and `Rc::strong_count` for questionable utility. * Deprecate `Rc::is_unique` for questionable semantics (there are two kinds of uniqueness with Weak pointers in play). * Rename `rc.make_unique()` to `Rc::make_mut(&mut Self)` per conventions, to avoid uniqueness terminology, and to clarify the relation to `Rc::get_mut`.

2015-08-12Remove all unstable deprecated functionalityAlex Crichton-106/+28
This commit removes all unstable and deprecated functions in the standard library. A release was recently cut (1.3) which makes this a good time for some spring cleaning of the deprecated functions.

2015-08-03syntax: Implement #![no_core]Alex Crichton-1/+2
This commit is an implementation of [RFC 1184][rfc] which tweaks the behavior of the `#![no_std]` attribute and adds a new `#![no_core]` attribute. The `#![no_std]` attribute now injects `extern crate core` at the top of the crate as well as the libcore prelude into all modules (in the same manner as the standard library's prelude). The `#![no_core]` attribute disables both std and core injection. [rfc]: https://github.com/rust-lang/rfcs/pull/1184

2015-06-24Make `align_of` behave like `min_align_of`.Huon Wilson-4/+4
This removes a footgun, since it is a reasonable assumption to make that pointers to `T` will be aligned to `align_of::<T>()`. This also matches the behaviour of C/C++. `min_align_of` is now deprecated. Closes #21611.

2015-06-17std: Move free-functions to associated functionsAlex Crichton-28/+105
This commit moves the free functions in the `rc`, `arc`, and `boxed` modules to associated functions on their respective types, following the recent trend towards this pattern. The previous free functions are all left in-place with `#[deprecated]` pointers towards the new locations. This commit also deprecates `arc::get_mut` and `Arc::make_unique` with no replacement as they are racy in the face of weak pointers.

2015-05-20Auto merge of #25588 - bluss:doc-string-from, r=alexcrichtonbors-2/+2
Use stable code in doc examples (libcollections) Main task is to change from String::from_str to String::from in examples for String (the latter constructor is stable). While I'm at it, also remove redundant feature flags, fix some other instances of unstable code in examples (in examples for stable methods), and remove some use of usize in examples too.

2015-05-19collections: Avoid unstable code in examples for StringUlrik Sverdrup-2/+2
Prefer String::from over from_str; String::from_str is unstable while String::from is stable. Promote the latter by using it in examples. Simply migrating unstable function to the closest alternative.

2015-03-26Switch drop-flag to `u8` to allow special tags to instrument state.Felix S. Klock II-3/+3
Refactored code so that the drop-flag values for initialized (`DTOR_NEEDED`) versus dropped (`DTOR_DONE`) are given explicit names. Add `mem::dropped()` (which with `DTOR_DONE == 0` is semantically the same as `mem::zeroed`, but the point is that it abstracts away from the particular choice of value for `DTOR_DONE`). Filling-drop needs to use something other than `ptr::read_and_zero`, so I added such a function: `ptr::read_and_drop`. But, libraries should not use it if they can otherwise avoid it. Fixes to tests to accommodate filling-drop.

2015-03-03Add `: Box<_>` or `::Box<_>` type annotations to various places.Felix S. Klock II-1/+2
This is the kind of change that one is expected to need to make to accommodate overloaded-`box`. ---- Note that this is not *all* of the changes necessary to accommodate Issue 22181. It is merely the subset of those cases where there was already a let-binding in place that made it easy to add the necesasry type ascription. (For unnamed intermediate `Box` values, one must go down a different route; `Box::new` is the option that maximizes portability, but has potential inefficiency depending on whether the call is inlined.) ---- There is one place worth note, `run-pass/coerce-match.rs`, where I used an ugly form of `Box<_>` type ascription where I would have preferred to use `Box::new` to accommodate overloaded-`box`. I deliberately did not use `Box::new` here, because that is already done in coerce-match-calls.rs. ---- Precursor for overloaded-`box` and placement-`in`; see Issue 22181.

2015-02-23Use boxed functions instead of transmuteStepan Koltsov-2/+3
... 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.

2015-02-18Stabilize std::borrowAaron Turon-7/+0
This commit stabilizes `std::borrow`, making the following modifications to catch up the API with language changes: * It renames `BorrowFrom` to `Borrow`, as was originally intended (but blocked for technical reasons), and reorders the parameters accordingly. * It moves the type parameter of `ToOwned` to an associated type. This is somewhat less flexible, in that each borrowed type must have a unique owned type, but leads to a significant simplification for `Cow`. Flexibility can be regained by using newtyped slices, which is advisable for other reasons anyway. * It removes the owned type parameter from `Cow`, making the type much less verbose. * Deprecates the `is_owned` and `is_borrowed` predicates in favor of direct matching. The above API changes are relatively minor; the basic functionality remains the same, and essentially the whole module is now marked `#[stable]`. [breaking-change]
2015-02-18std: Stabilize the `hash` moduleAlex Crichton-2/+10
This commit is an implementation of [RFC 823][rfc] which is another pass over the `std::hash` module for stabilization. The contents of the module were not entirely marked stable, but some portions which remained quite similar to the previous incarnation are now marked `#[stable]`. Specifically: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0823-hash-simplification.md * `std::hash` is now stable (the name) * `Hash` is now stable * `Hash::hash` is now stable * `Hasher` is now stable * `SipHasher` is now stable * `SipHasher::new` and `new_with_keys` are now stable * `Hasher for SipHasher` is now stable * Many `Hash` implementations are now stable All other portions of the `hash` module remain `#[unstable]` as they are less commonly used and were recently redesigned. This commit is a breaking change due to the modifications to the `std::hash` API and more details can be found on the [RFC][rfc]. Closes #22467 [breaking-change]
