2016-02-03std: Stabilize custom hasher support in HashMapAlex Crichton-3/+2
This commit implements the stabilization of the custom hasher support intended for 1.7 but left out due to some last-minute questions that needed some decisions. A summary of the actions done in this PR are: Stable * `std::hash::BuildHasher` * `BuildHasher::Hasher` * `BuildHasher::build_hasher` * `std::hash::BuildHasherDefault` * `HashMap::with_hasher` * `HashMap::with_capacity_and_hasher` * `HashSet::with_hasher` * `HashSet::with_capacity_and_hasher` * `std::collections::hash_map::RandomState` * `RandomState::new` Deprecated * `std::collections::hash_state` * `std::collections::hash_state::HashState` - this trait was also moved into `std::hash` with a reexport here to ensure that we can have a blanket impl to prevent immediate breakage on nightly. Note that this is unstable in both location. * `HashMap::with_hash_state` - renamed * `HashMap::with_capacity_and_hash_state` - renamed * `HashSet::with_hash_state` - renamed * `HashSet::with_capacity_and_hash_state` - renamed Closes #27713

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-10/+4
This commit is the standard API stabilization commit for the 1.6 release cycle. The list of issues and APIs below have all been through their cycle-long FCP and the libs team decisions are listed below Stabilized APIs * `Read::read_exact` * `ErrorKind::UnexpectedEof` (renamed from `UnexpectedEOF`) * libcore -- this was a bit of a nuanced stabilization, the crate itself is now marked as `#[stable]` and the methods appearing via traits for primitives like `char` and `str` are now also marked as stable. Note that the extension traits themeselves are marked as unstable as they're imported via the prelude. The `try!` macro was also moved from the standard library into libcore to have the same interface. Otherwise the functions all have copied stability from the standard library now. * The `#![no_std]` attribute * `fs::DirBuilder` * `fs::DirBuilder::new` * `fs::DirBuilder::recursive` * `fs::DirBuilder::create` * `os::unix::fs::DirBuilderExt` * `os::unix::fs::DirBuilderExt::mode` * `vec::Drain` * `vec::Vec::drain` * `string::Drain` * `string::String::drain` * `vec_deque::Drain` * `vec_deque::VecDeque::drain` * `collections::hash_map::Drain` * `collections::hash_map::HashMap::drain` * `collections::hash_set::Drain` * `collections::hash_set::HashSet::drain` * `collections::binary_heap::Drain` * `collections::binary_heap::BinaryHeap::drain` * `Vec::extend_from_slice` (renamed from `push_all`) * `Mutex::get_mut` * `Mutex::into_inner` * `RwLock::get_mut` * `RwLock::into_inner` * `Iterator::min_by_key` (renamed from `min_by`) * `Iterator::max_by_key` (renamed from `max_by`) Deprecated APIs * `ErrorKind::UnexpectedEOF` (renamed to `UnexpectedEof`) * `OsString::from_bytes` * `OsStr::to_cstring` * `OsStr::to_bytes` * `fs::walk_dir` and `fs::WalkDir` * `path::Components::peek` * `slice::bytes::MutableByteVector` * `slice::bytes::copy_memory` * `Vec::push_all` (renamed to `extend_from_slice`) * `Duration::span` * `IpAddr` * `SocketAddr::ip` * `Read::tee` * `io::Tee` * `Write::broadcast` * `io::Broadcast` * `Iterator::min_by` (renamed to `min_by_key`) * `Iterator::max_by` (renamed to `max_by_key`) * `net::lookup_addr` New APIs (still unstable) * `<[T]>::sort_by_key` (added to mirror `min_by_key`) Closes #27585 Closes #27704 Closes #27707 Closes #27710 Closes #27711 Closes #27727 Closes #27740 Closes #27744 Closes #27799 Closes #27801 cc #27801 (doesn't close as `Chars` is still unstable) Closes #28968

2015-08-14rustc: Allow changing the default allocatorAlex Crichton-4/+4
This commit is an implementation of [RFC 1183][rfc] which allows swapping out the default allocator on nightly Rust. No new stable surface area should be added as a part of this commit. [rfc]: https://github.com/rust-lang/rfcs/pull/1183 Two new attributes have been added to the compiler: * `#![needs_allocator]` - this is used by liballoc (and likely only liballoc) to indicate that it requires an allocator crate to be in scope. * `#![allocator]` - this is a indicator that the crate is an allocator which can satisfy the `needs_allocator` attribute above. The ABI of the allocator crate is defined to be a set of symbols that implement the standard Rust allocation/deallocation functions. The symbols are not currently checked for exhaustiveness or typechecked. There are also a number of restrictions on these crates: * An allocator crate cannot transitively depend on a crate that is flagged as needing an allocator (e.g. allocator crates can't depend on liballoc). * There can only be one explicitly linked allocator in a final image. * If no allocator is explicitly requested one will be injected on behalf of the compiler. Binaries and Rust dylibs will use jemalloc by default where available and staticlibs/other dylibs will use the system allocator by default. Two allocators are provided by the distribution by default, `alloc_system` and `alloc_jemalloc` which operate as advertised. Closes #27389
2015-08-14Auto merge of #27641 - nikomatsakis:soundness-rfc-1214, r=nrcbors-0/+5
This PR implements the majority of RFC 1214. In particular, it implements: - the new outlives relation - comprehensive WF checking For the most part, new code receives warnings, not errors, though 3 regressions were found via a crater run. There are some deviations from RFC 1214. Most notably: - we still consider implied bounds from fn ret; this intersects other soundness issues that I intend to address in detail in a follow-up RFC. Fixing this without breaking a lot of code probably requires rewriting compare-method somewhat (which is probably a good thing). - object types do not check trait bounds for fear of encountering `Self`; this was left as an unresolved question in RFC 1214, but ultimately feels inconsistent. Both of those two issues are highlighted in the tracking issue, https://github.com/rust-lang/rust/issues/27579. #27579 also includes a testing matrix with new tests that I wrote -- these probably duplicate some existing tests, I tried to check but wasn't quite sure what to look for. I tried to be thorough in testing the WF relation, at least, but would welcome suggestions for missing tests. r? @nrc (or perhaps someone else?)

2015-08-12Remove all unstable deprecated functionalityAlex Crichton-27/+15
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.
2015-08-10Stabilize the Duration APISteven Fackler-2/+2
This commit stabilizes the `std::time` module and the `Duration` type. `Duration::span` remains unstable, and the `Display` implementation for `Duration` has been removed as it is still being reworked and all trait implementations for stable types are de facto stable. This is a [breaking-change] to those using `Duration`'s `Display` implementation.

2015-07-27std: Deprecate a number of unstable featuresAlex Crichton-1/+2
Many of these have long since reached their stage of being obsolete, so this commit starts the removal process for all of them. The unstable features that were deprecated are: * cmp_partial * fs_time * hash_default * int_slice * iter_min_max * iter_reset_fuse * iter_to_vec * map_in_place * move_from * owned_ascii_ext * page_size * read_and_zero * scan_state * slice_chars * slice_position_elem * subslice_offset

2015-07-12Auto merge of #26895 - jroesch:modernize-typeck-names, r=nikomatsakisbors-2/+2
This PR modernizes some names in the type checker. The only remaining snake_case name in ty.rs is `ctxt` which should be resolved by @eddyb's pending refactor. We can bike shed over the names, it would just be nice to bring the type checker inline with modern Rust. r? @eddyb cc @nikomatsakis
