2016-05-26std: Stabilize APIs for the 1.10 releaseAlex Crichton-21/+13
This commit applies the FCP decisions made by the libs team for the 1.10 cycle, including both new stabilizations and deprecations. Specifically, the list of APIs is: Stabilized: * `os::windows::fs::OpenOptionsExt::access_mode` * `os::windows::fs::OpenOptionsExt::share_mode` * `os::windows::fs::OpenOptionsExt::custom_flags` * `os::windows::fs::OpenOptionsExt::attributes` * `os::windows::fs::OpenOptionsExt::security_qos_flags` * `os::unix::fs::OpenOptionsExt::custom_flags` * `sync::Weak::new` * `Default for sync::Weak` * `panic::set_hook` * `panic::take_hook` * `panic::PanicInfo` * `panic::PanicInfo::payload` * `panic::PanicInfo::location` * `panic::Location` * `panic::Location::file` * `panic::Location::line` * `ffi::CStr::from_bytes_with_nul` * `ffi::CStr::from_bytes_with_nul_unchecked` * `ffi::FromBytesWithNulError` * `fs::Metadata::modified` * `fs::Metadata::accessed` * `fs::Metadata::created` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange_weak` * `collections::{btree,hash}_map::{Occupied,Vacant,}Entry::key` * `os::unix::net::{UnixStream, UnixListener, UnixDatagram, SocketAddr}` * `SocketAddr::is_unnamed` * `SocketAddr::as_pathname` * `UnixStream::connect` * `UnixStream::pair` * `UnixStream::try_clone` * `UnixStream::local_addr` * `UnixStream::peer_addr` * `UnixStream::set_read_timeout` * `UnixStream::set_write_timeout` * `UnixStream::read_timeout` * `UnixStream::write_Timeout` * `UnixStream::set_nonblocking` * `UnixStream::take_error` * `UnixStream::shutdown` * Read/Write/RawFd impls for `UnixStream` * `UnixListener::bind` * `UnixListener::accept` * `UnixListener::try_clone` * `UnixListener::local_addr` * `UnixListener::set_nonblocking` * `UnixListener::take_error` * `UnixListener::incoming` * RawFd impls for `UnixListener` * `UnixDatagram::bind` * `UnixDatagram::unbound` * `UnixDatagram::pair` * `UnixDatagram::connect` * `UnixDatagram::try_clone` * `UnixDatagram::local_addr` * `UnixDatagram::peer_addr` * `UnixDatagram::recv_from` * `UnixDatagram::recv` * `UnixDatagram::send_to` * `UnixDatagram::send` * `UnixDatagram::set_read_timeout` * `UnixDatagram::set_write_timeout` * `UnixDatagram::read_timeout` * `UnixDatagram::write_timeout` * `UnixDatagram::set_nonblocking` * `UnixDatagram::take_error` * `UnixDatagram::shutdown` * RawFd impls for `UnixDatagram` * `{BTree,Hash}Map::values_mut` * `<[_]>::binary_search_by_key` Deprecated: * `StaticCondvar` - this, and all other static synchronization primitives below, are usable today through the lazy-static crate on stable Rust today. Additionally, we'd like the non-static versions to be directly usable in a static context one day, so they're unlikely to be the final forms of the APIs in any case. * `CONDVAR_INIT` * `StaticMutex` * `MUTEX_INIT` * `StaticRwLock` * `RWLOCK_INIT` * `iter::Peekable::is_empty` Closes #27717 Closes #27720 cc #27784 (but encode methods still exist) Closes #30014 Closes #30425 Closes #30449 Closes #31190 Closes #31399 Closes #31767 Closes #32111 Closes #32281 Closes #32312 Closes #32551 Closes #33018

2016-05-19Auto merge of #33103 - ranma42:escape-unicode-last, r=alexcrichtonbors-0/+12
Implement `last` for `EscapeUnicode` The implementation is quite trivial as the last character is always `'{'`. As a side-effect it also improves the implementation of `last` for `EscapeUnicode`. Part of #24214, split from #31049. Maybe this (and the other changes that I will split from #31049) should wait for a test like `ed_iterator_specializations` to be added. Would it be sufficient to do the same for each possible escape length?

2016-05-16Auto merge of #33429 - ranma42:fix-x87-parsing, r=alexcrichtonbors-10/+81
Fix fast path of float parsing on x87 The fast path of the float parser relies on the rounding to happen exactly and directly to the correct number of bits. On x87, instead, double rounding would occour as the FPU stack defaults to 80 bits of precision. This can be fixed by setting the precision of the FPU stack before performing the int to float conversion. This can be achieved by changing the value of the x87 control word. This is a somewhat common operation that is in fact performed whenever a float needs to be truncated to an integer, but it is undesirable to add its overhead for code that does not rely on x87 for computations (i.e. on non-x86 architectures, or x86 architectures which perform FPU computations on using SSE). Fixes `num::dec2flt::fast_path_correct` (on x87).

2016-05-14Auto merge of #33579 - Amanieu:atomic_bool2, r=alexcrichtonbors-58/+36
Make AtomicBool the same size as bool Reopening #32365 This allows `AtomicBool` to be transmuted to a `bool`, which makes it more consistent with the other atomic types. Note that this now guarantees that the atomic type will always contain a valid `bool` value, which wasn't the case before (due to `fetch_nand`). r? @alexcrichton

2016-05-12Auto merge of #33282 - alexcrichton:rustbuild-crate-tests, r=brsonbors-0/+7
rustbuild: Add support for crate tests + doctests This commit adds support to rustbuild to run crate unit tests (those defined by `#[test]`) as well as documentation tests. All tests are powered by `cargo test` under the hood. Each step requires the `libtest` library is built for that corresponding stage. Ideally the `test` crate would be a dev-dependency, but for now it's just easier to ensure that we sequence everything in the right order. Currently no filtering is implemented, so there's not actually a method of testing *only* libstd or *only* libcore, but rather entire swaths of crates are tested all at once. A few points of note here are: * The `coretest` and `collectionstest` crates are just listed as `[[test]]` entires for `cargo test` to naturally pick up. This mean that `cargo test -p core` actually runs all the tests for libcore. * Libraries that aren't tested all mention `test = false` in their `Cargo.toml` * Crates aren't currently allowed to have dev-dependencies due to rust-lang/cargo#860, but we can likely alleviate this restriction once workspaces are implemented. cc #31590

Short-cut `T: Sized` trait selection for ADTs Basically avoids all nested obligations when checking whether an ADT is sized - this speeds up typeck by ~15% The refactoring fixed #32963, but I also want to make `Copy` not object-safe (will commit that soon). Fixes #33201 r? @nikomatsakis

2016-05-03require the non-last elements of a tuple to be SizedAriel Ben-Yehuda-1/+1
This requirement appears to be missing from RFC1214, but is clearly necessary for translation. The last field of a tuple/enum remains in a state of limbo, compiling but causing an ICE when it is used - we should eventually fix that somehow. this is a [breaking-change] - a soundness fix - and requires a crater run.

docs: Changed docs for `size_of` to describe size as a stride offset Current documentation for `std::mem::size_of` is ambiguous, and the documentation for `std::intrinsics::size_of` incorrectly defines size. This fix re-defines size as the offset in bytes between successive instances of a type, as described in LLVM's [getTypeAllocSize](http://llvm.org/docs/doxygen/html/classllvm_1_1DataLayout.html#a1d6fcc02e91ba24510aba42660c90e29).

Current description of `std::mem::size_of` is ambiguous, and the `std::intrinsics::size_of` description incorrectly defines size as the number of bytes necessary to exactly overwrite a value, not including the padding between elements necessary in a vector or structure.
