2015-10-20Add dropck unsafe escape hatch (UGEH) to vec::IntoIter.Felix S. Klock II-0/+1
Fix #29166
2015-10-06Add RFC 1238's `unsafe_destructor_blind_to_params` (UGEH) where needed.Felix S. Klock II-0/+1
I needed it in `RawVec`, `Vec`, and `TypedArena` for `rustc` to bootstrap; but of course that alone was not sufficient for `make check`. Later I added `unsafe_destructor_blind_to_params` to collections, in particular `LinkedList` and `RawTable` (the backing representation for `HashMap` and `HashSet`), to get the regression tests exercising cyclic structure from PR #27185 building. ---- Note that the feature is `dropck_parametricity` (which is not the same as the attribute's name). We will almost certainly vary our strategy here in the future, so it makes some sense to have a not-as-ugly name for the feature gate. (The attribute name was deliberately selected to be ugly looking.)

2015-09-20Do not drop_in_place elements of Vec<T> if T doesn't need droppingwhitequark-3/+5
With -O2, LLVM's inliner can remove this code, but this does not happen with -O1 and lower. As a result, dropping Vec<u8> was linear with length, resulting in abysmal performance for large buffers.
2015-09-11std: Stabilize/deprecate features for 1.4Alex Crichton-8/+2
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

2015-08-15collections: Add issues for unstable featuresAlex Crichton-8/+15
2015-08-12Remove all unstable deprecated functionalityAlex Crichton-326/+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.
2015-08-11Register new snapshotsAlex Crichton-3/+0
* Lots of core prelude imports removed * Makefile support for MSVC env vars and Rust crates removed * Makefile support for morestack removed
2015-08-09Replace many uses of `mem::transmute` with more specific functionsTobias Bucher-1/+1
The replacements are functions that usually use a single `mem::transmute` in their body and restrict input and output via more concrete types than `T` and `U`. Worth noting are the `transmute` functions for slices and the `from_utf8*` family for mutable slices. Additionally, `mem::transmute` was often used for casting raw pointers, when you can already cast raw pointers just fine with `as`.
2015-08-03syntax: Implement #![no_core]Alex Crichton-1/+3
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
2015-07-29Rollup merge of #27375 - niconii:vec-docs, r=GankroSteve Klabnik-1/+8
Noticed that syntax like `vec![0; 5]` is never mentioned in `Vec<T>`'s docs, nor used in any of its methods' docs, so I figured I should add a mention of it. Also noticed `vec!(1, 2)` being used in one spot while I was at it, so I fixed that as well for consistency's sake. r? @steveklabnik

2015-07-27std: Deprecate a number of unstable featuresAlex Crichton-0/+4
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

2015-07-17Auto merge of #26955 - Gankro:raw-vec, r=bluss,alexcrichtonbors-246/+44
Per the top level comment: A low-level utility for more ergonomically allocating, reallocating, and deallocating a a buffer of memory on the heap without having to worry about all the corner cases involved. This type is excellent for building your own data structures like Vec and VecDeque. In particular: * Produces heap::EMPTY on zero-sized types * Produces heap::EMPTY on zero-length allocations * Catches all overflows in capacity computations (promotes them to "capacity overflow" panics) * Guards against 32-bit systems allocating more than isize::MAX bytes * Guards against overflowing your length * Aborts on OOM * Avoids freeing heap::EMPTY * Contains a ptr::Unique and thus endows the user with all related benefits This type does not in anyway inspect the memory that it manages. When dropped it *will* free its memory, but it *won't* try to Drop its contents. It is up to the user of RawVec to handle the actual things *stored* inside of a RawVec. Note that a RawVec always forces its capacity to be usize::MAX for zero-sized types. This enables you to use capacity growing logic catch the overflows in your length that might occur with zero-sized types. However this means that you need to be careful when roundtripping this type with a `Box<[T]>`: `cap()` won't yield the len. However `with_capacity`, `shrink_to_fit`, and `from_box` will actually set RawVec's private capacity field. This allows zero-sized types to not be special-cased by consumers of this type. Edit: fixes #18726 and fixes #23842

2015-07-08Improve Vec::resize so that it can be used in Read::read_to_endUlrik Sverdrup-21/+28
We needed a more efficient way to zerofill the vector in read_to_end. This to reduce the memory intialization overhead to a minimum. Use the implementation of `std::vec::from_elem` (used for the vec![] macro) for Vec::resize as well. For simple element types like u8, this compiles to memset, so it makes Vec::resize much more efficient.

2015-06-26Auto merge of #25646 - huonw:align, r=alexcrichtonbors-7/+7
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.

2015-06-17Auto merge of #22681 - mzabaluev:extend-faster, r=huonwbors-39/+39
Instead of a fast branch with a sized iterator falling back to a potentially poorly optimized iterate-and-push loop, a single efficient loop can serve all cases. In my benchmark runs, I see some good gains, but also some regressions, possibly due to different inlining choices by the compiler. YMMV.
