2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-2/+1
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

2015-10-25std: Stabilize library APIs for 1.5Alex Crichton-1/+1
This commit stabilizes and deprecates library APIs whose FCP has closed in the last cycle, specifically: Stabilized APIs: * `fs::canonicalize` * `Path::{metadata, symlink_metadata, canonicalize, read_link, read_dir, exists, is_file, is_dir}` - all moved to inherent methods from the `PathExt` trait. * `Formatter::fill` * `Formatter::width` * `Formatter::precision` * `Formatter::sign_plus` * `Formatter::sign_minus` * `Formatter::alternate` * `Formatter::sign_aware_zero_pad` * `string::ParseError` * `Utf8Error::valid_up_to` * `Iterator::{cmp, partial_cmp, eq, ne, lt, le, gt, ge}` * `<[T]>::split_{first,last}{,_mut}` * `Condvar::wait_timeout` - note that `wait_timeout_ms` is not yet deprecated but will be once 1.5 is released. * `str::{R,}MatchIndices` * `str::{r,}match_indices` * `char::from_u32_unchecked` * `VecDeque::insert` * `VecDeque::shrink_to_fit` * `VecDeque::as_slices` * `VecDeque::as_mut_slices` * `VecDeque::swap_remove_front` - (renamed from `swap_front_remove`) * `VecDeque::swap_remove_back` - (renamed from `swap_back_remove`) * `Vec::resize` * `str::slice_mut_unchecked` * `FileTypeExt` * `FileTypeExt::{is_block_device, is_char_device, is_fifo, is_socket}` * `BinaryHeap::from` - `from_vec` deprecated in favor of this * `BinaryHeap::into_vec` - plus a `Into` impl * `BinaryHeap::into_sorted_vec` Deprecated APIs * `slice::ref_slice` * `slice::mut_ref_slice` * `iter::{range_inclusive, RangeInclusive}` * `std::dynamic_lib` Closes #27706 Closes #27725 cc #27726 (align not stabilized yet) Closes #27734 Closes #27737 Closes #27742 Closes #27743 Closes #27772 Closes #27774 Closes #27777 Closes #27781 cc #27788 (a few remaining methods though) Closes #27790 Closes #27793 Closes #27796 Closes #27810 cc #28147 (not all parts stabilized)
2015-10-13Make the Metadata struct CloneBen S-0/+1
This commit adds #[derive(Clone)] to std::fs::Metadata, making that struct cloneable. Although the exact contents of that struct differ between OSes, they all have it contain only value types, meaning that the data can be re-used without repercussions. It also adds #[derive(Clone)] to every type used by that struct across all OSes, including the various Unix `stat` structs and Windows's `WIN32_FILE_ATTRIBUTE_DATA`.
2015-08-28Reduce the reliance on `PATH_MAX`Barosl Lee-15/+30
- Rewrite `std::sys::fs::readlink` not to rely on `PATH_MAX` It currently has the following problems: 1. It uses `_PC_NAME_MAX` to query the maximum length of a file path in the underlying system. However, the meaning of the constant is the maximum length of *a path component*, not a full path. The correct constant should be `_PC_PATH_MAX`. 2. `pathconf` *may* fail if the referred file does not exist. This can be problematic if the file which the symbolic link points to does not exist, but the link itself does exist. In this case, the current implementation resorts to the hard-coded value of `1024`, which is not ideal. 3. There may exist a platform where there is no limit on file path lengths in general. That's the reaon why GNU Hurd doesn't define `PATH_MAX` at all, in addition to having `pathconf` always returning `-1`. In these platforms, the content of the symbolic link can be silently truncated if the length exceeds the hard-coded limit mentioned above. 4. The value obtained by `pathconf` may be outdated at the point of actually calling `readlink`. This is inherently racy. This commit introduces a loop that gradually increases the length of the buffer passed to `readlink`, eliminating the need of `pathconf`. - Remove the arbitrary memory limit of `std::sys::fs::realpath` As per POSIX 2013, `realpath` will return a malloc'ed buffer if the second argument is a null pointer.[1] [1] http://pubs.opengroup.org/onlinepubs/9699919799/functions/realpath.html - Comment on functions that are still using `PATH_MAX` There are some functions that only work in terms of `PATH_MAX`, such as `F_GETPATH` in OS X. Comments on them for posterity.

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
2015-07-20std: Add IntoRaw{Fd,Handle,Socket} traitsAlex Crichton-0/+2
This commit is an implementation of [RFC 1174][rfc] which adds three new traits to the standard library: * `IntoRawFd` - implemented on Unix for all I/O types (files, sockets, etc) * `IntoRawHandle` - implemented on Windows for files, processes, etc * `IntoRawSocket` - implemented on Windows for networking types [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1174-into-raw-fd-socket-handle-traits.md Closes #27062

2015-07-10Auto merge of #26751 - retep998:copy-that-floppy, r=alexcrichtonbors-1/+17
Using the OS mechanism for copying files allows the OS to optimize the transfer using stuff such as [Offloaded Data Transfers (ODX)](https://msdn.microsoft.com/en-us/library/windows/desktop/hh848056%28v=vs.85%29.aspx). Also preserves a lot more information, including NTFS [File Streams](https://msdn.microsoft.com/en-us/library/windows/desktop/aa364404%28v=vs.85%29.aspx), which the manual implementation threw away. In addition, it is an atomic operation, unlike the manual implementation which has extra calls for copying over permissions. r? @alexcrichton

This commit stabilizes the following APIs, slating them all to be cherry-picked into the 1.1 release. * fs::FileType (and transitively the derived trait implementations) * fs::Metadata::file_type * fs::FileType::is_dir * fs::FileType::is_file * fs::FileType::is_symlink * fs::DirEntry::metadata * fs::DirEntry::file_type * fs::DirEntry::file_name * fs::set_permissions * fs::symlink_metadata * os::raw::{self, *} * os::{android, bitrig, linux, ...}::raw::{self, *} * os::{android, bitrig, linux, ...}::fs::MetadataExt * os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat * os::unix::fs::PermissionsExt * os::unix::fs::PermissionsExt::mode * os::unix::fs::PermissionsExt::set_mode * os::unix::fs::PermissionsExt::from_mode * os::unix::fs::OpenOptionsExt * os::unix::fs::OpenOptionsExt::mode * os::unix::fs::DirEntryExt * os::unix::fs::DirEntryExt::ino * os::windows::fs::MetadataExt * os::windows::fs::MetadataExt::file_attributes * os::windows::fs::MetadataExt::creation_time * os::windows::fs::MetadataExt::last_access_time * os::windows::fs::MetadataExt::last_write_time * os::windows::fs::MetadataExt::file_size The `os::unix::fs::Metadata` structure was also removed entirely, moving all of its associated methods into the `os::unix::fs::MetadataExt` trait instead. The methods are all marked as `#[stable]` still. As some minor cleanup, some deprecated and unstable fs apis were also removed: * File::path * Metadata::accessed * Metadata::modified Features that were explicitly left unstable include: * fs::WalkDir - the semantics of this were not considered in the recent fs expansion RFC. * fs::DirBuilder - it's still not 100% clear if the naming is right here and if the set of functionality exposed is appropriate. * fs::canonicalize - the implementation on Windows here is specifically in question as it always returns a verbatim path. Additionally the Unix implementation is susceptible to buffer overflows on long paths unfortunately. * fs::PathExt - as this is just a convenience trait, it is not stabilized at this time. * fs::set_file_times - this funciton is still waiting on a time abstraction.
2015-06-09std: Tweak process raising/lowering implementationsAlex Crichton-2/+0
* Slate these features to be stable in 1.2 instead of 1.1 (not being backported) * Have the `FromRawFd` implementations follow the contract of the `FromRawFd` trait by taking ownership of the primitive specified. * Refactor the implementations slightly to remove the `unreachable!` blocks as well as separating the stdio representation of `std::process` from `std::sys::process`.

2015-03-12Stabilize std::pathAaron Turon-0/+2
This commit stabilizes essentially all of the new `std::path` API. The API itself is changed in a couple of ways (which brings it in closer alignment with the RFC): * `.` components are now normalized away, unless they appear at the start of a path. This in turn effects the semantics of e.g. asking for the file name of `foo/` or `foo/.`, both of which yield `Some("foo")` now. This semantics is what the original RFC specified, and is also desirable given early experience rolling out the new API. * The `parent` function now succeeds if, and only if, the path has at least one non-root/prefix component. This change affects `pop` as well. * The `Prefix` component now involves a separate `PrefixComponent` struct, to better allow for keeping both parsed and unparsed prefix data. In addition, the `old_path` module is now deprecated. Closes #23264 [breaking-change]

2015-02-18std: Implement CString-related RFCsAlex Crichton-21/+21
This commit is an implementation of [RFC 592][r592] and [RFC 840][r840]. These two RFCs tweak the behavior of `CString` and add a new `CStr` unsized slice type to the module. [r592]: https://github.com/rust-lang/rfcs/blob/master/text/0592-c-str-deref.md [r840]: https://github.com/rust-lang/rfcs/blob/master/text/0840-no-panic-in-c-string.md The new `CStr` type is only constructable via two methods: 1. By `deref`'ing from a `CString` 2. Unsafely via `CStr::from_ptr` The purpose of `CStr` is to be an unsized type which is a thin pointer to a `libc::c_char` (currently it is a fat pointer slice due to implementation limitations). Strings from C can be safely represented with a `CStr` and an appropriate lifetime as well. Consumers of `&CString` should now consume `&CStr` instead to allow producers to pass in C-originating strings instead of just Rust-allocated strings. A new constructor was added to `CString`, `new`, which takes `T: IntoBytes` instead of separate `from_slice` and `from_vec` methods (both have been deprecated in favor of `new`). The `new` method returns a `Result` instead of panicking. The error variant contains the relevant information about where the error happened and bytes (if present). Conversions are provided to the `io::Error` and `old_io::IoError` types via the `FromError` trait which translate to `InvalidInput`. This is a breaking change due to the modification of existing `#[unstable]` APIs and new deprecation, and more detailed information can be found in the two RFCs. Notable breakage includes: * All construction of `CString` now needs to use `new` and handle the outgoing `Result`. * Usage of `CString` as a byte slice now explicitly needs a `.as_bytes()` call. * The `as_slice*` methods have been removed in favor of just having the `as_bytes*` methods.

2015-01-06core: split into fmt::Show and fmt::StringSean McArthur-1/+1
fmt::Show is for debugging, and can and should be implemented for all public types. This trait is used with `{:?}` syntax. There still exists #[derive(Show)]. fmt::String is for types that faithfully be represented as a String. Because of this, there is no way to derive fmt::String, all implementations must be purposeful. It is used by the default format syntax, `{}`. This will break most instances of `{}`, since that now requires the type to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the correct fix. Types that were being printed specifically for users should receive a fmt::String implementation to fix this. Part of #20013 [breaking-change]
2015-01-05std: Redesign c_str and c_vecAlex Crichton-23/+25
This commit is an implementation of [RFC 494][rfc] which removes the entire `std::c_vec` module and redesigns the `std::c_str` module as `std::ffi`. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0494-c_str-and-c_vec-stability.md The interface of the new `CString` is outlined in the linked RFC, the primary changes being: * The `ToCStr` trait is gone, meaning the `with_c_str` and `to_c_str` methods are now gone. These two methods are replaced with a `CString::from_slice` method. * The `CString` type is now just a wrapper around `Vec<u8>` with a static guarantee that there is a trailing nul byte with no internal nul bytes. This means that `CString` now implements `Deref<Target = [c_char]>`, which is where it gains most of its methods from. A few helper methods are added to acquire a slice of `u8` instead of `c_char`, as well as including a slice with the trailing nul byte if necessary. * All usage of non-owned `CString` values is now done via two functions inside of `std::ffi`, called `c_str_to_bytes` and `c_str_to_bytes_with_nul`. These functions are now the one method used to convert a `*const c_char` to a Rust slice of `u8`. Many more details, including newly deprecated methods, can be found linked in the RFC.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-7/+6
This commit is an implementation of [RFC 503][rfc] which is a stabilization story for the prelude. Most of the RFC was directly applied, removing reexports. Some reexports are kept around, however: * `range` remains until range syntax has landed to reduce churn. * `Path` and `GenericPath` remain until path reform lands. This is done to prevent many imports of `GenericPath` which will soon be removed. * All `io` traits remain until I/O reform lands so imports can be rewritten all at once to `std::io::prelude::*`. This is a breaking change because many prelude reexports have been removed, and the RFC can be consulted for the exact list of removed reexports, as well as to find the locations of where to import them.

2014-12-08auto merge of #19378 : japaric/rust/no-as-slice, r=alexcrichtonbors-1/+1
Now that we have an overloaded comparison (`==`) operator, and that `Vec`/`String` deref to `[T]`/`str` on method calls, many `as_slice()`/`as_mut_slice()`/`to_string()` calls have become redundant. This patch removes them. These were the most common patterns: - `assert_eq(test_output.as_slice(), "ground truth")` -> `assert_eq(test_output, "ground truth")` - `assert_eq(test_output, "ground truth".to_string())` -> `assert_eq(test_output, "ground truth")` - `vec.as_mut_slice().sort()` -> `vec.sort()` - `vec.as_slice().slice(from, to)` -> `vec.slice(from_to)` --- Note that e.g. `a_string.push_str(b_string.as_slice())` has been left untouched in this PR, since we first need to settle down whether we want to favor the `&*b_string` or the `b_string[]` notation. This is rebased on top of #19167 cc @alexcrichton @aturon

All of the enum components had a redundant 'Type' specifier: TypeSymlink, TypeDirectory, TypeFile. This change removes them, replacing them with a namespace: FileType::Symlink, FileType::Directory, and FileType::RegularFile. RegularFile is used instead of just File, as File by itself could be mistakenly thought of as referring to the struct. [breaking-change]
