2015-04-21rollup merge of #24222: lambda/rename-soft-link-to-symlinkAlex Crichton-1/+6
Implement [RFC #1048][rfc]. On Windows, when you create a symbolic link you must specify whether it points to a directory or a file, even if it is created dangling, while on Unix, the same symbolic link could point to a directory, a file, or nothing at all. Furthermore, on Windows special privilege is necessary to use a symbolic link, while on Unix, you can generally create a symbolic link in any directory you have write privileges to. This means that it is unlikely to be able to use symbolic links purely portably; anyone who uses them will need to think about the cross platform implications. This means that using platform-specific APIs will make it easier to see where code will need to differ between the platforms, rather than trying to provide some kind of compatibility wrapper. Furthermore, `soft_link` has no precedence in any other API, so to avoid confusion, move back to the more standard `symlink` terminology. Create a `std::os::unix::symlink` for the Unix version that is destination type agnostic, as well as `std::os::windows::{symlink_file, symlink_dir}` for Windows. Because this is a stable API, leave a compatibility wrapper in `std::fs::soft_link`, which calls `symlink` on Unix and `symlink_file` on Windows, preserving the existing behavior of `soft_link`.

2015-04-21Implement Debug for FileChris Wong-0/+10
This patch adds a `Debug` impl for `std::fs::File`. On all platforms (Unix and Windows) it shows the file descriptor. On Linux, it displays the path and access mode as well. Ideally we should show the path/mode for all platforms, not just Linux, but this will do for now. cc #24570
2015-04-08std: Fix fs::read_link behavior on WindowsAlex Crichton-14/+33
The current implementation of using GetFinalPathNameByHandle actually reads all intermediate links instead of just looking at the current link. This commit alters the behavior of the function to use a different API which correctly reads only one level of the soft link. [breaking-change]
2015-03-26std: Stabilize parts of std::os::platform::ioAlex Crichton-4/+11
This commit stabilizes the platform-specific `io` modules, specifically around the traits having to do with the raw representation of each object on each platform. Specifically, the following material was stabilized: * `AsRaw{Fd,Socket,Handle}` * `RawFd` (renamed from `Fd`) * `RawHandle` (renamed from `Handle`) * `RawSocket` (renamed from `Socket`) * `AsRaw{Fd,Socket,Handle}` implementations * `std::os::{unix, windows}::io` The following material was added as `#[unstable]`: * `FromRaw{Fd,Socket,Handle}` * Implementations for various primitives There are a number of future improvements that are possible to make to this module, but this should cover a good bit of functionality desired from these modules for now. Some specific future additions may include: * `IntoRawXXX` traits to consume the raw representation and cancel the auto-destructor. * `Fd`, `Socket`, and `Handle` abstractions that behave like Rust objects and have nice methods for various syscalls. At this time though, these are considered backwards-compatible extensions and will not be stabilized at this time. This commit is a breaking change due to the addition of `Raw` in from of the type aliases in each of the platform-specific modules. [breaking-change]

2015-02-20std: Ensure fs::{DirEntry, ReadDir} are Send/SyncAlex Crichton-12/+27
The windows/unix modules were currently inconsistent about the traits being implemented for `DirEntry` and there isn't much particular reason why the traits *couldn't* be implemented for `ReadDir` and `DirEntry`, so this commit ensures that they are implemented. Closes #22577
2015-02-13Add std::processAaron Turon-18/+2
Per [RFC 579](https://github.com/rust-lang/rfcs/pull/579), this commit adds a new `std::process` module. This module is largely based on the existing `std::old_io::process` module, but refactors the API to use `OsStr` and other new standards set out by IO reform. The existing module is not yet deprecated, to allow for the new API to get a bit of testing before a mass migration to it.
2015-02-09std: Add a new `fs` moduleAlex Crichton-0/+428
This commit is an implementation of [RFC 739][rfc] which adds a new `std::fs` module to the standard library. This module provides much of the same functionality as `std::old_io::fs` but it has many tweaked APIs as well as uses the new `std::path` module. [rfc]: https://github.com/rust-lang/rfcs/pull/739
