After testing `--pretty normal`, it tries to run `--pretty expanded` and
typecheck output.
Here we don't check convergence since it really diverges: for every
iteration, some extra lines (e.g.`extern crate std`) are inserted.
Some tests are `ignore-pretty`-ed since they cause various issues
with `--pretty expanded`.
Some `Expr` needs parentheses when printed. For example, without
parentheses, `ExprUnary(UnNeg, ExprBinary(BiAdd, ..))` becomes
`-lhs + rhs` which is wrong.
Those cases don't appear in ordinary code (since parentheses are
explicitly added) but they can appear in manually crafted ast by
extensions.
Inject `extern crate {std, native}` before `use` statements.
Add `#![feature(glob)]` since `use std::prelude::*` is used.
(Unfortunately `rustc --pretty expanded` does not converge,
since `extern crate` and `use std::prelude::*` is injected at every
iteration.)
This is to clarify that match construct doesn't define a new variable, since I
observed a person reading the Rust tutorial who seemed to incorrectly think
that it did. Fixes https://github.com/mozilla/rust/issues/13571 .
The Normalizations iterator has been renamed to Decompositions.
It does not currently include all forms of Unicode normalization,
but only encompasses decompositions.
If implemented recomposition would likely be a separate iterator
which works on the result of this one.

The compiler was updated to recognize that implementations for ty_uniq(..) are
allowed if the Box lang item is located in the current crate. This enforces the
idea that libcore cannot allocated, and moves all related trait implementations
from libcore to libstd.
This is a breaking change in that the AnyOwnExt trait has moved from the any
module to the owned module. Any previous users of std::any::AnyOwnExt should now
use std::owned::AnyOwnExt instead. This was done because the trait is intended
for Box traits and only Box traits.

- Use Unicode-aware versions of `CreateProcess` (Fixes#13815) and `Get/FreeEnvironmentStrings`.
- Includes a helper function `os::win32::as_mut_utf16_p`, which does the same thing as `os::win32::as_utf16_p` except the pointer is mutable.
- Fixed `make_command_line` to handle Unicode correctly.
- Tests for the above.
Added a run-pass test to ensure that processes can be correctly spawned
using non-ASCII arguments, working directory, and environment variables.
It also tests Unicode support of os::env_as_bytes.
An additional assertion was added to the test for make_command_line to
verify it handles Unicode correctly.
Previously, make_command_line iterates over each u8 in the string and
then appends them as chars, so any non-ASCII string will get horribly
mangled by this function. This fix should allow Unicode arguments to
work correctly in native::io::process::spawn.
Changed libnative to use CreateProcessW instead of CreateProcessA. In
addition, the lpEnvironment parameter now uses Unicode.
Added a helper function os::win32::as_mut_utf16_p, which does basically
the same thing as os::win32::as_utf16_p except the pointer is mutable.
Changed StrBuf.shift_byte() that it no longer reallocates the buffer by just calling Vec.shift();
Added warning to shift_char()'s docs about it having to copy the whole buffer, as per the docs for
Vec.shift().
Been meaning to try my hand at something like this for a while, and noticed something similar mentioned as part of #13537. The suggestion on the original ticket is to use `TcpStream::open(&str)` to pass in a host + port string, but seems a little cleaner to pass in host and port separately -- so a signature like `TcpStream::open(&str, u16)`.
Also means we can use std::io::net::addrinfo directly instead of using e.g. liburl to parse the host+port pair from a string.
One outstanding issue in this PR that I'm not entirely sure how to address: in open_timeout, the timeout_ms will apply for every A record we find associated with a hostname -- probably not the intended behavior, but I didn't want to waste my time on elaborate alternatives until the general idea was a-OKed. :)
Anyway, perhaps there are other reasons for us to prefer the original proposed syntax, but thought I'd get some thoughts on this. Maybe there are some solid reasons to prefer using liburl to do this stuff.
Prior to this commit, TcpStream::connect and TcpListener::bind took a
single SocketAddr argument. This worked well enough, but the API felt a
little too "low level" for most simple use cases.
A great example is connecting to rust-lang.org on port 80. Rust users would
need to:
1. resolve the IP address of rust-lang.org using
io::net::addrinfo::get_host_addresses.
2. check for errors
3. if all went well, use the returned IP address and the port number
to construct a SocketAddr
4. pass this SocketAddr to TcpStream::connect.
I'm modifying the type signature of TcpStream::connect and
TcpListener::bind so that the API is a little easier to use.
TcpStream::connect now accepts two arguments: a string describing the
host/IP of the host we wish to connect to, and a u16 representing the
remote port number.
Similarly, TcpListener::bind has been modified to take two arguments:
a string describing the local interface address (e.g. "0.0.0.0" or
"127.0.0.1") and a u16 port number.
Here's how to port your Rust code to use the new TcpStream::connect API:
// old ::connect API
let addr = SocketAddr{ip: Ipv4Addr{127, 0, 0, 1}, port: 8080};
let stream = TcpStream::connect(addr).unwrap()
// new ::connect API (minimal change)
let addr = SocketAddr{ip: Ipv4Addr{127, 0, 0, 1}, port: 8080};
let stream = TcpStream::connect(addr.ip.to_str(), addr.port()).unwrap()
// new ::connect API (more compact)
let stream = TcpStream::connect("127.0.0.1", 8080).unwrap()
// new ::connect API (hostname)
let stream = TcpStream::connect("rust-lang.org", 80)
Similarly, for TcpListener::bind:
// old ::bind API
let addr = SocketAddr{ip: Ipv4Addr{0, 0, 0, 0}, port: 8080};
let mut acceptor = TcpListener::bind(addr).listen();
// new ::bind API (minimal change)
let addr = SocketAddr{ip: Ipv4Addr{0, 0, 0, 0}, port: 8080};
let mut acceptor = TcpListener::bind(addr.ip.to_str(), addr.port()).listen()
// new ::bind API (more compact)
let mut acceptor = TcpListener::bind("0.0.0.0", 8080).listen()

The `FileStat` struct contained a `path` field, which was filled by the
`stat` and `lstat` function. Since this field isn't in fact returned by
the operating system (it was copied from the paths passed to the
functions) it was removed, as in the `fstat` case we aren't working with
a `Path`, but directly with a fd.
If your code used the `path` field of `FileStat` you will now have to
manually store the path passed to `stat` along with the returned struct.
