doc: Mention that writeln! and println! always use LF Fixes #34697 I'm not really satisfied with the wording, but I didn't have a better idea. Suggestions welcome.

2016-07-13Auto merge of #34776 - cuviper:solaris-readdir, r=alexcrichtonbors-22/+40
std: fix `readdir` errors for solaris A `NULL` from `readdir` could be the end of stream or an error. The only way to know is to check `errno`, so it must be set to a known value first, like a 0 that POSIX will never use. This currently only matters for solaris targets, as the other unix platforms are using `readdir_r` with a direct error return indication. However, this is getting deprecated (#34668) so they should all eventually switch to `readdir`. This PR adds `set_errno`, uses it to clear the value before calling `readdir`, then checks it again after to see the reason for a `NULL`. A few other small fixes are included just to get solaris compiling at all. I couldn't get cross-compilation completely going, so I don't have a good way to test this beyond a smoke-test cargo build of std. I'd appreciate input from someone more familiar with solaris -- cc @nbaksalyar?
2016-07-12Auto merge of #34756 - habnabit:mutex-refunwindsafe, r=alexcrichtonbors-0/+5
Mutex and RwLock need RefUnwindSafe too Incomplete, because I don't know what the appropriate stability annotation is here, but this is an attempt to bring the documentation for `std::panic` in line with reality. Right now, it says: >Types like `&Mutex<T>`, however, are unwind safe because they implement poisoning by default. But only `Mutex<T>`, not `&Mutex<T>`, is unwind-safe.
2016-07-12Auto merge of #34739 - therealbstern:ipv4unspec, r=alexcrichtonbors-0/+4
Mark Ipv4Addr is_unspecified as stable and provide reference. Per [#27709 (comment)](https://github.com/rust-lang/rust/issues/27709#issuecomment-231280999), no RFC is needed here. IPv4 "unspecified" has been defined in [Stevens], and has been part of the IPv4 stack for quite some time. This property should become stable, since this use of 0.0.0.0 is not going anywhere. [Stevens][_UNIX Network Programming Volume 1, Second Edition_. Stevens, W. Richard. Prentice-Hall, 1998. p. 891] Please let me know if I got the rustdoc wrong or something. I tried to be as terse as possible while still conveying the appropriate information. This also has a slight impact on PR #34694, but that one came first, so this shouldn't block it, IMO.

2016-07-12Auto merge of #34705 - alexcrichton:clean-deprecated, r=brsonbors-732/+234
std: Clean out deprecated APIs This primarily removes a lot of `sync::Static*` APIs and rejiggers the associated implementations. While doing this it was discovered that the `is_poisoned` method can actually result in a data race for the Mutex/RwLock primitives, so the inner `Cell<bool>` was changed to an `AtomicBool` to prevent the associated data race. Otherwise the usage/gurantees should be the same they were before.

2016-07-11std: clear errno before readdir, then check it (solaris)Josh Stone-17/+32
A `NULL` from `readdir` could be the end of stream or an error. The only way to know is to check `errno`, so it must be set to a known value first, like a 0 that POSIX will never use. This patch adds `set_errno`, uses it to clear the value before calling `readdir`, then checks it again after to see the reason for a `NULL`.
2016-07-11std: Fix IPV6 imports for solarisJosh Stone-4/+8
Like BSDs, Solaris maps `IPV6_ADD_MEMBERSHIP` and `IPV6_DROP_MEMBERSHIP` from `IPV6_JOIN_GROUP` and `IPV6_LEAVE_GROUP` respectively.
2016-07-11std: Fix `Thread::set_name()` for newlib and solarisJosh Stone-1/+0
The `use ffi::CStr` in `unix/thread.rs` was previously guarded, but now all platforms need it for `Thread::set_name()`. Newlib and Solaris do nothing here, as they have no way to set a thread name, but they still define the same method signature.

2016-07-08Auto merge of #34700 - inejge:ai-hints, r=alexcrichtonbors-0/+19
Use hints with getaddrinfo() in std::net::lookup_host() As noted in #24250, `std::net::lookup_host()` repeats each IPv[46] address in the result set. The number of repetitions is OS-dependent; e.g., Linux and FreeBSD give three copies, OpenBSD gives two. Filtering the duplicates can be done by the user if `lookup_host()` is used explicitly, but not with functions like `TcpStream::connect()`. What happens with the latter is that any unsuccessful connection attempt will be repeated as many times as there are duplicates of the address. The program: ```rust use std::net::TcpStream; fn main() { let _stream = TcpStream::connect("localhost:4444").unwrap(); } ``` results in the following capture: [capture-before.txt](https://github.com/rust-lang/rust/files/352004/capture-before.txt) assuming that "localhost" resolves both to ::1 and 127.0.0.1, and that the listening program opens just an IPv4 socket (e.g., `nc -l 127.0.0.1 4444`.) The reason for this behavior is explained in [this comment](https://github.com/rust-lang/rust/issues/24250#issuecomment-92240152): `getaddrinfo()` is not constrained. Various OSS projects (I checked out Postfix, OpenLDAP, Apache HTTPD and BIND) which use `getaddrinfo()` generally constrain the result set by using a non-NULL `hints` parameter and setting at least `ai_socktype` to `SOCK_STREAM`. `SOCK_DGRAM` would also work. Other parameters are unnecessary for pure name resolution. The patch in this PR initializes a `hints` struct and passes it to `getaddrinfo()`, which eliminates the duplicates. The same test program as above with this change produces: [capture-after.txt](https://github.com/rust-lang/rust/files/352042/capture-after.txt) All `libstd` tests pass with this patch.

Currently, the `mpsc::Receiver` offers methods for receiving values in both blocking (`recv`) and non-blocking (`try_recv`) flavours. However only blocking iteration over values is supported. This commit adds a non-blocking iterator to complement the `try_recv` method, just as the blocking iterator complements the `recv` method.
