2017-02-04libstd/net: Add `peek` APIs to UdpSocket and TcpStreamTyler Julian-16/+250
These methods enable socket reads without side-effects. That is, repeated calls to peek() return identical data. This is accomplished by providing the POSIX flag MSG_PEEK to the underlying socket read operations. This also moves the current implementation of recv_from out of the platform-independent sys_common and into respective sys/windows and sys/unix implementations. This allows for more platform-dependent implementations.

2017-01-29Add support for test suites emulated in QEMUAlex Crichton-1/+5
This commit adds support to the build system to execute test suites that cannot run natively but can instead run inside of a QEMU emulator. A proof-of-concept builder was added for the `arm-unknown-linux-gnueabihf` target to show off how this might work. In general the architecture is to have a server running inside of the emulator which a local client connects to. The protocol between the server/client supports compiling tests on the host and running them on the target inside the emulator. Closes #33114

2017-01-28Auto merge of #39234 - segevfiner:fix-backtraces-on-windows-gnu, r=petrochenkovbors-1/+180
Make backtraces work on Windows GNU targets again. This is done by adding a function that can return a filename to pass to backtrace_create_state. The filename is obtained in a safe way by first getting the filename, locking the file so it can't be moved, and then getting the filename again and making sure it's the same. See: https://github.com/rust-lang/rust/pull/37359#issuecomment-260123399 Issue: #33985 Note though that this isn't that pretty... I had to implement a `WideCharToMultiByte` wrapper function to convert to the ANSI code page. This will work better than only allowing ASCII provided that the ANSI code page is set to the user's local language, which is often the case. Also, please make sure that I didn't break the Unix build.

2017-01-25Auto merge of #38856 - zackw:process-envs, r=aturonbors-1/+36
Add std::process::Command::envs() `Command::envs()` adds a vector of key-value pairs to the child process environment all at once. Suggested in #38526. This is not fully baked and frankly I'm not sure it even _works_, but I need some help finishing it up, and this is the simplest way to show you what I've got. The problems I know exist and don't know how to solve, from most to least important, are: * [ ] I don't know if the type signature of the new function is correct. * [x] The new test might not be getting run. I didn't see it go by in the output of `x.py test src/libstd --stage 1`. * [x] The tidy check says ``process.rs:402: different `since` than before`` which I don't know what it means. r? @brson

2017-01-24Auto merge of #39048 - lambda:impl-tosocketaddrs-for-string, r=alexcrichtonbors-0/+20
impl ToSocketAddrs for String `ToSocketAddrs` is implemented for a number of different types, including `(IpAddr, u16)`, `&str`, and various others, for the convenience of being able to run things like `TcpListener::bind("10.11.12.13:1415")`. However, because this is a generic parameter with a trait bound, if you have a `String` you cannot pass it in, either directly as `TcpListener::bind(string)`, or the `TcpListener::bind(&string)` as you might expect due to deref coercion; you have to use `TcpListener::bind(&*string)`, which is noisy and hard to discover (though #39029 suggests better error messages to make it more discoverable). Rather than making people stumble over this, just implement `ToSocketAddrs` for `String`.

Document that `Metadata` can be obtained from `symlink_metadata` When retrieving the information about a syslink (specifically, when invoking `Metadata::is_symlink`) you generally want the `syslink_metadata`. It would be natural to point at both options to retrieve a `Metadata` value, as they are both appropriate (for different use cases).
2017-01-21Generalize envs() and args() to iterators.Zack Weinberg-6/+9
* Command::envs() now takes anything that is IntoIterator<Item=(K, V)> where both K and V are AsRef<OsStr>. * Since we're not 100% sure that's the right signature, envs() is now marked unstable. (You can use envs() with HashMap<str, str> but not Vec<(str, str)>, for instance.) * Update the test to match. * By analogy, args() now takes any IntoIterator<Item=S>, S: AsRef<OsStr>. This should be uncontroversial.
