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`.

utkarshkukreti:question-mark-in-libstd-documentation-examples, r=pnkfelix,steveklabnik,frewsxcvx libstd: replace all `try!` with `?` in documentation examples See #38644. For the record, I used the following Perl one-liner and then manually fixed a couple of things it got wrong: $ perl -p -i -e 's#(///.*)try!\((.*)\)#$1$2?#' src/libstd/**/*.rs

Use fs::symlink_metadata in doc for is_symlink fs::metadata() follows symlinks so is_symlink() will always return false. Use symlink_metadata instead in the example in the documentation. See issue #39088.

2017-01-21Auto merge of #39203 - ranma42:doc_metadata, r=BurntSushibors-3/+5
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.

2017-01-21Auto merge of #39086 - aidanhs:aphs-local-rebuild-no-jemalloc, r=alexcrichtonbors-4/+6
Make rustbuild force_alloc_system rather than relying on stage0 This 'fixes' jemalloc-less local rebuilds, where we tell cargo that we're actually stage1 (this only fixes the rustbuild path, since I wasn't enthusiastic to dive into the makefiles). There should be one effect from this PR: `--enable-local-rebuild --disable-jemalloc` will successfully build a stage0 std (rather than erroring). Ideally I think it'd be nice to specify an allocator preference in Cargo.toml/cargo command line (used when an allocator must be picked i.e. dylibs, not rlibs), but since that's not possible we can make do with a force_alloc_system feature. Sadly this locks you into a single allocator in the build libstd, making any eventual implementation of #38575 not quite right in this edge case, but clearly not many people exercise the combination of these two flags. This PR is also a substitute for #37975 I think. The crucial difference is that the feature name here is distinct from the jemalloc feature (reused in the previous PR) - we don't want someone to be forced into alloc_system just for disabling jemalloc! Fixes #39054 r? @alexcrichton

2017-01-20Rollup merge of #39120 - alexcrichton:emscripten-tests, r=brsonAlex Crichton-1/+2
travis: Get an emscripten builder online This commit adds a new entry to the Travis matrix which will execute emscripten test suites. Along the way it updates a few bits of the test suite to continue passing on emscripten, such as: * Ignoring i128/u128 tests as they're presumably just not working (didn't investigate as to why) * Disabling a few process tests (not working on emscripten) * Ignore some num tests in libstd (#39119) * Fix some warnings when compiling

PartialEq and PartialOrd between IpAddr and Ipv[46]Addr. PartialEq was rather useful, so, I figured that I'd implement it. I added PartialOrd for good measure.

std/net/udp: Improve set_nonblocking test While writing a separate change, I noticed the current test for `UdpSocket::set_nonblocking()` is fairly ineffective. This fixes the test so that it validates that a correct error is returned on calls to `recv()` when no data is available.

2017-01-12Auto merge of #38867 - alexcrichton:ignore-test-on-windows, r=brsonbors-0/+1
std: Ignore close_read_wakes_up on Windows It looks like in practice at least this test will not pass on Windows. Empirically it is prone to blocking forever, presumably because a call to `shutdown` doesn't actually wake up other threads on Windows. We don't document this as a guarantee for `shutdown`, nor do we internally rely on it. This test originated in a time long since passed when it was leveraged for canceling I/O, but nowadays there's nothing fancy happening in the standard library so it's not really a productive test anyway, hence just ignoring it on Windows. Closes #31657
