2016-08-14Rollup merge of #35574 - badboy:emscripten-test-fixes, r=brsonEduard-Mihai Burtescu-8/+9
Emscripten test fixes This picks up parts of #31623 to disable certain tests that emscripten can't run, as threads/processes are not supported. I re-applied @tomaka's changes manually, I can rebase those commits with his credentials if he wants. It also disables jemalloc for emscripten (at least in Rustbuild, I have to check if there is another setting for the same thing in the old makefile approach). This should not impact anything for normal builds.

2016-07-28Auto merge of #34485 - tbu-:pr_unicode_debug_str, r=alexcrichtonbors-3/+3
Escape fewer Unicode codepoints in `Debug` impl of `str` Use the same procedure as Python to determine whether a character is printable, described in [PEP 3138]. In particular, this means that the following character classes are escaped: - Cc (Other, Control) - Cf (Other, Format) - Cs (Other, Surrogate), even though they can't appear in Rust strings - Co (Other, Private Use) - Cn (Other, Not Assigned) - Zl (Separator, Line) - Zp (Separator, Paragraph) - Zs (Separator, Space), except for the ASCII space `' '` `0x20` This allows for user-friendly inspection of strings that are not English (e.g. compare `"\u{e9}\u{e8}\u{ea}"` to `"éèê"`). Fixes #34318. CC #34422. [PEP 3138]: https://www.python.org/dev/peps/pep-3138/

2016-07-27Auto merge of #33312 - Byron:double-ended-iterator-for-args, r=alexcrichtonbors-10/+21
DoubleEndedIterator for Args This PR implements the DoubleEndedIterator trait for the `std::env::Args[Os]` structure, as well as the internal implementations. It is primarily motivated by me, as I happened to implement a simple `reversor` program many times now, which so far had to use code like this: ```Rust for arg in std::env::args().skip(1).collect::<Vec<_>>().iter().rev() {} ``` ... even though I would have loved to do this instead: ```Rust for arg in std::env::args().skip(1).rev() {} ``` The latter is more natural, and I did not find a reason for not implementing it. After all, on every system, the number of arguments passed to the program are known at runtime. To my mind, it follows KISS, and does not try to be smart at all. Also, there are no unit-tests, primarily as I did not find any existing tests for the `Args` struct either. The windows implementation is basically a copy-pasted variant of the `next()` method implementation, and I could imagine sharing most of the code instead. Actually I would be happy if the reviewer would ask for it.

2016-07-26DoubleEndedIterator for ArgsSebastian Thiel-10/+21
The number of arguments given to a process is always known, which makes implementing DoubleEndedIterator possible. That way, the Iterator::rev() method becomes usable, among others. Signed-off-by: Sebastian Thiel <byronimo@gmail.com> Tidy for DoubleEndedIterator I chose to not create a new feature for it, even though technically, this makes me lie about the original availability of the implementation. Verify with @alexchrichton Setup feature flag for new std::env::Args iterators Add test for Args reverse iterator It's somewhat depending on the input of the test program, but made in such a way that should be somewhat flexible to changes to the way it is called. Deduplicate windows ArgsOS code for DEI DEI = DoubleEndedIterator Move env::args().rev() test to run-pass It must be controlling it's arguments for full isolation. Remove superfluous feature name Assert all arguments returned by env::args().rev() Let's be very sure it works as we expect, why take chances. Fix rval of os_string_from_ptr A trait cannot be returned, but only the corresponding object. Deref pointers to actually operate on the argument Put unsafe to correct location

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 #34705 - alexcrichton:clean-deprecated, r=brsonbors-52/+64
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.

2016-06-29Ignore unknown address types when looking up hostsTobias Bucher-5/+9
Previously, any function using a `ToSocketAddrs` input would fail if passed a hostname that resolves to an address type different from the ones recognized by Rust. This also changes the `LookupHost` iterator to only include the known address types, as a result, it doesn't have to return `Result`s any more, which are likely misinterpreted as failed name lookups.
