2016-07-26DoubleEndedIterator for ArgsSebastian Thiel-0/+4
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

2016-07-11std: clear errno before readdir, then check it (solaris)Josh Stone-16/+25
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`.
2016-05-24std: Stabilize APIs for the 1.10 releaseAlex Crichton-19/+33
This commit applies the FCP decisions made by the libs team for the 1.10 cycle, including both new stabilizations and deprecations. Specifically, the list of APIs is: Stabilized: * `os::windows::fs::OpenOptionsExt::access_mode` * `os::windows::fs::OpenOptionsExt::share_mode` * `os::windows::fs::OpenOptionsExt::custom_flags` * `os::windows::fs::OpenOptionsExt::attributes` * `os::windows::fs::OpenOptionsExt::security_qos_flags` * `os::unix::fs::OpenOptionsExt::custom_flags` * `sync::Weak::new` * `Default for sync::Weak` * `panic::set_hook` * `panic::take_hook` * `panic::PanicInfo` * `panic::PanicInfo::payload` * `panic::PanicInfo::location` * `panic::Location` * `panic::Location::file` * `panic::Location::line` * `ffi::CStr::from_bytes_with_nul` * `ffi::CStr::from_bytes_with_nul_unchecked` * `ffi::FromBytesWithNulError` * `fs::Metadata::modified` * `fs::Metadata::accessed` * `fs::Metadata::created` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange_weak` * `collections::{btree,hash}_map::{Occupied,Vacant,}Entry::key` * `os::unix::net::{UnixStream, UnixListener, UnixDatagram, SocketAddr}` * `SocketAddr::is_unnamed` * `SocketAddr::as_pathname` * `UnixStream::connect` * `UnixStream::pair` * `UnixStream::try_clone` * `UnixStream::local_addr` * `UnixStream::peer_addr` * `UnixStream::set_read_timeout` * `UnixStream::set_write_timeout` * `UnixStream::read_timeout` * `UnixStream::write_Timeout` * `UnixStream::set_nonblocking` * `UnixStream::take_error` * `UnixStream::shutdown` * Read/Write/RawFd impls for `UnixStream` * `UnixListener::bind` * `UnixListener::accept` * `UnixListener::try_clone` * `UnixListener::local_addr` * `UnixListener::set_nonblocking` * `UnixListener::take_error` * `UnixListener::incoming` * RawFd impls for `UnixListener` * `UnixDatagram::bind` * `UnixDatagram::unbound` * `UnixDatagram::pair` * `UnixDatagram::connect` * `UnixDatagram::try_clone` * `UnixDatagram::local_addr` * `UnixDatagram::peer_addr` * `UnixDatagram::recv_from` * `UnixDatagram::recv` * `UnixDatagram::send_to` * `UnixDatagram::send` * `UnixDatagram::set_read_timeout` * `UnixDatagram::set_write_timeout` * `UnixDatagram::read_timeout` * `UnixDatagram::write_timeout` * `UnixDatagram::set_nonblocking` * `UnixDatagram::take_error` * `UnixDatagram::shutdown` * RawFd impls for `UnixDatagram` * `{BTree,Hash}Map::values_mut` * `<[_]>::binary_search_by_key` Deprecated: * `StaticCondvar` - this, and all other static synchronization primitives below, are usable today through the lazy-static crate on stable Rust today. Additionally, we'd like the non-static versions to be directly usable in a static context one day, so they're unlikely to be the final forms of the APIs in any case. * `CONDVAR_INIT` * `StaticMutex` * `MUTEX_INIT` * `StaticRwLock` * `RWLOCK_INIT` * `iter::Peekable::is_empty` Closes #27717 Closes #27720 cc #27784 (but encode methods still exist) Closes #30014 Closes #30425 Closes #30449 Closes #31190 Closes #31399 Closes #31767 Closes #32111 Closes #32281 Closes #32312 Closes #32551 Closes #33018

2016-02-11bootstrap: Add directives to not double-link libsAlex Crichton-1/+2
Have all Cargo-built crates pass `--cfg cargobuild` and then add appropriate `#[cfg]` definitions to all crates to avoid linking anything if this is passed. This should help allow libstd to compile with both the makefiles and with Cargo.
2016-02-06Add the asmjs-unknown-emscripten triple. Add cfgs to libs.Brian Anderson-3/+5
Backtraces, and the compilation of libbacktrace for asmjs, are disabled. This port doesn't use jemalloc so, like pnacl, it disables jemalloc *for all targets* in the configure file. It disables stack protection.

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-1/+1
This commit is the standard API stabilization commit for the 1.6 release cycle. The list of issues and APIs below have all been through their cycle-long FCP and the libs team decisions are listed below Stabilized APIs * `Read::read_exact` * `ErrorKind::UnexpectedEof` (renamed from `UnexpectedEOF`) * libcore -- this was a bit of a nuanced stabilization, the crate itself is now marked as `#[stable]` and the methods appearing via traits for primitives like `char` and `str` are now also marked as stable. Note that the extension traits themeselves are marked as unstable as they're imported via the prelude. The `try!` macro was also moved from the standard library into libcore to have the same interface. Otherwise the functions all have copied stability from the standard library now. * The `#![no_std]` attribute * `fs::DirBuilder` * `fs::DirBuilder::new` * `fs::DirBuilder::recursive` * `fs::DirBuilder::create` * `os::unix::fs::DirBuilderExt` * `os::unix::fs::DirBuilderExt::mode` * `vec::Drain` * `vec::Vec::drain` * `string::Drain` * `string::String::drain` * `vec_deque::Drain` * `vec_deque::VecDeque::drain` * `collections::hash_map::Drain` * `collections::hash_map::HashMap::drain` * `collections::hash_set::Drain` * `collections::hash_set::HashSet::drain` * `collections::binary_heap::Drain` * `collections::binary_heap::BinaryHeap::drain` * `Vec::extend_from_slice` (renamed from `push_all`) * `Mutex::get_mut` * `Mutex::into_inner` * `RwLock::get_mut` * `RwLock::into_inner` * `Iterator::min_by_key` (renamed from `min_by`) * `Iterator::max_by_key` (renamed from `max_by`) Deprecated APIs * `ErrorKind::UnexpectedEOF` (renamed to `UnexpectedEof`) * `OsString::from_bytes` * `OsStr::to_cstring` * `OsStr::to_bytes` * `fs::walk_dir` and `fs::WalkDir` * `path::Components::peek` * `slice::bytes::MutableByteVector` * `slice::bytes::copy_memory` * `Vec::push_all` (renamed to `extend_from_slice`) * `Duration::span` * `IpAddr` * `SocketAddr::ip` * `Read::tee` * `io::Tee` * `Write::broadcast` * `io::Broadcast` * `Iterator::min_by` (renamed to `min_by_key`) * `Iterator::max_by` (renamed to `max_by_key`) * `net::lookup_addr` New APIs (still unstable) * `<[T]>::sort_by_key` (added to mirror `min_by_key`) Closes #27585 Closes #27704 Closes #27707 Closes #27710 Closes #27711 Closes #27727 Closes #27740 Closes #27744 Closes #27799 Closes #27801 cc #27801 (doesn't close as `Chars` is still unstable) Closes #28968

2015-11-16Ignore malformed environment strings like glibc doesTobias Bucher-8/+17
Otherwise, the iterator and the functions for getting specific environment variables might disagree, for environments like FOOBAR Variable names starting with equals sign are OK: glibc only interprets equals signs not in the first position as separators between variable name and variable value. Instead of skipping them entirely, a leading equals sign is interpreted to be part of the variable name.
2015-11-09std: Migrate to the new libcAlex Crichton-10/+12
* Delete `sys::unix::{c, sync}` as these are now all folded into libc itself * Update all references to use `libc` as a result. * Update all references to the new flat namespace. * Moves all windows bindings into sys::c
2015-11-06Auto merge of #29305 - alexcrichton:bad-getenv, r=brsonbors-22/+27
As discovered in #29298, `env::set_var("", "")` will panic, but it turns out that it *also* deadlocks on Unix systems. This happens because if a panic happens while holding the environment lock, we then go try to read RUST_BACKTRACE, grabbing the environment lock, causing a deadlock. Specifically, the changes made here are: * The environment lock is pushed into `std::sys` instead of `std::env`. This also only puts it in the Unix implementation, not Windows where the functions are already threadsafe. * The `std::sys` implementation now returns `io::Result` so panics are explicitly at the `std::env` level.

2015-09-11std: Internalize almost all of `std::rt`Alex Crichton-2/+2
This commit does some refactoring to make almost all of the `std::rt` private. Specifically, the following items are no longer part of its API: * DEFAULT_ERROR_CODE * backtrace * unwind * args * at_exit * cleanup * heap (this is just alloc::heap) * min_stack * util The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is an entry point for the `panic!` macro via the `begin_unwind` and `begin_unwind_fmt` reexports.

2015-08-28Use a different buffer doubling logic for `std::sys::os::getcwd`Barosl Lee-5/+7
Make `std::sys::os::getcwd` call `Vec::reserve(1)` followed by `Vec::set_len` to double the buffer. This is to align with other similar functions, such as: - `std::sys_common::io::read_to_end_uninitialized` - `std::sys::fs::readlink` Also, reduce the initial buffer size from 2048 to 512. The previous size was introduced with 4bc26ce in 2013, but it seems a bit excessive. This is probably because buffer doubling was not implemented back then.

2015-04-01std: Changing the meaning of the count to splitnAlex Crichton-1/+1
This commit is an implementation of [RFC 979][rfc] which changes the meaning of the count parameter to the `splitn` function on strings and slices.
