This commit is an implementation of [RFC 494][rfc] which removes the entire `std::c_vec` module and redesigns the `std::c_str` module as `std::ffi`. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0494-c_str-and-c_vec-stability.md The interface of the new `CString` is outlined in the linked RFC, the primary changes being: * The `ToCStr` trait is gone, meaning the `with_c_str` and `to_c_str` methods are now gone. These two methods are replaced with a `CString::from_slice` method. * The `CString` type is now just a wrapper around `Vec<u8>` with a static guarantee that there is a trailing nul byte with no internal nul bytes. This means that `CString` now implements `Deref<Target = [c_char]>`, which is where it gains most of its methods from. A few helper methods are added to acquire a slice of `u8` instead of `c_char`, as well as including a slice with the trailing nul byte if necessary. * All usage of non-owned `CString` values is now done via two functions inside of `std::ffi`, called `c_str_to_bytes` and `c_str_to_bytes_with_nul`. These functions are now the one method used to convert a `*const c_char` to a Rust slice of `u8`. Many more details, including newly deprecated methods, can be found linked in the RFC.

2015-01-05rollup merge of #20488: ltratt/nondeterministic_tempdirAlex Crichton-30/+44
The previous scheme made it possible for another user/attacker to cause the temporary directory creation scheme to panic. All you needed to know was the pid of the process you wanted to target ('other_pid') and the suffix it was using (let's pretend it's 'sfx') and then code such as this would, in essence, DOS it: for i in range(0u, 1001) { let tp = &Path::new(format!("/tmp/rs-{}-{}-sfx", other_pid, i)); match fs::mkdir(tp, io::USER_RWX) { _ => () } } Since the scheme only 1000 times to create a temporary directory before dying, the next time the attacked process called TempDir::new("sfx") after that would typically cause a panic. Of course, you don't necessarily need an attacker to cause such a DOS: creating 1000 temporary directories without closing any of the previous would be enough to DOS yourself. This patch broadly follows the OpenBSD implementation of mkstemp. It uses the operating system's random number generator to produce random directory names that are impractical to guess (and, just in case someone manages to do that, it retries creating the directory for a long time before giving up; OpenBSD retries INT_MAX times, although 1<<31 seems enough to thwart even the most patient attacker). As a small additional change while the file name is changing, this patch also makes the argument that TempDir::new takes a prefix rather than a suffix. This is because 1) it more closely matches what mkstemp and friends do 2) if you're going to have a deterministic part of a filename, you really want it at the beginning so that shell completion is useful.

2015-01-05Use $crate and macro reexport to reduce duplicated codeKeegan McAllister-1/+4
Many of libstd's macros are now re-exported from libcore and libcollections. Their libstd definitions have moved to a macros_stage0 module and can disappear after the next snapshot. Where the two crates had already diverged, I took the libstd versions as they're generally newer and better-tested. See e.g. d3c831b, which was a fix to libstd's assert_eq!() that didn't make it into libcore's. Fixes #16806.

The previous scheme made it possible for another user/attacker to cause the temporary directory creation scheme to panic.

2015-01-05Merge `UnicodeChar` and `CharExt`.Huon Wilson-1/+0
This "reexports" all the functionality of `core::char::CharExt` as methods on `unicode::u_char::UnicodeChar` (renamed to `CharExt`). Imports may need to be updated (one now just imports `unicode::CharExt`, or `std::char::CharExt` rather than two traits from either), so this is a [breaking-change]

2015-01-03Remove deprecated functionalityAlex Crichton-298/+13
This removes a large array of deprecated functionality, regardless of how recently it was deprecated. The purpose of this commit is to clean out the standard libraries and compiler for the upcoming alpha release. Some notable compiler changes were to enable warnings for all now-deprecated command line arguments (previously the deprecated versions were silently accepted) as well as removing deriving(Zero) entirely (the trait was removed). The distribution no longer contains the libtime or libregex_macros crates. Both of these have been deprecated for some time and are available externally.

2015-01-03auto merge of #20154 : P1start/rust/qualified-assoc-type-generics, ↵bors-2/+2
r=nikomatsakis This modifies `Parser::eat_lt` to always split up `<<`s, instead of doing so only when a lifetime name followed or the `force` parameter (now removed) was `true`. This is because `Foo<<TYPE` is now a valid start to a type, whereas previously only `Foo<<LIFETIME` was valid. This is a [breaking-change]. Change code that looks like this: ```rust let x = foo as bar << 13; ``` to use parentheses, like this: ```rust let x = (foo as bar) << 13; ``` Closes #17362.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-174/+195
This commit is an implementation of [RFC 503][rfc] which is a stabilization story for the prelude. Most of the RFC was directly applied, removing reexports. Some reexports are kept around, however: * `range` remains until range syntax has landed to reduce churn. * `Path` and `GenericPath` remain until path reform lands. This is done to prevent many imports of `GenericPath` which will soon be removed. * All `io` traits remain until I/O reform lands so imports can be rewritten all at once to `std::io::prelude::*`. This is a breaking change because many prelude reexports have been removed, and the RFC can be consulted for the exact list of removed reexports, as well as to find the locations of where to import them. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0503-prelude-stabilization.md [breaking-change] Closes #20068
2015-01-01std: Enforce Unicode in fmt::WriterAlex Crichton-4/+4
This commit is an implementation of [RFC 526][rfc] which is a change to alter the definition of the old `fmt::FormatWriter`. The new trait, renamed to `Writer`, now only exposes one method `write_str` in order to guarantee that all implementations of the formatting traits can only produce valid Unicode. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0526-fmt-text-writer.md One of the primary improvements of this patch is the performance of the `.to_string()` method by avoiding an almost-always redundant UTF-8 check. This is a breaking change due to the renaming of the trait as well as the loss of the `write` method, but migration paths should be relatively easy: * All usage of `write` should move to `write_str`. If truly binary data was being written in an implementation of `Show`, then it will need to use a different trait or an altogether different code path. * All usage of `write!` should continue to work as-is with no modifications. * All usage of `Show` where implementations just delegate to another should continue to work as-is. [breaking-change] Closes #20352
2015-01-01std: Second pass stabilization of syncAlex Crichton-11/+5
This pass performs a second pass of stabilization through the `std::sync` module, avoiding modules/types that are being handled in other PRs (e.g. mutexes, rwlocks, condvars, and channels). The following items are now stable * `sync::atomic` * `sync::atomic::ATOMIC_BOOL_INIT` (was `INIT_ATOMIC_BOOL`) * `sync::atomic::ATOMIC_INT_INIT` (was `INIT_ATOMIC_INT`) * `sync::atomic::ATOMIC_UINT_INIT` (was `INIT_ATOMIC_UINT`) * `sync::Once` * `sync::ONCE_INIT` * `sync::Once::call_once` (was `doit`) * C == `pthread_once(..)` * Boost == `call_once(..)` * Windows == `InitOnceExecuteOnce` * `sync::Barrier` * `sync::Barrier::new` * `sync::Barrier::wait` (now returns a `bool`) * `sync::Semaphore::new` * `sync::Semaphore::acquire` * `sync::Semaphore::release` The following items remain unstable * `sync::SemaphoreGuard` * `sync::Semaphore::access` - it's unclear how this relates to the poisoning story of mutexes. * `sync::TaskPool` - the semantics of a failing task and whether a thread is re-attached to a thread pool are somewhat unclear, and the utility of this type in `sync` is question with respect to the jobs of other primitives. This type will likely become stable or move out of the standard library over time. * `sync::Future` - futures as-is have yet to be deeply re-evaluated with the recent core changes to Rust's synchronization story, and will likely become stable in the future but are unstable until that time comes.

Users in the standard library have been audited in accordance to these new rules as well. Closes #20012
