2015-06-22Fix build on Android API levels below 21Geoffrey Thomas-0/+10
signal(), sigemptyset(), and sigaddset() are only available as inline functions until Android API 21. liblibc already handles signal() appropriately, so drop it from c.rs; translate sigemptyset() and sigaddset() (which is only used in a test) by hand from the C inlines. We probably want to revert this commit when we bump Android API level.
2015-06-22sys/unix/process: Reset signal behavior before execGeoffrey Thomas-0/+74
Make sure that child processes don't get affected by libstd's desire to ignore SIGPIPE, nor a third-party library's signal mask (which is needed to use either a signal-handling thread correctly or to use signalfd / kqueue correctly).
2015-06-19liblibc: Fix prototype of functions taking `char *const argv[]`Geoffrey Thomas-1/+1
The execv family of functions do not modify their arguments, so they do not need mutable pointers. The C prototypes take a constant array of mutable C-strings, but that's a legacy quirk from before C had const (since C string literals have type `char *`). The Rust prototypes had `*mut` in the wrong place, anyway: to match the C prototypes, it should have been `*const *mut c_char`. But it is safe to pass constant strings (like string literals) to these functions. getopt is a special case, since GNU getopt modifies its arguments despite the `const` claim in the prototype. It is apparently only well-defined to call getopt on the actual argc and argv parameters passed to main, anyway. Change it to take `*mut *mut c_char` for an attempt at safety, but probably nobody should be using it from Rust, since there's no great way to get at the parameters as passed to main. Also fix the one caller of execvp in libstd, which now no longer needs an unsafe cast. Fixes #16290.
2015-06-09std: Tweak process raising/lowering implementationsAlex Crichton-22/+11
* Slate these features to be stable in 1.2 instead of 1.1 (not being backported) * Have the `FromRawFd` implementations follow the contract of the `FromRawFd` trait by taking ownership of the primitive specified. * Refactor the implementations slightly to remove the `unreachable!` blocks as well as separating the stdio representation of `std::process` from `std::sys::process`.
2015-05-29Auto merge of #25494 - alexcrichton:stdio-from-raw, r=aturonbors-0/+13
This commit implements a number of standard traits for the standard library's process I/O handles. The `FromRaw{Fd,Handle}` traits are now implemented for the `Stdio` type and the `AsRaw{Fd,Handle}` traits are now implemented for the `Child{Stdout,Stdin,Stderr}` types. The stability markers for these implementations mention that they are stable for 1.1 as I will nominate this commit for cherry-picking to beta.
2015-05-16std: Implement lowering and raising for process IOAlex Crichton-0/+13
This commit implements a number of standard traits for the standard library's process I/O handles. The `FromRaw{Fd,Handle}` traits are now implemented for the `Stdio` type and the `AsRaw{Fd,Handle}` traits are now implemented for the `Child{Stdout,Stdin,Stderr}` types. Additionally this implements the `AsRawHandle` trait for `Child` on Windows. The stability markers for these implementations mention that they are stable for 1.1 as I will nominate this commit for cherry-picking to beta.
2015-05-16std: Add an unstable method Child::idAlex Crichton-0/+4
This commits adds a method to the `std::process` module to get the process identifier of the child as a `u32`. On Windows the underlying identifier is already a `u32`, and on Unix the type is typically defined as `c_int` (`i32` for almost all our supported platforms), but the actually pid is normally a small positive number. Eventually we may add functions to load information about a process based on its identifier or the ability to terminate a process based on its identifier, but for now this function should enable this sort of functionality to exist outside the standard library.
2015-05-07std: Rename sys::foo2 modules to sys::fooAlex Crichton-0/+414

2015-03-13Auto merge of #23229 - aturon:stab-path, r=alexcrichtonbors-1/+1
This commit stabilizes essentially all of the new `std::path` API. The API itself is changed in a couple of ways (which brings it in closer alignment with the RFC): * `.` components are now normalized away, unless they appear at the start of a path. This in turn effects the semantics of e.g. asking for the file name of `foo/` or `foo/.`, both of which yield `Some("foo")` now. This semantics is what the original RFC specified, and is also desirable given early experience rolling out the new API. * The `parent` method is now `without_file` and succeeds if, and only if, `file_name` is `Some(_)`. That means, in particular, that it fails for a path like `foo/../`. This change affects `pop` as well. In addition, the `old_path` module is now deprecated. [breaking-change] r? @alexcrichton

2015-02-18std: Stabilize the `hash` moduleAlex Crichton-0/+249
This commit is an implementation of [RFC 823][rfc] which is another pass over the `std::hash` module for stabilization. The contents of the module were not entirely marked stable, but some portions which remained quite similar to the previous incarnation are now marked `#[stable]`. Specifically: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0823-hash-simplification.md * `std::hash` is now stable (the name) * `Hash` is now stable * `Hash::hash` is now stable * `Hasher` is now stable * `SipHasher` is now stable * `SipHasher::new` and `new_with_keys` are now stable * `Hasher for SipHasher` is now stable * Many `Hash` implementations are now stable All other portions of the `hash` module remain `#[unstable]` as they are less commonly used and were recently redesigned. This commit is a breaking change due to the modifications to the `std::hash` API and more details can be found on the [RFC][rfc]. Closes #22467 [breaking-change]

2015-02-13Add std::processAaron Turon-0/+6
Per [RFC 579](https://github.com/rust-lang/rfcs/pull/579), this commit adds a new `std::process` module. This module is largely based on the existing `std::old_io::process` module, but refactors the API to use `OsStr` and other new standards set out by IO reform. The existing module is not yet deprecated, to allow for the new API to get a bit of testing before a mass migration to it.

As part of [RFC 474](https://github.com/rust-lang/rfcs/pull/474), this commit renames `std::path` to `std::old_path`, leaving the existing path API in place to ease migration to the new one. Updating should be as simple as adjusting imports, and the prelude still maps to the old path APIs for now. [breaking-change]

2015-02-01std: Add a new `env` moduleAlex Crichton-13/+1
This is an implementation of [RFC 578][rfc] which adds a new `std::env` module to replace most of the functionality in the current `std::os` module. More details can be found in the RFC itself, but as a summary the following methods have all been deprecated: [rfc]: https://github.com/rust-lang/rfcs/pull/578 * `os::args_as_bytes` => `env::args` * `os::args` => `env::args` * `os::consts` => `env::consts` * `os::dll_filename` => no replacement, use `env::consts` directly * `os::page_size` => `env::page_size` * `os::make_absolute` => use `env::current_dir` + `join` instead * `os::getcwd` => `env::current_dir` * `os::change_dir` => `env::set_current_dir` * `os::homedir` => `env::home_dir` * `os::tmpdir` => `env::temp_dir` * `os::join_paths` => `env::join_paths` * `os::split_paths` => `env::split_paths` * `os::self_exe_name` => `env::current_exe` * `os::self_exe_path` => use `env::current_exe` + `pop` * `os::set_exit_status` => `env::set_exit_status` * `os::get_exit_status` => `env::get_exit_status` * `os::env` => `env::vars` * `os::env_as_bytes` => `env::vars` * `os::getenv` => `env::var` or `env::var_string` * `os::getenv_as_bytes` => `env::var` * `os::setenv` => `env::set_var` * `os::unsetenv` => `env::remove_var` Many function signatures have also been tweaked for various purposes, but the main changes were: * `Vec`-returning APIs now all return iterators instead * All APIs are now centered around `OsString` instead of `Vec<u8>` or `String`. There is currently on convenience API, `env::var_string`, which can be used to get the value of an environment variable as a unicode `String`. All old APIs are `#[deprecated]` in-place and will remain for some time to allow for migrations. The semantics of the APIs have been tweaked slightly with regard to dealing with invalid unicode (panic instead of replacement). The new `std::env` module is all contained within the `env` feature, so crates must add the following to access the new APIs: #![feature(env)] [breaking-change]

2015-01-07std: Stabilize the std::hash moduleAlex Crichton-4/+5
This commit aims to prepare the `std::hash` module for alpha by formalizing its current interface whileholding off on adding `#[stable]` to the new APIs. The current usage with the `HashMap` and `HashSet` types is also reconciled by separating out composable parts of the design. The primary goal of this slight redesign is to separate the concepts of a hasher's state from a hashing algorithm itself. The primary change of this commit is to separate the `Hasher` trait into a `Hasher` and a `HashState` trait. Conceptually the old `Hasher` trait was actually just a factory for various states, but hashing had very little control over how these states were used. Additionally the old `Hasher` trait was actually fairly unrelated to hashing. This commit redesigns the existing `Hasher` trait to match what the notion of a `Hasher` normally implies with the following definition: trait Hasher { type Output; fn reset(&mut self); fn finish(&self) -> Output; } This `Hasher` trait emphasizes that hashing algorithms may produce outputs other than a `u64`, so the output type is made generic. Other than that, however, very little is assumed about a particular hasher. It is left up to implementors to provide specific methods or trait implementations to feed data into a hasher. The corresponding `Hash` trait becomes: trait Hash<H: Hasher> { fn hash(&self, &mut H); } The old default of `SipState` was removed from this trait as it's not something that we're willing to stabilize until the end of time, but the type parameter is always required to implement `Hasher`. Note that the type parameter `H` remains on the trait to enable multidispatch for specialization of hashing for particular hashers. Note that `Writer` is not mentioned in either of `Hash` or `Hasher`, it is simply used as part `derive` and the implementations for all primitive types. With these definitions, the old `Hasher` trait is realized as a new `HashState` trait in the `collections::hash_state` module as an unstable addition for now. The current definition looks like: trait HashState { type Hasher: Hasher; fn hasher(&self) -> Hasher; } The purpose of this trait is to emphasize that the one piece of functionality for implementors is that new instances of `Hasher` can be created. This conceptually represents the two keys from which more instances of a `SipHasher` can be created, and a `HashState` is what's stored in a `HashMap`, not a `Hasher`. Implementors of custom hash algorithms should implement the `Hasher` trait, and only hash algorithms intended for use in hash maps need to implement or worry about the `HashState` trait. The entire module and `HashState` infrastructure remains `#[unstable]` due to it being recently redesigned, but some other stability decision made for the `std::hash` module are: * The `Writer` trait remains `#[experimental]` as it's intended to be replaced with an `io::Writer` (more details soon). * The top-level `hash` function is `#[unstable]` as it is intended to be generic over the hashing algorithm instead of hardwired to `SipHasher` * The inner `sip` module is now private as its one export, `SipHasher` is reexported in the `hash` module. And finally, a few changes were made to the default parameters on `HashMap`. * The `RandomSipHasher` default type parameter was renamed to `RandomState`. This renaming emphasizes that it is not a hasher, but rather just state to generate hashers. It also moves away from the name "sip" as it may not always be implemented as `SipHasher`. This type lives in the `std::collections::hash_map` module as `#[unstable]` * The associated `Hasher` type of `RandomState` is creatively called... `Hasher`! This concrete structure lives next to `RandomState` as an implemenation of the "default hashing algorithm" used for a `HashMap`. Under the hood this is currently implemented as `SipHasher`, but it draws an explicit interface for now and allows us to modify the implementation over time if necessary. There are many breaking changes outlined above, and as a result this commit is a: [breaking-change]
2015-01-06core: split into fmt::Show and fmt::StringSean McArthur-7/+7
fmt::Show is for debugging, and can and should be implemented for all public types. This trait is used with `{:?}` syntax. There still exists #[derive(Show)]. fmt::String is for types that faithfully be represented as a String. Because of this, there is no way to derive fmt::String, all implementations must be purposeful. It is used by the default format syntax, `{}`. This will break most instances of `{}`, since that now requires the type to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the correct fix. Types that were being printed specifically for users should receive a fmt::String implementation to fix this. Part of #20013 [breaking-change]
2015-01-05std: Redesign c_str and c_vecAlex Crichton-3/+3
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.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-9/+10
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.
