2019-11-29Format libstd with rustfmtDavid Tolnay-8/+10
This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libstd. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference

2016-05-24std: Stabilize APIs for the 1.10 releaseAlex Crichton-0/+2
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

This commit cleans out a large amount of deprecated APIs from the standard library and some of the facade crates as well, updating all users in the compiler and in tests as it goes along.
2015-03-05std: Stabilize the `ffi` moduleAlex Crichton-4/+7
The two main sub-modules, `c_str` and `os_str`, have now had some time to bake in the standard library. This commits performs a sweep over the modules adding various stability tags. The following APIs are now marked `#[stable]` * `OsString` * `OsStr` * `OsString::from_string` * `OsString::from_str` * `OsString::new` * `OsString::into_string` * `OsString::push` (renamed from `push_os_str`, added an `AsOsStr` bound) * various trait implementations for `OsString` * `OsStr::from_str` * `OsStr::to_str` * `OsStr::to_string_lossy` * `OsStr::to_os_string` * various trait implementations for `OsStr` * `CString` * `CStr` * `NulError` * `CString::new` - this API's implementation may change as a result of rust-lang/rfcs#912 but the usage of `CString::new(thing)` looks like it is unlikely to change. Additionally, the `IntoBytes` bound is also likely to change but the set of implementors for the trait will not change (despite the trait perhaps being renamed). * `CString::from_vec_unchecked` * `CString::as_bytes` * `CString::as_bytes_with_nul` * `NulError::nul_position` * `NulError::into_vec` * `CStr::from_ptr` * `CStr::as_ptr` * `CStr::to_bytes` * `CStr::to_bytes_with_nul` * various trait implementations for `CStr` The following APIs remain `#[unstable]` * `OsStr*Ext` traits remain unstable as the organization of `os::platform` is uncertain still and the traits may change location. * `AsOsStr` remains unstable as generic conversion traits are likely to be rethought soon. The following APIs were deprecated * `OsString::push_os_str` is now called `push` and takes `T: AsOsStr` instead (a superset of the previous functionality).
2015-02-18std: Implement CString-related RFCsAlex Crichton-1/+3
This commit is an implementation of [RFC 592][r592] and [RFC 840][r840]. These two RFCs tweak the behavior of `CString` and add a new `CStr` unsized slice type to the module. [r592]: https://github.com/rust-lang/rfcs/blob/master/text/0592-c-str-deref.md [r840]: https://github.com/rust-lang/rfcs/blob/master/text/0840-no-panic-in-c-string.md The new `CStr` type is only constructable via two methods: 1. By `deref`'ing from a `CString` 2. Unsafely via `CStr::from_ptr` The purpose of `CStr` is to be an unsized type which is a thin pointer to a `libc::c_char` (currently it is a fat pointer slice due to implementation limitations). Strings from C can be safely represented with a `CStr` and an appropriate lifetime as well. Consumers of `&CString` should now consume `&CStr` instead to allow producers to pass in C-originating strings instead of just Rust-allocated strings. A new constructor was added to `CString`, `new`, which takes `T: IntoBytes` instead of separate `from_slice` and `from_vec` methods (both have been deprecated in favor of `new`). The `new` method returns a `Result` instead of panicking. The error variant contains the relevant information about where the error happened and bytes (if present). Conversions are provided to the `io::Error` and `old_io::IoError` types via the `FromError` trait which translate to `InvalidInput`. This is a breaking change due to the modification of existing `#[unstable]` APIs and new deprecation, and more detailed information can be found in the two RFCs. Notable breakage includes: * All construction of `CString` now needs to use `new` and handle the outgoing `Result`. * Usage of `CString` as a byte slice now explicitly needs a `.as_bytes()` call. * The `as_slice*` methods have been removed in favor of just having the `as_bytes*` methods. Closes #22469 Closes #22470 [breaking-change]
2015-02-03Add new path moduleAaron Turon-0/+1
Implements [RFC 474](https://github.com/rust-lang/rfcs/pull/474); see that RFC for details/motivation for this change. This initial commit does not include additional normalization or platform-specific path extensions. These will be done in follow up commits or PRs.
2015-02-01std: Add a new `env` moduleAlex Crichton-1/+6
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]

2015-01-24Add ffi::OsString and OsStrAaron Turon-0/+5
Per [RFC 517](https://github.com/rust-lang/rfcs/pull/575/), this commit introduces platform-native strings. The API is essentially as described in the RFC. The WTF-8 implementation is adapted from @SimonSapin's [implementation](https://github.com/SimonSapin/rust-wtf8). To make this work, some encodign and decoding functionality in `libcore` is now exported in a "raw" fashion reusable for WTF-8. These exports are *not* reexported in `std`, nor are they stable.

2015-01-05std: Redesign c_str and c_vecAlex Crichton-0/+20
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. This is a: [breaking-change] Closes #20444
