# Change Log

All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).

## [Unreleased]

### Changed
- `pipe2` now calls `libc::pipe2` where available. Previously it was emulated
  using `pipe`, which meant that setting `O_CLOEXEC` was not atomic.

## [0.7.0] 2016-09-09

### Added
- Added `lseek` and `lseek64` in `::nix::unistd`
  ([#377](https://github.com/nix-rust/nix/pull/377))
- Added `mkdir` and `getcwd` in `::nix::unistd`
  ([#416](https://github.com/nix-rust/nix/pull/416))
- Added accessors `sigmask_mut` and `sigmask` to `UContext` in
  `::nix::ucontext`.
  ([#370](https://github.com/nix-rust/nix/pull/370))
- Added `WUNTRACED` to `WaitPidFlag` in `::nix::sys::wait` for non-_linux_
  targets.
  ([#379](https://github.com/nix-rust/nix/pull/379))
- Added new module `::nix::sys::reboot` with enumeration `RebootMode` and
  functions `reboot` and `set_cad_enabled`. Currently for _linux_ only.
  ([#386](https://github.com/nix-rust/nix/pull/386))
- `FdSet` in `::nix::sys::select` now also implements `Clone`.
  ([#405](https://github.com/nix-rust/nix/pull/405))
- Added `F_FULLFSYNC` to `FcntlArg` in `::nix::fcntl` for _apple_ targets.
  ([#407](https://github.com/nix-rust/nix/pull/407))
- Added `CpuSet::unset` in `::nix::sched`.
  ([#402](https://github.com/nix-rust/nix/pull/402))
- Added constructor method `new()` to `PollFd` in `::nix::poll`, in order to
  allow creation of objects, after removing public access to members.
  ([#399](https://github.com/nix-rust/nix/pull/399))
- Added method `revents()` to `PollFd` in `::nix::poll`, in order to provide
  read access to formerly public member `revents`.
  ([#399](https://github.com/nix-rust/nix/pull/399))
- Added `MSG_CMSG_CLOEXEC` to `MsgFlags` in `::nix::sys::socket` for _linux_ only.
  ([#422](https://github.com/nix-rust/nix/pull/422))

### Changed
- Replaced the reexported integer constants for signals by the enumeration
  `Signal` in `::nix::sys::signal`.
  ([#362](https://github.com/nix-rust/nix/pull/362))
- Renamed `EventFdFlag` to `EfdFlags` in `::nix::sys::eventfd`.
  ([#383](https://github.com/nix-rust/nix/pull/383))
- Changed the result types of `CpuSet::is_set` and `CpuSet::set` in
  `::nix::sched` to `Result<bool>` and `Result<()>`, respectively. They now
  return `EINVAL`, if an invalid argument for the `field` parameter is passed.
  ([#402](https://github.com/nix-rust/nix/pull/402))
- `MqAttr` in `::nix::mqueue` is now an opaque proxy for `::libc::mq_attr`,
  which has the same structure as the old `MqAttr`. The field `mq_flags` of
  `::libc::mq_attr` is readable using the new method `flags()` of `MqAttr`.
  `MqAttr` also no longer implements `Debug`.
  ([#0](https://github.com/nix-rust/nix/pull/0))
- The parameter `msq_prio` of `mq_receive` with type `u32` in `::nix::mqueue`
  was replaced by a parameter named `msg_prio` with type `&mut u32`, so that
  the message priority can be obtained by the caller.
  ([#0](https://github.com/nix-rust/nix/pull/0))
- The type alias `MQd` in `::nix::queue` was replaced by the type alias
  `libc::mqd_t`, both of which are aliases for the same type.
  ([#0](https://github.com/nix-rust/nix/pull/0))

### Removed
- Type alias `SigNum` from `::nix::sys::signal`.
  ([#362](https://github.com/nix-rust/nix/pull/362))
- Type alias `CpuMask` from `::nix::shed`.
  ([#402](https://github.com/nix-rust/nix/pull/402))
- Removed public fields from `PollFd` in `::nix::poll`. (See also added method
  `revents()`.
  ([#399](https://github.com/nix-rust/nix/pull/399))

### Fixed
- Fixed the build problem for NetBSD (Note, that we currently do not support
  it, so it might already be broken again).
  ([#389](https://github.com/nix-rust/nix/pull/389))
- Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg
  functions on that same OS.
  ([#397](https://github.com/nix-rust/nix/pull/397))
