# Change Log
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## [Unreleased]
### Added
- Added support for POSIX AIO
([#483](https://github.com/nix-rust/nix/pull/483))
- Added support for XNU system control sockets
([#478](https://github.com/nix-rust/nix/pull/478))
- Added support for `ioctl` calls on BSD platforms
([#478](https://github.com/nix-rust/nix/pull/478))
- Added struct `TimeSpec`
([#475](https://github.com/nix-rust/nix/pull/475))
([#483](https://github.com/nix-rust/nix/pull/483))
- Added complete definitions for all kqueue-related constants on all supported
OSes
([#415](https://github.com/nix-rust/nix/pull/415))
- Added function `epoll_create1` and bitflags `EpollCreateFlags` in
`::nix::sys::epoll` in order to support `::libc::epoll_create1`.
([#410](https://github.com/nix-rust/nix/pull/410))
- Added `setresuid` and `setresgid` for Linux in `::nix::unistd`
([#448](https://github.com/nix-rust/nix/pull/448))
- Added `getpgid` in `::nix::unistd`
([#433](https://github.com/nix-rust/nix/pull/433))
- Added `tcgetpgrp` and `tcsetpgrp` in `::nix::unistd`
([#451](https://github.com/nix-rust/nix/pull/451))
- Added `CLONE_NEWCGROUP` in `::nix::sched`
([#457](https://github.com/nix-rust/nix/pull/457))
- Added `getpgrp` in `::nix::unistd`
([#491](https://github.com/nix-rust/nix/pull/491))
- Added `fchdir` in `::nix::unistd`
([#497](https://github.com/nix-rust/nix/pull/497))
### Changed
- `epoll_ctl` now could accept None as argument `event`
when op is `EpollOp::EpollCtlDel`.
([#480](https://github.com/nix-rust/nix/pull/480))
- Removed the `bad` keyword from the `ioctl!` macro
([#478](https://github.com/nix-rust/nix/pull/478))
- Changed `TimeVal` into an opaque Newtype
([#475](https://github.com/nix-rust/nix/pull/475))
- `kill`'s signature, defined in `::nix::sys::signal`, changed, so that the
signal parameter has type `T: Into<Option<Signal>>`. `None` as an argument
for that parameter will result in a 0 passed to libc's `kill`, while a
`Some`-argument will result in the previous behavior for the contained
`Signal`.
([#445](https://github.com/nix-rust/nix/pull/445))
- The minimum supported version of rustc is now 1.7.0.
([#444](https://github.com/nix-rust/nix/pull/444))
- Changed `KEvent` to an opaque structure that may only be modified by its
constructor and the `ev_set` method.
([#415](https://github.com/nix-rust/nix/pull/415))
([#442](https://github.com/nix-rust/nix/pull/442))
([#463](https://github.com/nix-rust/nix/pull/463))
- `pipe2` now calls `libc::pipe2` where available. Previously it was emulated
using `pipe`, which meant that setting `O_CLOEXEC` was not atomic.
([#427](https://github.com/nix-rust/nix/pull/427))
- Renamed `EpollEventKind` to `EpollFlags` in `::nix::sys::epoll` in order for
it to conform with our conventions.
([#410](https://github.com/nix-rust/nix/pull/410))
- `EpollEvent` in `::nix::sys::epoll` is now an opaque proxy for
`::libc::epoll_event`. The formerly public field `events` is now be read-only
accessible with the new method `events()` of `EpollEvent`. Instances of
`EpollEvent` can be constructed using the new method `new()` of EpollEvent.
([#410](https://github.com/nix-rust/nix/pull/410))
- `SigFlags` in `::nix::sys::signal` has be renamed to `SigmaskHow` and its type
has changed from `bitflags` to `enum` in order to conform to our conventions.
([#460](https://github.com/nix-rust/nix/pull/460))
- `sethostname` now takes a `&str` instead of a `&[u8]` as this provides an API
that makes more sense in normal, correct usage of the API.
- `gethostname` previously did not expose the actual length of the hostname
written from the underlying system call at all. This has been updated to
return a `&CStr` within the provided buffer that is always properly
NUL-terminated (this is not guaranteed by the call with all platforms/libc
implementations).
### Fixed
- Fixed multiple issues with Unix domain sockets on non-Linux OSes
([#474](https://github.com/nix-rust/nix/pull/415))
- Fixed using kqueue with `EVFILT_USER` on FreeBSD
([#415](https://github.com/nix-rust/nix/pull/415))
- 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))
- Fixed an off-by-one bug in `UnixAddr::new_abstract` in `::nix::sys::socket`.
([#429](https://github.com/nix-rust/nix/pull/429))
- Fixed clone passing a potentially unaligned stack.
([#490](https://github.com/nix-rust/nix/pull/490))
## [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`.
([#392](https://github.com/nix-rust/nix/pull/392))
- 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.
([#392](https://github.com/nix-rust/nix/pull/392))
- 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.
([#392](https://github.com/nix-rust/nix/pull/392))
### 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))

- Added `SIGNALFD_SIGINFO_SIZE` in `::nix::sys::signalfd`.
([#309](https://github.com/nix-rust/nix/pull/309))

_linux_ only.
([#311](https://github.com/nix-rust/nix/pull/311))
- Added `EPOLLEXCLUSIVE` to `EpollEventKind` in `::nix::sys::epoll`.
([#330](https://github.com/nix-rust/nix/pull/330))

([#359](https://github.com/nix-rust/nix/pull/359))
- Added `clear` and `extend` functions to `SigSet`'s implementation in
`::nix::sys::signal`.
([#347](https://github.com/nix-rust/nix/pull/347))
- `sockaddr_storage_to_addr` in `::nix::sys::socket` now supports `sockaddr_nl`
on _linux_ and _android_.
([#366](https://github.com/nix-rust/nix/pull/366))
- Added support for `SO_ORIGINAL_DST` in `::nix::sys::socket` on _linux_.
([#367](https://github.com/nix-rust/nix/pull/367))

`SIGPWR` and `SIGSTKFLT` in `::nix::sys::signal` for non-_macos_ targets.
([#361](https://github.com/nix-rust/nix/pull/361))
