(https://github.com/tokio-rs/mio/commit/f5017fae8a3d3bb4b4cada25b01a2d76a406badc). 235 236## Fixes 237 238* Incorrect assumption of the layout of `std::net::SocketAddr`. Previously Mio 239 would assume that `SocketAddrV{4,6}` had the same layout as 240 `libc::sockaddr_in(6)`, however this is not guaranteed by the standard 241 library. 242 (https://github.com/tokio-rs/mio/commit/152e0751f0be1c9b0cbd6778645b76bcb0eba93c). 243* Also bumped the miow dependency to version 0.3.6 to solve the same problem as 244 above. 245 246# 0.7.5 247 248## Added 249 250* `TcpSocket::get_localaddr()` retrieves local address 251 (https://github.com/tokio-rs/mio/commit/b41a022b2242eef1969c70c8ba93e04c528dba47). 252* `TcpSocket::set_reuseport()` & `TcpSocket::get_reuseport()` configures and reads `SO_REUSEPORT` 253 (https://github.com/tokio-rs/mio/commit/183bbe409ab69cbf9db41d0263b41ec86202d9a0). 254* `unix:pipe()` a wrapper around pipe(2) sys call 255 (https://github.com/tokio-rs/mio/commit/2b7c0967a7362303946deb3d4ca2ae507af6c72d). 256* Add a check that a single Waker is active per Poll instance (only in debug mode) 257 (https://github.com/tokio-rs/mio/commit/f4874f28b32efcf4841691884c65a89734d96a56). 258* Added `Interest:remove()` 259 (https://github.com/tokio-rs/mio/commit/b8639c3d9ac07bb7e2e27685680c8a6510fa1357). 260 261# 0.7.4 262 263## Fixes 264 265* lost "socket closed" events on windows 266 (https://github.com/tokio-rs/mio/commit/50c299aca56c4a26e5ed20c283007239fbe6a7a7). 267 268## Added 269 270* `TcpSocket::set_linger()` configures SO_LINGER 271 (https://github.com/tokio-rs/mio/commit/3b4096565c1a879f651b8f8282ecdcbdbd5c92d3). 272 273# 0.7.3 274 275## Added 276 277* `TcpSocket` for configuring a TCP socket before connecting or listening 278 (https://github.com/tokio-rs/mio/commit/5b09e60d0f64419b989bda88c86a3147334a03b3). 279 280# 0.7.2 281 282## Added 283 284* Windows named pipe support. 285 (https://github.com/tokio-rs/mio/commit/52e8c2220e87696d20f13561402bcaabba4136ed). 286 287# 0.7.1 288 289## Reduced support for 32-bit Apple targets 290 291In January 2020 Rust reduced its support for 32-bit Apple targets 292(https://blog.rust-lang.org/2020/01/03/reducing-support-for-32-bit-apple-targets.html). 293Starting with v0.7.1 Mio will do the same as we're no longer checking 32 bit 294iOS/macOS on our CI. 295 296## Added 297 298* Support for illumos 299 (https://github.com/tokio-rs/mio/commit/976f2354d0e8fbbb64fba3bf017d7131f9c369a0). 300* Report `epoll(2)`'s `EPOLLERR` event as `Event::is_write_closed` if it's the 301 only event 302 (https://github.com/tokio-rs/mio/commit/0c77b5712d675eeb9bd43928b5dd7d22b2c7ac0c). 303* Optimised event::Iter::{size_hint, count} 304 (https://github.com/tokio-rs/mio/commit/40df934a11b05233a7796c4de19a4ee06bc4e03e). 305 306## Fixed 307 308* Work around Linux kernel < 2.6.37 bug on 32-bits making timeouts longer then 309 ~30 minutes effectively infinite 310 (https://github.com/tokio-rs/mio/commit/d555991f5ee81f6c1eec0fe481557d3d5b8d5ff4). 311* Set `SO_NOSIGPIPE` on all sockets (not just UDP) on for Apple targets 312 (https://github.com/tokio-rs/mio/commit/b8bbdcb0d3236f4c4acb257996d42a88dc9987d9). 313* Properly handle `POLL_ABORT` on Windows 314 (https://github.com/tokio-rs/mio/commit/a98da62b3ed1eeed1770aaca12f46d647e4fa749). 315* Improved error handling around failing `SIO_BASE_HANDLE` calls on Windows 316 (https://github.com/tokio-rs/mio/commit/b15fc18458a79ef8a51f73effa92548650f4e5dc). 317 318## Changed 319 320* On NetBSD we now use `accept4(2)` 321 (https://github.com/tokio-rs/mio/commit/4e306addc7144f2e02a7e8397c220b179a006a19). 322* The package uploaded to crates.io should be slightly smaller 323 (https://github.com/tokio-rs/mio/commit/eef8d3b9500bc0db957cd1ac68ee128ebc68351f). 324 325## Removed 326 327* Dependency on `lazy_static` on Windows 328 (https://github.com/tokio-rs/mio/commit/57e4c2a8ac153bc7bb87829e22cf0a21e3927e8a). 329 330# 0.7.0 331 332Version 0.7 of Mio contains various major changes compared to version 0.6. 333Overall a large number of API changes have been made to reduce the complexity of 334the implementation and remove overhead where possible. 335 336Please refer to the [blog post about 3370.7-alpha.1](https://tokio.rs/blog/2019-12-mio-v0.7-alpha.1/) for additional 338information. 339 340## Added 341 342* `Interest` structure that replaces `Ready` in registering event sources. 343* `Registry` structure that separates the registering and polling functionality. 344* `Waker` structure that allows another thread to wake a thread polling `Poll`. 345* Unix Domain Socket (UDS) types: `UnixDatagram`, `UnixListener` and 346 `UnixStream`. 347 348## Removed 349 350* All code deprecated in 0.6 was removed in 0.7. 351* Support for Fuchsia was removed as the code was unmaintained. 352* Support for Bitrig was removed, rustc dropped support for it also. 353* `UnixReady` was merged into `Ready`. 354* Custom user-space readiness queue was removed, this includes the public 355 `Registration` and `SetReadiness` types. 356* `PollOpt` was removed and all registrations use edge-triggers. See the upgrade 357 guide on how to process event using edge-triggers. 358* The network types (types in the `net` module) now support only the same API as 359 found in the standard library, various methods on the types were removed. 360* `TcpStream` now supports vectored I/O. 361* `Poll::poll_interruptible` was removed. Instead `Poll::poll` will now return 362 an error if one occurs. 363* `From<usize>` is removed from `Token`, the internal field is still public, so 364 `Token(my_token)` can still be used. 365 366## Changed 367 368* Various documentation improvements were made around correct usage of `Poll` 369 and registered event sources. It is recommended to reread the documentation of 370 at least `event::Source` and `Poll`. 371* Mio now uses Rust 2018 and rustfmt for all code. 372* `Event` was changed to be a wrapper around the OS event. This means it can be 373 significantly larger on some OSes. 374* `Ready` was removed and replaced with various `is_*` methods on `Event`. For 375 example instead checking for readable readiness using 376 `Event::ready().is_readable()`, you would call `Event::is_readable()`. 377* `Ready::is_hup` was removed in favour of `Event::is_read_closed` and 378 `Event::is_write_closed`. 379* The Iterator implementation of `Events` was changed to return `&Event`. 380* `Evented` was renamed to `event::Source` and now takes mutable reference to 381 the source. 382* Minimum supported Rust version was increased to 1.39. 383* By default Mio now uses a shim implementation. To enable the full 384 implementation, that uses the OS, enable the `os-oll` feature. To enable the 385 network types use `tcp`, `udp` and/or `uds`. For more documentation on the 386 features see the `feature` module in the API documentation (requires the 387 `extra-docs` feature). 388* The entire Windows implementation was rewritten. 389* Various optimisation were made to reduce the number of system calls in 390 creating and using sockets, e.g. making use of `accept4(2)`. 391* The `fmt::Debug` implementation of `Events` is now actually useful as it 392 prints all `Event`s. 393 394# 0.6.23 (Dec 01, 2020) 395 396### Changed 397- **MSRV**: Increased the MSRV from 1.18.0 (Jun 8, 2017) to 1.31.0 (Dec 6, 398 2018) 399 (https://github.com/tokio-rs/mio/commit/4879e0d32ddfd98e762fc87240e594a3ad8fca30). 400 401### Fixed 402- Work around Linux kernel < 2.6.37 bug on 32-bits making timeouts longer then 403 ~30 minutes effectively infinite 404 (https://github.com/tokio-rs/mio/commit/e7cba59950e9c9fa6194e29b5b1e72029e3df455). 405- Update miow and net2 depedencies to get rid of invalid memory layout assumption 406 (https://github.com/tokio-rs/mio/commit/13f02ac0a86d7c0c0001e5ff8960a0b4340d075c). 407 408# 0.6.22 (May 01, 2020) 409 410### Added 411- Add support for illumos target (#1294) 412 413# 0.6.21 (November 27, 2019) 414 415### Fixed 416- remove `=` dependency on `cfg-if`. 417 418# 0.6.20 (November 21, 2019) 419 420### Fixed 421- Use default IOCP concurrency value (#1161). 422- setting FD_CLOEXEC in pipe (#1095). 423 424# 0.6.19 (May 28, 2018) 425 426### Fixed 427- Do not trigger HUP events on kqueue platforms (#958). 428 429# 0.6.18 (May 24, 2018) 430 431### Fixed 432- Fix compilation on kqueue platforms with 32bit C long (#948). 433 434# 0.6.17 (May 15, 2018) 435 436### Fixed 437- Don't report `RDHUP` as `HUP` (#939) 438- Fix lazycell related compilation issues. 439- Fix EPOLLPRI conflicting with READABLE 440- Abort process on ref count overflows 441 442### Added 443- Define PRI on all targets 444 445# 0.6.16 (September 5, 2018) 446 447* Add EPOLLPRI readiness to UnixReady on supported platforms (#867) 448* Reduce spurious awaken calls (#875) 449 450# 0.6.15 (July 3, 2018) 451 452* Implement `Evented` for containers (#840). 453* Fix android-aarch64 build (#850). 454 455# 0.6.14 (March 8, 2018) 456 457* Add `Poll::poll_interruptible` (#811) 458* Add `Ready::all` and `usize` conversions (#825) 459 460# 0.6.13 (February 5, 2018) 461 462* Fix build on DragonFlyBSD. 463* Add `TcpListener::from_std` that does not require the socket addr. 464* Deprecate `TcpListener::from_listener` in favor of from_std. 465 466# 0.6.12 (January 5, 2018) 467 468* Add `TcpStream::peek` function (#773). 469* Raise minimum Rust version to 1.18.0. 470* `Poll`: retry select() when interrupted by a signal (#742). 471* Deprecate `Events` index access (#713). 472* Add `Events::clear` (#782). 473* Add support for `lio_listio` (#780). 474 475# 0.6.11 (October 25, 2017) 476 477* Allow register to take empty interest (#640). 478* Fix bug with TCP errors on windows (#725). 479* Add TcpListener::accept_std (#733). 480* Update IoVec to fix soundness bug -- includes behavior change.
