Compare Source

Fixed

Compare Source

Added

Changed

• Made the log dependency optional behind the log feature flag (enabled by
  default). Users that disabled Mio's default features will now not see any
  logging from Mio, enabling the log feature will fix that. This was done in
  response to the log crate increasing it's MSRV to v1.60, see

v0.7.0

Compare Source

Version 0.7 of Mio contains various major changes compared to version 0.6.
Overall a large number of API changes have been made to reduce the complexity of
the implementation and remove overhead where possible.

Please refer to the blog post about
0.7-alpha.1 for additional
information.

Added

• Interest structure that replaces Ready in registering event sources.
• Registry structure that separates the registering and polling functionality.
• Waker structure that allows another thread to wake a thread polling Poll.
• Unix Domain Socket (UDS) types: UnixDatagram, UnixListener and
  UnixStream.

Removed

• All code deprecated in 0.6 was removed in 0.7.
• Support for Fuchsia was removed as the code was unmaintained.
• Support for Bitrig was removed, rustc dropped support for it also.
• UnixReady was merged into Ready.
• Custom user-space readiness queue was removed, this includes the public
  Registration and SetReadiness types.
• PollOpt was removed and all registrations use edge-triggers. See the upgrade
  guide on how to process event using edge-triggers.
• The network types (types in the net module) now support only the same API as
  found in the standard library, various methods on the types were removed.
• TcpStream now supports vectored I/O.
• Poll::poll_interruptible was removed. Instead Poll::poll will now return
  an error if one occurs.
• From<usize> is removed from Token, the internal field is still public, so
  Token(my_token) can still be used.

Changed

• Various documentation improvements were made around correct usage of Poll
  and registered event sources. It is recommended to reread the documentation of
  at least event::Source and Poll.
• Mio now uses Rust 2018 and rustfmt for all code.
• Event was changed to be a wrapper around the OS event. This means it can be
  significantly larger on some OSs.
• Ready was removed and replaced with various is_* methods on Event. For
  example instead checking for readable readiness using
  Event::ready().is_readable(), you would call Event::is_readable().
• Ready::is_hup was removed in favour of Event::is_read_closed and
  Event::is_write_closed.
• The Iterator implementation of Events was changed to return &Event.
• Evented was renamed to event::Source and now takes mutable reference to
  the source.
• Minimum supported Rust version was increased to 1.39.
• By default Mio now uses a shim implementation. To enable the full
  implementation, that uses the OS, enable the os-oll feature. To enable the
  network types use tcp, udp and/or uds. For more documentation on the
  features see the feature module in the API documentation (requires the
  extra-docs feature).
• The entire Windows implementation was rewritten.
• Various optimisation were made to reduce the number of system calls in
  creating and using sockets, e.g. making use of accept4(2).
• The fmt::Debug implementation of Events is now actually useful as it
  prints all Events.

v0.6.23

Compare Source

Changed

• MSRV: Increased the MSRV from 1.18.0 (Jun 8, 2017) to 1.31.0 (Dec 6,
  2018)
  (tokio-rs/mio@4879e0d).

Fixed

• Work around Linux kernel < 2.6.37 bug on 32-bits making timeouts longer then
  ~30 minutes effectively infinite
  (tokio-rs/mio@e7cba59).
• Update miow and net2 depedencies to get rid of invalid memory layout assumption
  (tokio-rs/mio@13f02ac).
