• Consistently close transports if create_server/create_connection/etc timeout or cancelled. (by @1st1 in ac90d8bd and 77ee4f96)

New Features

Bug Fixes

• Upgrade to Cython 0.28.2. (by @1st1 in 98bdb553 for #122)

• Update libuv from v1.17.0 to v1.20.3. (by @1st1 in 572524a6)

• Make sure UDP handles are cleaned-up properly. (by @1st1 in 13f63e00)

• Fix subprocess.close() to let its processes die gracefully. (by @1st1 in a78e4d27 and a455af3d for #128)

• Fix sock_connect() to resolve addresses for correct socket family. (by @1st1 in ce2bd4fb for #139)

• Fix a race condition in SSL handshake. (by @1st1 in 447e124f)

• Stop using malloc for uv_request* handlers.

• Fix loop.add_reader(), loop.add_writer(), loop.remove_reader(), and loop.remove_writer() to better track socket objects.

• Fix loop.sock_recv(), loop.sock_sendall(), loop.sock_recv_into(), and loop.sock_connect() to correctly handle Task.cancel().

• Better handle immediate cancellation of loop.create_connection().

• Make unit tests stricter: ensure loop.call_exception_handler() does not get called, unless it's expected.

TCP & UDP Transports

• transport.get_extra_info('socket') now returns a socket-like object. It supports socket methods like setsockopts(), but prohibits send(), recv(), close() and any other calls that can interfere with the transport that ultimately owns this file descriptor.

• TCP_NODELAY is used by default for all TCP connections.

• Make Transport.resume_reading() and pause_reading() idempotent. This will match asyncio in Python 3.7. Issue #93.

• loop.create_server() keeps a strong reference to the Server object it returns until its closed. Fixes #81.

• Fix loop.connect_accepted_socket() to return correct SSL transport.

• The UDP transport layer was rewritten from scratch. Now it uses uv_poll_* libuv APIs, instead of high-level uv_udp_* ones. This could mean a slight performance regression, and will be reverted when we port uvloop to Windows. For now this is the only viable option to make uvloop fully compatible with asyncio. When libuv gets an API to connect UDP sockets, uv_udp_connect(), we'll be able to switch to a better UDP implementation. Issue #109.

• UDPTransport.sendto(data, addr) will raise an exception if addr requires a name resolution. Issue #91.

Low-level sockets

• loop.add_reader() and loop.add_writer() accept file-like objects. Issue #97.

• loop.sock_connect() supports 4 element address tuples for IPv6 sockets. Issue #99.

• Protect sockets from closing while they are in use by loop.sock_*() methods. Close all reader/writer sockets the loop owns when it closes. Issue #100.

Other event loop APIs

• loop.run_until_complete() cleans up done callbacks in all situations. By @jimmylai. See also Python issue: https://bugs.python.org/issue30423.

• New uv_loop_fork() libuv API is used in loop.subprocess_shell() and loop.subprocess_exec() making them more stable. Issue #39.

• loop.call_later() accepts infinite time float('inf'). Issue #102.

• loop.subprocess_exec() accepts pathlib.Path objects for its cwd parameter. Issue #90.

• Support pathlib.Path objects in loop.create_unix_connection() and loop.create_unix_server().

• Try removing existing stale Unix socket paths in loop.create_unix_server().

• ascii encoding is tried before encoding with idna. Issue #95.

• Fix slow_callback_duration repr in warnings for callback handles and Tasks. Issue #103.

Python 3.7

Some APIs that will be available in Python 3.7 in vanilla asyncio, but can be used with uvloop today.

• Implement .cancelled() method for callback and timer handles.

• Add Transport.is_reading().

• Implement loop.sock_recv_into().

• Python 3.7.0a1 is now supported. Issue #110.

Miscellaneous

• Drop custom uvloop Future and Task implementations. This means that there will be a tiny performance regression for Python 3.5 deploys.

• Limit stack traces in debug mode to make it faster.

• signal.siginterrupt is now used by signals machinery to let system calls to be repeated by default, instead of raising an EINTR.

Build

• libuv in uvloop has been upgraded from v1.11.0 to v1.17.0. Aside from bug fixes and performance improvements, libuv survives fork.

• LIBUV_CONFIGURE_HOST environment variable can be used to cross-compile uvloop/libuv. By @cmcqueen, for issue #104.

• Cyhton was upgraded from 0.25.2 to 0.27.3.

• uvloop binary is linked with pthread. By @frederikaalund, for issue #87.
