Socket I/O methods such as read, readv, write, writev, send, recv,
sendmsg, recvmsg have been generalized to read(buf, flags), write(buf,
flags), readVectorized(vectors, flags), and writeVectorized(vectors,
flags). There is still some work left to be done abstracting both
readVectorized and writeVectorized properly across platforms, which is
work to be done in a future PR.
Support for setting the linger timeout of a socket, querying the remote
address of a socket, setting whether or not keep-alive messages are to
be sent through a connection-oriented socket periodically depending on
host operating system settings has been added.
`std.io.Reader` and `std.io.Writer` wrappers around `Socket` has been
implemented, which wrap around Socket.read(buf, flags) and
Socket.write(buf, flags). Both wrappers may be provided flags which are
passed to Socket.read / Socket.write accordingly.
Cross-platform support for `getpeername()` has been implemented.
Windows support for the new `std.x.os.Socket` has been implemented. To
accomplish this, a full refactor of `std.os.windows.ws2_32` has been
done to supply any missing definitions and constants based on
auto-generated Windows syscall bindings by @marler8997.
`std.x.net.TCP.Listener.setQuickACK` has been moved to
`std.x.net.TCP.Client.setQuickACK`.
Windows support for resolving the scope ID of an interface name
specified in an IPv6 address has been provided.
`sockaddr_storage` definitions have been provided for Windows, Linux,
and Darwin. `sockaddr_storage` is used to allocate space before any
socket addresses are queried via. calls such as accept(), getsockname(),
and getpeername().
Zig-friendly wrappers for GetQueuedCompletionStatusEx(), getpeername(),
SetConsoleCtrlHandler(), SetFileCompletionNotificationModes() syscalls
on Windows have been provided.
Socket.setOption() was provided to set the value of a socket option in
place of os.setsockopt. Socket.getOption() will be provided in a future
PR.
There is still further work to be done regarding querying socket option
values on Windows, which is to be done in a subsequent PR.
* `zig test` gainst `--test-evented-io` parameter and gains the ability
to seamlessly run async tests.
* `std.ChildProcess` opens its child process pipe with O_NONBLOCK when
using evented I/O
* `std.io.getStdErr()` gives a File that is blocking even in evented
I/O mode.
* Delete `std.event.fs`. The functionality is now merged into `std.fs`
and async file system access (using a dedicated thread) is
automatically handled.
* `std.fs.File` can be configured to specify whether its handle is
expected to block, and whether that is OK to block even when in
async I/O mode. This makes async I/O work correctly for e.g. the
file system as well as network.
* `std.fs.File` has some deprecated functions removed.
* Missing readv,writev,pread,pwrite,preadv,pwritev functions are added
to `std.os` and `std.fs.File`. They are all integrated with async
I/O.
* `std.fs.Watch` is still bit rotted and needs to be audited in light
of the new async/await syntax.
* `std.io.OutStream` integrates with async I/O
* linked list nodes in the std lib have default `null` values for
`prev` and `next`.
* Windows async I/O integration is enabled for reading/writing file
handles.
* Added `std.os.mode_t`. Integer sizes need to be audited.
* Fixed#4403 which was causing compiler to crash.
This is working towards:
./zig test ../test/stage1/behavior.zig --test-evented-io
Which does not successfully build yet. I'd like to enable behavioral
tests and std lib tests with --test-evented-io in the test matrix in the
future, to prevent regressions.
* Delete `std.net.TmpWinAddr`. I don't think that was ever meant to
be a real thing.
* Delete `std.net.OsAddress`. This abstraction was not helpful.
* Rename `std.net.Address` to `std.net.IpAddress`. It is now an extern
union of IPv4 and IPv6 addresses.
* Move `std.net.parseIp4` and `std.net.parseIp6` to the
`std.net.IpAddress` namespace. They now return `IpAddress` instead of
`u32` and `std.net.Ip6Addr`, which is deleted.
* Add `std.net.IpAddress.parse` which accepts a port and parses either
an IPv4 or IPv6 address.
* Add `std.net.IpAddress.parseExpectingFamily` which additionally
accepts a `family` parameter.
* `std.net.IpAddress.initIp4` and `std.net.IpAddress.initIp6` are
improved to directly take the address fields instead of a weird
in-between type.
* `std.net.IpAddress.port` is renamed to `std.net.IpAddress.getPort`.
* Added `std.net.IpAddress.setPort`.
* `os.sockaddr` struct on all targets is improved to match the
corresponding system struct. Previously I had made it a union of
sockaddr_in, sockaddr_in6, and sockaddr_un. The new abstraction for
this is now `std.net.IpAddress`.
* `os.sockaddr` and related bits are added for Windows.
* `os.sockaddr` and related bits now have the `zero` fields default
to zero initialization, and `len` fields default to the correct size.
This is enough to abstract the differences across targets, and so
no more switch on the target OS is needed in `std.net.IpAddress`.
* Add the missing `os.sockaddr_un` on FreeBSD and NetBSD.
* `std.net.IpAddress.initPosix` now takes a pointer to `os.sockaddr`.
