* `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.
