os: support overlapped IO with NewFile

2025-04-04T21:00:21Z

The runtime/poll package has just gained support for overlapped IO, see CL 660595 and CL 661955. The only remaining piece was making it visible to user code via os.NewFile. Some of the poll.FD.Init responsibility has been moved to os.NewFile to avoid unnecessary syscalls for the common case of using os.Open, os.Create, os.OpenFile, and os.Pipe, where we know that the file is not opened for overlapped IO. Some internal/poll tests have been moved to the os package to exercise public APIs rather than internal ones. The os.NewFile function definition has been moved into an OS-agnostic file to avoid having duplicated documentation and ensure that the caller is aware of its behavior across all platforms. Closes #19098.

internal/syscall/windows: use unsafe.Pointer instead of uintptr

2025-04-04T17:40:19Z

Some functions accept a uintptr when they should accept an unsafe.Pointer, else the compiler won't know that the pointer should be kept alive across the call, potentially causing undefined behavior.

os: avoid symlink races in RemoveAll on Windows

2025-03-31T22:36:10Z

Make the openat-using version of RemoveAll use the appropriate Windows equivalent, via new portable (but internal) functions added for os.Root. We could reimplement everything in terms of os.Root, but this is a bit simpler and keeps the existing code structure.
