This branch deletes std.fs.File in favor of std.Io.File and std.fs.Dir in favor of std.Io.Dir, as well as moving almost all std.fs API into std.Io.Dir.

The main purpose is to integrate file system I/O with the std.Io interface, which is a major part of #30150.

I also took advantage of the breakage to rename a number of file system APIs for consistency.

Upgrade Guide

Although it's a lot of breaking changes, unlike "writergate", this changeset is expected to be generally easy for Zig programmers to manage, because it does not require much critical thinking. For example, typical upgrade path will look something like this:

-file.close();
+file.close(io);

Although your upgrade diff might be large, it will be quite simple to understand what needs to be done.

Added:

• std.Io.Dir.hardLink
• std.Io.Dir.Reader
• std.Io.Dir.setFilePermissions
• std.Io.Dir.setFileOwner
• std.Io.File.NLink

Removed with no replacement:

• std.fs.realpathZ

std.Progress Note

After updating your application that uses std.Progress:

-        const root_progress_node = std.Progress.start(.{
+        const root_progress_node = std.Progress.start(io, .{

Make sure you have defer root_progress_node.end(); there. Before, if control flow got to the end of main(), start code would exit all threads, including the std.Progress thread. Now, it is not a thread but a task, and you likely have defer threaded.deinit(); above there, which will wait until all tasks are finished. If your application hangs, double check that your std.Progress.start have a matching node.end().

Followup Tasks

• remove error.UnsupportedClock from some error sets
• #30150
• https://github.com/ziglang/zig/issues/24510

std.fs.File.getEndPos -> std.Io.File.getLength

The getLength function doesn't exist in std.Io.File, however, I am able the length function for this functionality.

Is there a typo here or should I create a PR renaming length to getLength ?

Just to have it documented here (for release notes): This breaks stack walking on freestanding by making things like captureStackTrace implicitly depend on std.Options.debug_io.

There, we, on freestanding, need to set root.std_options_debug_io to some std.Io interface that:

• needs to work when we have our debug.SelfInfo.can_unwind == true (iirc) and our unwind_frame function actually uses any function from the std.Io interface
• does not need to work when we either use stack unwinding (called the "unsafe" option) or don't use the std.Io interface while unwinding (if it stays so that captureStackTrace does nothing with the io parameter and only gives it to unwindFrame).

Option 2 ("does not need to work") could be #30691.
