1.0 release planning

[sunfishcode]

Here's a planning issue for a 1.0 release, similar to the one for the 0.38 release. Hopefully we won't need a semver bump for a good long while, but when we do, here's the list of changes we can make:

• Remove the deprecated mount functions in the fs module (details)
• Make the underlying type of rustix::fs::Access consistent between linux_raw and libc backends (Port 1.0-staging to main #1152)
• Rename mount_recursive_bind to mount_bind_recursive? Factor out a new top-level mount module. #763 (comment) (Rename mount_recursive_bind to mount_bind_recursive. #1273)
• Change SeekFrom::Hole and SeekFrom::Data's field from i64 to u64. (Make the offsets for SeekFrom's Hole and Data unsigned. #1266)
• rename Shutdown::ReadWrite to Shutdown::Both to align with std (Rename Shutdown::ReadWrite to Shutdown::Both. #1264)
• remove the features = ["extra_traits"] from the libc dependency (Remove the "libc-extra-traits" feature. #1168)
• move (or perhaps alias?) sched_yield and other sched_* functions from process to thread, since they apply to threads rather than processes on Linux etc. (Move sched_* and membarrier_* into rustix::thread. #1265)
• stx_mtime and similar members of Statx should be i64, because Unix timestamps can be negative.
• futex's first argument should be Atomic
• Remove get_ from sockopt getters, following Rust convention. Consider removing get_ in other things too. (Rename sockopts getters to remove the "get_". #1269)
• The udata argument to rustix::event::kqueue::Event::new should be a pointer instead of an isize in order to better preserve provenance. (Make APIs preserve strict provenance. #1270)
• The stx_attributes_mask field of Statx with flags like libc::STATX_ATTR_MOUNT_ROOT should ideally be a bitflags, which requires making Statx a custom type (which should match layout with libc::statx). (Reorganize Stat, Statx, and SockaddrStorage #1282)
• Rename get_* functions (eg. sockopts) to remove the get_ prefix, which is more idiomatic Rust?
• Rename MountPropagationFlags::SLAVE (Rename a flag in MountPropagationFlags. #1169)
• Rename some of WaitidOptions, WaitidStatus, and/or WaitId to make the capitalization of Id consistent (Rename Waidid* to WaidId*, for consistency with WaitId. #1267)
• Remove the inotify_ prefixes from things in the fs::inotify module.
• Remove the shm_ and Shm prefixes from things in the shm module.
• Figure out a way to do a recv into an uninitialized buffer with the TRUNC flag set (see Fix recv_uninit to handle the TRUNC flag. #1159) (Report the number of received bytes in recv_uninit and recvfrom_uninit. #1278)
• remove rustix::procfs and publish rustix-linux-procfs as the replacement (Remove procfs. #1275)
• remove linux-raw-sys from the public API (Port 1.0-staging to main #1152) (Remove most linux-raw-sys types from the public API #1277) (Reorganize Stat, Statx, and SockaddrStorage #1282)
• change io_uring_register_files_skip from a const fn to a constant. (Replace the io_uring_register_files_skip function with a constant. #1268)

Deferring for now:

• move rustix::thread sleep functions into a new rustix::sleep module, because they're usable from single-threaded programs too
• Move Dir into its own crate, and have rustix export getdents directly?
• Split open and openat into separate functions for "create" which needs a mode vs. "open existing" which doesn't need a mode?
• Make RecvAncillaryBuffer::drain always remove all messages, even if the iterator isn't exhausted. With that, we can remove the read_and_length in AncillaryDrain.
• Replace rustix::cstr! with something like rustix::nativestr! so that users don't hard code "native strings are C strings" in their code?
• rename Arg::as_str to avoid "a method with this name may be added to the standard library in the future" warnings
• rustix::process::waitpid has no way to wait for specific process groups (Pid now requires non-negative values). waitpgid has been added as a temporary workaround.
• remove libc from the public API (Port 1.0-staging to main #1152) (Remove most linux-raw-sys types from the public API #1277)

Don't do these:

• set_ip_add_membership/get_ip_add_membership should take address and ifindex arguments and *_with_ifindex should be removed.
• Rename ClockId::Uptime on FreeBSD to Boottime, since it's an alias

I've now published rustix 1.0.0-prerelease.1. Please test out the prerelease, and please comment on if there are any problems or if there are any changes we should consider before releasing 1.0.

I've documented all the API changes I'm aware of here; please let me know if anything there is unclear or if there's something not covered.

Just did the upgrade in Ringboard and it went pretty smoothly: SUPERCILEX/clipboard-history@28109d2

[Stebalien]

I've tested on both tempfile and xattr and I've seen no real issues.

[sunfishcode]

Thanks for the reports! I've now done more testing too, and fixed a few issues that came up. I think everything is ready for a 1.0.0 release. I'm thinking of doing the release two days from now, unless any problems surface.

Rustix 1.0.0 is now released! Thanks to everyone who helped submit patches, bug reports, code reviews, and testing!
