The case `nbyte == INT_MAX` is valid, so the subtraction (`- 1`) in ```rust const READ_LIMIT: usize = if cfg!(target_vendor = "apple") { libc::c_int::MAX as usize - 1 // <- HERE } else { libc::ssize_t::MAX as usize }; ``` can be removed. I tested that the case `nbyte == INT_MAX` is valid on various versions of macOS, including old one like Mac OS X 10.5. The man page says: - read() and pread() will fail if the parameter nbyte exceeds INT_MAX (link: https://keith.github.io/xcode-man-pages/read.2.html) - write() and pwrite() will fail if the parameter nbyte exceeds INT_MAX (link: https://keith.github.io/xcode-man-pages/write.2.html) Here are links to Darwin's code: - [macOS 15.5] https://github.com/apple-oss-distributions/xnu/blob/e3723e1f17661b24996789d8afc084c0c3303b26/bsd/kern/sys_generic.c#L307 - [Mac OS X 10.2] https://github.com/apple/darwin-xnu/blob/d738f900846ed2d5f685e18bf85ce63b0176f61a/bsd/kern/sys_generic.c#L220 Related PR: rust-lang/rust#38622. 2025-08-16T12:28:31+00:00 Josh Triplett josh@joshtriplett.org 2025-08-10T21:25:43+00:00 urn:sha1:1ae4a0cc3487f28b29f36afe8056535afad21e7b Migrate the standard library from using the external `cfg_if` crate to using the now-built-in `cfg_select` macro. This does not yet eliminate the dependency from `library/std/Cargo.toml`, because while the standard library itself no longer uses `cfg_if`, it also incorporates the `backtrace` crate, which does. Migration assisted by the following vim command (after selecting the full `cfg_if!` invocation): ``` '<,'>s/\(cfg_if::\)\?cfg_if/cfg_select/ | '<,'>s/^\( *\)} else {/\1}\r\1_ => {/c | '<,'>s/^\( *\)} else if #\[cfg(\(.*\))\] /\1}\r\1\2 => /e | '<,'>s/if #\[cfg(\(.*\))\] {/\1 => {/e ``` This is imperfect, but substantially accelerated the process. This prompts for confirmation on the `} else {` since that can also appear inside one of the arms. This also requires manual intervention to handle any multi-line conditions. 2025-07-25T14:22:36+00:00 morinmorin mimomorin@gmail.com 2025-07-25T14:22:36+00:00 urn:sha1:a6f266612a42737ee46b69645244975e75406b60 Darwin's `read`/`write` syscalls emit `EINVAL` only when `nbyte > INT_MAX`.
