The Rust runtime ignores SIGPIPE, but for proper pipeline behavior and compatibility with GNU install, we need to respect the parent's signal disposition. This ensures install behaves correctly in pipelines, exiting with error on broken pipes unless the parent ignored SIGPIPE. --- src/uu/install/src/install.rs | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) diff --git a/src/uu/install/src/install.rs b/src/uu/install/src/install.rs index 3d9b937c469..7d4ef6cce91 100644 --- a/src/uu/install/src/install.rs +++ b/src/uu/install/src/install.rs @@ -37,7 +37,7 @@ use uucore::selinux::{ set_selinux_security_context, }; #[cfg(unix)] -use uucore::signals::enable_pipe_errors; +use uucore::signals; use uucore::translate; use uucore::{format_usage, os_str_from_bytes, show, show_error, show_if_err}; @@ -51,6 +51,10 @@ use std::os::unix::fs::FileTypeExt; const DEFAULT_MODE: u32 = 0o755; const DEFAULT_STRIP_PROGRAM: &str = "strip"; +// Initialize SIGPIPE state capture at process startup (Unix only) +#[cfg(unix)] +uucore::init_sigpipe_capture!(); + #[allow(dead_code)] pub struct Behavior { main_function: MainFunction, @@ -197,8 +201,15 @@ fn is_path_separator_byte(byte: u8) -> bool { /// #[uucore::main] pub fn uumain(args: impl uucore::Args) -> UResult<()> { + // Restore SIGPIPE to default if it wasn't explicitly ignored by parent. + // The Rust runtime ignores SIGPIPE, but we need to respect the parent's + // signal disposition for proper pipeline behavior (GNU compatibility). #[cfg(unix)] - enable_pipe_errors()?; + if !signals::sigpipe_was_ignored() { + // Ignore the return value: if setting signal handler fails, we continue anyway. + // The worst case is we don't get proper SIGPIPE behavior, but install will still work. + let _ = signals::enable_pipe_errors(); + } let matches = uucore::clap_localization::handle_clap_result(uu_app(), args)?;
