From c7a28d579b8209337fe959e2384d3884878d887c Mon Sep 17 00:00:00 2001 From: jyn Date: Tue, 24 Dec 2024 20:40:44 -0500 Subject: [PATCH] Default to short backtraces for dev builds of rustc itself A dev build almost certainly means that whoever's built the compiler has the opportunity to rerun it to collect a more complete trace. So we don't need to default to a complete trace; we should hide irrelevant details by default. --- compiler/rustc_driver_impl/src/lib.rs | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/compiler/rustc_driver_impl/src/lib.rs b/compiler/rustc_driver_impl/src/lib.rs index 3dc39fc131af4..b13cc4d0b066d 100644 --- a/compiler/rustc_driver_impl/src/lib.rs +++ b/compiler/rustc_driver_impl/src/lib.rs @@ -1388,7 +1388,11 @@ pub fn install_ice_hook( // opt in to less-verbose backtraces by manually setting "RUST_BACKTRACE" // (e.g. `RUST_BACKTRACE=1`) if env::var_os("RUST_BACKTRACE").is_none() { - panic::set_backtrace_style(panic::BacktraceStyle::Full); + if env!("CFG_RELEASE_CHANNEL") == "dev" { + panic::set_backtrace_style(panic::BacktraceStyle::Short); + } else { + panic::set_backtrace_style(panic::BacktraceStyle::Full); + } } let using_internal_features = Arc::new(std::sync::atomic::AtomicBool::default());
