From cac7e42b5278ad46214c741f01e537dff1fa9372 Mon Sep 17 00:00:00 2001 From: Ulrich Weigand Date: Wed, 10 May 2023 20:22:17 +0200 Subject: [PATCH] Fix backtrace normalization in ice-bug-report-url.rs This test case currently fails on s390x, and probably other platforms where the last line of a backtrace does not contain and " at " specification. The problem with the existing normalization lines // normalize-stderr-test "\s*\d{1,}: .*\n" -> "" // normalize-stderr-test "\s at .*\n" -> "" is that \s matches all whitespace, including newlines, so the first (but not second) of these regexes may merge multiple lines. Thus the output differs depending on which of these matches on the last line of a backtrace. As the whitespace used in backtraces is just normal space characters, change both regexes to just match at least one space character instead: // normalize-stderr-test " +\d{1,}: .*\n" -> "" // normalize-stderr-test " + at .*\n" -> "" --- tests/rustdoc-ui/ice-bug-report-url.rs | 4 ++-- tests/rustdoc-ui/ice-bug-report-url.stderr | 1 + 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/tests/rustdoc-ui/ice-bug-report-url.rs b/tests/rustdoc-ui/ice-bug-report-url.rs index cc066447d313b..8ede91cf8f4f4 100644 --- a/tests/rustdoc-ui/ice-bug-report-url.rs +++ b/tests/rustdoc-ui/ice-bug-report-url.rs @@ -6,8 +6,8 @@ // normalize-stderr-test "note: compiler flags.*\n\n" -> "" // normalize-stderr-test "note: rustc.*running on.*" -> "note: rustc {version} running on {platform}" // normalize-stderr-test "thread.*panicked at .*, compiler.*" -> "thread panicked at 'aborting due to `-Z treat-err-as-bug`'" -// normalize-stderr-test "\s*\d{1,}: .*\n" -> "" -// normalize-stderr-test "\s at .*\n" -> "" +// normalize-stderr-test " +\d{1,}: .*\n" -> "" +// normalize-stderr-test " + at .*\n" -> "" // normalize-stderr-test ".*note: Some details are omitted.*\n" -> "" fn wrong() diff --git a/tests/rustdoc-ui/ice-bug-report-url.stderr b/tests/rustdoc-ui/ice-bug-report-url.stderr index cfb73a9b9193f..98c08b9a8944b 100644 --- a/tests/rustdoc-ui/ice-bug-report-url.stderr +++ b/tests/rustdoc-ui/ice-bug-report-url.stderr @@ -6,6 +6,7 @@ LL | fn wrong() thread panicked at 'aborting due to `-Z treat-err-as-bug`' stack backtrace: + error: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-rustdoc&template=ice.md
