From df29d0a111da3a555d8f0751722ca70fe0c5ffc0 Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Tue, 17 Nov 2020 14:58:24 -0500 Subject: [PATCH] glcpp: Handle bison-3.6 error message changes In bison's commit 72c9fa4510eb (skeletons: use "end of file" instead of "$end") in bison-3.6, '$end' was changed to 'end of file' in error messages. Since our glcpp test cases contain the expected output text, they rely on the particular messages printed by bison. The test case 084-unbalanced-parentheses fails when Mesa is built with bison-3.6 due to this change. To allow the test to pass on all supported versions of bison, we: 1. Change '$end' -> 'end of file' in the .expected file, and 2. Normalize the error generated by the test case with the same replacement Cc: mesa-stable Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3181 Reviewed-by: Pierre-Eric Pelloux-Prayer Part-of: --- .../glsl/glcpp/tests/084-unbalanced-parentheses.c.expected | 2 +- src/compiler/glsl/glcpp/tests/glcpp_test.py | 4 ++++ 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/src/compiler/glsl/glcpp/tests/084-unbalanced-parentheses.c.expected b/src/compiler/glsl/glcpp/tests/084-unbalanced-parentheses.c.expected index af49a37369d..6af8033b0a3 100644 --- a/src/compiler/glsl/glcpp/tests/084-unbalanced-parentheses.c.expected +++ b/src/compiler/glsl/glcpp/tests/084-unbalanced-parentheses.c.expected @@ -1,2 +1,2 @@ -0:2(8): preprocessor error: syntax error, unexpected $end +0:2(8): preprocessor error: syntax error, unexpected end of file diff --git a/src/compiler/glsl/glcpp/tests/glcpp_test.py b/src/compiler/glsl/glcpp/tests/glcpp_test.py index 457bf823612..d3fdc6b27d7 100644 --- a/src/compiler/glsl/glcpp/tests/glcpp_test.py +++ b/src/compiler/glsl/glcpp/tests/glcpp_test.py @@ -83,6 +83,10 @@ def test_output(glcpp, filename, expfile, nl_format='\n'): with open(expfile, 'r') as f: expected = f.read() + # Bison 3.6 changed '$end' to 'end of file' in its error messages + # See: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3181 + actual = actual.replace('$end', 'end of file') + if actual == expected: return (True, []) return (False, difflib.unified_diff(actual.splitlines(), expected.splitlines()))
