From 739e7ebb3d378ece25d64b39baae47c584253498 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Sat, 4 Mar 2023 09:48:17 +0100 Subject: [PATCH] diagnostics: Fix up selftests with $COLUMNS < 42 [PR108973] As mentioned in the PR, GCC's diagnostics self-tests fail if $COLUMNS < 42. Guarding each self-test with if (get_terminal_width () > 41) or similar would be a maintainance nightmare (PR has a patch to do so without reformatting to make it work for $COLUMNS in [30, 41] inclusive, but I'm afraid going down to $COLUMNS 1 would mean marking everything). Furthermore, the self-tests don't really emit stuff to the terminal, but into a buffer, so using get_terminal_width () for it seems inappropriate. The following patch makes sure test_diagnostic_context constructor uses exactly 80 columns wide caret max width, of course some tests override it already if they want to test for behavior in narrower cases. 2023-03-04 Jakub Jelinek PR testsuite/108973 * selftest-diagnostic.cc (test_diagnostic_context::test_diagnostic_context): Set caret_max_width to 80. --- gcc/selftest-diagnostic.cc | 1 + 1 file changed, 1 insertion(+) diff --git a/gcc/selftest-diagnostic.cc b/gcc/selftest-diagnostic.cc index 6ac9f46dd3ce..6d1bd1bd792b 100644 --- a/gcc/selftest-diagnostic.cc +++ b/gcc/selftest-diagnostic.cc @@ -41,6 +41,7 @@ test_diagnostic_context::test_diagnostic_context () show_column = true; start_span = start_span_cb; min_margin_width = 6; + caret_max_width = 80; } test_diagnostic_context::~test_diagnostic_context () -- 2.47.2
