--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:739e7ebb3d378ece25d64b39baae47c584253498 commit r13-6472-g739e7ebb3d378ece25d64b39baae47c584253498 Author: Jakub Jelinek <ja...@redhat.com> Date: Sat Mar 4 09:48:17 2023 +0100 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 <ja...@redhat.com> PR testsuite/108973 * selftest-diagnostic.cc (test_diagnostic_context::test_diagnostic_context): Set caret_max_width to 80.
