Subject: [PATCH] diagnostics: Fix up selftests with $COLUMNS < 42 [PR108973]
Date: Fri, 3 Mar 2023 10:35:54 +0100	[thread overview]
Message-ID: <ZAG/euZxYFFWr5N9@tucnak> (raw)

Hi!

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 at least 80 columns wide caret max width, of course
some tests override it already if they want to test for behavior in narrower
cases.

Bootstrapped/regtested on x86_64-linux and i686-linux, plus tested
on self-tests with $COLUMNS down to 1, ok for trunk?
