runtime(syntax-tests): Filter out non-Latin-1 characters for syntax tests (#14767) Commit: https://github.com/vim/vim/commit/2f5ff738278160a3b62c565d586eab8a9e39bc33 Author: Aliaksei Budavei <32549825+zzzyxwvut@users.noreply.github.com> Date: Mon May 13 22:06:05 2024 +0300 runtime(syntax-tests): Filter out non-Latin-1 characters for syntax tests (https://github.com/vim/vim/issues/14767) Syntax tests are run with the LC_ALL=C environment variable passed to "make". Occasionally, there are CI failures for such test files containing non-Latin-1 characters with error messages pointing to multi-byte characters: https://github.com/vim/vim/actions/runs/8824925004/job/24228298023#step:10:16370 , https://github.com/vim/vim/actions/runs/8840856619/job/24276935260#step:10:16347 , https://github.com/vim/vim/actions/runs/8854043458/job/24316210645#step:10:16362 , https://github.com/vim/vim/actions/runs/8856501136/job/24322848765#step:10:16354 , https://github.com/vim/vim/actions/runs/9038417238/job/24839482152#step:11:16980 . But since the very same unchanged tests pass at other times: https://github.com/vim/vim/actions/runs/8827593571/job/24235935458#step:10:16353 , https://github.com/vim/vim/actions/runs/9065214647/job/24905321661#step:11:17002 ; these failures are unrelated to the nature of syntax tests and should be considered false positives. As a temporary workaround, all bytes of known non-Latin-1 characters can be replaced in memory with an arbitrary ASCII byte (?) by applying a filter > " To ignore part of the dump, provide a "dumps/{filename}.vim" file with > " Vim commands to be applied to both the reference and the current dump, so > " that parts that are irrelevant are not used for the comparison. The result > " is NOT written, thus "term_dumpdiff()" shows the difference anyway. before lines are compared between files.
