Ah, the dangers of I think it makes more sense to just filter out deprecated lint groups, they are not what people should use so we shouldn't suggest them. |
The no_lint_suggestion routine passes a vector of lint group names to find_best_match_for_name. That routine depends on the sort order of its input vector, which matters in case multiple inputs are at the same Levenshtein distance to the target name. However, no_lint_suggestion currently just passes lint_groups.keys() as input vector - this is sorted in hash value order, which is not guaranteed to be stable, and in fact differs between big- and little-endian host platforms, causing test failures on s390x. To fix this, always sort the lint groups before using their names as input to find_best_match_for_name. In addition, deprecated lint groups should never be suggested, so filter those out. Fixes rust-lang#105379

In doing so, prefer non- deprecated lint group names over deprecated ones, and then use alphabetical order. Fixes rust-lang#105379
