Change Details

PHP8 will switch to PCRE2, which has stricter validation, which could be an issue given that we run user-provided regexps. If there's no tool to detect these in advance, I guess it's fine if we wait for the PHP8 upgrade, check logstash and reach out to the community.

PHP8 will switch off the PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL option (see T248075), which could be an issue given that we run user-provided regexps. If there's no tool to detect these in advance, I guess it's fine if we wait for the PHP8 upgrade, check logstash and reach out to the community.
