Previously, when `file` is empty (literally empty, as in, zero byte), `rg -f file` and `rg -vf file` would behave identically. This is odd and also doesn't match how GNU grep behaves. It's also not logically correct. An empty file means _zero_ patterns which is an empty set. An empty set matches nothing. Inverting the empty set should result in matching everything. This was because of an errant optimization that lets ripgrep quit early if it can statically detect that no matches are possible. Moreover, there was *also* a bug in how we constructed the PCRE2 pattern when there are zero patterns. PCRE2 doesn't have a concept of sets of patterns (unlike the `regex` crate), so we need to fake it with an empty character class. Fixes #1332, Fixes #3001, Closes #3041 |
