almost every regex engine today descends from one of two approaches: Thompson’s NFA construction (1968) or backtracking (1994). Thompson-style engines (grep, RE2, Rust’s regex) give you linear-time guarantees but only support the “standard” fragment - | and *. backtracking engines (the rest, 95% chance the one you’re using) give you a mix of advanced features like backreferences, lookarounds.., but are unreliable, and can blow up to exponential time on adversarial inputs, which is a real security concern known as ReDoS. to be more precise, this exponential behavior is not the only problem with backtracking engines - they also handle the OR (|) operator much slower, but let’s try to start with the big picture.。业内人士推荐PDF资料作为进阶阅读

“I talk to the airlines, and they realize there is a looming threat,” Paul Williams told me. “But it’s quite distant for them. They see it as decades in the future. The people really taking notice are the designers. The airplanes they’re designing now will still be flying in 2050, so they can’t wait. And here is a bit of a shocking thing: the design and certification standards for air worthiness are based on turbulence measurements from the nineteen-sixties. It’s reasonable to ask, Are those standards still fit for the purpose? Will they still be fit for the purpose in 2050?”
