Drawing sheet 014: 212 regexes. Zero that can hang your server.

General notes

  1. 01A pattern with nested or unbounded repetition can take seconds, then minutes, on one crafted input. Denial of service with no traffic spike.
  2. 02Every pattern is bounded and re-checked by a static scanner on every commit. A new unsafe pattern fails the build.
  3. 03Production-ready is a number you can re-run, not an adjective in a README.
212 /0
Patterns in the engine / patterns that can backtrack catastrophically.
