From ad746f25f268ef0ad3aeddc41bc05287c1d0d006 Mon Sep 17 00:00:00 2001 From: Michael Sloan Date: Sat, 30 Aug 2025 14:13:39 -0600 Subject: [PATCH] zeta: Add zlib to license detection + ignore symbol differences (#37238) See discussion on #36564. Makes the license regexes a less fragile by not matching on symbols, while also excluding cases where a long file ends with a valid license. Also adds Zlib license, a commented out test to check all license-like files discovered in the homedir, and more testcases. Not too happy with the efficiency here, on my quite good computer it takes ~120ms to compile the regex and allocates ~8mb for it. This is just not a great use of regexes, I think something using eager substring matching would be much more efficient - hoping to followup with that. Release Notes: - Edit Prediction: Added Zlib license to open-source licenses eligible for data collection. --- Cargo.lock | 1 + crates/zeta/Cargo.toml | 1 + .../0bsd.txt | 0 .../apache-2.0-ex0.txt} | 0 .../zeta/license_examples/apache-2.0-ex1.txt | 55 +++++ .../apache-2.0-ex2.txt} | 150 ++++++------ .../zeta/license_examples/apache-2.0-ex3.txt | 13 + .../bsd-1-clause.txt | 0 .../bsd-2-clause-ex0.txt} | 0 .../bsd-3-clause-ex0.txt} | 0 .../license_examples/bsd-3-clause-ex1.txt | 27 +++ .../license_examples/bsd-3-clause-ex2.txt | 31 +++ .../license_examples/bsd-3-clause-ex3.txt | 30 +++ .../license_examples/bsd-3-clause-ex4.txt | 27 +++ .../isc.txt | 0 .../mit.txt => license_examples/mit-ex0.txt} | 0 crates/zeta/license_examples/mit-ex1.txt | 26 ++ crates/zeta/license_examples/mit-ex2.txt | 22 ++ crates/zeta/license_examples/mit-ex3.txt | 21 ++ .../upl-1.0.txt | 0 crates/zeta/license_examples/zlib-ex0.txt | 19 ++ crates/zeta/license_regexes/0bsd.regex | 10 + crates/zeta/license_regexes/apache-2.0.regex | 223 +++++++++++++++++ crates/zeta/license_regexes/bsd.regex | 23 ++ crates/zeta/license_regexes/isc.regex | 12 + crates/zeta/license_regexes/mit.regex | 17 ++ crates/zeta/license_regexes/upl-1.0.regex | 32 +++ crates/zeta/license_regexes/zlib.regex | 18 ++ crates/zeta/src/license_detection.rs | 229 +++++++++++++++--- crates/zeta/src/license_detection/0bsd.regex | 12 -
