Fuzzing for Crystal programming language

crystal fuzz_parser/main.cr

• Fuzzes Crystal's parser and code stringifier.

• Uses existing parser specs as samples.

• Writes errors into a local SQLite database.

  • Possible sets of fields (others NULL):

    original_src	parsed_src	reparsed_src	exception	outcome of Crystal compiler's actions
    ✔				crashed during initial parsing
    ✔			✔	threw an exception during initial parsing
    ✔	✔		✔	parsed a sample and stringified it but raised when parsing that again
    ✔	✔	✔		parsed and stringified a sample, but parsing and stringifying that again produced a different result

  • sqlitebrowser recommended for viewing.

• Requires: crystal, radamsa, libsqlite3.
