This is beta-level support for fuzzing the Tectonic engine using cargo-fuzz. At the moment, the fuzzing does not work very well because it exposes memory leaks in the Tectonic engine; this is desirable in and of itself, but the exposed leaks have proven to be tricky to fix. (Patches most welcome, of course! The limiting factor here is definitely developer bandwidth.)
See the script ./run-fuzzer.sh for an example of how to, well, run the
fuzzer. Note that this script sets a rustup directory override to build
Tectonic using the nightly compilers, since nightly is currently required by
the fuzzer.
To tell the fuzzer to ignore memory leaks, run a command like the following from the toplevel directory of the Tectonic repository:
cargo +nightly fuzz run compile fuzz/corpus fuzz/seeds -- -detect_leaks=0
