Clicking on the top entry (iphone) takes me to 404:
https://github.com/roc-lang/roc/blob/e3f3714d7bf9aec537a137f2934c1966b30f8a56/src/fuzz-parse.zig
Rick Hull (Jan 25 2026 at 13:42):Looks like a Luke branch, maybe transient. Or bad path to fuzz-parse.zig
Rick Hull (Jan 25 2026 at 13:46):Also: the bottom of src/README.md says Overview, then broken link: https://camo.githubusercontent.com/ddd54d7d0d304761ee604e07b0efc6442a83b6a90f8ffaad64acea7a1277e69c/68747470733a2f2f616e746f6e2d342e6769746875622e696f2f726f632d636f6d70696c65722d7669732f7a69675f646570656e64656e63795f67726170682e77656270
Rick Hull (Jan 25 2026 at 13:47):I found https://github.com/roc-lang/roc/tree/main/test/fuzzing
Rick Hull (Jan 25 2026 at 13:48):Sorry, im on iphone w one finger typing
Rick Hull (Jan 25 2026 at 13:52):I don't see the nature of the failure anywhere. I can click the coverage field, but iphone thinks phone number. I can't click e.g. "12 crashes"
Rick Hull (Jan 25 2026 at 13:53):Is the path to the fuzz script set in GHA?
Rick Hull (Jan 25 2026 at 20:32):Luke showed on the meeting to copy/paste the fuzz cmd and run locally. I don't have a terminal, but Id like to improve the fuzzing web ui. Maybe show the failure like traditional CI, but maybe this is less sensible for fuzzing results
Brendan Hansknecht (Jan 28 2026 at 04:56):That sounds like a good idea
Brendan Hansknecht (Jan 28 2026 at 04:56):We should be able to capture the verbose fuzz failure output and report it
Rick Hull (Jan 28 2026 at 05:01):I see a few action items:
Now that I have a terminal and keyboard available, I can start with manually running the fuzz commands and pick up more context that way. but happy to try to run with any of the 3 above as well
Brendan Hansknecht (Jan 30 2026 at 04:26):The code is fuzzers, CI jobs, and some zig code to generate the website. Pretty simple and fast to start up on bar fuzzing dependencies
Brendan Hansknecht (Jan 30 2026 at 04:27):You can work on the website using the checked in fuzzing data, but might need to expand it with more data for some of this work.
Luke Boswell (Jan 30 2026 at 04:28):Earlier today I fixed the snapshot tool for generating a seed corpus using our snapshots. It did support the REPL type snapshots.
