https://docs.rs/rustc-artifacts/0.2.0/rustc_artifacts/fn.master_commits.html provides access to bors commit data that doesn't depend on the GitHub API. It provides less information than we might want today, but I would be willing to expand...

Only write regressed crates as raw logs

1

This avoids a whole bunch of time writing logs for every crate out there. We could optimize the writing itself (e.g., doing it in parallel would likely be a huge...

Git dependencies can be inconsistent between compared runs

2

e.g., https://crater-reports.s3.amazonaws.com/beta-1.46-1/1.45.2/gh/jockbert.jockbert_ants_bot/log.txt vs https://crater-reports.s3.amazonaws.com/beta-1.46-1/beta-2020-07-24/gh/jockbert.jockbert_ants_bot/log.txt shows: ``` https://github.com/jockbert/ants_ai_challenge_api#028d07e1 https://github.com/jockbert/ants_ai_challenge_api#1924a992 ``` These two versions should be the same if we're to accurately reproduce ourselves.

It would be nice for URL stability and potentially URL rewriting and/or some other dynamic generation if we served logs from crater.rust-lang.org instead of the S3 bucket; this can internally...

From the original issue (https://github.com/rust-lang/rust/issues/33638), by eddyb: We could be missing out on huge bugs just because they aren't obvious regressions. And on the other hand, timeouts just fudge the...

Small error when parsing long float value

12

JavaScript's JSON.parse doesn't lose precision from my tests. Test case below: ``` rust #[test] fn large_precision() { assert_eq!(parse("0.004750000000000001").unwrap().as_f64().unwrap(), 0.004750000000000001); } ```

Bump to 1.65.0

regression: "self" in writeln! drops too early

13

In https://crater-reports.s3.amazonaws.com/beta-1.63-2/beta-2022-07-16/reg/cabot-0.7.1/log.txt, it looks like the `stderr()` temporary isn't living long enough with the changes after https://github.com/rust-lang/rust/pull/96455. However, I've not actually bisected or investigated thoroughly to confirm this -- it...

Unions require Copy fields, but ignore regions in the check

```rust union Bar, } struct Foo { fn clone(&self) -> Self { *self } } ``` https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=4cc269cb234497a007039d6ddbc41943 It seems to me that the above code should probably be rejected, since...
