yaml-rust appears unmaintained...

Stumbled onto https://crates.io/crates/yaml-rust2 / https://github.com/Ethiraric/yaml-rust2 yesterday... it forks from the latest commit on the original repository https://github.com/chyh1990/yaml-rust on 2021-07-12, and adds commits starting on 2023-08-14 and latest on 2024-02-08.

I've done a quick review and appears to be functional and in good faith, but should have more people review and confirm.

Also, strangely... @Ethiraric doesn't seem to have any means of contact posted in Github, and has issues disabled on the yaml-rust2 repository (?). Edit: resolved... see #1921 (comment)

[Ethiraric]

Heya!
Having issues disabled was (I think) an unintended side-effect of the repository being a fork in a first place and was not at all intentional.

It forks from one of the pull requests from the original yaml-rust where the author added support for the yaml test suite, a set of YAML files and their expected output. yaml-rust did not pass the whole test suite. Although most of the tests were corner cases that were unlikely to be encountered in real-world YAML, I have fixed all of them so that yaml-rust2 now correctly passes the whole suite.

I've also added a bunch of comments to the code, refactored some constructs and optimized so that the library should be faster than yaml-rust.

I have waited to produce real benchmark data before doing an announced release. I am fairly new to the art of benchmarking, and my last attempts at optimizing have failed, which is why there hasn't been any meaningful commit for a month now.

As-is, I see no reason the code would be less functional than yaml-rust, but I am human and make errors, so maybe there's something I missed, in which case a bug report (now that I have issues enabled, thanks to you) would be welcome.

If there's anything I could help with, do feel free to open an issue or send me an e-mail (I'll add that to my profile in a second, but I have a gmail address whose local part is my username here).

@davvid's https://crates.io/crates/yaml-rust-davvid is another fork that, to the best of my knowledge, is sincere.

[davvid]

Yes, I'm relying on the availability of this functionality long-term so I'd be more than happy to help maintain a fork or swap over to a different fork. I wasn't aware of yaml-rust2, thanks for bringing that to my attention.

[Ethiraric]

I've had a look at the commits on @davvid's repository, and it seems that they are mostly focused on the output API and handling of Yaml elements. If that's the case, our works should be complementary as I almost exclusively focused on the parsing side of the project.

[Ethiraric]

@davvid Our repositories should have a common ancestor in the latest yaml-rust commit.

Would it be okay with you if I tried merging your commit tree into my repository?

[davvid]

@Ethiraric that'd be great. I actually started on the merge before seeing your message and submitted the changes in a clean rebase over at Ethiraric/yaml-rust2#2

[Ethiraric]

Thank you very much for your work on this pull request! I hope we can get it to merge cleanly soon ❤️

[tarcieri]

I just wanted to say that yaml-rust appears to be implicitly unmaintained, however per our unmaintained crates policy we prefer to wait for 90 days after an issue like chyh1990/yaml-rust#197 has been opened to give the author time to respond.

If someone would like to file an unmaintained crate advisory in advance, we can merge it when that time has elapsed.

[davvid]

I'm linking these here so that folks landing here can see the full paper trail going back to 2020. I guess waiting another 3 months isn't really going to hurt (or change much) in that respect since we've already waited ~4 years.

chyh1990/yaml-rust#160

chyh1990/yaml-rust#192

[tarcieri]

Aah, with chyh1990/yaml-rust#160 especially it seems clear this crate is unmaintained as the maintenance status has already been publicly asked about without response.

Feel free to file an advisory then. It can be merged immediately.

[jayvdb]

Using the latest https://crates.io/crates/yaml-rust2 results in https://osv.dev/RUSTSEC-2021-0153

[tarcieri]

@jayvdb that would be good to report on the yaml-rust2 repo: https://github.com/Ethiraric/yaml-rust2/issues

[Ethiraric]

Sorry this is a bit out of topic but I'll reply here.

If I'm not mistaken, this refers to the encoding crate being unmaintained. A fix is already on master (though it will unfortunately require a breaking change for people using it).

[rocallahan]

Why can't yaml-rust2 take over the yaml-rust crate name? Updating the world to yaml-rust2 is going to be pretty painful. Lots of third-party crates will have to be patched, and there's the possibility of type mismatches while some crates are updated and others aren't. Also, dtolnay responded by marking serde_yaml as unmaintained :-(.

[tarcieri]

@rocallahan the author is completely non-communicative per:

• Add more maintainers chyh1990/yaml-rust#160
• Maintainers chyh1990/yaml-rust#192
• Is this crate maintained? chyh1990/yaml-rust#197
