Optimize caching in CI

opened 12:45AM - 21 Oct 22 UTC

In CI, we use the [Swatinem/rust-cache](https://github.com/Swatinem/rust-cache) …GitHub Action to cache certain build artifacts across runs. However, it seems from the README that we might be using it in a suboptimal way. A few observations: - Zerocopy has only one dependency, and `rust-cache` only caches dependencies, not crate artifacts (note that zerocopy-derive has more dependencies - and dependencies that are expensive to compile - so presumably benefits much more than zerocopy) - We generate a custom cache key which includes: - A hash of the Cargo features, but this presumably shouldn't have any effect on dependencies (at least in our case, since none of our Cargo features depend on dependencies' Cargo features) - A hash of `**/Cargo.lock`, but this is documented to be the default behavior anyway We should: - Figure out if there's a way to squeeze more benefit out for zerocopy (can we get `rust-cache` to cache any more artifacts?) - Don't include Cargo features in the cache - Don't include a hash of `**/Cargo.lock` in the cache - Go back over our use of `rust-cache` and its README with a fine toothed comb and see what else we're doing suboptimally cc @Swatinem in case there's anything obvious that jumps out at you!

In Boa, the JavaScript engine written in Rust, are taking part in Hacktoberfest, and we would like some help in some issues.

Especially in those that are causing the engine a panic.

Hi!

I have a few issues for people interested in smart meters (or just parsers):

Hi everyone

There are quite a few open issues on pest if anyone's interested: Issues · pest-parser/pest · GitHub

Perhaps to highlight one for the upcoming week's call: RFC: Make white-space handling less confusing / more consistent with the introduction of an "adjacent selector": `,` · Issue #271 · pest-parser/pest · GitHub

There are also two issues for the pest's website if anyone's into Wasm (as highlighted on v2.5.0: introducing `pest_debugger` · Discussion #739 · pest-parser/pest · GitHub ):

I'd like to see more testing of impl-tools.

It supports a number of things, including a more flexible #[derive], impl Self syntax, auto trait implementation over generic types, and singleton! { .. }.

There have been some good suggestions (better support for new-type wrappers, better error messages). Keep them coming!

Hello! Could we have a couple of Ockam issues included in this week's call for participation?

We have more beginner-friendly issues available similar to the two described above.

Thank you!

Hi again, we have new good first issues at Ockam this week! It would be awesome if they could be included in the newsletter

Thanks

Hello Everyone, I am one of the autors of Meilisearch and I would like to know if it would be possible to ask for help on these four issues?

When the `lat` and `lng` are strings the wrong error message is returned · Issue #3007 · meilisearch/meilisearch · GitHub
Bad latitude / Bad longitude should share a common message between the invalid sort and invalid filter · Issue #3006 · meilisearch/meilisearch · GitHub
When both `lat` and `lng` are missing it doesn't return the right error · Issue #3005 · meilisearch/meilisearch · GitHub
We must return an error for when `_geo` is not an object · Issue #3003 · meilisearch/meilisearch · GitHub
