svm-rs just released a new version requiring 1.89 to compile. This process to
not install _any_ software with 1.85 to minimize how many toolchains we have in
use.
Long-shot premised on an old forum post on how downgrading to Docker 24 solved
their instance of the error we face, though our conditions for it are
presumably different.
Restores using ubuntu-latest.
Basically, at some point in the last year the existing Docker e2e tests started
failing. I'm unclear if this is an issue with the OS, the docker packages, or
what. This just tries to find a solution.
coordinator/tributary was tributary-chain. This crate has been renamed
tributary-sdk and moved to coordinator/tributary-sdk.
coordinator/src/tributary was our instantion of a Tributary, the Transaction
type and scan task. This has been moved to coordinator/tributary.
The main reason for this was due to coordinator/main.rs becoming untidy. There
is now a collection of clean, independent APIs present in the codebase.
coordinator/main.rs is to compose them. Sometimes, these compositions are a bit
silly (reading from a channel just to forward the message to a distinct
channel). That's more than fine as the code is still readable and the value
from the cleanliness of the APIs composed far exceeds the nits from having
these odd compositions.
This breaks down a bit as we now define a global database, and have some APIs
interact with multiple other APIs.
coordinator/src/tributary was a self-contained, clean API. The recently added
task present in coordinator/tributary/mod.rs, which bound it to the rest of the
Coordinator, wasn't.
Now, coordinator/src is solely the API compositions, and all self-contained
APIs are their own crates.
Not only cleans the existing cosign code but enables non-Serai-coordinators to
evaluate cosigns if they gain access to a feed of them (such as over an RPC).
This would let centralized services not only track the finalized chain yet the
cosigned chain without directly running a coordinator.
Still being wrapped up.
