Trevor Porter	9a83eb4d57	Sequence-aware indexing refactor (#3262) ... ### Description Part 1 of an indexing refactor. This mostly focuses on the sequence-aware cursors. Changes: - Some renames, e.g. `SequenceIndexer` -> `SequenceAwareIndexer`, `sequence_and_tip` -> `latest_sequence_count_and_tip` - Moved cursors out of `contract_sync/cursor.rs` into `contract_sync/cursors/*` - The goal was to make the the Forward sequence-aware cursor, the Backward sequence-aware, and the ForwardBackward sequence aware cursors more resilient, easier to understand, and better tested. - General strategy for doing this was to: - Only move onto a new range to index if the logs passed into the cursor's `update` function justify this - If updated with any weird data, like gaps in logs, rewind the cursor and retry previously queried ranges I'd recommend starting the review in the following order: 1. `rust/hyperlane-base/src/contract_sync/cursors/sequence_aware/forward.rs` - where `ForwardSequenceAwareSyncCursor` & tests live 2. `rust/hyperlane-base/src/contract_sync/cursors/sequence_aware/backward.rs` - where `BackwardSequenceAwareSyncCursor` & tests live 3. `rust/hyperlane-base/src/contract_sync/cursors/sequence_aware/mod.rs` - where `ForwardBackwardSequenceAwareSyncCursor` lives ### Drive-by changes <!-- Are there any minor or drive-by changes also included? --> ### Related issues <!-- - Fixes #[issue number here] --> ### Backward compatibility <!-- Are these changes backward compatible?

Daniel Savu	f2a0e92c7f	Cosmos grpc fallbackprovider (#3139) ... ### Description Implements grpc fallback provider logic for cosmos - initially tried implementing the fallback provider deprioritization logic at middleware level like in the EVM. The difference between ethers and cosmrs is that in the latter, middleware can only live at the transport layer (`tower` crate level). - based on this github [issue](https://github.com/hyperium/tonic/issues/733), that actually doesn't look possible, because the http::Request type isn't `Clone` so it can't be submitted to multiple providers - ended up implementing the fallback provider at the application layer, by keeping an array of grpc channels - There is now a `call` method in `hyperlane_core::FallbackProvider` which I'm actually really happy with. This method handles the fallbackprovider-specific logic by taking in an async closure, running it on each provider, and iterating providers if the closure call fails. In `grpc.rs` you can see how this is slightly verbose but I think it's quite manageable. The only part that bugs me is having to duplicate `Pin::from(Box::from(future))`, but that's need afaict because the regular closure returns an anonymous type - adds `grpcUrls` and `customGrpcUrls` config items - tests the cosmos fallback provider e2e ### Drive-by changes <!-- Are there any minor or drive-by changes also included? --> ### Related issues - Fixes: https://github.com/hyperlane-xyz/issues/issues/998 ### Backward compatibility <!-- Are these changes backward compatible?
