## Issues Addressed Closes #2739 Closes #2812 ## Proposed Changes Support the deserialization of query strings containing duplicate keys into their corresponding types. As `warp` does not support this feature natively (as discussed in #2739), it relies on the external library [`serde_array_query`](https://github.com/sigp/serde_array_query) (written by @michaelsproul) This is backwards compatible meaning that both of the following requests will produce the same output: ``` curl "http://localhost:5052/eth/v1/events?topics=head,block" ``` ``` curl "http://localhost:5052/eth/v1/events?topics=head&topics=block" ``` ## Additional Info Certain error messages have changed slightly. This only affects endpoints which accept multiple values. For example: ``` {"code":400,"message":"BAD_REQUEST: invalid query: Invalid query string","stacktraces":[]} ``` is now ``` {"code":400,"message":"BAD_REQUEST: unable to parse query","stacktraces":[]} ``` The serve order of the endpoints `get_beacon_state_validators` and `get_beacon_state_validators_id` have flipped: ```rust .or(get_beacon_state_validators_id.boxed()) .or(get_beacon_state_validators.boxed()) ``` This is to ensure proper error messages when filter fallback occurs due to the use of the `and_then` filter. ## Future Work - Cleanup / remove filter fallback behaviour by substituting `and_then` with `then` where appropriate. - Add regression tests for HTTP API error messages. ## Credits - @mooori for doing the ground work of investigating possible solutions within the existing Rust ecosystem. - @michaelsproul for writing [`serde_array_query`](https://github.com/sigp/serde_array_query) and for helping debug the behaviour of the `warp` filter fallback leading to incorrect error messages. |

Lighthouse: Ethereum 2.0
An open-source Ethereum 2.0 client, written in Rust and maintained by Sigma Prime.
Overview
Lighthouse is:
- Ready for use on Eth2 mainnet.
- Fully open-source, licensed under Apache 2.0.
- Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
- Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
- Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys, the Decentralization Foundation and private individuals.
- Actively involved in the specification and security analysis of the Ethereum 2.0 specification.
Eth2 Deposit Contract
The Lighthouse team acknowledges
0x00000000219ab540356cBB839Cbe05303d7705Fa
as the canonical Eth2 deposit contract address.
Documentation
The Lighthouse Book contains information for users and developers.
The Lighthouse team maintains a blog at lighthouse.sigmaprime.io which contains periodical progress updates, roadmap insights and interesting findings.
Branches
Lighthouse maintains two permanent branches:
stable: Always points to the latest stable release.- This is ideal for most users.
unstable: Used for development, contains the latest PRs.- Developers should base their PRs on this branch.
Contributing
Lighthouse welcomes contributors.
If you are looking to contribute, please head to the Contributing section of the Lighthouse book.
