This can be particular tricky for responses that are ambiguous such as empty responses.
|
||||
|
||||
This EIP proposes to change the `GetBlockHeaders` and the `BlockHeaders` command to include a `request_id` as shown below.
|
||||
|
||||
* `GetBlockHeaders (0x03)`
|
||||
* **Current (eth/65):** `[block: {P, B_32}, maxHeaders: P, skip: P, reverse: P in {0, 1}]`
|
||||
* **Then (eth/66)**: `[request_id: P, [block: {P, B_32}, maxHeaders: P, skip: P, reverse: P in {0, 1}]]`
|
||||
* `BlockHeaders (0x04)`
|
||||
* **Current (eth/65):** `[blockHeader_0, blockHeader_1, ...]`
|
||||
* **Then (eth/66)**: `[request_id: P, [blockHeader_0, blockHeader_1, ...]]`
|
||||
This EIP proposes to change the `GetBlockHeaders` and the `BlockHeaders` command to include a `request_id`.
|
||||
|
||||
The `request_id` is a 64-bit integer set by the client when it makes the request. On the responding side, the exact same `request_id` from the incoming request is put back into the response object.

|
||||
1. Create a list with the `request_id` being the first element.
|
||||
2. Make the second element the list that defines the whole command in the current scheme.
|
||||
|

This is consistent with the request / response pairs in the `les` protocol.

## Implementation

Trinity has a [draft PR](https://github.com/ethereum/trinity/pull/1672) with an implementation.

## Test cases
|

These testcases cover RLP-encoding of all the redefined messages types, where the `rlp` portion is the rlp-encoding of the message defined in the `data` portion.
