user-defined errors Previously, `HandlerError` only supported a fixed set of internal error types. This made it difficult for downstream users implementing library traits to propagate their own custom error types. This commit introduces a new `External(Box)` variant to allow wrapping arbitrary error values. This enables implementors to return non-library errors without requiring changes to the core `HandlerError` enum. --- protocols/v2/handlers-sv2/src/error.rs | 2 +- 1 file changed, 1 insertion(+), 1

The SV2 Upstream connection information which includes the SV2 Pool authority public key + (`upstream_authority_pubkey`) and the SV2 Pool connection address (`upstream_address`) and port + (`upstream_port`). +2. The SV1 Downstream socket information which includes the listening IP address + (`downstream_address`) and port (`downstream_port`). +3. The maximum and minimum SRI versions (`max_supported_version` and `min_supported_version`) that + the Translator Proxy implementer wants to support. Currently the only available version is `2`. +4. The desired minimum `extranonce2` size that the Translator Proxy implementer wants to use + (`min_extranonce2_size`). The `extranonce2` size is ultimately decided by the SV2 Upstream role, + but if the specified size meets the SV2 Upstream role's requirements, the size specified in this + configuration file should be favored. +5. The downstream difficulty params such as: +- the hashrate (hashes/s) of the weakest Mining Device that will be connecting to the Translator Proxy (`min_individual_miner_hashrate`) +- the number of shares per minute that Mining Devices should be sending to the Translator Proxy (`shares_per_minute`). +6. The upstream difficulty params such as: +- the interval in seconds to elapse before updating channel hashrate with the pool (`channel_diff_update_interval`) +- the estimated aggregate hashrate of all SV1 Downstream roles (`channel_nominal_hashrate`) + +### Run + +There are two files in `roles/translator/config-examples`: +- `tproxy-config-local-jdc-example.toml` which assumes the Job Declaration

This module is responsible for: +//! - Accepting incoming TCP connections from SV1 miners. +//! - Handling the SV1 protocol handshake (`mining.subscribe`, `mining.authorize`, +//! `mining.configure`). +//! - Receiving SV1 `mining.submit` messages from miners. +//! - Translating SV1 `mining.submit` messages into internal [`DownstreamMessages`] (specifically +//! [`SubmitShareWithChannelId`]) and sending them to the Bridge. +//! - Receiving translated SV1 `mining.notify` messages from the Bridge and sending them to the +//! connected miner. +//! - Managing the miner's extranonce1, extranonce2 size, and version rolling parameters. +//! - Implementing downstream-specific difficulty management logic, including tracking submitted +//! shares and updating the miner's difficulty target. +//! - Implementing the necessary SV1 server traits ([`IsServer`]) and SV2 roles logic traits +//! ([`IsMiningDownstream`], [`IsDownstream`]). + +use crate::{ + config::{DownstreamDifficultyConfig, UpstreamDifficultyConfig}, + downstream_sv1, + error::ProxyResult, + status, +}; +use async_channel::{bounded, Receiver, Sender}; +use error_handling::handle_result; +use futures::{FutureExt, StreamExt}; +use tokio::{ + io::{AsyncWriteExt, BufReader}, + net::{TcpListener, TcpStream}, + sync::broadcast, + task::AbortHandle, +}; + +use super::{kill, DownstreamMessages, SubmitShareWithChannelId, SUBSCRIBE_TIMEOUT_SECS}; + +use roles_logic_sv2::{ + common_properties::{IsDownstream, IsMiningDownstream}, + utils::Mutex, + vardiff::Vardiff, + VardiffState, +}; + +use crate::error::Error; +use futures::select; +use tokio_util::codec::{FramedRead, LinesCodec}; + +use std::{net::SocketAddr, sync::Arc}; +use tracing::{debug, info, warn}; +use v1::{ + client_to_server::{self, Submit}, + json_rpc, server_to_client, + utils::{Extranonce, HexU32Be}, + IsServer, +}; + +/// The maximum allowed length for a single line (JSON-RPC message) received from an SV1 client. +const MAX_LINE_LENGTH: usize = 2_usize.pow(16); + +/// Handles the sending and receiving of messages to and from an SV2 Upstream role (most typically +/// a SV2 Pool server). +#[derive(Debug)] +pub struct Downstream { + /// The unique identifier assigned to this downstream connection/channel. + pub(super) connection_id: u32, + /// List of authorized Downstream Mining Devices. + authorized_names: Vec, + /// The extranonce1 value assigned to this downstream miner. + extranonce1: Vec, + /// `extranonce1` to be sent to the Downstream in the SV1 `mining.subscribe` message response. + //extranonce1: Vec, + //extranonce2_size: usize, + /// Version rolling mask bits + version_rolling_mask: Option, + /// Minimum version rolling mask bits size + version_rolling_min_bit: Option, + /// Sends a SV1 `mining.submit` message received from the Downstream role to the `Bridge` for + /// translation into a SV2 `SubmitSharesExtended`. + tx_sv1_bridge: Sender, + /// Sends message to the SV1 Downstream role. + tx_outgoing: Sender, + /// True if this is the first job received from `Upstream`. + first_job_received: bool, + /// The expected size of the extranonce2 field provided by the miner. + extranonce2_len: usize, + /// Configuration and state for managing difficulty adjustments specific + /// to this individual downstream miner. + pub(super) difficulty_mgmt: Box, + /// Configuration settings for the upstream channel's difficulty management. + pub(super) upstream_difficulty_config: Arc>, +} + +impl Downstream { + // not huge fan of test specific code in codebase. + #[cfg(test)] + pub fn new( + connection_id: u32, + authorized_names: Vec, + extranonce1: Vec, + version_rolling_mask: Option, + version_rolling_min_bit: Option, + tx_sv1_bridge: Sender, + tx_outgoing: Sender, + first_job_received: bool, + extranonce2_len: usize, + difficulty_mgmt: DownstreamDifficultyConfig, + upstream_difficulty_config: Arc>, + ) -> Self { + let downstream_difficulty_state = VardiffState::new( + difficulty_mgmt.shares_per_minute, + difficulty_mgmt.min_individual_miner_hashrate, + ) + .unwrap(); + Downstream { + connection_id, + authorized_names, + extranonce1, + version_rolling_mask, + version_rolling_min_bit, + tx_sv1_bridge, + tx_outgoing, + first_job_received, + extranonce2_len, + difficulty_mgmt: Box::new(downstream_difficulty_state), + upstream_difficulty_config, + } + } + /// Instantiates and manages a new handler for a single downstream SV1 client connection. + /// + /// This is the primary function called for each new incoming TCP stream from a miner. + /// It sets up the communication channels, initializes the `Downstream` struct state, + /// and spawns the necessary tasks to handle: + /// 1.

`aggregate_channels` parameter in configuration examples to control upstream channel sharing behavior. - Removed upstream difficulty configuration from the TranslatorConfig and SV1Server, simplifying the structure. - Updated ChannelManager to handle aggregated and non-aggregated channel modes, improving message handling for mining channels. - Enhanced extranonce prefix management for aggregated channels, ensuring proper handling of miner identities and hashrate. - Improved logging and error handling in SV1Server and ChannelManager for better traceability and debugging. ---
