From e6e63fbed20042bc1a5885c5ac9111373a1344be Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Mon, 7 Jul 2025 12:56:47 +0000 Subject: [PATCH 01/15] Implement round-robin RPC client with cooldown mechanism - Replace sequential endpoint iteration with round-robin selection - Add cooldown mechanism to temporarily avoid failed endpoints - Maintain endpoint health state and timing information - Add configurable cooldown duration (default 30 seconds) - Preserve existing API compatibility with new _and_cooldown variants - Improve resilience by distributing load across healthy endpoints Co-Authored-By: Ali --- src/agent/utils/rpc_multi_client.rs | 393 +++++++++++++++++++++------- 1 file changed, 305 insertions(+), 88 deletions(-) diff --git a/src/agent/utils/rpc_multi_client.rs b/src/agent/utils/rpc_multi_client.rs index 7cc5fbc..dedceb2 100644 --- a/src/agent/utils/rpc_multi_client.rs +++ b/src/agent/utils/rpc_multi_client.rs @@ -17,32 +17,105 @@ use { transaction::Transaction, }, solana_transaction_status::TransactionStatus, - std::time::Duration, + std::{ + sync::{Arc, Mutex}, + time::{Duration, Instant}, + }, url::Url, };
