bas-vk	4e36b1e3da	core: bugfix state change race condition in txpool (#3412) ... The transaction pool keeps track of the current nonce in its local pendingState. When a new block comes in the pendingState is reset. During the reset it fetches multiple times the current state through the use of the currentState callback. When a second block comes in during the reset its possible that the state changes during the reset. If that block holds transactions that are currently in the pool the local pendingState that is used to determine nonces can get out of sync.	8 years ago

Felix Lange	56ed6152a1	core, eth, miner: improve shutdown synchronisation ... Shutting down geth prints hundreds of annoying error messages in some cases. The errors appear because the Stop method of eth.ProtocolManager, miner.Miner and core.TxPool is asynchronous. Left over peer sessions generate events which are processed after Stop even though the database has already been closed. The fix is to make Stop synchronous using sync.WaitGroup. For eth.ProtocolManager, in order to make use of WaitGroup safe, we need a way to stop new peer sessions from being added while waiting on the WaitGroup. The eth protocol Run function now selects on a signaling channel and adds to the WaitGroup only if ProtocolManager is not shutting down. For miner.worker and core.TxPool the number of goroutines is static, WaitGroup can be used in the usual way without additional synchronisation.	9 years ago

Felix Lange	6c73a59806	eth: limit number of sent transactions based on message size ... Nodes that are out of sync will queue many transactions, which causes the initial transactions message to grow very large. Larger transactions messages can make communication impossible if the message is too big to send. Big transactions messages also exhaust egress bandwidth, which degrades other peer connections. The new approach to combat these issues is to send transactions in smaller batches. This commit introduces a new goroutine that handles delivery of all initial transaction transfers. Size-limited packs of transactions are sent to one peer at a time, conserving precious egress bandwidth.	10 years ago

obscuren	05715f27cf	eth: added a cancel method for the downloader ...
