Adds a new
TxStorecomponent that stores all unconfirmed transactions, with two implementations: an in-memory one and a LevelDB-backed one. Transactions are stored ordered by increasing nonce. Whenever a transactions is sent, it is added to the store.RelayServer has now a
UpdateUnconfirmedTransactionsmethod for updating the transactions on the store. This process removes all transactions from the store that have been confirmed (ie mined at least 12 blocks ago). If the transaction with the lowest nonce is pending (ie not mined) after 5 minutes, it is resent with an increased gas price (25% extra, with a max cap), and its timestamp is reset.This method is now invoked every minute from the RelayHTTPServer.
