Felföldi Zsolt	2cdf6ee7e0	light: CHT and bloom trie indexers working in light mode (#16534) ... This PR enables the indexers to work in light client mode by downloading a part of these tries (the Merkle proofs of the last values of the last known section) in order to be able to add new values and recalculate subsequent hashes. It also adds CHT data to NodeInfo.	6 years ago
Felföldi Zsolt	25982375a8	les: fix retriever logic (#16776) ... This PR fixes a retriever logic bug. When a peer had a soft timeout and then a response arrived, it always assumed it was the same peer even though it could have been a later requested one that did not time out at all yet. In this case the logic went to an illegal state and deadlocked, causing a goroutine leak. Fixes #16243 and replaces #16359. Thanks to @riceke for finding the bug in the logic.	7 years ago

Felföldi Zsolt	ca376ead88	les, light: LES/2 protocol version (#14970) ... This PR implements the new LES protocol version extensions: * new and more efficient Merkle proofs reply format (when replying to a multiple Merkle proofs request, we just send a single set of trie nodes containing all necessary nodes) * BBT (BloomBitsTrie) works similarly to the existing CHT and contains the bloombits search data to speed up log searches * GetTxStatusMsg returns the inclusion position or the pending/queued/unknown state of a transaction referenced by hash * an optional signature of new block data (number/hash/td) can be included in AnnounceMsg to provide an option for "very light clients" (mobile/embedded devices) to skip expensive Ethash check and accept multiple signatures of somewhat trusted servers (still a lot better than trusting a single server completely and retrieving everything through RPC). The new client mode is not implemented in this PR, just the protocol extension.	7 years ago
Felföldi Zsolt	a5d08c893d	les: code refactoring (#14416) ... This commit does various code refactorings: - generalizes and moves the request retrieval/timeout/resend logic out of LesOdr (will be used by a subsequent PR) - reworks the peer management logic so that all services can register with peerSet to get notified about added/dropped peers (also gets rid of the ugly getAllPeers callback in requestDistributor) - moves peerSet, LesOdr, requestDistributor and retrieveManager initialization out of ProtocolManager because I believe they do not really belong there and the whole init process was ugly and ad-hoc	8 years ago
