From ca376ead88a5a26626a90abdb62f4de7f6313822 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Felf=C3=B6ldi=20Zsolt?= Date: Tue, 24 Oct 2017 15:19:09 +0200 Subject: 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. --- light/odr_test.go | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'light/odr_test.go') diff --git a/light/odr_test.go b/light/odr_test.go index c0c5438fd..e6afb1a48 100644 --- a/light/odr_test.go +++ b/light/odr_test.go @@ -77,7 +77,9 @@ func (odr *testOdr) Retrieve(ctx context.Context, req OdrRequest) error { req.Receipts = core.GetBlockReceipts(odr.sdb, req.Hash, core.GetBlockNumber(odr.sdb, req.Hash)) case *TrieRequest: t, _ := trie.New(req.Id.Root, odr.sdb) - req.Proof = t.Prove(req.Key) + nodes := NewNodeSet() + t.Prove(req.Key, 0, nodes) + req.Proof = nodes case *CodeRequest: req.Data, _ = odr.sdb.Get(req.Hash[:]) } -- cgit v1.2.3
