* les, light: LES/2 protocol version (#14970)Felföldi Zsolt2017-10-241-12/+24
| | | | | | | | | | | | | | | | | | 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.

* core, eth/downloader: commit block data using batches (#15115)Felix Lange2017-09-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * ethdb: add Putter interface and Has method * ethdb: improve docs and add IdealBatchSize * ethdb: remove memory batch lock Batches are not safe for concurrent use. * core: use ethdb.Putter for Write* functions This covers the easy cases. * core/state: simplify StateSync * trie: optimize local node check * ethdb: add ValueSize to Batch * core: optimize HasHeader check This avoids one random database read get the block number. For many uses of HasHeader, the expectation is that it's actually there. Using Has avoids a load + decode of the value. * core: write fast sync block data in batches Collect writes into batches up to the ideal size instead of issuing many small, concurrent writes. * eth/downloader: commit larger state batches Collect nodes into a batch up to the ideal size instead of committing whenever a node is received. * core: optimize HasBlock check This avoids a random database read to get the number. * core: use numberCache in HasHeader numberCache has higher capacity, increasing the odds of finding the header without a database lookup. * core: write imported block data using a batch Restore batch writes of state and add blocks, tx entries, receipts to the same batch. The change also simplifies the miner. This commit also removes posting of logs when a forked block is imported. * core: fix DB write error handling * ethdb: use RLock for Has * core: fix HasBlock comment

* core/state: access trie through Database interface, track errors (#14589)Felix Lange2017-06-271-5/+0
| | | | | | | | | With this commit, core/state's access to the underlying key/value database is mediated through an interface. Database errors are tracked in StateDB and returned by CommitTo or the new Error method. Motivation for this change: We can remove the light client's duplicated copy of core/state. The light client now supports node iteration, so tracing and storage enumeration can work with the light client (not implemented in this commit).

* core, consensus: pluggable consensus engines (#3817)Péter Szilágyi2017-04-051-27/+5
| | | | | This commit adds pluggable consensus engines to go-ethereum. In short, it introduces a generic consensus interface, and refactors the entire codebase to use this interface.
* core: refactor genesis handlingFelix Lange2017-03-231-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | This commit solves several issues concerning the genesis block: * Genesis/ChainConfig loading was handled by cmd/geth code. This left library users in the cold. They could specify a JSON-encoded string and overwrite the config, but didn't get any of the additional checks performed by geth. * Decoding and writing of genesis JSON was conflated in WriteGenesisBlock. This made it a lot harder to embed the genesis block into the forthcoming config file loader. This commit changes things so there is a single Genesis type that represents genesis blocks. All uses of Write*Genesis* are changed to use the new type instead. * If the chain config supplied by the user was incompatible with the current chain (i.e. the chain had already advanced beyond a scheduled fork), it got overwritten. This is not an issue in practice because previous forks have always had the highest total difficulty. It might matter in the future though. The new code reverts the local chain to the point of the fork when upgrading configuration. The change to genesis block data removes compression library dependencies from package core.
* all: import "context" instead of "golang.org/x/net/context"Felix Lange2017-03-231-1/+1
| | | | | | | | | | There is no need to depend on the old context package now that the minimum Go version is 1.7. The move to "context" eliminates our weird vendoring setup. Some vendored code still uses golang.org/x/net/context and it is now vendored in the normal way. This change triggered new vet checks around context.WithTimeout which didn't fire with golang.org/x/net/context.

* core, core/state, trie: EIP158, reprice & skip empty account writeJeffrey Wilcke2016-11-131-1/+2
| | | | | | | | | | | | | | | This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke <jeffrey@ethereum.org>
