* les, light: LES/2 protocol version (#14970)Felföldi Zsolt2017-10-246-74/+571
| | | | | | | | | | | | | | | | | | 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.

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 Lange2017-06-2711-1230/+365
| | | | | | | | | 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).

| | | | | 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 Lange2017-03-234-64/+33
| | | | | | | | | | | | | | | | | | | | | | | | 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 Lange2017-03-2312-26/+39
| | | | | | | | | | 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.

There should be no change in semantics for BigPow, BigMin, BigMax, S256, U256, Exp and their behaviour is now locked in by tests. The BigD, BytesToBig and Bytes2Big functions don't provide additional value, all uses are replaced by new(big.Int).SetBytes(). BigToBytes is now called PaddedBigBytes, its minimum output size parameter is now specified as the number of bytes instead of bits. The single use of this function is in the EVM's MSTORE instruction. Big and String2Big are replaced by ParseBig, which is slightly stricter. It previously accepted leading zeros for hexadecimal inputs but treated decimal inputs as octal if a leading zero digit was present. ParseUint64 is used in places where String2Big was used to decode a uint64. The new functions MustParseBig and MustParseUint64 are now used in many places where parsing errors were previously ignored. * common: delete unused big integer variables * accounts/abi: replace uses of BytesToBig with use of encoding/binary * common: remove BytesToBig * common: remove Bytes2Big * common: remove BigTrue * cmd/utils: add BigFlag and use it for error-checked integer flags While here, remove environment variable processing for DirectoryFlag because we don't use it. * core: add missing error checks in genesis block parser * common: remove String2Big * cmd/evm: use utils.BigFlag * common/math: check for 256 bit overflow in ParseBig This is supposed to prevent silent overflow/truncation of values in the genesis block JSON. Without this check, a genesis block that set a balance larger than 256 bits would lead to weird behaviour in the VM. * cmd/utils: fixup import

* core/vm: improved EVM run loop & instruction calling (#3378)Jeffrey Wilcke2017-01-051-2/+2
| | | | | | | | | | | | | | | The run loop, which previously contained custom opcode executes have been removed and has been simplified to a few checks. Each operation consists of 4 elements: execution function, gas cost function, stack validation function and memory size function. The execution function implements the operation's runtime behaviour, the gas cost function implements the operation gas costs function and greatly depends on the memory and stack, the stack validation function validates the stack and makes sure that enough items can be popped off and pushed on and the memory size function calculates the memory required for the operation and returns it. This commit also allows the EVM to go unmetered. This is helpful for offline operations such as contract calls.

* | core: bugfix state change race condition in txpool (#3412)bas-vk2016-12-111-2/+2
|/ | | | | | | | 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.
* core, core/vm: implemented a generic environment (#3348)Jeffrey Wilcke2016-12-064-103/+40

The new environment is suitable to be used en the json tests, core consensus and light client.
