| | | | | | | | | | * common: delete StringToAddress, StringToHash These functions are confusing because they don't parse hex, but use the bytes of the string.

* les, light: LES/2 protocol version (#14970)Felföldi Zsolt2017-10-242-6/+9
| | | | | | | | | | | | | | | | | | 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/bloombits, eth/filters: handle null topics (#15195)Péter Szilágyi2017-09-275-46/+26
| | | | | | | | | | When implementing the new bloombits based filter, I've accidentally broke null topics by removing the special casing of common.Hash{} filter rules, which acted as the wildcard topic until now. This PR fixes the regression, but instead of using the magic hash common.Hash{} as the null wildcard, the PR reworks the code to handle nil topics during parsing, converting a JSON null into nil []common.Hash topic.

* core: refactor genesis handlingFelix Lange2017-03-232-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | 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 Lange2017-03-235-11/+8
| | | | | | | | | | 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.
* event: deprecate TypeMux and related typesFelix Lange2017-01-251-2/+2

* core/vm: move Log to core/typesFelix Lange2017-01-065-75/+70
| | | | | | | | This significantly reduces the dependency closure of ethclient, which no longer depends on core/vm as of this change. All uses of vm.Logs are replaced by []*types.Log. NewLog is gone too, the constructor simply returned a literal.
* eth/filters: add FindOnce for iterator-like operation (#3435)Nick Johnson2016-12-201-20/+50
| | | | | | | | | | | This commit introduces a FindOnce method for filters. FindOnce finds the next block that matches the filter and returns all matching logs from that block. If there are no further matching logs, it returns a nil slice. This method allows callers to iterate over large sets of logs progressively. The changes introduce a small inefficiency relating to mipmaps: the first time a filter is called, it acts as if all mipmaps are matched, and thus iterates several blocks near the requested start point. This is in the interest of simplicity and avoiding duplicate mipmap lookups each time FindOnce is called.
* core, core/vm, eth/filters: move Removed field into vm.LogFelix Lange2016-12-054-109/+63
| | | | | | | | | | | | This field used to be assigned by the filter system and returned through the RPC API. Now that we have a Go client that uses the underlying type, the field needs to move. It is now assigned to true when the RemovedLogs event is generated so the filter system doesn't need to care about the field at all. While here, remove the log list from ChainSideEvent. There are no users of this field right now and any potential users could subscribe to RemovedLogsEvent instead.

| | | | | | | | | | | | | | | 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>
* core/types: remove header accessorsFelix Lange2016-11-091-2/+2
| | | | | | These accessors were introduced by light client changes, but the only method that is actually used is GetNumberU64. This commit replaces all uses of .GetNumberU64 with .Number.Uint64.

* eth/filters: added notifications for out of bound log eventsJeffrey Wilcke2016-02-054-26/+132
| | | | | | Out of Bound log events are events that were removed due to a fork. When logs are received the filtering mechanism should check for the `removed` field on the json structure.

| | | | | | | Log filtering is now using a MIPmap like approach where addresses of logs are added to a mapped bloom bin. The current levels for the MIP are in ranges of 1.000.000, 500.000, 100.000, 50.000, 1.000. Logs are therefor filtered in batches of 1.000.

The VM now depends on a Database interface returned by the environment. In the process the core now depends less on the statedb by usage of the env * Moved `Log` from package `core/state` to package `core/vm`.
* core, event/filter, xeth: refactored filter systemJeffrey Wilcke2015-10-032-0/+344
Moved the filtering system from `event` to `eth/filters` package and removed the `core.Filter` object. The `filters.Filter` object now requires a `common.Database` rather than a `eth.Backend` and invokes the `core.GetBlockByX` directly rather than thru a "manager".
