Jeffrey Wilcke 10ed107ba2 Merge pull request #1899 from obscuren/mipmap-bloom
core, eth/filters, miner, xeth: Optimised log filtering
2015-10-16 12:35:24 -07:00
Jeffrey Wilcke 6dc14788a2 core, eth/filters, miner, xeth: Optimised log filtering
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.

core, core/vm: refactor
2015-10-05 07:14:01 -07:00
Jeffrey Wilcke 7c7692933c cmd/geth, cmd/utils, core, rpc: renamed to blockchain
* Renamed ChainManager to BlockChain
* Checkpointing is no longer required and never really properly worked
when the state was corrupted.
2015-10-04 01:13:56 +02:00
Jeffrey Wilcke 361082ec4b cmd/evm, core/vm, test: refactored VM and core
* Moved `vm.Transfer` to `core` package and changed execution to call
`env.Transfer` instead of `core.Transfer` directly.
* core/vm: byte code VM moved to jump table instead of switch
* Moved `vm.Transfer` to `core` package and changed execution to call
  `env.Transfer` instead of `core.Transfer` directly.
* Byte code VM now shares the same code as the JITVM
* Renamed Context to Contract
* Changed initialiser of state transition & unexported methods
* Removed the Execution object and refactor `Call`, `CallCode` &
  `Create` in to their own functions instead of being methods.
* Removed the hard dep on the state for the VM. 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`.

Jeffrey Wilcke f7a71996fb core, event/filter, xeth: refactored filter system
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".

Jeffrey Wilcke eaa4473dbd core, core/types: readd transactions after chain re-org
Added a `Difference` method to `types.Transactions` which sets the
receiver to the difference of a to b (NOTE: not a **and** b).

Transaction pool subscribes to RemovedTransactionEvent adding back to
those potential missing from the chain.

When a chain re-org occurs remove any transactions that were removed
from the canonical chain during the re-org as well as the receipts that
were generated in the process.

Closes #1746

Jeffrey Wilcke b8ca0a830e eth, trie: removed key prefixing from state entries & merge db fix
Fixed database merge strategy to use the correct database. Due to a copy
paste fail when doing type evaluation the same database was being
iterated (chain), all others were ignored.

Removed state prefixing because {H(code): code} is stored in the same
database as the rest of the state.
