Jeffrey Wilcke 6cace73bea core/vm/runtime: simplified runtime calling mechanism
Implemented `runtime.Call` which uses - unlike Execute - the given state
for the execution and the address of the contract you wish to execute.
Unlike `Execute`, `Call` requires a config.

Jeffrey Wilcke 80f26086ee core, tests: get_hash fix
Make sure that we're fetching the hash from the current chain and not
the canonical chain.

Gustav Simonsson e1616f77c7 core, core/vm, cmd/evm: remove redundant balance check 2015-10-06 12:42:34 +02:00
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.

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 184e9ae9a8 core, tests: reduced state copy by N calls
Reduced the amount of state copied that are required by N calls by doing
a balance check prior to any state modifications.

Felix Lange bfbcfbe4a9 all: fix license headers one more time
I forgot to update one instance of "go-ethereum" in commit 3f047be5a.

Felix Lange 3f047be5aa all: update license headers to distiguish GPL/LGPL
All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

obscuren 38c61f6f25 core, core/vm: added structure logging
This also reduces the time required spend in the VM
2015-06-10 12:23:49 +02:00
obscuren 1c872ddf4b Changed how logs are being recorded
Logs are now recorded per transactions instead of tossing them out after
each transaction. This should also fix an issue with
`eth_getFilterLogs` (#629) Also now implemented are the `transactionHash,
blockHash, transactionIndex, logIndex` on logs. Closes #654.
