Jeffrey Wilcke f0cbebb19f core: added basic chain configuration
Added chain configuration options and write out during genesis database
insertion. If no "config" was found, nothing is written to the database.

Configurations are written on a per genesis base. This means
that any chain (which is identified by it's genesis hash) can have their
own chain settings.

Jeffrey Wilcke 14013372ae core: Added EVM configuration options
The EVM is now initialised with an additional configured object that
allows you to turn on debugging options.

Jeffrey Wilcke 342ae7ce7d core, core/vm, tests: changed the initialisation behaviour of the EVM
The EVM was previously initialised and created for every CALL, CALLCODE,
DELEGATECALL and CREATE. This PR changes this behaviour so that the same
EVM can be used through the session and beyond as long as the
Environment sticks around.

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.
