In this commit, the RPC API is adapted to run on top of the new Go API.
This required lots of changes to many packages, but has a few side
benefits:
- Ethereum and LightEthereum can now be used as a contract backend.
- Some duplicated code could be removed (there is added duplication in
other places though)
- It is now much easier to see which operations are unsupported with the
light client. Package les previously relied on the full node RPC API
backend, which masked several issues because the RPC API performed
direct access to the chain database.
Changes to packages in detail:
accounts/abi/bind:
- Contract call boilerplate has moved to package core.
cmd/utils:
- les now inherits the event.TypeMux from the Node instance
contracts/release:
- The ReleaseService now uses Ethereum and LightEthereum as backend.
core:
- MissingNumber is exposed so it can be used in package eth.
- GetTransaction now returns the index as an int, for convenience
reasons.
- ApplyCallMessage has been added as the new one and only
implementation of read-only contract calls.
- TxPool exposes NonceAt instead of the more general accessor for the
ManagedState.
core/types:
- Signer.SignECDSA is gone (it was basically unused).
- WithSignature doesn't return an error anymore (all implementations panic for
invalid length). I made this change to avoid code duplication in the API.
eth:
- EthApiBackend is gone. In its place, Ethereum gains many new methods
which implement a large portion of the new Go API. It does not
yet support event subscriptions and log filtering.
- Some accessors for internal objects are gone.
- ethapi.PrivateDebugAPI and ethapi.TxPoolDebugAPI are now created in
package eth for dependency reasons.
eth/downloader:
- Progress returns a pointer to simplify callers.
eth/filters:
- The Backend interface is simpler and uses the stable Go API where
possible. The new BlockReceipts method saves one DB read because
BlockReceipts also takes a block number argument.
- ChainDB is no longer passed via the Backend interface.
- EventSystem now relies on HeaderByHash for reorgs in light client mode
instead of reading from the chain database.
eth/gasprice:
- The LightPriceOracle now uses ethereum.ChainReader instead of
ethapi.Backend.
ethclient:
- TransactionByHash is adapted for the last-minute API change which
adds the isPending return value.
internal/ethapi:
- PublicTxPoolAPI is now called TxPoolDebugAPI, moved to its own file
and talks to the transaction pool instead of using the main Backend.
- The API no longer accesses the chain database directly. All access
is mediated through Backend methods.
- The backend is now split into three interfaces.
Implementing Backend is mandatory but does not require the pending
state. The other two (PendingState, TransactionInclusionBlock) are
optional and discovered at runtime.
les:
- LesApiBackend is gone, LightEthereum gets all the methods.
- Weird accessors copied from package eth are now gone as well.
light:
- TxPool.Stats now returns a queued count of zero. It implements the
ethapi.TxPool interface and can be used with TxPoolDebugAPI.
* core, core/types: refactored tx chain id checking
Refactored explicit chain id checking in to the Sender deriviation method
* cmd/utils, params: define chain ids
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

whisper: project restructured, version 5 introduced
This commits adds a draft version of the new shh v5 protocol.
The new version is not on by default, --shh still selects version 2.
This commit converts the dependency management from Godeps to the vendor
folder, also switching the tool from godep to trash. Since the upstream tool
lacks a few features proposed via a few PRs, until those PRs are merged in
(if), use github.com/karalabe/trash.
You can update dependencies via trash --update.
All dependencies have been updated to their latest version.
Parts of the build system are reworked to drop old notions of Godeps and
invocation of the go vet command so that it doesn't run against the vendor
folder, as that will just blow up during vetting.
The conversion drops OpenCL (and hence GPU mining support) from ethash and our
codebase. The short reasoning is that there's noone to maintain and having
opencl libs in our deps messes up builds as go install ./... tries to build
them, failing with unsatisfied link errors for the C OpenCL deps.
golang.org/x/net/context is not vendored in. We expect it to be fetched by the
user (i.e. using go get). To keep ci.go builds reproducible the package is
"vendored" in build/_vendor.
This implements 1b & 1c of EIP150 by adding a new GasTable which must be
returned from the RuleSet config method. This table is used to determine
the gas prices for the current epoch.
Please note that when the CreateBySuicide gas price is set it is assumed
that we're in the new epoch phase.
In addition this PR will serve as temporary basis while refactorisation
in being done in the EVM64 PR, which will substentially overhaul the gas
price code.
The redirect check did not work on Go 1.6 and below because Stat
returned an error for stdout and stderr. In Go 1.7 Stat works on stdout
but doesn't return anything meaningful, causing cmd/geth test failures
because the message is printed to stderr only. Fix it by printing to
stdout only.
This change also deletes generator.go, moving the only interesting line
in it into release.go. The binding has been regenerated with abigen from
develop and solc v0.3.6.
The account manager was previously created by packge cmd/utils as part
of flag processing and then passed down into eth.Ethereum through its
config struct. Since we are starting to create nodes which do not have
eth.Ethereum as a registered service, the code was rearranged to
register the account manager as its own service. Making it a service is
ugly though and it doesn't really fix the root cause: creating nodes
without eth.Ethereum requires duplicating lots of code.
This commit splits utils.MakeSystemNode into three functions, making
creation of other node/service configurations easier. It also moves the
account manager into Node so it can be used by those configurations
without requiring package eth.
