* Fetching logs by hash in blockchain database (#8463)
* Fetch logs by hash in blockchain database
* Fix tests
* Add unit test for branch block logs fetching
* Add docs that blocks must already be sorted
* Handle branch block cases properly
* typo: empty -> is_empty
* Remove return_empty_if_none by using a closure
* Use BTreeSet to avoid sorting again
* Move is_canon to BlockChain
* typo: pass value by reference
* Use loop and wrap inside blocks to simplify the code
Borrowed from https://github.com/paritytech/parity/pull/8463#discussion_r183453326
* typo: missed a comment
* Pass on storage keys tracing to handle the case when it is not modified (#8491)
* Pass on storage keys even if it is not modified
* typo: account and storage query
`to_pod_diff` builds both `touched_addresses` merge and storage keys merge.
* Fix tests
* Use state query directly because of suicided accounts
* Fix a RefCell borrow issue
* Add tests for unmodified storage trace
* Address grumbles
* typo: remove unwanted empty line
* ensure_cached compiles with the original signature
* Update wasmi and pwasm-utils (#8493)
* Update wasmi to 0.2
New wasmi supports 32bit platforms and no longer requires a special feature to build for such platforms.
* Update pwasm-utils to 0.1.5
* Show imported messages for light client (#8517)
* Enable WebAssembly and Byzantium for Ellaism (#8520)
* Enable WebAssembly and Byzantium for Ellaism
* Fix indentation
* Remove empty lines
* Don't panic in import_block if invalid rlp (#8522)
* Don't panic in import_block if invalid rlp
* Remove redundant type annotation
* Replace RLP header view usage with safe decoding
Using the view will panic with invalid RLP. Here we use Rlp decoding directly which will return a `Result<_, DecoderError>`. While this path currently should not have any invalid RLP - it makes it safer if ever called with invalid RLP from other code paths.
* Node table sorting according to last contact data (#8541)
* network-devp2p: sort nodes in node table using last contact data
* network-devp2p: rename node contact types in node table json output
* network-devp2p: fix node table tests
* network-devp2p: note node failure when failed to establish connection
* network-devp2p: handle UselessPeer error
* network-devp2p: note failure when marking node as useless
* move common forks and parameters to common params
* port specs over to new format
* fix RPC tests
* parity-machine skeleton
* remove block type
* extract out ethereum-specific methods into EthereumMachine
* beginning to integrate Machine into engines. dealing with stale transitions in Ethash
* initial porting to machine
* move block reward back into engine
* abstract block reward logic
* move last hash and DAO HF logic into machine
* begin making engine function parameters generic
* abstract epoch verifier and ethash block reward logic
* instantiate special ethereummachine for ethash in spec
* optional full verification in verify_block_family
* re-instate tx_filter in a way that works for all engines
* fix warnings
* fix most tests, further generalize engine trait
* uncomment nullengine, get ethcore tests compiling
* fix warnings
* update a bunch of specs
* re-enable engine signer, validator set, and transition handler
* migrate basic_authority engine
* move last hashes into executedblock
* port tendermint
* make all ethcore tests pass
* json-tests compilation
* fix RPC tests: change in gas limit for new block changed PoW hash
* fix minor grumbles
* validate chainspecs
* fix broken import
* fix transaction verification for pre-homestead
* Ethereum Classic Monetary Policy
Create a new parameter `ecip1017EraRounds`. When the block number
passes one era rounds, the reward is reduced by 20%.
See https://github.com/ethereumproject/ECIPs/blob/master/ECIPs/ECIP-1017.md
* Update rewards for uncle miners for ECIP1017
In the monetary policy, the rewards are changed from "up to 7/8 of the
reward" to "1/32 of the reward".
* Fix an off-by-one error in ECIP1017 era calculation
According to
https://github.com/ethereumproject/ECIPs/blob/master/ECIPs/ECIP-1017.md,
when in block number 5,000,000, it should still be in Era 1 (which in
our code `era == 0`). So we need to check whether the `rem` equals to
zero and act accordingly when calculating the era.
* `ecip1017_era_rounds` missing from EthashParams when run in build bot
* strip out ecip1017_eras_block_reward function and add unit test
