* Add light client TODO item
* Move existing total-difficulty-based fork choice check to Engine
* Abstract total difficulty and block provider as Machine::BlockMetadata and Machine::BlockProvider

* Use fixed BlockMetadata and BlockProvider type for null and instantseal
In this way they can use total difficulty fork choice check
* Extend blockdetails with metadatas and finalized info
* Extra data update: mark_finalized and update_metadatas
* Check finalized block in Blockchain
* Fix a test constructor in verification mod
* Add total difficulty trait
* Fix type import
* Db migration to V13 with metadata column
* Address grumbles
* metadatas -> metadata
* Use generic type for update_metadata to avoid passing HashMap all around
* Remove metadata in blockdetails
* [WIP] Implement a generic metadata architecture
* [WIP] Metadata insertion logic in BlockChain

So that we don't have too many type errors.
* [WIP] Fix more type errors

* Implement is_new_best using Ancestry iterator
* Use expect instead of panic
* [WIP] Add ancestry Engine support via on_new_block
* Fix tests
* Emission of ancestry actions
* use_short_version should take account of metadata
* Engine::is_new_best -> Engine::fork_choice
* Use proper expect format as defined in #1026
* panic -> expect
* ancestry_header -> ancestry_with_metadata
* Boxed iterator -> &mut iterator
* Fix tests
* is_new_best -> primitive_fork_choice
* Document how fork_choice works
* Engine::fork_choice -> Engine::primitive_fork_choice
* comment: clarify types of finalization where Engine::primitive_fork_choice works
* Expose FinalizationInfo to Engine
* Fix tests due to merging
* Remove TotalDifficulty trait
* Do not pass FinalizationInfo to Engine
If there's finalized blocks in from route, choose the old branch without calling `Engine::fork_choice`.
* Fix compile
* Fix unused import
* Remove is_to_route_finalized
When no block reorg passes a finalized block, this variable is always false.
* Address format grumbles
* Fix docs: mark_finalized returns None if block hash is not found
`blockchain` mod does not yet have an Error type, so we still temporarily use None here.
* Fix inaccurate tree_route None expect description
* Some tiny modifications.
1. fix some typo in the comment.
2. sort the order of methods in 'impl state::Backend for StateDB`
* Remove the clone of code_cache, as it has been done in clone_basic.
* remove From::from. It seems not necessary.
* change mode: remove rust files' executable mode.
* 2 tiny modifications on snapshot.
* Remove inject.js server-side injection for dapps
* Remove dapps test `should_inject_js`
Parity doesn't inject a <script> tag inside the responses anymore
Occasionally should_return_correct_nonces_when_dropped_because_of_limit fails, possibly because of multiple threads competing to finish. See CI logs here for an example: https://gitlab.parity.io/parity/parity/-/jobs/86738
Unpack errors and check for io::ErrorKind::InvalidInput and return our own AddressParse error. Remove the foreign link to std::net::AddrParseError and add an `impl From` for that error. Test parsing properly.
* rlp::decode returns Result
* Fix journaldb to handle rlp::decode Result
* Fix ethcore to work with rlp::decode returning Result
* Light client handles rlp::decode returning Result
* Fix tests in rlp_derive
* Fix tests
* Cleanup
* cleanup
* Allow panic rather than breaking out of iterator
* Let decoding failures when reading from disk blow up
* syntax
* Fix the trivial grumbles
* Fix failing tests
* Make Account::from_rlp return Result
* Syntx, sigh
* Temp-fix for decoding failures
* Header::decode returns Result
Handle new return type throughout the code base.
* Do not continue reading from the DB when a value could not be read
* Fix tests
* Handle header decoding in light_sync
* Handling header decoding errors
* Let the DecodeError bubble up unchanged
* Remove redundant error conversion
* Alter IO queueing.
* Don't require IoMessages to be Clone
* Ancient blocks imported via IoChannel.
* Get rid of private transactions io message.
* Get rid of deadlock and fix disconnected handler.
* Revert to old disconnect condition.
* Fix tests.
* Fix deadlock.
* Trace precompiled contracts when the transfer value is not zero
* Add tests for precompiled CALL tracing
* Use byzantium test machine for the new test
* Add notes in comments on why we don't trace all precompileds
* Use is_transferred instead of transferred
* Parity as a library
* Fix concerns
* Allow using a null on_client_restart_cb
* Fix more concerns
* Test the C library in test.sh
* Reduce CMake version to 3.5
* Move the clib test before cargo test
* Add println in test
rlp::decode returns Result
Make a best effort to handle decoding errors gracefully throughout the code, using `expect` where the value is guaranteed to be valid (and in other places where it makes sense).
* Keep all enacted blocks notify in order
* Collect is unnecessary
* Update ChainNotify to use ChainRouteType
* Fix all ethcore fn defs
* Wrap the type within ChainRoute
* Fix private-tx and sync api
* Fix secret_store API
* Fix updater API
* Fix rpc api
* Fix informant api
* Eagerly cache enacted/retracted and remove contain_enacted/retracted
* Fix indent
* tests: should use full expr form for struct constructor
* Use into_enacted_retracted to further avoid copy
* typo: not a function
* rpc/tests: ChainRoute -> ChainRoute::new
* Consolidate crypto functionality in `ethcore-crypto`.
- Move `ecdh`/`ecies` modules to `ethkey`.
- Refactor `ethcore-crypto` to use file per module.
- Replace `subtle` with `ethcore_crypto::is_equal`.
- Add `aes_gcm` module to `ethcore-crypto`.
* Rename `aes::{encrypt,decrypt,decrypt_cbc}` ...
... to `aes::{encrypt_128_ctr,decrypt_128_ctr,decrypt_128_cbc}`.
* Add SHL, SHR, SAR opcodes
* Add have_bitwise_shifting schedule flag
* Add all EIP tests for SHL
* Add SHR implementation and tests
* Implement SAR and add tests
* Add eip145transition config param
* Change map_or to map_or_else when possible
* 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.
* 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
* 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
