* Revert "Fix not downloading old blocks (#8642)"
This reverts commit d1934363e7.
* Make sure only one thread actually imports old blocks.
* Add some trace timers.
* Bring back pending hashes set.
* Separate locks so that queue can happen while we are importing.
* Address grumbles.
* Mark test helpers and test-only specs as cfg(test)
* Use test-probe to conditionally compile test helpers
* Remove test probe and directly use features tag
* Update `add_license` script
* run script
* add `remove duplicate lines script` and run it
* Revert changes `English spaces`
* strip whitespaces
* Revert `GPL` in files with `apache/mit license`
* don't append `gpl license` in files with other lic
* Don't append `gpl header` in files with other lic.
* re-ran script
* include c and cpp files too
* remove duplicate header
* rebase nit
* Lots of println to figure out what eth_getBlockByNumber does/should do
* Remove debugging
* Print warnings when fetching pending blocks
When calling `eth_getBlockByNumber` with `pending`, we now print a deprecation warning and:
* if a pending block is found, use it to respond
* if no pending block is found, respond as if if was a request for `Latest`
Addresses issue #8703 (not sure if it's enough to close it tbh)
* Allow post-homestead forks to be specified in CommonParams
* Fix all json configs
* Fix test in json crate
* Fix test in ethcore
* Fix all chain configs to use tabs
Given we use tabs in .editorconfig and the majority of chain configs.
This change is done in Emacs using `mark-whole-buffer` and `indent-region`.
* 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
* Decouple "generate_metadata" logic to Engine
* 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

* Remove metadata in blockdetails
* [WIP] Implement a generic metadata architecture
* [WIP] Metadata insertion logic in BlockChain
* typo: Value -> Self::Value
* [WIP] Temporarily remove Engine::is_new_best interface
So that we don't have too many type errors.
* [WIP] Fix more type errors
* [WIP] ExtendedHeader::PartialEq
* [WIP] Change metadata type Option<Vec<u8>> to Vec<u8>
* [WIP] Remove Metadata Error
* [WIP] Clean up error conversion
* [WIP] finalized -> is_finalized
* [WIP] Mark all fields in ExtrasInsert as pub
* [WIP] Remove unused import

* 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.
* rlp::decode returns Result
* Fix journaldb to handle rlp::decode Result
* Fix ethcore to work with rlp::decode returning Result

* 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.

* 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
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
Borrowed from https://github.com/paritytech/parity/pull/8463#discussion_r183453326
* typo: missed a comment
* 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
