Andrew Jones 6654d02163 [beta] Backports (#8624)
* Trace precompiled contracts when the transfer value is not zero (#8486)

* 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

* Return error if RLP size of transaction exceeds the limit (#8473)

* Return error if RLP size of transaction exceeds the limit

* Review comments fixed

* RLP check moved to verifier, corresponding pool test added

* Don't block sync when importing old blocks (#8530)

* 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.

* Refactoring `ethcore-sync` - Fixing warp-sync barrier (#8543)

* Start dividing sync chain : first supplier method

* WIP - updated chain sync supplier

* Finish refactoring the Chain Sync Supplier

* Create Chain Sync Requester

* Add Propagator for Chain Sync

* Add the Chain Sync Handler

* Move tests from mod -> handler

* Move tests to propagator

* Refactor SyncRequester arguments

* Refactoring peer fork header handler

* Fix wrong highest block number in snapshot sync

* Small refactor...

* Address PR grumbles

* Retry failed CI job

* Fix tests

* PR Grumbles

* Handle socket address parsing errors (#8545)

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.

* Fix packet count when talking with PAR2 peers (#8555)

* Support diferent packet counts in different protocol versions.

* Fix light timeouts and eclipse protection.

* Fix devp2p tests.

* Fix whisper-cli compilation.

* Fix compilation.

* Fix ethcore-sync tests.

* Revert "Fix light timeouts and eclipse protection."

This reverts commit 06285ea8c1d9d184d809f64b5507aece633da6cc.

* Increase timeouts.

* Add whisper CLI to the pipelines (#8578)

* Add whisper CLI to the pipelines

* Address todo, ref #8579

* Rename `whisper-cli binary` to `whisper` (#8579)

* rename whisper-cli binary to whisper

* fix tests

* Remove manually added text to the errors (#8595)

These messages were confusing for the users especially the help message.

* Fix account list double 0x display (#8596)

* Remove unused self import

* Fix account list double 0x display

* Fix BlockReward contract "arithmetic operation overflow" (#8611)

* Fix BlockReward contract "arithmetic operation overflow"

* Add docs on how execute_as_system works

* Fix typo

* Rlp decode returns Result (#8527)

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).

* Remove expect (#8536)

* Remove expect and propagate rlp::DecoderErrors as TrieErrors

* Decoding headers can fail (#8570)

* 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

* fix compiler warning (#8590)

* Attempt to fix intermittent test failures (#8584)

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

* block_header can fail so return Result (#8581)

* block_header can fail so return Result

* Restore previous return type based on feedback

* Fix failing doc tests running on non-code

* Block::decode() returns Result (#8586)

* Gitlab test script fixes (#8573)

* Exclude /docs from modified files.

* Ensure all references in the working tree are available

* Remove duplicated line from test script
