This preparation is needed for subsequent
EIPs included in London.
- Add London to Fork enum
- Block number to fork
- Parsing London fork in chain config
- Prepare gas costs table for London
- Prepare EVM opcode dispatcher for London
- Block rewards for London
- Prepare hive script for London
* Re-adjust canonical head to parent of block to be inserted
why:
of the failing tests that remain to be solved, 30 of those will succeed
if the canonical database chain head is cleverly adjusted -- yes, it
looks like a hack, indeed.
details:
at the moment, this hack works for the non-hive tests only and is
triggered by a boolean argument passed on to the chain.persistBlocks()
method.
* Use parent instead of canonical head for block to be inserted
why:
side chains need to be inserted typically somewhere before the
canonical head.
details:
the previous _hack_ was unnecessary and removed, it was inspired by
some verification in persistBlocks() which explicitly referenced the
canonical head (which now might or might not refer to the newly inserted
header.)
* remove unnecessary code + comment
additional flags we use:
- [x] HIVE_NETWORK_ID network ID number to use for the eth protocol
- [x] HIVE_LOGLEVEL client loglevel (0-5)
- [x] HIVE_GRAPHQL_ENABLED enables graphql on port 8545
hive always set 'HIVE_FORK_DAO_VOTE' to '1'.
set 'daoForkSupport' to 'true' if only 'HIVE_FORK_DAO_BLOCK'
is set by hive, not depends only on 'HIVE_FORK_DAO_VOTE'.
This is because 'nimbus-eth1' internal is different compared to 'geth'.
now we have hive simulators written in nim:
- ethereum/consensus
- ethereum/graphql
Using these simulators, we can debug test cases without have to run
hive or docker.
this changes is required due to recent #654.
custom genesis and chain config parser are fixed
and the genesis fields are grouped into "genesis"
field, similar with chain config fields,
they are grouped in "config" field.
trying Jacek suggestion in #591, I added nat setting to
nimbus-eth1 hive shell script. visible difference after adding
this flag is the nat library not complaining about
"the gateway does not support nat-pmp" anymore.
but the slow startup time described in #591 is yet to be measured
again, although I already see improvement when executing
ethereum/consensus category in hive.
- Explain some of the prerequisites in more detail (Go version).
- Practical issues around Go version and Docker configuration to make it work.
- Make the first example be one that works with nimbus-eth1.
(Instead of giving an obscure error message that looks like the user's Docker
setup is broken).
- Rename to `README.md` per convention.
