* Recreating some of the speculative-execution code.
Not really using it yet. Also there's some new inefficiency in
memory.nim, but it's fixable - just haven't gotten around to it yet.
The big thing introduced here is the idea of "cells" for stack,
memory, and storage values. A cell is basically just a Future (though
there's also the option of making it an Identity - just a simple
distinct wrapper around a value - if you want to turn off the
asynchrony).
* Bumped nim-eth.
* Cleaned up a few comments.
* Bumped nim-secp256k1.
* Oops.
* Fixing a few compiler errors that show up with EVMC enabled.
simplify EVM and delegete those things to accounts cache.
also no more manual state clearing, accounts cache will be
responsible for both collecting touched account and perform
state clearing.
* Part of EIP-4895: add withdrawals processing to block processing.
* Refactoring: extracted the engine API handler bodies into procs.
Intending to implement the V2 versions next. (I need the bodies to be
in separate procs so that multiple versions can use them.)
* Working on Engine API changes for Shanghai.
* Updated nim-web3, resolved ambiguity in Hash256 type.
* Updated nim-eth3 to point to master, now that I've merged that.
* I'm confused about what's going on with engine_client.
But let's try resolving this Hash256 ambiguity.
* Still trying to fix this conflict with the Hash256 types.
* Does this work now that nimbus-eth2 has been updated?
* Corrected blockValue in getPayload responses back to UInt256.
c834f67a37
* Working on getting the withdrawals-related tests to pass.
* Fixing more of those Hash256 ambiguities.
(I'm not sure why the nim-web3 library introduced a conflicting type
named Hash256, but right now I just want to get this code to compile again.)
* Bumped a couple of libraries to fix some error messages.
* Needed to get "make fluffy-tools" to pass, too.
* Getting "make nimbus_verified_proxy" to build.
* Silence some compiler gossip -- part 5, common
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 6, db, rpc, utils
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 7, randomly collected source files
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 8, assorted tests
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Clique update
why:
More impossible exceptions (undoes temporary fix from previous PR)
The `BlockHeader` structure in `nim-eth` was updated with support for
EIP-4844 (danksharding). To enable the `nim-eth` bump, the ingress of
`BlockHeader` structures has been hardened to reject headers that have
the new `excessDataGas` field until proper EIP4844 support exists.
https://github.com/status-im/nim-eth/pull/570
* Added inspect module
why:
Find dangling references for trie healing support.
details:
+ This patch set provides only the inspect module and some unit tests.
+ There are also extensive unit tests which need bulk data from the
`nimbus-eth1-blob` module.
* Alternative pivot finder
why:
Attempt to be faster on start up. Also tying to decouple pivot finder
somehow by providing different mechanisms (this one runs in `single`
mode.)
* Use inspect module for healing
details:
+ After some progress with account and storage data, the inspect facility
is used to find dangling links in the database to be filled nose-wise.
+ This is a crude attempt to cobble together functional elements. The
set up needs to be honed.
* fix scheduler to avoid starting dead peers
why:
Some peers drop out while in `sleepAsync()`. So extra `if` clauses
make sure that this event is detected early.
* Bug fixes causing crashes
details:
+ prettify.toPC():
int/intToStr() numeric range over/underflow
+ hexary_inspect.hexaryInspectPath():
take care of half initialised step with branch but missing index into
branch array
* improve handling of dropped peers in alternaive pivot finder
why:
Strange things may happen while querying data from the network.
Additional checks make sure that the state of other peers is updated
immediately.
* Update trace messages
* reorganise snap fetch & store schedule
* Re-implemented `hexaryFollow()` in a more general fashion
details:
+ New name for re-implemented `hexaryFollow()` is `hexaryPath()`
+ Renamed `rTreeFollow()` as `hexaryPath()`
why:
Returning similarly organised structures, the results of the
`hexaryPath()` functions become comparable when running over
the persistent and the in-memory databases.
* Added traversal functionality for persistent ChainDB
* Using `Account` values as re-packed Blob
* Repack samples as compressed data files
* Produce test data
details:
+ Can force pivot state root switch after minimal coverage.
+ For emulating certain network behaviour, downloading accounts stops for
a particular pivot state root if 30% (some static number) coverage is
reached. Following accounts are downloaded for a later pivot state root.
* Relocated `IntervalSets` to nim-stew repo
* Accumulate accounts on temporary kv-DB
why:
Explore the data as returned from snap/1. Will be converted to a
`eth/db` next.
details:
Verify and accumulate per/state-root accounts downloaded via snap.
also:
Some unit tests
* Replace `Table` by `TrieDatabaseRef` for accounts accumulator
* update ticker statistics
details:
mean/variance based counter update
* allow persistent db for proved accounts
* rebase, and globally activate unit test
* fix statistics
* Using `IntervalSet` type data for `LeafRange`
* Updated log ticker
* Update to `eth67`
details:
Disabled by default, use `ENABLE_LEGACY_ETH66=0` to enable
No support for `Get/NodeData` dialogue via eth, anymore
* Dissolved fetch/common.nim
details;
the log/ticker part becomes ticker.nim
the interval range management is merged into fetch.nim
* Updated account scheduler
why:
The previous scheduler fetched each account once (for different state
roots.) The updated scheduler re-calibrates after a change of the state
root and potentially (until told otherwise) fetches all possible
accounts.
* Fix `high(P)` fringe cases in `IntervalSet` handling
why:
The `high(P)` value for a point type `P` cannot be represented with
half open intervals `[a,b)` for a,b points of `P`. So this single value
needs extra treatment which was slightly wrong.
* Updated docu/comments
also:
rebased
* Update scheduler
details:
Change the `pivot` management when creating new accounts lists. It is
strictly increasing (and wrapping around) depending on last updated
accounts list.
* Prepare unit tests for running without tx-pool job queue
why:
Most of the job queue logic can be emulated. This adapts to a few
pathological test cases.
* Replace tx-pool job queue logic with in-place actions
why:
This additional execution layer is not needed, anymore which has been
learned from working with the integration/hive tests.
details:
Execution of add or deletion jobs are executed in-place. Some actions
-- as in smartHead() -- have been combined for facilitating the correct
order actions
* Update production functions, remove txpool legacy stuff
result.gasPrice = baseFee + min(result.maxPriorityFee, result.maxFee - baseFee)
cannot be simplified into
result.gasPrice = min(result.maxPriorityFee + baseFee, result.maxFee)
the expression is not commutative
why:
Causes havoc in most bit fringe cases.
details:
When setting the head forward, the delta was wrongly registered from
the static "left" end (which limits the loop) rather than the moving
"right" end.
* Fix database sort order for local txs
why:
For convenience, packed txs were stored in the block sorted by
rank->nonce. Using local accounts, the greedy grabber uses the sort
order (local,non-local)->rank->nonce which leads to a wrong calculation
of the txRoot.
* Housekeeping
details:
Replaced a couple of local eip1559TxNormalization() functions by a
single public
* Support for local accounts
why:
Accounts tagged local will be packed with priority over untagged
accounts
* Added functions for queuing txs and simultaneously setting account locality
why:
Might be a popular task, in particular for unconditionally adding txs to
a local (aka prioritised account) via "xp.addLocal(tx,true)"
caveat:
Untested yet
* fix typo
* backup
* No baseFee for pre-London tx in verifier
why:
The packer would wrongly discard valid legacy txs.
why:
Testing against a replay unit test for Devnet4 made it necessary to
adjust the TTD handling. Without updated, importing fails at block #5646
which is the parent of the terminal PoW block. Similar considerations
apply for Devnet5 and Kiln.
Includes a simple test harness for the merge interop M1 milestone
This aims to enable connecting nimbus-eth2 to nimbus-eth1 within
the testing protocol described here:
https://github.com/status-im/nimbus-eth2/blob/amphora-merge-interop/docs/interop_merge.md
To execute the work-in-progress test, please run:
In terminal 1:
tests/amphora/launch-nimbus.sh
In terminal 2:
tests/amphora/check-merge-test-vectors.sh
details:
For documentation, see comments in the file tx_pool.nim.
For prettified manual pages run 'make docs' in the nimbus directory and
point your web browser to the newly created 'docs' directory.
why:
Previous version was based on lru_cache which is ugly. This module is
based on the stew/keyed_queue library module.
other:
There are still some other modules rely on lru_cache which should be
removed.
Add the new [Arrow Glacier fork](https://eips.ethereum.org/EIPS/eip-4345).
Only the difficulty calculation is changed, but as a new fork it still affects
a number of places in the code.
To the best of my knowledge the change is only scheduled on Mainnet.
In addition:
- The fork date comments in `chain_config.nim` have been checked against the
real networks, set consistently in UTC instead of random timezones, and made
neater. Maybe we'll keep these when transferring config to a file someday.
- It's added to forkid hash tests (EIP-2124/EIP-2364), of course.
