* 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.
* Clean up some function prototypes
why:
Simplify polymorphic prototype variances for easier maintenance.
* Fix fringe condition crash when importing bogus RLP node
why:
Accessing non-list RLP entry as a list causes `Defect`
* Fix left boundary proof at range extractor
why:
Was insufficient. The main problem was that there was no unit test for
the validity of the generated left boundary.
* Handle incomplete left boundary proofs early
why:
Attempt to do it later leads to overly complex code in order to prevent
looping when the same peer repeats to send the same incomplete proof.
Contrary, gaps in the leaf sequence can be handled gracefully with
registering the gaps
* Implement a manual pivot setup mechanism for snap sync
why:
For a test scenario it is convenient to set the pivot to something
lower than the beacon header from the consensus layer. This does not
need rely on any RPC mechanism.
details:
The file containing the pivot specs is specified by the
`--sync-ctrl-file` option. It is regularly parsed for updates.
* Fix calculation error
why:
Prevent from calculating negative square root
* Renaming androgynous sub-object names according to where they belong
why:
These objects are not explicitly dealt with. They give meaning to
some generic wrapper objects. Naming them after their origin may
help troubleshooting.
* Redefine proof nodes list data type for `snap/1` wire protocol
why:
The current specification suffered from the fact that the basic data
type for a proof node is an RLP encoded hexary node. This slightly
confused the encoding/decoding magic.
details:
This is the second attempt, now wrapping the `seq[Blob]` into a
wrapper object of `seq[SnapProof]` for a distinct alias sequence.
In the previous attempt, `SnapProof` was a wrapper object holding the
`Blob` with magic applied to the `seq[]`. This needed the `append`
mixin to strip the outer wrapper that was applied to the `Blob` already
when it was passed as argument.
* Fix some prototype inconsistency
why:
For easy reading, `getAccountRange()` handler return code should
resemble the `accoundRange()` anruments prototype.
* Fix locked database file annoyance with unit tests on Windows
why:
Need to clean up old files first from previous session as files remain
locked despite closing of database.
* Fix initialisation order
detail:
Apparently this has no real effect as the ticker is only initialised
here but started later.
This possible bug has been in all for a while and was running with the
previous compiler and libraries.
* Better naming of data fields for sync descriptors
details:
* BuddyRef[S,W]: buddy.data -> buddy.only
* CtxRef[S]: ctx.data -> ctx.pool
* Refactoring in preparation for time-based forking.
* Timestamp-based hard-fork-transition.
* Workaround SideEffect issue / compiler bug for both failing locations in Portal history code

* Redefine `seq[Blob]` => `seq[SnapProof]` for `snap/1` protocol
why:
Proof nodes are traded as `Blob` type items rather than Nim objects. So
the RLP transcoder must not extra wrap proofs which are of type
seq[Blob]. Without custom encoding one would produce a
`list(blob(item1), blob(item2) ..)` instead of `list(item1, item2 ..)`.
* Limit leaf extractor by RLP size rather than number of items
why:
To be used serving `snap/1` requests, the result of function
`hexaryRangeLeafsProof()` is limited by the maximal space
needed to serialise the result which will be part of the
`snap/1` repsonse.
* Let the range extractor `hexaryRangeLeafsProof()` return RLP list sizes
why:
When collecting accounts, the size oft the accounts list when encoded
as RLP is continually updated. So the summed up value is available
anyway. For the proof nodes list, there are not many (~ 10) so summing
up is not expensive here.
* Removed some Windows specific unit test annoyances
details:
+ Short put()/get() cycles on persistent database have a race condition
with vendor rocksdb. On a specific (and slow) qemu/win7 a 50ms `sleep()`
in between will mostly do the job (i.e. unless heavy CPU load.) This
issue was not observed on github/ci.
+ Removed annoyances when qemu/Win7 keeps the rocksdb database files
locked even after closing the db. The problem is solved by strictly
using fresh names for each test. No assumption made to be able to
properly clean up. This issue was not observed on github/ci.
* Silence some compiler gossip -- part 7, misc/non(sync or graphql)
details:
Adding some missing exception annotation
* Unit tests to verify calculations based on hard coded constants
why:
Sizes of RLP encoded objects are available at run time only.
* Changed argument order for `hexaryRangeLeafsProof()` prototype
why:
Better to read as a stand-alone function (arguments were optimised
for functional pipelines)
* Run sub-range proof tests for extracted ranges
* Cosmetics
details:
+ Update doc generator
+ Fix key type representation in `hexary_desc` for debugging
+ Redefine `isImportOk()` as template for better `check()` line reporting
* Fix fringe condition when interpolating Merkle-Patricia tries
details:
Small change with profound effect fixing some pathological condition
that haunted the unit test set on large data sers. There is still one
condition left which might well be due to an incomplete data set.
* Unit test proof nodes for node range extractor
* Unit tests to run on full extraction set
why:
Left over from troubleshooting, range length was only 5
* Reduce Nim 1.6 compiler warnings/hints for Fluffy and Nimbus proxy
Mostly raises Defect removals, TaintedString removal and some
unnecessary imports.
Also updating the copyright years alongside.
* Further reduce Nim 1.6 compiler warnings/hints for Nimbus
* 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)
* Update comments and test noise
* Fix boundary proofs
why:
Where neither used in production, nor unit tested. For production, other
methods apply to test leaf range integrity directly based of the proof
nodes.
* Added `hexary_range()`: interval range + proof extractor
details:
+ Will be used for `snap/1` protocol handler
+ Unit tests added (also for testing left boundary proof)
todo:
Need to verify completeness of proof nodes
* Reduce some nim 1.6 compiler noise
* Stop unit test gossip for ci tests
* Updated to the latest nim-eth, nim-rocksdb, nim-web3
* Bump nimbus-eth2 module and fix related issues
Temporarily disabling Portal beacon light client network as it is
a lot of copy pasted code that did not yet take into account
forks. This will require a bigger rework and was not yet tested
in an actual network anyhow.
* More nimbus fixes after module bumps

Two unresolved items currently:
- Three tests that are temporarily disabled as they fail in the
macro_assembler code, which seems to be due to an ambigious
identifier Stop (Ops and chronos ServerCommand enum).
- i386 CI disabled as it fails at Nim compilation already. Failed
tests where already ignored for this target.
why:
Clique relies on the even/odd position of an address after sorting. For
address generation, the Nim PRNG was used which seems to have changed
with Nim 1.6.11 (Linux, Windoes only.)
As a replace, the Posix.1-2001 example (two-liner calculation) generator
is used.
* Extracted RocksDB timing unit tests into separate file
why:
make space for more in main module :)
* Extracted `inspectionRunner()` unit tests into separate file
why:
make space for more in main module :)
* Extracted `storagesRunner()` unit tests into separate file
why:
make space for more in main module :)
* Extracted pivot checkpoint store/retrieval unit tests into separate file
why:
make space for more in main module :)
* Extract helper functions into separate source file
* Extracted account import unit tests into separate file
why:
make space for more in main module :)
* Rename `test_decompose()` => `test_NodeRangeDecompose()`
why:
There will be more functions with `test_NodeRange` prefix.
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
* Rename and update dismantle => hexaryEnvelopeDecompose()
why:
+ As for naming, a positive connotation is prefered
+ The unit tests were really insufficient
+ The function result was wrong on a few boundry conditions
detail:
+ Extracted the function from `hexary_paths.nim` and re-implemented
it together with other envelope functions => `hexary_envelope.nim`
+ Re-wrote docu for `hexaryEnvelopeDecompose()`
* Relaxed right condition for `hexaryEnvelopeDecompose()` range argument
why;
Previously, the right point of the argument interval had to be a path
to an allocated leaf node. While this is typically a given for accounts,
it is easier to require an arbitrary range of paths (or keys) with
the requirement of a `boundary proof` for left and right (i.e. enough
nodes in the database to find the end points.)
also:
Bug fixes for related functions (typos, missing conditions etc.)
* Add missing unit tests include file
* Add quick hexary trie inspector, called `dismantle()`
why:
+ Full hexary trie perusal is slow if running down leaf nodes
+ For known range of leaf nodes, work out the UInt126-complement of
partial sub-trie paths (for existing nodes). The result should cover
no (or only a few) sub-tries with leaf nodes.
* Extract common healing methods => `sub_tries_helper.nim`
details:
Also apply quick hexary trie inspection tool `dismantle()`
Replace `inspectAccountsTrie()` wrapper by `hexaryInspectTrie()`
* Re-arrange task dispatching in main peer worker
* Refactor accounts and storage slots downloaders
* Rename `HexaryDbError` => `HexaryError`
The `BlockHeader` structure in `nim-eth` was updated with support for
EIP-4895 (withdrawals). To enable the `nim-eth` bump, the ingress of
`BlockHeader` structures has been hardened to reject headers that have
the new `withdrawalsRoot` field until proper withdrawals support exists.
https://github.com/status-im/nim-eth/pull/562
* Stop negotiating pivot if peer repeatedly replies w/usesless answers
why:
There is some fringe condition where a peer replies with legit but
useless empty headers repetely. This goes on until somebody stops.
We stop now.
* Rename `missingNodes` => `sickSubTries`
why:
These (probably missing) nodes represent in reality fully or partially
missing sub-tries. The top nodes may even exist, e.g. as a shallow
sub-trie.
also:
Keep track of account healing on/of by bool variable `accountsHealing`
controlled in `pivot_helper.execSnapSyncAction()`
* Add `nimbus` option argument `snapCtx` for starting snap recovery (if any)
also:
+ Trigger the recovery (or similar) process from inside the global peer
worker initialisation `worker.setup()` and not by the `snap.start()`
function.
+ Have `runPool()` returned a `bool` code to indicate early stop to
scheduler.
* Can import partial snap sync checkpoint at start
details:
+ Modified what is stored with the checkpoint in `snapdb_pivot.nim`
+ Will be loaded within `runDaemon()` if activated
* Forgot to import total coverage range
why:
Only the top (or latest) pivot needs coverage but the total coverage
is the list of all ranges for all pivots -- simply forgotten.
* Piecemeal trie inspection
details:
Trie inspection will stop after maximum number of nodes visited.
The inspection can be resumed using the returned state from the
last session.
why:
This feature allows for task switch between `piecemeal` sessions.
* Extract pivot helper code from `worker.nim` => `pivot_helper.nim`
* Accounts import will now return dangling paths from `proof` nodes
why:
With proper bookkeeping, this can be used to start healing without
analysing the the probably full trie.
* Update `unprocessed` account range handling
why:
More generally, the API of a pairs of unprocessed intervals favours
the first set and not before that is exhausted the second set comes
into play.
This was unfortunately implemented which caused the ranges to be
unnecessarily fractioned. Now the number of range interval typically
remains in the lower single digit numbers.
* Save sync state after end of downloading some accounts
details:
restore/resume to be implemented later
* Update log ticker, using time interval rather than ticker count
why:
Counting and logging ticker occurrences is inherently imprecise. So
time intervals are used.
* Use separate storage tables for snap sync data
* Left boundary proof update
why:
Was not properly implemented, yet.
* Capture pivot in peer worker (aka buddy) tasks
why:
The pivot environment is linked to the `buddy` descriptor. While
there is a task switch, the pivot may change. So it is passed on as
function argument `env` rather than retrieved from the buddy at
the start of a sub-function.
* Split queues `fetchStorage` into `fetchStorageFull` and `fetchStoragePart`
* Remove obsolete account range returned from `GetAccountRange` message
why:
Handler returned the wrong right value of the range. This range was
for convenience, only.
* Prioritise storage slots if the queue becomes large
why:
Currently, accounts processing is prioritised up until all accounts
are downloaded. The new prioritisation has two thresholds for
+ start processing storage slots with a new worker
+ stop account processing and switch to storage processing
also:
Provide api for `SnapTodoRanges` pair of range sets in `worker_desc.nim`
* Generalise left boundary proof for accounts or storage slots.
why:
Detailed explanation how this works is documented with
`snapdb_accounts.importAccounts()`.
Instead of enforcing a left boundary proof (which is still the default),
the importer functions return a list of `holes` (aka node paths) found in
the argument ranges of leaf nodes. This in turn is used by the book
keeping software for data download.
* Forgot to pass on variable in function wrapper
also:
+ Start healing not before 99% accounts covered (previously 95%)
+ Logging updated/prettified
* Added basic async capabilities for vm2.
This is a whole new Git branch, not the same one as last time
(https://github.com/status-im/nimbus-eth1/pull/1250) - there wasn't
much worth salvaging. Main differences:
I didn't do the "each opcode has to specify an async handler" junk
that I put in last time. Instead, in oph_memory.nim you can see
sloadOp calling asyncChainTo and passing in an async operation.
That async operation is then run by the execCallOrCreate (or
asyncExecCallOrCreate) code in interpreter_dispatch.nim.
In the test code, the (previously existing) macro called "assembler"
now allows you to add a section called "initialStorage", specifying
fake data to be used by the EVM computation run by that test. (In
the long run we'll obviously want to write tests that for-real use
the JSON-RPC API to asynchronously fetch data; for now, this was
just an expedient way to write a basic unit test that exercises the
async-EVM code pathway.)
There's also a new macro called "concurrentAssemblers" that allows
you to write a test that runs multiple assemblers concurrently (and
then waits for them all to finish). There's one example test using
this, in test_op_memory_lazy.nim, though you can't actually see it
doing so unless you uncomment some echo statements in
async_operations.nim (in which case you can see the two concurrently
running EVM computations each printing out what they're doing, and
you'll see that they interleave).
A question: is it possible to make EVMC work asynchronously? (For
now, this code compiles and "make test" passes even if ENABLE_EVMC
is turned on, but it doesn't actually work asynchronously, it just
falls back on doing the usual synchronous EVMC thing. See
FIXME-asyncAndEvmc.)
* Moved the AsyncOperationFactory to the BaseVMState object.
* Made the AsyncOperationFactory into a table of fn pointers.
Also ditched the plain-data Vm2AsyncOperation type; it wasn't
really serving much purpose. Instead, the pendingAsyncOperation
field directly contains the Future.
* Removed the hasStorage idea.
It's not the right solution to the "how do we know whether we
still need to fetch the storage value or not?" problem. I
haven't implemented the right solution yet, but at least
we're better off not putting in a wrong one.
* Added/modified/removed some comments.
(Based on feedback on the PR.)
* Removed the waitFor from execCallOrCreate.
There was some back-and-forth in the PR regarding whether nested
waitFor calls are acceptable:
https://github.com/status-im/nimbus-eth1/pull/1260#discussion_r998587449
The eventual decision was to just change the waitFor to a doAssert
(since we probably won't want this extra functionality when running
synchronously anyway) to make sure that the Future is already
finished.
* Re-arrange fetching storage slots in batch module
why;
Previously, fetching partial slot ranges first has a chance of
terminating the worker peer 9due to network error) while there were
many inheritable storage slots on the queue.
Now, inheritance is checked first, then full slot ranges and finally
partial ranges.
* Update logging
* Bundled node information for healing into single object `NodeSpecs`
why:
Previously, partial paths and node keys were kept in separate variables.
This approach was error prone due to copying/reassembling function
argument objects.
As all partial paths, keys, and node data types are more or less handled
as `Blob`s over the network (using Eth/6x, or Snap/1) it makes sense to
hold these `Blob`s as named field in a single object (even if not all
fields are active for the current purpose.)
* For good housekeeping, using `NodeKey` type only for account keys
why:
previously, a mixture of `NodeKey` and `Hash256` was used. Now, only
state or storage root keys use the `Hash256` type.
* Always accept latest pivot (and not a slightly older one)
why;
For testing it was tried to use a slightly older pivot state root than
available. Some anecdotal tests seemed to suggest an advantage so that
more peers are willing to serve on that older pivot. But this could not
be confirmed in subsequent tests (still anecdotal, though.)
As a side note, the distance of the latest pivot to its predecessor is
at least 128 (or whatever the constant `minPivotBlockDistance` is
assigned to.)
* Reshuffle name components for some file and function names
why:
Clarifies purpose:
"storages" becomes: "storage slots"
"store" becomes: "range fetch"
* Stash away currently unused modules in sub-folder named "notused"
* Re-model persistent database access
why:
Storage slots healing just run on the wrong sub-trie (i.e. the wrong
key mapping). So get/put and bulk functions now use the definitions
in `snapdb_desc` (earlier there were some shortcuts for `get()`.)
* Fixes: missing return code, typo, redundant imports etc.
* Remove obsolete debugging directives from `worker_desc` module
* Correct failing unit tests for storage slots trie inspection
why:
Some pathological cases for the extended tests do not produce any
hexary trie data. This is rightly detected by the trie inspection
and the result checks needed to adjusted.
* For snap sync, publish `EthWireRef` in sync descriptor
why:
currently used for noise control
* Detect and reuse existing storage slots
* Provide healing module for storage slots
* Update statistic ticker (adding range factor for unprocessed storage)
* Complete mere function for work item ranges
why:
Merging interval into existing partial item was missing
* Show av storage queue lengths in ticker
detail;
Previous attempt shows average completeness which did not tell much
* Correct the meaning of the storage counter (per pivot)
detail:
Is the # accounts that have a storage saved
* Rename `LeafRange` => `NodeTagRange`
* Replacing storage slot partition point by interval
why:
The partition point only allows to describe slots `[point,high(Uint256)]`
for fetching interval slot ranges. This has been generalised for any
interval.
* Replacing `SnapAccountRanges` by `SnapTrieRangeBatch`
why:
Generalised healing status for accounts, and later for storage slots.
* Improve accounts healing loop
* Split `snap_db` into accounts and storage modules
why:
It is cleaner to have separate session descriptors for accounts and
storage slots (based on a common base descriptor.)
Also, persistent storage handling might be changed in future which
requires the storage slot implementation disentangled from the accounts
handling.
* Re-model worker queues for storage slots
why:
There is a dynamic list of storage sub-tries, each one has to be
treated similar to the accounts database. This applied to slot
interval downloads as well as to healing
* Compress some return value report lists for snapdb methods
why:
No need to report all handling details for work items that are filteres
out and discarded, anyway.
* Remove inner loop frame from healing function
why:
The healing function runs as a loop body already.
* Split fetch accounts into sub-modules
details:
There will be separated modules for accounts snapshot, storage snapshot,
and healing for either.
* Allow to rebase pivot before negotiated header
why:
Peers seem to have not too many snapshots available. By setting back the
pivot block header slightly, the chances might be higher to find more
peers to serve this pivot. Experiment on mainnet showed that setting back
too much (tested with 1024), the chances to find matching snapshot peers
seem to decrease.
* Add accounts healing
* Update variable/field naming in `worker_desc` for readability
* Handle leaf nodes in accounts healing
why:
There is no need to fetch accounts when they had been added by the
healing process. On the flip side, these accounts must be checked for
storage data and the batch queue updated, accordingly.
* Reorganising accounts hash ranges batch queue
why:
The aim is to formally cover as many accounts as possible for different
pivot state root environments. Formerly, this was tried by starting the
accounts batch queue at a random value for each pivot (and wrapping
around.)
Now, each pivot environment starts with an interval set mutually
disjunct from any interval set retrieved with other pivot state roots.
also:
Stop fishing for more pivots in `worker` if 100% download is reached
* Reorganise/update accounts healing
why:
Error handling was wrong and the (math. complexity of) whole process
could be better managed.
details:
Much of the algorithm is now documented at the top of the file
`heal_accounts.nim`
* 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.
* Bump nim-stew
why:
Need fixed interval set
* Keep track of accumulated account ranges over all state roots
* Added comments and explanations to unit tests
* typo
* Extracted functionality into sub-modules for maintainability
* Setting SST bulk load as default in `accounts_db`
details:
+ currently, the same data are stored via rocksdb if available, and
the same via embedded `storage_type` with (non-standard) prefix 200
for time comparisons
+ fallback to normal `put()` unless rocksdb is accessible
* Provided common scheduler API, applied to `full` sync
* Use hexary trie as storage for proofs_db records
also:
+ Store metadata with account for keeping track of account state
+ add iterator over accounts
* Common scheduler API applied to `snap` sync
* Prepare for accounts bulk import
details:
+ Added some ad-hoc checks for proving accounts data received from the
snap/1 (will be replaced by proper database version when ready)
+ Added code that dumps some of the received snap/1 data into a file
(turned of by default, see `worker_desc.nim`)
* Added sepolia specs
* temporarily avoid latest `master` branch from `nim-eth1`
why:
Currently does not cleanly compile after the `bearssl` split api update.
* 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.
* Use type name eth and snap (rather than snap1)
* Prettified snap/eth handler trace messages
* Regrouped sync sources
details:
Snap storage related sources are moved to common directory.
Option --new-sync renamed to --snap-sync
also:
Normalised logging for secondary/non-protocol handlers.
* Merge protocol wrapper files => protocol.nim
details:
Merge wrapper sync/protocol_ethxx.nim and sync/protocol_snapxx.nim
into single file snap/protocol.nim
* Comments cosmetics
* Similar start logic for blockchain_sync.nim and sync/snap.nim
* Renamed p2p/blockchain_sync.nim -> sync/fast.nim
* Update exception tracinig
* Use lazy JSON parser
why:
Uint246 type is not directly supported by the JSON serializer
* Json parser update for stringified UInt256 integers
why:
Now available
* update sub-module branch reference
* 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
* Enable JWT authentication for websockets
details:
Currently, this is optional and only enabled when the jwtsecret option
is set.
There is a default mechanism to generate a JWT secret if it is not
explicitly stated. This mechanism is currently unused.
* Make JWT authentication compulsory for websockets
* Fix unit test entry point + cosmetics
* Update JSON-RPC link
* Improvements as suggested by Mamy
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.
* De-noisify some Clique logging
why:
Too annoying when syncing against Goerly
* Replay devnet# and kiln sessions
why:
Compiled as local program, the unit test was used for TDD.
* dist: precompiled binaries and Docker images
The builds are reproducible, the binaries are portable and statically link librocksdb.
This took some patching. Upstream PR: https://github.com/facebook/rocksdb/pull/9752
32-bit ARM is missing as a target because two different GCC versions
fail with an ICE when trying to cross-compile RocksDB. Using Clang
instead is too much trouble for a platform that nobody should be using
anyway.
(Clang doesn't come with its own target headers and libraries, can't be
easily convinced to use the ones from GCC, so it needs an fs image from
a 32-bit ARM distro - at which point I stopped caring).
* CI: disable reproducibility test
* Activate wire protocol eth/66
and:
Disentangle protocol_eth66.nim from import sections
why:
Importing the protocol_eth66 module is not necessary. There is
no need to know too many details of the underlying wire protocol. All
that is needed will be exported by blockchain_sync.nim.
* fixes, and rebase
* Update nimbus/p2p/blockchain_sync.nim

* Fixes and rebase
Co-authored-by: Kim De Mey <kim.demey@gmail.com>
why:
TDD data and test script that are not needed for CI are externally held.
This saves space.
also:
Added support for test-custom_networks.nim to run import Devnet5 dump.
* Rearrange/rename test_kintsugu => test_custom_network
why:
Debug, fix and test more general problems related to running
nimbus on a custom network.
* Update UInt265/Json parser for --custom-network command line option
why:
As found out with the Kintsugi configuration, block number and balance
have the same Nim type which led to misunderstandings. This patch makes
sure that UInt265 encoded string values "0x11" decodes to 17, and "b"
and "11" to 11.
* Refactored genesis.toBlock() => genesis.toBlockHeader()
why:
The function toBlock(g,db) may return different results depending on
whether the db descriptor argument is nil, or initialised. This is due
to the db.config data sub-descriptor which may give various outcomes
for the baseFee field of the genesis header.
Also, the version where db is non-nil initialised is used internally
only. So the public rewrite toBlockHeader() that replaces the toBlock()
function expects a full set of NetworkParams.
* update comments
* Rename toBlockHeader() => toGenesisHeader()
why:
Polymorphic prototype used for BaseChainDB or NetworkParams argument.
With a BaseChainDB descriptor argument, the name shall imply that the
header is generated from the config fields rather than fetched from
the database.
* Added command line option --static-peers-file
why:
Handy feature to keep peer nodes in a file, similar to the
--bootstrap-file option.
* Kludge needed for setting up custom network
why:
Some non-features in the persistent hexary trie DB produce an assert
error when initiating the Kinsugi network.
details:
This fix should be temporary, only.
* Fix OS detection
why:
directive detectOs() bails out on Windows if checking for Ubuntu
* test environment for studying crash of hexary trie
why:
the persistent test case will crash unless in genesis.toBlock():
+ pruneTrie is set false, or
+ the directive "tdb.put(emptyRlpHash.data,emptyRlp)" is added right
before the "for k, v in account.storage:" loop
* different tests for OS variants
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.
* Redesign of BaseVMState descriptor
why:
BaseVMState provides an environment for executing transactions. The
current descriptor also provides data that cannot generally be known
within the execution environment, e.g. the total gasUsed which is
available not before after all transactions have finished.
Also, the BaseVMState constructor has been replaced by a constructor
that does not need pre-initialised input of the account database.
also:
Previous constructor and some fields are provided with a deprecated
annotation (producing a lot of noise.)
* Replace legacy directives in production sources
* Replace legacy directives in unit test sources
* fix CI (missing premix update)
* Remove legacy directives
* chase CI problem
* rebased
* Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation
why:
Constructing a new 'AccountsCache' descriptor can be avoided sometimes
when the current state root is properly positioned already. Such a
feature existed already as the update function 'initStateDB()' for the
'BaseChanDB' where the accounts cache was linked into this desctiptor.
The function 'initStateDB()' was removed and re-implemented into the
'BaseVmState' constructor without optimisation. The old version was of
restricted use as a wrong accounts cache state would unconditionally
throw an exception rather than conceptually ask for a remedy.
The optimised 'BaseVmState' re-initialisation has been implemented for
the 'persistBlocks()' function.
also:
moved some test helpers to 'test/replay' folder
* Remove unused & undocumented fields from Chain descriptor
why:
Reduces attack surface in general & improves reading the code.
details:
1. The check for cumulativeGasUsed + tx.gasLimit <= header.gasLimit
makes neither sense nor is it part of the Eip1559 specs. Nevertheless
a check tx.gasLimit <= header.gasLimit is added to satisfy some
unit test (see comments in validateTransaction() body.)
2. As a replacement check for the one removed in 1, a check for
cumulativeGasUsed + gasBurned <= header.gasLimit has been added
(see comments in processTransactionImpl() body.)
3. Prototypes for processTransaction() variants have been cleaned up and
commented.
why:
Detail 1. in particular produces an error for tightly packed blocks when
the last tx in the list has a generous gasLimit.
* crash test scenario
details:
Example code for inspecting nested block chain and accounts cache
database transaction framework. There seems to be a pathological
case where the system crashes after a rollback (as appeared in the
tx-pool packer code.)
* simplified crash scenario
* Workable solution (as suggested by Andri)
details:
Avoiding db.rollback() (db.commit() is OK) while vmState.stateDB is
alive.
* Rename text_txcrash => test_accounts_cache
why:
Unit tests covers part of accounts_cache handling
* comment update
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.

* PoW wrapper for verification & mining
why:
It eases data management of per-Epoch lookup tables. Also some unit
tests show limits of usefulness on non-specialised machines for
mining besides developing tests.
details:
For PoW verification, this patch provides a pretty wrapper hiding the
details of the ethash/Hashimoto lookup cache management.
For mining on my development system without special hardware, the
underlying ethash functions are prohibitively slow. It takes
* ~20 minutes to prepare the full ethash/Hashimoto lookup dataset
* a second to run ~25k nonce tests (in the mining loop)
The mining part might be of some use for generating test data for
the tx-pool, though.
* Using PowRef as replacement for EpochHashCache + hashimotoLight()
* Fix typo (CI failed)
why:
was below log level when testing locally
* fix canonical naming
previously, every time the VMState was created, it will also create
new stateDB, and this action will nullify the advantages of cached accounts.
the new changes will conserve the accounts cache if the executed blocks
are contiguous. if not the stateDB need to be reinited.
this changes also allow rpcCallEvm and rpcEstimateGas executed properly
using current stateDB instead of creating new one each time they are called.
EIP-2718:
- chainID: Long! of Query
- chainID: Long of Transaction
EIP-1559:
- baseFeePerGas: BigInt of Block
- effectiveGasPrice: BigInt of Transaction
- maxFeePerGas: BigInt of Transaction
- maxPriorityFeePerGas: BigInt of Transaction
this is a preparation for migration to confutils based config
although there is still some getConfiguration usage in tests code
it will be removed after new config arrived
although they are technically different, but in reality,
many networks are using the same id for ChainId dan NetworkId.
in this commit, we set networkid from config file's chainId.
- allow clique period and epoch to be configured via config file
- this also activate poaEngine mode
- remove clique period configuration from cli to reduce confusion
- fix#786
