* Log/trace cancellation events in scheduler
* Provide `clear()` functions for explicitly flushing data objects
* Renaming header cache functions
why:
More systematic, all functions start with prefix `dbHeader`
* Remove `danglingParent` from layout
why:
Already provided by header cache
* Remove `couplerHash` and `headHash` from layout
why:
No need to cache, `headHash` is unused and `couplerHash` used typically
once, only.
* Remove `lastLayout` from sync descriptor
why:
No need to compare changes, saving is always triggered after actively
changing the sync layout state
* Early reject unsuitable head + finalised header from CL
why:
The finalised header is only passed by its hash so the header must be
fetched somewhere, e.g. from a peer via eth/xx.
Also, finalised headers earlier than the `base` from `FC` cannot be
handled due to the `Aristo` single state database architecture.
Luckily, on a full node, the complete block history is available so
unsuitable finalised headers are stored there already which is exploited
here to avoid unnecessary network traffic.
* Code cosmetics, remove cruft, prettify logging, remove `final` metrics
detail:
The `final` layout parameter will be deprecated and later removed
* Update/re-calibrate syncer logic documentation
why:
The current implementation sucks if the `FC` module changes the
canonical branch in the middle of completing a header chain (due
to concurrent updates by the `newPayload()` logic.)
* Implement according to re-calibrated syncer docu
details:
The implementation employs the notion of named layout states (see
`SyncLayoutState` in `worker_desc.nim`) which are derived from the
state parameter triple `(C,D,H)` as described in `README.md`.
When walking AriVtx, parsing integers and nibbles actually becomes a
hotspot - these trivial changes reduces CPU usage during initial key
cache computation by ~15%.
Currently, computed hash keys are stored in a separate column family
with respect to the MPT data they're generated from - this has several
disadvantages:
* A lot of space is wasted because the lookup key (`RootedVertexID`) is
repeated in both tables - this is 30% of the `AriKey` content!
* rocksdb must maintain in-memory bloom filters and LRU caches for said
keys, doubling its "minimal efficient cache size"
* An extra disk traversal must be made to check for existence of cached
hash key
* Doubles the amount of files on disk due to each column family being
its own set of files
Here, the two CFs are joined such that both key and data is stored in
`AriVtx`. This means:
* we save ~30% disk space on repeated lookup keys
* we save ~2gb of memory overhead that can be used to cache data instead
of indices
* we can skip storing hash keys for MPT leaf nodes - these are trivial
to compute and waste a lot of space - previously they had to present in
the `AriKey` CF to avoid having to look in two tables on the happy path.
* There is a small increase in write amplification because when a hash
value is updated for a branch node, we must write both key and branch
data - previously we would write only the key
* There's a small shift in CPU usage - instead of performing lookups in
the database, hashes for leaf nodes are (re)-computed on the fly
* We can return to slightly smaller on-disk SST files since there's
fewer of them, which should reduce disk traffic a bit
Internally, there are also other advantages:
* when clearing keys, we no longer have to store a zero hash in memory -
instead, we deduce staleness of the cached key from the presence of an
updated VertexRef - this saves ~1gb of mem overhead during import
* hash key cache becomes dedicated to branch keys since leaf keys are no
longer stored in memory, reducing churn
* key computation is a lot faster thanks to the skipped second disk
traversal - a key computation for mainnet can be completed in 11 hours
instead of ~2 days (!) thanks to better cache usage and less read
amplification - with additional improvements to the on-disk format, we
can probably get rid of the initial full traversal method of seeding the
key cache on first start after import
All in all, this PR reduces the size of a mainnet database from 160gb to
110gb and the peak memory footprint during import by ~1-2gb.
* Fixes related to Prague execution requests
Turn out the specs are changed:
- WITHDRAWAL_REQUEST_ADDRESS -> WITHDRAWAL_QUEUE_ADDRESS
- CONSOLIDATION_REQUEST_ADDRESS -> CONSOLIDATION_QUEUE_ADDRESS
- DEPOSIT_CONTRACT_ADDRESS -> only mainnet
- depositContractAddress can be configurable
Also fix bugs related to t8n tool
* Fix for evmc
* Remove two simple sleeps from history network test
Replace simple sleeps in test_history_network with retries +
sleeps. Current simple sleep setting would occasionally still
fail on CI.
* Increase retries on test_portal_testnet from 2 to 3.
* Add 1 second sleep after headers with proof get gossiped
- Move any validation related code to new file
- Move any type conversion related code to new file
- Prepare validation code for adding different type of canonical
proofs
- Prepare for validation code for json-rpc api
- several other clean-ups and renames
Sort of a first pass as the validation code specifically can
use some further changes.
* Feature: User configurable extraData when assemble a block
As evident from https://holesky.beaconcha.in/block/2657016
when nimbus-eth1 assemble a block, the extraData field is empty.
This commit will give user a chance to put his extraData or
use default value.
* Warning if extraData exceeds 32 bytes limit
* Add missing comma
* Annotate `async` functions for non-exception tracking at compile time
details:
This also requires some additional try/except catching in the function
bodies.
* Update sync logic docu to what is to be updated
why:
The understanding of details of how to accommodate for merging
sub-chains of blocks or headers have changed. Some previous set-ups
are outright wrong.
* Add two, not so great, quick fix attempts for flaky CI
* Another attempt
* Remove the increased sleep in test_history_network
Need something better here.
* Remove getSszDecoded from ContentDb.
* Update ContentDb get to use onData callback to reduce copies.
* Use templates for helper procs in ContentDb.
* Add contains handler to portal protocol.
* Improve performance of DbGetHandler.
This kind of data is not used except in tests where it is used only to
create databases that don't match actual usage of aristo.
Removing simplifies future optimizations that can focus on processing
specific leaf types more efficiently.
A casualty of this removal is some test code as well as some proof
generation code that is unused - on the surface, it looks like it should
be possible to port both of these to the more specific data types -
doing so would ensure that a database written by one part of the
codebase can interact with the other - as it stands, there is confusion
on this point since using the proof generation code will result in a
database of a shape that is incompatible with the rest of eth1.
* Clear rejected sync target so that it would not be processed again
* Use in-memory table to stash headers after FCU import has started
why:
After block imported has started, there is no way to save/stash block
headers persistently. The FCU handlers always maintain a positive
transaction level and in some instances the current transaction is
flushed and re-opened.
This patch fixes an exception thrown when a block header has gone
missing.
* When resuming sync, delete stale headers and state
why:
Deleting headers saves some persistent space that would get lost
otherwise. Deleting the state after resuming prevents from race
conditions.
* On clean start hibernate sync `deamon` entity before first update from CL
details:
Only reduces services are running
* accept FCU from CL
* fetch finalised header after accepting FCY (provides hash only)
* Improve text/meaning of some log messages
* Revisit error handling for useless peers
why:
A peer is abandoned from if the error score is too high. This was not
properly handled for some fringe case when the error was detected at
staging time but fetching via eth/xx was ok.
* Clarify `break` meaning by using labelled `break` statements
* Fix action how to commit when sync target has been reached
why:
The sync target block number might precede than latest FCU block number.
This happens when the engine API squeezes in some request to execute
and import subsequent blocks.
This patch fixes and assert thrown when after reaching target the latest
FCU block number is higher than the expected target block number.
* Update TODO list
* switch to Nim v2.0.12
* fix LruCache capitalization for styleCheck
* KzgProof/KzgCommitment for styleCheck
* TxEip4844 for styleCheck
* styleCheck issues in nimbus/beacon/payload_conv.nim
