Database checkpointing can take seconds, e.g., while Geth is syncing.
Add a debug log + metric for it, and also info log if it takes longer
than 250ms, same as for the existing `State replayed` log. If the log
shows up for a user while the system is not overloaded, it may point
to slow disk speed or thermal issue.
Make raised exceptions explicit in `ncli_common.nim`, and handle more of
them in `ncli_db.nim` to have better UX when directories cannot be read
or file names do not parse against the expected format.
`simutils.nim` is quite outdated w.r.t. code style. Apply the following:
- Use string concatenation instead of `strformat` for simple cases
- Catch `IOError` and `SerializationError` when loading/saving SSZ files
- Catch `ValueError` for remaining `strformat` usage
- Consistently use `chronicles` in `loadGenesis`
* compute post-merge randao mix without loading state
* avoid copying state on shuffling computation and compute epochref
* speed up state copy for block production
With checkpoint sync, the checkpoint block is typically unavailable at
the start, and only backfilled later. To avoid treating it as having
zero hash, execution disabled in some contexts, wrap the result of
`loadExecutionBlockHash` in `Opt` and handle block hash being unknown.

When syncing, we log a notice each time someone asks us for a block that
we haven't backfilled yet. This is quite verbose and not unexpected,
because the status message does not allow indicating backfill progress.
When using checkpoint sync, only checkpoint state is available, block is
not downloaded and backfilled later.
`dag.backfill` tracks latest filled `slot`, and latest `parent_root` for
which no block has been synced yet.
In checkpoint sync, this assumption is broken, because there, the start
`dag.backfill.slot` is set based on checkpoint state slot, and the block
is also not available.
However, sync manager in backward mode also requests `dag.backfill.slot`
and `block_clearance` then backfills the checkpoint block once it is
synced. But, there is no guarantee that a peer ever sends us that block.
They could send us all parent blocks and solely omit the checkpoint
block itself. In that situation, we would accept the parent blocks and
advance `dag.backfill`, and subsequently never request the checkpoint
block again, resulting in gap inside blocks DB that is never filled.
To mitigate that, the assumption is restored that `dag.backfill.slot`
is the latest filled `slot`, and `dag.backfill.parent_root` is the next
block that needs to be synced. By setting `slot` to `tail.slot + 1` and
`parent_root` to `tail.root`, we put a fake summary into `dag.backfill`
so that `block_clearance` only proceeds once checkpoint block exists.
After checkpoint sync, historical block IDs cannot yet be queried.
However, they are needed to compute dependent roots of `ShufflingRef`.
To allow lookup, enable `getBlockIdAtSlot` to answer from compatible
states in memory; as long as they descend from the finalized checkpoint
and the requested slot is sufficiently recent, `block_roots` contains
everything to recover `BlockSlotId` up to `SLOTS_PER_HISTORICAL_ROOT`.
This is similar to how `attester_dependent_root` etc. are computed.
This accelerates the first couple minutes of checkpoint sync on Mainnet,
especially the time until finality advances past the synced checkpoint.
Finish the rename started in #4809 to have a consistent naming.
`ExecutionPayloadHash` suggests hash over payload instead of block.
`BlockHash` is also the canonical name in engine API.
When using checkpoint sync, the initial block is missing in the DB.
Update the LC data collector initialization to account for that,
avoiding a spurious error message when it is incorrectly accessed:
```
ERR 2024-02-07 11:21:55.416+01:00 Block failed to load unexpectedly topics="chaindag_lc" bid=d30517a7:8257504 tail=8257504
```
Also fixes a regression from #5691 that resulted in similar messages
while importing the first few blocks after checkpoint sync.
Thanks to @arnetheduck for reporting this.
Full caches should not be used to mark blocks as unviable. The unviable
status is quite persistent and a block marked as such won't be processed
again once the cache empties. Problem originally introduced in #4808.
Changes here are more significant because of some good old tech debt in
block production which has grown quite hairy - the reduction in
exception handling at least provides some steps in the right direction.
The various major versions of `action/upload-artifact` and
`action/download-artifact` are not necessarily compatible.
Align all the uploads / downloads to `v3`.
`v4` exists but is not currently supported on GHES yet.
`eth1_chain` no longer logs with `topics` since #5768, making it hard
to filter messages from this module. Re-add the `topics`, and also fix
outdated `topics` in `el_manager` (formerly `*_monitor`).
To prevent accidental breakage of builds with non-standard developer
flags, add the `-d:has_deposit_root_checks` build to CI. This is only
a quick compilation check, and is only run on Linux.
- Synchronize order of `blobGasUsed` / `excessBlobGas` in test
- Reduce compiler warnings
- Upgrade github actions to v4
- v0.3.2
- re-add support for `fromBlock`, `toBlock`, `blockHash` in `eth_getLogs`
