The portal_*Offer call was changed in the specs to actually do
gossip. Make it no longer possible to test purely an offer with
one node. Add OfferReal call for now until spec potentially gets
adjusted.
Also Add some Node information logging for FindContent and Offer
to be able to better debug failures and interoperability.
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.

* Fix Portal Hive fails by correcting Portal history JSON RPC API
- Field naming in discv5_nodeInfo
- Call naming of portal_historyStore
- Other: some proc to func adjustements
* Provide index to reconstruct missing storage slots
why;
Pivots will be changed anymore once they are officially archived. The
account of the archived pivots are ready to be swapped into the active
pivot. This leaves open how to treat storage slots not fetched yet.
Solution: when mothballing, an `account->storage-root` index is
compiled that can be used when swapping in accounts.
* Implement swap-in from earlier pivots
details;
When most accounts are covered by the current and previous pivot
sessions, swapping inthe accounts and storage slots (i.e. registering
account ranges done) from earlier pivots takes place if there is a
common sub-trie.
* Throttle pivot change when healing state has bean reached
why:
There is a hope to complete the current pivot, so pivot update can be
throttled. This is achieved by setting another minimum block number
distance for the pivot headers. This feature is still experimental
- Switch from using Option to Opt which allows for smoother
usage with already existing Result types
- With all moved to Opt, make more use of valueOr to avoid
too many if else clause indentation and unstead have a more
clear error path at each step
- Remove dead code, char limits, style guide, etc.
- Replace getEncodedKeyForContent with ContentKey.init
and use ContentKey.init for each type
* Miscellaneous tweaks & fixes
details:
+ Catch `TransportError` exception in `legacy.nim` module
+ Fix self-calling wrapper `hexaryEnvelopeTouchedBy()`
* Update documentation, logging etc.
* Changed `checkNode` batch list `seq[Blob]` => `seq[NodeSpecs]`
why:
The `NodeSpecs` type as used here is a tuple `(partial-path,node-key)`.
When `checkNode` partial paths are collected, also the node key is
available so it should be registered and not repeatedly recovered from
the database.
* Add optional begin/end trace statement in snap scheduler
why:
Allows to trace invoked entity and scheduler state variables
* 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.
