This fixes an issue where the mumbai testnet node struggle to find
peers. Before this fix in general test peer numbers are typically around
20 in total between eth66, eth67 and eth68. For new peers some can
struggle to find even a single peer after days of operation.
These are the numbers after 12 hours or running on a node which
previously could not find any peers: eth66=13, eth67=76, eth68=91.
The root cause of this issue is the following:
- A significant number of mumbai peers around the boot node return
network ids which are different from those currently available in the
DHT
- The available nodes are all consequently busy and return 'too many
peers' for long periods
These issues case a significant number of discovery timeouts, some of
the queries will never receive a response.
This causes the discovery read loop to enter a channel deadlock - which
means that no responses are processed, nor timeouts fired. This causes
the discovery process in the node to stop. From then on it just
re-requests handshakes from a relatively small number of peers.
This check in fixes this situation with the following changes:
- Remove the deadlock by running the timer in a separate go-routine so
it can run independently of the main request processing.
- Allow the discovery process matcher to match on port if no id match
can be established on initial ping. This allows subsequent node
validation to proceed and if the node proves to be valid via the
remainder of the look-up and handshake process it us used as a valid
peer.
- Completely unsolicited responses, i.e. those which come from a
completely unknown ip:port combination continue to be ignored.
-
Reason:
- produce and seed snapshots earlier on chain tip. reduce depnedency on
"good peers with history" at p2p-network.
Some networks have no much archive peers, also ConsensusLayer clients
are not-good(not-incentivised) at serving history.
- avoiding having too much files:
more files(shards) - means "more metadata", "more lookups for
non-indexed queries", "more dictionaries", "more bittorrent
connections", ...
less files - means small files will be removed after merge (no peers for
this files).
ToDo:
[x] Recent 500K - merge up to 100K
[x] Older than 500K - merge up to 500K
[x] Start seeding 100k files
[x] Stop seeding 100k files after merge (right before delete)
In next PR:
[] Old version of Erigon must be able download recent hashes. To achieve
it - at first start erigon will download preverified hashes .toml from
s3 - if it's newer that what we have (build-in) - use it.
* fix "genesis hash does not match" when dev nodes connect
The "dev" nodes need to have the same --miner.etherbase in order to
generate the same genesis ExtraData by DeveloperGenesisBlock(). Override
DevnetEtherbase global var that's used if --miner.etherbase is not
passed. (for NonBlockProducer case)
* fix missing private key for the hardcoded DevnetEtherbase
Fixes panic if SigKey is not found. Bor non-producers will use a default
`DevnetEtherbase` while Dev nodes modify it. Save hardcoded
DevnetEtherbase/DevnetSignPrivateKey into accounts so that SigKey can
recover it.
* refactor devnet.node to contain Node config
This avoids interface{} type casts and fixes an error with
Heimdall.validatorSet == nil
* add connection retries to rpcCall and Subscribe of requestGenerator
Fixes "connection refused" errors due to node not ready to handle early
RPC requests.
* fix deadlock in Heimdall.NodeStarted
* fix GetBlockByNumber
Fixes "cannot unmarshal string into Go struct field body.transactions of
type jsonrpc.RPCTransaction"
* demote "no of blocks on childchain is less than confirmations
required" to Info (#8626)
* demote "mismatched pending subpool size" to Debug (#8615)
* revert wiggle testing code
new flag examples.

## Description
Add the possibility to change the RPC address used in `devnet` without
requiring a rebuild.
## Test
- [x] `make devnet`
- [x] `./build/bin/devnet --datadir tmp`
- [x] `./build/bin/devnet --datadir tmp --rpc.host localhost --rpc.port
8546`
This PR removes the empty headers check when responding to
`GetBlockHeaders` p2p request. Currently, as we return from the
function, the requests on the caller's end gets timed out causing peer
drop. This will prevent that from happening by sending empty header list
which will be of no use but still helps in maintaining the peer
connection.
With this change, those running erigon 2.48 with
`--sentry.drop-useless-peers` will drop peers as they consider receiving
empty headers a harsh move which is fine.
We have also discovered that if we don't remove this check maintaining
connectivity to Bor is not maintained. This is significant as Erigon
becomes a minority validator, as bor chain stability (reducing forks) is
dependent upon good validator connectivity.
Fixes and issue with Polygon validators where locally mined blocks are
broadcast with invalid header hashes because the NewBlock message
constructor was removing the ReceiptHash which contributed to the header
hash.
The results in the bor header validation code not being able to
correctly identify the signer of the header - so header validation
fails.
This also likely fixes part of the bogon-block issue which was
identified by the polygon team.
This fixes 2 related issues:
* Now that the bor consensus engine is required for queries it can't be
created based on the pretense of a db directory, but must be based on
chain config read from the db. Using the DB presence causes Bor to get
instantiated for non bor chains which breaks.
* At the moment eth_calls on a remote daemon don't check Bor headers
prior to calling the EVM code as it was just using a fake ETHash
instance - which performs ETH header validation only.
The current version is mostly working but needs adapting to perform lazy
initialization of the engine.
This introduces _experimental_ block execution run by embedded Silkworm
API library:
- new command-line option `silkworm.path` to enable the feature by
specifying the path to the Silkworm library
- the Silkworm API shared library is dynamically loaded on-demand
- currently requires to build Silkworm library on the target machine
- available only on Linux at the moment: macOS has issue with [stack
size](https://github.com/golang/go/issues/28024) and Windows would
require [TDM-GCC-64](https://jmeubank.github.io/tdm-gcc/), both need
dedicated effort for an assessment
Whitelisting calculation of the roothash should not be dependent on the
bor api running. This will not always be the case, for example when
erigon is configured with a separate rpc deamon.
To fix this the calculation has been moved to Bor.
Additionally the redundant Bor API code has been removed as this is not
called by any code and the functionality looks to have migrated to the
turbo/jsonrpc package.
Fixes for label discrepancies in collector for summaries etc which have
a template which includes a quantile.
Initial native Prometheus client implementation of metrics - which is
currently turned off except for local testing and interface exports.
Closes#8078
This change is primarily intended to support go 1.21, but as a
side-effect requires updating libp2p, which in turn triggers an update
of golang.org/x/exp which creates quite a bit of (simple) churn in the
slice sorting.
This change introduces a new `cmp.Compare` function which can be used to
return an integer satisfying the compare interface for slice sorting.
In order to continue to support mplex for libp2p, the change references
github.com/libp2p/go-libp2p-mplex instead. Please see the PR at
https://github.com/libp2p/go-libp2p/pull/2498 for the official usptream
comment that indicates official support for mplex being moved to this
location.

This is a fix for at least one cause of this isssue:
https://github.com/ledgerwatch/erigon/issues/8212.
It happens after the end of the snapshot load, because the snapshot
processing which was introduced a couple of month ago does not deal with
validation of the headers at the start of the start of the chain.
I have also added a fix to the persistence so that the last snapshot is
recorded so that subsequent runs are not forced to process the whole
snapshot run from start.
The relationship between this an memory usage is that the fact that
headers are not processed leads to a queue of pending headers with size
of around 5GB. I have not changed any header parameters - so likely a
prolonged stop to header processing will result in a similar level of
memory growth.
Code to support react based UI for diagnostics:
* pprof, prometheus and diagnistics rationalized to use a single router
(i.e. they can all run in the same port)
* support_cmd updated to support node routing (was only first node)
* Multi content support in router tunnel (application/octet-stream &
appliaction/json)
* Routing requests changed from using http forms to rest + query params
* REST query requests can now be made against erigon base port and
diagnostics with the same url format/params

Some peer-review changes from the last related PR.
Addition of a flag for BlobSlots - for max allowed blobs per account in
txpool.
Use BlobFee from the block to validate txs in the pool.

This is the second part of the bor milestone release it contains the
following changes:
* Initialize services
* This is a change from the initial pull request I have moved all of the
initialization to the bor engine. To facilitate this I have just passed
in the heimdall client interface, rather than the whole engine
* Stage processing
* This is also a change from the original PR - the code is contained in
the bor heimdall stage rather than in headers - the effect should be the
same, but this needs testing
