At `turbo/jsonrpc/bor_snapshot.go:239` creates read only transaction and
acquire semaphore but does not rollback or commit transaction and
unrelease semaphore lock. Over time, this will result in the locking all
of semaphore resources. Any other resources can't acquire semaphore.
I added defer function to rollback transaction to release semaphore.
rlp2 is a package that aims to replace the existing erigon-lib/rlp
package and the erigon/common/rlp
it is called rlp2 for now because it requires breaking changes to
erigon-lib/rlp and i do not have the time right now to test all current
uses of such functions
however, the encoder/decoder characteristics of rlp2 might be desirable
for caplin, and also for execution layer parsing blob txns, so im
putting it in a folder called rlp2 (note that it exports package rlp for
easier switching later)
importantly, rlp2 is designed for single-pass decoding with the ability
to skip elements one does not care about. it also is zero alloc.
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.

also adds support for h2c to the http handler - http2 protocol without tls.
read transaction was opened before stream.Recv(), but stream.Recv() is
blocking infinity loop. so, this read transaction never rollback -
causing unlimited db grow.

* call getEnode before NodeStarted to make sure it is ready for RPC
calls
* fix connection error detection on macOS
* use a non-default p2p port to avoid conflicts
* disable bor milestones on local heimdall
* generate node keys for static peers config
Newly introduced `t.logGaps` was being set to `nil` and still accessed
within `clearFailedLogs`. This PR changes the ordering, moving the nil
setting to `CaptureTxEnd`.
Historically we had several times when:
- erigon downloaded new version of .seg file
- or didn't finish download and start indexing
this was a "quick-fix protection" against this cases
but now we have other protections for this cases
let's try to remove this one - because it's not compatible with "copy
datadir" and "restore datadir from backup" scenarios
