Hi,
I'm syncing Gnosis on a Celeron N5100 to get familiar with the codebase.
In the process I managed to optimize some things from profiling.
Since I'm not yet on the project Discord, I decided to open this PR as a
suggestion. This pass all tests here and gave me a nice boost for that
platform, although I didn't have time to benchmark it yet.
* reuse VM Memory objects with sync.Pool. It starts with 4k as `evmone`
[code
suggested](0897edb001/lib/evmone/execution_state.hpp (L49))
as a good value.
* set32 simplification: mostly cosmetic
* sha256-simd: Celeron has SHA instructions. We should probably do the
same for torrent later, but this already helped as it is very CPU bound
on such a low end processor. Maybe that helps ARM as well.
Regarding https://github.com/ledgerwatch/erigon/issues/6260
added flag `--p2p.allowed-ports=<porta>,<portb>` to restrict which ports
to use for sentries for different protocol versions.
Default for this flag is `30303, 30304` (first port is inherited from
`--port` flag defaults.
If `--port` is changed and it's new value is not presented in allowed
port list, provided port will be allowed as well as list provided via
`--p2p.allowed-ports`
Port picking is straightforward, we create sentry gRPC server for
protocol over first allowed port that is not already taken.
If there are no allowed ports left, erigon exits with hint.
Previously "in-memory" MDBX instances for fork validation and mining
were created inside `os.TempDir()`. We should create them inside
Erigon's datadir so that the file permissions and the disk are the same
as for the main database.
Prerequisite: https://github.com/ledgerwatch/erigon-lib/pull/676.
* Add eth/67
* Listen to eth/66 on a separate port
* Fix compilation error
* Fix cfg66.ListenAddr
* Update erigon ports in README
* Expose port 30304 in docker
* P2pProtocolVersionFlag instead of second sentry
* Remove "66 by default" from usage
* Small comment
--nat stun is an automatic external IP detection alternative to manual --nat extip option.
It can be used both at home or on production servers without any extra setup.
It is fast (up to 5 ms) and more reliable than alternatives (as the request goes to the public internet).
This auto-detection is useful to run multiple instances of a service in cloud environments
where the node IPs are not known in advance.
The test fails sometimes on macOS CI with:
v5_udp_test.go:477: unexpected error: "RPC timeout"
Fixing by increasing the timeout from 120ms to 700ms,
and move the test to the integration suite, because it takes up to 1s now.
* TestTable_ReadRandomNodesGetAll: refactor to integration and examples
* TestTable_bumpNoDuplicates: refactor to integration and examples
* TestUDPv4_smallNetConvergence: speed up from 1.7s to 0.3s by applying the test config
* TestUPNP_DDWRT: move to integration tests
* TestFairMix: split in 2, do more iterations in integration tests
* TestDialSched: speed up from 1s to 0.2s by removing the unexpected dial check,
(keep the check during the integration tests)
* configure a 50 ms timeout for tests (like v4 tests)
* use in-memory DB (like v4 tests)
* TestUDPv5_callTimeoutReset: improve speed from 1.2s to 0.2s
* TestUDPv5_callTimeoutReset: reduce the likelihood of "RPC timeout"
* move lookup tests to the "integration" suite
* log details of unmatched packets and sends to non-existing nodes
* fix flaky TestUDPv5_findnodeHandling:
Table.nextRevalidateTime was random (from 0 to 10s).
Sometimes it triggered doRevalidate immediately, and it produced an unexpected ping.
Configure a high interval to not revalidate during the tests.
Time improved from 1.7s to 0.2s.
Test with:
go test ./p2p/discover -run TestUDPv5 -count 1
The test is flaky when the reply timeout is too low.
Increasing the timeout makes it slow.
Move the test to the integration suite.
Having a higher timeout is fine there.
The UDP test must be closed after the serveTestnet exits.
If it happens before, the serveTestnet encounters this error.
(it tries to emulate a packet receival after closing the transport)
FindNode triggers a Ping in ensureBond.
This causes an extra Sleep for "ping back".
Don't wait for this in tests.
Close v5 tests.
The requests may also timeout if a lot of them queue up in the udpTest.pipe,
and serveTestnet is slow to process them.
Increase replyTimeout a bit to prevent that.
* exchange RLPx Hello even when maxpeers limit is reached
* bump MaxPendingPeers to increase the default handshake queue
(and the likelyhood of Hello exchange)
The test was flaky, because of the "endpoint prediction".
The test starts 5 nodes one by one.
Node 0 is used as a bootstrap node for nodes 1-4.
When it is about to add, say, node 3, nodes 0 and 1 might already have had a chance to communicate,
and updateEndpoints() deletes the node 0 UDP port, because fallbackUDP port was not configured.
In this case node 3 would get a bootstrap node 0 without a port and lead to an error:
v5_udp_test.go:110: bad bootstrap node "enr:...": missing UDP port
The problem was reproducible by this command:
go test ./p2p/discover -run TestUDPv5_lookupE2E -count 500
* use semaphore instead of a chan struct{}
* move MaxPendingPeers default value to DefaultConfig.P2P
* log Error if Accept fails
* replace quit channel with context
The test was slow, because it was trying to find
predefined nodeIDs (lookupTestnet) by generating random keys
and trying to find their neighbours
until it hits all nodes of the lookupTestnet.
In addition each FindNode response was waited for 0.5 sec (respTimeout).
This could take up to 30 sec and fail the test suite.
A fake random key generator is now used during the test.
It issues the expected keys, and the lookup converges quickly.
The reply timeout is reduced for the test.
Now it normally takes less than.1 sec.
This changes the definitions of Ping and Pong, adding an optional field
for the sequence number. This field was previously encoded/decoded using
the "tail" struct tag, but using "optional" is much nicer.

Most places that used this method were cutting off the 1st byte.
Refactor this idea to a common place.
* better naming: MarshalPubkey matches existing UnmarshalPubkey
* "Std" suffix for the ANSI standard encoding without cut off
* docs
Problem:
QuerySeeds will poke 150 random entries in the whole node DB and ignore hitting "field" entries.
In a bootstrap scenario it might hit hundreds of :lastping :lastpong entries,
and very few true "node record" entries.
After running for 15 minutes I've got totalEntryCount=1508 nodeRecordCount=114 entries.
There's a 1/16 chance of hitting a "node record" entry.
It means finding just about 10 nodes of 114 total on average from 150 attempts.
Solution:
Split "node record" entries to a separate table such that QuerySeeds doesn't do idle cycle hits.
UpdateFindFails/UpdateLastPingReceived/UpdateLastPongReceived events
are causing bursty DB commits (100 per minute).
This optimization throttles the disk writes to happen at most once in a few seconds,
because this info doesn't need to be persisted immediately.
This helps on HDD drives.
Encode and hash logic was duplicated in multiple places.
* Move encoding to p2p/discover/v4wire
* Move hashing to p2p/enode/idscheme
* Change newRandomLookup to create a proper random key on a curve.
If --nat extip:1.2.3.4 option is specified, the port mapping logic
(AddMapping/DeleteMapping) does nothing.
This optimization avoids running a goroutine for doing nothing.
Extract private key setup from the global config setup to make it reusable.
Return errors instead of panicing.
* NodeKey() method is removed - it is unused.
* use "log" for struct fields
* use "logger" for function parameters and local vars
This is a compromise between:
1) using logger := log.New() to avoid aliasing (log := log.New())
2) and keeping it short when logging e.g.: srv.log.Info(...)
