Trinity is moving fast. Read up on all the latest improvements.
Trinity 0.1.0-alpha.35 (2020-03-03)¶
We now “pivot” Beam Sync if we fall too many blocks behind. When a naive (non-pivoting) Beam Sync falls too far behind the tip of the chain, it can get “stuck” because the trie data is no longer available from peers. (#908)
Add support for networks that run under Clique consensus. Add support for syncing the Görli network via –goerli flag. (#1196)
Improve error message for when the parameters to JSON-RPC calls are invalid
Improve error message for
eth_submitHashrateAPIs which Trinity does not support as it generally does not support mining operations.
eth_coinbaseto also return errors instead of default values. (#1475)
admin_nodeInfoJSON-RPC endpoint (#1503)
Add support for Etherscan API keys to continue support for the
--beam-from-checkpoint eth://block/byetherscan/latestflag now that Etherscan has made API keys mandatory. API keys need to be exposed via the
TRINITY_ETHERSCAN_API_KEYenvironment variable. (#1565)
p2p.abc.MultiplexerAPI.closemethods are now coroutines to allow
p2p.abc.TransportAPI.close()to drain the underlying
StreamWriterbefore closing it, ensuring that any pending messages are written over the socket before closing it. (#1417)
- Ensure validation errors in components are properly handled during bootstrap. (#1486)
- Fix broken API docs on https://trinity-client.readthedocs.io/en/latest/api/ (#1510)
PeerConnectionLostwas escaping during a
highest_td_peercall, and crashing whatever called it. The exception is now caught. (#1524)
- Catch a variety of uncaught exceptions:
CorruptTransport. Also, prevent AttributeError when printing a
p2p.kademlia.Nodethat has no address. (#1545)
- Catch a
PeerConnectionLostraised when: disconnecting from a peer for sending a malformed message, and another one when finding the fastest peer. Reject handshake attempts when the IP address is unknown. Catch a
CorruptTransport, raised during multiplex. (#1548)
- Exit a bit more quickly from Beam Sync, by cancelling any hanging requests for state data. This
prevents a 5 second wait and timeout in the
Trinity 0.1.0-alpha.34 (2019-12-23)¶
Full rework of
ComponentAPIs. CLI validation is now done during application initialization. Component lifecycle is well defined and simpler to implement. (#1328)
Add support for eth_getTransactionReceipt JSON-RPC API
AsyncioIsolatedComponentno longer uses the standard libary
multiprocessingfor process isolation, in favor of using the more async friendly
web3module changed from v4 to v5, including in the console. (#1383)
End JSON-RPC responses with n to support dopple. (#1388)
Upgrade Py-EVM and add support for Muir Glacier fork (#1409)
ComponentAPIs to support concurrent starting and stopping. (#1328)
Trinity 0.1.0-alpha.33 (2019-12-12)¶
Internal Changes - for Trinity Contributors¶
Fix flaky interactive web3 console test
Due to the way components cross connect to each other, not all logs of that startup routine are happening deterministically. We were waiting on a log that would sometimes never show up for all valid reason. This test is now based on a log that is guaranteed to show up unless a serious bug happened. (#1382)
Trinity 0.1.0-alpha.32 (2019-12-09)¶
Upgrade py-evm to v0.3.0-alpha.10, for critical Istanbul bugfix, related to net gas metering. (#1893)
Only allow a single connection per peer, even if an outgoing and incoming handshake are initiated simultaneously. Bonus: squashed UnknownAPI log when talking to a peer that is disconnecting. (#1352)
Ensure ThreadPoolExecutor in beam importer is set up with contextmanager
Without contextmanager one needs to manually call shutdown on the executor which we weren’t doing either. This change may fix some warnings during shutdown of the client. (#1371)
- Speed up the TxPool shutdown a bit: it had hanging tasks that we were waiting 5s to force-close. (#1356)
Trinity 0.1.0-alpha.31 (2019-12-04)¶
- Upgrade py-evm to v0.3.0-alpha.9, which includes consensus-sensitive Istanbul fix. See the py-evm release notes (#1343)
- Add export and import command that lets one export blocks to a file or import blocks from a file. (#1266)
- Properly handle Ropsten and Goerli when using –beam-from-checkpoint eth://block/byetherscan/latest to resolve a checkpoint. Also, propagate a proper error to the user in case the syntax is used for an unsupported networḱ. (#1269)
- Automatically rotate logfiles across runs (#1294)
- Add support for eth_getTransactionByHash JSON-RPC API (#1329)
- When resuming beam sync, prefer to pick up from the canonical tip, if it’s not too far behind. (#1349)
Internal Changes - for Trinity Contributors¶
Trinity 0.1.0-alpha.30 (2019-11-13)¶
Trinity 0.1.0-alpha.29 (2019-09-30)¶
- Document how to install, run and develop with the Trinity DappNode package. (#1082)
Internal Changes - for Trinity Contributors¶
- Add a
make create-dappnode-imagecommand to expose Trinity as a DappNode package. The package can be found as
Pluginsare now called
Components. We’ve found
Componentsto be a better term for the provided functionality, especially since it is less loaded with the assumption of being something that optionally extends functionality when in reality Trinity’s core functionality is built out of
ConnectionAPI.get_receipt_by_type(receipt_type: Type[ReceiptAPI])API (#1148)
ConnectionAPInow has a mirrored version of
Trinity 0.1.0-alpha.28 (2019-09-12)¶
Remove Trinity specific subclass of the
lahjaendpoint in favor of using the core
EndpointAPIeverywhere. The previous functionality from the
TrinityEventBusEndpointis now handled by a special service designed to manage the endpoint lifecycle. (#672)
Allow trinity db-shell to inspect the beacon node (#809)
NewBlockEventon the event bus. (#822)
p2p.peer.receive_handshaketo encapsulate the logic for handling incoming connections. (#828)
p2p.p2p_proto.P2PProtocolclass now requires that handshake parameters be passed into the
send_handshakemethod. These parameters are now part of the
Add a new
p2p.tools.factories.TransportPairFactoryfor generating directly connected
p2p.multiplexer.Multiplexerfor combining the commands from different devp2p sub-protocols into a single network write stream, and split the incoming network stream into individually retrievable sub-protocol commands. (#835)
p2p.protocol.get_cmd_offsetshelper function for computing the command id offsets for devp2p protocols (#836)
BasePeerto handle the incoming message stream. (#847)
Add factories for creating devp2p protocols and commands for testing. (#850)
Beam Sync: parallel execution of blocks. When connected to a peer on a local network, can now keep up with mainnet (assuming a beefy machine). Also added beam stats in the logs. (#855)
multiprocessingbased database access with a custom implementation that increases database access performance by 1.5-2x (#859)
p2p.handshakeAPI. This provides a generic interface for performing proper DevP2p handshakes using multiple sub-protocols without needing involvement of the
Use the new
p2p.handshakeAPIs in the
p2p.peer.BasePeerhandshake logic. (#887)
If Trinity is beam syncing and a call to eth_getBalance requests data which is not in the local database, Trinity asks for the data over the network. (#894)
Speculative Execution in Beam Sync: split block transactions to run them in parallel, for speedup. (#899)
Allow beam sync to start from a trusted checkpoint. Specify a checkpoint via CLI parameter such as:
When given, beam sync will use this as a checkpoint to avoid having to download the entire chain of headers first. (#921)
Expose the force-beam-block-number config as a command line parameter. The config is useful for testing to force beam sync to activate on a given block number. (#923)
p2p.peer.BasePeerContextproperties and use for handshake. (#931)
If eth_getCode is called during beam sync but the requested data is not available locally trinity will attempt to fetch the requested data from remote peers. (#944)
Beam Sync: start backfilling data, especially as a way to gather performance data about peers, and improve the performance of beam sync importing. (#951)
p2p.service.run_servicewhich implements a context manager API for running a
p2p.connection.Connectionservice which actively manages the
p2p.multiplexer.Multiplexerexposing an API for registering handler callbacks for individuall protocol commands or entire protocols, as well as access to general metadata about the p2p connection. (#956)
If eth_getStorageAt is called during beam sync but the requested data is not available locally trinity will attempt to fetch the requested data from remote peers. (#957)
ConnectionAPIfor underlying protocol interactions. (#962)
Allow Trinity to automatically resolve a checkpoint through the etherscan API using this syntax:
Fetch missing data from remote peers, if requested over json-rpc during beam sync. Requests for data at an old block will fail; remote peers probably don’t have it. (#975)
MiningChainon the db-shell REPL to allow creating blocks on a REPL (#977)
ConnectionAPI.get_p2p_receiptfor fetching the
HandshakeReceiptfor the base
p2p.protocol.Protocol.supports_commandis now a
HandlerSubscriptionAPInow supports a context manager interface, removing/cancelling the subscription when the context exits (#989)
Handler functions for

Connectioninstance as the first argument. (#990)
p2p.session.Sessionwhich is now used in place of the
remoteto identify peers in the peer pool. (#1054)
HTTPServerfor JSON-RPC over HTTP APIs. (#1078)
Make beam the default sync strategy and remove fast sync. (#1084)
Detect if a checkpoint is too close to the tip and delay sync until we have reached a minimum distance to the tip. (#1107)
Proper cancellation of subtasks upon cancellation of
The recently introduced fix that ensures we do not run multiple concurrent handshakes to the same peer accidentially introduced a (rarely exposed) memory leak. This fix introduces a
ResourceLockand refactores the code to use it to also fix the previously introduced memory leak. (#811)
Fix issue where test state was leaking between tests in
Beam Sync: Serve node data requests in parallel, instead of series (#857)
DEBUG2logs always being shown irrespective of log level. (#860)
Beam Sync stats: Count the extra single node that is sometimes required when downloading the nodes needed to look up an account or storage. (Usually because of a trie reorg) (#877)
Fixes issue with Trinity not shutting down when issues a
BaseProxyPeerto properly represent the
Add missing field from to the response of RPC calls eth_getTransactionByBlockHashAndIndex and eth_getTransactionByBlockNumberAndIndex. (#889)
--profileparameter takes profiles of every process (#891)
Fix JSON-RPC call eth_getBalance(address, block_number) to return balance at the requested block_number. Earlier it would always return balance at block(0). (#900)

TimeoutErrorexceptions that can occur while multiplexing the devp2p connection (#916)
Fix type hints so that
max_headersis recognized as keyword argument to

PeerConnectionLostexception that bubbles from multiplexer.
Connectionis now responsible for calling
Multiplexer.closeon shutdown. Detect a closed connection during handshake. (#992)
P2PProtocol.send_disconnectto accept enum values from
Instead of the
ThreadPoolExecutorto normalize expensive messages. This fixes a bug where Trinity would leave idle processes from the
ProcessPoolExecutorbehind every time it shuts down after a sync.
Performance wise, both methods should be roughly compareable and since many task have already been moved to their own managed processes over time, using a
ThreadPoolExecutorstrikes as a simple solution to fix that bug. (#1004)
Fix a bug where trying to start beam sync from a checkpoint would throw an error due to an uninitialized var if a request to a peer would raise an error while we are trying to resolve a header from it. (#1005)
TrioService.run_taskto ensure that when a background task throws an unhandled exception that it causes full service cancellation and that the exception is propagated. (#1040)
Fix issue where Trinity does not recognize and disconnect from ETC peers when it is being used as an ETH client (#1050)
MalformedMessagerising out of the
Ensure discovery V4 handles invalid command ids gracefully (#1063)
Fix issue where attempts to establish new peer connections would halt shortly after startup due to missing timeout when attempting to dial a peer. (#1069)
An exception while serving peer requests would crash out the peer pool event server. Now it doesn’t crash, but logs a big red error (and catches innocuous exceptions, early on). (#1074)
An occasional warning “ValidationError: Duplicate tasks detected” was crashing the node. It’s recoverable, so log it, but don’t crash. (#1083)
Fix warning on ethstats.net due to incorrectly reported API version number. (#1094)
Fix warning caused by inappropriate call to
- Immediately insert Beam Sync nodes that are “predicted” (soon to be used during parallel execution) This saves a round trip on live execution, when parallel execution already downloaded a node. Also, more aggressively make predictive requests if no urgent requests are waiting in the queue. (#877)
- Previously, we gave up on predicted nodes that were not returned by a peer. Now we retry them, which helps make sure we aren’t missing any nodes at block import time. (#932)
- During Beam Sync previews, be sure to collect the nodes required to generate the new state root, rather than wait until it’s time to import the block. (#933)
Deprecations and Removals¶
