The node stopped pushing new mining job

We are running two nodes for the mining process, both node seems working smoothly, but we just noticed that one node was not pushing new mining job last night. So I killed this node and synced it again. At the very beginning after the node catched up the chain, it could push out job with no problem, but after sometime (within 1 hour I guess), no more job pushed from this node. The output of the node still seems 'OK', getting new block from main chain, just no mining job notifing the miner at all. The node version is 1.0.2. Both our two nodes are using the exact same startup config setting.

Contract accounts should be able to stake and vote and sponsor

It seems that the current implementation of the internal Staking contract does not support staking from contract accounts. As contract/multisign wallet exist in practice, we should allow these accounts to use the staking contract. -- It is okay to forbid them from using Admin and Sponsor contract though.

BTW, internal_contract/README.md is a quite old version where withdrawal fee is not removed yet.

Fullnode RPC and pub/sub need enhancement
Some local and test RPCs (e.g. txpool related RPCs) are very useful for scan and infuradevelopment, suggest fullnode to allow user to configure public/intranet access for those RPCs, just as what Ethereum did now.

Need some enhancements for current PRCs and pub/sub for infura development:

RPC: some data missed in the returned logs of RPC cfx_getTransactionReceipt.

RPC: better to provide a public or local API to return receipts for specified block or even epoch number, e.g. getBlockReceipts(blockHash), getEpochReceipts(epoch), it will significantly increase the performance of data sync.

Pub/sub: atomically push batch epochs to client when pivot chain switched, which is handled in a lock on fullnode. Thus, client could also atomically handle pivot chain switch.

Pub/sub: allow user to specify which epoch to subscribe, e.g. latest_mined, latest_state, latest_confirmed or latest_checkpoint.

RPC & Pub/sub: support to return 4 epoch numbers, including latest_mined, latest_state, latest_confirmed or latest_checkpoint.

$how to generate txs with transactiongen\src\lib.rs?$

how to generate txs with transactiongen\src\lib.rs?

我想要在本地链上运行conflux节点测试conflux可以达到的吞吐率，但是直接运行start.sh后，只能打印出产生的区块信息，没有任何交易被打包。所以我阅读了conflux-rust源码，发现transactiongen\src\lib.rs有交易生成代码。该文件中共有三个FIXME,我按照第一个FIXME提示，将其中的new改为了start,将返回值从self改成了Result。 impl TransactionGenerator { // FIXME: rename to start and return Result pub fn start( consensus: SharedConsensusGraph, txpool: SharedTransactionPool, sync: SharedSynchronizationService, secret_store: SharedSecretStore, ) -> Result 但是在编译时报告参数错误，需要两个返回值。 Compiling txgen v0.1.0 (F:\Senior01\DiplomaPro\Code\conflux-rust\transactiongen) error[E0107]: wrong number of type arguments: expected 2, found 1 --> transactiongen\src\lib.rs:89:10 | 89 | ) -> Result | ^^^^^^^^^^^^ expected 2 type arguments 我没有足够的时间将conflux-rust源码完整阅读，所以开发人员可以告诉我如何修改该文件以随机生成大量的交易，从而测试在A Decentralized Blockchain with High Throughput and Fast Confirmation提到的吞吐率吗？

OOM with default parameters on 16GB-memory linux machines.

The default parameters are meant to keep the system stably running with the claimed throughput. Currently, after running for about a week, the process will be killed because of system OOM killer or failure to allocate new memory.

We need to find out if it's because some significant memory usage is not counted or it's because we underestimate the memory usage in our cache-related calculation.

Full node may set wrong state root after syncing checkpoints.

The behavior is that a full node successfully syncs the headers and the checkpoint, and it enters CatchUpSyncBlockPhase, but all received blocks are marked partial invalid due to incorrect state root.

The log containing the root cause has been garbage collected, so we probably need to reproduce this on TestNet again for further investigation.

memory allocation of 503316480 bytes failed

一个新节点，上午开启full 模式在同步，但是下午 13：29 便出现 memory allocation of 503316480 bytes failed导致程序自动退出。

这个错误信息，来自控制台输出的日志。这个自动退出问题，使得我的节点一直没能完成同步，花了一个周末时间还是未成功同步到最新状态。

Fix double-lock in sync_manager.rs

There is a double-lock bug in fn request_now_from_peer: The first lock: https://github.com/Conflux-Chain/conflux-rust/blob/cc2c436a3bd76f62d196cff0d8845efbf1fa149d/core/src/light_protocol/handler/sync/common/sync_manager.rs#L291 Call insert_waiting: https://github.com/Conflux-Chain/conflux-rust/blob/cc2c436a3bd76f62d196cff0d8845efbf1fa149d/core/src/light_protocol/handler/sync/common/sync_manager.rs#L314 The second lock: https://github.com/Conflux-Chain/conflux-rust/blob/cc2c436a3bd76f62d196cff0d8845efbf1fa149d/core/src/light_protocol/handler/sync/common/sync_manager.rs#L146-L148

The fix is to add drop before calling insert_waiting.

Found the bug with my static detector lockbud.

v2.2.0(Nov 3, 2022)
This release introduces incompatible changes and must be upgraded before the block number 137740000 and PoS block number 360900.

RPC Improvements

Add filter RPCs in eSpace including eth_newFilter, eth_newBlockFilter, eth_newPendingTransactionFilter, eth_getFilterChanges, eth_getFilterLogs, eth_uninstallFilter. Note that you need to set poll_lifetime_in_seconds in the configuration to enable these RPCs.

Support finalized block tag and compatibility support for safe tag in eSpace RPCs.

Use a random 16 byte value for eth_filter id instead of an increasing integer.

Bug Fix

Fix the state availability check in RPCs when the full history states are available.

Fix a possible panic in PoS peer connection.

Fix an issue in the sigma protocol.

Fix a rare unexpected push delay in pubsub RPCs.

Fix the wrong unlock time setting for CIP99.

v2.1.0(Sep 26, 2022)
This release introduces a new hardfork. All nodes should be upgraded before the epoch number reaches 56800000 (estimated on Oct 18). Most CIPs will be enabled when the block number reaches 133800000 (estimated on Oct 25), and CIP-99 will be enabled when the PoS block number reaches 330000 (estimated on Oct 25).

Incompatible Changes

CIP-94 (https://github.com/Conflux-Chain/CIPs/blob/master/CIPs/cip-94.md): This CIP proposes to use on-chain DAO voting to decide and update reward parameters without hardfork.

CIP-97 (https://github.com/Conflux-Chain/CIPs/blob/master/CIPs/cip-97.md): This CIP proposes to remove account’s staking lists.

CIP-98 (https://github.com/Conflux-Chain/CIPs/blob/master/CIPs/cip-98.md): Fix a bug in BLOCKHASH opcode in eSpace.

CIP-99 (https://github.com/Conflux-Chain/CIPs/blob/master/CIPs/cip-99.md): Allow more not-voting terms before we force-retire a node, and make the unlock period of a retiring node shorter to allow the node to rejoin the PoS voting faster.

CIP105 (https://github.com/Conflux-Chain/CIPs/blob/master/CIPs/cip-105.md): PoS staking based minimal DAO vote count.

Configuration Improvement

Add configuration enable_single_mpt_storage to enable storing all history states. Set single_mpt_space = "evm" to only store eSpace states. Note that you'll need to resync an archive node to reconstruct all the history states.

Storage Improvement

Allow snapshots to be removed during recovery. This reduces the disk space requirement for full node sync or recovery.

RPC Improvement

Support eth_subscribe and eth_unsubscribe in eSpace RPCs.

Add a RPC method cfx_getParamsFromVote to return the currently used value of the voted parameters.

Return null for getting skipped transactions and receipts. Whether they will be returned was nondeterministic before, but now they are ensured to be null.

When querying logs, use LatestState instead of the to epoch number when the to epoch number is greater than LatestState.

Transaction Pool Improvement

Fix an issue that may fail to recycle packed but skipped transactions.

Add configuration enable_single_mpt_storage to enable storing all history states. Set single_mpt_space = "evm" to only store eSpace states. Note that you'll need to resync an archive node to reconstruct all the history states.

Storage Improvement

Allow snapshots to be removed during recovery. This reduces the disk space requirement for full node sync or recovery.

RPC Improvement

Support eth_subscribe and eth_unsubscribe in eSpace RPCs.

Add a RPC method cfx_getParamsFromVote to return the currently used value of the voted parameters.

Return null for getting skipped transactions and receipts. Whether they will be returned was nondeterministic before, but now they are ensured to be null.

v2.0.3(Jul 29, 2022)
Incompatible RPC Changes

cfx_getLogs and eth_getLogs will no longer support the parameters limit and offset. They are not efficient and can be replaced by setting the block/epoch range instead.

cfx_clientVersion will have include more information like web3_clientVersion in eSpace.

fromEpoch will default to "latest_state" in cfx_getLogs.

fromBlock will default to "latest" in eth_getLogs.

Improvements

Storage Improvements

Avoid re-executing blocks if possible. This will accelerate the recovery process and reduce the disk usage if the node is restarted fast.

Configuration Improvements

eSpace will be enabled for dev mode with a default configuration.

Enable persit_tx_index for Archive nodes automatically.

Bug Fixes

Fix a possible panic caused by inaccurate local timestamps.

Starting from v2.0.3, fromEpoch will default to "latest_state" in cfx_getLogs.

Starting from v2.0.3, fromBlock will default to "latest" in eth_getLogs.

RPC Improvements

Report error in cfx_getLogs and eth_getLogs if get_logs_filter_max_limit is configured but the query would return more logs. The previous behavior of cfx_getLogs was to silently truncate the result. The previous behavior of eth_getLogs was to raise an error when filter.limit is too low, regardless of how many logs the query would result in.

eth_gasPrice now estimate gas prices accurately instead of returning a fixed value.

Support phantom transactions and return correct fields in eSpace trace RPCs.

Add fields valid and createType for eSpace trace RPCs.

Add RPC rpc_methods to return all available methods and rpc_modules to return all RPC modules.

Add totalEspaceTokens in the response of cfx_getSupplyInfo.

Add local RPCs pos_start_voting, pos_stop_voting, and pos_voting_status. Check #2438 for details.

Accept requests with zero as sender in eth_call.

Accept unknown fields in eth_call.

Configuration Improvements

Allow PoS voting nodes to have running backups. #2438 includes an introduction.

Add config parameter get_logs_filter_max_block_number_range for limiting the maximum gap between from_block and to_block during Core space log filtering (cfx_getLogs). Note: eSpace blocks correspond to epochs in Core space, so the range in eth_getLogs can be limited using get_logs_filter_max_epoch_range.

Add config parameter min_phase_change_normal_peer_count to set the number of normal-phase peers needed for phase change. The default value is set to 3 to make it more robust.

Add environment variable CFX_POS_KEY_ENCRYPTION_PASSWORD to configure pos key encryption password. Check #2464 for details.

Set a proper max open files with ulimit in the default Linux/macOS start bash script.

Improve the client version output to include more information.

Transaction Pool Improvements

Allow pending transactions to be replaced unconditionally after 200000 epochs.

Bug Fixes

Fix an issue that phantom transactions may have the same hash. Now all phantom transactions have different hashes after this fix.

Create PoS log file directory if it does not exist.

Fix a panic issue when the node is started with stdout unavailable.

Fix an issue that an old transaction is not replaced according to a higher epoch_height.

Increase the request timeout upper bound to fix sync issues in normal cases.

pos_config-hydra.tgz(8.57 KB)
v2.0.0(Feb 14, 2022)
To node operators and miners:

Please upgrade your node before Epoch Number reaches 36935000 or Block Number reaches 92060600 (around 12:00 Feb.23rd, 2022(GMT+8)).

Please add pos_config (will be updated here after Feb.25th at 12:00) before Epoch Number reaches 37230000 (around Feb.28th 12:00).

If the binary cannot start, you can choose to compile the binary on your own platform or use the compatible version. Note that the compatible version has poorer performance and requires better hardware to run stably(possibly >4 cores).

The first time a v2.0 node starts, it will generate a PoS private key (stored in pos_config/key) and a password is required to encrypt it. The password is needed each time the node restarts. If the node will be registered as a PoS voter, please make sure the key file and the password are not leaked or deleted/forgotten.

v1.1.5(Jul 27, 2021)
Improvements

RPC Improvements

Fix incorrect responses of cfx_getBlockRewardInfo. If the node needs to serve this RPC, it needs to clear all data and resync the chain.

Simplify EVM revert reason in RPC responses. This may cause incompatible issues if the user was decoding the error messages manually.

Add new RPC cfx_getBlockByBlockNumber.

Add blockNumber to the returned JSON object in cfx_getBlockByHash, cfx_getBlockByEpochNumber, and cfx_getBlockByHashWithPivotAssumption.

Accept pivot hash in cfx_getEpochReceipts.

Raise error in cfx_getBlockByHashWithPivotAssumption if the provided block hash does not belong to the provided epoch.

Fix returnData format of CallResult.

Fix incorrect firstTxStatus response of cfx_getAccountPendingTransactions if start_nonce is provided.

Update cfx_getCode so that it returns an empty hex 0x if the account does not exist instead of raising an error.

Configuration Improvement

Add persist_block_number_index to persist block number indices. It allows responding to block-number-related RPC requests for old epochs.

Add storage_max_open_mpt_count to configure maximal number of opened MPT.
