Features

• #2038 rpc: Re-organize RPC errors (@doitian)

  This is a breaking change: b:rpc

  This PR reworks on the RPC errors:

  • Use JSONRPC error code to differentiate different errors. Also prefix the error code in the message to be search engine friendly.
  • Make error message simple and easy to understand. The dump of the error is added as the data instead.
  • Avoid reusing the same error message for different reasons.

  Breaking Changes

  • The error object data field is always absent before, now it can be a string which contains the detailed error information.
  • The code in error object is always -3 for all the CKB internal errors, now it can have different values to differentiate different errors. Check the file rpc/src/error.rs.
  • The error messages have been updated to improve readability.

• #2049 rpc: Improve error messages from send transaction RPC (@doitian)

• #2178 rpc: Add generate_block RPC to IntegrationTest module (@quake)

  It allows user to generate block through RPC, it's a convenient feature for dApp integration test (like truncate RPC)

• #2188 rpc: Add sync state RPC (@driftluo)

  Wallet can fetch the best known block header the node gets from the P2P network.

• #2184 rpc: Tx_pool_info include tip hash (@keroro520)

• #2144 rpc: Add set_network_active RPC (@quake)

  Allows user to pause and restart p2p network message processing through RPC.

• #2190 rpc: Move add_node / remove_node RPC to Net module (@quake)

• #2196 rpc: Add more fields to RPC get_peers (@quake)

  Added connected_duration, last_ping_duration, protocols and sync_state to get_peers RPC.

• #2195 rpc: Add more fields to local_node_info RPC (@quake)

  Added active, connections and protocols fields to local_node_info.

• #2159: Load db options from a file; support configuring column families (@yangby-cryptape)

• #2175: Support multiple file loggers in ckb.toml (@yangby-cryptape)

• #2182: Take full control of main logger filter via RPC (@yangby-cryptape)

Bug Fixes

• #2158: Panic if db options is empty (@yangby-cryptape)

• #2157: The option of db path doesn't work (@yangby-cryptape)

• #2177: Fix the lenient logger filter parser (@yangby-cryptape)

• #2134: Update proposal table after chain reorg (@zhangsoledad)

  Previously, proposal-table update not considered in chain rollback, it's almost impossible to happen in hashrate-based chain. But can be triggered by truncate RPC.

• #2197: Should exit with error code when setup failed (@yangby-cryptape)

  Issue: if the config was malformed and an error was thrown in setup_app, the process wouldn't exit.

Improvements

• #2152: Change storage molecule table to struct (@quake)

  This is a breaking change: b:database

  Storage structs HeaderView, EpochExt and TransactionInfo are fixed size, we should use molecule struct instead of table, it reduces storage size and improves the performance a little bit.

• #2150: Don't query store twice in method chaining (@yangby-cryptape)

• #2151: Reduce times of querying header map (@yangby-cryptape)

• #2147: Don't cache all data of header map in memory during IBD (@yangby-cryptape)

• #2154: Split chain iter (@zhangsoledad)

• #2153: Decoupling migration from db (@zhangsoledad)

  Previously, migration coupling with DB, this sacrifice flexibility. In a case like this, opening a read-only DB will be trouble.
  This PR proposal split migration.

• #2163: Add HeaderProvider trait and split DataLoader to smaller trait (@quake)

• #1988: Use a new method to detect headers sync timeout (@yangby-cryptape)

  To avoid possible performance issues on headers synchronization.

• #2180: Add case description and some assertion for alert_propagation integration test (@chuijiaolianying)

• #2179: Refactor about integration service mining relate cases. (@chuijiaolianying)

• #2189: Add case description and update case assertions for consensus related cases. (@chuijiaolianying)

• #2204: Add some trait for integration cases (@chuijiaolianying)

• #2164: Improve script error (@doitian)

• #2168: Improve error when submitting block (@doitian)

• #2169: Small tx-pool refactoring (@zhangsoledad)

  • rename ContextualTransactionVerifier -> TimeRelativeTransactionVerifier
  • split NonContextualTransactionVerifier from TransactionVerifier
  • check syntactic correctness first before
  • refactory tx-pool rejection error
  • re-broadcast when duplicated tx submit
