ckb

This version is compatible with v0.25.0 and above. However, it is recommended to upgrade the node, since we will only release security patches based on the latest release.

See how to connect to various chains in Wiki.

This version has fixed several bugs, including the one that ckb complains that pool is full when sending conflicting transactions.

Downloads

* Windows support is experimental.

The .asc files are signatures. It is wise and more secure to check out for the files integrity.

Improvements

• Upgrade tentacle to 0.3.7 (@driftluo).

Bug Fixes

• #2532: Update statics for removing tx (@zhangsoledad)
• #2546: Resolve rocksdb cache size issue when using default.db-options (@quake)

This is an RC version to preview the changes in the next release.

RPC Deprecation

Pay attention that following RPC methods will be removed from v0.40.0:

• The method get_cells_by_lock_hash in the module Chain.
• The whole module Indexer.

The following methods will be disabled by default from v0.40.0 and will be removed from v0.41.0:

• The method get_cellbase_output_capacity_details in the module Chain.
• The method get_peers_state in the module Stats.
• The methods _compute_transaction_hash, _compute_script_hash and estimate_fee_rate in the module Experiment.

Config Changes

Because of deleted RPC methods, following keys must be deleted from the existing config file ckb.toml:

• Indexer is no longer a valid RPC module in [rpc] modules.
• The whole section [indexer] is removed.

* Windows support is experimental.

Features

• #2501: chore: remove deprecated RPC and add deprecated to some RPC.

  Resolve #2487

• #2297: Chain freezer (@zhangsoledad)

  Introduce chain freezer, Inspired by [Splitting the data directory] and [geth-v1-9-0]

  Now, separated database into two parts, recent block and ancient history. If your data directory is located on a magnetic disk, you can link db to an SSD drive to improve performance. If your data directory is on an SSD: you can link ancient to an HDD drive to save space.

  Freezer is disabled by default. It has some performance bottlenecks that we are fixing.

Breaking Changes

Database

⚠️ This new version will migrate the database on first launch. Please backup the data dir if you want to use old versions later.

⚠️ The migration takes about half an hour. The node denies all RPC requests during the migration.

Config file

There is a new config option db.options_file introduced in #2299. This option provides an options file to tune RocksDB for your workload and your system configuration. More details can be found in the official tuning guide. Remove or comment this option to use the default options file, which is the behavior in previous versions.

RPC

The RPC get_cells_by_lock_hash is deprecated and now it only returns errors (#2269).

There are 4 new RPC methods: ping_peers, get_transaction_proof, verify_transaction_proof, and clear_banned_addresses.

The subscribe RPC added a new topic new_transaction.

This version has some breaking changes in RPCs. The RPC error now uses different error codes and returns the detailed error information in the data field. (#2038)

There are also a bunch of new RPCs and new fields for existing RPCs, see the CHANGELOG for details.

This version also has migrated the database schema. It will run automatically when the new version starts the first time. (#2152)

Attention: The migration is not reversible. Please backup the data directory if you want to use old versions later.

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)

• #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.

• #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

ckb 0.35.0-pre (0c1a61c 2020-08-10)

This is an RC version to preview the changes in the next release.

This version has some breaking changes in RPCs. The RPC error now uses different error codes and returns the detailed error information in the data field. (#2038)

There are also a bunch of new RPCs and new fields for existing RPCs, see the CHANGELOG for details.

This version also has migrated the database schema. It will run automatically when the new version starts the first time. (#2152)

* Windows support is experimental.

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)
