Assets 4

This is a protocol upgrade release. All nodes should upgrade before 2018-07-19 14:00:00 UTC.

Note: in the previous release (2.0.180425) we fixed a serious bug.

  • If you're upgrading from 2.0.180425 to 2.0.180612, you don't need to do anything special;
  • if you're upgrading from a release earlier than 2.0.180425 to 2.0.180612, please check release notes of 2.0.180425 to see if you need to perform additional steps.

Consensus changes

API changes

  • extensions field of call_order_update_operation changed from an array to an object, which affects all related API's E.G. get_block, get_account_history, get_relative_account_history and etc. Due to this, old version of cli_wallet won't be compatible with new API nodes when that operation would occur in result.
  • [Issue #862, PR #872] Improved pagination of list_assets node API
  • [Issue #863, PR #871] Node get_ticker API now returns time stamp of latest block instead of server time
  • [Issue #811, PR #861] Added get_full_account command/API to cli_wallet

Other changes

  • [Issue #878, PR #927] Made number of I/O threads configurable (can be manual or auto)

  • [Issue #805, PR #840 / #919 / #937] Improved logging level and messages; added logging options about log-rotation

  • [Issue #837, PR #848 / #839] Added cli_wallet to Docker

BitShares Core Release 2.0.180425

This is a bugfix release.

In this release we fixed a bug in account history plugin, which may result in incorrect operation history IDs being stored under certain circumtances. Account history is mainly used by 3rd-party businesses for integration.

This bug doesn't affect consensus or chain security.

Who need to upgrade, and what to do

Businesses (E.G. exchanges, payment processors, gateways or merchants) who're running witness_node with track-account option, if rely on correctness of operation history object IDs (1.11.x) returned by witness_node to identify transactions, are likely affected.

Please:

  1. upgrade the node, and
  2. restart the node with --replay-blockchain parameter, and
  3. carefully check historical data which was retrieved from the old node and processed in the past, compare it to new data returned by upgraded node, deal with the differences if needed, and
  4. perhaps review business data process logic.

Please be aware that the 3rd step is important for businesses to avoid processing same transaction (E.G. a deposit) more than once. After restarted with --replay-blockchain, history object IDs may have changed. For example, before restart, get_relative_account_history [account_name] 0 1 0 may return an operation history ID 1.11.123456789 which indicates a deposit, but after restart, operation history ID of the same deposit may have changed to 1.11.123456700.

All earlier versions are affected.

Who are not affected

Here are some cases likely not affected by the bug. However, for your own safety, please make decision by your own.

  • The bug doesn't affect delayed_node, so data stored and returned by delayed_node is always correct. IDs stored in witness_node can be different than those stored in delayed_node. If a business only reads data from delayed_node, it's not affected.

    • However, if the business also reads data from witness_node, it can be affected.

  • Businesses that don't rely on correctness of 1.11.x IDs to identify transactions, for example those identify transactions by transaction IDs or signatures, are likely not affected, so don't need to upgrade.

  • Nodes that were not running with track-account option are not affected, so no need to upgrade.

    • Nodes running with default options are in this categary.
    • Public seed nodes, API nodes and witnesses should be in this categary.

  • Personal nodes that are not interested in history object IDs are probably affected, but usually don't need to upgrade.

More info about the bug

The bug was in account history plugin, if track-account option is used in a node, when forking occurs (E.G. due to network latency issues), the node may unintendedly skip some IDs. After that, incorrect IDs will be stored and then be returned when being queried. A restart with --replay-blockchain may correct IDs of existing/historical data, but doesn't prevent new incorrect IDs from being stored.

After upgraded and replayed, the node won't skip IDs, so will always store correct IDs.

Related issue and pull request: #585, #873.

This release contains several security fixes. All nodes please upgrade as soon as possible.

Note:

  • libcurl-dev is a dependency since release 2.0.171212. For Ubuntu, use this command to install it:
    • sudo apt-get install libcurl4-openssl-dev
  • The submodule remote URLs were changed in this release. To update an existing local repository, need to run additional git submodule sync and git submodule update commands:
git fetch origin
git checkout 2.0.180328
git submodule update --init --recursive # this command will fail
git submodule sync --recursive
git submodule update --init --recursive
