Release Notes - Counterparty Core v10.2.0 (2024-06-11)

This is a large release that includes significant refactoring and redesigns of critical node components, including the CLI and logging subsystems, mempool processing, and API database connection management. It also includes numerous updates and extensions to the v2 API, plus new ZeroMQ support. Of course, a large number of bugs have been resolved as well.

Upgrading

The counterparty-server process now uses ZeroMQ to communicate with Bitcoin Core, in addition to the traditional RPC API. You must configure Bitcoin Core with:

[main]
zmqpubrawtx=tcp://0.0.0.0:9332
zmqpubhashtx=tcp://0.0.0.0:9332
zmqpubsequence=tcp://0.0.0.0:9332
zmqpubrawblock=tcp://0.0.0.0:9333
[test]
zmqpubrawtx=tcp://0.0.0.0:19332
zmqpubhashtx=tcp://0.0.0.0:19332
zmqpubsequence=tcp://0.0.0.0:19332
zmqpubrawblock=tcp://0.0.0.0:19333

Note: This update requires a reparse from Block 819250, which will proceed automatically upon initialization.

ChangeLog

Bugfixes

  • Fix circular imports
  • Return 404 errors for undefined API routes
  • Fix nested result value in the v1 API
  • Fix burned, earned, and btc_amount_normalized fields in API results
  • Do not cache non-cacheable v2 API routes (which could lead to a broken health check, in particular)
  • Fix the execution interval of the APIStatusPoller thread
  • Add Access-Control-Allow-Headers = * header to API v2 for CORS

Codebase

  • Refactor mempool management and block tracking—catching up is now done via RPC, and tracking via ZeroMQ
  • Introduce a new Rust module to fetch blocks from Bitcoin Core over RPC. Calls are now massively parallelized and buffered; block fetching no longer slows down block parsing
  • Refactor the backend module; separate calls to Bitcoin Core and AddrIndexRs into two different modules
  • Add the indexed tx_hash field to the messages table
  • Update rowtracer so that apsw returns a boolean instead of an integer for BOOL type fields
  • Delete the defunct implementation of rock-paper-scissors; introduce a replay_events() function to reconstruct the database from a hard-coded list of historical events
  • Enable parsing blocks while Bitcoin Core is still catching up
  • Optimize get_pending_dispensers() by adding the last_status_tx_source and close_block_index fields to the dispensers table; optimize is_dispensable() by caching a list of all dispenser addresses
  • Add the transaction_count field to the blocks table
  • Add the following new database indexes:
    • credits.calling_function
    • debits.action
    • transactions.source
    • credit.quantity
    • debit.quantity
    • balance.quantity
    • dispenser.give_quantity
    • order.get_quantity
    • order.give_quantity
    • dispense.dispense_quantity
  • Add the new EVENT log level
  • Disable the automatic SQLite ‘quick check’ for when the database has not been closed correctly. Display an error message when exiting and at the next restart.
  • Add retries to get_oldest_tx() on a Addrindexrs timeout

API

  • Introduce the following new routes:
    • /v2/assets/<asset>/dispenses
    • /v2/addresses/<address>/issuances
    • /v2/addresses/<address>/assets
    • /v2/addresses/<address>/transactions
    • /v2/addresses/<address>/dividends
    • /v2/addresses/<address>/orders
    • /v2/addresses/<address>/dispenses/sends
    • /v2/addresses/<address>/dispenses/receives
    • /v2/addresses/<address>/dispenses/sends/<asset>
    • /v2/addresses/<address>/dispenses/receives/<asset>
    • /v2/blocks/<block_hash>
    • /v2/blocks/last
    • /v2/transactions
    • /v2/transactions/<int:tx_index>/events
    • /v2/transactions/<tx_hash>/events
    • /v2/transactions/<int:tx_index>/events/<event>
    • /v2/transactions/<tx_hash>/events/<event>
    • /v2/transactions/<int:tx_index>
    • /v2/dividends
    • /v2/dividends/<dividend_hash>
    • /v2/dividends/<dividend_hash>/credits
    • /v2/mempool/transactions/<tx_hash>/events
    • /v2/events/<event>/count
    • /v2/bets
    • /v2/orders
    • /v2/dispensers
  • Introduce the cursor API parameter
  • Include next_cursor and result_count fields in all responses
  • Accept cursor/offset and limit arguments in all queries that return lists from the database (see the Pagination paragraph of the API Documentation)
  • Make the asset, assets, give_asset, and get_asset parameters case-insensitive
  • Add the named=true|false parameter to /v2/assets to returning only named / numeric assets
  • Publish events on the ZeroMQ Pub/Sub channel
  • Implement database connection pooling for both API v1 and v2
  • Enrich results containing block_index with block_time when verbose=true
  • Add an action filter for the */credits and */debits routes
  • Add an event_name filter for the */events routes
  • Specify issuer=None within XCP and BTC asset information
  • Exclude zero balances in the results of /v2/addresses/<address>/balances and zero quantities in the results of */credits and */debits
  • Add BTC sent to the DISPENSE event
  • Accept trailing slashes in routes
  • Include first_issuance_block_index and last_issuance_block_index in asset information
  • Add normalized quantities for the following fields:
    • fee_paid
    • fee_provided
    • fee_required
    • fee_required_remaining
    • fee_provided_remaining
    • fee_fraction_int
    • quantity_per_unit
    • btc_amount_normalized
    • burned
    • earned
    • dispense_quantity
  • Return asset info for dispenses
  • Add confirmation_target argument for compose endpoints

CLI

  • Use -v for the DEBUG level, -vv for the EVENT level, and -vvv for the TRACE level (it is also possible to repeat the --verbose flag)
  • Clean up and refactor CLI outputs for all commands
  • Clean up log messages and add numerous additional logging statements
