- Move insufficient funds check from create_and_send_cpfp_tx to can_speedup - Centralize all speedup validation logic in can_speedup function - Add warnings and notifications for insufficient funds and missing funding - Replace all self.store.can_speedup() calls with self.can_speedup() - Remove duplicate validation logic from dispatch_transactions and process_active_speedups - Simplify perform_speedup to use can_speedup directly - Remove notify_funding_not_found helper method (inline in can_speedup)
This commit implements a major refactoring of the speedup transaction dispatch
mechanism, changing from immediate dispatch to a deferred queuing system that
preserves ordering and improves error handling.
Key changes:
1. Deferred Speedup Dispatch:
- Speedups are now created and marked as ToDispatch instead of being sent
immediately
- Dispatch happens in the next tick, preserving ordering guarantees
- This ensures speedups are dispatched sequentially, maintaining funding chain
dependencies
2. Transaction Storage in Speedup:
- Added tx: Option<Transaction> field to CoordinatedSpeedUpTransaction
- Speedup transactions are now stored with their speedup data
- Funding transactions use None (no transaction needed)
3. Method Refactoring:
- Renamed create_and_send_cpfp_tx -> create_cpfp_tx (creates and queues)
- Split dispatch_speedup into:
* dispatch_speedup: Marks speedup for dispatch (monitor + save)
* dispatch_speedup_tx: Actually sends transaction to network
- Renamed should_boost_speedup -> should_boost_last_speedup
4. Enhanced Error Handling:
- dispatch_speedup_tx validates transaction exists and tx_id matches
- Retryable errors (MempoolRejection/NetworkError) keep ToDispatch state
- Fatal errors mark speedup as Failed
- Proper state updates after successful dispatch (InMempool)
5. Improved Tick Flow:
- Process speedups first, then transactions, then boost operations
- This ensures speedups created in a tick are dispatched in the next tick
- Prevents same-tick dispatch and maintains ordering
6. Validation Improvements:
- can_speedup now checks unconfirmed transactions first
- Better separation of concerns in validation logic
- should_boost_last_speedup checks ToDispatch state before attempting boost
7. Context Handling:
- Speedup transactions now use their own context (CPFP/RBF/FUNDING)
- News filtering updated to exclude speedup-related contexts
This refactoring improves reliability by ensuring speedups are dispatched in
the correct order, handles errors more gracefully, and provides better
separation between creation and dispatch phases.
Adjust test timing to accommodate the new deferred speedup dispatch system where speedups are queued and dispatched in subsequent ticks. Changes: - reorg_test: Increase mine/tick iterations from 4 to 8 to allow sufficient time for speedup transactions to be dispatched and confirmed - speedup_chain_recompute_fee_test: Replace single mine/tick with loop of 4 iterations to ensure proper sequencing of speedup dispatch - utils/mod: Remove unused import (SubscriberInitExt)
- Export TransactionBlockchainStatus from bitvmx-transaction-monitor - Add From<TransactionBlockchainStatus> for TransactionState implementation - Remove TransactionStatusExt trait in favor of direct From impl - Update coordinator to use direct status mapping via .into() - Map NotFound status to ToDispatch instead of Failed - Simplify AlreadyKnown error handling in dispatch_txs
