a5986e8 refactor: Remove CAddressBookData::destdata (Ryan Ofsky)
5938ad0 wallet: Add DatabaseBatch::ErasePrefix method (Ryan Ofsky)

Pull request description:

  This is cleanup that doesn't change external behavior. Benefits of the cleanup are:

  - Removes awkward `StringMap` intermediate representation for wallet address metadata.
  - Simplifies `CWallet`, deals with used address and received request serialization in `walletdb.cpp` instead of higher level wallet code
  - Adds test coverage and documentation

  This PR doesn't change externally observable behavior. Internally, the only change in behavior is that `EraseDestData` deletes rows directly from the database because they are no longer stored in memory. This is more direct and efficient because it uses a single lookup and scan instead of multiple lookups.

  Motivation for this cleanup is making changes like bitcoin#18550, bitcoin#18192, bitcoin#13756 easier to reason about and less likely to result in unintended behavior and bugs

⚙️ CodeRabbit Configuration File

**: # CodeRabbit AI Review Instructions for Dash Backports

Your Role

You are reviewing Bitcoin Core backports to Dash Core. Your ONLY job is to validate that the Dash commit faithfully represents the original Bitcoin commit with minimal, necessary adaptations.

Critical Validation Rules

1. File Operations Must Match (AUTO-REJECT if violated)

  • If Bitcoin modifies an existing file → Dash MUST modify (not create new)
  • If Bitcoin creates a new file → Dash creates
  • If Bitcoin deletes a file → Dash deletes
  • Common failure: Bitcoin modifies keys.txt, Dash creates new file with 58 keys

2. Size Ratio Check (80-150% of Bitcoin)

  • Count functional lines changed (exclude comments/whitespace)
  • Dash changes should be 80-150% of Bitcoin's size
  • Red flag: 2-line Bitcoin fix becoming 150+ lines in Dash

3. No Scope Creep

  • Reject if you see: "TODO:", "FIXME:", "while we're here", "also fix"
  • No unrelated refactoring or style changes
  • Only Bitcoin's intended changes + minimal Dash adaptations

4. Bitcoin-Specific Code Detection

  • Auto-reject witness/segwit code: msg_wtxidrelay, MSG_WTX, witness imports
  • Auto-reject RBF (replace-by-fee) functionality
  • Note: PSBT is supported in Dash (don't flag)

5. Mandatory Adaptations Only

  • bitcoindash in strings/paths
  • BitcoinDash in user-facing text
  • Port numbers: 8332→9998 (RPC), 8333→9999 (P2P)
  • Hardcoded test values specific to Dash
  • No other changes unless absolutely required

6. Completeness Check

  • All files changed in Bitcoin must be present
  • Extra files need clear justification (Dash-specific compatibility)
  • Missing files = incomplete backport

Review Process

  1. First: Check file operations match exactly
  2. Second: Calculate size ratio
  3. Third: Scan for scope creep patterns
  4. Fourth: Detect Bitcoin-specific code
  5. Fifth: Verify all changes are minimal adaptations

Output Format

VALIDATION: [PASS/FAIL]

✅ Backport Verification - Issues Fixed

I found and fixed 5 issues:

  • Build failures on mac-build: Fixed by adding missing SafeDbt class definition
  • Build failures on win64-build: Fixed by adding missing SafeDbt class definition
  • Build failures on linux64_fuzz-build: Fixed by adding missing SafeDbt class definition
  • Build failures on linux64-build: Fixed by adding missing SafeDbt class definition
  • Build failures on arm-linux-build: Fixed by adding missing SafeDbt class definition

Original Bitcoin commit: 5325a61167
Fix commit pushed: ecffdd7e39
Reviewed commit hash: 2356a55572-verify-1753587992

Issue Details

The build failures were caused by a missing SafeDbt class definition in src/wallet/bdb.h. The Bitcoin backport accidentally removed this class definition from the header file, but the implementation in src/wallet/bdb.cpp still tried to use it in the ErasePrefix method, causing compilation errors across all platforms.

Fix Applied

Added the complete SafeDbt class definition back to the BerkeleyBatch class in bdb.h with all required methods:

  • Default constructor
  • Data constructor
  • Destructor
  • get_data() and get_size() methods
  • operator Dbt*() conversion

This fix preserves the Bitcoin intent while ensuring the code compiles properly in Dash.

🔇 Additional comments (33)
src/wallet/bdb.h (3)

173-190: LGTM - Necessary compilation fix

The SafeDbt class definition matches the fix described in the PR comments where this class was accidentally removed in the original backport, causing build failures across all platforms. The restoration includes all necessary methods: constructors, destructor, accessors, and conversion operator.


197-197: LGTM - Clean interface implementation

The ErasePrefix method override correctly implements the new database interface requirement for prefix-based key deletion.


225-225: LGTM - Simple accessor method

The txn() accessor method provides clean access to the active transaction pointer.

src/wallet/db.h (2)

94-94: LGTM - Clean interface addition

The pure virtual ErasePrefix method correctly extends the DatabaseBatch interface to support prefix-based key deletion across all database backends.


170-170: LGTM - Appropriate dummy implementation

The DummyBatch override correctly returns true as a no-op, consistent with other dummy method implementations in this class.

src/wallet/sqlite.h (1)

30-30: LGTM - Clean SQLite backend extension

The additions properly extend the SQLite batch interface with:

  • A prepared statement for efficient prefix deletion
  • A helper method for statement execution
  • The required ErasePrefix method override

This maintains consistency with the Berkeley DB implementation and follows good SQLite practices.

Also applies to: 33-33, 39-39

src/wallet/interfaces.cpp (1)

274-275: LGTM - Clean conditional logic

The modification correctly distinguishes between erasing (empty value) and setting receive requests, implementing the new wallet interface methods appropriately.

src/wallet/bdb.cpp (1)

819-840: LGTM - Well-implemented prefix erasure

The ErasePrefix implementation correctly:

  • Uses proper transaction management with TxnBegin/TxnCommit/TxnAbort
  • Employs cursor iteration with DB_SET_RANGE for efficient prefix seeking
  • Performs careful memory comparison to ensure prefix matching
  • Handles errors appropriately with cursor cleanup

The algorithm is sound and follows Berkeley DB best practices.

src/wallet/sqlite.cpp (5)

150-150: New SQL statement for prefix-based deletion added correctly.

The SQL query DELETE FROM main WHERE instr(key, ?) = 1 properly implements prefix-based deletion by checking if the key starts with the given prefix using SQLite's instr function.


407-407: Consistent statement cleanup for new prefix deletion statement.

The new m_delete_prefix_stmt is properly included in the statement finalization list in the Close() method, ensuring proper resource cleanup.


473-489: Well-designed helper method for statement execution.

The new ExecStatement method consolidates the common pattern of binding a blob parameter, executing the statement, and cleaning up. This reduces code duplication and improves maintainability.


491-494: EraseKey method correctly refactored to use helper.

The refactoring of EraseKey to use the new ExecStatement helper is clean and maintains the same functionality while reducing code duplication.


496-499: New ErasePrefix method implements database interface correctly.

The ErasePrefix method properly implements the new DatabaseBatch interface method using the prefix deletion SQL statement, providing consistent prefix-based key deletion functionality.

src/wallet/walletdb.h (2)

10-10: Include for script/standard.h added appropriately.

The new include is required for CTxDestination type used in the new address-specific methods.


228-231: New address-specific methods replace generic destdata interface.

The new methods provide a more type-safe and specific interface for wallet address data management:

  • WriteAddressPreviouslySpent for tracking spent addresses
  • WriteAddressReceiveRequest/EraseAddressReceiveRequest for receive request management
  • EraseAddressData for comprehensive address data cleanup

This represents a clear improvement over the previous generic destdata approach.

src/wallet/test/wallet_tests.cpp (3)

444-451: Database format array enables comprehensive cross-backend testing.

The DATABASE_FORMATS array properly conditionally includes available database formats, enabling the tests to run across all supported backends.


453-466: Well-designed helper function for database format-specific testing.

The TestLoadWallet helper function properly creates wallets with specific database formats and provides a clean interface for running test lambdas under wallet lock. This enables comprehensive testing across database backends.


468-501: Comprehensive test coverage for new address data functionality.

The rewritten LoadReceiveRequests test provides excellent coverage:

  • Tests previously spent flag functionality
  • Tests receive request writing, erasing, and persistence
  • Verifies data correctness across wallet reloads
  • Tests EraseAddressData cleanup functionality
  • Runs across all supported database formats

This thorough test coverage ensures the new address data management functionality works correctly across all database backends.

src/wallet/walletdb.cpp (4)

571-584: Clean refactoring of destdata handling.

The explicit handling of "used" and "rr" prefixed keys replaces the generic destdata approach with type-safe methods. This aligns perfectly with the PR objective to remove CAddressBookData::destdata and improves code clarity.


1106-1110: LGTM! Clean typed interface for address previously spent tracking.

The conditional write/erase logic based on the boolean parameter provides a clean API for managing address reuse tracking, replacing the generic destdata approach.


1112-1120: LGTM! Clean typed interfaces for receive request management.

These methods provide clear APIs for writing and erasing receive requests using the "rr" + id convention, replacing the generic destdata approach with type-safe methods.


1122-1127: LGTM! Efficient prefix-based address data cleanup.

The method correctly constructs the DESTDATA prefix for the address and uses the underlying ErasePrefix functionality to efficiently remove all associated data.

src/wallet/wallet.h (3)

224-240: Excellent refactoring to explicit typed members.

The replacement of the generic destdata map with explicit previously_spent boolean and receive_requests map significantly improves type safety and code clarity. The comprehensive documentation clearly explains the purpose of each member.


603-606: LGTM! Clean loading interfaces for new typed members.

These methods provide the necessary interface for loading the previously spent status and receive requests during wallet initialization, supporting the refactored data structure.


831-836: LGTM! Complete API for explicit address data management.

The methods provide clean interfaces for querying and managing the previously spent status and receive requests, completing the refactored address data management system.

src/wallet/wallet.cpp (8)

879-884: LGTM! Consistent refactoring from "used" to "previously spent".

The change from IsAddressUsed to IsAddressPreviouslySpent and SetAddressUsed to SetAddressPreviouslySpent is consistent with the overall refactoring described in the PR summary.


896-896: LGTM! Method call updated correctly.

The IsAddressUsed call has been properly updated to IsAddressPreviouslySpent.


903-903: LGTM! Consistent terminology update.

The PKHash variant also correctly uses IsAddressPreviouslySpent.


2281-2290: LGTM! Clear documentation of address data handling.

The added comments clearly explain why EraseAddressData should not be called for receiving addresses (to preserve the previously_spent value). The new EraseAddressData call properly removes all associated data for non-mine addresses.


2688-2700: LGTM! Proper implementation of typed address data.

The refactored SetAddressPreviouslySpent correctly:

  • Uses the new WriteAddressPreviouslySpent method for persistence
  • Directly sets the previously_spent field in address book data
  • Maintains the same logic flow as before

2702-2710: LGTM! Straightforward refactoring of load methods.

Both LoadAddressPreviouslySpent and LoadAddressReceiveRequest correctly populate the new typed fields in m_address_book.


2712-2716: LGTM! Clean implementation of status check.

IsAddressPreviouslySpent properly checks the previously_spent field with appropriate null-checking.


2718-2741: LGTM! Complete refactoring of receive request handling.

The receive request methods have been properly refactored to use the new typed data structure:

  • GetAddressReceiveRequests iterates over the typed receive_requests map
  • SetAddressReceiveRequest uses the new WriteAddressReceiveRequest method
  • New EraseAddressReceiveRequest provides deletion functionality
    All methods correctly manipulate the m_address_book entries directly.

- Simplify overly detailed comment in setAddressReceiveRequest method
- Remove editorial commentary about potential improvements
- Keep only essential information relevant to current functionality
