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 --- This PR is a rebased copy of bitcoin#18608. For some reason that PR is locked and couldn't be reopened or commented on. This PR is an alternative to bitcoin#27215 with differences described in bitcoin#27215 (review) ACKs for top commit: achow101: ACK a5986e8 furszy: Code ACK a5986e8 Tree-SHA512: 6bd3e402f1f60263fbd433760bdc29d04175ddaf8307207c4a67d59f6cffa732e176ba57886e02926f7a1615dce0ed9cda36c8cbc6430aa8e5b56934c23f3fe7
WalkthroughThis change refactors wallet address book data management by introducing explicit handling for "previously spent" addresses and receive requests, replacing the prior generic destination data map. It adds new methods for prefix-based key erasure in database backends, updates the wallet interface and data structures, and overhauls related tests for comprehensive coverage across database formats.

**: # CodeRabbit AI Review Instructions for Dash BackportsYour 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
bitcoin→dashin strings/pathsBitcoin→Dashin 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
- First: Check file operations match exactly
- Second: Calculate size ratio
- Third: Scan for scope creep patterns
- Fourth: Detect Bitcoin-specific code
- Fifth: Verify all changes are minimal adaptations

🔇 Additional comments (33)
src/wallet/bdb.h (3)
173-190: LGTM - Necessary compilation fixThe 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 implementationThe ErasePrefix method override correctly implements the new database interface requirement for prefix-based key deletion.
225-225: LGTM - Simple accessor methodThe txn() accessor method provides clean access to the active transaction pointer.
src/wallet/db.h (2)
94-94: LGTM - Clean interface additionThe pure virtual ErasePrefix method correctly extends the DatabaseBatch interface to support prefix-based key deletion across all database backends.
170-170: LGTM - Appropriate dummy implementationThe 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 extensionThe 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 logicThe 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 erasureThe 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, ?) = 1properly implements prefix-based deletion by checking if the key starts with the given prefix using SQLite'sinstrfunction.
407-407: Consistent statement cleanup for new prefix deletion statement.The new
m_delete_prefix_stmtis properly included in the statement finalization list in theClose()method, ensuring proper resource cleanup.
473-489: Well-designed helper method for statement execution.The new
ExecStatementmethod 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
EraseKeyto use the newExecStatementhelper is clean and maintains the same functionality while reducing code duplication.
496-499: New ErasePrefix method implements database interface correctly.The
ErasePrefixmethod properly implements the newDatabaseBatchinterface 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
CTxDestinationtype 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:
WriteAddressPreviouslySpentfor tracking spent addressesWriteAddressReceiveRequest/EraseAddressReceiveRequestfor receive request managementEraseAddressDatafor comprehensive address data cleanupThis 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_FORMATSarray 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
TestLoadWallethelper 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
LoadReceiveRequeststest provides excellent coverage:
- Tests previously spent flag functionality
- Tests receive request writing, erasing, and persistence
- Verifies data correctness across wallet reloads
- Tests
EraseAddressDatacleanup 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::destdataand 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_spentboolean andreceive_requestsmap 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
IsAddressUsedtoIsAddressPreviouslySpentandSetAddressUsedtoSetAddressPreviouslySpentis consistent with the overall refactoring described in the PR summary.
896-896: LGTM! Method call updated correctly.The
IsAddressUsedcall has been properly updated toIsAddressPreviouslySpent.
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
EraseAddressDatashould not be called for receiving addresses (to preserve thepreviously_spentvalue). The newEraseAddressDatacall properly removes all associated data for non-mine addresses.
2688-2700: LGTM! Proper implementation of typed address data.The refactored
SetAddressPreviouslySpentcorrectly:
- Uses the new
WriteAddressPreviouslySpentmethod for persistence- Directly sets the
previously_spentfield in address book data- Maintains the same logic flow as before
2702-2710: LGTM! Straightforward refactoring of load methods.Both
LoadAddressPreviouslySpentandLoadAddressReceiveRequestcorrectly populate the new typed fields inm_address_book.
2712-2716: LGTM! Clean implementation of status check.
IsAddressPreviouslySpentproperly checks thepreviously_spentfield 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:
GetAddressReceiveRequestsiterates over the typedreceive_requestsmapSetAddressReceiveRequestuses the newWriteAddressReceiveRequestmethod- New
EraseAddressReceiveRequestprovides deletion functionality
All methods correctly manipulate them_address_bookentries directly.
- Simplify overly detailed comment in setAddressReceiveRequest method - Remove editorial commentary about potential improvements - Keep only essential information relevant to current functionality Addresses CodeRabbit feedback about excessive interface design commentary being inappropriate for a backport context.
