Merge bitcoin/bitcoin#29403: wallet: batch erase procedures and improve 'EraseRecords' performance #1096
Conversation
…eRecords' performance 77331aa wallet: simplify EraseRecords by using 'ErasePrefix' (furszy) 3375781 wallet: bdb batch 'ErasePrefix', do not create txn internally (furszy) cf4d72a wallet: db, introduce 'RunWithinTxn()' helper function (furszy) Pull request description: Seeks to optimize and simplify `WalletBatch::EraseRecords`. Currently, this process opens a cursor to iterate over the entire database, searching for records that match the type prefixes, to then call the `WalletBatch::Erase` function for each of the matching records. This PR rewrites this 40-line manual process into a single line; instead of performing all of those actions manually, we can simply utilize the `ErasePrefix()` functionality. The result is 06216b3. Moreover, it expands the test coverage for the `ErasePrefix` functionality and documents the db txn requirement for `BerkeleyBatch::ErasePrefix` .

Bug: BerkeleyBatch ErasePrefix Cursor Handling Bug
The BerkeleyBatch::ErasePrefix method incorrectly handles cursor positioning after deleting records. After m_cursor->del(0), the Berkeley DB cursor position becomes undefined. The loop then attempts to use m_cursor->get with DB_NEXT on this invalid cursor, violating the API contract. This can cause the function to skip records (e.g., every other matching record), fail unexpectedly, or exhibit undefined behavior, leading to incomplete prefix erasure. Additionally, the ret variable is reused for both delete and get operations, which can lead to incorrect error reporting (e.g., returning false when deletions succeeded).

819-844: Fix: Cursor invalidation after del() may skip records — reposition with DB_SET_RANGEAfter
m_cursor->del(0), the cursor position is undefined in Btree. Callingget(..., DB_NEXT)next can skip every other key or hit UB. Re-seek to the next key >= prefix usingDB_SET_RANGEafter each delete.Apply this minimal, safe refactor:
bool BerkeleyBatch::ErasePrefix(Span<const std::byte> prefix) { - // Because this function erases records one by one, ensure that it is executed within a txn context. - // Otherwise, consistency is at risk; it's possible that certain records are removed while others - // remain due to an internal failure during the procedure. - // Additionally, the Dbc::del() cursor delete call below would fail without an active transaction. - if (!Assume(activeTxn)) return false; - - if (!StartCursor()) return false; - - // const_cast is safe below even though prefix_key is an in/out parameter, - // because we are not using the DB_DBT_USERMEM flag, so BDB will allocate - // and return a different output data pointer - SafeDbt prefix_key(const_cast<std::byte*>(prefix.data()), static_cast<uint32_t>(prefix.size())); - SafeDbt prefix_value; - int ret = m_cursor->get(prefix_key, prefix_value, DB_SET_RANGE); - for (int flag = DB_CURRENT; ret == 0; flag = DB_NEXT) { - SafeDbt key, value; - ret = m_cursor->get(key, value, flag); - if (ret != 0 || key.get_size() < prefix.size() || memcmp(key.get_data(), prefix.data(), prefix.size()) != 0) break; - ret = m_cursor->del(0); - } - CloseCursor(); - return ret == 0 || ret == DB_NOTFOUND; + // Must run within a write txn; cursor deletions require it and we want atomicity. + if (!Assume(activeTxn)) return false; + if (!StartCursor()) return false; + + // Seek to the first key >= prefix + SafeDbt seek_key(const_cast<std::byte*>(prefix.data()), static_cast<uint32_t>(prefix.size())); + SafeDbt unused_val; + int ret = m_cursor->get(seek_key, unused_val, DB_SET_RANGE); + + while (ret == 0) { + // Read the current record + SafeDbt cur_key, cur_val; + ret = m_cursor->get(cur_key, cur_val, DB_CURRENT); + if (ret != 0) break; + + // Stop once we move past the prefix range + if (cur_key.get_size() < prefix.size() || + memcmp(cur_key.get_data(), prefix.data(), prefix.size()) != 0) { + ret = DB_NOTFOUND; + break; + } + + // Delete current record + ret = m_cursor->del(0); + if (ret != 0) break; + + // After deletion, cursor position is undefined. Reposition to next >= prefix. + ret = m_cursor->get(seek_key, unused_val, DB_SET_RANGE); + } + + CloseCursor(); + return ret == 0 || ret == DB_NOTFOUND; }This prevents skipped deletions and adheres to BDB cursor semantics.

**: # 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

Learning: In Dash backports from Bitcoin Core, including necessary compilation fixes (such as API compatibility changes like UniValue get_int() → getInt<int>()) alongside the core backport is standard and expected practice. These compatibility fixes ensure the backported code compiles in Dash's evolved codebase while preserving Bitcoin's original functionality and intent.

- Remove DelAddressBookWithDB and update any call sites to use the upstream DelAddressBook pattern, or
- If this Dash-specific extension is truly required, document the rationale in a comment and link the exact hunk from commit 128b4a8 where it was added.

Verify override scope vs upstream; potential scope creep
The new override ErasePrefix(Span<const std::byte>) is fine interface-wise, but per PR objectives this file wasn’t changed by the original Bitcoin commit. Please confirm upstream 128b4a8 modifies bdb.h; otherwise, this is scope creep and should be dropped or justified as a Dash-specific compatibility need.
Also confirm that the base DatabaseBatch declares this virtual with the same signature; mismatches will break polymorphism.
Would you like me to run a repo script to compare changed files vs Bitcoin commit and flag off-scope files automatically?
🏁 Script executed:
#!/usr/bin/env bash
# Find all references to ErasePrefix in the repository
rg "ErasePrefix" -n
# Locate the DatabaseBatch class definition to verify declaration of ErasePrefix
rg "class DatabaseBatch" -A10 -n srcLength of output: 1114
Add or remove the ErasePrefix declaration in the DatabaseBatch interface
The override in src/wallet/bdb.h will fail because the base class does not declare ErasePrefix. Either:
- Reinstate upstream behavior by dropping this Dash-only method (scope creep), or
- Add the matching pure-virtual declaration to
DatabaseBatchso theoverridecompiles, and confirm that the original Bitcoin Core commit (128b4a8) introduced it.
Files to update:
- src/wallet/db.h: insert
virtual bool ErasePrefix(Span<const std::byte> prefix) = 0;
in the public section alongsideEraseKey. - src/wallet/bdb.h: keep or remove the
overridebased on the choice above.
Fixes required before merging.
🤖 Prompt for AI Agents
In src/wallet/bdb.h at line 197, the ErasePrefix method is marked override but
the base class DatabaseBatch does not declare it, causing a compilation error.
To fix this, add a pure virtual declaration `virtual bool ErasePrefix(Span<const
std::byte> prefix) = 0;` to the public section of src/wallet/db.h alongside
EraseKey. Then keep the override in bdb.h so it matches the base class. This
aligns with the original Bitcoin Core commit and resolves the override mismatch.

case from LoadReceiveRequests to LoadReceiveRequests_DBFormats to avoid
duplicate test names. Additionally, in src/wallet/walletdb.h, declare the
missing WalletBatch methods WriteAddressPreviouslySpent and EraseAddressData,
and implement their definitions in walletdb.cpp, or alternatively update the
test code to use the correct existing WalletBatch API methods for these

⚙️ CodeRabbit Configuration File
**: # 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

Learning: DashCoreAutoGuix successfully completed a complex Bitcoin Core backport (PR #29412) for block mutation detection by implementing the IsBlockMutated function, adding net processing integration, creating comprehensive unit tests, and properly adapting all Bitcoin-specific witness code for Dash compatibility. The backport maintains full security functionality while respecting Dash's non-witness transaction architecture.

Learning: In Dash backports from Bitcoin Core, when converting function parameters from std::string to std::string_view, the find_value() method calls require explicit conversion back to std::string using std::string() wrapper, as find_value() expects std::string parameters in Dash's UniValue implementation.

33-34: No missing ErasePrefix overrides in DatabaseBatch subclassesAll direct subclasses of DatabaseBatch now correctly implement the new pure-virtual
ErasePrefixmethod:
- src/wallet/bdb.h: BerkeleyBatch overrides
bool ErasePrefix(Span<const std::byte>)- src/wallet/sqlite.h: SQLiteBatch overrides
bool ErasePrefix(Span<const std::byte>)- src/wallet/db.h: DummyBatch overrides
bool ErasePrefix(Span<const std::byte>)Since each backend provides its own override, adding the pure-virtual declaration does not introduce any ABI or compile-time breakage.

WalletBatch::WriteAddressPreviouslySpent,EraseAddressData,EraseAddressReceiveRequest, and relies onRunWithinTxn(). Please ensure these functions are declared inwalletdb.hand defined for every backend (Berkeley, SQLite). Missing implementations will link-fail only for the back-end not built by default.src/wallet/walletdb.h (2)

267-279: Verified RunWithinTxn alignment
Header declaration at src/wallet/walletdb.h:279 matches implementation at src/wallet/walletdb.cpp:1088. The static helper overload for WalletBatch is intentional and no extra or missing definitions are present. No further changes needed.src/wallet/walletdb.cpp (4)

1167-1174: Fix cursor-positioning bug in BerkeleyBatch::ErasePrefixThe current loop deletes the record under the cursor before fetching the next key, which leaves the cursor in an undefined state and can skip or miss entries. We need to prefetch the next key/value pair before calling

🧹 Nitpick (assertive)
Order-dependent assertions may be flaky
GetAddressReceiveRequests() returns a std::vector. Relying on the order when comparing to {"val_rr11","val_rr20"} can fail if the backend changes iteration order. To make the test backend-agnostic, compare unordered collections instead, e.g.:
std::unordered_set<std::string> expected{"val_rr11","val_rr20"};
BOOST_CHECK_EQUAL_COLLECTIONS(expected.begin(), expected.end(),
requests.begin(), requests.end());🤖 Prompt for AI Agents
In src/wallet/test/wallet_tests.cpp around lines 477 to 481, the test compares
the vector returned by GetAddressReceiveRequests() to an expected list assuming
order, which can cause flaky tests if the order changes. To fix this, convert
both the expected values and the actual requests to unordered sets and then
compare them, ensuring the test is order-independent and backend-agnostic.

Missing ErasePrefix implementation in SQLiteBatch
Verified that:
- DatabaseBatch declares a pure-virtual
ErasePrefix(Span<const std::byte> prefix)insrc/wallet/db.h:33. - BerkeleyBatch overrides it (
src/wallet/bdb.h:197, implemented insrc/wallet/bdb.cpp:819). - SQLiteBatch (in
src/wallet/sqlite.h) does not override it and thus falls back to the no-op stub found indb.h, makingEraseRecordsa no-op on the SQLite backend.
Please add and implement the override in the SQLite backend:
- src/wallet/sqlite.h
class SQLiteBatch : public DatabaseBatch { public: // … bool ErasePrefix(Span<const std::byte> prefix) override; // … };
- src/wallet/sqlite.cpp
bool SQLiteBatch::ErasePrefix(Span<const std::byte> prefix) { // Execute DELETE statement or forward to SQLiteDatabase to remove all keys matching prefix return m_database.ErasePrefix(prefix); }
This will ensure that WalletBatch::EraseRecords works consistently across both backends.
🤖 Prompt for AI Agents
In src/wallet/sqlite.h around line 254-255, add an override declaration for the
pure-virtual method ErasePrefix(Span<const std::byte> prefix) in the SQLiteBatch
class. Then in src/wallet/sqlite.cpp, implement SQLiteBatch::ErasePrefix to call
m_database.ErasePrefix(prefix) and return its result. This will ensure the
SQLite backend properly supports ErasePrefix and that EraseRecords works
consistently across backends.
