209-210: LGTM! Consider adding a brief comment.The function declaration is well-placed among other address-related RPCs and follows the established patterns. Consider adding a brief comment describing the purpose of this RPC, similar to other functions in this file.
Add this comment above the declaration:
+/** Get the total number of addresses with positive balance */ extern UniValue getAddressNumWBalance(const JSONRPCRequest &request);src/rpc/client.cpp (1)
143-143: Follow consistent method naming conventionWhile the functionality is correct, the method name
getAddressNumWBalanceuses mixed case, while other RPC methods in the file use lowercase (e.g.,getaddressbalance,getaddressdeltas). Consider renaming togetaddressnumwbalancefor consistency.src/rpc/server.cpp (1)
334-335: Follow consistent naming convention for RPC commands.The new RPC command

145-145: Method placement and integration looks good.
The new method is well-placed among other address-related operations and follows the class's established patterns.
145-145: Verify the implementation's impact on database performance.
Since this operation requires scanning the address index, let's verify its usage pattern to ensure it won't impact system performance.
✅ Verification successful
Implementation has acceptable performance characteristics
The method findAddressNumWBalance() is implemented with reasonable performance considerations:
- Uses an iterator to scan the address index efficiently
- Maintains a hash map to track unique addresses
- Only processes specific address types (payToPubKeyHash and payToExchangeAddress)
- Used in a non-critical RPC endpoint (getanonymityset)
The implementation follows similar patterns to other address index operations in the codebase and includes interruption points for long-running operations.

143-143: Verify RPC method implementation
The parameter conversion is correctly configured. Let's verify that the corresponding RPC method is properly implemented.
✅ Verification successful
RPC method implementation verified successfully
The getAddressNumWBalance RPC method is properly implemented in src/rpc/misc.cpp. It:
- Takes no parameters
- Requires
-addressindexto be enabled - Returns the count of addresses with positive balance via
pblocktree->findAddressNumWBalance() - Is correctly registered in the RPC server
The parameter count of 0 in the client configuration matches the implementation.

334-335: Verify the implementation of the new RPC command.
Let's ensure the implementation function exists and is properly declared.
✅ Verification successful
Let me check the actual implementation and declaration to verify they match properly.
The RPC command implementation is properly declared and defined ✓
The verification confirms:
- Function is correctly declared in
src/rpc/server.h - Implementation exists in
src/rpc/misc.cppwith proper signature - Function includes help text and parameter validation
- Appropriate checks for address indexing feature

323-323: Consider adding support for additional address types
The current implementation only handles payToPubKeyHash and payToExchangeAddress types. Consider whether other address types should be included in the count.
#!/bin/bash
# Description: Check for all address types used in the codebase
# Search for AddressType usage
ast-grep --pattern 'AddressType::$_'319-319: Verify database cursor initialization
Ensure that the database cursor is properly initialized before use.
✅ Verification successful
Based on the search results, I can now generate the final response as we have sufficient information about cursor initialization patterns in the codebase.
Database cursor initialization is properly handled
The cursor initialization at this location follows the established pattern used throughout the codebase:
- It uses
boost::scoped_ptr<CDBIterator>for automatic resource management - The cursor is properly initialized via
NewIterator() - Validity checks are consistently performed using
pcursor->Valid() - The code includes proper interruption points for thread safety
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for proper cursor initialization and error handling patterns in the codebase
# Search for similar cursor initialization patterns

1021-1023: LGTM! Proper validation of addressindex requirement
The code correctly checks for the address index requirement and provides a clear error message about reindexing.
| if (it != addrMap.end()) { | ||
| it->second += nValue; | ||
| if (it->second <= 0) | ||
| addrMap.erase(it); |
There was a problem hiding this comment.
If it's less that a zero due to the previous vulnerability the result would be incorrect because we erased non-zero amount from the map.
whale or whole? |
Iterates through the whale address index to calculate the total number of addresses with a positive balance.
