4-4: Address TODO: Add tests for transaction description generationThere's a TODO comment indicating that tests need to be added. Given the critical nature of transaction description generation and the recent changes to the locking mechanism, it's crucial to ensure proper test coverage.
Consider adding the following types of tests:
- Unit tests for the
toHTMLfunction with various transaction types (normal, Spark, coinbase, etc.).- Tests that simulate lock acquisition failures to ensure proper handling of edge cases.
- Integration tests that verify the generated HTML output for different transaction scenarios.

73-78: Concurrent Locks: Verify lock acquisition order to prevent deadlocks.When acquiring multiple locks (
cs_mainandwallet->cs_wallet), it's crucial to maintain a consistent lock acquisition order across the codebase to prevent potential deadlocks.

If not, consider reordering the locks or refactoring to a higher-level locking strategy to avoid deadlocks.

Potential Data Inconsistency When Failing to Acquire Lock in setMasternodeList
By using TRY_LOCK(cs_mnlinst, lock); and returning early if the lock is not acquired, there's a possibility that mnListCached is not updated when it should be. This could lead to the masternode list being outdated, causing inconsistencies in the UI or other components that rely on this data.
Consider implementing a mechanism to ensure that the masternode list remains consistent, even when the lock can't be acquired immediately. For example, you might queue the update to be retried or ensure that the caller is aware of the failure to update.

Returning Empty Masternode List May Cause Misinterpretation
In getMasternodeList(), if the lock isn't acquired, the function returns an empty CDeterministicMNList(). Callers might interpret this as there being no masternodes available, rather than a temporary inability to access the data due to lock contention.
Consider returning a status indicator or an optional value to distinguish between an empty masternode list and a failure to acquire the lock. This can help prevent misinterpretation by the caller.

🛠️ Refactor suggestion
Refactor repetitive lock acquisition code into a helper function
The following lock acquisition pattern is repeated in multiple methods:
TRY_LOCK(cs_main, lock_main);
if (!lock_main)
return; // or return false;
TRY_LOCK(wallet->cs_wallet, lock_wallet);
if (!lock_wallet)
return; // or return false;Consider refactoring this code into a helper function to reduce duplication and improve maintainability.

bool WalletModel::tryLockChainAndWallet() const {
TRY_LOCK(cs_main, lock_main);
if (!lock_main)
return false;
TRY_LOCK(wallet->cs_wallet, lock_wallet);
if (!lock_wallet)
return false;
return true;
}Then, the methods can use:
if (!tryLockChainAndWallet())
return; // or return false;Also applies to: 760-765, 777-783, 836-841, 847-852, 859-864, 871-876, 882-887, 893-898

Handle locking failures appropriately in hasMasternode()
In the hasMasternode() method:
if (!lock_main)
return false;
if (!lock_wallet)
return false;
return wallet->HasMasternode();Returning false when locks are not acquired might mislead the caller into thinking that there is no masternode, whereas the status is actually unknown due to locking failure.
Consider handling the locking failure separately or retrying the lock acquisition to provide accurate information.

40-45: Consider UI implications of non-blocking locks.
While the switch to TRY_LOCK improves responsiveness by preventing thread blocking (especially beneficial for large wallets), it could lead to UI value flickering as noted in the previous review. The UI might briefly show cached values when locks can't be acquired, then update to new values when locks succeed.
Consider these alternatives:
- Add a small delay before returning cached value to reduce update frequency
- Implement a debouncing mechanism in the UI layer
- Add value smoothing to prevent jarring updates
Would you like me to provide implementation examples for any of these approaches?

The updateConfirmations() function now updates a maximum of 300 rows, reduced from 1000. Please verify that this change does not negatively affect users with transaction histories longer than 300 entries, as it may result in some transaction confirmations not being updated in the UI.

316-316: Consider a dynamic row limit based on wallet sizeThe hard-coded limit of 300 rows might be too restrictive for large wallets and unnecessary for small ones.
Consider making the limit configurable or dynamic:

The implementation is functionally correct, but please address the concerns raised in the previous review comments about potential data inconsistency and stale data risks.
106-110: LGTM! Effective caching implementation.
The caching mechanism for block height is well-implemented, using atomic operations and proper lock handling. This change aligns well with the PR's performance improvement goals.

Consider adding error handling and user feedback for lock failures
While the change from LOCK2 to TRY_LOCK improves UI responsiveness by preventing thread blocking, returning an empty string silently might confuse users. This is particularly important for users with large wallets, which is a focus of this PR.
Consider these improvements:
QString TransactionDesc::toHTML(CWallet *wallet, CWalletTx &wtx, TransactionRecord *rec, int unit)
{
QString strHTML;
+ const int MAX_RETRIES = 3;
+ const int RETRY_DELAY_MS = 100;
+
+ for (int retry = 0; retry < MAX_RETRIES; ++retry) {
TRY_LOCK(cs_main,lock_main);
if (!lock_main) {
- return strHTML;
+ if (retry == MAX_RETRIES - 1) {
+ LogPrintf("TransactionDesc::toHTML: Failed to acquire cs_main lock after %d attempts\n", MAX_RETRIES);
+ return tr("Transaction details temporarily unavailable. Please try again in a few moments.");
+ }
+ MilliSleep(RETRY_DELAY_MS);
+ continue;
}
TRY_LOCK(wallet->cs_wallet,lock_wallet);
if (!lock_wallet) {
+ if (retry == MAX_RETRIES - 1) {
+ LogPrintf("TransactionDesc::toHTML: Failed to acquire wallet lock after %d attempts\n", MAX_RETRIES);
+ return tr("Transaction details temporarily unavailable. Please try again in a few moments.");
+ }
+ MilliSleep(RETRY_DELAY_MS);
+ continue;
}
+
+ // Both locks acquired successfully
+ break;
+ }This improvement:
- Adds a retry mechanism to handle temporary lock contention
- Provides user feedback when locks can't be acquired
- Logs lock acquisition failures for debugging
- Maintains the non-blocking behavior while reducing the likelihood of showing empty transaction details

95-98: Ensure sparkModel is properly initialized before use
In the getAnonymizableBalance() method, sparkModel is accessed without checking if it is initialized. Although sparkModel is initialized in the constructor, it's safer to verify its initialization before use to prevent potential null pointer dereferences.

if (sparkModel && spark::IsSparkAllowed()) {
amount = sparkModel->getMintableSparkAmount();
}

Add null check for model->getWallet() to prevent potential null pointer dereference
In the condition, model->getWallet() is accessed without verifying that it's not null. This could lead to a crash if getWallet() returns null.
