58-63: Unnecessary transaction initiation inReset()methodStarting a new transaction with
b.db.Begin()in theReset()method may lead to redundant or nested transactions, which can cause unexpected behavior. Transaction management should be consistent and centralized.Consider removing the transaction initiation from the
Reset()method if it's not required, and ensure that transactions are properly managed in theWrite()method or other appropriate locations.Apply this diff to remove the unnecessary transaction initiation:

88-91: Handle Iterator Stepping Errors AppropriatelyThe use of
itr.statement.Step()correctly handles advancing the iterator. However, consider whether additional context in the error message would be beneficial for debugging purposes.You might enhance the error message by including information about the current state or the query being executed.
135-137: Simplify the Logic inValid()MethodThe
Valid()method contains a redundant check that can be simplified for clarity.Apply this diff to simplify the method:
func (itr *iterator) Valid() bool { - if !itr.valid { - return itr.valid - } + if !itr.valid { + return false + } // if key is at the end or past it, consider it invalid if end := itr.end; end != nil { if bytes.Compare(end, itr.Key()) <= 0 { itr.valid = false - return itr.valid + return false } } return true }
151-157: Consider Error Handling Enhancements inNext()MethodIn the
Next()method, after callingitr.statement.Step(), you setitr.validtofalseif an error occurs or there are no more rows. Ensure that this behavior aligns with the expected iterator semantics, and consider whether additional error logging or handling is necessary.Would you like assistance in reviewing the error handling logic to ensure robustness?

store/v2/go.mod (3)
Line range hint 30-49: Review indirect dependency changes.
The changes align with the PR objective of standardizing SQLite library usage:
- Added
bvinc/go-sqlite-literelated dependencies - Removed
mattn/go-sqlite3dependencies
10-17: Verify IAVL version compatibility.
The changes introduce both IAVL v1 and v2 as direct dependencies. While this aligns with the PR objective to add iavl/v2 support, we should ensure that both versions can coexist without conflicts.
✅ Verification successful
IAVL version coexistence verified as safe
The codebase shows a clean separation between IAVL v1 and v2 usage:
- IAVL v1 is used in existing store implementations (
store/iavl/,store/rootmulti/) - IAVL v2 is isolated to new v2 store implementation (
store/v2/commitment/iavlv2/) - No file imports both versions simultaneously except
go.modandgo.sum - The only shared file showing both versions (
store/v2/commitment/iavlv2/tree.go) only imports v2

37-37: LGTM: SQLite library migration
The addition of github.com/bvinc/go-sqlite-lite aligns with the PR objectives to standardize SQLite library usage across the codebase. The chosen library provides better explicit locking mechanisms.
52-52: Verify btree version update compatibility
The update of github.com/google/btree from v1.1.2 to v1.1.3 needs verification to ensure no breaking changes.
✅ Verification successful
Let me analyze the btree version update by checking the changelog and actual usage.
Let me check the actual btree usage in the memdb implementation to understand the impact.
Let me check the changelog between btree v1.1.2 and v1.1.3 to understand the changes.
Based on the analysis of the code and version update:
- The btree package is only used in the in-memory database implementation (MemDB) in store/v2/db/memdb.go
- The update is a minor version bump (v1.1.2 to v1.1.3) which indicates backward compatibility
- The MemDB implementation uses only the core btree functionality (New, Get, Has, ReplaceOrInsert, Delete, Ascend, Descend, etc.) which are stable APIs in the btree package
- The usage pattern is straightforward and doesn't rely on any advanced or potentially changed features
The update from btree v1.1.2 to v1.1.3 is safe and compatible

50-50: LGTM: SQLite library migration.
The addition of github.com/bvinc/go-sqlite-lite and removal of github.com/mattn/go-sqlite3 aligns with the PR objectives to standardize the SQLite library implementation. The chosen library's explicit locking mechanisms should provide better control over concurrent database access.
67-67: Verify compatibility with updated btree version.
The indirect dependency update of github.com/google/btree from v1.1.2 to v1.1.3 should be verified for compatibility with the new SQLite implementation.
✅ Verification successful
Let me search for actual btree usage in the codebase to verify if there are any direct dependencies that could be affected by the version update.
No compatibility concerns with btree v1.1.3 update
The codebase uses btree in a way that is compatible with the v1.1.3 update. The changes between v1.1.2 and v1.1.3 were minor and did not introduce breaking changes. The main usage patterns found in the codebase:
- Basic BTree operations (Get, Set, Delete) in store/v2/db/memdb.go
- Generic BTreeG usage in server/v2/stf/branch and store/cachekv/internal
- Simple btree.Map usage in schema/testing and collections packages
All these patterns remain fully supported in v1.1.3 with no API changes.

63-63: Verify SQLite library standardization across modules.
The addition of github.com/bvinc/go-sqlite-lite aligns with the PR objective of standardizing SQLite library usage. However, we should ensure this transition is complete across all affected modules.
Let's verify the SQLite library standardization:
✅ Verification successful
Based on the go.mod files analysis, I can see that the SQLite library transition is consistent across the codebase. The following modules have adopted github.com/bvinc/go-sqlite-lite:
- server/v2/cometbft/go.mod
- simapp/v2/go.mod
- store/v2/go.mod
- runtime/v2/go.mod
- server/v2/go.mod
Let's verify the actual SQLite usage in the code to ensure complete transition:
SQLite library transition is complete and consistent
The verification confirms that the SQLite library transition is complete and properly implemented:
- All SQLite-related code in
store/v2/storage/sqlite/consistently usesgithub.com/bvinc/go-sqlite-lite/sqlite3 - No references to the old
mattn/go-sqlite3library were found in the codebase - The only other SQL usage is in the postgres indexer which correctly uses the standard

10-11: Import Statement Correctly Added
The import statement for the new SQLite library github.com/bvinc/go-sqlite-lite/sqlite3 is correctly added and appropriately grouped.
18-18: Update Iterator Struct with New Statement Type
The statement field in the iterator struct is updated to use *sqlite3.Stmt, aligning with the new SQLite library's types.
77-80: Ensure Binding Parameters Match SQL Query Placeholders
When binding parameters using stmt.Bind(queryArgs...), ensure that the number of placeholders in the SQL query matches the number of elements in queryArgs. Mismatches could lead to runtime errors or unexpected behavior.
To confirm that the placeholders and arguments are correctly matched, you can review the SQL statement and the queryArgs slice.
35-35:
Avoid Casting from uint64 to int64 to Prevent Potential Overflow
Casting version from uint64 to int64 may lead to negative values or overflow issues when dealing with very large version numbers exceeding math.MaxInt64. This could cause unexpected behavior in the SQL query.
Consider the following solutions:
- Solution 1 (preferred): Modify the database schema to store version numbers as unsigned integers, if supported, to match the
uint64type. - Solution 2: Add a check to ensure that
versiondoes not exceedmath.MaxInt64before casting, and handle the error appropriately if it does.
To verify if any version numbers exceed math.MaxInt64 in the codebase, you can run the following script:
store/v2/storage/sqlite/db.go (3)
165-167: Check for errors when setting the latest version
While locking is correctly applied, consider handling possible errors from db.storage.Exec.
Ensure that the SetLatestVersion method handles all potential errors:
err := db.storage.Exec(reservedUpsertStmt, reservedStoreKey, keyLatestHeight, int64(version), 0, int64(version))
+if err != nil {
+ return fmt.Errorf("failed to set latest version: %w", err)
+}202-222: Handle possible SQL errors and edge cases in Get method
Ensure all errors from SQL operations are checked and handled appropriately, and consider the implications of the tombstone logic.
Review error handling for stmt.Bind, stmt.Step, and stmt.Scan to ensure robustness.
127-132:
Prevent error overwriting in deferred function
Assigning to the named return variable err within a deferred function can overwrite any existing errors, potentially causing loss of important error information.
Modify the deferred function to wrap the error without overwriting the original:
defer func(stmt *sqlite3.Stmt) {
if cErr := stmt.Close(); cErr != nil {
err = fmt.Errorf("failed to close GetLatestVersion statement: %w", cErr)
}
}(stmt)Alternatively, log the close error if it's less critical.

- Connection handling under concurrent load
Would you like me to help generate additional test cases for these scenarios?
store/v2/commitment/iavlv2/tree.go (4)
99-100: Name the parameter in thePausePruningmethodThe parameter in the
PausePruningmethod is unnamed. According to the Uber Go Style Guide, all parameters should be named for clarity, even if they are not used. This improves code readability and consistency.Apply this diff to name the parameter:
-func (t *Tree) PausePruning(bool) {} +func (t *Tree) PausePruning(enable bool) {}
54-60: Address the TODO: FixLoadVersionbehavior in IAVL v2The
LoadVersionmethod contains a TODO comment indicating that there is an issue when loading version 0. This might cause unexpected behavior if version 0 is a valid version in certain contexts. Consider resolving this TODO by implementing the necessary fix or providing a clear explanation of the limitation.Would you like assistance in addressing this TODO or would you like me to open a GitHub issue to track this task?
23-30: Consider renaming the variablesqlto avoid confusionIn the
NewTreefunction, the variablesqlis used to store the SQLite database connection. Sincesqlis commonly associated with the standard library packagedatabase/sql, using it as a variable name may cause confusion. Consider renaming the variable todborsqliteDBfor better clarity.Apply this diff to rename the variable:
-func NewTree(treeOptions iavl.TreeOptions, dbOptions iavl.SqliteDbOptions, pool *iavl.NodePool) (*Tree, error) { - sql, err := iavl.NewSqliteDb(pool, dbOptions) +func NewTree(treeOptions iavl.TreeOptions, dbOptions iavl.SqliteDbOptions, pool *iavl.NodePool) (*Tree, error) { + db, err := iavl.NewSqliteDb(pool, dbOptions) if err != nil { return nil, err } - tree := iavl.NewTree(sql, pool, treeOptions) + tree := iavl.NewTree(db, pool, treeOptions) return &Tree{tree: tree}, nil }
32-104: Add documentation comments to exported methodsThe exported methods of the
Treestruct lack documentation comments. According to Go conventions and the Uber Go Style Guide, all exported functions and methods should have comments explaining their purpose and usage. This enhances code readability and helps other developers understand the functionality.Would you consider adding appropriate documentation comments to each exported method?
store/v2/storage/sqlite/iterator.go (4)
Line range hint
135-142: Simplify and correct theValidmethod logic.The
Validmethod should accurately reflect the iterator's state. Ensure that it doesn't returntruewhen the iterator has become invalid due to reaching the end.Consider refactoring the
Validmethod:if !itr.valid { return false } if end := itr.end; end != nil { if bytes.Compare(end, itr.Key()) <= 0 { itr.valid = false - return itr.valid + return false } } return trueThis makes the return values explicit and improves readability.
77-80: Ensure statement is properly closed on error during binding.The error handling when binding parameters should reliably close the statement to prevent resource leaks.
Consider checking the error from
stmt.Close():err = stmt.Bind(queryArgs...) if err != nil { - _ = stmt.Close() + closeErr := stmt.Close() + if closeErr != nil { + return nil, fmt.Errorf("failed to close statement after bind error: %w; original error: %v", closeErr, err) + } return nil, fmt.Errorf("failed to bind SQL iterator query arguments: %w", err) }This ensures that any errors during closure are also captured and reported.
10-11: Organize imports according to style guidelines.Imports should be grouped and separated into standard library imports, third-party imports, and local package imports.
Reorganize the imports for clarity:
import ( "bytes" "database/sql" "fmt" "slices" "strings" - "github.com/bvinc/go-sqlite-lite/sqlite3" corestore "cosmossdk.io/core/store" + + "github.com/bvinc/go-sqlite-lite/sqlite3" )This improves readability and maintains consistency with the Uber Golang style guide.
25-25: Function documentation is missing.Public functions should have a comment describing their purpose and usage.
Add a comment for the
newIteratorfunction:+ // newIterator creates a new iterator for the given parameters. func newIterator(db *Database, storeKey []byte, version uint64, start, end []byte, reverse bool) (*iterator, error) {This enhances the maintainability of the codebase.

109-114: Avoid opening a new connection for each batch.In the
NewBatchmethod, a new database connection is opened for each batch. This can lead to resource exhaustion and decreased performance due to the overhead of establishing connections.Consider reusing the existing connection or implementing a connection pool to manage multiple connections efficiently.
238-239: Review the necessity ofwriteLockfor concurrency control.The use of
writeLock *sync.Mutexsuggests thatsqlite3.Connmay not be safe for concurrent writes. Confirm whether the SQLite driver handles concurrency internally or if external synchronization is required.Consider documenting the concurrency model or exploring alternative approaches if the mutex is unnecessary or could lead to performance bottlenecks.

30-30: Review indirect dependency additions
New indirect dependencies have been added:
- github.com/aybabtme/uniplot: Plotting library
- github.com/dustin/go-humanize: Human-readable numbers
- github.com/kocubinski/costor-api: Custom API
These seem to be pulled in by the IAVL v2 dependency. While they don't directly affect the codebase, it's good to be aware of the additional dependencies being introduced.

fi10-10: Verify SQLite library migration completeness
The PR objectives mention migrating from mattn/go-sqlite3 to bvinc/go-sqlite-lite. Let's verify that all SQLite-related code has been updated to use the new library.
✅ Verification successful
Let me try a different search approach to verify the SQLite library migration.
SQLite migration is complete and consistent
The codebase shows a complete migration to bvinc/go-sqlite-lite. All SQLite-related code consistently uses the new library through the github.com/bvinc/go-sqlite-lite/sqlite3 import. There are no references to the old mattn/go-sqlite3 library, and the implementation in store/v2/storage/sqlite/ package properly uses the new library's APIs.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check for any remaining references to the old SQLite library

#!/bin/bash
# Search for SQLite-related imports and usage patterns
rg -i "sqlite" --type go
# Look for database connection/initialization code
ast-grep --pattern 'sql.Open($$$)'
Length of output: 4174
10-10: Verify IAVL version compatibility
The changes introduce both IAVL v1 and v2 as direct dependencies. While this might be intentional for migration purposes, we should ensure that:
- Both versions can coexist without conflicts
- There's a clear migration path from v1 to v2
Also applies to: 14-15
✅ Verification successful
Let me analyze the IAVL version usage in the codebase to verify compatibility and migration concerns.
Let me check one more aspect to understand the IAVL v2 implementation details.
IAVL v1 and v2 coexistence is properly managed
Based on the analysis of the codebase:
- IAVL v2 is cleanly isolated in
store/v2/commitment/iavlv2package with a proper abstraction layer - IAVL v1 (v1.3.0) is used as an indirect dependency in various x/ modules
- IAVL v2 is only used in store/v2, indicating a clear separation of concerns
- The implementation shows proper version handling and compatibility considerations
The coexistence is intentional and well-structured, with v2 being introduced alongside v1 in a way that prevents conflicts. The migration path is clear - v2 is being introduced in the new store/v2 package while maintaining backward compatibility with v1 in existing modules.

52-52: Verify the impact of btree version update.
The minor version bump of google/btree from v1.1.2 to v1.1.3 might introduce changes that could affect performance or behavior.
✅ Verification successful
Let me check the actual usage of btree in the codebase to better understand the impact.
Let me check the changelog between v1.1.2 and v1.1.3 by looking at the commit history since the GitHub API didn't return the release notes.
The btree v1.1.3 update is safe to proceed with
The update from v1.1.2 to v1.1.3 contains a single bugfix for copy-on-write operations during item removal in cloned trees. After reviewing the codebase, the MemDB implementation uses basic btree operations (Get, Has, ReplaceOrInsert, Delete) and doesn't utilize tree cloning functionality, so this bugfix doesn't impact the current usage.

💡 Codebase verification
Consider using a more actively maintained SQLite library
The current choice of github.com/bvinc/go-sqlite-lite v0.6.1 raises several concerns:
- The library hasn't been updated since May 2019 (last commit: 2019-05-02)
- There are unresolved module-related issues (Issue Fee as type Coins instead of Coin #25)
- The SQLite version is significantly outdated (Issue CLI Updates, Coin fix #26)
- No response to issues or maintenance activity for over 4 years
Consider evaluating alternative SQLite libraries with explicit locking mechanisms that are actively maintained, such as:
modernc.org/sqlitegithub.com/glebarez/go-sqlite

@kocubinski, that's a great point. Modernc.org/sqlite, being a pure Go implementation, could indeed avoid conflicts with iavl/v2 and potentially offer better performance.
From the information gathered:
- Latest version: v1.33.1
- Active maintenance: The library has recent updates and ongoing issue discussions.
- Open issues: There are some open issues to consider, such as performance optimizations.
It seems like a promising alternative worth evaluating. Let me know if you need any assistance with this.

Learning: In `store/v2/storage/sqlite/batch.go`, the `lock` in the `Batch` struct is used to synchronize concurrent writers to the SQLite database, and the `Batch` methods (`Set()`, `Delete()`, `Reset()`) are designed for single-threaded access.

4-8: LGTM: Import changes align with migration to go-sqlite-lite
The import changes correctly implement the migration from mattn/go-sqlite3 to bvinc/go-sqlite-lite as specified in the PR objectives.
58-61: Refer to existing review comment about transaction management in Reset
A previous review has already identified the transaction management issue in the Reset method.
78-89: LGTM: Proper transaction and error handling
The implementation correctly handles:
- Write synchronization using mutex
- Transaction rollback on error
- Error joining for comprehensive error reporting
29-33: 🛠️ Refactor suggestion
Consider using uint64 for version consistency
The version field is defined as int64 but is used with uint64 throughout the codebase. This type mismatch could lead to potential issues.
type Batch struct {
db *sqlite3.Conn
lock *sync.Mutex
ops []batchOp
size int
- version int64
+ version uint64
}Likely invalid or redundant comment.
90-104: 🛠️ Refactor suggestion
Consider using parameterized queries for SQL statements
The SQL statements (reservedUpsertStmt, upsertStmt, delStmt) should be parameterized to prevent SQL injection vulnerabilities.
Consider defining the statements as prepared statements during initialization:
type Batch struct {
// ... existing fields ...
stmtReservedUpsert *sqlite3.Stmt
stmtUpsert *sqlite3.Stmt
stmtDelete *sqlite3.Stmt
}

🛠️ Refactor suggestion
Improve transaction handling in Prune method.
The transaction commit should be handled in the deferred function to ensure proper cleanup.
func (db *Database) Prune(version uint64) (err error) {
v := int64(version)
db.writeLock.Lock()
defer db.writeLock.Unlock()
err = db.storage.Begin()
if err != nil {
return fmt.Errorf("failed to create SQL transaction: %w", err)
}
+ committed := false
defer func() {
- if err != nil {
+ if !committed {
err = errors.Join(db.storage.Rollback())
}

Could you please add the tree test like iavl v1?
Description
Adds support for iavl/v2 as a commitment backend.
Required for this work is to converge on a single sqlite library to use in both iavl/v2 and store/v2/storage/sqlite. store/v2/storage/sqlite has been migrated in this PR to github.com/bvinc/go-sqlite-lite from github.com/mattn/go-sqlite3.
bvincis a bit more explicit, particularly around not hiding locking, so some changes were required to bring the implementation into alignment.Author Checklist
