9-11: Consider adding mutex protection for the global variableThe global
normalClientvariable is accessed and modified from different functions without synchronization. This could lead to race conditions in concurrent usage scenarios.Consider adding mutex protection:
var ( + normalClientMutex sync.RWMutex normalClient *fastdialer.Dialer )
Line range hint
31-34: Address the TODO comment about unused parametersThe function accepts
optionsandconfigurationparameters but doesn't use them. This could be misleading for users of the API.Consider either:
- Using the parameters to customize the client behavior, or
- Removing the unused parameters:
-func Get(options *types.Options, configuration *Configuration) (*fastdialer.Dialer, error) { +func Get() (*fastdialer.Dialer, error) { return normalClient, nil }
Line range hint
14-20: Ensure thread-safe initialization with Clear functionThe
Initfunction needs to be synchronized with the newClearfunction to prevent race conditions.Consider adding proper synchronization:
func Init(options *types.Options) error { + normalClientMutex.Lock() + defer normalClientMutex.Unlock() // Don't create clients if already created in the past. if normalClient != nil { return nil } normalClient = protocolstate.Dialer return nil }

Line range hint 1-42: Verify the impact on existing client pool usage
Let's verify how this client pool is used across the codebase to ensure the Clear function won't cause issues.
✅ Verification successful
Based on the search results, I can now generate the final response:
Client pool changes appear safe to proceed
The changes to the client pool implementation are safe because:
- The client pool is properly initialized via
protocolinit.Init() - Usage is consistent across protocols (network, ssl, websocket) with proper error handling
- The
Clear()function is only resetting a global variable, with no direct connection to levelDB operations - No complex state management or cleanup requirements were found
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for usage patterns of the client pool
echo "Searching for client pool usage patterns..."
rg -A 3 "networkclientpool\.(Init|Get|Clear)"
# Search for levelDB related code that might be affected
echo "Searching for levelDB related code..."
rg -A 5 "leveldb\.Open"

Enhance documentation and add tests
The documentation for the Clear function is minimal and there are no tests demonstrating its proper usage and thread-safety.
Please add:
- Comprehensive documentation explaining:
- When to use Clear
- Thread-safety considerations
- Potential impacts on existing connections
- Tests covering:
- Basic Clear functionality
- Concurrent Init/Clear operations
- Resource cleanup verification
Would you like me to help create a test suite for this functionality?

Enhance the Clear function implementation
The current implementation has several potential issues:
- No synchronization protection
- No proper cleanup of resources
- No handling of in-flight operations
Consider implementing a more robust clearing mechanism:
func Clear() {
+ normalClientMutex.Lock()
+ defer normalClientMutex.Unlock()
+
if normalClient != nil {
+ // Close any existing connections
+ if closer, ok := normalClient.GetDialer().(io.Closer); ok {
+ _ = closer.Close()
+ }
normalClient = nil
}
}Committable suggestion skipped: line range outside the PR's diff.
Proposed changes
Cached
normalClientmight cause levelDB to be closed (If the engine was closed previously).Adding an option for clearing it.
