New Features

mcp — Opt-in HTTP request metadata bridge for tool handlers (#5550)

Added WithRequestMetadataExtractor option to the MCP server. When set, HTTP request metadata (headers, query parameters, path variables) is captured and injected into each handler's context.Context. Handlers retrieve it via the provided context helpers:
```
server := mcp.NewMcpServer(conf, mcp.WithRequestMetadataExtractor(mcp.DefaultRequestMetadataExtractor))

server.AddTool(tool, func(ctx context.Context, req *mcp.ServerRequest) (*mcp.ToolResult, error) {
    tenantID, _ := mcp.HeaderFromContext(ctx, "X-Tenant-ID")
    userID, _   := mcp.QueryFromContext(ctx, "user_id")
    // ...
})
```
Available helpers: RequestMetadataFromContext, HeaderFromContext, QueryFromContext, PathFromContext. Fully backward-compatible — existing NewMcpServer(c) calls are unaffected.

Bug Fixes

discov — Go 1.26 etcd URI compatibility (#5548)

Go 1.26 enforces strict RFC 3986 URI parsing and rejects comma-separated hosts in the URI authority component. BuildDiscovTarget was producing URIs in the form etcd://host1:2379,host2:2379/key, which broke all gRPC services using etcd service discovery with multiple endpoints on Go 1.26+.

The etcd target URL format has been updated to place hosts in the path and the etcd key in a query parameter:
```
# Before (breaks Go 1.26):
etcd://host1:2379,host2:2379/my-service-key

# After (RFC 3986 compliant, works on all Go versions):
etcd:///host1:2379,host2:2379?key=my-service-key
```
discov — Unbounded memory growth on duplicate etcd PUT events (#5580)

Fixed two related bugs in discov that caused memory to grow without bound in long-running zRPC services:
- Redundant OnAdd calls: handleWatchEvents called OnAdd on every etcd PUT event regardless of whether the value changed (e.g. lease refreshes, watch reconnects). Duplicate PUTs are now skipped; value changes fire OnDelete(old) followed by OnAdd(new) to keep listeners consistent.
- Unbounded slice growth in addKv: Keys were appended to the internal container.values slice unconditionally, causing a single etcd key to accumulate thousands of duplicates over time. addKv now returns early for exact duplicates, and cleans up stale entries when a key moves to a new server address.

Release notes
We are excited to announce the release of go-zero v1.9.3! This release brings several important enhancements and bug fixes that improve the framework's reliability, performance, and alignment with industry best practices.

🎉 Highlights
- Consistent Hash Load Balancing: New gRPC load balancer for session affinity
- gRPC Best Practices: Changed NonBlock default to align with gRPC recommendations
- Improved Distributed Tracing: Fixed gateway trace header propagation
- ORM Improvements: Fixed zero value scanning for pointer destinations
✨ New Features

Consistent Hash Balancer Support (#5246)

Contributor: @zhoushuguang

A new consistent hash load balancer has been added to the zRPC package, enabling session affinity for gRPC services.

Key Features:
- Hash-based request routing to maintain session affinity
- Distributes requests based on a hash key from context
- Minimal request redistribution on node changes
- Built on go-zero's existing core/hash/ConsistentHash implementation
Usage Example:
```
// Set hash key in context
ctx := zrpc.SetHashKey(ctx, "user_123")

// Requests with the same key will be routed to the same backend
resp, err := client.SomeMethod(ctx, req)
```
Configuration:
```
c := zrpc.RpcClientConf{
    Endpoints: []string{"localhost:8080", "localhost:8081"},
    BalancerName: "consistent_hash",  // Use consistent hash balancer
}
```
Benefits:
- Enables stateful service interactions
- Improves cache hit rates on backend services
- Reduces session data synchronization overhead
- Maintains load distribution while supporting affinity
🐛 Bug Fixes

Fixed Gateway Trace Headers (#5256, #5248)

Contributor: @kevwan

Fixed an issue where OpenTelemetry trace propagation headers were not being properly forwarded through the gateway to upstream gRPC services, breaking distributed tracing.

Problem:
The gateway was not forwarding critical W3C Trace Context headers (traceparent, tracestate, baggage) to gRPC metadata, causing trace context to be lost at the gateway boundary.

Solution:
- Enhanced ProcessHeaders function to forward trace propagation headers
- Headers are now properly converted to lowercase per gRPC metadata conventions
- Maintains distributed tracing across HTTP → gRPC boundaries
Impact:
- End-to-end tracing now works correctly through the gateway
- Improved observability for microservice architectures
- Better debugging and performance analysis capabilities
Technical Details:
```
// Trace headers now properly forwarded
var traceHeaders = map[string]bool{
    "traceparent": true,  // W3C Trace Context
    "tracestate":  true,  // Additional trace state
    "baggage":     true,  // W3C Baggage propagation
}
```
Fixed Multiple Trace Initialization (#5244)

Contributor: @kevwan

Problem:
When running multiple services (e.g., REST + RPC) in the same process, the trace agent could be initialized multiple times, potentially causing resource leaks or unexpected behavior.

Solution:
- Used sync.Once to ensure trace agent is initialized only once
- Aligned with similar patterns used in prometheus.StartAgent and logx.SetUp
- Added sync.OnceFunc for shutdown to prevent double cleanup
Code Changes:
```
var (
    once           sync.Once
    shutdownOnceFn = sync.OnceFunc(func() {
        if tp != nil {
            _ = tp.Shutdown(context.Background())
        }
    })
)

func StartAgent(c Config) {
    if c.Disabled {
        return
    }

    once.Do(func() {
        if err := startAgent(c); err != nil {
            logx.Error(err)
        }
    })
}
```
Benefits:
- Prevents resource conflicts in multi-server processes
- Ensures single global tracer provider instance
- Safer concurrent initialization
- Proper cleanup on shutdown
Fixed ORM Zero Value Scanning for Pointer Destinations (#5270)

Contributor: @lerity-yao (first contribution! 🎊)

Problem:
When scanning database results into struct fields with pointer types, zero values (0, false, empty string) were not being properly distinguished from NULL values. This caused nil pointers to be set to zero values incorrectly.

Solution:
Enhanced the getValueInterface function to properly initialize nil pointers before scanning, ensuring the SQL driver can correctly populate them with zero or non-zero values.

Code Changes:
```
func getValueInterface(value reflect.Value) (any, error) {
    if !value.CanAddr() || !value.Addr().CanInterface() {
        return nil, ErrNotReadableValue
    }

    // Initialize nil pointer before scanning
    if value.Kind() == reflect.Pointer && value.IsNil() {
        baseValueType := mapping.Deref(value.Type())
        value.Set(reflect.New(baseValueType))
    }

    return value.Addr().Interface(), nil
}
```
Impact:
```
type User struct {
    Name    string   `db:"name"`      // Always set
    Age     *int     `db:"age"`       // Can distinguish NULL vs 0
    Active  *bool    `db:"active"`    // Can distinguish NULL vs false
}

// Before: age=0 and age=NULL both resulted in nil pointer
// After:  age=0 → *int(0), age=NULL → nil pointer ✓
```
Benefits:
- Correct handling of NULL vs zero values
- Better semantic representation of optional fields
- Prevents unexpected nil pointer dereferences
- Aligns with Go's SQL scanning best practices
🔄 Breaking Changes (With Backward Compatibility)

Changed NonBlock Default to True (#5259)

Contributor: @kevwan

Motivation:
Aligned with gRPC official best practices which discourage blocking dials.

Change:
```
// zrpc/config.go
type RpcClientConf struct {
    // Before: NonBlock bool `json:",optional"`
    // After:
    NonBlock bool `json:",default=true"`  // Now defaults to true
}
```
Why This Matters:
1. Blocking dials are deprecated: grpc.WithBlock() is an anti-pattern
2. Connection state is dynamic: Being connected at dial time doesn't guarantee future connectivity
3. RPCs handle waiting: All RPCs automatically wait until connection or deadline
4. Simpler code: No need to check "ready" state before making calls
Migration Guide:

For most users, no action required - the new default is the recommended behavior.

If you explicitly need blocking behavior (not recommended):
```
// Option 1: Configuration
c := zrpc.RpcClientConf{
    NonBlock: false,  // Explicit blocking
}

// Option 2: Client option (deprecated)
client := zrpc.MustNewClient(c, zrpc.WithBlock())
```
Backward Compatibility:
- Existing configs with NonBlock: false continue to work
- New WithBlock() option available (marked deprecated)
- No changes needed for services already using NonBlock: true
Documentation:
See GRPC_NONBLOCK_CHANGE.md for detailed migration guide and rationale.
