v0.16.1

Features

gRPC - Reuse Write Buffer per Connection (#1918)

gRPC (nphttp2) transport now supports reusing a write buffer for each connection, reducing per-frame allocations on the write path. New client and server options are exposed to enable this behavior.

• Framer refactor in pkg/remote/trans/nphttp2/grpc/framer.go to share a buffer across writes on the same connection.
• New options in client/option.go and server/option.go to opt into buffer reuse.

Optimizations

ttstream - Remove Connection Write Goroutine to Avoid Sender OOM (#1917)

Removed the dedicated per-connection write goroutine from the ttstream transport. The previous design could accumulate unbounded buffered frames on the sender side when the peer was slow, leading to out-of-memory on the sender. Writes are now performed synchronously, applying natural back-pressure to producers.

• Refactored pkg/remote/trans/ttstream/transport_client.go and transport_server.go to drop the writer goroutine.
• Added frame-level tests and expanded transport test coverage.

v0.16.0

Features

Streaming - Recv Timeout and gRPC Error/Log Adjustments (#1911)

Added a new Recv timeout configuration for streaming RPCs, allowing users to control how long a single Recv call may block before returning an error. Also refined gRPC error propagation and logging behavior so streaming failures are reported more accurately.

• New call option in client/callopt/streamcall and client option in client/option_stream.go for configuring Recv timeout.
• Adjustments to pkg/remote/trans/nphttp2 codes and pkg/remote/trans/ttstream exceptions for clearer error classification.

Streaming - Detailed Tracing Events (#1905)

Introduced fine-grained tracing events for streaming RPCs. A new stream_tracer in pkg/rpcinfo enables observability into per-stream lifecycle events (send/recv/header/trailer), and both gRPC (nphttp2) and ttstream transports now emit these events.

• New pkg/rpcinfo/stream_tracer.go with extensive test coverage.
• New stream option APIs on both client and server (client/option_stream.go, server/option_stream.go).

Streaming - Remove RPCInfo Reuse for Streaming (#1909)

Removed RPCInfo object reuse on the streaming server path for both nphttp2 and ttstream. This avoids cross-stream state leakage where a long-lived stream could observe stale data from a previously recycled RPCInfo.

Bug Fixes

Code Generation - DeepCopy for Binary Types (#1902)

1. Fixed: DeepCopy code generation now correctly handles Thrift binary types that are mapped to Go string types.

This ensures string-typed binary fields are handled with simple value assignment instead of byte slice allocation and copying.

Dependencies

Updated: github.com/cloudwego/gopkg v0.1.6 → v0.1.8 (#1903)

Changes included from gopkg v0.1.7:

• Optimized thrift span cache with lazy initialization (performance improvement)
• Fixed protocol handling to ensure data length matches copied bytes for strings and binary data (correctness fix)
• Added connection state checker for gonet (stability improvement)
• Resolved file descriptor operator memory leak (memory safety)

Changes included from gopkg v0.1.8:

• Increased ttheader limit size from 64KB to 256KB
• Fixed header length overflow issues

Impact: Improves protocol handling correctness, memory safety, and increases header size limits for TTHeader protocol users.

Commits

• ccdabb2 - fix(tool): DeepCopy assignment failed when map key type is binary (#1902)
• 3f27dca - chore: update github.com/cloudwego/gopkg from v0.1.6 to v0.1.8 (#1903)
