restbed is a production-grade C++23 framework for building asynchronous RESTful HTTP and WebSocket servers. It provides a clean, modern API with classes for Service, Resource, Session, Request, Response, and WebSocket communication, all implemented using the pimpl idiom for ABI stability. The framework handles HTTP/1.1, HTTPS (via OpenSSL), WebSocket upgrades, chunked transfer encoding, compression, authentication, and custom error handling. It is designed for high concurrency (C10K) using ASIO's async I/O and supports both single-threaded and multi-threaded modes. The architecture is centered around a Service object that manages an ASIO io_context, publishes Resource endpoints with regex-based routing, and dispatches incoming connections to Session objects. Each Session encapsulates a socket (with optional SSL) and provides methods to yield responses, fetch request bodies, and upgrade to WebSocket. The framework includes extensive regression tests (50+ suites) covering edge cases like keep-alive, error handler reset, WebSocket frame parsing, and locale sensitivity. Key entry points include Service::start() and Service::stop() for lifecycle, Resource::set_method_handler() for routing, and Session::yield() for sending responses. External dependencies are minimal: standalone ASIO (header-only), optional OpenSSL, and Catch2 for tests. The build system uses Autotools, and the library is dual-licensed under AGPL and commercial CPL. Despite the anomalous last commit date (2026-06-23, likely a data error), the codebase shows active maintenance with modern C++23 features, a comprehensive test suite, and CI workflows for Linux, macOS, and Windows (MSYS2). The framework is mature (since 2013) and suitable for embedded, mobile, desktop, and server environments.
WePush is a Java application monorepo with two coexisting generations of a multi-channel bulk messaging system. The legacy `src/main` tree is a Swing desktop client that manages accounts, message templates, recipient lists, tasks, and run history, and sends via WeChat (official accounts, mini programs, WeCom), SMS vendors, email, HTTP, DingTalk/Feishu bots, and carrier SMS protocols (CMPP/SMGP/SGIP/SMPP). It persists to SQLite through MyBatis and generates UI with IntelliJ GUI Designer forms. The `next/` tree is a modular, distributed push orchestration platform: a Spring Boot control plane (REST + gRPC), remote agents connected via an mTLS gRPC stream, a provider SPI with built-in HTTP, Aliyun SMS, SMTP, WeChat, and bot providers, and pluggable signed PF4J plugins for carrier protocols. It adds multi-tenant workspaces, secret envelope encryption, artifact storage (local/S3), audience streaming import, run state machines with idempotency and retry, schedule management, a React/Vite web UI, an Electron desktop shell, and a Java SDK. Persistence is SQLite for standalone mode or PostgreSQL for server mode, with Flyway migrations and JDBC repositories. The Next codebase is well-architected with core-api/engine/provider-spi/service/domain/infrastructure separation, ADRs, architecture tests, integration tests, CI, and installers. However, the repository as a whole carries the legacy desktop codebase in parallel, duplicating several domain concepts and retaining generated UI code and older dependencies. This split and the aging legacy portions are the main sources of technical debt.
This repository contains a collection of example applications demonstrating the use of the gnet networking library in Go. The examples cover various networking paradigms including TCP, UDP, Unix domain sockets, HTTP, WebSocket, and a custom binary protocol. Each example is a standalone program showcasing event-driven connection handling, message parsing, and protocol implementation using gnet's APIs. Key examples include echo servers for different transports, an HTTP server using wildcat for parsing, a push server broadcasting periodic messages, a simple protocol client/server with a custom framing codec, and WebSocket implementations using both gobwas/ws and a custom RFC 6455-compliant codec. The code illustrates gnet's event loop patterns, connection context usage, and efficient I/O handling. While the examples are generally idiomatic and functional, some dependencies show mild technical drift (e.g., the wildcat HTTP parser is outdated). The repository is actively maintained with recent commits and serves as a practical reference for learning gnet-based network programming in Go.
