PCS I/O (Parallel Cloud Storage library)

Description

pcs_io is a C cross platform library implementing async event loop with coroutines, context and other features.

Features

1. Basic event loop APIs: timers, jobs, thread pool jobs etc.
2. Usage of native OS asynchronous APIs support: epoll, Windows IOCP, SUN ports, BSD kqueue, RDMA
3. Full memory usage accounting and wrapped malloc APIs
4. coroutines support with:
   • I/O blocking APIs for files, sockets, pipes, SSL sockets.
   • timeouts and I/O cancellation (via context)
   • contexts support similar to Golang
   • multi-threading support with Coroutines scheduler
   • coroutines waitqueues, mutexes etc.
5. simple config files API support
6. built-in cross platform getopt_long support
7. basic containers (RB tree, lists, heap)
8. Network address abstraction layer
9. internal scatter gather bufqueue and user pipes

Built-in debug features and capabilities

• Async compressed on the fly logging with GZIP/ZSTD support
• Address and thread sanitizer support
• Built-in profiler and watchdog monitoring event loop is really non-blocking (and catching kernel issues, swap out etc.)
• Memory accounting with detailed per-line reporting
• BUG_ON() assertions and call trace dumps on errors / crashes
