Package spew implements a deep pretty printer for Go data structures to aid in debugging.

A quick overview of the additional features spew provides over the built-in printing facilities for Go data types are as follows:

• Pointers are dereferenced and followed.

• Circular data structures are detected and handled properly.

• Custom Stringer/error interfaces are optionally invoked, including on unexported types.

• Custom types which only implement the Stringer/error interfaces via a pointer receiver are optionally invoked when passing non-pointer variables.

• Byte arrays and slices are dumped like the hexdump -C command which includes offsets, byte values in hex, and ASCII output (only when using Dump style).

Package poller is a file-descriptor multiplexer. It allows concurrent Read and Write operations from and to multiple file-descriptors without allocating one OS thread for every blocked operation. It operates similarly to Go's netpoller (which multiplexes network connections) without requiring special support from the Go runtime. It can be used with tty devices, character devices, pipes, FIFOs, and any file-descriptor that is poll-able, can be used with select(2), epoll(7), etc.

In addition, package poller allows the user to set timeouts (deadlines) for read and write operations, and also allows for safe cancellation of blocked read and write operations; a Close from another go-routine safely cancels ongoing (blocked) read and write operations.

It's an active fork of https://github.com/npat-efault/poller.

This package provides smooth, resilient, ordered, error-checked and anonymous delivery of streams over UDP packets. Features:

• designed for latency-sensitive scenarios

• cache-friendly and memory-optimized design

• handles >5K concurrent connections on a single commodity server

• compatible with net.Conn and net.Listener, serving as a drop-in replacement for net.TCPConn

• Forward Error Correction support with Reed-Solomon Codes

• packet-level encryption support with 3DES, AES, Blowfish, Cast5, PBKDF2, SM4, Salsa20, TEA, Twofish, and XTEA

• only a fixed number of goroutines are created for the entire server application

• compatible with skywind3000's C version with various improvements
