Fastzip is an opinionated Zip archiver and extractor with a focus on speed. Features:

• archiving and extraction of files and directories can only occur within a specified directory

• permissions, ownership (uid, gid on linux/unix) and modification times are preserved

• buffers used for copying files are recycled to reduce allocations

• files are archived and extracted concurrently

• by default, github.com/klauspost/compress/flate library is used for compression and decompression

Puddle is a tiny generic resource pool library hat uses the standard context library to signal cancellation of acquires. It is designed to contain the minimum functionality required for a resource pool. It can be used directly or it can be used as the base for a domain specific resource pool. For example, a database connection pool may use puddle internally and implement health checks and keep-alive behavior without needing to implement any concurrent code of its own.

Yamux (Yet another Multiplexer) relies on an underlying connection to provide reliability and ordering, such as TCP or Unix domain sockets, and provides stream-oriented multiplexing. It is inspired by SPDY but is not interoperable with it.

Features:

• streams can be opened by either client or server

• useful for nat traversal

• server-side push support

• avoid starvation

• back-pressure to prevent overwhelming a receiver

• enables persistent connections over a load balancer

• enables thousands of logical streams with low overhead

This library will help you allow two parties to generate a mutual secret key by using a weak key that is known to both beforehand (e.g. via some other channel of communication). This is a simple API for an implementation of password-authenticated key exchange (PAKE). This protocol is derived from Dan Boneh and Victor Shoup's cryptography book (pg 789, "PAKE2 protocol). I decided to create this library so I could use PAKE in my file-transfer utility, croc.

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 concurent 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 cancelation of blocked read and write operations; a Close from another go-routine safely cancels ongoing (blocked) read and write operations.

Proj is a selective and on-going port of the venerable PROJ.4 project to the Go language.

This package provides the following subpackages:

• proj (top-level): the Conversion API

• proj/cmd/proj: the simple proj command-line tool

• proj/core: the Core API, representing coordinate systems and conversion operations

• proj/gie: a naive implementation of the PROJ.4 gie tool, plus the full set of PROJ.4 test case files

• proj/merror: a little error package

• proj/mlog: a little logging package

• proj/operations: the actual coordinate operations; these routines tend to be closest to the original C code

• proj/support: misc structs and functions in support of the core package
