history
Project history and usage
wandio is a small C I/O library from the Libtrace team for reading and writing files with transparent compression and optional background-thread compression or decompression. It is best understood as infrastructure below packet-trace tooling rather than as an end-user archive program.
Project history
The Libtrace project is a packet-trace capture and processing library associated with the University of Waikato's networking research ecosystem. wandio supplies the compressed and remote file I/O layer used by that family of tools, letting trace-oriented programs read gzip, bzip2, lzma, zstd, lz4, HTTP, and other streams through one API when the relevant libraries are available.
The release history shows maintenance around compression formats, HTTP behavior, and correctness. The 4.1.0 release in February 2019 added features around Swift reading and related contributions, 4.2.x releases fixed lz4, bzip2, HTTP, and suffix-based compression detection behavior, and 4.2.7-1 in June 2026 fixed zstd/lz4 length checking.
How it is used
wandio is used by developers who need libtrace-style file input and output without special-casing each compression container. The included `wandiocat` utility exposes that layer from the command line, but the main value is the C library API for programs that process large trace files and want streaming decompression or compression offloaded to another thread.
Why package nerds care
Its package significance is niche but real: it packages a reusable piece of systems plumbing from the packet-trace world. Instead of each trace-processing tool learning every compression library and remote-reader detail, wandio centralizes that behavior behind a small LGPL-licensed library.
