history

Project history and usage

libdeflate is Eric Biggers' optimized C library for whole-buffer DEFLATE, zlib, and gzip compression and decompression. It is intentionally not a streaming zlib clone; it trades API compatibility for speed, compactness, and easy embedding.

Project history

The README presents libdeflate as a fast whole-buffer compression library supporting raw DEFLATE, zlib-wrapped DEFLATE, and gzip-wrapped DEFLATE. It includes library APIs plus libdeflate-gzip/libdeflate-gunzip convenience programs, benchmarks, and checksum tools.

The NEWS file starts with version 0.1 as the initial official release, then records a steady sequence of compression-ratio, checksum, architecture, build, and portability improvements. Notable milestones include MIT relicensing by 0.5, CMake and compiler support work, custom allocator APIs in 1.19, RISC-V basics and new checksum acceleration in 1.20, and relocatable CMake package work in 1.25.

Adoption history

libdeflate became attractive anywhere software needed faster in-memory DEFLATE-family compression than zlib-style streaming APIs. The README explicitly supports direct source integration and documents language bindings, helping it spread into applications, libraries, and package managers as a performance-oriented dependency.

How it is used

Developers use libdeflate when the compressed or decompressed data fits in memory and whole-buffer APIs are acceptable. The libdeflate-gzip tool can substitute for standard gzip in some cases, but upstream warns it is a convenience program with limitations rather than the main use case.

Why package nerds care

libdeflate is a modern compression-library package with exactly the kind of constraints packagers care about: stable C APIs, CPU-specific optimized code selected at runtime, direct embedding support, CMake/pkg-config integration, and a non-zlib-compatible API that prevents accidental semantic confusion.

Timeline

  • 2016: The author publicly announced libdeflate as a new optimized DEFLATE implementation.
  • 2017: Version 0.1 was the initial official release according to upstream NEWS.
  • 2018: Version 1.0-era Windows binary and API usage surfaced in upstream issue and release workflows.
  • 2023: Version 1.19 added custom allocator APIs and compatibility fixes for DEFLATE streams created by libdeflate.
  • 2024: Version 1.20 added VPCLMULQDQ/VNNI checksum acceleration and basic RISC-V optimizations.
  • 2026: Version 1.25 fixed a GCC 16 build error and made the CMake package relocatable.

Related projects

  • zlib, gzip, and raw DEFLATE are the formats and incumbent ecosystem around libdeflate. Language bindings and bundled integrations use libdeflate when whole-buffer compression is a better fit than streaming APIs.
