## プロジェクトの歴史と使われ方
libeatmydata is Stewart Smith's LD_PRELOAD library and `eatmydata` wrapper that deliberately turns durability operations such as fsync and O_SYNC into no-ops to make disposable test or build workloads faster.
### プロジェクトの歴史
The project page describes libeatmydata as a small LD_PRELOAD library, warns users not to use it where stored data matters, and notes a migration from an old Bazaar repository to GitHub. The GitHub README ties the project to Smith's linux.conf.au 2007 talk, 'Eat My Data: How Everybody gets File IO Wrong,' and says the talk covered common mistakes in POSIX file I/O.
The GitHub tags show historical releases libeatmydata-65 in September 2012, libeatmydata-82 in June 2013, libeatmydata-105 in November 2016, then v129 in April 2021, v130 in October 2021, and v131 in January 2023. The v130 release added a `syncfs()` wrapper, and v131 included macOS build and test fixes.
### 採用の歴史
The official page notes that most Linux distributions package libeatmydata as `eatmydata`, and the README gives Debian/Ubuntu installation as `apt install eatmydata`. Its adoption is strongest in test suites, package builds, and other repeatable workloads where crash safety is intentionally traded away for speed.
### 使われ方
The normal usage is intentionally tiny: install the package and run `eatmydata foo`. The README and project page both stress the safety boundary: use it for testing or disposable work, not for programs whose on-disk data you care about.
### パッケージ好きにとっての重要性
libeatmydata is beloved package-nerd plumbing because it names the tradeoff honestly and exposes it as one wrapper command. It is especially useful for distribution builders and database test runners who understand that avoiding fsync is unsafe for production but valuable in controlled, throwaway environments.
### タイムライン
- 2007: Project originated from Stewart Smith's linux.conf.au talk on POSIX file I/O mistakes.
- 2012: libeatmydata-65 tag published.
- 2013: libeatmydata-82 tag published.
- 2016: libeatmydata-105 tag published.
- 2021: v129 and v130 releases published; v130 added syncfs wrapping.
- 2023: v131 release published with small fixes including macOS build and test work.
### Related projects
- The project history references Bazaar, Launchpad, GitHub, Linux distribution packages named `eatmydata`, MySQL test-suite usage, and the POSIX file I/O APIs that the preload library intercepts.
