历史
项目历史与用法
libfaketime is a preload-based library and faketime wrapper that makes selected programs see modified dates and times without changing the system clock. It is packaged as a developer/testing utility because it exercises time-sensitive code at the process boundary.
项目历史
The project's NEWS file tracks changes back to version 0.1, beginning with fixes around time(NULL) and growing through clock_gettime interception, wrapper scripts, fractional offsets, speed changes, system-wide faketimerc files, macOS support, pthread-aware builds, deterministic time, and deterministic getrandom support.
Starting with libfaketime 0.9.5, the developer README says development and issue handling moved completely to GitHub, with official releases tagged there.
采用历史
Package managers adopted libfaketime because it solves a practical test problem: run one process under a fake clock while leaving the host clock alone. The README names deterministic builds, expired-certificate debugging, and year-2038 testing as intended use cases.
使用方式
Most users run the faketime wrapper or set preload-related environment variables directly. The README also documents important limits: statically linked and setuid binaries are not covered by the preload mechanism, some Java/JVM cases need monotonic-clock care, and programs that dynamically load timing libraries can bypass interception.
为什么软件包爱好者会关心
libfaketime is beloved packaging glue because it gives build systems and test suites a cheap fake clock without patching application code. That makes it useful for reproducible builds, certificate-expiry tests, date rollover tests, and awkward legacy software checks.
时间线
- 0.1: NEWS records initial fixes around time(NULL).
- 0.2: NEWS records clock_gettime interception.
- 0.7: NEWS records the wrapper shell script and man page.
- 0.9.5: Developer README records GitHub as the development and issue-handling home.
- 2025-06: README identifies version 0.9.12 and NEWS records improved macOS compatibility.
