Your Code Ran on the Free Box. That's Not an Environment Match.

说明与用途

fingerprint.sh 脚本捕获本地与免费 CI 环境的运行时信息，进行 diff，定位 GLIBC 版本、架构、语言环境和时区等差异，快速定位测试失败原因。

问题

Tests that pass locally fail on a CI free box due to environment differences such as GLIBC version, architecture, locale, and timezone.

结果

By capturing runtime facts and diffing them, developers can quickly isolate environment mismatches that cause CI failures, reducing debugging time.

工作流

• Run fingerprint.sh on local machine and save output to laptop.txt
• Run fingerprint.sh on the free runner via ssh and save to remote.txt
• Diff laptop.txt and remote.txt to identify differences
• Interpret diff using the decision table to determine cause and next step
• Apply corrective action such as rebuilding wheels or pinning versions
• Re-run tests to confirm resolution

证据

Your tests pass on your laptop. The same commit then dies on a plain Ubuntu box with error while loading shared libraries: GLIBC_2.34 not found.

来源

Run the same workload three times. If the spread is huge, you have contention.

来源

This prints facts, one per line. No dependencies beyond bash and coreutils.
