Reproduce the Reporter's Container Before You Patch an OSS Bug

说明与用途

逐步构建可重现容器，验证错误，应用最小补丁，并向维护者交付可验证的证据包。

问题

Open‑source patches are often rejected because the maintainer cannot reproduce the bug in the reporter’s environment.

结果

The workflow yields a reproducible, verifiable evidence bundle that eliminates guesswork, reduces patch rejection, and speeds up maintainer review.

工作流

• Capture the environment ledger from the issue text into a JSON file.
• Bake a reproducer Docker image using the ledger, pinning the runtime version and recording the image digest.
• Run the reproducer script to confirm the bug reproduces (exit 0) and save the output as before.log.
• Apply the smallest diff to the source, then re‑run the same script to ensure it now exits 1 and logs NO_CRASH in after.log.
• Package env‑ledger.json, image‑digest.txt, before.log, after.log, the unified diff, and the reproducer script into a bundle, hash it, and provide it to the reviewer.

证据

Most rejected open-source patches fail for a boring reason. The bug was never reproduced on the reporter's environment.

来源

The loop is: capture an environment ledger, bake a reproducer container, require a failing exit code, patch the smallest diff, then re-run the same script.

来源

The digest line belongs in the pull request body. A maintainer can rebuild the exact same image from it.
