The Stdlib Ledger That Stops a Re-Run From Double-Posting Uploads

说明与用途

仅使用Python标准库的账本脚本跟踪已完成的上传，防止重复上传并实现安全重跑。

问题

Re-running an upload script can cause duplicate uploads, leading to spam flags and wasted time.

结果

The ledger prevented any double‑posting, eliminated spam flags, and provided auditability without adding dependencies.

工作流

• Run upload_tracker.py pending items.txt to list unfinished items
• Run upload_tracker.py done "asset-001.jpg" after each successful upload
• Run upload_tracker.py status to audit completed uploads
• Modify batch script to query ledger for pending items before uploading

证据

I nearly lost an upload account to a rerun. My batch script had already pushed 200 files to a stock site.

The fix was not a smarter uploader. It was a ledger.

来源

upload_tracker.py is about 40 lines of standard library Python, and it does one thing: it remembers what you have already posted.

来源

Once the tracker exists, the workflow changes shape. You do not run a batch from your asset folder. You run it from pending.

来源

That gives you three guarantees for free: Rerun safety, Resumability, Auditability.
