From Local Disk to SeaweedFS: Bypassing a GoToSocial Fileserver Bug with Self-Hosted S3 Storage

Tue, 18 Aug 2026 13:00:00 +0200

GoToSocial had a bug serving 0-byte images. I could have patched Go source code. Instead, I bypassed the entire fileserver and offloaded 92,000 files to SeaweedFS. Sometimes the best fix is an architecture pivot, not a code change.

The Problem

GoToSocial v0.22.1 has a confirmed bug where it uses mmap to serve media. On certain configs, this produces EINVAL errors during close(), resulting in HTTP 200 responses with 0-byte bodies. Caddy logs unexpected EOF because the connection drops mid-stream. The bug doesn’t care whether the file exists — the codepath itself is broken.

TL;DR Unix geek tries Windows 10 for a year. For the most part it works, but lots of growing pains. Going back to the land of GNU.

Introduction

A year ago, I started an attempt to give Windows another try. I jump around different platforms to stay current and cognisant of the industry shifts professionally. The need to get back to Windows happen to coincide with need for a new laptop.
