From 778cb72c8a0902bd0b8159ebd3bb7eff93f28c83 Mon Sep 17 00:00:00 2001 From: grm Date: Mon, 14 Sep 2026 23:51:55 +0300 Subject: Turn the image library into a file library, with a per-blog upload limit Bloggers want to attach PDFs, archives, audio and other files to posts, not only images. The Images tab becomes Files: any type is accepted, listed by kind with search, paging, rename and multi-file upload, and the editor's paste/drop/"Insert file" takes anything (images are shown, everything else becomes a link). The default limit goes from 5 to 10 MB and the superadmin can override it per blog from /admin/. Files stay in Postgres so one pg_dump is still the whole blog. The bytea column is STORAGE EXTERNAL and /media streams it in substring() slices, so serving never holds a whole file in memory whatever limit a blog gets. Serving any type on the root domain, which carries the session cookie, needs a policy: uploads are typed by sniffing (the extension may only refine a generic sniff to an allowlisted type) and only images, PDF, plain text, audio and video render inline; HTML, SVG, XML, scripts, archives and binaries always go out as application/octet-stream with Content-Disposition: attachment. The body cap moves out of requireAuth into guardPOST, which runs after withBlog has resolved the blog and so knows its limit.
