From 9d77f332d45861a9cae97d519656b8b957c00db2 Mon Sep 17 00:00:00 2001 From: Katharina Przybill <30441792+kathap@users.noreply.github.com> Date: Fri, 13 Mar 2026 15:59:13 +0100 Subject: [PATCH 01/23] Refactor DAV client, add missing operations **Added Missing Operations:** - COPY - Server-side blob copying via WebDAV COPY method - PROPERTIES - Retrieve blob metadata (ContentLength, ETag, LastModified) - ENSURE-STORAGE-EXISTS - Initialize WebDAV directory structure - SIGN - Generate pre-signed URLs with HMAC-SHA256 - DELETE-RECURSIVE - Delete all blobs matching a prefix **Structural Changes:** - Split into two-layer architecture like other providers (S3, Azure, etc.) - client.go: High-level DavBlobstore implementing storage.Storager interface -

The signer now combines: - Path prefix (/signed/, /read/, or /write/) - Endpoint base path (directory key from config) - Blob ID with hash prefix This ensures storage-cli and fog/webdav clients store blobs at identical physical locations for backward compatibility.
