Major overhaul of server architecture and security posture:
- Streaming: Unified all I/O through PIPESIZE (8192-byte) buffers.
POST bodies stream via MpscReader through the save pipeline. GET
content streams from disk via decompression to client. Removed
save_item_with_reader, get_item_content_info, ChannelReader.
413 responses keep partial items (nonfatal by design).
- Security: XSS protection in all HTML pages via html_escape crate.
Security headers middleware (nosniff, frame deny, referrer policy).
CORS tightened to explicit headers. Input validation for tags
(256 chars), metadata (128/4096), pagination (10k cap). Config
file reads use from_utf8_lossy. Generic error messages in HTML.
Diff endpoint has 10 MB per-item cap. max_body_size config option.
- Panics eliminated: Path unwraps → proper error propagation.
Mutex unwraps → map_err (registries) / expect with message (local).
- MCP removed: Deleted all MCP code, rmcp dependency, mcp feature.
- Docs: Updated README, DESIGN, AGENTS to reflect all changes.
Security:
- Use constant-time password comparison (subtle crate) to prevent timing attacks
- Replace permissive CORS with configurable origin-restricted CORS
- Add TLS warning when password auth is used without HTTPS
Bug fixes:
- Convert MetaPlugin panics to anyhow::Result (get_meta_plugin, outputs_mut, options_mut)
- Replace item.id.unwrap() with proper error handling across 15 call sites
- Fix panic on unknown column type in list mode
- Fix conflicting PIPESIZE constant (was 8192 vs 65536, now unified to 8192)
- Add 256MB filter chain buffer limit to prevent OOM
- Gracefully skip unregistered plugins instead of panicking
Dead code removal:
- Delete unused filter parser files (filter_parser.rs, filter.pest, parser/ module)
- ~260 lines of dead PEG parser code removed
Code consolidation:
- Add is_content_binary_from_metadata() helper (was duplicated in 4 places)
- Simplify save_item_raw() to delegate to save_item_raw_streaming() (~90 lines removed)
Incomplete features:
- Populate filter_plugins in status output from global registry
- Add FallbackMagicFileMetaPlugin (was referenced but never implemented)
- Document init_plugins() as intentional no-op
Infrastructure:
- Add Dockerfile (static musl binary on scratch, 4.8MB)
- Add .dockerignore
- Add cors_origin to ServerConfig and config.rs
