- Add SaveMetaFn callback pattern: meta plugins receive a closure instead of
&Connection, enabling the same plugin code to work in local, client, and
server contexts (collect-to-Vec, collect-to-HashMap, or direct DB write)
- Client save now runs meta plugins locally during streaming (smart client
sets meta=false, server skips its own plugins)
- Add POST /api/item/{id}/update endpoint for re-running plugins on stored
content without downloading compressed data
- Add client update mode (--update with --meta-plugin flags)
- Extract shared utilities: stream_copy, print_serialized, build_path_table,
ensure_default_tag to reduce duplication across modes
- Add upsert_tag for idempotent tag addition (INSERT OR IGNORE)
- Add warn logging on save_meta lock failure in BaseMetaPlugin and MetaService
Plumb metadata filter from client CLI through the HTTP API to the
server's data_service.list_items(). The server accepts a JSON-encoded
meta query parameter where null values mean 'key exists' and string
values mean 'exact match'.
Also fix LZ4 compression round-trip for client mode:
- Explicit flush FrameEncoder before drop to avoid sending only the
frame header when compress=false
- Send _client_compression metadata so client knows actual compression
on retrieval (server records compression=None when compress=false)
- Use FrameDecoder (frame format) instead of decompress_size_prepended
(size-prepended format) to match server storage format
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.
Add server-side JWT authentication with permission-based access control
(read/write/delete claims). Password authentication now uses HTTP Basic
auth only (replacing Bearer). Add configurable username for both server
and client (--server-username/--client-username, defaults to "keep").
JWT secret supports file-based loading via --server-jwt-secret-file for
Docker secrets. OPTIONS preflight requests bypass auth. HEAD mapped to
read permission.

Add client mode enabling the keep CLI to connect to a remote keep
server over HTTP. Local plugins (compression, meta, filters) run on
the client; the server stores/retrieves binary blobs.
Architecture:
- Client save uses 3-thread streaming pipeline: reader thread (stdin
→ tee/stdout → hash → compress), OS pipe, streamer thread (pipe →
chunked HTTP POST). Memory usage is O(PIPESIZE) regardless of data
size.
- Server accepts compress=false, meta=false, decompress=false query
params for granular control of server-side processing.
- Streaming body handling on server via async channel → sync reader
bridge (ChannelReader).
Key additions:
- src/client.rs: KeepClient with post_stream() for chunked upload
- src/modes/client/: save, get, list, info, delete, diff, status
- --client-url / KEEP_CLIENT_URL configuration
- --client-password / KEEP_CLIENT_PASSWORD for auth
- os_pipe dependency for zero-copy pipe streaming
