Gemini API contents format (~/.gemini/sessions/*.json): {"contents": [{"role": "user", "parts": [{"text": "..."}]}, ...]} 2. Messages-wrapper variant: {"messages": [{"role": "user", ...}, {"role": "model", ...}]} 3. Flat top-level list with role="model". This complements the existing _try_gemini_jsonl parser (which handles ~/.gemini/tmp//chats/session-*.jsonl with session_metadata sentinel) — JSONL covers Gemini CLI runtime sessions, JSON covers exported / Studio-saved transcripts. ## Review feedback addressed (PR #204) bgauryy review: - #1 Parser-precedence bug: _try_gemini_json runs *before* _try_claude_ai_json so the {"messages":[..., role=model, ...]} layout is no longer silently claimed by the Claude parser. The Gemini parser's has_model_role guard prevents false-positives against Claude / ChatGPT data. - #2 Layout 2a coverage: TestGeminiJson.test_messages_wrapper_format + test_messages_wrapper_does_not_get_claimed_by_claude pin the fix in place. - #3 Test conflicts with current main: rebased onto develop; tests restructured into TestGeminiJson class. - #4 tempfile/os.unlink → pytest tmp_path everywhere. - #5 elif not text → else (the elif branch was dead). - #6 Module docstring updated to mention Google AI Studio.

007/149] feat: add Cursor IDE support (hooks, plugin, skill, docs, tests) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds first-class Cursor IDE integration alongside the existing Claude Code and Codex hook flows, so Cursor users get the same automatic diary saves, pre-compaction transcript capture, and session-start memory recall — without changing any default behaviour for existing users. What's included --------------- Cursor hook scripts (hooks/cursor/): - mempal_save_hook_cursor.sh — Stop event, counter + loop_count guard, pending-save marker consumption, background mempalace mine, followup_message emission. - mempal_precompact_hook_cursor.sh — synchronous mine before compaction, drops a pending_save marker, returns user_message. - mempal_wake_hook_cursor.sh — sessionStart event, wing-scoped recall guidance via additional_context. - lib/common.sh — shared parsing + state helpers (bash 3.2 safe, no heredoc-in-subshell traps). - install.sh — idempotent installer with --scope, --variant, --dry-run, --uninstall. Recognises existing entries by basename so re-installs across paths work. - STDIN_SHAPE.md, README.md — payload schemas + quick reference. Cursor plugin (.cursor-plugin/ + repo-root components): - plugin.json, marketplace.json, README.md. - skills/mempalace/SKILL.md — model-invocable skill mirroring the Claude plugin's skill surface. - commands/mempalace-{help,init,mine,search,status}.md — slash commands for marketplace-published installs (filename = slug). - mcp.json — auto-registers the mempalace MCP server, wrapped under the documented mcpServers key. Examples + docs: - examples/cursor/hooks.json, hooks.minimal.json + README. - website/guide/cursor-hooks.md + sidebar entry. - README.md and CHANGELOG.md updates. Tests (129 new, all green): - tests/test_cursor_hooks_shell.py — 75 behavioural tests for the three hook scripts: kill switches, input parsing, counter logic, loop prevention, pending markers, wing inference, logging. - tests/test_cursor_hooks_install.py — 19 contract tests for the installer: dry-run, idempotent merge, basename-matched uninstall, refusal to overwrite malformed JSON. - tests/test_cursor_plugin_manifest.py — 35 contract tests for the plugin: manifest validity, version sync with mempalace.version, mcp.json shape, skill/command frontmatter, default-discovery layout invariants. Design notes ------------ - Local-first and zero-API by default; hooks never call external services. Same privacy model as the existing Claude Code hooks. - Fail-open: hook scripts deliberately do not use set -e so a broken hook can never block the user's conversation. - Cursor preCompact cannot block + return a followup, so we synchronously mine the transcript and drop a pending_save marker that the next stop hook consumes — guarantees verbatim capture before context window compression. - Cursor's default plugin discovery requires real commands/, skills/, and mcp.json at the plugin root (verified against the cached cloudflare plugin); .cursor-plugin/{commands,skills} are convenience symlinks back to those canonical locations. - bash 3.2 compatibility throughout: avoids heredoc-in-command- substitution parser bugs; uses python -c for JSON parsing; basename-matched entry recognition in install.sh. - All changes are additive. No existing files are removed, no existing hooks change behaviour, and no new runtime dependencies are introduced.

Contract tests in [`tests/test_cursor_plugin_manifest.py`](tests/test_cursor_plugin_manifest.py) cover manifest JSON validity, kebab-case naming, `..`-free relative paths, on-disk path resolution, marketplace alignment, MCP config shape (`mcpServers` wrapper required by Cursor, unlike Claude's flat `.mcp.json`), and every skill/command frontmatter — 32 tests, all pure file inspection so they run on any CI platform without Cursor itself. + +- **Cursor IDE hook support (`stop` / `preCompact` / `sessionStart`).** Three new bash hooks live under [`hooks/cursor/`](hooks/cursor/) and share a `lib/common.sh` helpers module. The save hook counts `stop` invocations per Cursor `conversation_id` and emits a `followup_message` every `MEMPAL_SAVE_INTERVAL` (default 15) so the agent files the session into MemPalace and writes a diary entry. The precompact hook synchronously mines the transcript before Cursor's compaction summarises it and drops a marker so the next `stop` forces a save nudge (Cursor's `preCompact` is observational-only — it cannot block or emit a `followup_message`, unlike Claude Code's `PreCompact`). The wake hook is Cursor-only: `sessionStart` returns `additional_context` telling the agent to recall scoped to the wing inferred from the workspace root. Honours the same `MEMPALACE_HOOKS_AUTO_SAVE=false` kill switch as the Claude Code hooks, plus a new `MEMPAL_DISABLE_HOOK=1` alias and a `MEMPAL_STATE_DIR` env override. Includes an opt-in installer at [`hooks/cursor/install.sh`](hooks/cursor/install.sh) with `--scope user|project`, `--variant full|minimal`, `--dry-run`, and `--uninstall` (idempotent, preserves unrelated hooks via `python3`-based JSON merge — no `jq` dependency). Example wirings live at [`examples/cursor/hooks.json`](examples/cursor/hooks.json) and [`examples/cursor/hooks.minimal.json`](examples/cursor/hooks.minimal.json); they are intentionally not placed at the repo root because Cursor auto-loads project hooks from any trusted workspace and we do not arm hooks on contributor checkout.

Drops a pending-save marker so the next stop forces a save followup. | + +**Two-layer capture:** the save and precompact hooks both mine the JSONL +transcript directly into the palace (capturing verbatim tool output — Shell +results, search findings, build errors).

Re-running is idempotent.

If +hooks still do not fire, restart Cursor and check the Hooks panel in +Settings → Hooks. + +## Configuration + +All knobs are environment variables. Defaults match the Claude Code hooks +where they overlap. + +- **`MEMPAL_SAVE_INTERVAL=15`** — number of `stop` events between save + followups. Lower = more frequent saves, higher = less interruption. +- **`MEMPAL_STATE_DIR`** — where the hook keeps counter files, the + pending-save marker, and `cursor_hook.log`. Defaults to + `~/.mempalace/hook_state/`. +- **`MEMPAL_DIR`** — optional project directory (code, notes, docs) to + also mine on each save trigger, with `--mode projects`. The transcript + is always mined regardless — `MEMPAL_DIR` is purely additive. +- **`MEMPAL_PYTHON`** — path to a Python 3 interpreter.

Bug fixes (high) ---------------- 1. hooks/cursor/lib/common.sh — config.json kill-switch check used a `python3 - <<'PYEOF' ... PYEOF` heredoc inside a `$(...)` command substitution. The heredoc body contains parens which trips the macOS bash 3.2.57 parser bug. Replaced with a `python -c '...'` call passing the config path as argv[1]. Matches the pattern already used in mempal_parse_stdin in the same file. 2. hooks/cursor/install.sh — a relative `--install-dir` was written verbatim into hooks.json. Cursor invokes hook commands from its own working directory (typically the project root), so a relative command path would silently fail to launch the hook. Now resolved to an absolute path against `$PWD` before being baked in. 3. hooks/cursor/mempal_save_hook_cursor.sh — `MEMPAL_SAVE_INTERVAL=0` would crash bash on `$((NEXT % 0))` (division by zero). Extended the existing sanitiser case to coerce 0 to the default interval alongside empty / non-numeric values. Cleanups (medium) ----------------- 4. hooks/cursor/install.sh — the EMPTY_CHECK_PY temp file is now inlined as `python -c '...'`. Removes a small leak window (tmpfile would linger if the script were interrupted between mktemp and rm -f) and shortens the script. 5. hooks/cursor/install.sh — `mktemp -t prefix` has subtly different semantics on BSD (macOS) vs GNU mktemp. Switched to the portable absolute-template form `mktemp "${TMPDIR:-/tmp}/...XXXXXX"` which behaves identically on both. Regression tests ---------------- - tests/test_cursor_hooks_shell.py test_save_interval_zero_is_coerced_to_default — guards fix #3. - tests/test_cursor_hooks_install.py — new TestInstallDirAbsolutePath class: test_relative_install_dir_is_absolutized_in_hooks_json — guards fix #2 against regression. test_absolute_install_dir_is_preserved_verbatim — guards that the relative-to-absolute resolution does not mangle paths that were already absolute. Verification ------------ - bash -n on all three edited scripts: clean. - uv run pytest tests/test_cursor_hooks_*.py tests/test_cursor_plugin_manifest.py: 132 passed (was 129; +3 regression tests). - uv run pytest tests/ --ignore=tests/benchmarks: 2399 passed, 3 skipped (pre-existing). - uv run ruff check . / ruff format --check .: clean.

Cursor-only scope; cross-IDE items (wing-naming convention, shared-file merge order) are coordinated on the separate Antigravity branch. followup_message default (the one "decide before merge" item): - Keep the stop-hook followup ON by default. Cursor's transcript format is undocumented and mempalace/normalize.py has no Cursor parser, so the background `mempalace mine --mode convos` is best-effort only and does not yet yield clean verbatim drawers. The followup is therefore the load-bearing verbatim-capture path; defaulting it off would leave a default Cursor install capturing nothing. - Add an opt-out (MEMPAL_CURSOR_SILENT=1, or MEMPAL_VERBOSE=false) for users who want the Claude-style "zero tokens in chat" behaviour. The hook still mines and keeps its counters/markers when silenced. - Correct the misleading "background mine captures it" comments in the save and precompact hooks; update hooks/cursor/README.md and the guide. Hygiene fixes: - Drop the hardcoded "version" field from .cursor-plugin/plugin.json and marketplace.json (mempalace/version.py is the single source of truth); tests now assert the field stays absent. - Remove the committed .cursor-plugin/{commands,skills} symlinks (they break on Windows clones with core.symlinks=false and were redundant with the real repo-root components that `source: "."` already serves); add a guard test that no symlinks exist under .cursor-plugin/. - Document the preCompact synchronous-mine timeout tradeoff and that an incremental/append-only mine is recoverable if killed (no corruption). - Add a Cursor-namespaced, daily-throttled TTL sweep (MEMPAL_STATE_TTL_DAYS, default 30) to lib/common.sh that GCs stale cursor_*.count/.pending only, after the kill-switch check; shared logs and antigravity_* are untouched. Verification: full suite green (2424 passed, 3 skipped), ruff check + format clean, bash -n clean on all cursor scripts. +30 Cursor tests (followup opt-out, state GC, TTL validation, no-symlink/version guards).

The wake hook is Cursor-only: `sessionStart` returns `additional_context` telling the agent to recall scoped to the wing inferred from the workspace root. Honours the same `MEMPALACE_HOOKS_AUTO_SAVE=false` kill switch as the Claude Code hooks, plus a new `MEMPAL_DISABLE_HOOK=1` alias and a `MEMPAL_STATE_DIR` env override. Per-conversation state files are garbage-collected by a daily-throttled, Cursor-namespaced TTL sweep (`MEMPAL_STATE_TTL_DAYS`, default 30) so `cursor_*.count` / `cursor_*.pending` cannot grow unbounded — shared logs and other editors' state are never touched. Includes an opt-in installer at [`hooks/cursor/install.sh`](hooks/cursor/install.sh) with `--scope user|project`, `--variant full|minimal`, `--dry-run`, and `--uninstall` (idempotent, preserves unrelated hooks via `python3`-based JSON merge — no `jq` dependency). Example wirings live at [`examples/cursor/hooks.json`](examples/cursor/hooks.json) and [`examples/cursor/hooks.minimal.json`](examples/cursor/hooks.minimal.json); they are intentionally not placed at the repo root because Cursor auto-loads project hooks from any trusted workspace and we do not arm hooks on contributor checkout.

Since then 13 more agent-facing tools have landed; this PR documents the 8 that openclaw should expose so agents can call them natively instead of falling back to `npx mcporter call ...`: Search & Browse: - mempalace_list_drawers (paginated drawer listing) - mempalace_get_drawer (fetch a single drawer by id) Palace Graph: - mempalace_create_tunnel (explicit cross-wing link) - mempalace_list_tunnels (enumerate explicit tunnels) - mempalace_delete_tunnel (remove an explicit tunnel) - mempalace_follow_tunnels (walk explicit tunnels from a room) Write / Session: - mempalace_update_drawer (mutate content or relocate a drawer) - mempalace_memories_filed_away (ack the silent auto-save hook) The 3 admin-only tools (mempalace_sync, mempalace_hook_settings, mempalace_reconnect) are intentionally left out — they're host/admin operations, not agent-facing memory operations. The Hermes MemoryProvider plugin landing in MemPalace/mempalace#1684 makes the same call.

charset=UTF-8 Content-Transfer-Encoding: 8bit Pre-3.4 the hallway store was hardcoded at ~/.mempalace/hallways.json regardless of the configured palace_path, so two palaces on one host silently shared one file. Mining into palace-A leaked records into palace-B's hallway code paths. Apply the 3.3.6 tunnel-file migration pattern: * MempalaceConfig.hallway_file resolves to /hallways.json * hallways._get_hallway_file(config) reads through MempalaceConfig * hallways._legacy_hallway_file() exposes the pre-migration hardcoded path for one-time orphan detection; _load_hallways logs a one-line warning when the legacy file exists but the configured one doesn't, matching palace_graph._load_tunnels behavior. No auto-migration — silent merging risks clobbering newer data. Atomic-write + 0600 semantics unchanged. Module-level _HALLWAY_FILE constant kept and honored when monkey-patched directly, so the three existing test sites that patch it (test_hallways.py, test_hallways_pagination.py, test_mcp_server.py) keep working without modification. New coverage in tests/test_hallways_palace_scoped.py mirrors the analogous tunnel tests: resolver default + custom palace_path + env-var redirect, orphaned-legacy warning + no-warning when paths match, and an end-to-end multi-palace isolation regression guard.

Assertions are preserved (SystemExit code 1 → returncode 1; captured stdout substring → result.stdout). The child's entity registry (`~/.mempalace/known_entities.json`, resolved via expanduser at import) is redirected by overriding both HOME and USERPROFILE in the subprocess env so it works on POSIX and Windows. Verified: `pytest tests/test_fact_checker.py -W error::RuntimeWarning` passes (26) with the warning promoted to error — proving it no longer fires.

Bug fix — `date -r FILE` is GNU-only. On BSD/macOS `date -r` expects epoch seconds, not a path, so the staleness/throttle checks in the new Cursor and Antigravity hooks silently failed on macOS: the state GC swept on every fire and the pending-save guard was skipped. Replace with a portable `os.path.getmtime` one-liner via the already-resolved $MEMPAL_PYTHON_BIN (cursor/lib, antigravity/lib, antigravity save hook). This restores the "bash 3.2.57 / macOS default" compatibility the Antigravity changelog claims. Docs: - Correct the MCP tool count to 33 (was 19/29/31 in 21 places across plugin manifests, READMEs, and website docs — all drifted from the TOOLS dict / mcp-tools.md reference, which both have 33). - Fix broken CHANGELOG link to the Cursor skill (skills/, not .cursor-plugin/skills/). - Fix one-too-many `../` in skills/mempalace/SKILL.md's cursor-hooks link (resolved above the repo root). - Add the required `mcpServers` wrapper to the mcp.json example in .cursor-plugin/README.md so copy-paste yields a valid Cursor config. Left intentionally unchanged: the os.dup2 fd-1 redirect in mcp_server.py is deliberate (#225 keeps JSON-RPC off fd 1). --- .claude-plugin/README.md | 4 ++-- .claude-plugin/marketplace.json | 2 +- .claude-plugin/plugin.json | 2 +- .codex-plugin/README.md | 2 +- .codex-plugin/plugin.json | 4 ++-- .cursor-plugin/README.md | 10 ++++++---- .cursor-plugin/marketplace.json | 2 +- .cursor-plugin/plugin.json | 2 +- CHANGELOG.md | 2 +- README.md | 2 +- hooks/antigravity/lib/common.sh | 2 +- hooks/antigravity/mempal_save_hook_antigravity.sh | 4 ++-- hooks/cursor/lib/common.sh | 2 +- mempalace/README.md | 2 +- skills/mempalace/SKILL.md | 4 ++-- website/guide/claude-code.md | 2 +- website/guide/mcp-integration.md | 4 ++-- website/guide/openclaw.md | 2 +- website/reference/mcp-tools.md | 2 +- website/reference/modules.md | 4 ++-- 20 files changed, 31 insertions(+), 29 deletions(-) diff --git a/.claude-plugin/README.md b/.claude-plugin/README.md index b6708bb2b2..e9e6468e95 100644 --- a/.claude-plugin/README.md +++ b/.claude-plugin/README.md @@ -1,6 +1,6 @@ # MemPalace Claude Code Plugin -A Claude Code plugin that gives your AI a persistent memory system.

The plugin manifest deliberately omits a hardcoded `version` field — `mempalace/version.py` is the single source of truth, so there is nothing to drift on the next release (a contract test enforces the field stays absent).

The save hook counts `stop` invocations per Cursor `conversation_id` and emits a `followup_message` every `MEMPAL_SAVE_INTERVAL` (default 15) so the agent files the session into MemPalace and writes a diary entry. Unlike the silent-by-default Claude Code hook, the Cursor followup fires **on by default**: Cursor's transcript format is undocumented and `normalize.py` has no Cursor parser yet, so the background `mempalace mine --mode convos` is best-effort only and the `followup_message` is the load-bearing verbatim-capture path. Users who want the Claude-style "zero tokens in the chat window" behaviour can suppress it with `MEMPAL_CURSOR_SILENT=1` (or `MEMPAL_VERBOSE=false`); the default flips to silent once a Cursor transcript parser lands. The precompact hook synchronously mines the transcript before Cursor's compaction summarises it and drops a marker so the next `stop` forces a save nudge (Cursor's `preCompact` is observational-only — it cannot block or emit a `followup_message`, unlike Claude Code's `PreCompact`); the synchronous mine is bounded by Cursor's per-hook timeout, and because `mempalace mine` is incremental/append-only a killed mine resumes cleanly on the next run rather than corrupting the palace. The wake hook is Cursor-only: `sessionStart` returns `additional_context` telling the agent to recall scoped to the wing inferred from the workspace root. Honours the same `MEMPALACE_HOOKS_AUTO_SAVE=false` kill switch as the Claude Code hooks, plus a new `MEMPAL_DISABLE_HOOK=1` alias and a `MEMPAL_STATE_DIR` env override. Per-conversation state files are garbage-collected by a daily-throttled, Cursor-namespaced TTL sweep (`MEMPAL_STATE_TTL_DAYS`, default 30) so `cursor_*.count` / `cursor_*.pending` cannot grow unbounded — shared logs and other editors' state are never touched. Includes an opt-in installer at [`hooks/cursor/install.sh`](hooks/cursor/install.sh) with `--scope user|project`, `--variant full|minimal`, `--dry-run`, and `--uninstall` (idempotent, preserves unrelated hooks via `python3`-based JSON merge — no `jq` dependency). Example wirings live at [`examples/cursor/hooks.json`](examples/cursor/hooks.json) and [`examples/cursor/hooks.minimal.json`](examples/cursor/hooks.minimal.json); they are intentionally not placed at the repo root because Cursor auto-loads project hooks from any trusted workspace and we do not arm hooks on contributor checkout.

Strictly opt-in: no flag, env, or config means no daemon and no behavior change. - Hooks opt in via MEMPALACE_HOOKS_DAEMON or config hooks.daemon; when the daemon is not already running, hooks fall back to the existing direct/spawn path so the 500ms hook budget is preserved (hooks never auto-start the daemon). - service.run_sync renders the same operator-facing report shape as the direct CLI sync path (no_source, out_of_scope, by_source, Re-run/Removed hints) and drops the old KeyError-prone 'deleted' read. --- mempalace/cli.py | 214 +++++++- mempalace/config.py | 13 + mempalace/daemon.py

Root causes and fixes: - Linux 3.9 collection error: `_submit_daemon_job`'s `dedupe_key: str | None` parameter annotation is evaluated at def time, and hooks_cli.py has no `from __future__ import annotations` — `str | None` raises TypeError on 3.9. Reverted to `dedupe_key: str = None` (the original, 3.9-safe). The other `int | None` in the file is a function-local annotation, which is never evaluated, so it was never the problem. - macOS/Windows daemon lifecycle flakes: the 3 HTTP-lifecycle tests failed at the 10s readiness deadline on contended CI runners (localhost bind is sub-second locally but took ~5s when it passed on the macOS fleet, >10s when it didn't), and because the server thread never shuts down on timeout, run_server's `os.environ["MEMPALACE_PALACE_PATH"]` + `os.umask(0o077)` mutations leaked into the rest of the suite — poisoning every later test that reads MempalaceConfig().palace_path (the 60+ test_mcp_server cascade on macOS; the at-exit socket hang → SIGINT on Windows). Bumped the readiness deadline to 30s and added a module-scoped snapshot + autouse fixture in test_daemon.py that force-restores the env + umask to the pre-suite baseline after every daemon test, so a leaked server thread can't poison other test files. Gemini review comments (fixed in code, no thread replies per convention): - daemon.py `_connect()` was a bare `sqlite3.connect` whose `with`-block only managed the transaction, not the connection — an unbounded FD leak in a long-lived daemon running thousands of jobs (also the source of the Windows "unclosed database" ResourceWarning noise). Converted to a closing @contextlib.contextmanager. - `QueueStore.finish()` gained `only_if_running`; `_safe_finish` passes it so a late worker finish can't overwrite a shutdown-cancelled job back to succeeded/failed — removes the reliance on process-exit timing. - `DaemonClient.request` wraps the final `json.loads` in try/except JSONDecodeError → DaemonError, so a non-JSON 2xx response surfaces as a structured error instead of a bare JSONDecodeError. - test_sync.py: removed the module-level `import mempalace.mcp_server` and moved the stdout-rebinding side effect into an autouse fixture scoped to TestServiceRunSyncReport, so the embedder/Chroma import chain is no longer forced at collection time for the existing sync tests. Coverage: added focused happy-path tests for service.run_sync early-returns, run_mine backend application + invalid mode, execute_job kind dispatch, run_diary_write arg forwarding, run_mcp_tool write-tool dispatch, and print_job_result — lifts service.py from 57% to 85% so the new files (service 85%, daemon 80%) don't drag the total below the 80% CI gate now that the daemon tests complete and the gate is actually evaluated. --- mempalace/daemon.py | 47 +++++++-- mempalace/hooks_cli.py | 2 +- tests/test_daemon.py | 214 ++++++++++++++++++++++++++++++++++++++++- tests/test_sync.py | 18 ++-- 4 files changed, 266 insertions(+), 15 deletions(-) diff --git a/mempalace/daemon.py b/mempalace/daemon.py index d24e259616..3440bd0c0b 100644 --- a/mempalace/daemon.py +++ b/mempalace/daemon.py @@ -8,6 +8,7 @@ from __future__ import annotations import argparse +import contextlib import json import os import secrets @@ -173,10 +174,26 @@ def __init__(self, path: Path): self._lock = threading.RLock() self._init_db() + @contextlib.contextmanager def _connect(self): + """Open a short-lived sqlite3 connection and close it on exit. + + The bare ``with sqlite3.connect(...)`` context manager only manages the + transaction (commit/rollback) — it does NOT close the connection, so every + QueueStore call in this long-lived daemon process leaked a connection FD. + In a daemon that runs thousands of jobs that is an unbounded FD leak.

The daemon is always on 127.0.0.1, so a request must never go through an HTTP proxy — this is the correct production choice. It also bypasses urllib's proxy discovery (macOS _scproxy via SystemConfiguration), which runs on the first request to any host and is NOT bounded by the per-request timeout: on a CI runner with no network it hangs for tens of seconds, which looked exactly like the daemon never came up (test_daemon_http_lifecycle_executes_job timed out at 30.18s). With the no-proxy opener the lifecycle runs in 0.78s and no server thread is leaked — which also removes the timing skew that made the sqlite_exact concurrent-connection test flake on macOS CI. The leaked server thread was also the Windows exit-hang root cause: a slow/failed client.shutdown() POST left serve_forever running, and the interpreter blocked on the open listening socket at process exit. Tests now capture the httpd run_server creates (by subclassing daemon.ThreadingHTTPServer) and force httpd.shutdown() + server_close() from the test thread if the normal shutdown path leaves the thread alive, asserting the thread died so a leak becomes a visible failure instead of a silent exit hang. --- mempalace/daemon.py | 11 ++++- tests/test_daemon.py | 109 ++++++++++++++++++++++++++----------------- 2 files changed, 76 insertions(+), 44 deletions(-) diff --git a/mempalace/daemon.py b/mempalace/daemon.py index 3440bd0c0b..f40adbb5a8 100644 --- a/mempalace/daemon.py +++ b/mempalace/daemon.py @@ -775,6 +775,15 @@ def __init__(self, palace_path: str): self.token = read_token(self.palace_path) self.host = endpoint.get("host") or HOST self.port = int(port) + # The daemon is always on 127.0.0.1, so a request must never go through + # an HTTP proxy.

On Windows signal 0 is signal.CTRL_C_EVENT, so Python routes it to GenerateConsoleCtrlEvent and sends a console Ctrl-C to the target's process group rather than probing the pid. DaemonClient polls a same-process endpoint during startup, so on a CI runner with an attached console that Ctrl-C was delivered back to the interpreter as a spurious KeyboardInterrupt — the Windows CI hang that interrupted the suite at the first daemon HTTP-lifecycle test (socket.py recv). Probe via the Win32 OpenProcess/WaitForSingleObject handle API instead, which has no signalling side effects. This is also a real Windows production bug, not just a test artifact.

Add a SessionEnd hook that takes one final flush. Claude Code budgets SessionEnd hooks at 1.5s and a plugin-provided timeout cannot raise it, and a cold mempalace start exceeds that, so the wrapper backgrounds the work and returns immediately; the detached child completes the transcript ingest, project mine, and diary checkpoint after the session exits. The handler validates transcript_path through _validate_transcript_path before any ingest or diary write, so a traversal or wrong-suffix path is rejected while the independent project mine still runs. Adds hook_session_end, both shell wrappers, the plugin hooks.json entry, the session-end CLI choice, and focused tests.

Privacy: the queue DB's SQLite WAL/SHM sidecars hold un-checkpointed verbatim payloads but were created with the caller's umask. Set the owner-only umask in run_server BEFORE DaemonRuntime builds the QueueStore (not only once the HTTP server starts), and harden any existing sidecars in QueueStore._init_db as defense-in-depth. 2. DoS guard: reject a negative Content-Length in the request reader. rfile.read(-1) would block until the client disconnects and bypass the MAX_BODY_BYTES cap. 3. Side effects: extract _wal_log (+ _ensure_wal, _WAL_FILE, _WAL_REDACT_KEYS) into a new side-effect-free mempalace/wal.py. The CLI sync path and the daemon service layer obtained _wal_log via `from .mcp_server import _wal_log`, which runs mcp_server's import-time stdio protection (os.dup2(2, 1); sys.stdout = sys.stderr) in a non-MCP process and misroutes operator output. mcp_server/cli/service now import from mempalace.wal. 4. Correctness: run_mcp_tool treated any dict as success. Write tools that return a bare {"error": ...} (e.g. tool_create_tunnel/tool_delete_tunnel validation) were recorded as succeeded; now the "error" key infers failure. 5. Hook budget: get_client_if_running()/health() take an explicit timeout, and the hook "is the daemon up?" precheck uses a short HOOK_PROBE_TIMEOUT (0.5s) so a wedged daemon can't stall the hook for the default 5s. Adds tests/test_wal.py (import isolation + redaction) and daemon tests for the umask ordering, negative Content-Length, run_mcp_tool error inference, and the short probe timeout. --- mempalace/cli.py | 2 +- mempalace/daemon.py | 45 +++++++++++++---- mempalace/hooks_cli.py | 7 ++- mempalace/mcp_server.py | 83 +++--------------------------- mempalace/service.py | 9 +++- mempalace/wal.py | 97 +++++++++++++++++++++++++++++++++++ tests/test_daemon.py | 106 +++++++++++++++++++++++++++++++++++++++ tests/test_mcp_server.py | 12 ++--- tests/test_sync.py | 6 +-- tests/test_wal.py | 42 ++++++++++++++++ 10 files changed, 309 insertions(+), 100 deletions(-) create mode 100644 mempalace/wal.py create mode 100644 tests/test_wal.py diff --git a/mempalace/cli.py b/mempalace/cli.py index 5fe202584e..0773665e74 100644 --- a/mempalace/cli.py +++ b/mempalace/cli.py @@ -692,8 +692,8 @@ def cmd_sync(args): _submit_daemon_cli_job("sync", payload, args, background=getattr(args, "background", False)) return - from .mcp_server import _wal_log from .palace import MineAlreadyRunning + from .wal import _wal_log from .backends import detect_backend_for_path from .palace import _backend_artifact_label, resolve_backend_name from .sync import sync_palace diff --git a/mempalace/daemon.py b/mempalace/daemon.py index cccca616d9..3b9b45dca5 100644 --- a/mempalace/daemon.py +++ b/mempalace/daemon.py @@ -32,6 +32,11 @@ HOST = "127.0.0.1" STATE_ROOT_ENV = "MEMPALACE_DAEMON_STATE_ROOT" DEFAULT_WAIT_TIMEOUT = 60.0 * 60.0 +# Liveness-probe timeout for the hook "is a daemon already running?" precheck. +# Kept well under the ~500ms hook budget so a wedged daemon can't stall the hook +# (it falls back to the direct/spawn path instead).

On six-figure palaces these exceed the MCP host tool-call limit (180k drawers ~3-4 min; 349k times out at 120-240s). The 5s metadata cache only dedups repeat calls — it does not stop the cold-call timeout. A correct single-query SQL cross-tab already exists (`backends.chroma._sqlite_wing_room_counts`) and is already the CLI default (`miner.status`), but the MCP tools never used it — and the MCP-side sqlite reader only ran behind the `vector_disabled` recovery path. Add `_sqlite_taxonomy()` (guards on `_is_chroma_backend()`, returns None to fall back) and wire it as the default path into all four overview tools. They now answer from one GROUP BY without touching HNSW. Non-chroma backends (qdrant, sqlite_exact) and unbootstrapped/legacy layouts fall back to the existing client path unchanged. graph_stats (also named in #1379) builds an in-memory graph via build_graph() and needs its own treatment — tracked separately. --- mempalace/mcp_server.py | 67 ++++++++++++++++++++++++++++++++++++++++ tests/test_mcp_server.py | 29 +++++++++++++++++ 2 files changed, 96 insertions(+) diff --git a/mempalace/mcp_server.py b/mempalace/mcp_server.py index 68d8a1cd40..76b53d09a4 100644 --- a/mempalace/mcp_server.py +++ b/mempalace/mcp_server.py @@ -973,6 +973,29 @@ def _tool_status_via_sqlite() -> dict: return result +def _sqlite_taxonomy(): + """Fast wing→room tally straight from ``chroma.sqlite3`` (#1748 / #1379). + + Returns ``(total, {wing: {room: count}})`` or ``None`` to signal the + caller to fall back to the ChromaDB client pagination path. ``None`` means + a non-chroma backend, a missing/unbootstrapped palace, or a sqlite error — + exactly the cases ``backends.chroma._sqlite_wing_room_counts`` already + handles for the CLI ``miner.status()``.

On the pgvector write path a NUL in `document` is rejected by psycopg ("PostgreSQL text fields cannot contain NUL (0x00) bytes") and a NUL in `metadata` becomes a JSON unicode escape the jsonb cast rejects ("unsupported Unicode escape sequence"). `_execute` re-wraps either as BackendError and `_mine_impl` re-raises, so the whole mine exits non-zero and every file after the offending one is left unmined. ChromaDB, SQLite, and Qdrant store the byte verbatim, so only pgvector hard-fails. Add a recursive `_strip_nul` helper and apply it to id, document, and metadata in `_PgVectorClient.upsert_rows`, mirroring the backend-layer sanitization `_sanitize_documents_for_chromadb` already does for lone surrogates on the same bulk-ingest paths. ids are SHA-256 hashes and metadata keys are fixed field names, so the id and key passes are no-ops in practice; only transcript-derived values change.

FROM documents ORDER BY rowid, no LIMIT/OFFSET) and sliced in Python, so every paginating caller (prefetch_mined_set, status, exporter, migrate, dedup, sync, ...) re-scanned the entire table per page, making the sweep O(N^2) in rows materialized.

Matching is on the exact full stored value; results now expose source_path (the full path) for round tripping, since the displayed source_file is a basename. The MCP schema gains the source_file property and a path-tolerant sanitizer rejects null bytes, lone surrogates, and overlong values.

Hardening: - Pin the Host header to loopback literals + the bound host on a loopback bind (DNS-rebinding defense); relaxed for a deliberately non-loopback bind, which is the operator's call and may sit behind a Host-rewriting proxy. - Reject any browser Origin that isn't a loopback origin (rebinding/SSRF guard); non-browser MCP clients omit Origin and are unaffected. - Optional bearer token via MEMPALACE_MCP_HTTP_TOKEN (constant-time compare); required on /mcp, never on /healthz so liveness probes work credential-free. - Warn loudly when bound to a non-loopback host (palace reachable from network). Testability: - Split _build_http_server() out of _serve_http() so tests bind 127.0.0.1:0 and drive the real handler over a loopback socket via stdlib http.client. - Replace the skipped Starlette reimplementation with 12 tests covering dispatch, initialize, /healthz, 404, parse-error, the 16 MiB cap, notification 202, and the Host/Origin/token rejections — no third-party deps. --- mempalace/mcp_server.py | 143 +++++++-- tests/test_mcp_http_transport.py | 490 +++++++++++++------------------ 2 files changed, 324 insertions(+), 309 deletions(-) diff --git a/mempalace/mcp_server.py b/mempalace/mcp_server.py index f72900270c..8d1a3f32b5 100644 --- a/mempalace/mcp_server.py +++ b/mempalace/mcp_server.py @@ -48,6 +48,7 @@ import logging # noqa: E402 import re # noqa: E402 import hashlib # noqa: E402 +import hmac # noqa: E402 import sqlite3 # noqa: E402 import threading # noqa: E402 import time # noqa: E402 @@ -4562,30 +4563,72 @@ def _json_rpc_parse_error(req_id=None): } -# Module-level lock and limit used by the HTTP transport. -# Must be at module scope so _serve_http() and any future HTTP helpers -# can reference them without a closure or import. - - # Module-level constants for the HTTP transport. -# Defined here (not inside main()) so _serve_http() and _run_http_loop() +# Defined here (not inside main()) so _serve_http() / _build_http_server() # can reference them as free names without a NameError. _HTTP_REQUEST_LOCK = threading.Lock() _HTTP_MAX_REQUEST_BYTES = 16 * 1024 * 1024 +# Host literals that always denote this machine.

Add pytest-rerunfailures and wire `--reruns 2 --only-rerun "Failed to apply logs to the hnsw segment writer"` into the test-windows job only. The --only-rerun scope means a real, deterministic failure still fails on the first run; only this specific transient native-dependency error is retried. The Linux and macOS jobs deliberately keep zero reruns so genuine regressions surface there loudly. --- .github/workflows/ci.yml | 8 +++- pyproject.toml | 8 ++++ uv.lock | 95 ++++++++++++++++++++++++++++++---------- 3 files changed, 87 insertions(+), 24 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 671e1da543..80e3e5def5 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -30,7 +30,13 @@ jobs: python-version: "3.13" cache: 'pip' - run: pip install -e ".[dev]" - - run: python -m pytest tests/ -v --ignore=tests/benchmarks --cov=mempalace --cov-report=term-missing --cov-fail-under=80 --durations=10 + # ChromaDB's rust HNSW core intermittently fails compaction on Windows + # ("Failed to apply logs to the hnsw segment writer") regardless of our + # code — a long-standing, non-reproducible-on-Linux/macOS flake.

Opt-in and local-only — nothing binds to a public interface. (#1826) + +- **Opt-in HTTP transport for the MCP server.** `mempalace-mcp --transport http` serves JSON-RPC at `POST /mcp` (with a `GET /healthz` liveness probe) for operators running MemPalace behind a long-lived HTTP MCP client/proxy, avoiding the long-lived-stdio framing failures of #1801. stdio remains the default and is unchanged. The transport reuses the exact stdio request dispatcher (no separate write/search path), binds `127.0.0.1` by default, and is hardened against the two ways a local HTTP server leaks to the network: it pins the `Host` header to loopback on a loopback bind and rejects any non-loopback browser `Origin` (DNS-rebinding/SSRF guard), and supports an optional bearer token via `MEMPALACE_MCP_HTTP_TOKEN` (required on `/mcp`, never on `/healthz`). A 16 MiB request cap and a loud warning when bound to a non-loopback host round it out. (#1801, #1806) + +- **`mempalace_checkpoint` batch-save MCP tool.** Collapses multiple `add_drawer` calls plus an optional diary entry into a single MCP round-trip for agents that want to file a whole session at once. Stores content verbatim and reuses the existing idempotent add/dedup path. (#1851) + +- **`mempalace_delete_by_source` bulk-cleanup MCP tool.** Exact-match, dry-run-by-default deletion of every drawer (and its matching closet/AAAK index entries) for a given `source_file` — the recourse for benchmark/eval files mined into the same wing as real data and drowning out search. The dry run reports the drawer and closet blast radius before anything is removed, and the commit writes a WAL audit entry. (#1722, #1729) + +- **Optional `source_file` filter for `mempalace_search`.** Scope a search to an exact stored source path. The filter is threaded through every search path (vector, BM25/SQLite fallback, lexical union, and index-mismatch fallback) so it never silently drops a matching drawer, and results now expose the full `source_path` as a round-trippable key. (#1815, #1817) + +- **New transcript parsers / importers.** Continue.dev session parser (#731), Gemini CLI / AI Studio JSON session import (#204), and a Pi agent JSONL session normalizer (#169). + +- **Wider miner language coverage.** C# / .NET, PHP (#1819), Swift / Kotlin (#1368), and Java project detection including rootless subprojects (#1720). + +- **Final mine on Claude plugin `SessionEnd`.** The Claude Code plugin now runs a closing mine when a session ends so the last exchanges are captured without waiting for the next save nudge. (#1814, #1820) + +### Performance + +- **Overview/status MCP tools answer from the SQLite aggregate.** Large palaces no longer time out building wing/room/status overviews — the counts come from a single SQLite aggregate instead of a client-side fetch-and-tally. (#1748, #1379) + +- **`graph_stats` SQLite fast path.** Knowledge-graph stats are computed in SQLite rather than walking the collection, fixing large-palace timeouts. (#1379) + +- **Embedder caps ONNX-runtime intra-op threads** so a background mine no longer pins every core. (#1068) + +- **Backend pagination pushed into the query.** `sqlite_exact` (#1841, #1842) and `pgvector` (#1830, #1840) now apply `get(limit, offset)` in SQL, and Qdrant fetches bulk metadata in a single scroll with a larger page size (#1796, #1832). + +### Bug Fixes + +- **pgvector tolerates hostile transcript bytes.** A lone Unicode surrogate (#1833) or a NUL byte (#1829) in a transcript no longer aborts the whole mine — both are sanitized before the row is written. + +- **SQLite read-only URIs are percent-encoded** so palace paths with spaces or special characters open correctly, and `_sqlite_graph_stats` is routed through the same `sqlite_read_uri` helper. + +- **Stale ChromaDB HNSW divergence routes to the SQLite fallback** instead of failing the read outright. (#1816, #1822) + +- **Diverged-index recovery now points at `repair --mode from-sqlite`, not a re-mine.** A failed ChromaDB HNSW compaction leaves the index out of sync while the rows stay intact in `chroma.sqlite3`; the old "re-mine from source" advice silently dropped MCP-added drawers and diary entries (which have no source file). Both the legacy `repair`/`rebuild_index` error messages and the `repair-status` recommendation, plus the recall skill docs, now guide users to rebuild from SQLite. (#1843, #1847, #1849) + +- **The MCP server refuses a second writer for the same palace** rather than letting two processes race the same HNSW handle. (#1818, #1823) + +- **Windows hook miner spawns with `CREATE_NO_WINDOW`** so background mines no longer flash a console window. (#1783, #1848) + +- **`fact_checker` `__main__` no longer emits a runpy warning** under the test runner.

Swap it to CREATE_NO_WINDOW, matching the hook miner's _detached_popen_kwargs fixed in #1848 — the dedicated follow-up the review bot asked for. `grep -rn DETACHED_PROCESS mempalace/` now returns zero production hits. Survivability is unchanged: CREATE_BREAKAWAY_FROM_JOB (escapes the parent Job Object's kill-on-close) plus the daemon never being attached to the launching console carry survive-terminal-close; CREATE_NEW_PROCESS_GROUP (also kept) isolates Ctrl-C/Break. CREATE_NO_WINDOW is ignored when OR'd with DETACHED_PROCESS, so this replaces the flag rather than adding it. The daemon already redirects stdout/stderr to daemon.log and reads no stdin, so it needs no console.

Add _safe_wing_slug(): collapse non-word runs to '_', trim, and fall back to 'sessions' when a name reduces to nothing. Route the three wing-derivation sites through it. Tests: unit cases for the helper plus a hypothesis property test asserting wing_ always passes sanitize_name for any input. * fix: preserve dots and apostrophes in wing slug for backward compatibility The first pass collapsed every non-word character (including dot and apostrophe) to underscore, renaming existing valid wings — e.g. my.app became wing_my_app — which would orphan diary entries already filed under the old name. Keep dot and apostrophe (both accepted by sanitize_name), collapse consecutive dots to avoid the path-traversal rejection, and trim edge separators. Add backward-compatibility tests for previously-valid names plus a double-dot collapse test. * fix: cap wing slug length to stay within sanitize_name's limit sanitize_name rejects names over 128 characters, so a very long project directory name would produce a wing name that fails validation, re-triggering the silent auto-save break this PR fixes. Truncate the slug to 120 chars (the wing_ prefix keeps the total under 128). Widen the hypothesis property test to max_size=300 so it exercises the length path, and add an explicit truncation test.

If config.json\nstores palace_path as '~/.mempalace/palace' (the default written by\ninit), the tilde was returned unexpanded.\n\nDownstream callers such as cli.py cmd_mine did call expanduser when\n--palace was passed explicitly, but fell through to MempalaceConfig()\nwhen no flag was given, inheriting the unexpanded string. Python's\nos.makedirs and chromadb.PersistentClient treat a leading tilde as a\nliteral directory name rather than the home directory, so the palace\nwas silently written to a CWD-relative path such as\nmy_project/~/.mempalace/palace.\n\nThe fix is a single os.path.expanduser() call on line 343 of\nconfig.py, mirroring the existing env-var branch on line 342. Since\nDEFAULT_PALACE_PATH is already expanded at module load (line 197),\nexpanduser on an absolute path is a no-op, so the default case is\nunaffected.\n\nSymptoms: scattered {project}/~/.mempalace/palace directories, palace\nalways appears empty after mine, search returns Collection does not\nexist, launchd-driven nightly mine writes to a different location than\ninteractive mine.\n\nCo-Authored-By: Claude Sonnet 4.6 n (#1865) --- mempalace/config.py | 2 +- tests/test_config_palace_path.py | 33 ++++++++++++++++++++++++++++++++ 2 files changed, 34 insertions(+), 1 deletion(-) create mode 100644 tests/test_config_palace_path.py diff --git a/mempalace/config.py b/mempalace/config.py index 36a1703b3b..33ec057262 100644 --- a/mempalace/config.py +++ b/mempalace/config.py @@ -340,7 +340,7 @@ def palace_path(self): # code path (mcp_server.py:62) and prevent surprise redirection # when the env var contains unresolved components. return os.path.abspath(os.path.expanduser(env_val)) - return self._file_config.get("palace_path", DEFAULT_PALACE_PATH) + return os.path.expanduser(self._file_config.get("palace_path", DEFAULT_PALACE_PATH)) @property def tunnel_file(self): diff --git a/tests/test_config_palace_path.py b/tests/test_config_palace_path.py new file mode 100644 index 0000000000..9797be471f --- /dev/null +++ b/tests/test_config_palace_path.py @@ -0,0 +1,33 @@ +"""Tests for palace_path tilde expansion in MempalaceConfig.""" + +import os +from mempalace.config import MempalaceConfig + + +def test_palace_path_expands_tilde_from_config_file(): + """palace_path must expand ~ even when read from config.json, not env.""" + cfg = MempalaceConfig() + cfg._file_config["palace_path"] = "~/.mempalace/palace" + result = cfg.palace_path + assert not result.startswith("~"), ( + f"palace_path returned unexpanded tilde: {result!r}.

A small/low-fanout index where every element stays on layer 0 serializes an empty link_lists.bin and loads fine. Flagging that shape as corrupt produced a self-perpetuating quarantine loop — repair rebuilt the byte-identical all-layer-0 segment, the next cold start re-quarantined it, accumulating drift dirs (221 MB in the reported case) with no ingestion involved. Use the persist-completion marker as the discriminator instead. ChromaDB writes index_metadata.pickle last, so an intact pickle envelope proves the flush finished and the empty link_lists.bin is the legitimate all-layer-0 shape. Only treat an empty link_lists.bin as a partial flush when there is real payload AND no completion marker (absent or truncated pickle). The #1457 partial-flush protection (real payload, no/truncated marker) is preserved; the byte-sniff is factored into _hnsw_metadata_marker_intact and reused by _segment_appears_healthy. Also fixes the related single-writer stale-quarantine false positive (#1564), which shares this all-layer-0 root cause. --- mempalace/backends/chroma.py | 71 +++++++++++++++++++++++-------- tests/test_hnsw_payload_health.py | 40 ++++++++++++----- 2 files changed, 83 insertions(+), 28 deletions(-) diff --git a/mempalace/backends/chroma.py b/mempalace/backends/chroma.py index fc9d90a46a..4b832335a3 100644 --- a/mempalace/backends/chroma.py +++ b/mempalace/backends/chroma.py @@ -82,13 +82,52 @@ def _hnsw_link_to_data_ratio(seg_dir: str) -> Optional[float]: return link_size / data_size -def _hnsw_link_lists_is_usable_for_payload(seg_dir: str) -> bool: - """Return False when a non-trivial HNSW payload lacks usable link lists. +def _hnsw_metadata_marker_intact(seg_dir: str) -> bool: + """Return True when ``index_metadata.pickle`` bears a complete envelope. + + ChromaDB writes ``index_metadata.pickle`` last during a persist, so an + intact pickle envelope — protocol marker ``0x80`` at the head, ``STOP`` + byte ``0x2e`` at the tail — proves the flush finished.

An app that configured logging before importing mempalace.mcp_server lost its setup: a host on DEBUG dropped to INFO, custom formatters and handlers were replaced. force=True existed (#1495) only to keep MEMPALACE_LOG_FILE working when root already had handlers. This keeps that contract without the reset: configure root only when it is unconfigured (standalone); otherwise attach a mempalace-filtered file handler additively and leave the host's config alone. Adds _MempalaceLogFilter so the file captures every mempalace logger (the dotted mempalace.* family plus the flat mempalace_* names) and nothing else. * fix(mcp): survive importlib.reload and pin file log format (#1860) Addresses review on #1885. Restore _logging_configured from globals() so the idempotency guard survives importlib.reload: a reload re-executes the module body, and a plain reset would let _init_logging() stack a duplicate file handler on root. Set an explicit "%(message)s" formatter on the file handler so the embedded path does not depend on logging's default formatter (which already renders the same, but is now pinned and identical to the standalone path). Adds a reload regression test and a format-pin assertion. --- mempalace/mcp_server.py | 140 +++++++++++++++++++++++++++----------- tests/test_mcp_server.py | 142 ++++++++++++++++++++++++++++++++++++++- 2 files changed, 242 insertions(+), 40 deletions(-) diff --git a/mempalace/mcp_server.py b/mempalace/mcp_server.py index 9ef35a4e89..c0aabfa2b6 100644 --- a/mempalace/mcp_server.py +++ b/mempalace/mcp_server.py @@ -101,63 +101,127 @@ from .ids import ID_RECIPE, make_drawer_id_from_content # noqa: E402 -def _init_logging() -> None: - """Root-logger init: always stderr, optionally append to ``MEMPALACE_LOG_FILE``. +class _MempalaceLogFilter(logging.Filter): + """Pass only records emitted by mempalace's own loggers. + + Lets the ``MEMPALACE_LOG_FILE`` handler attach to an already-configured + root logger (a host app embedding the server, #1860) without copying the + host's — or a third-party library's — records into mempalace's diagnostic + file. mempalace loggers are ``mempalace`` / ``mempalace.*`` (the dotted + ``__name__`` family) plus the flat ``mempalace_mcp`` / + ``mempalace_format_miner`` / ``mempalace_hallways`` / ``mempalace_graph`` + loggers — every one is prefixed ``mempalace``. + """ + + def filter(self, record: logging.LogRecord) -> bool: + name = record.name + return name == "mempalace" or name.startswith(("mempalace.", "mempalace_")) + + +# Preserved across importlib.reload via globals(): a reload re-executes this +# module body, so a plain ``= False`` would reset the guard and let +# _init_logging() stack a duplicate file handler. globals().get keeps the prior +# True so the guard survives reload (#1885 review). +_logging_configured = globals().get("_logging_configured", False) + - Stderr-only is the default.

ChromaBackend.detect() was returning True for a 0-byte chroma.sqlite3 file because the check was just os.path.isfile(...). On a palace that has any other backend marker alongside a stale 0-byte chroma.sqlite3, resolve_backend_name then raises BackendMismatchError and the palace becomes unopenable until the user manually rm's the empty file. The 0-byte file appears as a side effect of any sqlite3.connect() on a missing path — Python creates the file immediately but writes the SQLite header only on the first statement. So any code path that touches the chroma.sqlite3 path with bare sqlite3.connect(), including chromadb's own PersistentClient lazy-init (see the comment at backends/chroma.py:2052), can leave a 0-byte artifact behind. Fix: detect() now reads the first 16 bytes and compares to the SQLite magic prefix b"SQLite format 3\x00" instead of relying on file presence alone. One extra open() + 16-byte read; detect() isn't a hot path. Properties: - Rejects 0-byte files (the symptom #1893 is about). - Rejects non-SQLite garbage at the canonical path (partial writes, etc.). - Doesn't false-negative on real chroma palaces: any chroma palace whose PersistentClient has done any work has the magic header on disk (verified — CREATE TABLE is enough to land the header). - Doesn't couple detect() to chroma's specific schema; the magic header is stable across chromadb releases. Test sweep: many test files used (chroma.sqlite3).touch() or .write_bytes(b"") as a "fake palace" shortcut, exploiting the loose isfile() check (one such site even had the comment "# pass the isfile guard"). After this change, those stand-ins no longer register as chroma palaces. Introduced tests/_chroma_palace_helper.py::make_minimal_chroma_sqlite following the existing _backend_conformance.py precedent, and updated 15 call sites across 8 test files to use it. The existing test_chroma_detect_matches_palace_with_chroma_sqlite (which encoded the buggy semantics with write_bytes(b"")) is renamed to test_chroma_detect_matches_palace_with_sqlite_header and now writes a real SQLite database via the helper. Added two new tests for the rejection paths (empty file, non-SQLite garbage). Full env-cleared suite: 3137 passed, 20 skipped, 0 failed. ruff check and ruff format --check both clean. Co-Authored-By: Claude Opus 4.7 Claude-Session: https://claude.ai/code/session_01KC5Qsknh2zFRtRvVyjXiTA * fix(sqlite_exact): require SQLite magic header for SQLiteExactBackend.detect() Per gemini-code-assist review on #1892 PR #1896: SQLiteExactBackend has the same os.path.isfile() detection pattern as ChromaBackend did, with the same 0-byte-file vulnerability. Mirrors the chroma fix for repo-wide consistency. - SQLiteExactBackend.detect() now does the same 16-byte SQLite magic-prefix check as ChromaBackend.detect(). - _chroma_palace_helper.py: factored its body into a private _write_minimal_sqlite_file() and gained a sibling make_minimal_sqlite_exact_sqlite() for the sqlite_exact filename. No churn to any existing chroma call sites. - test_sqlite_exact_backend.py:426 (the one site that wrote b"" for sqlite_exact.sqlite3) updated to use the new helper. - Three new tests in test_sqlite_exact_backend.py mirror the chroma trio: matches with valid header, rejects empty file, rejects non-SQLite garbage. Full env-cleared suite: 3140 passed, 20 skipped, 0 failed.

For remote pgvector deployments (TLS over WAN), `mempalace_status` and every other metadata-only consumer was transferring the full `document` column over the wire even when nothing read it. A single scroll over a 177K-drawer palace on a 175 ms-RTT link moved ~150 MB of document text plus ~50 MB of metadata; this PR drops that to ~50 MB. scroll_rows / _scroll gain `with_document: bool = True`. When False, SELECT projects NULL::text instead of the document column. Positional _row parser unchanged (record[1] stays the document slot, just receives NULL). Existing callers default to True and see byte-for-byte identical behavior. PgVectorCollection.get_all_metadata override: where=None path goes single-scroll with with_document=False. Filtered path falls back to base to keep _matches_where running on array/object metadata values (same correctness contract as #1840's filtered-path decision). Tests: - Update _FakePgVectorClient.scroll_rows to accept with_document; mirror the NULL-becomes-empty-string semantics when False - Update 5 existing scroll_calls assertions to include with_document=True (unchanged intent) - test_pgvector_get_all_metadata_skips_document_column: assert exactly one scroll call with with_document=False - test_pgvector_get_all_metadata_filtered_falls_back_to_base: assert filtered path preserves with_document=True Co-Authored-By: Claude Opus 4.7 Claude-Session: https://claude.ai/code/session_01KC5Qsknh2zFRtRvVyjXiTA * fix(pgvector): extend with_document=False fast path to filtered get_all_metadata Per gemini-code-assist review feedback on #1892: _matches_where only reads metadata, so the where=None vs where=set conditional fall-back was unnecessary. The filtered path can use the same single-scroll with_document=False fast path and apply the post-filter locally on metadata dicts — extending the wire-byte win to every get_all_metadata caller, not just unfiltered ones. Mirrors the pushdown + local _matches_where pattern already used by _rows in the same file: pushdown when _requires_local_filter is False, post-filter in Python otherwise. Same correctness contract as #1840's filtered get path. Renames test_pgvector_get_all_metadata_filtered_falls_back_to_base to test_pgvector_get_all_metadata_filtered_uses_fast_path and asserts the new behavior (with_document=False + pushdown forwards the equality filter to SQL).

The recency-window fallback and any date-aware consumer then saw ingest order, not when content was written. - convo_miner: derive `authored_at` (per-file max line `timestamp`) and store it as drawer metadata; falls back to `filed_at` when absent - searcher: surface `authored_at` in search results, and break exact hybrid-score ties toward the more recently authored drawer (ISO strings sort chronologically; missing dates sort oldest) — benchmark-neutral as it only reorders exact ties - tests: cover `_extract_authored_at` (latest wins, skips/tolerates lines without timestamps, non-jsonl/missing -> None) and the tie-break Co-Authored-By: Claude Opus 4.8 * feat(search): surface authored_at in CLI + backfill for existing data Completes the authored_at work so the field is visible end-to-end and existing palaces can adopt it without re-mining. - layers: CLI `search` output shows an `authored:` date line per result (peer of the existing date; markdown drawers fall back to filed_at) - scripts/backfill_authored_at.py: in-place migration that stamps authored_at on convos drawers from their source transcripts — metadata only (no re-embedding), idempotent, dry-run by default - docs/authored-at.md: documents created_at (ingest) vs authored_at (written) and both backfill paths (in-place / drop-and-recreate) - tests: backfill integration tests over an ephemeral ChromaDB collection Co-Authored-By: Claude Opus 4.8 * fix(search): address review — non-string timestamp guard + top-level authored_at tiebreak Two correctness fixes from the PR review: - _extract_authored_at: only compare when the parsed `timestamp` is a str. A non-string timestamp on a malformed/foreign JSONL line previously raised TypeError outside the try and could crash the mine. - _hybrid_rank: the tie-break read `authored_at` only from nested `metadata`, but the search_memories path (MCP / Claude Code) carries it at the top level of each hit — so the tie-break silently no-op'd there. Read both shapes. - tests: non-string timestamp cases, and a top-level-shape tie-break test (which fails before this fix).

The lock re-entrancy guard was thread-local, so write handlers (add_drawer/update_drawer) failed to see the process-held lease, re-acquired the flock, and self-conflicted with "palace ... is held by PID ". Reads worked (no lock); writes over the HTTP transport were impossible. Make the re-entrancy record process-wide (pid-tagged, guarded by a threading.Lock) so a write from any thread of the process that already holds the lease passes through. Safe: flock is per-process and HTTP writes are serialized by _HTTP_REQUEST_LOCK. Preserves fork-safety, same-thread nesting (miner.mine -> ChromaCollection.upsert), and cross-process protection (MineAlreadyRunning still raised between processes). Add cross-thread same-process regression test. Co-Authored-By: Claude Opus 4.8 * fix(palace): reset lock guard on fork to avoid inherited-locked deadlock Address review (PR #1859): `_palace_lock_guard` is a threading.Lock, so a child forked while another thread held it would inherit it locked (the holder thread is gone in the child) and deadlock on the next acquire. Register an os.register_at_fork(after_in_child=...) handler that replaces the guard with a fresh unlocked lock and clears state; the child must reacquire the flock anyway. Guarded by hasattr(os, "register_at_fork") for Windows.

This adds optional since/before ISO date bounds on filed_at: since is inclusive, before is exclusive. The filter runs in Python after the rows are fetched. ChromaDB 1.5.7 rejects string operands for $gte/$lt and filed_at is stored as an ISO string, so a server-side where comparison is not available; the tool already collapses and paginates the full result set in Python. Drawers whose filed_at is missing or unparseable are excluded while a bound is active, and inverted bounds (since >= before) return a clear error. * test: close chromadb clients between tests to fix Windows handle leak (#1128) chromadb 1.5.7 caches one System per palace path and only frees the SQLite/HNSW file handles on client.close(); the collection fixture and the per-test MCP cache reset only dereferenced the client, so handles leaked across the session. Harmless on POSIX (rmtree unlinks open files), but on Windows the handles stay locked and accumulate until an HNSW segment write in a later test's setup fails, which surfaced here as TestDeleteBySource::test_commit_purges_matching_closets asserting 0 == 2. Close the client in the collection fixture and in _reset_mcp_cache so the handles are released between tests. * test: release backend chromadb clients between tests (#1128) palace.get_collection() caches one PersistentClient per palace_path on the process-wide backend singleton and never closes it; sweep, repair and several CLI tests reach the store through it. chromadb frees the rust-side SQLite/HNSW file handles only on client.close(), so the handles leak across the whole session: a 30-palace probe shows ~200 open file descriptors into the palace tree, dropping to 0 once the clients are closed. On POSIX the open handles are harmless (rmtree unlinks open files), but on Windows they stay locked and accumulate until a later test's HNSW segment write fails ("Failed to apply logs to the hnsw segment writer"), e.g. test_sweeper.py::TestSweeperTandem::test_sweep_recovers_untaken_message_at_cursor_timestamp. Drain the cached clients in the autouse _reset_mcp_cache teardown via close_palace(), which closes each PersistentClient (releasing its handles) without marking the backend closed so it stays reusable. Complements the collection-fixture and _client_cache close() added earlier. --- mempalace/mcp_server.py | 114 +++++++++++++++++- tests/conftest.py | 40 ++++++- tests/test_mcp_server.py | 251 +++++++++++++++++++++++++++++++++++++++ 3 files changed, 401 insertions(+), 4 deletions(-) diff --git a/mempalace/mcp_server.py b/mempalace/mcp_server.py index c0aabfa2b6..64c71393ce 100644 --- a/mempalace/mcp_server.py +++ b/mempalace/mcp_server.py @@ -1270,6 +1270,77 @@ def _sanitize_optional_source_file(value: str = None) -> str: return value +def _parse_date_filter(value: Optional[str] = None, field_name: str = "date") -> Optional[datetime]: + """Parse an optional ISO-8601 date/datetime filter bound (#1128). + + Accepts a date (``"2026-04-01"``), a naive timestamp + (``"2026-04-01T09:30:00"``), or one carrying a ``Z``/``+HH:MM`` offset. + Returns a naive ``datetime`` for wall-clock + comparison against drawer ``filed_at`` values, which are stored as naive + local ISO strings (``datetime.now().isoformat()``).

(matches get()/lexical_search() ordering). - test_tool_get_taxonomy_uses_metadata_facets compared concurrent room facet calls via set(), but a call() with a dict kwarg is unhashable; compare order-independently via membership instead. --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> Co-authored-by: Igor Lins e Silva

Add a no-LLM structural entity extractor and wire it into the convos mine: - entities: structural-only extractor (author-quoted code spans, URLs, file paths, qualified identifiers, CamelCase / snake_case symbols). No wordlists, no NLP models, precision-biased so prose doesn't pollute the graph. - convo_miner: set `entities` per chunk, and compute hallways after a convos mine (mirroring the project-file path). Hallways run before the FTS5 validation, which opens a direct sqlite connection that can invalidate the live Chroma collection handle on some Chroma builds. - cli: `mempalace hallways` lists the associative graph (CLI parity with the list_hallways MCP tool). - tests: extractor precision/ranking, entities metadata at mine time, CLI. Co-Authored-By: Claude Opus 4.8 * fix(graph): address review — semicolon safety, leading-underscore snake, negative limit - entities `_clean`: strip `;` out of tokens so a URL query string or backtick span can't split the `;`-joined entities metadata field - entities `_SNAKE`: optional leading/trailing `_?` so `_extract_authored_at` and similar are matched in plain text (previously only caught via backticks) - cli `hallways`: clamp `--limit` with max(0, ...) so a negative value shows nothing instead of slicing from the end - tests for all three Co-Authored-By: Claude Opus 4.8 --------- Co-authored-by: Claude Opus 4.8 Co-authored-by: Igor Lins e Silva <4753812+igorls@users.noreply.github.com> --- mempalace/cli.py | 19 +++++++++ mempalace/convo_miner.py | 22 +++++++++++ mempalace/entities.py | 71 ++++++++++++++++++++++++++++++++++ tests/test_cli_hallways.py | 59 ++++++++++++++++++++++++++++ tests/test_convo_miner_unit.py | 36 +++++++++++++++++ tests/test_entities.py | 69 +++++++++++++++++++++++++++++++++ 6 files changed, 276 insertions(+) create mode 100644 mempalace/entities.py create mode 100644 tests/test_cli_hallways.py create mode 100644 tests/test_entities.py diff --git a/mempalace/cli.py b/mempalace/cli.py index c3b30258c0..1b2cea5d7d 100644 --- a/mempalace/cli.py +++ b/mempalace/cli.py @@ -1001,6 +1001,21 @@ def cmd_migrate_wings(args): ) +def cmd_hallways(args): + """List within-wing entity hallways (the auto-built associative graph).""" + from .hallways import list_hallways + + rows = list_hallways(getattr(args, "wing", None)) + if not rows: + print("No hallways yet — they are built from drawer entities when you mine.") + return + rows.sort(key=lambda h: h.get("co_occurrence_count", 0), reverse=True) + print(f" {len(rows)} hallway(s):") + for h in rows[: max(0, args.limit)]: + label = h.get("label") or f"{h.get('entity_a', '?')} <-> {h.get('entity_b', '?')}" + print(f" {label}") + + def cmd_status(args): from .miner import status @@ -1977,6 +1992,9 @@ def main(): ) p_migrate_wings.add_argument("--yes", action="store_true", help="Skip the confirmation prompt") + p_hallways = sub.add_parser("hallways", help="List entity hallways (associative graph)") + p_hallways.add_argument("--wing", default=None, help="Filter to one wing") + p_hallways.add_argument("--limit", type=int, default=50, help="Max hallways to show") p_status = sub.add_parser("status", help="Show what's been filed") p_status.add_argument( "--backend", @@ -2061,6 +2079,7 @@ def main(): "repair-status": cmd_repair_status, "migrate": cmd_migrate, "migrate-wings": cmd_migrate_wings, + "hallways": cmd_hallways, "status": cmd_status, } dispatch[args.command](args) diff --git a/mempalace/convo_miner.py b/mempalace/convo_miner.py index 2da32db081..e85a1ee6c6 100644 --- a/mempalace/convo_miner.py +++ b/mempalace/convo_miner.py @@ -21,6 +21,7 @@ from .collision_scan import assert_no_collisions from .ids import ID_RECIPE, make_convo_drawer_id, make_convo_sentinel_id from .normalize import normalize +from .entities import entities_metadata from .palace import ( NORMALIZE_VERSION, SKIP_DIRS, @@ -499,6 +500,7 @@ def _file_chunks_locked( "chunk_index": chunk["chunk_index"], "added_by": agent, "filed_at": filed_at, + "entities": entities_metadata(chunk["content"]), "authored_at": authored_at if authored_at is not None else filed_at, "ingest_mode": "convos", "extract_mode": extract_mode, @@ -628,6 +630,22 @@ def mine_convos( ) +def _compute_hallways_for_wing_safe(wing, collection, drawers_filed): + """Auto-populate the associative graph from the entities just mined. + + Best-effort: hallway computation must never fail an otherwise-good mine, and is + skipped when nothing new was filed. + """ + if drawers_filed <= 0: + return + try: + from .hallways import compute_hallways_for_wing + + compute_hallways_for_wing(wing, col=collection) + except Exception as exc: + print(f" (hallways skipped: {exc})") + + def _mine_convos_impl( convo_dir: str, palace_path: str, @@ -785,6 +803,10 @@ def _mine_convos_impl( break if not dry_run: + # Compute hallways before the FTS5 validation: the latter opens a direct sqlite + # connection to the Chroma DB, which can invalidate the live collection handle on + # some Chroma builds and make the hallway fetch fail. + _compute_hallways_for_wing_safe(wing, collection, total_drawers) _validate_palace_fts5_after_mine(palace_path) print(f"\n{'=' * 55}") diff --git a/mempalace/entities.py b/mempalace/entities.py new file mode 100644 index 0000000000..d2e5975e06 --- /dev/null +++ b/mempalace/entities.py @@ -0,0 +1,71 @@ +"""No-LLM structural entity extraction for the associative graph. + +Pulls deterministic, *structural* tokens from text — author-quoted code spans, URLs, +file paths, qualified identifiers, and CamelCase symbols — to populate the ``entities`` +drawer-metadata field that hallways/tunnels consume.

Server capabilities (mempalace/mcp_server.py): - Native TLS via --tls-cert/--tls-key (env MEMPALACE_MCP_TLS_CERT/_KEY): wraps the socket in a TLS 1.2+ context, validated before bind. Token is still required on a non-loopback bind (TLS != auth). - Read-only mode via --read-only (env MEMPALACE_MCP_READ_ONLY): the 24 mutating tools are hidden from tools/list and refused at dispatch (-32003), enforced before arg handling — not merely hidden. Turnkey command (mempalace/cli.py): - Auto-generates a strong bearer token for non-loopback binds, stored 0600 under ~/.mempalace/server/ and printed once; reused across restarts. Token rides in the child env, never argv, so it can't leak via ps. - Prints a ready-to-paste client config (scheme reflects TLS), then foreground-execs the real server so Docker/systemd own the lifecycle. Deployment (deploy/): - docker-compose.server.yml wires the server + Qdrant with a /healthz healthcheck and persistent volumes. - server.env.example documents the env surface. - mempalace-server.service is a hardened systemd unit template. Tests: TLS handshake (openssl-gated), read-only enforcement, token autogen/0600/reuse, token-not-in-argv, secure-by-default gates. Docs: remote-server guide now leads with `mempalace serve` plus Compose and systemd subsections. * test(serve): fix Windows — don't patch os.name; gate 0600 asserts to POSIX Patching os.name to 'posix' broke Path.home() on Windows (pathlib mixed POSIX home resolution with Windows drive parsing). Capture both exec branches (os.execve + subprocess.run) instead, and guard the POSIX permission-bit assertions behind os.name == 'posix' (Windows files report 0o666). --- deploy/docker-compose.server.yml | 71 ++++++++++++ deploy/mempalace-server.service | 48 ++++++++ deploy/server.env.example | 28 +++++ mempalace/cli.py | 181 +++++++++++++++++++++++++++++++ mempalace/mcp_server.py | 104 +++++++++++++++++- tests/test_mcp_http_transport.py | 117 ++++++++++++++++++++ tests/test_serve.py | 160 +++++++++++++++++++++++++++ website/guide/remote-server.md | 74 +++++++++---- 8 files changed, 762 insertions(+), 21 deletions(-) create mode 100644 deploy/docker-compose.server.yml create mode 100644 deploy/mempalace-server.service create mode 100644 deploy/server.env.example create mode 100644 tests/test_serve.py diff --git a/deploy/docker-compose.server.yml b/deploy/docker-compose.server.yml new file mode 100644 index 0000000000..e1e14e80e5 --- /dev/null +++ b/deploy/docker-compose.server.yml @@ -0,0 +1,71 @@ +# MemPalace remote team server — MCP over HTTP, backed by a central Qdrant. +# +# One command stands up a shared memory service a whole team's AI clients +# connect to.

Adds the two extensions to the two extension lists most relevant to them, each with a matching test. - ``mempalace/miner.py:READABLE_EXTENSIONS`` — ``.tex`` / ``.bib`` join the mining allowlist (parallel to the Swift/Kotlin PR #1368 and the PHP ecosystem PR #1819). - ``mempalace/entity_detector.py:PROSE_EXTENSIONS`` — ``.tex`` / ``.bib`` also join the *preferred* entity-detection bucket alongside ``.md`` / ``.rst`` / ``.csv``, NOT the broader code-file fallback. The reason ``PROSE_EXTENSIONS`` exists separately is documented in-code: programming-language files have lots of capitalized identifiers (class names, function names) that produce false-positive person matches. LaTeX/BibTeX don't have that problem — they're typesetting languages for prose documents. ``.bib`` in particular is almost entirely author names, one of the highest real-entity densities of any file type the detector scans. Tests follow the patterns established by the prior extension PRs: ``tests/test_miner.py::test_scan_project_includes_latex_files`` mirrors the Swift/Kotlin scan tests, and ``tests/test_entity_detector.py::test_scan_for_detection_includes_latex_prose`` mirrors ``test_scan_for_detection_finds_prose``. The existing ``test_prose_extensions`` was extended to assert the two new entries. Full env-cleared suite: 3216 passed, 20 skipped. ``ruff check .`` and ``ruff format --check .`` both clean.
