fix(vector): guard _group_int_doc_ids against non-int doc_id values
Skip and warn instead of stringifying floats / unexpected types in the backfill helper. A stray doc_id=3.0 would otherwise be rewritten to "3.0", which producers (str(int)) and the keyword index would never match, and which int() on the verification side would reject. Also add a doc_id=0 case to the backfill test to guard against a future falsy-skip regression. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

fix(vector): address PR review round 8 — anyio convention + cosine-safe sentinel + dedup get_collection
Reviewer findings (1 blocking + 2 important): - 🔴 Replace `import asyncio` / `await asyncio.sleep(0)` with `import anyio` / `await anyio.sleep(0)` in the four async side-effect helpers (_scroll_raises, _upsert_raises, _get_collection_raises, _create_index). CLAUDE.md mandates anyio for all async operations; conftest pins the backend to asyncio so the asyncio.sleep call worked today, but the inconsistency would surface the moment that pin moves. - 🟡 Replace the sentinel's zero dense vector with a single non-zero element (`[1e-9] + [0.0] * (dimension - 1)`). Cosine distance is mathematically undefined for the zero vector and Qdrant Cloud strict mode rejects zero-vector upserts. The exact value doesn't matter (sentinel never participates in a search — no user_id/doc_id/doc_type payload) but the upsert itself must be valid. - 🟡 Avoid the duplicate `get_collection` round-trip on every restart. `_ensure_payload_indexes` now accepts an optional `existing_schema: dict | None` parameter; when None it fetches collection_info itself (and the get_collection-failure swallow still applies), but `get_qdrant_client` already fetches collection_info for dimension validation in the existing-collection branch — pass `collection_info.payload_schema or {}` through to skip the second call. The new-collection branch passes `existing_schema={}` explicitly since a freshly created collection has no payload schema. The 🟡 deck_card iteration-fallback finding doesn't apply: the `isdigit()` guard at context.py:612 returns early before either the fast-path or the iteration fallback runs, so non-numeric doc_ids cannot reach the inner `c.id == int(doc_id)` comparison.

fix(vector): add BOOL index for is_placeholder + correct wait=True docstring
Reviewer feedback (2 items):
- Add a BOOL payload index for `is_placeholder` alongside the three
KEYWORD fields. Strict-mode index-required filtering on Qdrant Cloud
enforces a payload index on any field used in a `FieldCondition`
regardless of value type, so `get_placeholder_filter` and
`delete_placeholder_point` would have produced HTTP 400 on Cloud
instances even after this PR's KEYWORD fix.
Implementation: replace `_KEYWORD_PAYLOAD_FIELDS: tuple` with
`_PAYLOAD_INDEX_FIELDS: dict[str, PayloadSchemaType]` so each
field carries its own schema type. Rename
`_ensure_keyword_payload_indexes` to `_ensure_payload_indexes` since
the function now creates more than just KEYWORD indexes. The
per-field log line now includes the schema type
("Created KEYWORD payload index on 'doc_id'", "Created BOOL payload
index on 'is_placeholder'") so operators can tell which type was
created without checking the source.
- Correct the misleading `wait=True` docstring in
`_apply_backfill_writes`. The previous wording said
`_ensure_payload_indexes` runs "immediately after this function",
but `_apply_backfill_writes` is called in a loop inside
`_backfill_doc_id_to_string` — the index creation runs after the
backfill function *returns*, not after each write. Rewrote the
docstring to capture both load-bearing reasons:
(1) per-batch commit ordering for crash-recovery safety, and
(2) ensuring the keyword index built later covers committed
payloads only.
Adds `test_ensure_payload_indexes_includes_is_placeholder_as_bool`
asserting the schema type is BOOL specifically. Existing tests
updated to use the new dict-based registry (side_effect lists now
extend to all four entries; field-set assertions derive from the
registry instead of hardcoding 3 KEYWORD names).

fix(vector): address PR review round 6 + SonarCloud findings
Reviewer feedback (3 important + 3 nits):
- Wrap _ensure_keyword_payload_indexes' get_collection() call in
try/except. The qdrant_client singleton is already assigned by the
time this function runs, so a transient timeout/DNS failure
propagating out left the process holding a usable client with the
migration silently skipped on every subsequent call. Now logs ERROR
with exc_info and returns; next process restart retries.
- Add `and "doc_id" in point.payload` guard to the four set
comprehensions in scanner.py (indexed_doc_ids, indexed_file_ids,
indexed_item_ids, indexed_card_ids). Previously a payload missing
the doc_id key would raise KeyError and crash the entire scan.
- Tighten test_ensure_keyword_payload_indexes_logs_400_as_warning to
match the per-field warning prefix exactly (`startswith("Schema
conflict on payload index")`), so a future change adding 400s to
the partial-failure summary surfaces here as a count mismatch.
- Add new-collection vs existing-collection context to the
_backfill_doc_id_to_string docstring's `dimension` parameter.
- Replace the misleading "rewrote 0/N from int to str" wording when
no rewriting was needed with "N points scanned, none required
rewriting (collection already in str form)".
- Add test_ensure_keyword_payload_indexes_logs_and_returns_when_
get_collection_raises mirroring the scroll-failure test.
SonarCloud (1 CRITICAL + 1 MINOR):
- Refactor _backfill_doc_id_to_string to bring cognitive complexity
under 15 (was 19). Extracted two pure helpers: _group_int_doc_ids
(group point IDs by stringified doc_id) and _apply_backfill_writes
(apply set_payload calls and return rewritten count). The main
function's scroll/loop/sentinel structure is unchanged.
- Add `await asyncio.sleep(0)` to the three async test side_effect
helpers (_scroll_raises, _upsert_raises, _create_index) so they use
an actual async feature (S7503). The async-callable shape is still
required to avoid the AsyncMock unawaited-coroutine warning when
side_effect raises.

fix(vector): address PR review round 5 — progress logging, summary visibility, sentinel split
Addresses three important findings from the latest reviewer comment: - Add progress INFO log every 20 scroll batches (≈5120 points at batch_size=256) in _backfill_doc_id_to_string so a long-running migration on a large collection (50k+ points) doesn't look like a startup hang. The line carries collection name, scanned count, and rewritten count so it doubles as a heartbeat. - Track non-400 failures in _ensure_keyword_payload_indexes and emit a WARNING summary line listing every field that failed to get an index. Per-field ERROR lines are easy to miss in startup noise; the summary makes the partial-failure state visible at a glance. - Split the sentinel upsert out of the data-scroll try/except in _backfill_doc_id_to_string. A scroll-time failure still logs ERROR with the new "scroll failed" wording (data is incomplete). A sentinel-write failure now logs WARNING with "data succeeded but sentinel write failed" wording — data is correct, only the short-circuit marker is missing, and the next restart re-scrolls an already-clean collection (idempotent zero-write) before retrying the upsert. Also fix the RuntimeWarning emitted by test_backfill_logs_and_returns_when_scroll_raises: replace the bare `RuntimeError` side_effect with an async-callable side_effect so AsyncMock awaits the coroutine before the exception propagates. Three new unit tests cover the new branches: test_backfill_emits_progress_log_every_20_batches, test_backfill_logs_warning_when_sentinel_upsert_fails, test_ensure_keyword_payload_indexes_summarises_failed_fields.

fix(vector): address PR review round 4 — backfill resilience + degraded-mode docs
- Remove three stale `# Use numeric file ID` / `# Pass file path` comments in scanner.py. file_id is already normalized to str() above each call site, so the inline comments mislead readers. - Wrap `_backfill_doc_id_to_string` scroll loop + sentinel upsert in try/except Exception. The qdrant_client singleton is assigned before this migration runs, so a transient scroll failure was leaving the process holding a usable client with int payloads permanently unbackfilled until the next restart. Catch broadly, log ERROR with exc_info, and return without writing the sentinel — next process restart retries from scratch. - Note `:memory:` mode behavior near the sentinel constants so future readers don't read the every-start scroll as a bug. - Document the two degraded-migration ERROR log signals in docs/configuration.md so operators know when a clean restart is required to recover indexing. - Add unit test asserting scroll-time exceptions are logged and swallowed without writing the sentinel.

fix(vector): address PR review round 3 — sentinel guard, skip indexed fields, narrow types
- Add a fixed-UUID sentinel point written after a successful doc_id backfill so subsequent restarts retrieve it and short-circuit the O(N) scroll. Sentinel has no user_id/doc_id/doc_type payload so production search filters never see it. - Pre-fetch payload_schema in _ensure_keyword_payload_indexes and silently skip fields that are already indexed; the "Created KEYWORD payload index" INFO log fires only on actual creation. - Narrow stale `int | str` doc_id annotations to `str` across search/verification.py (BatchVerifier return type, per-verifier accessible sets, by_type / accessible_by_type / inaccessible collections); drop the now-redundant `type(d).__name__` prefix in the dropped-docs log. - Align the backfill log message with the PR description's "Running doc_id backfill" promise; add a caller cross-reference to the wait=True comment. - Fix _get_file_path_from_qdrant docstring (file_id is str, not numeric). - Convert legacy `id=1` to `id="1"` in test_search_result.py to match the SearchResult.id: str annotation. Three new unit tests cover sentinel-found, sentinel-written, and skip-existing-index branches; existing backfill tests pass dimension and explicit retrieve.return_value=[] for the no-sentinel path.

fix(vector): address PR review round 2 — status branching, doc_id guard, doc restore
- _ensure_keyword_payload_indexes: distinguish 400 (schema conflict, warning)
from other status codes (5xx/network, error) so a transient outage doesn't
silently leave the collection unindexed.
- build_search_result_from_point: use .get("doc_id") + return None on missing
instead of KeyError-crashing the search; reverse metadata merge order so
payload-derived chunk_index/total_chunks win over caller-supplied extras.
- docs/configuration.md: restore the OpenAI/Mistral/Bedrock/Simple provider
sections + reference-table rows that were dropped in the rebase. Reword
the "Startup migrations" bullet to describe what the code actually does
(no sampling — full scroll, zero writes when clean). Add operator note
about the SemanticSearchResult.id TypeError path.
- tests: pytest.approx for float equality (Sonar python:S1244); coverage
for non-400 → ERROR, payload={doc_id: None}, and missing doc_id key.

fix(vector): address PR review — wait=True backfill, batched writes, search helper
Addresses reviewer feedback on PR #773: - Backfill set_payload now uses wait=True to avoid a race where _ensure_keyword_payload_indexes builds the KEYWORD index before fire-and-forget writes have committed, leaving int payloads invisible to filters. - Batch points sharing the same int doc_id into a single set_payload call (one document → many chunks → one round-trip instead of N). - Drop _has_int_doc_id_sample short-circuit. The sample's false-negative window (clean first 256 results, ints further in) is gone; full scroll is the dominant cost on first run anyway. - Simplify _ensure_keyword_payload_indexes: the "already exists" 400 branch was dead code (Qdrant returns 200 on identical re-create); any 400 now logs a warning and continues. - search/context.py: comment the broadened file-type guard. Add explicit not doc_id.isdigit() checks at the top of note/news_item/deck_card branches in _fetch_document_text so malformed payloads surface as warnings instead of being swallowed by the broad except. Also extracts build_search_result_from_point into search/algorithms.py to deduplicate the 71-line payload-extraction loop shared by SemanticSearchAlgorithm and BM25HybridSearchAlgorithm. This fixes SonarQube's quality-gate failure (4.0% new-code duplication, max 3%). Test coverage: - 7 new unit tests for build_search_result_from_point covering missing payload, note/file/deck_card metadata, int doc_id coercion, and metadata_extras merging. - Replace _has_int_doc_id_sample tests with clean-collection no-op and per-batch grouping tests. - Update set_payload assertions from wait=False to wait=True.

fix(vector): normalize doc_id to str + add Qdrant keyword payload indexes
Production was logging two cascading classes of Qdrant errors against the
welcomed-malamute deployment:
1. HTTP 400 — "Bad request: Index required but not found for \"doc_id\" of
one of the following types: [keyword]". The collection was created via
create_collection() with no payload indexes, so any FieldCondition
filter on doc_id failed at the Qdrant layer (placeholder writes/reads,
eviction, search context lookups).
2. Compounding the missing index, producers wrote a mix of int and str
doc_ids: webhook_parser stringified node_id, scanner stringified note
IDs, news IDs, and deck card IDs — but the file scanner passed the
numeric file_id through unchanged. A keyword index would not have
covered both kinds even if it had existed.
This change:
- Normalizes doc_id to str at every producer site (scanner.py:459,
DocumentTask.doc_id, indexed_*_ids reads from Qdrant).
- Tightens str|int annotations to str across placeholder.py,
eviction.py, search/verification.py, search/context.py,
SearchResult.id, and the auth/api visualization endpoints.
- Defensive str() coercion on doc_id reads in semantic.py /
bm25_hybrid.py / vector/visualization.py for the transition window
before the backfill runs.
- Adds an idempotent startup migration in get_qdrant_client():
- _ensure_keyword_payload_indexes creates KEYWORD indexes for
doc_id, user_id, and doc_type (tolerates "already exists" 400s).
- _backfill_doc_id_to_string scrolls the collection once and rewrites
int doc_ids to str. Skipped after a quick sample shows no legacy
int payloads.
- Public API preserved: SemanticSearchResult.id stays int via explicit
int(r.id) narrowing in server/semantic.py — surfaces a TypeError with
actionable context if a future doc_type ships non-numeric ids.
- Documents the startup migration in docs/configuration.md.
Tests: 11 new unit tests in tests/unit/vector/test_qdrant_client.py
covering happy path / already-exists / unrelated-400 for the index
helpers, and sample-skip / mixed-batch rewrite / payload=None edge cases
for the backfill. 889 unit tests pass.

feat(vector): Support multiple embedding models with auto-generated collection names
This PR enables safe switching between embedding models and multi-server
deployments by implementing auto-generated Qdrant collection names based on
deployment ID and model name.
## Problem
Previously, all deployments used a single hardcoded collection name
"nextcloud_content", which caused two critical issues:
1. **Dimension mismatches when switching models**: Changing
OLLAMA_EMBEDDING_MODEL (e.g., nomic-embed-text at 768D → all-minilm at
384D) would cause runtime errors as vectors couldn't be inserted into a
collection with incompatible dimensions.
2. **Collection collisions in multi-server setups**: Multiple MCP servers
sharing a single Qdrant instance would overwrite each other's data,
making horizontal scaling impossible.
## Solution
### Auto-Generated Collection Naming
Collections are now automatically named using the pattern:
\`{deployment-id}-{model-name}\`
**Deployment ID**: Uses \`OTEL_SERVICE_NAME\` if configured (and not default
value), otherwise falls back to \`hostname\` for simple Docker deployments.
**Model Name**: From \`OLLAMA_EMBEDDING_MODEL\` with path separators sanitized.
**Examples**:
- \`my-mcp-server-nomic-embed-text\` (with OTEL_SERVICE_NAME=my-mcp-server)
- \`mcp-container-all-minilm\` (simple Docker, hostname=mcp-container)
**Override**: Users can still set \`QDRANT_COLLECTION\` explicitly to bypass
auto-generation for backward compatibility.
### Dimension Validation
Added startup validation that checks collection dimensions match the
embedding service. If a mismatch is detected, the server fails fast with a
clear error message explaining:
- Expected vs actual dimensions
- Likely cause (model change)
- Solutions (delete collection, use different name, or revert model)
### Improved Sampling Error Handling
Enhanced MCP sampling rejection handling to treat user rejections as normal
behavior rather than errors:
- **User rejections** ("rejected", "denied") → INFO log, no traceback
- **Unsupported clients** → INFO log, no traceback
- **Other MCP errors** → WARNING log, no traceback
- **Unexpected errors** → ERROR log WITH traceback
This aligns with the MCP specification where clients SHOULD prompt users for
approval/denial of sampling requests.
## Changes
### Core Implementation
- **nextcloud_mcp_server/config.py**: Added \`get_collection_name()\` method
with deployment ID detection and model name sanitization
- **nextcloud_mcp_server/vector/qdrant_client.py**: Dimension validation on
collection open with helpful error messages
- **nextcloud_mcp_server/vector/{scanner,processor}.py**: Updated to use
\`get_collection_name()\`
- **nextcloud_mcp_server/auth/userinfo_routes.py**: Vector sync status uses
\`get_collection_name()\`
- **nextcloud_mcp_server/server/semantic.py**:
- Updated semantic search tools to use \`get_collection_name()\`
- Improved sampling rejection error handling (McpError vs Exception)
### Documentation
- **docs/semantic-search-architecture.md**: New comprehensive architecture
document (557 lines) covering background sync, semantic search flow, RAG
implementation, and deployment modes
- **docs/configuration.md**: Added detailed "Qdrant Collection Naming"
section with examples and multi-server deployment guidance
- **docker-compose.yml**: Added comments explaining collection naming behavior
- **README.md**: Updated semantic search descriptions to clarify
experimental status, Notes-only support, and infrastructure requirements
## Migration Guide
**For existing single-server deployments:**
Option 1 (Recommended): Use explicit collection name for continuity
\`\`\`bash
QDRANT_COLLECTION=nextcloud_content # Keep existing collection
\`\`\`
Option 2: Allow auto-generation and re-embed
\`\`\`bash
# Remove QDRANT_COLLECTION override
# New collection will be created based on deployment ID + model
# Requires re-embedding all documents (may take time)
\`\`\`
**For new multi-server deployments:**
Set unique OTEL service names per server:
\`\`\`bash
# Server 1
OTEL_SERVICE_NAME=mcp-prod
OLLAMA_EMBEDDING_MODEL=nomic-embed-text
# → Collection: "mcp-prod-nomic-embed-text"
# Server 2
OTEL_SERVICE_NAME=mcp-staging
OLLAMA_EMBEDDING_MODEL=nomic-embed-text
# → Collection: "mcp-staging-nomic-embed-text"
\`\`\`
## Benefits
✅ **Safe model switching**: Each model gets its own collection, preventing
dimension mismatch errors
✅ **Multi-server support**: Multiple MCP servers can share one Qdrant
instance without conflicts
✅ **Clear ownership**: Collection names show which deployment and model owns
the data
✅ **Better error messages**: Dimension validation provides actionable
guidance
✅ **Backward compatible**: Existing deployments can continue using
\`QDRANT_COLLECTION\` override
## Testing
Validated with:
- Single-server deployments (default hostname-based naming)
- Multi-server deployments (OTEL service name-based naming)
- Model switching scenarios (dimension validation)
- Collection override scenarios (backward compatibility)
Next steps: Testing various Ollama embedding models to investigate optimal
chunk sizes and performance characteristics.

feat: add Qdrant local mode support with in-memory and persistent storage
Adds flexible Qdrant deployment modes to reduce infrastructure requirements
for local development and smaller deployments:
**Configuration Changes:**
- Add QDRANT_LOCATION environment variable (mutually exclusive with QDRANT_URL)
- Three modes: network (URL), in-memory (:memory:, default), persistent (file path)
- Settings dataclass validation via __post_init__ ensures mutual exclusivity
- API key warning when set in local mode (ignored, only for network mode)
**Client Initialization:**
- Auto-detect mode: network (url + api_key) vs local (:memory: or path=)
- In-memory: AsyncQdrantClient(":memory:") - zero config default
- Persistent: AsyncQdrantClient(path="/app/data/qdrant") - file storage
- Network: AsyncQdrantClient(url, api_key) - production mode
**Docker Compose Updates:**
- Qdrant service moved to optional profile (--profile qdrant)
- MCP service uses QDRANT_LOCATION=:memory: by default
- Added mcp-data volume for persistent storage (/app/data)
- No hard dependency on qdrant service
**Documentation:**
- Comprehensive configuration guide in docs/configuration.md
- All three modes documented with pros/cons
- Docker Compose examples for each mode
- Environment variable reference table
**Tests:**
- 13 new config validation tests (mutual exclusivity, defaults, warnings)
- Persistent mode integration test (create, close, reopen, verify persistence)
- All 82 unit tests + 5 smoke tests pass
**Breaking Change:**
- Default changed from QDRANT_URL=http://qdrant:6333 to QDRANT_LOCATION=:memory:
- Simplifies local development (no external service needed)
- Production deployments: explicitly set QDRANT_URL or QDRANT_LOCATION

Scanner Implementation: - Periodic document discovery (hourly, configurable) - Timestamp-based change detection (Nextcloud vs Qdrant) - Wake event for immediate scanning on-demand - Supports both initial sync (all docs) and incremental sync (changes only) - Detects deleted documents and queues for removal Processor Implementation: - Concurrent document processing pool (3 workers default) - I/O-bound embedding generation via Ollama API - Retry logic with exponential backoff (3 retries) - Document chunking (512 words, 50-word overlap) - Handles both index and delete operations - Upserts vectors to Qdrant with rich metadata App Lifespan Integration: - Extended AppContext with background task state - Modified app_lifespan_basic() to start tasks via anyio TaskGroups - Graceful shutdown with coordinated task cancellation - Only activates when VECTOR_SYNC_ENABLED=true Embedding Service: - OllamaEmbeddingProvider with TLS support - Singleton pattern for shared client instances - Batch embedding support for efficiency - Auto-detects embedding dimension (768 for nomic-embed-text) Qdrant Client: - Async client wrapper with singleton pattern - Auto-creates collection on first use - COSINE distance metric for semantic similarity - Integrates with embedding service for dimension detection Health Check Enhancement: - Added Qdrant status check to /health/ready endpoint - Only checks when VECTOR_SYNC_ENABLED=true - 2-second timeout for health probe - Reports connection errors with details Configuration: - VECTOR_SYNC_ENABLED: Enable background sync - VECTOR_SYNC_SCAN_INTERVAL: Scanner frequency (3600s default) - VECTOR_SYNC_PROCESSOR_WORKERS: Concurrent processors (3 default) - QDRANT_URL, QDRANT_API_KEY, QDRANT_COLLECTION: Vector DB config - OLLAMA_BASE_URL, OLLAMA_EMBEDDING_MODEL: Embedding service config Dependencies Added: - qdrant-client>=1.7.0: Vector database client Docker Compose: - Added Qdrant service with health check - Exposed ports 6333 (REST) and 6334 (gRPC) - Configured MCP service with vector sync environment - Added qdrant-data volume for persistence Known Issue: - FastMCP lifespan not triggering for streamable-http transport - Background tasks will start once lifespan integration is complete - Lifespan triggers on MCP session establishment, not server startup Related: ADR-007 Background Vector Database Synchronization 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
