Chris CoutinhoandClaude Sonnet 4.5 dd42849d70 feat(helm): migrate to new environment variable naming convention
Replace deprecated environment variables with new consolidated names:
- VECTOR_SYNC_ENABLED → ENABLE_SEMANTIC_SEARCH
- ENABLE_OFFLINE_ACCESS → ENABLE_BACKGROUND_OPERATIONS

Update values.yaml structure:
- Rename 'vectorSync' section to 'semanticSearch'
- Update descriptions to emphasize BM25 hybrid search

Benefits:
- Aligns with application-level config consolidation
- Clearer naming: "semantic search" vs "vector sync"
- Maintains backward compatibility via application deprecation handling
- Automatic enablement of background ops when semantic search enabled in multi-user modes

Updated files:
- values.yaml: Renamed vectorSync → semanticSearch
- deployment.yaml: New env var names with deprecation comments
- NOTES.txt: Updated deployment notes
- README.md: Updated documentation and examples

Chris CoutinhoandClaude Sonnet 4.5 8ba3ae73ab fix(helm): set OIDC client env vars when using existingSecret
The deployment template only checked for clientId being set in
values.yaml, so when using existingSecret without setting clientId,
the NEXTCLOUD_OIDC_CLIENT_ID and NEXTCLOUD_OIDC_CLIENT_SECRET env
vars were never created.

This broke existingSecret for OIDC-based auth - the server would
always fall back to DCR even when pre-registered credentials were
provided via secret.

Fix: Check for EITHER clientId OR existingSecret being set before
creating the OIDC client credential env vars.

Affects both OIDC-based auth modes:
- auth.oauth.existingSecret (OAuth mode)
- auth.multiUserBasic.existingSecret (multi-user BasicAuth with offline access)

Chris Coutinho ea96a58678 fix(helm): address PR #447 reviewer feedback
Critical fix:
- deployment.yaml: Only reference OAuth credentials when clientId is set
- Fixes pod failure when using existingSecret without static OAuth creds
- Aligns deployment behavior with secret template logic

Previously, the deployment referenced OAuth credentials when either
clientId OR existingSecret was set. However, the secret template only
includes OAuth credentials when clientId is explicitly provided. This
caused pod failures when users provided an existingSecret for offline
access without static OAuth credentials (intending to use DCR).

The fix ensures OAuth env vars are only referenced when clientId is set,
matching the OAuth mode pattern and allowing DCR to work correctly with
existingSecret configurations.

Minor improvements:
- values.yaml: Clarify OAuth credentials are optional (uses DCR if not provided)

Testing verified all scenarios:
 Pass-through only (no offline access): No secrets/PVCs/OAuth vars
 Offline + DCR (no clientId): Secret with encryption key only, no OAuth vars
 Offline + static OAuth: Secret with all keys, OAuth vars present
 existingSecret without clientId: No auto secret, no OAuth vars (FIXED)

Resolves reviewer feedback from PR #447

Chris Coutinho 04140d671e feat(helm): add support for multi-user BasicAuth mode
Adds multi-user-basic authentication mode to the helm chart alongside
existing basic (single-user) and oauth modes.

Multi-user BasicAuth mode enables:
- Pass-through authentication (credentials in request headers)
- Optional background operations using app passwords via Astrolabe
- Optional OAuth client credentials (uses DCR if not provided)
- Token encryption and persistent storage for background sync

Changes:
- values.yaml: Add auth.multiUserBasic configuration section
- deployment.yaml: Add ENABLE_MULTI_USER_BASIC_AUTH and related env vars
- secret.yaml: Add secret template for token encryption key and OAuth credentials
- pvc.yaml: Add PVC template for token database persistence
- _helpers.tpl: Add helper functions for secret/PVC names

Tested with:
  helm template --set auth.mode=multi-user-basic \
    --set auth.multiUserBasic.enableOfflineAccess=true \
    --set auth.multiUserBasic.tokenEncryptionKey=... \
    --set vectorSync.enabled=true

Chris CoutinhoandClaude a6e5f3d8ff refactor: simplify OpenTelemetry tracing configuration
Simplifies the OpenTelemetry tracing setup by removing the redundant
OTEL_ENABLED flag and using the presence of OTEL_EXPORTER_OTLP_ENDPOINT
to determine if tracing should be enabled. This follows the standard
OpenTelemetry environment variable conventions more closely.

Changes:
- Remove OTEL_ENABLED/tracing_enabled flag in favor of checking if
  OTEL_EXPORTER_OTLP_ENDPOINT is set
- Add OTEL_EXPORTER_VERIFY_SSL configuration option for OTLP endpoints
  with self-signed certificates (defaults to false for development)
- Move HTTPXClientInstrumentor initialization to module level to ensure
  httpx calls are traced across all Nextcloud API requests
- Add tracing spans to vector sync operations (scan_user_documents)
- Fix authorization header logging to only warn about missing headers
  in OAuth mode (BasicAuth mode doesn't use Authorization headers)
- Update observability documentation to reflect simplified configuration
- Refactor Dockerfile to use --no-editable flag for uv sync

Breaking changes:
- OTEL_ENABLED environment variable is removed
- Tracing is now automatically enabled when OTEL_EXPORTER_OTLP_ENDPOINT
  is set

Migration guide:
- Remove OTEL_ENABLED=true from environment configuration
- Tracing will be enabled automatically if OTEL_EXPORTER_OTLP_ENDPOINT
  is configured

Chris CoutinhoandClaude d80e54ff97 feat(helm): Add document chunking configuration
Add support for configurable document chunking parameters to Helm chart
to match docker-compose and application capabilities.

Changes:
1. values.yaml:
   - Add documentChunking section with chunkSize (512) and chunkOverlap (50)
   - Include comprehensive comments explaining chunking strategies
   - Positioned between vectorSync and qdrant sections

2. templates/deployment.yaml:
   - Add DOCUMENT_CHUNK_SIZE and DOCUMENT_CHUNK_OVERLAP env vars
   - Always set (not conditional), used by vector sync processor
   - Environment variables follow same pattern as config.py defaults

3. README.md:
   - Add documentChunking parameter table in Vector Search section
   - Document chunking strategies (small/medium/large chunks)
   - Explain overlap recommendations (10-20% of chunk size)

Validation:
- helm lint: Passes
- helm template: Environment variables correctly generated
- Custom values: Work as expected (tested with chunkSize=1024)
- Always present: Not conditional on vectorSync.enabled

This maintains feature parity between Helm and docker-compose deployments,
allowing users to tune chunking for their embedding models and use cases.

Chris CoutinhoandClaude 167e49788e feat(helm): add Qdrant local mode support with three deployment options [skip ci]
Add support for three Qdrant deployment modes in Helm chart:
1. In-memory mode (:memory:) - Default, zero-config, ephemeral storage
2. Persistent local mode (path-based) - File-based storage with PVC
3. Network mode (URL-based) - Dedicated Qdrant service or external instance

Changes:
- Restructured qdrant configuration in values.yaml with mode selector
- Added conditional environment variable logic in deployment.yaml
- Created PVC template for persistent local mode with optional existingClaim
- Added qdrantPvcName helper template in _helpers.tpl
- Updated README.md with Helm registry URL (https://cbcoutinho.github.io/nextcloud-mcp-server)

Breaking change: Default changed from requiring qdrant.enabled to using
in-memory mode (:memory:) when no Qdrant configuration is provided.

Chris CoutinhoandClaude 23360485a8 refactor: Remove NEXTCLOUD_OIDC_CLIENT_STORAGE environment variable
Remove the NEXTCLOUD_OIDC_CLIENT_STORAGE environment variable from all
configuration files. OAuth client credentials are now always stored in the
SQLite database, with no option to use a custom JSON file path.

Changes:
- Remove NEXTCLOUD_OIDC_CLIENT_STORAGE from .env.keycloak.sample
- Remove NEXTCLOUD_OIDC_CLIENT_STORAGE from docker-compose.yml (mcp-oauth and mcp-keycloak services)
- Remove NEXTCLOUD_OIDC_CLIENT_STORAGE from Helm deployment template
- Remove NEXTCLOUD_OIDC_CLIENT_STORAGE from test_cli.py test assertions
- Remove --headed flag from pytest addopts (use CLI arg instead)

This simplifies configuration by enforcing a single storage mechanism
(SQLite database) for OAuth client credentials.
