Summary

This PR introduces a database abstraction layer using the Repository Pattern, enabling Archon to support multiple database backends without modifying business logic.

Key Features

  • 3 Backend Support: Supabase (existing), PostgreSQL (new), InMemory (tests)
  • Clean Architecture: Domain interfaces + Infrastructure implementations
  • Dependency Injection: Container singleton with async lifecycle
  • Multi-dimension Embeddings: 768, 1024, 1536, 3072 support
  • 102 Unit Tests: All passing (0.91s execution)

Architecture

Application Layer (FastAPI, MCP)
         |
    Container (DI)
         |
   Domain Layer (Interfaces + Models)
         |
Infrastructure Layer (Supabase | PostgreSQL | InMemory)

Configuration

# Supabase (default - no change for existing users)
export REPOSITORY_TYPE=supabase

# PostgreSQL (self-hosted alternative)
export REPOSITORY_TYPE=postgres
export POSTGRES_HOST=localhost

# InMemory (fast unit tests)
export REPOSITORY_TYPE=memory

Files Changed

Category Files Lines
Domain (interfaces + models) 10 ~460
Infrastructure (3 backends) 12 ~1,650
Container & Factory 2 ~380
Tests 9 ~1,200
Documentation 2 ~700
Total 41 ~7,500

Test Plan

  • 102 unit tests pass locally
  • InMemory backend tested extensively
  • Container lifecycle tested (init/shutdown)
  • Contract tests verify interface compliance
  • Integration tests with real PostgreSQL (CI)
  • Integration tests with real Supabase (CI)

Breaking Changes

None. Existing Supabase users continue working without any changes. The abstraction layer is additive.

Poem

🐰 I hopped into code with a twitchy nose,
Buried vectors, nests of repos in tidy rows.
Container hums, backends snug in bed,
Tests hop by moonlight, keeping bugs well-fed.
Cheers — the data burrow springs ahead!

23-57: Add language identifiers to code blocks.

Lines 23 and 527 contain fenced code blocks without language specifications. While the ASCII diagrams render correctly, adding language identifiers improves markdown linting compliance.

🔎 Proposed fix for missing code block language identifiers
-```
+```text
 +------------------------------------------------------------------+
 |                        APPLICATION LAYER                          |

52-52: Add language identifiers to fenced code blocks.

Multiple code blocks lack language specifications, violating markdown linting rules (MD040). This affects lines 52, 89, 187, and 429.

🔎 Proposed fix example

For line 52 (diagram):

-```

412-412: Use a proper heading instead of emphasis.

Line 412 uses emphasis (**...**) for what should be a section heading. This violates the MD036 rule.

1-485: Consider aligning documentation language with the PR.

This refactoring status report is written entirely in French, while DATABASE_ABSTRACTION.md and the broader PR are in English. This creates inconsistency in the documentation set.

Recommendation: Either translate this report to English for consistency, or clarify if it's intended as a French-language artifact for a French-speaking audience. If translation is planned, I can assist.

Would you like me to help translate this status report to English or clarify the intended audience for this document?

python/src/server/domain/interfaces/sources_repository.py (1)

121-130: Consider using an enum for status values.

The status parameter accepts a bare string with documented values (pending, crawling, completed, failed). A SourceStatus enum would provide compile-time safety and auto-completion. This is optional as the current approach is flexible.

python/tests/unit/repositories/test_sources_repository.py (1)

122-138: Potential flakiness with timestamp ordering test.

Using asyncio.sleep(0.01) to ensure different timestamps could be flaky on slow systems or under load. Consider using explicit timestamps if the repository implementation supports it, or increase the sleep duration for more reliability.

python/src/server/infrastructure/memory/vector_utils.py (1)

57-77: Consider adding empty vector validation for consistency.

While mathematically valid, euclidean_distance allows empty vectors (returns 0.0) but cosine_similarity raises ValueError. For API consistency, consider adding the same empty vector check here.

🔎 Proposed validation addition
 def euclidean_distance(vec_a: Sequence[float], vec_b: Sequence[float]) -> float:
     """
     Calculate Euclidean distance between two vectors.
 
     Args:
         vec_a: First vector
         vec_b: Second vector
 
     Returns:
         Euclidean distance (lower = more similar)
 
     Raises:
         ValueError: If vectors have different lengths
     """
     if len(vec_a) != len(vec_b):
         raise ValueError(
             f"Vectors must have same length: {len(vec_a)} != {len(vec_b)}"
         )
+
+    if len(vec_a) == 0:
+        raise ValueError("Vectors cannot be empty")
 
     sum_squared_diff = sum((a - b) ** 2 for a, b in zip(vec_a, vec_b))
     return math.sqrt(sum_squared_diff)
python/src/server/infrastructure/memory/crawled_pages_repository.py (3)

17-18: Document rationale for low similarity threshold.

The SIMILARITY_THRESHOLD = 0.05 is very permissive (5% similarity). Consider documenting why such a low threshold is appropriate for in-memory testing, or making it configurable if different test scenarios need different thresholds.


38-52: Consider reusing domain model's get_embedding method.

The _get_embedding helper duplicates logic from CrawledPage.get_embedding() method (seen in domain model). Consider calling the domain model method directly to avoid duplication.

🔎 Proposed refactor to reuse domain method
 def _get_embedding(self, page: CrawledPage) -> list[float] | None:
     """Get the active embedding from a page based on its dimension."""
-    if page.embedding_dimension == 768:
-        return page.embedding_768
-    elif page.embedding_dimension == 1024:
-        return page.embedding_1024
-    elif page.embedding_dimension == 1536:
-        return page.embedding_1536
-    elif page.embedding_dimension == 3072:
-        return page.embedding_3072
-    # Fallback: try to find any available embedding
-    return (
-        page.embedding_1536 or page.embedding_768 or
-        page.embedding_1024 or page.embedding_3072
-    )
+    return page.get_embedding()

130-178: Handle unsupported embedding dimensions explicitly.

The insert method silently ignores embeddings with unsupported dimensions (not 768/1024/1536/3072). Consider logging a warning or raising an error to catch configuration issues early.

🔎 Proposed validation for embedding dimension
 # Determine which embedding column to use
 embedding_768 = None
 embedding_1024 = None
 embedding_1536 = None
 embedding_3072 = None

 if page.embedding and page.embedding_dimension:
     if page.embedding_dimension == 768:
         embedding_768 = page.embedding
     elif page.embedding_dimension == 1024:
         embedding_1024 = page.embedding
     elif page.embedding_dimension == 1536:
         embedding_1536 = page.embedding
     elif page.embedding_dimension == 3072:
         embedding_3072 = page.embedding
+    else:
+        raise ValueError(
+            f"Unsupported embedding dimension: {page.embedding_dimension}. "
+            f"Supported dimensions: 768, 1024, 1536, 3072"
+        )
python/src/server/domain/models/source.py (1)

34-35: Consider adding URL validation.

The url field accepts any string without format validation. While domain models are often kept lean, adding basic URL validation could prevent invalid data from entering the system early.

🔎 Optional: Add URL validation
 from pydantic import BaseModel, Field
+from pydantic import HttpUrl

 class Source(BaseModel):
     source_id: str = Field(..., description="Unique source identifier")
-    url: str = Field(..., description="Base URL of the source")
+    url: HttpUrl = Field(..., description="Base URL of the source")

Alternatively, you can use a custom validator if you need more flexible URL formats:

from pydantic import field_validator

class Source(BaseModel):
    # ... fields ...
    
    @field_validator('url')
    @classmethod
    def validate_url(cls, v: str) -> str:
        if not v.startswith(('http://', 'https://')):
            raise ValueError('URL must start with http:// or https://')
        return v
python/src/server/infrastructure/supabase/crawled_pages_repository.py (3)

173-184: Duplicated embedding column selection logic.

The dimension-to-column mapping appears in both insert and insert_batch. Consider extracting a helper method.

🔎 Proposed helper
def _get_embedding_column(self, dimension: int | None) -> str | None:
    """Map embedding dimension to column name."""
    return {768: "embedding_768", 1024: "embedding_1024", 

Also applies to: 222-233


303-310: Count query fetches all columns unnecessarily.

Using select("*", count="exact") retrieves all rows. For a pure count, select a minimal column to reduce payload.

🔎 Suggested optimization
-            query = self.client.table(self.table_name).select("*", count="exact")
+            query = self.client.table(self.table_name).select("id", count="exact")

42-44: Move json import to module level for consistency.

The lazy import inside _row_to_model works but differs from other repository files that import json at the top.

python/src/server/infrastructure/memory/sources_repository.py (1)

100-115: update mutates the caller's updates dict.

Line 109 modifies the dict passed by the caller by adding updated_at. This side effect could be unexpected. Consider working on a copy.

🔎 Suggested fix
     async def update(self, source_id: str, updates: dict[str, Any]) -> Source | None:
         """Update an existing source."""
         with self._lock:
             source = self._sources.get(source_id)
             if not source:
                 return None

             # Create updated source
             source_dict = source.model_dump()
-            source_dict.update(updates)
-            source_dict["updated_at"] = datetime.now(timezone.utc)
+            source_dict.update({**updates, "updated_at": datetime.now(timezone.utc)})

             updated_source = Source(**source_dict)
             self._sources[source_id] = updated_source

             return updated_source
python/src/server/infrastructure/repository_factory.py (1)

146-266: Significant code duplication across factory functions.

get_crawled_pages_repository, get_sources_repository, and get_code_examples_repository share identical storage-type switching logic. Consider a generic factory helper or table-driven approach.

🔎 Conceptual refactor using a registry
_REPOSITORY_REGISTRY = {
    "crawled_pages": {
        "supabase": ("supabase.crawled_pages_repository", "SupabaseCrawledPagesRepository"),
        "postgres": ("postgres", "PostgresCrawledPagesRepository"),
        "memory": ("memory", "InMemoryCrawledPagesRepository"),
    },
    # ... similar for sources, code_examples
}

def _create_repository(repo_type: str, storage_type: str):
    module_path, class_name = _REPOSITORY_REGISTRY[repo_type][storage_type]
    # dynamic import and instantiation
python/src/server/infrastructure/postgres/sources_repository.py (1)

278-280: Fragile parsing of DELETE result.

Parsing result.split()[-1] relies on asyncpg's "DELETE N" format. Consider a more defensive approach or document this assumption.

🔎 Safer parsing
-                # Parse "DELETE X" to get count
-                deleted_count = int(result.split()[-1])
+                # asyncpg returns "DELETE N" where N is affected rows
+                try:
+                    deleted_count = int(result.split()[-1])
+                except (ValueError, IndexError):
+                    self._logger.warning(f"Unexpected DELETE result format: {result}")
+                    deleted_count = 0
python/src/server/infrastructure/supabase/sources_repository.py (2)

158-180: update mutates the caller's updates dict.

Line 162 adds updated_at directly to the passed dict, which could surprise callers. Consider working on a copy for consistency with expected behavior.

🔎 Suggested fix
     async def update(self, source_id: str, updates: dict[str, Any]) -> Source | None:
         """Update an existing source."""
         try:
             # Add updated_at timestamp
-            updates["updated_at"] = datetime.now(timezone.utc).isoformat()
+            updates = {**updates, "updated_at": datetime.now(timezone.utc).isoformat()}

             response = (
                 self.client.table(self.table_name)
                 .update(updates)

250-256: Count query fetches all columns unnecessarily.

Same optimization opportunity as in SupabaseCrawledPagesRepository—select a minimal column instead of "*".

python/src/server/infrastructure/supabase/code_examples_repository.py (3)

39-62: Consider moving the JSON import to module level.

The import json inside _row_to_model works but is unconventional. Moving it to the module's import section improves clarity and avoids repeated import lookups.

🔎 Suggested fix

Add to the imports at the top of the file:

 from typing import Any
+import json

 from supabase import Client

Then update _row_to_model:

     def _row_to_model(self, row: dict[str, Any]) -> CodeExample:
         """Convert a database row to a CodeExample model."""
         metadata = row.get("metadata", {})
         if isinstance(metadata, str):
-            import json
             metadata = json.loads(metadata)

169-259: Extract duplicate embedding column selection logic to a helper method.

The embedding column determination logic (lines 172-183 and 221-232) is duplicated. This violates DRY and makes adding new embedding dimensions error-prone.

🔎 Suggested refactor
+    def _get_embedding_column(self, dimension: int | None) -> str | None:
+        """Get the embedding column name for a given dimension."""
+        if dimension == 768:

299-313: Optimize count query by selecting minimal columns.

select("*", count="exact") fetches all columns when only the count is needed. Select a single column (like id) for better performance.

🔎 Suggested fix

54-68: Singleton reset may leave stale state on existing references.

Container.reset() clears _instance but doesn't reset _init_done on existing objects. If any code holds a reference to the old container, creating a new Container() returns a fresh instance, but the old reference remains in a partially valid state.

For test isolation, also resetting instance attributes in reset() would be safer:

🔎 Suggested fix
     @classmethod
     def reset(cls) -> None:
         """

         cls._instance = None
         logger.info("Container singleton reset")

113-115: Preserve full stack trace in error logging.

Per coding guidelines, error logging should use exc_info=True to preserve the full stack trace.

🔎 Suggested fix
         except Exception as e:
-            logger.error(f"Container initialization failed: {e}")

             raise
python/src/server/infrastructure/memory/code_examples_repository.py (2)

180-186: insert_batch is not atomic - each insert acquires lock separately.

insert_batch calls self.insert() in a loop, acquiring and releasing the lock for each item. This differs from the behavior of Supabase and PostgreSQL implementations which perform batch operations atomically. For test fidelity, consider making this atomic:

🔎 Suggested fix
     async def insert_batch(self, examples: list[CodeExampleCreate]) -> list[CodeExample]:
         """Insert multiple code examples in a batch."""
-        results = []
-        for example in examples:
-            created = await self.insert(example)
-            results.append(created)
-        return results
+        with self._lock:
+            results = []
+            for example in examples:
+                example_id = str(uuid.uuid4())
+                now = datetime.now(timezone.utc)
+                # ... (inline the insert logic here)
+                # Or refactor to have _insert_unlocked helper
+            return results

Alternatively, create an _insert_unlocked helper that both insert and insert_batch can use.


243-247: set_example silently ignores examples without an ID.

If example.id is None, the method does nothing without feedback. Consider raising a ValueError or auto-generating an ID to avoid silent failures in test setup.

🔎 Suggested fix
     def set_example(self, example: CodeExample) -> None:
         """Directly set an example (for test setup)."""

python/src/server/infrastructure/postgres/crawled_pages_repository.py (3)

340-345: Fragile parsing of DELETE result status.

Parsing result.split()[-1] assumes PostgreSQL always returns "DELETE N" format. While this is the documented behavior, adding error handling makes the code more robust:

🔎 Suggested fix
-                # Parse "DELETE X" to get count
-                deleted_count = int(result.split()[-1])
+                # Parse "DELETE X" to get count
+                try:
+                    deleted_count = int(result.split()[-1])
+                except (IndexError, ValueError):
+                    self._logger.warning(f"Could not parse delete result: {result}")
+                    deleted_count = 0

90-92: Add exc_info=True to all error logging calls.

Per coding guidelines, error logging should preserve full stack traces. This pattern should be applied to all error handlers in this file (lines 91, 110, 129, 207, 264, 329, 348, 367, 386, 410).

🔎 Example fix
         except Exception as e:
-            self._logger.error(f"get_by_id failed: {e}", id=id)
+            self._logger.error(f"get_by_id failed: {e}", id=id, exc_info=True)
             raise

267-330: Batch insert correctly uses transactions but has duplicate column-building logic.

The transaction usage ensures atomicity (good). However, the embedding column determination and query building (lines 278-318) duplicates the logic in insert(). Consider extracting a helper method to reduce duplication.

python/src/server/infrastructure/postgres/code_examples_repository.py (2)

342-347: Same fragile DELETE result parsing as crawled_pages repository.

Apply the same defensive parsing pattern suggested for PostgresCrawledPagesRepository.delete_by_url.


90-92: Add exc_info=True to error logging calls throughout this file.

Same pattern as PostgresCrawledPagesRepository - all error handlers should preserve stack traces per coding guidelines.

python/tests/unit/repositories/test_repository_contract.py (2)

25-37: Contract classes import ABC but don't inherit from it.

ABC is imported (line 10) but the contract classes don't inherit from it. While this works (Python doesn't enforce abstract fixture implementations), inheriting from ABC would make the intent clearer:

🔎 Suggested fix
-class CrawledPagesRepositoryContract:
+class CrawledPagesRepositoryContract(ABC):
     """
     Contract tests for ICrawledPagesRepository implementations.

Apply similarly to SourcesRepositoryContract and CodeExamplesRepositoryContract.


163-222: Consider adding contract tests for search_similar and batch operations.

The contract tests cover basic CRUD but omit search_similar (a core feature for vector search) and batch insert operations. Adding these would ensure consistent behavior across all backends:

🔎 Example test for search_similar
@pytest.mark.asyncio
async def test_search_similar_returns_results(self, repo):
    """search_similar should find semantically similar examples."""
    embedding = [0.1] * 768  # Example embedding
    example = CodeExampleCreate(
        source_id="test_source",
        page_url="https://test.com/page",
        code="print('hello')",
        language="python",
        embedding=embedding,
        embedding_dimension=768,
    )
    await repo.insert(example)
    
    results = await repo.search_similar(embedding, match_count=5)
    
    assert len(results) >= 1
    assert results[0].similarity > 0.5
python/tests/unit/test_container.py (1)

66-94: Consider adding test for initialization failure handling.

The tests verify successful initialization and idempotent calls, but don't test error handling when initialization fails (e.g., invalid configuration). A test with a mock that raises during repository access would validate the error propagation.

Empty password default may cause confusing connection failures.

SQL injection risk with f-string table name interpolation.

The table_name parameter is interpolated directly into SQL queries (e.g., line 81, 100, 119, etc.). While the default is safe, if a caller passes untrusted input, this becomes an injection vector.

Consider validating the table name format or using an allow-list:

Synchronous getters lack thread-safety despite async-only usage pattern.

The lazy initialization pattern in get_crawled_pages_repository(), get_sources_repository(), and get_code_examples_repository() is not thread-safe. While the current architecture mitigates this risk—FastAPI's lifespan initializes repositories sequentially before accepting requests—adding a lock would prevent potential issues if these functions are ever called from actual threads. Note that the memory-based repositories already implement threading.Lock for thread-safety internally, suggesting this pattern is valued in the codebase.

guard the check-and-create sequence (acquire the lock, re-check if the global is
None, create and assign the repository, then release via a context manager) so
initialization becomes thread-safe without changing the existing initialization
logic or semantics.

Container initialization failure should crash when explicitly configured.

Per coding guidelines, database connection failures should "crash with clear errors." Currently, if REPOSITORY_TYPE=postgres is set but the PostgreSQL pool fails to initialize, the app continues with only a warning. This could lead to silent failures where health checks pass but all repository operations fail.

Consider re-raising the exception when a non-default backend is explicitly configured:

container.initialize() currently only logs a warning on exception; change this
so that when a non-default backend is explicitly configured (e.g.
REPOSITORY_TYPE == "postgres" or container.storage_type == "postgres") the
exception is not swallowed: log the error with full exception details and then
re-raise the exception (or call sys.exit(1)) so the process crashes with a clear

137-144: filter_metadata is silently ignored when source_id is provided.

This issue was already flagged in a previous review. When source_id is set, line 140 assigns an empty dict to rpc_params["filter"], discarding any filter_metadata the caller provided.

35-38: SQL injection risk with table_name parameter.

This issue was already flagged in a previous review. The table_name parameter is interpolated directly into SQL queries throughout the file, creating a potential SQL injection vector if untrusted input is passed.

python/src/server/infrastructure/postgres/crawled_pages_repository.py-364-364 (1)

364-364: Add defensive parsing for DELETE result.

Line 364 in delete_by_source() parses the DELETE result without error handling, while delete_by_url() (lines 342-346) uses a try/except block with a fallback. This inconsistency could cause delete_by_source() to fail if the result format is unexpected.

🔎 Proposed fix

🧹 Nitpick comments (4)
python/src/server/infrastructure/supabase/code_examples_repository.py (1)

173-183: Consider extracting duplicate embedding column logic.

The embedding column determination logic is duplicated between insert and insert_batch. Consider extracting to a helper method for maintainability.

🔎 Proposed refactor

Add a helper method to the class:

def _get_embedding_column(self, dimension: int | None) -> str | None:
    """Determine the embedding column name based on dimension."""
    if dimension is None:
        return None
    return {
    }.get(dimension)

Then simplify both methods:

-            # Determine embedding column
-            embedding_column = None
-            if example.embedding and example.embedding_dimension:
-                dim = example.embedding_dimension
-                if dim == 768:
-                    embedding_column = "embedding_768"
-                elif dim == 1024:
-                    embedding_column = "embedding_1024"
-                elif dim == 1536:
-                    embedding_column = "embedding_1536"
-                elif dim == 3072:
-                    embedding_column = "embedding_3072"
+            embedding_column = self._get_embedding_column(example.embedding_dimension)

Also applies to: 220-232

python/src/server/infrastructure/supabase/crawled_pages_repository.py (2)

42-44: Consider moving json import to the top of the file.

While inline imports are functionally safe, moving the json import to the module-level imports (line 7) would be more conventional and slightly more efficient if this method is called frequently.

🔎 Proposed refactor

At the top of the file:

 from typing import Any
+import json
 
 from supabase import Client

In the method:

         metadata = row.get("metadata", {})
         if isinstance(metadata, str):
-            import json
             metadata = json.loads(metadata)

222-234: Extract duplicated embedding column determination logic.

The embedding column determination logic (lines 173-185 in insert() and 222-234 in insert_batch()) is identical. Consider extracting this to a helper method to improve maintainability.

🔎 Proposed refactor
+    def _get_embedding_column(self, dimension: int | None) -> str | None:
+        """Determine embedding column name from dimension."""
+        if not dimension:
+            return None
+        
+        if dimension == 768:
+            return "embedding_768"
+        elif dimension == 1024:
+            return "embedding_1024"
+        elif dimension == 1536:
+            return "embedding_1536"
+        elif dimension == 3072:
+            return "embedding_3072"
+        return None
+
     async def insert(self, page: CrawledPageCreate) -> CrawledPage:
         """Insert a new crawled page chunk."""
         try:
             # Determine embedding column
-            embedding_column = None
-            if page.embedding and page.embedding_dimension:
-                dim = page.embedding_dimension
-                if dim == 768:
-                    embedding_column = "embedding_768"
-                elif dim == 1024:
-                    embedding_column = "embedding_1024"
-                elif dim == 1536:
-                    embedding_column = "embedding_1536"
-                elif dim == 3072:
-                    embedding_column = "embedding_3072"
+            embedding_column = self._get_embedding_column(page.embedding_dimension) if page.embedding else None

Apply the same pattern in insert_batch().

38-40: Consider moving json import to the top of the file.

Same suggestion as in crawled_pages_repository.py—moving the json import to module-level would be more conventional.

1-21: LGTM!

Module structure, imports, and similarity threshold constant are appropriate.


22-38: LGTM!

Class initialization and logger binding follow best practices.

python/src/server/infrastructure/memory/sources_repository.py (1)

1-176: LGTM! Well-structured in-memory repository implementation.

The implementation demonstrates solid practices:

  • Thread-safe operations with proper lock usage
  • Timezone-aware datetime handling
  • Immutable updates through model reconstruction
  • Clean test helper methods for test setup/teardown
python/src/server/infrastructure/supabase/sources_repository.py (1)

158-162: Excellent defensive copy to prevent mutation.

The explicit copy ({**updates, ...}) with a clear comment demonstrates good defensive programming and prevents unintended side effects on the caller's dictionary.

python/src/server/infrastructure/postgres/crawled_pages_repository.py (2)

47-56: LGTM! Robust embedding parsing.

The parse_embedding helper handles multiple formats (string JSON, iterables, None) defensively, which is appropriate for the different ways pgvector might return embedding data.


207-207: Good! Error logging includes exc_info=True.

This is the correct pattern per coding guidelines. However, note that this is inconsistent with other error logging in the file (lines 91, 110, 129, 264, 329, 352, 370, 390, 414) which are missing exc_info=True.

python/tests/conftest.py (3)

197-221: LGTM! Clean repository fixtures with proper cleanup.

The memory repository fixtures follow pytest best practices:

  • Clear initialization
  • Yield for test usage
  • Cleanup with clear() to ensure test isolation

224-247: LGTM! Proper environment variable isolation.

The fixture correctly:

  • Stores the original REPOSITORY_TYPE value
  • Sets it to "memory" for the test
  • Restores the original value (or removes if not set)
  • Resets repository singletons before and after

This ensures clean test isolation.


250-278: LGTM! Proper container lifecycle management for tests.

The fixture provides excellent test isolation by:

  • Resetting the Container singleton
  • Setting memory repository type
  • Resetting repository singletons
  • Importing the container after environment setup
  • Cleaning up all state after the test

This ensures each test using this fixture gets a fresh, isolated container.

python/src/server/container.py (1)

82-146: LGTM! Well-structured lifecycle management.

The initialization and shutdown methods follow best practices:

  • Idempotent operations with proper state guards
  • Early validation through eager repository pre-warming (lines 106-108)
  • Full stack traces preserved with exc_info=True (lines 114, 145)
  • Fail-fast behavior for startup failures
python/src/server/infrastructure/postgres/sources_repository.py (2)

269-295: Good defensive parsing for DELETE results.

The defensive parsing (lines 279-284) properly handles edge cases where the asyncpg DELETE result format might vary, with appropriate fallback behavior and warning logs.


36-53: LGTM! Robust type handling.

The _row_to_model() method correctly handles metadata as both dict and string (lines 39-40), which provides resilience against schema variations.

⚠️ Potential issue | 🟠 Major

Add exc_info=True to all error logs for complete stack traces.

Most error logs are missing exc_info=True, which violates the coding guidelines requirement to "preserve full stack traces with exc_info=True in Python logging." Only list_all() (line 102) and count() (line 308) include it.

Missing in:

162 to 201, the update() method currently mutates the caller-supplied updates
dict by setting updates["updated_at"]; to fix, create a new local dict (shallow
copy) from the incoming updates and add the updated_at key to that copy, then
use the copy for serialization and query construction (do not modify the
original updates), and ensure any metadata dict is JSON-serialized from the copy
as before.

137-144: filter_metadata is silently ignored when source_id is provided.

When source_id is set, filter is assigned an empty dict, discarding any filter_metadata the caller provided. Callers might expect both filters to apply.

39-62: Add error handling for metadata JSON parsing.

If metadata is a malformed JSON string, json.loads() will raise a JSONDecodeError without context about which row failed. Per coding guidelines, this should either fail fast with context or skip corrupted data.

144-154: Post-query language filtering may return fewer results than match_count.

When language is specified, filtering happens after fetching match_count rows (lines 151-152). If several rows don't match the language, fewer than match_count results are returned. Consider documenting this limitation or updating the RPC to support language filtering server-side for consistent behavior across backends.

247-260: Fix count query to use correct column selection pattern.

The count() method uses .select("id", count="exact"), but the table uses source_id as its identifier, not id. This will cause the query to fail. Use .select("*", count="exact") to match the pattern used elsewhere in the codebase (e.g., database_metrics_service.py, knowledge_item_service.py).

Learning: Server-side counting optimization pattern: When counting rows by status/category in Supabase, use separate queries with count="exact" parameter instead of fetching all rows. Example: supabase_client.table("table").select("id", count="exact").eq("field", "value").execute() and read res.count.

⚠️ Potential issue | 🟠 Major

Add error handling for metadata JSON parsing.

If metadata is a malformed JSON string, json.loads() will raise a JSONDecodeError without context. Per coding guidelines, this should fail fast with context or skip corrupted data.

35 to 53, the code calls json.loads(metadata) without handling malformed JSON;
wrap the json.loads call in a try/except that catches json.JSONDecodeError and
raise a new ValueError (or a custom exception) that includes the source_id
(row.get("source_id")), the original error message, and the raw metadata string
(use "from e" to preserve traceback) so the function fails fast with context for
debugging.

Supabase PostgREST client SQL injection protection escaping parameters

💡 Result:

Short answer

  • The Supabase REST client (PostgREST) does not let you inject raw SQL through its HTTP endpoints; PostgREST escapes literal values when building queries and you should avoid constructing dynamic SQL on the server/client side. [1][2]

Recommended protections

  • Use the REST/JS client or RPC (stored procedures) with typed parameters instead of concatenating strings into SQL. RPC parameters are passed as data, not raw SQL. [2]
  • If you must run SQL from a server driver (pg, psycopg, asyncpg, etc.), always use parameterized queries / prepared statements (driver placeholders like $1) rather than string interpolation. [4]
  • For any dynamic SQL generated inside PL/pgSQL, use quote_literal() and quote_ident() (or proper parameterization) and strongly validate/whitelist identifiers. [3]
  • Avoid building SQL with user-controlled identifiers; if you must accept names (table/column), whitelist or use quote_identifier helpers from libraries (or pg_escape). [3][5]

Practical checklist

  • Don’t send raw SQL over HTTP to PostgREST — use filters, RPC, or policy-based endpoints. [2]
  • Use client/driver parameter placeholders ($1, $2) on server-side DB connections. [4]
  • Validate and whitelist any user-supplied identifier names. [3][5]
  • If you audit PostgREST behavior: the project escapes literals internally, but you shouldn’t rely on client-side escaping—design for parameterization. [1]

If you want, tell me which language/driver or whether you’re using the JS Supabase client vs a server DB driver and I’ll give concrete code examples.

🌐 Web query:

PostgreSQL LIKE operator escape percent underscore Supabase

💡 Result:

Short answer

  • In PostgreSQL LIKE patterns, % and _ are wildcards. Precede them with an escape character to match them literally (default escape is backslash). Use ESCAPE to choose a different escape char. [1]

Examples

  • SQL literal (escape % with backslash): SELECT * FROM t WHERE col LIKE '%100%%'; -- matches strings that end with "100%". In SQL string literals you may need to double backslashes depending on string-escape settings, e.g. '%100\%%'. [1][2]
  • Use a custom escape char: SELECT * FROM t WHERE col LIKE '%50!%%' ESCAPE '!'; -- here ! escapes %. [1]
  • To match a literal underscore: WHERE col LIKE 'file_name' (or 'file\_name' in some string contexts). [1][2]

Supabase / client notes

  • Supabase uses Postgres (PostgREST), so the same escaping rules apply. When sending patterns from a client:
    • Use parameterized queries or the client library methods (e.g., .rpc / SQL or filter/ilike) so you avoid manual quoting issues.
    • If you build the pattern as a string, escape backslashes for the client language (e.g. in JS string literals use '\%') and URL-encode the pattern when calling the REST endpoint. [1]

Sources

  • PostgreSQL pattern matching / LIKE (escape and ESCAPE clause). [1]
  • Example usage and notes on backslash escaping in string literals. [2]

Escape LIKE wildcard characters (% and _) in the search query.

The query parameter is directly interpolated into the ILIKE pattern without escaping PostgreSQL's wildcard metacharacters. In PostgreSQL, % matches any characters and _ matches a single character. User input like "50%" will be interpreted as a wildcard pattern matching "50anything" rather than the literal string "50%".

To fix, escape backslashes in the search term before interpolation:

escaped_query = query.replace("\\", "\\\\").replace("%", "\\%").replace("_", "\\_")
response = (
    self.client.table(self.table_name)
    .select("*")
    .or_(f"title.ilike.%{escaped_query}%,description.ilike.%{escaped_query}%")
    .order("created_at", desc=True)
    .execute()
)

This same pattern appears in knowledge_summary_service.py, knowledge_item_service.py, and task_service.py—apply the same fix across all search methods.

109-125, the search method interpolates the raw query into the ILIKE pattern
allowing PostgreSQL wildcards (%) and (_) to change semantics; escape
backslashes, percent signs and underscores in the input before building the
ILIKE pattern (e.g. replace "\" with "\\", then "%" with "\%", then "_" with
"\_"), use the escaped string in the .or_() interpolation, and keep using ILIKE
for case-insensitive search; apply the identical escaping fix to the search
implementations in knowledge_summary_service.py, knowledge_item_service.py, and
task_service.py.

117-133: LIKE wildcard escaping still missing (duplicate issue).

174-215: Consider extracting embedding column selection logic.

The embedding column selection pattern (lines 178-188) is duplicated in both insert and insert_batch methods, and similar logic appears across all three repository files. Consider extracting this into a private helper method to reduce duplication and improve maintainability.
