Fix Test Mock Configuration and Improve URL Validation API

Summary

This PR addresses code review feedback from PR #847 by fixing async mock configurations in integration tests and improving the URL validation module's maintainability.

Changes

1. Fixed Async Mock Configuration (Test Suite)

Files Changed:

python/tests/server/api_routes/test_preview_links_integration.py

Issues Fixed:

Lines 317-323, 442-449, 475-482: Mock objects were using AsyncMock incorrectly, missing proper async context manager protocol support
Lines 165, 170, 206, 211, 249, 254: __aexit__ configurations were inconsistent

Solution:

# Before (incorrect)
mock_response = AsyncMock()
mock_response.status = 200
mock_response.text = AsyncMock(return_value=SAMPLE_LLMS_TXT)
mock_session_instance = AsyncMock()
mock_session_instance.get = AsyncMock(return_value=mock_response)

# After (correct)
mock_response = MagicMock()
mock_response.status = 200
mock_response.text = AsyncMock(return_value=SAMPLE_LLMS_TXT)
mock_response.__aenter__ = AsyncMock(return_value=mock_response)
mock_response.__aexit__ = AsyncMock(return_value=None)

mock_session_instance = MagicMock()
mock_session_instance.get.return_value = mock_response
mock_session_instance.__aenter__ = AsyncMock(return_value=mock_session_instance)
mock_session_instance.__aexit__ = AsyncMock(return_value=None)

Impact:

Ensures mocks properly support async with session.get(...) as response: pattern
Standardizes all mock configurations across test suite
Prevents potential test failures when endpoint uses async context managers

2. Extracted Magic Numbers to Constants

File Changed:

python/src/server/utils/url_validation.py

Improvement:

# Added module-level constants for better maintainability
MAX_GLOB_PATTERNS = 50
MAX_PATTERN_LENGTH = 200

# Updated function to use constants
if len(patterns) > MAX_GLOB_PATTERNS:
    raise HTTPException(
        status_code=400,
        detail=f"Too many patterns. Maximum {MAX_GLOB_PATTERNS} allowed."
    )

if len(pattern) > MAX_PATTERN_LENGTH:
    raise HTTPException(
        status_code=400,
        detail=f"Pattern too long (max {MAX_PATTERN_LENGTH} characters): {pattern[:50]}..."
    )

Benefits:

Easier to adjust limits in one place
Self-documenting code
Consistent error messages
Follows DRY principle

3. Improved API Naming Consistency

Files Changed:

python/src/server/utils/url_validation.py
python/src/server/api_routes/knowledge_api.py

Changes:

Renamed validate_url_against_ssrf() to validate_url() for cleaner API
Added backward compatibility alias: validate_url_against_ssrf = validate_url
Updated imports to use new function name

Rationale:

Shorter, cleaner function name
SSRF protection is implied in URL validation context
Maintains backward compatibility for existing code

4. Fixed Test Expectations

File Changed:

python/tests/server/api_routes/test_preview_links_integration.py

Fix:

Updated test_llms_full_txt_with_patterns to correctly expect that llms-full.txt is NOT treated as a link collection
Added clarifying comment about intended behavior

Context:
Per the URLHandler implementation, files with "full" in the name (like llms-full.txt) are intentionally NOT treated as link collections to preserve single-page crawl behavior. The test now correctly validates this design decision.

# Verify: llms-full.txt is explicitly NOT treated as a link collection
# It should be crawled as a single page to preserve full-content behavior
assert result["is_link_collection"] is False
assert result["collection_type"] is None
assert "not a link collection" in result["message"].lower()

Testing

All tests passing:

# Integration tests
uv run pytest tests/server/api_routes/test_preview_links_integration.py -v
# ✅ 11/11 tests passing

# URL validation tests
uv run pytest tests/server/utils/test_url_validation.py -v
# ✅ 34/34 tests passing

Test Coverage:

✅ Async context manager protocol support
✅ SSRF protection (localhost, private IPs, invalid protocols)
✅ Glob pattern sanitization (command injection, path traversal, length limits)
✅ Link collection detection (llms.txt, sitemap.xml)
✅ Edge cases (empty files, non-link collections)

Validation Results

Security validation now works correctly:

# SSRF protection - returns 400 for localhost
request = LinkPreviewRequest(url="http://localhost:8080/llms.txt", ...)
# HTTPException: status_code=400, detail="Access to localhost is not allowed"

# Pattern sanitization - returns 400 for command injection
request = LinkPreviewRequest(
    url="https://docs.example.com/llms.txt",
    url_include_patterns=["david"],
    ...
)
# HTTPException: status_code=400, detail="Invalid characters in pattern: david"

Breaking Changes

None. The validate_url_against_ssrf function is still available as an alias.

Checklist

All tests passing (45/45)
Code follows project style guidelines
No breaking changes introduced
Security validations working correctly

Summary by CodeRabbit

New Features
- Added GitHub repository auto-configuration with pre-populated URL patterns and depth settings
- Introduced link review workflow to preview and select specific links before crawling (supports llms.txt, sitemap.xml)
- Added glob pattern filtering support for precise URL inclusion/exclusion during crawl operations
Documentation
- Added comprehensive testing strategy guide and glob pattern filtering reference
Bug Fixes
- Improved dialog content area layout for better height responsiveness

Implements interactive link review and URL filtering for llms.txt and sitemap.xml crawling: Backend changes: - Add glob pattern matching utility (url_handler.py) - Create preview endpoint POST /api/crawl/preview-links for link collection analysis - Update crawl request models to support url_include_patterns, url_exclude_patterns, selected_urls, skip_link_review - Integrate pattern filtering into crawling logic with selected_urls support - Use aiohttp for fast link collection fetching (replaces slow browser crawling for .txt files) Frontend changes: - Add LinkReviewModal component for interactive link selection before crawling - Update AddKnowledgeDialog with pattern filter inputs and "Review links" checkbox - Add preview flow: detects link collections → shows modal → user selects links → crawls only selected - Fix dialog.tsx wrapper to support full-height flex layouts (h-full class) - Replace invalid <p> nesting with <div> elements for HTML standards compliance Features: - Glob pattern filtering (e.g., **/en/** to include only English pages) - Interactive link preview modal with bulk select/deselect, search, and individual selection - Auto-selection based on filter patterns with "Matches Filter" badges - Scrollable link list supporting 2000+ links - Apply Filters button to refine selection in real-time Fixes scroll issues by ensuring proper flex layout height propagation in dialog components.

…Hub auto-config This commit extends the glob pattern filtering feature (from commit 74023e1) to support recursive crawls and improves GitHub repository handling. ## Changes ### Backend - Recursive Crawl Filtering - Add include_patterns and exclude_patterns parameters to RecursiveCrawlStrategy - Filter internal links during discovery (before adding to crawl queue) - Pass patterns through entire call chain (orchestration → service → strategy) - Add comprehensive logging for pattern configuration and filtered URLs - Performance: Prevents unnecessary HTTP requests and memory usage Files: - python/src/server/services/crawling/strategies/recursive.py: * Lines 45-46: Add pattern parameters to function signature * Lines 59-60: Update docstring * Lines 173-178: Log pattern configuration at crawl start * Lines 316-339: Implement filtering logic during link discovery - python/src/server/services/crawling/crawling_service.py: * Lines 271-272: Add parameters to wrapper method * Lines 283-284: Pass patterns to recursive strategy * Lines 349-356: Add early logging for crawl parameters * Lines 1145-1153: Extract and pass patterns from request ### Frontend - Improved GitHub Auto-Configuration - Change GitHub auto-config from path-based to code-only patterns - Use **/tree/**, **/blob/** instead of /username/repo* - Automatically excludes issues, PRs, actions, wiki, etc. - More efficient and future-proof than exclusion lists Files: - archon-ui-main/src/features/knowledge/components/AddKnowledgeDialog.tsx: * Lines 73-75: Updated pattern generation logic ### Documentation - Add comprehensive glob pattern guide with examples - Document GitHub auto-configuration rationale - Include pattern syntax, use cases, and testing tips Files: - docs/GLOB_PATTERNS.md: New file (253 lines) ## Benefits 1. **Memory Efficiency**: Prevents memory errors on large GitHub repositories 2. **Performance**: Filters URLs before crawling (saves HTTP requests) 3. **Storage**: Reduces database writes (fewer pages to store) 4. **User Experience**: GitHub repos now auto-configured optimally ## Testing - Unit tests: All passing (19/19 glob pattern tests) - Frontend tests: All passing (29/29 LinkReviewModal tests) - Integration tests: Pre-existing failures unrelated to this feature - Manual testing: GitHub crawl with code-only patterns verified ## Pattern Examples Documentation sites (language filtering): **/en/**, !**/api/**, !**/changelog/** GitHub repositories (code only): **/tree/**, **/blob/** Blog sites: **/blog/**, !**/draft/** ## Related - Builds on commit 74023e1 (glob pattern filtering for link collections) - Resolves memory issues with GitHub repository crawling - Implements recursive crawl filtering requested in design discussions

Changes LinkReviewModal props from a single unified pattern string to separate initialIncludePatterns and initialExcludePatterns arrays for better type safety and clearer intent. - LinkReviewModal: Accept array props, reconstruct unified string internally - AddKnowledgeDialog: Parse comma-separated patterns into arrays before passing - Tests: Updated to use new array-based interface All 29 tests passing.

Extract duplicated parseUrlPatterns function from AddKnowledgeDialog and LinkReviewModal into a shared utility module to reduce code duplication and improve maintainability.

Address three issues identified in code review: 1. LinkReviewModal: Fix search to preserve pattern filters - Add baseLinks state to persist pattern-filtered results - Update search effect to filter from baseLinks (fallback to previewData.links) - Modify handleApplyFilters to update baseLinks before setFilteredLinks - Searches now correctly apply to currently filtered set 2. url_validation: Fix IPv6 SSRF bypass vulnerability - Replace IPv4-only socket.gethostbyname with comprehensive check - Parse numeric IPs first with ipaddress.ip_address (handles IPv4/IPv6) - Use socket.getaddrinfo for hostname resolution (both IPv4/IPv6) - Validate all resolved addresses for private/loopback/link-local - Proper exception handling for socket.gaierror and ValueError 3. Tests: Fix aiohttp mock async context manager - Change from AsyncMock() to MagicMock() for objects - Configure __aenter__ and __aexit__ as AsyncMock - Use .return_value property instead of AsyncMock(return_value=...) - Ensures "async with session.get(...)" works correctly All 11 integration tests passing.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~60 minutes

Areas requiring close attention:

Backend URL pattern matching logic (url_handler.py, recursive.py): Glob pattern semantics, fnmatch correctness, and filtering precedence (exclude-first, then include) should be validated against real-world URLs and edge cases.
SSRF protection implementation (url_validation.py): DNS resolution handling, private IP detection, and protocol validation require careful security review; check for bypasses via IPv6, numeric representations, or resolution edge cases.
Link preview endpoint (knowledge_api.py): URL validation, sanitization, and collection type detection (llms.txt vs sitemap.xml vs non-collection) logic; ensure safe handling of external content.
Frontend link review workflow (AddKnowledgeDialog.tsx, LinkReviewModal.tsx): State management during preview/filtering/selection phases; modal cancel/confirm flows and edge cases (empty selections, API errors, filter re-application).
Test coverage depth: Comprehensive test suites are provided; verify integration test mocking accuracy and realistic crawl scenarios.
