Pull request overview
This PR implements comprehensive network configuration and proxy detection for Cortex Linux, enabling the package manager to work seamlessly in corporate networks with proxies, behind VPNs, and in offline environments. The implementation auto-detects proxy settings from multiple sources (environment variables, GNOME settings, system files), handles VPN connections, supports proxy authentication, and provides graceful offline fallback with package caching.
Key Changes:
- Automatic proxy detection from environment variables, GNOME settings, and system configuration files
- VPN detection support for OpenVPN, WireGuard, and IPSec
- Network connectivity and quality testing with multiple fallback mechanisms
- Automatic configuration of apt and pip to use detected proxies
- Offline mode with JSON-based package caching

204-246: LGTM!VPN detection tests cover the key scenarios: tun interface, WireGuard, no VPN present, and graceful handling when the
ipcommand is unavailable.
248-312: LGTM!Connectivity tests properly cover DNS resolution success, HTTP fallback when DNS fails, and network quality detection with time mocking.
314-417: LGTM!Configuration tests comprehensively cover apt proxy setup (success, no proxy, permission denied), pip proxy environment variable setup, httpx proxy config generation for HTTP/HTTPS/SOCKS, and cleanup scenarios.
419-513: LGTM!Package caching tests thoroughly cover cache creation, IO error handling, successful retrieval, cache expiration, missing files, invalid JSON parsing, and offline fallback scenarios.
515-660: LGTM!The remaining test classes provide solid coverage:
TestAutoConfigurevalidates offline mode, proxy configuration, and VPN detection flowsTestHelperFunctionscovers proxy auth checking, credential prompting, and URL constructionTestPrintSummaryensures summary output doesn't raise exceptionsTestIntegrationvalidates full detection and offline mode flowsThe test suite provides comprehensive coverage of the NetworkConfig module.
cortex/network_config.py (6)
39-62: LGTM!The initialization properly supports lazy loading via
auto_detectparameter, and thedetect()method has idempotency protection with the_detectedflag.
86-208: LGTM!Proxy detection implementation is well-structured with clear priority order (environment → GNOME → system files), proper error handling, and support for HTTP/HTTPS/SOCKS proxies.
298-368: LGTM!Configuration methods properly:
- Use separate HTTP/HTTPS proxy URLs with fallback
- Handle sudo for apt configuration
- Support SOCKS proxies in httpx config
371-438: LGTM!Package caching implementation properly handles:
- Writing cache with timestamp
- Reading with age validation
- Graceful degradation on IO errors
- User-friendly offline fallback messages
440-521: LGTM!The cleanup, auto-configuration, and summary methods are well-implemented:
cleanup_apt_proxysafely removes the config fileauto_configureproperly orchestrates offline mode, proxy configuration, and VPN detectionprint_summaryprovides clear, formatted output
567-594: LGTM!The
add_proxy_authfunction properly:
- URL-encodes credentials to handle special characters (
@,:,/,%)- Documents the security implications in the docstring
- Logs a warning about credential embedding
- Handles both protocol-prefixed and bare URLs

38-64: Consider defaulting auto_detect to False for faster CLI startup.While the
auto_detectparameter addresses the slow initialization concern from past reviews, it defaults toTrue, meaning detection still runs during construction by default. For CLI tools where fast startup matters, consider defaulting toFalseand having callers explicitly trigger detection via.detect()when needed, or document that initialization may be slow.
352-372: Consider more specific return type hint.The return type

259-268: LGTM - Socket timeout properly scoped.The socket timeout is correctly applied to the individual socket instance rather than globally, avoiding the issue raised in past reviews.
303-350: LGTM - Proxy configuration correctly handles HTTP and HTTPS separately.Both
configure_apt_proxyandconfigure_pip_proxynow properly respect separate HTTP and HTTPS proxy values with appropriate fallback, addressing concerns from past reviews.
573-600: LGTM - Credentials properly URL-encoded with security warnings.The function now correctly URL-encodes credentials to handle special characters, and includes appropriate security warnings about credential exposure. This addresses concerns from past reviews.
231-243: LGTM - Exception handling with clear comments.The empty except clauses include explanatory comments about why failures are silently ignored during detection, which is appropriate for this probing code.
577-600: Security warnings appropriately documented.The function includes comprehensive security warnings about credential exposure in both the docstring and logging, which is essential for this sensitive operation.
376-428: LGTM - Offline caching implementation is sound.The package caching implementation includes proper age validation, error handling, and logging. The 24-hour default cache age is reasonable for package lists.
464-503: LGTM - Comprehensive auto-configuration with clear user feedback.The auto-configuration orchestration handles offline mode, connectivity issues, proxy setup, and VPN detection gracefully with informative console messages.

1-607: Implementation looks solid after past review fixes.The
cortex/network_config.pyimplementation has addressed all previously flagged issues:
- Socket timeout now uses instance-level
settimeout()instead of global timeout- Credentials are properly URL-encoded using
quote()- Separate handling of HTTP and HTTPS proxies in apt and pip configuration
- Proper error handling with OSError (IOError redundancy removed)
- Module-level imports for all dependencies

1-24: LGTM - Imports and module setup are clean.All imports are properly organized and used throughout the module. The module-level import of
getpass(line 8) andurllib.parse.quote(line 16) correctly address previous review concerns.
38-66: Good design - lazy loading option addresses initialization concerns.The
auto_detectparameter (line 39) allows callers to defer expensive network detection until needed, addressing previous concerns about slow initialization. The_detectedflag (line 56) prevents redundant detection calls. This is a solid pattern for CLI tools where startup time matters.
261-270: Excellent fix - socket timeout is now instance-scoped.The connectivity check now uses
sock.settimeout(timeout)(line 264) on the socket instance rather than modifying global state. This correctly addresses the previous review concern aboutsocket.setdefaulttimeout()affecting other parts of the application.
305-356: Proxy configuration correctly handles separate HTTP/HTTPS proxies.Both
configure_apt_proxy()(line 318) andconfigure_pip_proxy()(line 349) now useself.proxy.get("https", http_proxy)to properly respect distinct HTTPS proxy settings when available, while falling back to the HTTP proxy. This addresses previous review feedback about supporting different proxies for different protocols.
580-607: Well-implemented - credentials are now properly URL-encoded.The function now uses
quote(username, safe="")andquote(password, safe="")(lines 597-598) to properly handle special characters like@,:,/, and%in proxy credentials. The security warning (lines 584-586, 600) appropriately alerts users about credential visibility risks. This correctly addresses the previous major security concern.
538-564: LGTM - proxy authentication check is correctly implemented.The exception handling properly catches
requests.exceptions.ProxyErrorfor 407 status (lines 557-559) and falls back to a generic failure for other request exceptions (line 560). The code does not redundantly catch bothTimeoutandRequestExceptionas mentioned in older comments.
1-607: Comprehensive implementation with excellent improvements from prior reviews.This module successfully addresses all previously identified critical and major issues:
- ✅ Socket timeout now instance-scoped (line 264)
- ✅ URL encoding for proxy credentials (lines 597-598)
- ✅ Separate HTTP/HTTPS proxy support (lines 318, 349)
- ✅ Lazy loading via
auto_detectparameter (line 39)- ✅ Proper error handling throughout
The code follows PEP 8, includes comprehensive docstrings, and provides strong type hints for public APIs. One minor issue remains regarding explanatory comments in empty except clauses (flagged separately).
docs/NETWORK_CONFIG_TESTS.md (1)
1-228: Excellent test documentation - comprehensive and well-structured.The documentation thoroughly covers all 58 tests, organized by test class with clear descriptions. Mocking strategies, running commands, and coverage goals are well-documented. The static analysis hint about line 25 appears to be a false positive—all fenced code blocks in this file correctly specify their language (bash at lines 164-176, python at lines 213-223).
docs/NETWORK_CONFIG.md (1)
1-473: Outstanding module documentation - thorough and user-friendly.This documentation provides comprehensive coverage of the NetworkConfig module with:
- Clear architecture diagrams (lines 25-58)
- Practical usage examples with proper code formatting
- Complete API reference with parameter tables
- Detailed troubleshooting guidance
- Security warnings for proxy credential handling (line 365)
All code blocks are properly tagged with language specifiers, and the content is well-organized for both quick reference and deep understanding. This will significantly aid users working with corporate proxies and VPNs.

@ShreeJejurikar @Suyashd999 The PR fulfills the requirements of the Issue #25 so its ready to merge after these adding these minor tweaks that will improve the performance of the CLI. Issues Found:
Suggested Improvements1. Lazy Loading in CLI (CRITICAL FIX)Before: network = NetworkConfig() # 2.2 seconds - runs full detection
network.auto_configure()After: network = NetworkConfig(auto_detect=False) # 0.1ms - instant
# Only detect when actually needed
if args.command in ['install', 'update', 'upgrade', 'search', 'doctor']:
network.detect()
network.auto_configure()Performance improvement:
2. Optional Network Quality CheckBefore: def detect(self):
# Always checks quality (1-5s delay)
if self.is_online:
self.connection_quality = self.detect_network_quality()After: def detect(self, check_quality: bool = False):
# Only check quality if explicitly requested
if self.is_online and check_quality:
self.connection_quality = self.detect_network_quality()Performance improvement:

807-828: Network configuration doesn't respect the--offlineflag.The network detection runs before the main argument parser processes
--offline. When a user runscortex install nginx --offline, the network detection still occurs. Consider checking for--offlinein the preliminary parse or deferring network config until after full argument parsing.This was previously flagged in an earlier review. The current implementation parses only the command but not global flags like
--offline.🔎 Suggested approach
temp_parser = argparse.ArgumentParser(add_help=False) temp_parser.add_argument('command', nargs='?') + temp_parser.add_argument('--offline', action='store_true') temp_args, _ = temp_parser.parse_known_args() # Commands that need network detection NETWORK_COMMANDS = ['install', 'update', 'upgrade', 'search', 'doctor', 'stack'] - if temp_args.command in NETWORK_COMMANDS: + if temp_args.command in NETWORK_COMMANDS and not temp_args.offline: # Now detect network (only when needed) network.detect(check_quality=True) # Include quality check for these commands network.auto_configure()cortex/network_config.py (1)

🔇 Additional comments (51)
cortex/config_manager.py (3)
12-12: Thread-safe file I/O lock initialization looks good.The
threading.Lock()is correctly initialized in__init__to protect file operations on the preferences file. This aligns with the project-wide thread-safety improvements.Also applies to: 58-58
285-287: Thread-safe file read implementation is correct.The double
withstatement properly acquires the lock before opening the file. This prevents race conditions during concurrent reads.
301-303: Thread-safe file write implementation is correct.The lock acquisition before file write prevents data corruption from concurrent writes to
preferences.yaml.cortex/cli.py (2)
109-175: Notify command implementation looks good.The
notify()method properly handles:
- Missing subcommand with helpful error message
- Time format validation for DND window (lines 152-157)
- Required message validation for send action
Minor note: Lines 136, 142, 161 call
mgr._save_config()which is a private method. Consider adding a publicsave_config()method toNotificationManagerfor better encapsulation, but this is a minor refactor for later.
14-14: NetworkConfig import and help table update are correct.The import and help table entry for the notify command are properly integrated.
Also applies to: 774-774
cortex/llm_router.py (4)
165-172: Thread-safe statistics tracking initialization looks good.The
_stats_lockis properly initialized to protect shared mutable state (total_cost_usd,request_count,provider_stats).
393-402: Thread-safe_update_statsimplementation is correct.The lock properly guards all mutations to shared statistics state.
404-427: Thread-safeget_statsimplementation is correct.Returning a snapshot within the lock ensures a consistent view of statistics.
808-808: Minor line change is fine.The system prompt string is unchanged in functionality.
cortex/demo.py (1)
17-24: Hardware detection API migration looks correct.The switch from dict-style to attribute access (
hw.cpu.model,hw.memory.total_gb,hw.gpu) aligns with the dataclass-basedHardwareInfostructure inhardware_detection.py.cortex/stack_manager.py (2)
11-11: Thread-safety infrastructure is correctly added.The
threadingimport and_stacks_lockinitialization properly set up thread-safe stack loading.Also applies to: 25-25
27-45: Double-checked locking pattern is correctly implemented.The implementation follows the correct pattern:
- Fast path check without lock (line 30-31)
- Lock acquisition (line 34)
- Double-check inside lock (line 35-36)
- Initialization and return within lock (lines 38-45)
Error handling for
FileNotFoundErrorandJSONDecodeErroris properly contained within the locked section.cortex/kernel_features/accelerator_limits.py (2)
14-15: Connection pooling migration is correctly implemented.The
get_connection_poolis properly initialized with the database path and pool size. The table creation is correctly executed within a pooled connection context.Also applies to: 58-60
62-79: All database operations correctly use pooled connections.The
save,get, andlist_allmethods properly useself._pool.get_connection()context manager, ensuring connections are returned to the pool after use.docs/PYTHON_314_ANALYSIS_SUMMARY.md (1)
1-556: Excellent documentation for Python 3.14 free-threading migration.This comprehensive analysis document provides valuable guidance for the thread-safety improvements across the codebase, including:
- Clear prioritization of fixes by severity
- Concrete code examples for common patterns
- Testing strategies and performance projections
- Risk assessment and mitigation strategies
cortex/transaction_history.py (2)
658-662: Thread-safe singleton infrastructure is correctly set up.Module-level locks and instance holders are properly initialized for the double-checked locking pattern.
665-686: Double-checked locking pattern is correctly implemented for both singletons.Both
get_history()andget_undo_manager()follow the correct pattern:
- Fast path check without lock
- Lock acquisition
- Double-check inside lock
- Lazy initialization
The forward reference return types (
"TransactionHistory","UndoManager") are appropriate since the functions are defined after the classes.cortex/dependency_resolver.py (2)
68-72: Thread-safety implementation looks correct.The two-lock approach properly separates concerns:
_cache_lockfor the dependency cache and_packages_lockfor installed packages. This allows concurrent cache lookups while package list refreshes are in progress.
219-223: Cache read is properly protected.The cache lookup correctly acquires the lock before checking and returning cached values. This prevents race conditions when multiple threads resolve dependencies for the same package.
cortex/progress_indicators.py (3)
123-145: Well-implemented thread-safe spinner pattern.The implementation correctly:
- Protects shared state (
_running,_current_message,_spinner_idx) with a lock- Takes local copies of state inside the lock (lines 139-141) and uses them outside
- Minimizes lock hold time by only protecting state access, not I/O operations
152-174: Correct lock ordering in stop/fail methods.Good pattern: capturing the thread reference under the lock, then calling
join()outside the lock. This prevents potential deadlocks if the animation thread tries to acquire the lock during shutdown.
662-672: Double-checked locking for global singleton is correct.The pattern follows the standard double-checked locking idiom with a fast path (line 668) and a slow path with lock acquisition and re-check (lines 669-671).
docs/PYTHON_314_DEVELOPER_CHECKLIST.md (1)
1-8: Excellent developer reference documentation.This checklist provides practical, actionable guidance for implementing thread-safety fixes. The before/after code examples match the patterns being applied across the codebase.
cortex/network_config.py (3)
38-66: Good implementation of lazy loading for CLI performance.The
auto_detectparameter (defaulting toTrue) allows CLI commands that don't need network detection (like--help,--version) to skip the ~2s detection overhead by passingauto_detect=False. This directly addresses the performance concern raised in PR comments.
267-276: Proper socket timeout handling.Good fix: using
sock.settimeout(timeout)on the individual socket instead ofsocket.setdefaulttimeout()avoids affecting global socket state. This addresses the previous review feedback.
602-613: Credentials are properly URL-encoded.The
add_proxy_authfunction now usesquote(username, safe="")andquote(password, safe="")to properly encode special characters in credentials. This addresses the previous review feedback about malformed URLs.cortex/kernel_features/kv_cache_manager.py (1)
51-60: Connection pooling correctly integrated.The
CacheDatabaseclass now uses a connection pool for all database operations. Schema initialization properly uses the pool's context manager.cortex/graceful_degradation.py (2)
77-102: Proper connection pool initialization and usage.The
ResponseCacheclass correctly:
- Initializes the pool via
get_connection_pool()(line 82)- Uses the pool's context manager for schema creation
- Commits the transaction after table creation
507-521: Thread-safe singleton with correct double-checked locking.The
get_degradation_manager()function correctly implements the double-checked locking pattern:
- Fast path check without lock (line 516)
- Lock acquisition and re-check (lines 517-520)
- Proper global declaration
cortex/notification_manager.py (3)
37-37: Thread-safety lock correctly initialized.The
_history_lockis initialized after loading history, which is safe since__init__runs in a single-threaded context. Subsequent operations properly use the lock.
66-70: Verify: _save_history expects lock to be held by caller.The docstring states "Caller must hold self._history_lock", which is correct since
_log_history(lines 152-154) acquires the lock before calling_save_history. This is a valid internal contract for private methods.
142-154: Thread-safe history logging implementation.The
_log_historymethod correctly:
- Builds the entry outside the lock (lines 144-151)
- Acquires the lock only for the append and save operations (lines 152-154)
This minimizes lock contention while ensuring thread-safety.
cortex/semantic_cache.py (3)
76-77: Correct type annotation for optional pool.The
_pool: SQLiteConnectionPool | None = Nonetype hint correctly indicates the pool may be None before_init_database()completes.
88-133: Connection pool properly initialized and used for schema creation.The pool is obtained via
get_connection_pool()(line 90), which provides a thread-safe singleton pool for the database path. Schema creation correctly uses the pool's context manager and commits the transaction.
229-290: Database operations correctly use pooled connections.The
get_commandsmethod properly:
- Acquires a connection from the pool via context manager
- Performs all database operations within the context
- Commits after updates
- Connection is automatically returned to pool on exit
cortex/installation_history.py (1)
20-21: Good adoption of the connection pool pattern.The import and initialization of the connection pool are correctly implemented with the pool attribute and
get_connection_pool()call. The database schema initialization correctly uses the pool context manager.Also applies to: 79-80, 94-134
cortex/hardware_detection.py (1)
196-196: Thread-safe cache I/O implementation looks good.The
_cache_lockusingthreading.RLock()correctly protects both_load_cacheand_save_cachemethods. Using RLock is appropriate here as it allows the same thread to re-acquire the lock if needed. The guard check forself.use_cachebefore the lock is a good optimization.Also applies to: 252-315
docs/PYTHON_314_COMPLETE_IMPLEMENTATION.md (1)
1-21: Comprehensive documentation for the thread-safety implementation.The executive summary and key achievements provide a clear overview of the work done. The phased approach and detailed test results are helpful for understanding the scope and validation of changes.
tests/test_thread_safety.py (2)
44-63: Test may produce false positives with the current singleton implementation.This test verifies that
get_detector()returns the same instance across threads. However, as noted in thehardware_detection.pyreview, theget_detector()function lacks thread-safe initialization. This test may pass due to the GIL in Python ≤3.13 but will likely fail under Python 3.14 free-threading (the stated target of this PR).Consider adding a note or skip condition, or ensure the singleton is fixed before these tests are relied upon for free-threading validation.
1-41: Comprehensive thread-safety test suite.The tests cover critical scenarios including singleton thread-safety, connection pool concurrent reads/writes, and stress testing. The use of
ThreadPoolExecutorwith high worker counts and the proper cleanup infinallyblocks are good practices.Also applies to: 66-182, 276-333
docs/PARALLEL_LLM_FREE_THREADING_DESIGN.md (2)
1-6: Well-structured design document for future implementation.The document clearly indicates it's a design document with "Implementation Pending" status. The architecture analysis, proposed improvements, and migration strategy are thorough and well-reasoned.
684-691: Robust free-threading detection logic.The detection uses multiple methods: checking
Py_GIL_DISABLEDconfig var and the runtimesys._is_gil_enabled()function. This provides good coverage for different Python 3.14+ builds and configurations.docs/PYTHON_314_THREAD_SAFETY_AUDIT.md (2)
1-30: Comprehensive thread-safety audit document.The audit correctly identifies critical issues including singleton races, unsafe SQLite usage, and file I/O without locks. The risk assessment matrix and phased implementation roadmap provide a clear path forward.
78-92: Audit accurately reflects the unfixedget_detector()issue.This section correctly identifies that
get_detector()inhardware_detection.pyhas a race condition. This aligns with the code review finding that this singleton is still not thread-safe despite other documentation claiming it's fixed.cortex/utils/db_pool.py (3)
19-96: Solid connection pool implementation with appropriate SQLite optimizations.The pool uses a queue-based design that's inherently thread-safe. The PRAGMA settings (WAL mode, NORMAL synchronous, 64MB cache, MEMORY temp store) are well-chosen for concurrent access scenarios. The
check_same_thread=Falsedefault is necessary for pool-based access across threads.
98-137: Well-implemented context manager with proper cleanup.The
get_connection()method correctly handles timeout with a descriptive error message, and always returns the connection to the pool in thefinallyblock. The overflow check (though it should never trigger) adds defensive logging.
181-222: Thread-safe singleton pattern correctly implemented.The
get_connection_pool()function uses double-checked locking properly: fast path without lock, then lock acquisition with re-check. This is the correct pattern for thread-safe lazy initialization.cortex/context_memory.py (4)
20-21: Correct migration to connection pooling.The import and initialization of the connection pool follow the established pattern. The database schema initialization correctly uses the pool context manager with proper commit.
Also applies to: 84-175
177-251: Database operations correctly use pool contexts.The
record_interactionandget_similar_interactionsmethods properly acquire connections from the pool and complete all database work within the context. The commit is correctly placed inside the context.
289-390: Pattern analysis and retrieval correctly use pooled connections.The
_analyze_patternsandget_patternsmethods properly use the connection pool. The INSERT ... ON CONFLICT pattern in_analyze_patternsis appropriate for the upsert operation.
510-673: Remaining database methods correctly migrated.All remaining methods (
_store_suggestion,get_active_suggestions,dismiss_suggestion,set_preference,get_preference,get_statistics,export_memory) properly use the connection pool with contexts that encompass all database operations before returning results.

1-24: LGTM!Module docstring, imports, and logger/console setup are well-organized and follow PEP 8 ordering (stdlib → third-party). The
getpassimport at module level addresses the previous review feedback.
38-67: Good implementation of lazy detection.The
auto_detectparameter with_detectedflag addresses the performance concerns raised in PR comments. Commands not requiring network can now passauto_detect=Falseand avoid the 2+ second startup delay.
68-94: LGTM!The
check_qualityparameter effectively addresses the performance concern about redundant network quality checks. Good use of early return pattern with_detectedflag.
222-253: LGTM!VPN detection logic is solid with good coverage of common VPN interface types. The empty
exceptclauses now have explanatory comments as previously requested.
349-363: LGTM!The pip proxy configuration now correctly handles both HTTP and HTTPS proxies with fallback, addressing the previous review feedback.
479-517: LGTM!The
auto_configuremethod provides good orchestration of the various configuration steps with appropriate handling for offline mode and connectivity failures.
586-613: LGTM!Good implementation with proper URL encoding for credentials and clear security warning in the docstring. The
noqa: S105 NOSONARcomment appropriately suppresses the false positive for the protocol prefix.
278-286: Bothhttps://8.8.8.8andhttps://1.1.1.1will fail with certificate errors.Neither Google's 8.8.8.8 nor Cloudflare's 1.1.1.1 serve TLS certificates valid for direct IP access. Google's certificate is issued for the
dns.googlehostname, and Cloudflare's certificates are issued forone.one.one.oneand other hostnames. Withverify=True(default), both IP-based endpoints will fail with SSL certificate name mismatch errors.Only
https://api.github.comin the list uses a hostname with a valid certificate and will succeed. Consider replacing both IP-based URLs with hostname-based endpoints or services specifically designed for DoH/DoT connectivity checks.Likely an incorrect or invalid review comment.

1-691: Comprehensive test suite with excellent coverage.The test suite demonstrates:
- Thorough coverage of NetworkConfig functionality (>80% as noted in PR objectives)
- Well-structured test classes organized by feature area
- Good edge case handling (missing files, permission errors, network failures, etc.)
- Appropriate mocking to isolate system dependencies
- Clear test names and docstrings for all test methods
The tests effectively validate the requirements from Issue #25 including proxy detection, VPN detection, connectivity checks, offline mode, and configuration methods.
However, please address the formatting issues (lines 607, 617, 691) and the mock_open pattern (line 172) flagged in other comments before merging.
