Session Cache Fix

Problem Description

The system was exhibiting erratic session behavior:

  • Navigation was not smooth
  • Sometimes showed the login page
  • When trying to log in, showed a message that there was already an active session
  • After logging in and refreshing the page, sometimes showed the login button, sometimes showed the user menu

Root Cause

The issue was caused by cache key collision between authenticated and anonymous users.

How Flask-Caching Works

When using @cache.cached(unless=condition): - The unless parameter only controls whether to WRITE to cache - It does NOT control whether to READ from cache - All requests use the same cache key (e.g., view//home)

The Problem Flow

  1. Anonymous user visits /home
  2. Cache MISS
  3. Generates page with login button

  4. Caches it with key view//home

  5. Authenticated user visits /home

  6. unless returns True (don't cache for authenticated users)
  7. Checks cache first
  8. FINDS cached anonymous version

  9. Shows login button instead of user menu! ❌

  10. Authenticated user refreshes

  11. Sometimes gets fresh page (with user menu)
  12. Sometimes gets cached page (with login button)
  13. Erratic behavior! ❌

Solution

Use authentication-aware cache keys instead of relying on unless parameter.

New Cache Key Function

def cache_key_with_auth_state() -> str:
    """Generate cache key that includes authentication state.

    This ensures authenticated and anonymous users get different cached versions
    of the same page.
    """
    from flask import request

    # Include authentication state in the cache key
    auth_state = "auth" if (current_user and current_user.is_authenticated) else "anon"

    # Build key from request path and auth state
    key = f"view/{request.path}/{auth_state}"

    # Include query parameters if present
    if request.query_string:
        key += f"?{request.query_string.decode('utf-8')}"

    return key

Cache Keys Now Generated

User State Page Cache Key
Anonymous /home view//home/anon
Authenticated /home view//home/auth
Anonymous /course/explore?page=2 view//course/explore/anon?page=2
Authenticated /course/explore?page=2 view//course/explore/auth?page=2

Updated Decorator Usage

Before: 

@home.route("/home")
@cache.cached(timeout=90, unless=no_guardar_en_cache_global)
def pagina_de_inicio() -> str:
    ...

After: 

@home.route("/home")
@cache.cached(timeout=90, key_prefix=cache_key_with_auth_state)
def pagina_de_inicio() -> str:
    ...

Files Changed

  1. now_lms/cache.py
  2. Added cache_key_with_auth_state() function

  3. Kept no_guardar_en_cache_global() for backward compatibility

  4. now_lms/vistas/home.py

  5. Updated home page cache decorator

  6. now_lms/vistas/courses.py

  7. Updated 5 course view cache decorators

  8. now_lms/vistas/resources.py

  9. Updated 2 resource view cache decorators

  10. now_lms/vistas/programs.py

  11. Updated 2 program view cache decorators

  12. tests/test_session_cache_fix.py

  13. Added comprehensive tests for the fix

Testing

Unit Tests

pytest tests/test_session_cache_fix.py -v

Tests verify: - Cache keys differ for authenticated vs anonymous users - Cache keys include query parameters - Login/logout flow works correctly - No cache collisions between user states

Integration Tests

pytest tests/test_cache_invalidation.py tests/test_negative_simple.py -v

All existing cache tests still pass.

Manual Testing

  1. Visit home page as anonymous user → Should see login button
  2. Login → Should see user menu
  3. Refresh page → Should STILL see user menu (not login button)
  4. Logout → Should see login button
  5. Refresh page → Should STILL see login button (not user menu)

Benefits

✅ Smooth navigation - No more flickering between authenticated/anonymous states

✅ Consistent session - Users always see the correct state for their authentication

✅ Better performance - Can still cache pages, but separately per auth state

✅ Security - Prevents authenticated content from being cached for anonymous users

Backward Compatibility

The no_guardar_en_cache_global() function is kept for backward compatibility, but is no longer used in the main codebase. It can be removed in a future version after verifying no plugins or custom code depend on it.

Future Improvements

  1. Consider adding user-specific cache keys for highly personalized content
  2. Add cache warming for common pages
  3. Monitor cache hit rates for different authentication states
  4. Consider Redis-based session storage for better scalability

Gunicorn Session Storage Configuration

Problem

When switching from Waitress (single-threaded server) to Gunicorn (multi-process server), users experienced erratic session behavior:

  • Sometimes appeared logged in after authentication
  • Sometimes appeared logged out after refresh
  • "Already logged in" messages appeared inconsistently
  • UI flickered between authenticated and anonymous states

Root Cause

Gunicorn spawns multiple worker processes by default (e.g., gunicorn app:app --workers 4), and each worker has its own memory space. Flask's default session handling uses signed cookies stored in each process's memory, which causes issues:

  1. User logs in → Request handled by Worker 1 → Session created in Worker 1's memory
  2. User refreshes page → Request handled by Worker 2 → Worker 2 doesn't know about the session → User appears logged out
  3. User refreshes again → Request handled by Worker 1 → Session found → User appears logged in

This creates the "erratic" behavior where session state is inconsistent.

Solution

Implement shared session storage that all Gunicorn workers can access:

1. Redis (Preferred)

Redis provides optimal performance and is the recommended solution for production:

  • Fast in-memory storage
  • Shared across all workers
  • Persistent across server restarts
  • Supports session expiration

2. Filesystem (Fallback)

When Redis is not available, filesystem-based sessions work as long as all workers share the same filesystem:

  • Sessions stored in /tmp/now_lms_sessions/
  • Slower than Redis but functional
  • Works for single-server deployments

3. Testing Mode

During tests (when pytest is detected), the system uses Flask's default signed cookie sessions since tests run in a single process.

Configuration

Automatic Configuration

The system automatically detects the best available session storage:

# Priority order:
1. Redis (if REDIS_URL or SESSION_REDIS_URL is set)
2. Filesystem (if not in testing mode)
3. Default Flask sessions (for testing)

Redis Configuration

Set the Redis URL in your environment:

export REDIS_URL=redis://localhost:6379/0
# or
export SESSION_REDIS_URL=redis://localhost:6379/0

Then run Gunicorn:

gunicorn "now_lms:lms_app" --workers 4 --bind 0.0.0.0:8000

Without Redis

If Redis is not available, the system will automatically use filesystem storage. No configuration needed.

SECRET_KEY (Critical!)

ALWAYS set a stable SECRET_KEY in production:

export SECRET_KEY="your-long-random-secret-key-here"

⚠️ Never use the default "dev" SECRET_KEY in production! This will cause session issues even with shared storage.

Generate a secure key:

python -c "import secrets; print(secrets.token_hex(32))"

Session Settings

All session storage backends use these production-ready settings:

  • SESSION_PERMANENT: False (sessions expire when browser closes, but PERMANENT_SESSION_LIFETIME still applies)
  • SESSION_USE_SIGNER: True (sessions are cryptographically signed for security)
  • PERMANENT_SESSION_LIFETIME: 86400 seconds (24 hours)
  • SESSION_KEY_PREFIX: "session:" (for Redis, to namespace keys)
  • SESSION_COOKIE_HTTPONLY: True (prevents JavaScript access to session cookie)
  • SESSION_COOKIE_SECURE: True in production (enforces HTTPS)
  • SESSION_COOKIE_SAMESITE: "Lax" (protects against CSRF attacks)
  • SESSION_FILE_THRESHOLD: 1000 (maximum number of sessions before cleanup)

Files Modified

  1. requirements.txt: Added flask-session dependency
  2. now_lms/session_config.py: Session configuration with cookie security settings
  3. now_lms/__init__.py: Integrated session initialization
  4. now_lms/config/__init__.py: Added SECRET_KEY warning
  5. run.py: Gunicorn configuration with preload_app=True for shared sessions (for containers)
  6. now_lms/cli.py: Gunicorn configuration with preload_app=True for shared sessions (for CLI)

Testing

Run the session configuration tests:

pytest tests/test_session_gunicorn.py -v

Tests verify: - Redis configuration when REDIS_URL is set - Filesystem fallback when Redis is unavailable - Proper settings for production use - Session persistence across requests

Gunicorn Configuration

NOW LMS has built-in Gunicorn configuration in run.py and now_lms/cli.py with optimal settings for session handling:

# Key configurations for session support
options = {
    "preload_app": True,  # Load app before forking workers
    "workers": workers,  # Intelligent calculation based on CPU and RAM
    "threads": threads,  # Default 1 for filesystem, can be >1 with Redis
    "worker_class": "gthread" if threads > 1 else "sync",
    "graceful_timeout": 30,
}

Important: - preload_app = True ensures consistent app configuration across all workers - Use threads = 1 when using filesystem sessions for compatibility - Use threads > 1 only when using Redis for sessions - Worker/thread counts are automatically calculated based on system resources

Gunicorn Best Practices

Using the CLI Command

The recommended way to run NOW LMS is using the built-in CLI:

lmsctl serve

Or directly with Python:

python run.py

Both commands automatically configure Gunicorn with: - preload_app = True for memory efficiency and shared sessions - Intelligent worker/thread calculation based on CPU and RAM - Environment variable overrides (GUNICORN_WORKERS, GUNICORN_THREADS)

Basic Command

gunicorn "now_lms:lms_app" --workers 4 --threads 2 --bind 0.0.0.0:8000

With Environment Variables

export SECRET_KEY="your-secret-key"
export REDIS_URL="redis://localhost:6379/0"
export DATABASE_URL="postgresql://user:pass@localhost/dbname"
export GUNICORN_WORKERS=4
export GUNICORN_THREADS=2

# Using the CLI command
lmsctl serve

# Or using run.py
python run.py

Direct Gunicorn Command (Advanced)

gunicorn "now_lms:lms_app" --workers 4 --bind 0.0.0.0:8000

Note: Using the CLI command or run.py is recommended as they include the preload_app=True setting automatically.

Worker Count

Choose worker count based on your server:

  • CPU-bound: workers = (2 × CPU cores) + 1
  • I/O-bound: workers = (4 × CPU cores) + 1

Example for 4 CPU cores: 

gunicorn "now_lms:lms_app" --workers 9 --bind 0.0.0.0:8000

With Timeout

gunicorn "now_lms:lms_app" --workers 4 --timeout 120 --bind 0.0.0.0:8000

Monitoring

Check logs for session configuration:

INFO: Configuring Redis-based session storage for Gunicorn workers
INFO: Session storage initialized: redis
INFO: Using Redis for session storage - optimal for Gunicorn

or

INFO: Configuring filesystem-based session storage for Gunicorn workers
INFO: Session storage initialized: filesystem
INFO: Session directory: /tmp/now_lms_sessions

Troubleshooting

Sessions still erratic with Redis

  1. Verify Redis is running: redis-cli ping (should return "PONG")
  2. Check Redis URL is correct: echo $REDIS_URL
  3. Verify SECRET_KEY is set and stable: echo $SECRET_KEY
  4. Check Gunicorn logs for session initialization messages

Sessions not persisting

  1. Check SECRET_KEY is not "dev": echo $SECRET_KEY
  2. If using filesystem storage, verify /tmp/now_lms_sessions is writable
  3. Check session expiration (default 24 hours)

Redis connection errors

If Redis is configured but not available:

# Temporarily disable Redis to use filesystem fallback
unset REDIS_URL
unset SESSION_REDIS_URL

Migration from Waitress

When migrating from Waitress to Gunicorn:

  1. Set SECRET_KEY (if not already set)
  2. Install Redis (recommended) or accept filesystem fallback
  3. Update deployment command from waitress-serve to gunicorn
  4. Test with multiple workers to verify session persistence

Performance

Redis vs Filesystem

Feature Redis Filesystem
Speed Very Fast Moderate
Scalability Excellent Limited
Multi-server Yes No
Persistence Configurable Yes
Setup Requires Redis No setup

Recommendations

  • Single server, low traffic: Filesystem is sufficient
  • Single server, high traffic: Use Redis
  • Multiple servers: Use Redis (required)
  • Development: Either works
  • Testing: Automatic (no configuration needed)

Security Notes

  1. Always use HTTPS in production - sessions are transmitted in cookies
  2. Set SECRET_KEY to a strong, random value - never use "dev"
  3. Enable SESSION_USE_SIGNER (automatic) - prevents session tampering
  4. Use Redis with authentication if exposed to network
  5. Rotate SECRET_KEY periodically - invalidates all sessions

Fixing lmsctl serve on Windows: A CLI Context Blocking Issue

Date: October 5, 2025 Category: Bug Fix Affected Platforms: Windows

The Problem

Windows users of NOW-LMS encountered a frustrating issue when trying to start the development server using the lmsctl serve command. Instead of the server starting normally, they would see this cryptic error message:

* Ignoring a call to 'app.run()' that would block the current 'flask' CLI command.
  Only call 'app.run()' in an 'if __name__ == "__main__"' guard.

The server simply wouldn't start, making it impossible to run NOW-LMS on Windows through the standard CLI interface. This was particularly problematic for developers and instructors who needed to run the platform on Windows machines for training or development purposes.

RAM Optimization Guide for NOW LMS

This guide explains how NOW LMS automatically optimizes RAM usage through intelligent worker and thread configuration for Gunicorn.

Overview

NOW LMS implements RAM-aware worker configuration that automatically calculates the optimal number of workers and threads based on:

  • Available system RAM
  • Number of CPU cores
  • Estimated memory per worker
  • Thread configuration

This ensures the application doesn't consume more RAM than available, preventing crashes and performance issues.

Environment Variable Validation for Custom Directories

Date: September 19, 2025 Feature: Custom Data and Theme Directory Support

Overview

NOW-LMS now properly validates and respects the NOW_LMS_DATA_DIR and NOW_LMS_THEMES_DIR environment variables, allowing for custom directory configurations for system data and themes. This feature enhances deployment flexibility and supports containerized environments.

Environment Variables Supported

NOW_LMS_DATA_DIR

  • Purpose: Specifies a custom directory for application data files
  • Default: now_lms/static (relative to application directory)
  • Example: export NOW_LMS_DATA_DIR=/var/lib/now-lms/data

NOW_LMS_THEMES_DIR

  • Purpose: Specifies a custom directory for theme templates
  • Default: now_lms/templates (relative to application directory)
  • Example: export NOW_LMS_THEMES_DIR=/var/lib/now-lms/themes

How It Works

  1. Environment Detection: The system checks for these environment variables at startup
  2. Directory Creation: If custom directories are specified, they are automatically created
  3. Content Population: Default data and themes are copied to custom directories if they don't exist or are empty
  4. Automatic Initialization: The populate functions run at every app startup when environment variables are detected

Implementation Details

Populate Functions

The system includes two key functions that handle directory population:

  • populate_custmon_data_dir(): Copies default static files to custom data directory
  • populate_custom_theme_dir(): Copies default templates to custom theme directory

Integration with App Initialization

The init_app() function now calls these populate functions whenever: - The database is already initialized - Custom environment variables are detected - This ensures custom directories are always properly populated

Testing and Validation

Comprehensive Test Suite

New tests have been added to validate: - Custom data directory creation and population - Custom theme directory creation and population - Integration with the app initialization process - Environment variable cleanup for testing

Test Environment Safety

The test environment properly unsets environment variables to prevent test interference: - dev/test.sh now clears all environment variables before running tests - Individual tests use isolated environments with proper cleanup

Usage Examples

Docker Deployment

ENV NOW_LMS_DATA_DIR=/app/data
ENV NOW_LMS_THEMES_DIR=/app/themes
VOLUME ["/app/data", "/app/themes"]

Systemd Service

[Service]
Environment="NOW_LMS_DATA_DIR=/var/lib/now-lms/data"
Environment="NOW_LMS_THEMES_DIR=/var/lib/now-lms/themes"
ExecStart=/usr/bin/lmsctl serve

Development Setup

export NOW_LMS_DATA_DIR="$HOME/lms-dev/data"
export NOW_LMS_THEMES_DIR="$HOME/lms-dev/themes"
lmsctl serve

Benefits

  1. Deployment Flexibility: Support for containerized and multi-tenant deployments
  2. Data Separation: Clean separation between application code and user data
  3. Theme Customization: Easy theme customization without modifying application files
  4. Backup and Migration: Simplified data backup and migration procedures
  5. Security: Better file system security with dedicated directories

Directory Structure

When custom directories are used, the following structure is created:

$NOW_LMS_DATA_DIR/
├── files/
│   ├── public/
│   └── private/
├── img/
├── icons/
└── examples/

$NOW_LMS_THEMES_DIR/
├── admin/
├── blog/
├── course/
├── evaluation/
└── [other template directories]

Backward Compatibility

This feature maintains full backward compatibility: - Systems without environment variables continue to use default directories - Existing installations are unaffected - No configuration changes required for current deployments

Future Enhancements

Potential future improvements include: - Support for additional directory customizations - Configuration validation and error reporting - Directory migration tools - Performance optimization for large custom directories

This enhancement provides NOW-LMS with enterprise-grade deployment flexibility while maintaining simplicity for development and testing environments.
