### Publish a Static Website using CloudFiles Driver in Libcloud

Source: https://github.com/apache/libcloud/blob/trunk/docs/storage/examples.rst

This snippet shows how to configure a CloudFiles container to host a static website using Libcloud. This involves setting specific container metadata properties like 'X-Container-Meta-Web-Index' and 'X-Container-Meta-Web-Error'.

```python
from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver

# Replace with your CloudFiles details
provider = get_driver(Provider.CLOUDFILES)
conn = provider('your_username', 'your_api_key')

# Replace with your container name
container_name = 'my_static_website'

# Get or create the container
container = conn.get_container(container_name)

# Define metadata for static website hosting
# 'index.html' is the default index page
# 'error.html' is the default error page
website_metadata = {
    'X-Container-Meta-Web-Index': 'index.html',
    'X-Container-Meta-Web-Error': 'error.html'
}

# Update container metadata
# Note: Libcloud's update_container_metadata method might require
# passing the metadata directly or via an 'extra' dict depending on version.
# Check Libcloud documentation for the exact signature.

# Example using update_container_metadata (check Libcloud version/docs)
# Assuming it takes metadata directly:
# conn.update_container_metadata(container, website_metadata)

# Alternative: Using set_container_metadata (if available/appropriate)
# conn.set_container_metadata(container, website_metadata)

# A common pattern is to use the provider's specific method if available
# Or update via extra dict during container creation/update if supported.

# For demonstration, let's assume a direct update method exists or simulate it.
# In practice, you'd use the correct API call provided by your Libcloud version.

print(f"Attempting to configure container '{container.name}' for static website hosting...")
print("Please refer to Libcloud documentation for the exact method to update container metadata.")
# Example placeholder for the actual update call:
# try:
#     conn.update_container_metadata(container, website_metadata)
#     print(f"Container '{container.name}' configured for static website hosting.")
# except Exception as e:
#     print(f"Failed to configure container metadata: {e}")

# After configuration, upload your index.html, error.html, and other static files
# container.upload_object(object_name='index.html', file_path='/path/to/index.html')
# container.upload_object(object_name='error.html', file_path='/path/to/error.html')
# etc.
```

### Stream Directory Backup to CloudFiles using Libcloud

Source: https://github.com/apache/libcloud/blob/trunk/docs/storage/examples.rst

This snippet demonstrates creating a backup of a local directory and directly streaming the archive content to a CloudFiles container without saving the full archive locally. This is efficient for large backups.

```python
import os
import tarfile
from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver

# Replace with your CloudFiles details
provider = get_driver(Provider.CLOUDFILES)
conn = provider('your_username', 'your_api_key')

# Replace with your container name and directory path
container_name = 'my_backup_container'
directory_to_backup = '/path/to/directory'
object_name = 'backup.tar.gz'

# Get or create the container
container = conn.get_container(container_name)

# Create a tar.gz archive in memory and stream it
# This is a simplified example; actual implementation might use pipes or generators

# --- Simplified Streaming Logic (Conceptual) ---
# In a real scenario, you'd use a generator or pipe
# to stream data as it's being archived.
# For demonstration, we'll simulate streaming a file-like object.

class DirectoryTarStreamer:
    def __init__(self, directory_path):
        self.directory_path = directory_path
        # In a real implementation, this would be a streaming process
        # For this example, we'll just simulate reading from a dummy source
        self._data = b'Simulated tar.gz content of ' + directory_path.encode()
        self._pos = 0

    def read(self, size=-1):
        if self._pos >= len(self._data):
            return b''
        if size == -1:
            chunk = self._data[self._pos:]
            self._pos = len(self._data)
            return chunk
        else:
            chunk = self._data[self._pos : self._pos + size]
            self._pos += len(chunk)
            return chunk

    def __len__(self):
        # This is often required by upload methods
        # In a real streamer, you might not know the size beforehand
        # and might need to use chunked transfer encoding if the provider supports it.
        # For this example, we return a dummy size.
        return len(self._data)

# Create the streamer instance
streamer = DirectoryTarStreamer(directory_to_backup)

# Upload the stream
obj = container.upload_object_from_file(
    object_name=object_name,
    file=streamer,
    extra={}
)

print(f'Directory backup streamed to object {obj.name} in container {container.name}.')
# --- End Simplified Streaming Logic ---

### Working with Rackspace Performance Flavors (Python)

Source: https://github.com/apache/libcloud/blob/trunk/docs/compute/drivers/rackspace.rst

This example demonstrates how to interact with Rackspace 'performance' cloud server flavors using the next-generation driver. Performance flavors are currently available in specific regions (iad, ord, lon). The snippet likely involves listing available flavors or creating a server using a performance flavor.

```python
from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

# Replace with your credentials and a performance-flavor region
username = 'your_rackspace_username'
api_key = 'your_rackspace_api_key'
region = 'iad' # Example performance region (iad, ord, lon)

Driver = get_driver(Provider.RACKSPACE)
driver = Driver(username, api_key, region=region)

print(f"Listing flavors for region: {region}")
flavors = driver.list_sizes()

print("Available Flavors:")
for flavor in flavors:
    print(f"- ID: {flavor.id}, Name: {flavor.name}, RAM: {flavor.ram} MB, Disk: {flavor.disk} GB, Price: {flavor.price})")

# You would typically filter or select a performance flavor here
# Example: Find a flavor by name (performance1-1)
# performance_flavor = next((f for f in flavors if f.name == 'performance1-1'), None)
# if performance_flavor:
#     print(f"\nFound performance flavor: {performance_flavor.name}")
# else:
#     print("\nPerformance flavor not found.")
