17. Layer python3

17.1. Overview

The layer1_python3 layer includes Python3 MFSERV packages.

For asyncio and aiohttp python web server implementation, it also provides mechanism for customizing request handlers via middleware. Currently, this layer provides :

• a timeout middleware which returns a context manager that cancels the request on timeout expiring (see asyncio-compatible timeout context manager documentation)

• a log middleware which adds into the log, the unique request ID from the HTTP header X-Request-ID attributes.

The layer1_python3 layer is included in the .layerapi2_dependencies file of the plugin when you choose python3 during the creation of a plugin.

You may also manually include this dependencies (i.e. Label) in the .layerapi2_dependencies file.
