backend.storage Namespace Reference

Variables
	backend
	IS_S3 = isinstance(backend, S3Backend)

Detailed Description

Version storage for engine designs: microversions + immutable releases.

A thin binding of :mod:`stardesign.storage` to this app's S3 environment. The
module-level ``backend`` and ``IS_S3`` names are what the rest of this backend
imports, so they stay.

Design version history in S3 when ``ENGINE_S3_BUCKET`` is set; files on the
``USERDATA_DIR`` volume otherwise (dev, and prod with no bucket).
