Media Repository
|
|
================
|
|
|
|
The media repository is where attachments and avatar photos are stored.
|
|
It stores attachment content and thumbnails for media uploaded by local users.
|
|
It caches attachment content and thumbnails for media uploaded by remote users.
|
|
|
|
Storage
|
|
-------
|
|
|
|
Each item of media is assigned a ``media_id`` when it is uploaded.
|
|
The ``media_id`` is a randomly chosen, URL safe 24 character string.
|
|
Metadata such as the MIME type, upload time and length are stored in the
|
|
sqlite3 database indexed by ``media_id``.
|
|
Content is stored on the filesystem under a "content" directory. Thumbnails are
|
|
stored under a "thumbnails" directory.
|
|
The item with ``media_id`` ``"aabbccccccccdddddddddddd"`` is stored under
|
|
``"local/content/aa/bb/ccccccccdddddddddddd"``. Its thumbnail with width
|
|
``128`` and height ``96`` and type ``"image/jpeg"`` is stored under
|
|
``"local/thumbnails/aa/bb/ccccccccdddddddddddd/128-96-image-jpeg"``
