magic-folder 23.6.0

Magic Folder

This repository is provisional. It may move to a different organization.

Magic Folder for Tahoe-LAFS is a Free and Open file synchronization system. It detects local changes to files and uploads those changes to a Tahoe-LAFS grid. It monitors a Tahoe-LAFS grid and downloads changes to the local filesystem.

Installing

Usage

Magic-Folder is configured via the magic-folder command-line tool.

Magic-Folder configuration is kept in a directory. The default place for this directory is platform-dependant; on Linux it will be in ~/.config/magic-folder. Inside this directory is a database for global configuration and sub-directories to track state and temporary space for each actual magic-folder including a configuration database. All databases are SQLite.

A running Magic-Folder needs to have access to a Tahoe-LAFS client that it may use to perform operations in the Tahoe-LAFS Grid. This is referenced by the “node directory” of the Tahoe-LAFS client although actual operations are performed via the Tahoe-LAFS WebUI.

There are two ways to create a new Magic Folder instance (that is, the configuration required). Create a fresh one with magic-folder create or migrate from a Tahoe-LAFS 1.14.0 or earlier instance with magic-folder migrate.

Once a Magic-Folder is configured, functionality is provided by running a long-lived magic-folder daemon. This process is run using the magic-folder command line tool:

magic-folder --config <path to Magic Foler directory> run

As long as this process is running, whatever magic folders are configured will be functional. The process must be restarted to read configuration changes. All other interactions are via the HTTP API which listens on a local endpoint according to the configuration. Other magic-folder subcommands are typically just thin CLI wrappers around a particular HTTP endpoint.

Testing

To run the unit test suite:

• tox

You can pass arguments to trial with an environment variable. For example, you can run the test suite on multiple cores to speed it up:

• MAGIC_FOLDER_TRIAL_ARGS="-j4" tox

Documentation

Documentation is written as reStructuredText documents and processed using Sphinx; you will need sphinx and sphinx_rtd_theme. To generate HTML version of Magic Folder documents, do:

• cd docs; make html

Resulting HTML files will be under docs/_build/html/.
