When top-level AND conjuncts pin the query to a single root (driveId/RootID restrictions), only that space's index is asked; the restriction itself stays in the query, so this is purely an optimization. Conservative by design: any top-level OR, negated or group-nested restriction leaves the fan-out untouched, searching a space too many is wasted work while skipping one would be wrong. Mountpoints are kept for result path mapping. Costs one extra parse of the query in the service; parsing once and handing the AST to the engines (which currently re-parse per space) is a follow-up that changes the engine interface.
Server Backend
Tip
For general information about OpenCloud and how to install please visit OpenCloud on Github and OpenCloud GmbH.
This is the main repository of the OpenCloud server. It contains the golang codebase for the backend services.
Getting Involved
The OpenCloud server is released under Apache 2.0. The project is thrilled to receive contributions in all forms. Start hacking now, there are many ways to get involved such as:
- Reporting issues or bugs
- Requesting features
- Writing documentation
- Writing code or extend our tests
- Reviewing code
- Helping others in the community
Every contribution is meaningful and appreciated! Please refer to our Contribution Guidelines if you want to get started.
Build OpenCloud
To build the backend, follow these instructions:
Generate the assets needed by e.g., the web UI and the builtin IDP
make generate
Then compile the opencloud binary
make -C opencloud build
That will produce the binary opencloud/bin/opencloud. It can be started as a local test instance right away with a two step command:
opencloud/bin/opencloud init && opencloud/bin/opencloud server
This creates a server configuration (by default in $HOME/.opencloud) and starts the server.
For more setup- and installation options consult the Development Documentation.
Technology
Important information for contributors about the technology in use.
Authentication
The OpenCloud backend authenticates users via OpenID Connect using either an external IdP like Keycloak or the embedded LibreGraph Connect identity provider.
Database
The OpenCloud backend does not use a database. It stores all data in the filesystem. By default, the root directory of the backend is $HOME/.opencloud/.
Security
