Documents¶

Description¶

Document portal

The document portal allows to make files from the outside world available to sandboxed applications in a controlled way.

Exported files will be made accessible to the application via a fuse filesystem that gets mounted at /run/user/$UID/doc/. The filesystem gets mounted both outside and inside the sandbox, but the view inside the sandbox is restricted to just those files that the application is allowed to access.

Individual files will appear at /run/user/$UID/doc/$DOC_ID/filename, where $DOC_ID is the ID of the file in the document store. It is returned by the org.freedesktop.portal.Documents.Add and org.freedesktop.portal.Documents.AddNamed calls.

The permissions that the application has for a document store entry (see org.freedesktop.portal.Documents.GrantPermissions) are reflected in the POSIX mode bits in the fuse filesystem.

The D-Bus interface for the document portal is available under the bus name org.freedesktop.portal.Documents and the object path /org/freedesktop/portal/documents.

This documentation describes version 4 of this interface.

Methods¶

org.freedesktop.portal.Documents.GetMountPoint¶

GetMountPoint (
  OUT path ay
)

Returns the path at which the document store fuse filesystem is mounted. This will typically be /run/user/$UID/doc/.

path: the path at which the fuse filesystem is mounted

org.freedesktop.portal.Documents.Add¶

Add (
  IN o_path_fd h,
  IN reuse_existing b,
  IN persistent b,
  OUT doc_id s
)

Adds a file to the document store. The file is passed in the form of an open file descriptor to prove that the caller has access to the file.

o_path_fd: open file descriptor for the file to add
reuse_existing: whether to reuse an existing document store entry for the file
persistent: whether to add the file only for this session or permanently
doc_id: the ID of the file in the document store

org.freedesktop.portal.Documents.AddNamed¶

AddNamed (
  IN o_path_parent_fd h,
  IN filename ay,
  IN reuse_existing b,
  IN persistent b,
  OUT doc_id s
)

Creates an entry in the document store for writing a new file.

o_path_parent_fd: open file descriptor for the parent directory
filename: the basename for the file
reuse_existing: whether to reuse an existing document store entry for the file
persistent: whether to add the file only for this session or permanently
doc_id: the ID of the file in the document store

org.freedesktop.portal.Documents.AddFull¶

AddFull (
  IN o_path_fds ah,
  IN flags u,
  IN app_id s,
  IN permissions as,
  OUT doc_ids as,
  OUT extra_out a{sv}
)

Adds multiple files to the document store. The file is passed in the form of an open file descriptor to prove that the caller has access to the file.

If the as-needed-by-app flag is given, files will only be added to the document store if the application does not already have access to them. For files that are not added to the document store, the doc_ids array will contain an empty string.

Additionally, if app_id is specified, it will be given the permissions listed in org.freedesktop.portal.Documents.GrantPermissions.

The method also returns some extra info that can be used to avoid multiple roundtrips. For now it only contains as “mountpoint”, the fuse mountpoint of the document portal.

This method was added in version 2 of this interface.

Support for exporting directories was added in version 4 of this interface.

o_path_fds: open file descriptors for the files to export
flags: flags, 1 == reuse_existing, 2 == persistent, 4 == as-needed-by-app, 8 = export-directory
app_id: an application ID, or empty string
permissions: the permissions to grant, possible values are ‘read’, ‘write’, ‘grant-permissions’ and ‘delete’
doc_ids: the IDs of the files in the document store

extra_out

org.freedesktop.portal.Documents.AddNamedFull¶

AddNamedFull (
  IN o_path_fd h,
  IN filename ay,
  IN flags u,
  IN app_id s,
  IN permissions as,
  OUT doc_id s,
  OUT extra_out a{sv}
)

Creates an entry in the document store for writing a new file.

If the as-needed-by-app flag is given, file will only be added to the document store if the application does not already have access to it. For file that is not added to the document store, the doc_id will contain an empty string.

Additionally, if app_id is specified, it will be given the permissions listed in org.freedesktop.portal.Documents.GrantPermissions.

The method also returns some extra info that can be used to avoid multiple roundtrips. For now it only contains as “mountpoint”, the fuse mountpoint of the document portal.

This method was added in version 3 of this interface.

o_path_fd

filename: the basename for the file
flags: flags, 1 == reuse_existing, 2 == persistent, 4 == as-needed-by-app
app_id: an application ID, or empty string
permissions: the permissions to grant, possible values are ‘read’, ‘write’, ‘grant-permissions’ and ‘delete’
doc_id: the ID of the file in the document store

extra_out

org.freedesktop.portal.Documents.GrantPermissions¶

GrantPermissions (
  IN doc_id s,
  IN app_id s,
  IN permissions as
)

Grants access permissions for a file in the document store to an application.

This call is available inside the sandbox if the application has the grant-permissions permission for the document.

doc_id: the ID of the file in the document store
app_id: the ID of the application to which permissions are granted
permissions: the permissions to grant, possible values are read, write, grant-permissions and delete

org.freedesktop.portal.Documents.RevokePermissions¶

RevokePermissions (
  IN doc_id s,
  IN app_id s,
  IN permissions as
)

Revokes access permissions for a file in the document store from an application.

This call is available inside the sandbox if the application has the grant-permissions permission for the document.

doc_id: the ID of the file in the document store
app_id: the ID of the application from which permissions are revoked
permissions: the permissions to revoke, possible values are ‘read’, ‘write’, ‘grant-permissions’ and ‘delete’

org.freedesktop.portal.Documents.Delete¶

Delete (
  IN doc_id s
)

Removes an entry from the document store. The file itself is not deleted.

This call is available inside the sandbox if the application has the delete permission for the document.

doc_id: the ID of the file in the document store

org.freedesktop.portal.Documents.Lookup¶

Lookup (
  IN filename ay,
  OUT doc_id s
)

Looks up the document ID for a file.

This call is not available inside the sandbox.

filename: a path in the host filesystem
doc_id: the ID of the file in the document store, or ‘’ if the file is not in the document store

org.freedesktop.portal.Documents.Info¶

Info (
  IN doc_id s,

  OUT apps a{sas}
)

Gets the filesystem path and application permissions for a document store entry.

This call is not available inside the sandbox.

doc_id: the ID of the file in the document store
path: the path for the file in the host filesystem
apps: a dictionary mapping application IDs to the permissions for that application

org.freedesktop.portal.Documents.List¶

List (
  IN app_id s,
  OUT docs a{say}
)

Lists documents in the document store for an application (or for all applications).

This call is not available inside the sandbox.

app_id: an application ID, or ‘’ to list all documents
docs: a dictionary mapping document IDs to their filesystem path
