swh.fuse.fuse module#

class swh.fuse.fuse.Fuse(cache: FuseCache, conf: Dict[str, Any], graph_backend: GraphBackend, obj_backend: ObjBackend)[source]#

Bases: Operations

Software Heritage Filesystem in Userspace (FUSE).

Locally mount parts of the archive and navigate it as a virtual file system.

This class ties together pyfuse3 and the configured cache and back-end.

shutdown() → None[source]#

inode2entry(inode: InodeT) → FuseEntry[source]#: Return the entry matching a given inode

async get_metadata(swhid: CoreSWHID) → Any[source]#: Retrieve metadata for a given SWHID using Software Heritage API

async get_blob(swhid: CoreSWHID) → bytes[source]#: Retrieve the blob bytes for a given content SWHID using Software Heritage API

async get_history(swhid: CoreSWHID) → List[CoreSWHID][source]#: Retrieve a revision’s history using Software Heritage Graph API

async get_visits(url_encoded: str) → List[Dict[str, Any]][source]#: Retrieve origin visits given an encoded-URL using Software Heritage API

async get_attrs(entry: FuseEntry) → EntryAttributes[source]#: Return entry attributes

async getattr(inode: InodeT, _ctx: RequestContext) → EntryAttributes[source]#: Get attributes for a given inode

async opendir(inode: InodeT, _ctx: RequestContext) → FileHandleT[source]#: Open a directory referred by a given inode

async readdir(fh: FileHandleT, offset: int, token: ReaddirToken) → None[source]#: Read entries in an open directory

async open(inode: InodeT, _flags: int, _ctx: RequestContext) → FileInfo[source]#: Open an inode and return a unique file handle

async read(fh: FileHandleT, offset: int, length: int) → bytes[source]#: Read length bytes from file handle fh at position offset

async lookup(parent_inode: InodeT, name: FileNameT, _ctx: RequestContext) → EntryAttributes[source]#: Look up a directory entry by name and get its attributes

async readlink(inode: InodeT, _ctx: RequestContext) → FileNameT[source]#

Return target of symbolic link inode.

ctx will be a RequestContext instance.

async unlink(parent_inode: InodeT, name: FileNameT, _ctx: RequestContext) → None[source]#: Remove a file
