funcNewDefaultFileSystem¶

func NewDefaultFileSystem()FileSystem

NewDefaultFileSystem creates a filesystem that responds ENOSYS forall methods

funcNewLockingFileSystem¶

func NewLockingFileSystem(pfsFileSystem)FileSystem

NewLockingFileSystem is a wrapper that makes a FileSystemthreadsafe by serializing each operation.

funcNewLoopbackFileSystem¶

func NewLoopbackFileSystem(rootstring)FileSystem

A FUSE filesystem that shunts all request to an underlying filesystem. Its main purpose is to provide test coverage withouthaving to build a synthetic filesystem.

funcNewPrefixFileSystem¶

func NewPrefixFileSystem(fsFileSystem, prefixstring)FileSystem

funcNewReadonlyFileSystem¶

func NewReadonlyFileSystem(fsFileSystem)FileSystem

NewReadonlyFileSystem returns a wrapper that only exposes read-onlyoperations.

type PathNodeFs struct {// contains filtered or unexported fields}

funcNewPathNodeFs¶

func NewPathNodeFs(fsFileSystem, opts *PathNodeFsOptions) *PathNodeFs

NewPathNodeFs returns a file system that translates from inodes topath names.

func (*PathNodeFs)AllFiles¶

func (fs *PathNodeFs) AllFiles(namestring, maskuint32) []nodefs.WithFlags

AllFiles returns all open files for the inode corresponding withthe given mask.

func (*PathNodeFs)Connector¶

func (fs *PathNodeFs) Connector() *nodefs.FileSystemConnector

Connector returns the FileSystemConnector (the bridge to the rawprotocol) for this PathNodeFs.

func (*PathNodeFs)EntryNotify¶

func (fs *PathNodeFs) EntryNotify(dirstring, namestring)fuse.Status

EntryNotify makes the kernel forget the entry data from the givenname from a directory. After this call, the kernel will issue anew lookup request for the given name when necessary.

func (*PathNodeFs)FileNotify¶

func (fs *PathNodeFs) FileNotify(pathstring, offint64, lengthint64)fuse.Status

FileNotify notifies that file contents were changed within thegiven range. Use negative offset for metadata-only invalidation,and zero-length for invalidating all content.

func (*PathNodeFs)ForgetClientInodes¶

func (fs *PathNodeFs) ForgetClientInodes()

ForgetClientInodes forgets all known information on client inodes.

func (*PathNodeFs)LastNode¶

func (fs *PathNodeFs) LastNode(namestring) (*nodefs.Inode, []string)

LastNode finds the deepest inode known corresponding to a path. Theunknown part of the filename is also returned.

func (*PathNodeFs)LookupNode¶

func (fs *PathNodeFs) LookupNode(namestring) *nodefs.Inode

Like Node, but use Lookup to discover inodes we may not have yet.

func (*PathNodeFs)Mount¶

func (fs *PathNodeFs) Mount(pathstring, rootnodefs.Node, opts *nodefs.Options)fuse.Status

Mount mounts a another node filesystem with the given root on thepath. The last component of the path should not exist yet.

func (*PathNodeFs)Node¶

func (fs *PathNodeFs) Node(namestring) *nodefs.Inode

Node looks up the Inode that corresponds to the given path name, orreturns nil if not found.

func (*PathNodeFs)Notify¶

func (fs *PathNodeFs) Notify(pathstring)fuse.Status

Notify ensures that the path name is invalidates: if the inode isknown, it issues an file content Notify, if not, an entry notifyfor the path is issued. The latter will clear out non-existencecache entries.

func (*PathNodeFs)Path¶

func (fs *PathNodeFs) Path(node *nodefs.Inode)string

Path constructs a path for the given Inode. If the file systemimplements hard links through client-inode numbers, the path maynot be unique.

func (*PathNodeFs)RereadClientInodes¶

func (fs *PathNodeFs) RereadClientInodes()

Rereads all inode numbers for all known files.

func (*PathNodeFs)Root¶

func (fs *PathNodeFs) Root()nodefs.Node

Root returns the root node for the path filesystem.

func (*PathNodeFs)SetDebug¶

func (fs *PathNodeFs) SetDebug(dbgbool)

SetDebug toggles debug information: it will log path names foreach operation processed.

func (*PathNodeFs)String¶

func (fs *PathNodeFs) String()string

String returns a name for this file system

func (*PathNodeFs)Unmount¶

func (fs *PathNodeFs) Unmount(pathstring)fuse.Status

UnmountNode unmounts the node filesystem with the given root.

func (*PathNodeFs)UnmountNode¶

func (fs *PathNodeFs) UnmountNode(node *nodefs.Inode)fuse.Status

UnmountNode unmounts the node filesystem with the given root.

type PathNodeFsOptions struct {// If ClientInodes is set, use Inode returned from GetAttr to// find hard-linked files.ClientInodesbool// Debug controls printing of debug information.Debugbool}
