Functions ¶

func NewDirectory ¶

func NewDirectory(uid, gid uint32, tree *gitfstree.TreeNode, cloner *urls.FileSystemAdapter) fs.Node

NewDirectory constructs a new directory object using the supplied parameters.

Types ¶

type BillyNode ¶

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

BillyNode is used to represent a node in a directory structure. It implements INode which defines all methods needed to be implemented by the FUSE file system.

func (n *BillyNode) Attr(ctx context.Context, attr *fuse.Attr) error

Attr description.

func (*BillyNode) Create ¶

func (n *BillyNode) Create(ctx context.Context, req *fuse.CreateRequest, resp *fuse.CreateResponse) (fs.Node, fs.Handle, error)

Create description.

func (*BillyNode) Flush ¶

func (n *BillyNode) Flush(ctx context.Context, req *fuse.FlushRequest) error

Flush description.

func (*BillyNode) Fsync ¶

func (n *BillyNode) Fsync(ctx context.Context, req *fuse.FsyncRequest) error

Fsync description.

func (*BillyNode) Lookup ¶

func (n *BillyNode) Lookup(ctx context.Context, name string) (fs.Node, error)

Lookup description.

func (*BillyNode) ReadDirAll ¶

func (n *BillyNode) ReadDirAll(ctx context.Context) ([]fuse.Dirent, error)

ReadDirAll description.

func (*BillyNode) Readlink ¶

func (n *BillyNode) Readlink(ctx context.Context, req *fuse.ReadlinkRequest) (string, error)

Readlink description.

func (*BillyNode) Release ¶

func (n *BillyNode) Release(ctx context.Context, req *fuse.ReleaseRequest) error

Release description.

func (*BillyNode) Remove ¶

func (n *BillyNode) Remove(ctx context.Context, req *fuse.RemoveRequest) error

Remove description.

func (*BillyNode) Rename ¶

func (n *BillyNode) Rename(ctx context.Context, req *fuse.RenameRequest, newDir fs.Node) error

Rename description.

func (*BillyNode) Setattr ¶

func (n *BillyNode) Setattr(ctx context.Context, req *fuse.SetattrRequest, resp *fuse.SetattrResponse) error

Setattr description.

func (*BillyNode) Symlink ¶

func (n *BillyNode) Symlink(ctx context.Context, req *fuse.SymlinkRequest) (fs.Node, error)

Symlink description.

func (*BillyNode) Write ¶

func (n *BillyNode) Write(ctx context.Context, req *fuse.WriteRequest, resp *fuse.WriteResponse) error

Write description.

type BillyUser ¶

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

BillyUser is used to encapsulate the user id and group id across nodes.

type Directory ¶

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

Directory represents a read only directory within the immutable repository tree.

func (*Directory) Attr ¶

func (d *Directory) Attr(ctx context.Context, attr *fuse.Attr) error

Attr description.

func (*Directory) Lookup ¶

func (d *Directory) Lookup(ctx context.Context, name string) (fs.Node, error)

Lookup description.

func (*Directory) ReadDirAll ¶

func (d *Directory) ReadDirAll(ctx context.Context) ([]fuse.Dirent, error)

ReadDirAll description.

type FileSystem ¶

type FileSystem struct {
	UID  uint32
	GID  uint32
	Tree *gitfstree.TreeNode
	FSA  *urls.FileSystemAdapter
}

FileSystem defines the root of the directory tree.

func (*FileSystem) Root ¶

func (f *FileSystem) Root() (fs.Node, error)

Root returns the root of the directory tree.

type INode ¶

type INode interface {
	// node functions
	fs.Node
	fs.NodeSetattrer

	// directory functions
	fs.NodeStringLookuper
	fs.HandleReadDirAller
	fs.NodeMkdirer
	fs.NodeCreater
	fs.NodeRemover
	fs.NodeRenamer
	fs.NodeSymlinker

	// handle functions
	fs.NodeOpener
	fs.HandleWriter
	fs.HandleReader
	fs.NodeFsyncer
	fs.HandleFlusher
	fs.HandleReleaser

	// symlink functions
	fs.NodeReadlinker
}

INode encapsulates all the functionality that should be implemented to emulate an inode in unix file systems. I managed to stumble across this in a cockroachdb project, but can no longer find the reference.
