A filesystem API that uses paths rather than inodes. A minimal file system should have at least a functional GetAttr method. Typically, each call happens in its own goroutine, so take care to make the file system thread-safe.

Include DefaultFileSystem to provide a default null implementation of required methods.

type FileSystemConnector 

type FileSystemConnector struct {
	DefaultRawFileSystem

	Debug bool
	// contains filtered or unexported fields
}

FilesystemConnector is a raw FUSE filesystem that manages in-process mounts and inodes. Its job is twofold:

* It translates between the raw kernel interface (padded structs of int32 and int64) and the more abstract Go-ish NodeFileSystem interface.

* It manages mounting and unmounting of NodeFileSystems into the directory hierarchy

To achieve this, the connector only needs a pointer to the root node.

func (*FileSystemConnector) Mount 

func (me *FileSystemConnector) Mount(parent *Inode, name string, nodeFs NodeFileSystem, opts *FileSystemOptions) Status

Mount() generates a synthetic directory node, and mounts the file system there. If opts is nil, the mount options of the root file system are inherited. The encompassing filesystem should pretend the mount point does not exist. If it does, it will generate an Inode with the same, which will cause Mount() to return EBUSY.

Return values:

ENOENT: the directory containing the mount point does not exist.

EBUSY: the intended mount point already exists.

	// If set, replace all uids with given UID.
	// NewFileSystemOptions() will set this to the daemon's
	// uid/gid.
	*Owner

	// If set, use a more portable, but slower inode number
	// generation scheme.  This will make inode numbers (exported
	// back to callers) stay within int32, which is necessary for
	// making stat() succeed in 32-bit programs.
	PortableInodes bool

MountOptions contains time out options for a (Node)FileSystem. The default copied from libfuse and set in NewMountOptions() is (1s,1s,0s).

}

HandleMap translates objects in Go space to 64-bit handles that can be given out to -say- the linux kernel. It uses the free bits on x64_64 (16+3) to do an extra sanity check on the data. (Thanks to Russ Cox for this suggestion). In addition, it stores the object in a map, so the Go runtime will not garbage collect it.

The 32 bits version of this is a threadsafe wrapper around a map.

To use it, include Handled as first member of the structure you wish to export.

This structure is thread-safe.

func NewHandleMap 

func NewHandleMap(portable bool) (hm HandleMap)

NewHandleMap creates a new HandleMap. If verify is given, we use remaining bits in the handle to store sanity check bits.

}

type MountState 

type MountState struct {

type NodeFileSystem 

type NodeFileSystem interface {
	OnUnmount()

	// Used for debug outputs
	String() string
}

NodeFileSystem is a high level API that resembles the kernel's idea of what an FS looks like. NodeFileSystems can have multiple hard-links to one file, for example. It is also suited if the data to represent fits in memory: you can construct FsNode at mount time, and the filesystem will be ready.

type PathNodeFs 

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

PathNodeFs is the file system that can translate an inode back to a path. The path name is then used to call into an object that has the FileSystem interface.

Lookups (ie. FileSystem.GetAttr) may return a inode number in its return value. The inode number ("clientInode") is used to indicate linked files. The clientInode is never exported back to the kernel; it is only used to maintain a list of all names of an inode.

}

RawFileSystem is an interface close to the FUSE wire protocol.

Unless you really know what you are doing, you should not implement this, but rather the FileSystem interface; the details of getting interactions with open files, renames, and threading right etc. are somewhat tricky and not very interesting.

Include DefaultRawFileSystem to inherit a null implementation.

type RawFsInit 

type RawFsInit struct {
	InodeNotify func(*NotifyInvalInodeOut) Status
	EntryNotify func(parent uint64, name string) Status
}

Talk back to FUSE.

InodeNotify invalidates the information associated with the inode (ie. data cache, attributes, etc.)

EntryNotify should be used if the existence status of an entry changes, (ie. to notify of creation or deletion of the file).

Somewhat confusingly, InodeNotify for a file that stopped to exist will give the correct result for Lstat (ENOENT), but the kernel will still issue file Open() on the inode.
