Data Structures

llfuse.ENOATTR

This errorcode is unfortunately missing in the errno module, so it is provided by llfuse instead.

llfuse.ROOT_INODE

The inode of the root directory, i.e. the mount point of the file system.

exception llfuse.FUSEError(errno_)

This exception may be raised by request handlers to indicate that the requested operation could not be carried out. The system call that resulted in the request (if any) will then fail with error code errno_.

class llfuse.RequestContext

Instances of this class are passed to some Operations methods to provide information about the caller of the syscall that initiated the request.

pid

uid

gid

umask

class llfuse.StatvfsData

Instances of this class store information about the file system. The attributes correspond to the elements of the statvfs struct, see statvfs(2) for details.

Request handlers do not need to return objects that inherit from StatvfsData directly as long as they provide the required attributes.

f_bsize

f_frsize

f_blocks

f_bfree

f_bavail

f_files

f_ffree

f_favail

class llfuse.EntryAttributes

Instances of this class store attributes of directory entries. Most of the attributes correspond to the elements of the stat C struct as returned by e.g. fstat and should be self-explanatory.

The access, modification and creation times may be specified either in nanoseconds (via the st_Xtime_ns attributes) or in seconds (via the st_Xtime attributes). When times are specified both in seconds and nanoseconds, the nanosecond representation takes precedence. If times are represented in seconds, floating point numbers may be used to achieve sub-second resolution. Nanosecond time stamps must be integers. Note that using integer nanoseconds is more accurately than using float seconds.

Request handlers do not need to return objects that inherit from EntryAttributes directly as long as they provide the required attributes.

st_ino

generation

The inode generation number.

entry_timeout

Validity timeout (in seconds) for the name of the directory entry

attr_timeout

Validity timeout (in seconds) for the attributes

st_mode

st_nlink

st_uid

st_gid

st_rdev

st_size

st_blksize

st_blocks

st_atime

Time of access time in seconds. Floating point numbers may be used.

st_ctime

Time of last status change in seconds. Floating point numbers may be used.

st_mtime

Time of last modification in seconds. Floating point numbers may be used.

st_atime_ns

Time of last access in nanoseconds. Only integer values may be used. If specified, takes precedence over st_atime.

st_ctime_ns

Time of last status change in nanoseconds. Only integer values may be used. If specified, takes precedence over st_ctime.

st_mtime_ns

Time of last modification in nanoseconds. Only integer values may be used. If specified, takes precedence over st_mtime.
