Data Structures — Python-LLFUSE 1.5.1 documentation

# Data Structures

llfuse.ENOATTR

  This errorcode is unfortunately missing in the `errno` module, so it is provided by Python-LLFUSE instead.

llfuse.ROOT_INODE

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

llfuse.default_options

  This is a recommended set of options that should be passed to `llfuse.init` to get reasonable behavior and performance. Python-LLFUSE is compatible with any other combination of options as well, but you should only deviate from the defaults with good reason.

  (The `fsname=<foo>` option is guaranteed never to be included in the default options, so you can always safely add it to the set).

  New in version 0.42.

exception llfuse.FUSEError

  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.

  f_bsize
  f_frsize
  f_blocks
  f_bfree
  f_bavail
  f_files
  f_ffree
  f_favail
  f_namemax

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.

  st_ino
  generation

    The inode generation number

  entry_timeout

    Validity timeout for the name/existence of the directory entry

    Floating point numbers may be used. Units are seconds.

  attr_timeout

    Validity timeout for the attributes of the directory entry

    Floating point numbers may be used. Units are seconds.

  st_mode
  st_nlink
  st_uid
  st_gid
  st_rdev
  st_size
  st_blksize
  st_blocks
  st_atime_ns

    Time of last access in (integer) nanoseconds

  st_ctime_ns

    Time of last inode modification in (integer) nanoseconds

  st_mtime_ns

    Time of last modification in (integer) nanoseconds

class llfuse.SetattrFields

  `SetattrFields` instances are passed to the `setattr` handler to specify which attributes should be updated.

  update_atime

    If this attribute is true, it signals the `Operations.setattr` method that the `st_atime_ns` field contains an updated value.

  update_mtime

    If this attribute is true, it signals the `Operations.setattr` method that the `st_mtime_ns` field contains an updated value.

  update_mode

    If this attribute is true, it signals the `Operations.setattr` method that the `st_mode` field contains an updated value.

  update_uid

    If this attribute is true, it signals the `Operations.setattr` method that the `st_uid` field contains an updated value.

  update_gid

    If this attribute is true, it signals the `Operations.setattr` method that the `st_gid` field contains an updated value.

  update_size

    If this attribute is true, it signals the `Operations.setattr` method that the `st_size` field contains an updated value.
