Change the owner (``uid``) and group (``gid``) of this file. As with

Set the access and modified times of this file. If
``times`` is ``None``, then the file's access and modified times are set
to the current time. Otherwise, ``times`` must be a 2-tuple of numbers,
of the form ``(atime, mtime)``, which is used to set the access and
modified times, respectively. This bizarre API is mimicked from Python
for the sake of consistency -- I apologize.

Ask the server for a hash of a section of this file. This can be used
to verify a successful upload or download, or for various rsync-like
operations.
The file is hashed from ``offset``, for ``length`` bytes. If ``length``
is 0, the remainder of the file is hashed. Thus, if both ``offset``
and ``length`` are zero, the entire file is hashed.
Normally, ``block_size`` will be 0 (the default), and this method will
return a byte string representing the requested hash (for example, a
string of length 16 for MD5, or 20 for SHA-1). If a non-zero
``block_size`` is given, each chunk of the file (from ``offset`` to
``offset + length``) of ``block_size`` bytes is computed as a separate
hash. The hash results are all concatenated and returned as a single
string.
For example, ``check('sha1', 0, 1024, 512)`` will return a string of
length 40. The first 20 bytes will be the SHA-1 of the first 512 bytes
of the file, and the last 20 bytes will be the SHA-1 of the next 512
bytes.
:param str hash_algorithm:
the name of the hash algorithm to use (normally ``"sha1"`` or
``"md5"``)
:param offset:
offset into the file to begin hashing (0 means to start from the
beginning)
:type offset: int or long
:param length:
number of bytes to hash (0 means continue to the end of the file)
:type length: int or long
:param int block_size:
number of bytes to hash per result (must not be less than 256; 0
means to compute only one hash of the entire segment)
:type block_size: int
:return:
`str` of bytes representing the hash of each block, concatenated
together
:raises IOError: if the server doesn't support the "check-file"
extension, or possibly doesn't support the hash algorithm
requested
.. note:: Many (most?) servers don't support this extension yet.

Turn on/off the pipelining of write operations to this file. When
pipelining is on, paramiko won't wait for the server response after
each write operation. Instead, they're collected as they come in. At
the first non-write operation (including `.close`), all remaining
server responses are collected. This means that if there was an error
with one of your later writes, an exception might be thrown from within
`.close` instead of `.write`.
By default, files are not pipelined.
:param bool pipelined:
``True`` if pipelining should be turned on for this file; ``False``
otherwise

Pre-fetch the remaining contents of this file in anticipation of future
`.read` calls. If reading the entire file, pre-fetching can
dramatically improve the download speed by avoiding roundtrip latency.
The file's contents are incrementally buffered in a background thread.
The prefetched data is stored in a buffer until read via the `.read`
method. Once data has been read, it's removed from the buffer. The
data may be read in a random order (using `.seek`); chunks of the
buffer that haven't been read will continue to be buffered.

Read a set of blocks from the file by (offset, length). This is more
efficient than doing a series of `.seek` and `.read` calls, since the
prefetch machinery is used to retrieve all the requested blocks at
once.

file to read
