This can be used to verify a successful upload or download, or for various rsync-like operations. The file is hashed from C{offset}, for C{length} bytes. If C{length} is 0, the remainder of the file is hashed. Thus, if both C{offset} and C{length} are zero, the entire file is hashed. Normally, C{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 C{block_size} is given, each chunk of the file (from C{offset} to C{offset + length}) of C{block_size} bytes is computed as a separate hash. The hash results are all concatenated and returned as a single string. For example, C{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 hash_algorithm: the name of the hash algorithm to use (normally C{"sha1"} or C{"md5"}) @type hash_algorithm: str @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 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: string of bytes representing the hash of each block, concatenated together @rtype: str @note: Many (most?) servers don't support this extension yet. @raise IOError: if the server doesn't support the "check-file" extension, or possibly doesn't support the hash algorithm requested @since: 1.4 s check-file(RR!t CMD_EXTENDEDRR@RDt get_remainder( Rthash_algorithmR-tlengtht block_sizeRFRGtexttalgRE((sQC:\Documents and Settings\red08xgu\Desktop\python_webupdate\paramiko\sftp_file.pytcheck's /$   cCs ||_dS(sì 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.

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 L{read} method. Once data has been read, it's removed from the buffer.
