This uses weak references, so Perl 5.6.0+ is now required. This work was funded by Kineticode, Inc. - Added a LICENSE file. 0.05 2001.05.24 - Added help ('h' or '?') command to psftp. Moved all shell functionality into Net::SFTP::Shell. - Net::SFTP::Util needed to 'use Exporter'. 0.04 2001.05.16 - Fixed bug in put method when running fsetstat command; it was trying to set the UID/GID on the remote file, which was giving a permission denied message. Should not try to set UID/GID, so had to adjust flags. - Added eg/psftp, a working SFTP shell. - Moved READ and WRITE commands into their own methods (do_read and do_write, respectively). - Changed semantics of get method. Returning the contents of the remote file is no longer connected to whether a local file is passed as an argument; it is instead based on the calling context of 'get'. Updated docs to reflect this. 0.03 2001.05.15 - Documentation for all extra classes: Attributes, Buffer, Constants, and Util. - Documentation for command methods in Net::SFTP. - Added binmode when reading/writing from local files. - Added methods for all remaining commands in SFTP protocol version 3 (eg. remove, rmdir, mkdir, realpath, etc.). - Added callbacks to get and put, eg. for status messages, etc. - Fixed typo in Net::SFTP::Buffer::get_int64 that was breaking reading 64-bit ints. 0.02 2001.05.14 - Fixed bug with SSH2 server not sending one message per packet, ie. multiple packets have to be retrieved to make up one SFTP message. This would show up as a "Message length too long" error. Thanks to Matt Good for the spot. - Fixed bug with OpenSSH and SSH2 SFTP servers where after a certain amount of bytes the connection would hang. This was a bug in Net::SSH::Perl (channel window sizes) that is fixed in version 1.13. 0.01 2001.05.13 - original version; created by h2xs 1.19
