add SFTPFile.check and server support (and test) -- it's an sftp extension that allows a client to retrieve the hash of part or all of a file without downloading it. we're probably the only ones who implement it yet
split out Packetizer, fix banner detection bug, new unit test
split out a chunk of BaseTransport into a Packetizer class, which handles
the in/out packet data, ciphers, etc. it didn't make the code any smaller
(transport.py is still close to 1500 lines, which is awful) but it did split
out a coherent chunk of functionality into a discrete unit.
in the process, fixed a bug that alain spineux pointed out: the banner
check was too forgiving and would block forever waiting for an SSH banner.
now it waits 5 seconds for the first line, and 2 seconds for each subsequent
line, before giving up.
added a unit test to test keepalive, since i wasn't sure that was still
working after pulling out Packetizer.
change SubsystemHandler/SFTPServerInterface API
change the API of SubsystemHandler to accept a reference to the
ServerInstance object during construction. this will break all code
that currently creates subsystem handlers (like sftp servers) -- sorry!
lots of little doc fixups (mostly indenting).
add thread ids to logs
add a logging filter that reports the thread-id of the logger, and use
that for all paramiko logging. since thread-local stuff didn't appear
until python 2.4, i hacked up my own little version to assign incrementing
numbers to threads as they log.
misc logging fixes
change the level of some log messages so interesting stuff gets logged at
info instead of debug. fix an oops where channels defaulted to being in
ultra debug mode, and make this mode depend on a new Transport method:
"set_hexdump".
more flexible logging
some tweaks to make channels etc follow the logger setting of their parent
transport, so that setting the log channel for a paramiko transport will
cause all sub-logging to branch out from that channel.
also, close all open file handles when the sftp server ends.
cleanup & docs in sftp
add some more docs to SFTPHandle, and give a default implementation for
close() that's usually right. add a flush() to the default implementation
of write(). document that symlink's args in the sftp protocol are out of
order (the spec is wrong).
symlink, readlink
add support for symlink command, and finish support for readlink. (i guess
i started readlink a while ago but forgot to add the right method to the
SFTPServerInterface class.)
sftp server support!
finally check in sftp_handle (file handle abstraction), sftp_si (server
interface), and sftp_server (server implementation) -- all of which make
a roughly 90% implementation of server-side sftp.
