yeah! figured out the last things that were causing GC cycles and got rid of them: Channels, Transports, SFTPClients, and SFTPFiles can all have __del__ methods now, which auto-close themselves :)
try to handle utf8 paths in a sane way in SFTPClient: assume incoming strings are already utf8, and encode incoming unicodes -- for return values, use str if an ascii encoding will work, otherwise return a unicode
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.
make SFTPClient.file an alias for SFTPClient.open.
clean up docs a little, and make 'file' an alias for 'open'.
this is how python is heading in general.
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.
added listdir_attr()
add SFTPClient.listdir_attr() to fetch a list of files & their attributes,
instead of just their filenames. artur piwko would find this useful.
add sftp.normalize
kevin c. dorff pointed out that it would be nice to expose a way to
determine the server's "current working directory", so this new method
(normalize) directly maps to REALPATH.
add sftp_client.py
i retardedly forgot to import this file a few days ago: it's the split-out
client mode for sftp. it now also has some changes to adapt it to the
improved SFTPAttributes object API.
