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).
tweak sftp_file write behavior on large blocks of data
BufferedFile.write() wasn't correctly dealing with the possibility that the
underlying write might not write the entire data block at once (even though
the docs said it would). now that it's working, make sftp_file take
advantage of it in order to chop up blocks larger than 32kB (the max allowed
on sftp) and add a unit test for it.
loopback sftp test
add ability to turn off more tests, and a secret (for now) -X option to do
the sftp tests via loopback socket. added another symlink sftp test to see
what happens with absolute symlinks.
clean up authentication
add new exception "BadAuthenticationType", which is raised when auth fails
because your auth type (password or public-key) isn't valid on the server.
used this as an excuse to clean up auth_password and auth_publickey so their
'event' arg is optional, and if missing, they block until auth is finished,
raising an exception on error.
also, don't close the session on failed auth -- the server may let you try
again.
added some test cases for failed auth.
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.)
add key exchange tests + 1 more sftp test
add test suite for key-exchange protocols, since i apparently broke the
"gex" protocol recently and never noticed. also add an sftp unit test for
mkdir/rmdir.
fix test.py to use options instead of env vars, sftp tests default off
fix up the test framework so that the sftp unit tests aren't always run (you
have to ask for them explicitly) and they take their configuration from
command-line options. they still require a remote server.
add Message.rewind()
add rewind() method to Message, which just resets the pointer so you can
start reading from the beginning again. this is useful for some tests.
unit tests for Message
spanking new unit tests for Message. i'm trying to fix the embarrassment
of having so little of paramiko testable. next up is Transport!
more unit tests
add a unit test for sending a large (1MB) file with line buffering but no
linefeeds (this triggered several bugs and inefficiencies), and another test
to verify that the write buffer is flushed on seek.
add an sftp unit test for making 100 files
create 100 files on the remote server, set their mode with chmod, then verify
that they're all there and contain the right data. valeriy is reporting that
sometimes he's getting stuck after 20 and though i'm not seeing it, i want to
add a test to try to pin it down.
support py22, more or less
add roger binns' patches for supporting python 2.2. i hedged a bit on the
logging stuff and just added some trickery to let logging be stubbed out for
python 2.2. this changed a lot of import statements but i managed to avoid
hacking at any of the existing logging.
socket timeouts are required for the threads to notice when they've been
deactivated. worked around it by using the 'select' module on py22.
also fixed the sftp unit tests to cope with a password-protected private key.
add unit tests
add unit tests for BufferedFile and SFTP (it's a start). remove the demo sftp
client because it was 99% copied from the other demos, which makes it kinda
confusing. the unit tests are a much better example.
