fix from john arbash-meinel for the stub sftp server's default open mode
|
|
sadly, revert the append optimization -- it breaks for openssh
|
|
fix __setitem__ to do the right thing
|
|
when a file is open for append, don't stat to get the file position unless the user asks for it explicitly
|
|
add 'flags' param to SFTPHandle and make the default impl avoid calling tell() when in append mode; add proper append-mode support to stub_sftp
|
|
add a unit test to verify that all the paramiko symbols are exported correctly
|
|
use hexlify in tests
|
|
allow prefetch + readv to occur at the same time (even though it will be really inefficient). instead of a moving pointer, use the prefetched buffers as an indication of what we've downloaded so far. break up large readv requests into the max packet size. add 2 more unit tests to test this stuff.
|
|
attempt to implement support for kex-gex 'old' packet type, which is apparently used by putty (this would only affect paramiko in server mode)
|
|
add PKey.from_private_key to read from a file object
|
|
add PKey.write_private_key to write a private key into a file object, and add tests for it
|
|
fix new cygwin test failures reported by alexander
|
|
new parent exception for all auth failures, and new specific exception for bad host key
|
|
pulled out openssh config parsing into its own class
|
|
add unit tests for SSHClient, and fix a few bugs that uncovered
|
|
channel operations raise an exception on error now instead of returning a bool
|
|
if open_channel fails, it now raises ChannelException. added a unit test for that too. renegotiate_keys will also raise an exception now instead of returning a bool.
|
|
make a slightly different exception for the expected mode on cygwin (why would they add support for some but not all of the unix mode bits? very odd)
|
|
readv should just yield results as it gets them (suggestion from robertc)
|
|
2 more unit test bugs found by alexander (can't change atime on win32)
|
|
tweak a test that relied too much on timing
|
|
fix a bug where prefetch() at EOF would throw an exception, and add a unit test
|
|
add a test that feed/read can happen piecemeal
|
|
factor out BufferedPipe into its own class
|
|
assertTrue doesn't exist in py23
|
|
some fixes for win32: potential fix for lockup during failed tests; don't try chmod/chown or symlinks; fix canonicalize to convert dos-style path separators to '/'; open local files in binary mode; close a file before erasing it
|
|
roll in some changes from bzr that may be necessary to get stub_sftp to work on windows
|
|
fix exception-catching error found by alexander belchenko
|
|
document readv, fix thinko, and add a readv unit test
|
|
add test to verify that 'for x in hostkeys' works
|
|
move sftp big-file tests into a separate class and add one that does a prefetch, then seeks in random order
|
|
improve HostKeys so that it more correctly emulates a dict, and add a unit test to verify that
|
|
add SFTPClient.truncate. add chmod, chown, utime, and truncate to SFTPFile. and of course tests.
|
|
add HostKeys, a helper for reading/parsing openssh known_hosts files, including hashed-host support
|
|
experimental util functions for parsing/getting openssh host config, and unit tests (turned out to be pretty easy)
|
|
add unit test for compression
|
|
new unit test for doing a bunch of prefetches at once
|
|
dumb test to verify utf8 encoding
|
|
add 'x' flag to open to allow O_EXCL behavior
|
|
don't attempt to start a rekey negotiation from within send_message -- always do it from the feeder thread. this prevents a situation where more than one thread may decide spontaneously to rekey, sending multiple kexinit messages, which confuses the hell out of the remote host :) also, do some locking around the clear-to-send event, to avoid a race when we first go into rekeying. add some tests for these things too
|
|
add SFTPFile.prefetch() to allow pre-fetching a file that will be downloaded in full -- quick testing showed this could speed up downloads 3x or more
|
|
add server-side support for keyboard-interactive auth, and a couple of unit tests
|
|
add file pipelining for writes
|
|
dumb tiny tweaks
|
|
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
|
|
bulletproof the select test in test_transport more
|
|
add SFTPClient.put and SFTPClient.get, and make sftp file objects auto-close on del
|
|
add the concept of a cwd to SFTPClient, and add a unit test for it
|
|
cool optimization from john rochester: use cStringIO in Message (and also fix some unit test bugs revealed by the change)
|
|
2 keys needed for unit tests
|
