Releases
|
|
========
|
|
|
|
v1.9.0 (6th Nov 2012)
|
|
---------------------
|
|
|
|
* #97 (with a little #93): Improve config parsing of `ProxyCommand` directives
|
|
and provide a wrapper class to allow subprocess-driven proxy commands to be
|
|
used as `sock=` arguments for `SSHClient.connect`.
|
|
* #77: Allow `SSHClient.connect()` to take an explicit `sock` parameter
|
|
overriding creation of an internal, implicit socket object.
|
|
* Thanks in no particular order to Erwin Bolwidt, Oskari Saarenmaa, Steven
|
|
Noonan, Vladimir Lazarenko, Lincoln de Sousa, Valentino Volonghi, Olle
|
|
Lundberg, and Github user `@acrish` for the various and sundry patches
|
|
leading to the above changes.
|
|
|
|
v1.8.1 (6th Nov 2012)
|
|
---------------------
|
|
|
|
* #90: Ensure that callbacks handed to `SFTPClient.get()` always fire at least
|
|
once, even for zero-length files downloaded. Thanks to Github user `@enB` for
|
|
the catch.
|
|
* #85: Paramiko's test suite overrides
|
|
`unittest.TestCase.assertTrue/assertFalse` to provide these modern assertions
|
|
to Python 2.2/2.3, which lacked them. However on newer Pythons such as 2.7,
|
|
this now causes deprecation warnings. The overrides have been patched to only
|
|
execute when necessary. Thanks to `@Arfrever` for catch & patch.
|
|
|
|
|
|
v1.8.0 (3rd Oct 2012)
|
|
---------------------
|
|
|
|
* #17 ('ssh' 28): Fix spurious `NoneType has no attribute 'error'` and similar
|
|
exceptions that crop up on interpreter exit.
|
|
* 'ssh' 32: Raise a more useful error explaining which `known_hosts` key line was
|
|
problematic, when encountering `binascii` issues decoding known host keys.
|
|
Thanks to `@thomasvs` for catch & patch.
|
|
* 'ssh' 33: Bring `ssh_config` parsing more in line with OpenSSH spec, re: order of
|
|
setting overrides by `Host` specifiers. Specifically, the overrides now go by
|
|
file order instead of automatically sorting by `Host` value length. In
|
|
addition, the first value found per config key (e.g. `Port`, `User` etc)
|
|
wins, instead of the last. Thanks to Jan Brauer for the contribution.
|
|
* 'ssh' 36: Support new server two-factor authentication option
|
|
(`RequiredAuthentications2`), at least re: combining key-based & password
|
|
auth. Thanks to Github user `bninja`.
|
|
* 'ssh' 11: When raising an exception for hosts not listed in
|
|
`known_hosts` (when `RejectPolicy` is in effect) the exception message was
|
|
confusing/vague. This has been improved somewhat. Thanks to Cal Leeming for
|
|
highlighting the issue.
|
|
* 'ssh' 40: Fixed up & expanded EINTR signal handling. Thanks to Douglas Turk.
|
|
* 'ssh' 15: Implemented parameter substitution in SSHConfig, matching the
|
|
implementation of `ssh_config(5)`. Thanks to Olle Lundberg for the patch.
|
|
* 'ssh' 24: Switch some internal type checking to use `isinstance` to help prevent
|
|
problems with client libraries using subclasses of builtin types. Thanks to
|
|
Alex Morega for the patch.
|
|
* Fabric #562: Agent forwarding would error out (with `Authentication response
|
|
too long`) or freeze, when more than one remote connection to the local agent
|
|
was active at the same time. This has been fixed. Thanks to Steven McDonald
|
|
for assisting in troubleshooting/patching, and to GitHub user `@lynxis` for
|
|
providing the final version of the patch.
|
|
* 'ssh' 5: Moved a `fcntl` import closer to where it's used to help avoid
|
|
`ImportError` problems on Windows platforms. Thanks to Jason Coombs for the
|
|
catch + suggested fix.
|
|
* 'ssh' 4: Updated implementation of WinPageant integration to work on 64-bit
|
|
Windows. Thanks again to Jason Coombs for the patch.
|
|
* Added an IO loop sleep() call to avoid needless CPU usage when agent
|
|
forwarding is in use.
|
|
* Handful of internal tweaks to version number storage.
|
|
* Updated `setup.py` with `==dev` install URL for `pip` users.
|
|
* Updated `setup.py` to account for packaging problems in PyCrypto 2.4.0
|
|
* Added an extra `atfork()` call to help prevent spurious RNG errors when
|
|
running under high parallel (multiprocess) load.
|
|
* Merge PR #28: https://github.com/paramiko/paramiko/pull/28 which adds a
|
|
ssh-keygen like demo module. (Sofian Brabez)
|
|
|
|

* some more unit tests
|
|
|
|
v1.3 (marowak) 09apr05

----------------------
|
|
* fixed a bug where packets larger than about 12KB would cause the session
|
|
to die on all platforms except osx
|
|
* added a potential workaround for windows to let Channel.fileno() (and

manipulating the exit status of a command from either client or server
|
|
mode

|
* moved check_global_request into ServerInterface, where it should've been
|
|
all along (oops)
|
|
* SFTPHandle's default implementations are fleshed out more
|
|

|
Transport

|
|
|
|
v0.9 (ivysaur) 22oct04
|
|
----------------------
|

|
|
* Transport added global_request() [client] and check_global_request()

|
|
tuple of strings

|
