=========
Changelog
=========
* :bug:`373 major` Attempt to fix a handful of issues (such as :issue:`354`)
related to infinite loops and threading deadlocks. Thanks to Olle Lundberg as
well as a handful of community members who provided advice & feedback via
IRC.
* :support:`374` (also :issue:`375`) Old code cleanup courtesy of Olle
Lundberg.
* :support:`377` Factor `~paramiko.channel.Channel` openness sanity check into
a decorator. Thanks to Olle Lundberg for original patch.
* :bug:`298 major` Don't perform point validation on ECDSA keys in
``known_hosts`` files, since a) this can cause significant slowdown when such
keys exist, and b) ``known_hosts`` files are implicitly trustworthy. Thanks
to Kieran Spear for catch & patch.
.. note::
This change bumps up the version requirement for the ``ecdsa`` library to
``0.11``.
* :bug:`234 major` Lower logging levels for a few overly-noisy log messages
about secure channels. Thanks to David Pursehouse for noticing & contributing
the fix.
* :feature:`218` Add support for ECDSA private keys on the client side. Thanks
to ``@aszlig`` for the patch.
* :bug:`335 major` Fix ECDSA key generation (generation of brand new ECDSA keys
was broken previously). Thanks to ``@solarw`` for catch & patch.
* :feature:`184` Support quoted values in SSH config file parsing. Credit to
Yan Kalchevskiy.
* :feature:`131` Add a `~paramiko.sftp_client.SFTPClient.listdir_iter` method
to `~paramiko.sftp_client.SFTPClient` allowing for more efficient,
async/generator based file listings. Thanks to John Begeman.
* :support:`378 backported` Minor code cleanup in the SSH config module
courtesy of Olle Lundberg.
* :support:`249` Consolidate version information into one spot. Thanks to Gabi
Davar for the reminder.
* :release:`1.14.1 <2014-08-25>`
* :release:`1.13.2 <2014-08-25>`
* :bug:`376` Be less aggressive about expanding variables in ``ssh_config``
files, which results in a speedup of SSH config parsing. Credit to Olle
Lundberg.
* :support:`324 backported` A bevvy of documentation typo fixes, courtesy of Roy
Wellington.
* :bug:`312` `paramiko.transport.Transport` had a bug in its ``__repr__`` which
surfaces during errors encountered within its ``__init__``, causing
problematic tracebacks in such situations. Thanks to Simon Percivall for
catch & patch.
* :bug:`272` Fix a bug where ``known_hosts`` parsing hashed the input hostname
as well as the hostnames from the ``known_hosts`` file, on every comparison.
Thanks to ``@sigmunau`` for final patch and ``@ostacey`` for the original
report.
* :bug:`239` Add Windows-style CRLF support to SSH config file parsing. Props
to Christopher Swenson.
* :support:`229 backported` Fix a couple of incorrectly-copied docstrings' ``..
versionadded::`` RST directives. Thanks to Aarni Koskela for the catch.
* :support:`169 backported` Minor refactor of
`paramiko.sftp_client.SFTPClient.put` thanks to Abhinav Upadhyay.
* :bug:`285` (also :issue:`352`) Update our Python 3 ``b()`` compatibility shim
to handle ``buffer`` objects correctly; this fixes a frequently reported
issue affecting many users, including users of the ``bzr`` software suite.
Thanks to ``@basictheprogram`` for the initial report, Jelmer Vernooij for
the fix and Andrew Starr-Bochicchio & Jeremy T. Bouse (among others) for
discussion & feedback.
* :support:`371` Add Travis support & docs update for Python 3.4. Thanks to
Olle Lundberg.
* :release:`1.14.0 <2014-05-07>`
* :release:`1.13.1 <2014-05-07>`
* :release:`1.12.4 <2014-05-07>`
* :release:`1.11.6 <2014-05-07>`
* :bug:`-` `paramiko.file.BufferedFile.read` incorrectly returned text strings
after the Python 3 migration, despite bytes being more appropriate for file
contents (which may be binary or of an unknown encoding.) This has been
addressed.
.. note::
`paramiko.file.BufferedFile.readline` continues to return strings, not
bytes, as "lines" only make sense for textual data. It assumes UTF-8 by
default.
This should fix `this issue raised on the Obnam mailing list
<http://comments.gmane.org/gmane.comp.sysutils.backup.obnam/252>`_. Thanks
to Antoine Brenner for the patch.
* :bug:`-` Added self.args for exception classes. Used for unpickling. Related
to (`Fabric #986 <https://github.com/fabric/fabric/issues/986>`_, `Fabric
#714 <https://github.com/fabric/fabric/issues/714>`_). Thanks to Alex
Plugaru.
* :bug:`-` Fix logging error in sftp_client for filenames containing the '%'
character. Thanks to Antoine Brenner.
* :bug:`308` Fix regression in dsskey.py that caused sporadic signature
verification failures. Thanks to Chris Rose.
* :support:`299` Use deterministic signatures for ECDSA keys for improved
security. Thanks to Alex Gaynor.
* :support:`297` Replace PyCrypto's ``Random`` with `os.urandom` for improved
speed and security. Thanks again to Alex.
* :support:`295` Swap out a bunch of PyCrypto hash functions with use of
`hashlib`. Thanks to Alex Gaynor.
* :support:`290` (also :issue:`292`) Add support for building universal
(Python 2+3 compatible) wheel files during the release process. Courtesy of
Alex Gaynor.
* :support:`284` Add Python language trove identifiers to ``setup.py``. Thanks
to Alex Gaynor for catch & patch.
* :bug:`235` Improve string type testing in a handful of spots (e.g. ``s/if
type(x) is str/if isinstance(x, basestring)/g``.) Thanks to ``@ksamuel`` for
the report.
* :release:`1.13.0 <2014-03-13>`
* :release:`1.12.3 <2014-03-13>`
* :release:`1.11.5 <2014-03-13>`
* :release:`1.10.7 <2014-03-13>`
* :feature:`16` **Python 3 support!** Our test suite passes under Python 3, and
it (& Fabric's test suite) continues to pass under Python 2. **Python 2.5 is
no longer supported with this change!**
The merged code was built on many contributors' efforts, both code &
feedback. In no particular order, we thank Daniel Goertzen, Ivan Kolodyazhny,
Tomi Pieviläinen, Jason R. Coombs, Jan N. Schulze, ``@Lazik``, Dorian Pula,
Scott Maxwell, Tshepang Lekhonkhobe, Aaron Meurer, and Dave Halter.

API docs website to replace the old Epydoc one. Thanks to Olle Lundberg for
the initial conversion work.
* :bug:`-` Use constant-time hash comparison operations where possible, to
protect against `timing-based attacks
<http://codahale.com/a-lesson-in-timing-attacks/>`_. Thanks to Alex Gaynor
for the patch.
* :release:`1.12.2 <2014-02-14>`
* :release:`1.11.4 <2014-02-14>`
* :release:`1.10.6 <2014-02-14>`
* :feature:`58` Allow client code to access the stored SSH server banner via
`Transport.get_banner <paramiko.transport.Transport.get_banner>`. Thanks to
``@Jhoanor`` for the patch.
* :bug:`252` (`Fabric #1020 <https://github.com/fabric/fabric/issues/1020>`_)
Enhanced the implementation of ``ProxyCommand`` to avoid a deadlock/hang
condition that frequently occurs at ``Transport`` shutdown time. Thanks to
Mateusz Kobos, Matthijs van der Vleuten and Guillaume Zitta for the original
reports and to Marius Gedminas for helping test nontrivial use cases.
* :bug:`268` Fix some missed renames of ``ProxyCommand`` related error classes.
Thanks to Marius Gedminas for catch & patch.
* :bug:`34` (PR :issue:`35`) Fix SFTP prefetching incompatibility with some
SFTP servers regarding request/response ordering. Thanks to Richard
Kettlewell.
* :bug:`193` (and its attentant PRs :issue:`230` & :issue:`253`) Fix SSH agent
problems present on Windows. Thanks to David Hobbs for initial report and to
Aarni Koskela & Olle Lundberg for the patches.
* :release:`1.12.1 <2014-01-08>`
* :release:`1.11.3 <2014-01-08>`
* :release:`1.10.5 <2014-01-08>`
* :bug:`225 (1.12+)` Note ecdsa requirement in README. Thanks to Amaury
Rodriguez for the catch.
* :bug:`176` Fix AttributeError bugs in known_hosts file (re)loading. Thanks
to Nathan Scowcroft for the patch & Martin Blumenstingl for the initial test
case.
* :release:`1.12.0 <2013-09-27>`
* :release:`1.11.2 <2013-09-27>`
* :release:`1.10.4 <2013-09-27>`
* :feature:`152` Add tentative support for ECDSA keys. **This adds the ecdsa
module as a new dependency of Paramiko.** The module is available at
`warner/python-ecdsa on Github <https://github.com/warner/python-ecdsa>`_ and
`ecdsa on PyPI <https://pypi.python.org/pypi/ecdsa>`_.
* Note that you might still run into problems with key negotiation --
Paramiko picks the first key that the server offers, which might not be
what you have in your known_hosts file.
* Mega thanks to Ethan Glasser-Camp for the patch.
* :feature:`136` Add server-side support for the SSH protocol's 'env' command.
Thanks to Benjamin Pollack for the patch.

a non-default AddressFamily set. Thanks to Ed Marshall & Tomaz Muraus for
catch & patch.
* :bug:`200` Fix an exception-causing typo in ``demo_simple.py``. Thanks to Alex
Buchanan for catch & Dave Foster for patch.
* :bug:`199` Typo fix in the license header cross-project. Thanks to Armin
Ronacher for catch & patch.
* :release:`1.11.1 <2013-09-20>`
* :release:`1.10.3 <2013-09-20>`

* :bug:`36` Fix the port-forwarding demo to avoid file descriptor errors.
Thanks to Jonathan Halcrow for catch & patch.
* :bug:`168` Update config handling to properly handle multiple 'localforward'
and 'remoteforward' keys. Thanks to Emre Yılmaz for the patch.
* :release:`1.11.0 <2013-07-26>`
* :release:`1.10.2 <2013-07-26>`
* :bug:`98 major` On Windows, when interacting with the PuTTY PAgeant, Paramiko
now creates the shared memory map with explicit Security Attributes of the
user, which is the same technique employed by the canonical PuTTY library to
avoid permissions issues when Paramiko is running under a different UAC
context than the PuTTY Ageant process. Thanks to Jason R. Coombs for the
patch.
* :support:`100` Remove use of PyWin32 in ``win_pageant`` module. Module was
already dependent on ctypes for constructing appropriate structures and had
ctypes implementations of all functionality. Thanks to Jason R. Coombs for
the patch.
* :bug:`87 major` Ensure updates to ``known_hosts`` files account for any
updates to said files after Paramiko initially read them. (Includes related
fix to guard against duplicate entries during subsequent ``known_hosts``
loads.) Thanks to ``@sunweaver`` for the contribution.
* :bug:`153` (also :issue:`67`) Warn on parse failure when reading known_hosts
file. Thanks to ``@glasserc`` for patch.

catch & patch.
* :release:`1.10.1 <2013-04-05>`
* :bug:`142` (`Fabric #811 <https://github.com/fabric/fabric/issues/811>`_)
SFTP put of empty file will still return the attributes of the put file.
Thanks to Jason R. Coombs for the patch.
* :bug:`154` (`Fabric #876 <https://github.com/fabric/fabric/issues/876>`_)
Forwarded SSH agent connections left stale local pipes lying around, which
could cause local (and sometimes remote or network) resource starvation when
running many agent-using remote commands. Thanks to Kevin Tegtmeier for catch
& patch.
* :release:`1.10.0 <2013-03-01>`
* :feature:`66` Batch SFTP writes to help speed up file transfers. Thanks to
Olle Lundberg for the patch.
* :bug:`133 major` Fix handling of window-change events to be on-spec and not
attempt to wait for a response from the remote sshd; this fixes problems with
less common targets such as some Cisco devices. Thanks to Phillip Heller for
catch & patch.
* :feature:`93` Overhaul SSH config parsing to be in line with ``man
ssh_config`` (& the behavior of ``ssh`` itself), including addition of parameter
expansion within config values. Thanks to Olle Lundberg for the patch.
* :feature:`110` Honor SSH config ``AddressFamily`` setting when looking up
local host's FQDN. Thanks to John Hensley for the patch.
* :feature:`128` Defer FQDN resolution until needed, when parsing SSH config
files. Thanks to Parantapa Bhattacharya for catch & patch.
* :bug:`102 major` Forego random padding for packets when running under
``*-ctr`` ciphers. This corrects some slowdowns on platforms where random
byte generation is inefficient (e.g. Windows). Thanks to ``@warthog618`` for
catch & patch, and Michael van der Kolff for code/technique review.
* :feature:`127` Turn ``SFTPFile`` into a context manager. Thanks to Michael
Williamson for the patch.
* :feature:`116` Limit ``Message.get_bytes`` to an upper bound of 1MB to protect
against potential DoS vectors. Thanks to ``@mvschaik`` for catch & patch.
* :feature:`115` Add convenience ``get_pty`` kwarg to ``Client.exec_command`` so
users not manually controlling a channel object can still toggle PTY
creation. Thanks to Michael van der Kolff for the patch.
* :feature:`71` Add ``SFTPClient.putfo`` and ``.getfo`` methods to allow direct
uploading/downloading of file-like objects. Thanks to Eric Buehl for the
patch.
* :feature:`113` Add ``timeout`` parameter to ``SSHClient.exec_command`` for
easier setting of the command's internal channel object's timeout. Thanks to
Cernov Vladimir for the patch.
* :support:`94` Remove duplication of SSH port constant. Thanks to Olle
Lundberg for the catch.
* :feature:`80` Expose the internal "is closed" property of the file transfer
class ``BufferedFile`` as ``.closed``, better conforming to Python's file
interface. Thanks to ``@smunaut`` and James Hiscock for catch & patch.
