2023-12-19 Gwyn Ciesla <gwync at protonmail dot com> - 3.4.0-1 - 3.4.0
2023-07-30 Paul Howarth <paul at city dash fan dot org> - 3.3.1-1 - Update to 3.3.1 (rhbz#2227478) - Cleaned up some very old root level files, mostly just to exercise some of our doc build and release machinery
2023-07-28 Gwyn Ciesla <gwync at protonmail dot com> - 3.3.0-1 - 3.3.0 - Add support and tests for 'Match final ..'

2023-05-27 Paul Howarth <paul at city dash fan dot org> - 3.2.0-1 - Update to 3.2.0 (rhbz#2210398) - Fixed a very sneaky bug found at the apparently rarely-traveled intersection of RSA-SHA2 keys, certificates, SSH agents, and stricter-than-OpenSSH server targets, which manifested as yet another "well, if we turn off SHA2 at one end or another, everything works again" problem, for example with version 12 of the Teleport server endpoint - The 'server-sig-algs' and 'RSA-SHA2' features added around Paramiko 2.9 or so, had the annoying side effect of not working with servers that don't support *either* of those feature sets, requiring use of 'disabled_algorithms' to forcibly disable the SHA2 algorithms on Paramiko's end (GH#1961, GH#2012 and countless others) - The *experimental* '~paramiko.transport.ServiceRequestingTransport' (noted in its own entry in this changelog) includes a fix for this issue, specifically by falling back to the same algorithm as the in-use pubkey if it's in the algorithm list (leaving the "first algorithm in said list" as an absolute final fallback) - Implement '_fields()' on '~paramiko.agent.AgentKey' so that it may be compared (via '==') with other '~paramiko.pkey.PKey' instances - Since its inception, Paramiko has (for reasons lost to time) implemented authentication as a side effect of handling affirmative replies to 'MSG_SERVICE_REQUEST' protocol messages; what this means is Paramiko makes one such request before every 'MSG_USERAUTH_REQUEST', i.e. every auth attempt (GH#23) - OpenSSH doesn't care if clients send multiple service requests, but other server implementations are often stricter in what they accept after an initial service request (due to the RFCs not being clear), which can result in odd behavior when a user doesn't authenticate successfully on the very first try (for example, when the right key for a target host is the third in one's ssh-agent) - This version of Paramiko now contains an opt-in '~paramiko.transport.Transport' subclass, '~paramiko.transport.ServiceRequestingTransport', which more-correctly implements service request handling in the Transport, and uses an auth-handler subclass internally that has been similarly adapted; users wanting to try this new experimental code path may hand this class to 'SSHClient.connect` as its 'transport_factory' kwarg - This feature is *EXPERIMENTAL* and its code may be subject to change - Minor backwards incompatible changes exist in the new code paths, most notably the removal of the (inconsistently applied and rarely used) 'event' arguments to the 'auth_xxx' methods - GSSAPI support has only been partially implemented, and is untested - Some minor backwards-*compatible* changes were made to the *existing* Transport and AuthHandler classes to facilitate the new code; for example, 'Transport._handler_table' and 'AuthHandler._client_handler_table' are now properties instead of raw attributes - Users of '~paramiko.client.SSHClient' can now configure the authentication logic Paramiko uses when connecting to servers; this functionality is intended for advanced users and higher-level libraries such as 'Fabric' (https://fabfile.org/); see '~paramiko.auth_strategy' for details (GH#387) - Fabric's co-temporal release includes a proof-of-concept use of this feature, implementing an auth flow much closer to that of the OpenSSH client (versus Paramiko's legacy behavior); it is *strongly recommended* that if this interests you, investigate replacing any direct use of 'SSHClient' with Fabric's 'Connection' - This feature is **EXPERIMENTAL**; please see its docs for details - Enhanced '~paramiko.agent.AgentKey' with new attributes, such as: - Added a 'comment' attribute (and constructor argument); 'Agent.get_keys()' now uses this kwarg to store any comment field sent over by the agent; the original version of the agent feature inexplicably did not store the comment anywhere - Agent-derived keys now attempt to instantiate a copy of the appropriate key class for access to other algorithm-specific members (e.g. key size); this is available as the '.inner_key' attribute - This functionality is now in use in Fabric's new '--list-agent-keys' feature, as well as in Paramiko's debug logging - '~paramiko.pkey.PKey' now offers convenience "meta-constructors", static methods that simplify the process of instantiating the correct subclass for a given key input - For example, 'PKey.from_path' can load a file path without knowing *a priori* what type of key it is (thanks to some handy methods within our cryptography dependency); going forwards, we expect this to be the primary method of loading keys by user code that runs on "human time" (i.e. where some minor efficiencies are worth the convenience) - In addition, 'PKey.from_type_string' now exists, and is being used in some internals to load ssh-agent keys - As part of these changes, '~paramiko.pkey.PKey' and friends grew a '~paramiko.pkey.PKey.identifiers' classmethod; this is inspired by the '~paramiko.ecdsakey.ECDSAKey.supported_key_format_identifiers' classmethod (which now refers to the new method); this also includes adding a '.name' attribute to most key classes (which will eventually replace '.get_name()') - '~paramiko.pkey.PKey' grew a new '.algorithm_name' property that displays the key algorithm; this is typically derived from the value of '~paramiko.pkey.PKey.get_name'; for example, ED25519 keys have a 'get_name' of 'ssh-ed25519' (the SSH protocol key type field value), and now have a 'algorithm_name' of 'ED25519' - '~paramiko.pkey.PKey' grew a new '.fingerprint' property that emits a fingerprint string matching the SHA256+Base64 values printed by various OpenSSH tooling (e.g. 'ssh-add -l', 'ssh -v'); this is intended to help troubleshoot Paramiko-vs-OpenSSH behavior and will eventually replace the venerable 'get_fingerprint' method - '~paramiko.agent.AgentKey' had a dangling Python 3 incompatible '__str__' method returning bytes; this method has been removed, allowing the superclass' ('~paramiko.pkey.PKey') method to run instead
2023-03-12 Paul Howarth <paul at city dash fan dot org> - 3.1.0-1 - Update to 3.1.0 (rhbz#2177436) - Add an explicit 'channel_timeout' keyword argument to 'paramiko.client.SSHClient.connect', allowing users to configure the previously-hardcoded default value of 3600 seconds (GH#2009, GH#2013, and others) - Accept single tabs as field separators (in addition to single spaces) in 'paramiko.hostkeys.HostKeyEntry.from_line' for parity with OpenSSH's KnownHosts parser (GH#2173) - Apply 'codespell' to the codebase, which found a lot of very old minor spelling mistakes in docstrings; also, modernize many instances of '*largs' vs. '*args' and '**kwarg' vs. '**kwargs' (GH#2178)
2023-01-22 Paul Howarth <paul at city dash fan dot org> - 3.0.0-1 - Update to 3.0.0 (rhbz#2162914) - Remove some unnecessary '__repr__' calls when handling bytes-vs-str conversions; this was apparently doing a lot of unintentional data processing, which adds up in some use cases, such as SFTP transfers, which may now be significantly faster (GH#2110) - Streamline some redundant (and costly) byte conversion calls in the packetizer and the core SFTP module; this should lead to some SFTP speedups at the very least (GH#2165) - 'paramiko.util.retry_on_signal' (and any internal uses of same, and also any internal retries of 'EINTR' on e.g. socket operations) has been removed; as of Python 3.5, per PEP 475 (https://peps.python.org/pep-0475/), this functionality (and retrying 'EINTR' generally) is now part of the standard library Note: This change is backwards incompatible if you were explicitly importing/using this particular function; the observable behavior otherwise should not be changing - '~paramiko.config.SSHConfig' used to straight-up delete the 'proxycommand' key from config lookup results when the source config said 'ProxyCommand none'; this has been altered to preserve the key and give it the Python value 'None', thus making the Python representation more in line with the source config file Note: This change is backwards incompatible if you were relying on the old (1.x, 2.x) behavior for some reason (e.g. assuming all 'proxycommand' values were valid subcommand strings) - The behavior of private key classes' (i.e. anything inheriting from '~paramiko.pkey.PKey') private key writing methods used to perform a manual, extra 'chmod' call after writing; this hasn't been strictly necessary since the mid 2.x release line (when key writing started giving the 'mode' argument to 'os.open'), and has now been removed entirely; this should only be observable if you were mocking Paramiko's system calls during your own testing, or similar - 'PKey.__cmp__' has been removed - ordering-oriented comparison of key files is unlikely to have ever made sense (the old implementation attempted to order by the hashes of the key material) and so we have not bothered setting up '__lt__' and friends at this time; the class continues to have its original '__eq__' untouched Note: This change is backwards incompatible if you were actually trying to sort public key objects (directly or indirectly); please file bug reports detailing your use case if you have some intractable need for this behavior, and we'll consider adding back the necessary Python 3 magic methods so that it works as before - A handful of lower-level classes (notably 'paramiko.message.Message' and 'paramiko.pkey.PKey') previously returned 'bytes' objects from their implementation of '__str__', even under Python 3; and there was never any '__bytes__' method; these issues have been fixed by renaming '__str__' to '__bytes__' and relying on Python's default "stringification returns the output of '__repr__'" behavior re: any real attempts to 'str()' such objects - 'paramiko.common.asbytes' has been moved to 'paramiko.util.asbytes' Note: This change is backwards incompatible if you were directly using this function (which is unlikely) - Remove the now irrelevant 'paramiko.py3compat' module Note: This change is backwards incompatible - such references should be search-and-replaced with their modern Python 3.6+ equivalents; in some cases, still-useful methods or values have been moved to 'paramiko.util' (most) or 'paramiko.common' ('byte_*') - Drop support for Python versions less than 3.6, including Python 2; so long and thanks for all the fish! Our packaging metadata has been updated to include 'python_requires', so this should not cause breakage unless you're on an old installation method that can't read this metadata Note: As part of this change, our dependencies have been updated; e.g. we now require Cryptography>=3.3, up from 2.5
2023-01-20 Fedora Release Engineering <releng at fedoraproject dot org> - 2.12.0-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_38_Mass_Rebuild
2022-11-06 Paul Howarth <paul at city dash fan dot org> - 2.12.0-1 - Update to 2.12.0 (rhbz#2140281) - Add a 'transport_factory' kwarg to 'SSHClient.connect' for advanced users to gain more control over early Transport setup and manipulation (GH#2054, GH#2125) - Update '~paramiko.client.SSHClient' so it explicitly closes its wrapped socket object upon encountering socket errors at connection time; this should help somewhat with certain classes of memory leaks, resource warnings, and/or errors (though we hasten to remind everyone that Client and Transport have their own '.close()' methods for use in non-error situations!) (GH#1822) - Raise '~paramiko.ssh_exception.SSHException' explicitly when blank private key data is loaded, instead of the natural result of 'IndexError'; this should help more bits of Paramiko or Paramiko-adjacent codebases to correctly handle this class of error (GH#1599, GH#1637) - Use SPDX-format license tag
