* Added initial support for reading configuration from OpenSSH-compatible
config files, when present. Both client and server configuration files are
supported, but not all config options are supported.
* Added support for the concept of only a subset of supported algorithms being
enabled by default, and for the ability to use wildcards when specifying
algorithm names. Also, OpenSSH’s syntax of prefixing the list with
‘^’, ‘+’, or ‘-‘ is supported for incrementally adjusting the list
of algorithms starting from the default set.
* Added support for specifying a preferred list of client authentication
methods, in order of preference.
* Added the ability to use AsyncSSH’s “password” argument on servers which
are using keyboard-interactive authentication to prompt for a “passcode”.
* Added support for providing separate lists of private keys and certificates,
rather than requiring them to be specifying together as a tuple.
When this new option is used, AsyncSSH will automatically associate
the private keys with their corresponding certificates if matching
certificates are present in the list.
* Added support for the “known_hosts” argument to accept a list of known host
files, rather than just a single file. Known hosts can also be specified
using the GlobalKnownHostFile and UserKnownHostFile config file options,
each of which can take multiple filenames.
* Added new “request_tty” option to provide finer grained control over whether
AsyncSSH will request a TTY when opening new sessions. The default is to
still tie this to whether a “term_type” is specified, but now that can be
overridden. Supported options of “yes”, “no”, “force”, and “auto” match
the values supported by OpenSSH.
* Added new “rdns_lookup” option to control whether the server does a reverse
DNS of client addresses to allow matching of clients based on hostname
in authorized keys and config files. When this option is disabled (the default),

* Added optional timeout parameter to SSHClientProcess.wait()
and SSHClientConnection.run() methods.
* Created subclasses for SFTPError exceptions, allowing applications
to more easily have distinct exception handling for different errors.
* Fixed an issue in SFTP parallel I/O related to handling low-level
connection failures
* Fixed an issue with SFTP file copy where a local file could sometimes
be left open if an attempt to close a remote file failed.
* Fixed an issue in the handling of boolean return values when
SSHServer.server_requested() returns a coroutine
* Fixed an issue with passing tuples to the SFTP copy functions.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-asyncssh?expand=0&rev=26
- add gss_test.patch to avoid segfault in kerberos
* Added support for U2F/FIDO2 security keys
* Added login timeout client option and limits on the length and number
of banner lines AsyncSSH will accept prior to the SSH version header.
* Improved load_keypairs() to read public key files, confirming that they
are consistent with their associated private key when they are present.
* Fixed issues in the SCP server related to handling filenames with spaces.
* Fixed an issue with resuming reading after readuntil() returns an incomplete read.
* Fixed a potential issue related to asyncio not reporting sockname/peername
when a connection is closed immediately after it is opened.
* Made SSHConnection a subclass of asyncio.Protocol to please type checkers.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-asyncssh?expand=0&rev=24
* Added support in the SSHProcess redirect mechanism to accept asyncio StreamReader and StreamWriter objects, allowing asyncio streams to be plugged in as stdin/stdout/stderr in an SSHProcess.
* Added support for key handlers in the AsyncSSH line editor to trigger signals being delivered when certain “hot keys” are hit while reading input.
* Improved cleanup of unreturned connection objects when an error occurs or the connection request is canceled or times out.
* Improved cleanup of SSH agent client objects to avoid triggering a false positive warning in Python 3.8.
* Added an example to the documentation for how to create reverse-direction SSH client and server connections.
* Made check of session objects against None explicit to avoid confusion on user-defined sessions that implement __len__ or __bool__. Thanks go to Lars-Dominik Braun for contributing this improvement!
* Some API changes which should have been included in the 2.0.0 release were missed. This release corrects that, but means that additional changes may be needed in applications moving to 2.0.1. This should hopefully be the last of such changes, but if any other issues are discovered, additional changes will be limited to 2.0.x patch releases and the API will stabilize again in the AsyncSSH 2.1 release. See the next bullet for details about the additional incompatible change.
* To be consistent with other connect and listen functions, all methods on SSHClientConnection which previously returned None on listen failures have been changed to raise an exception instead. A new ChannelListenError exception will now be raised when an SSH server returns failure on a request to open a remote listener. This change affects the following SSHClientConnection methods: create_server, create_unix_server, start_server, start_unix_server, forward_remote_port, and forward_remote_path.
* Restored the ability for SSHListener objects to be used as async context managers. This previously worked in AsyncSSH 1.x and was unintentionally broken in AsyncSSH 2.0.0.
* Added support for a number of additional functions to be called from within an “async with” statement. These functions already returned objects capable of being async context managers, but were not decorated to allow them to be directly called from within “async with”. This change applies to the top level functions create_server, listen, and listen_reverse and the SSHClientConnection methods create_server, create_unix_server, start_server, start_unix_server, forward_local_port, forward_local_path, forward_remote_port, forward_remote_path, listen_ssh, and listen_reverse_ssh,
* Fixed a couple of issues in loading OpenSSH-format certificates which were missing a trailing newline.
* Changed load_certificates() to allow multiple certificates to be loaded from a single byte string argument, making it more consistent with how load_certificates() works when reading from a file.
* Updated AsyncSSH to use the modern async/await syntax internally, now requiring Python 3.6 or later. Those wishing to use AsyncSSH on Python 3.4 or 3.5 should stick to the AsyncSSH 1.x releases.
* Changed first argument of SFTPServer constructor from an SSHServerConnection (conn) to an SSHServerChannel (chan) to allow custom SFTP server implementations to access environment variables set on the channel that SFTP is run over. Applications which subclass the SFTPServer class and implement an __init__ method will need to be updated to account for this change and pass the new argument through to the SFTPServer parent class. If the subclass has no __init__ and just uses the connection, channel, and env properties of SFTPServer to access this information, no changes should be required.
* Removed deprecated “session_encoding” and “session_errors” arguments from create_server() and listen() functions. These arguments were renamed to “encoding” and “errors” back in version 1.16.0 to be consistent with other AsyncSSH APIs.
* Removed get_environment(), get_command(), and get_subsystem() methods on SSHServerProcess class. This information was made available as “env”, “command”, and “subsystem” properties of SSHServerProcess in AsyncSSH 1.11.0.
* Removed optional loop argument from all public AsyncSSH APIs, consistent with the deprecation of this argument in the asyncio package in Python 3.8. Calls will now always use the event loop which is active at the time of the call.
* Removed support for non-async context managers on AsyncSSH connections and processes and SFTP client connections and file objects. Callers should use “async with” to invoke the async the context managers on these objects.
* Added support for SSHAgentClient being an async context manager. To be consistent with other connect calls, connect_agent() will now raise an exception when no agent is found or a connection failure occurs, rather than logging a warning and returning None. Callers should catch OSError or ChannelOpenError exceptions rather than looking for a return value of None when calling this function.
* Added set_input() and clear_input() methods on SSHLineEditorChannel to change the value of the current input line when line editing is enabled.
* Added is_closing() method to the SSHChannel, SSHProcess, SSHWriter, and SSHSubprocessTransport classes. mirroring the asyncio BaseTransport and StreamWriter methods added in Python 3.7.
* Added wait_closed() async method to the SSHWriter class, mirroring the asyncio StreamWriter method added in Python 3.7.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-asyncssh?expand=0&rev=22
* Added support for GSSAPI ECDH and Edwards DH key exchange algorithms.
* Fixed gssapi-with-mic authentication to work with GSS key exchanges, in cases where gssapi-keyex is not supported.
* Made connect_ssh and connect_reverse_ssh methods into async context managers, simplifying the syntax needed to use them to create tunneled SSH connections.
* Fixed a couple of issues with known hosts matching on tunneled SSH connections.
* Improved flexibility of key/certificate parser automatic format detection to properly recognize PEM even when other arbitrary text is present at the beginning of the file. With this change, the parser can also now handle mixing of multiple key formats in a single file.
* Added support for OpenSSL “TRUSTED” PEM certificates. For now, no enforcement is done of the additional trust restrictions, but such certificates can be loaded and used by AsyncSSH without converting them back to regular PEM format.
* Fixed some additional SFTP and SCP issues related to parsing of Windows paths with drive letters and paths with multiple colons.
* Made AsyncSSH tolerant of a client which sends multiple service requests for the “ssh-userauth” service. This is needed by the Paramiko client when it tries more than one form of authentication on a connection.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-asyncssh?expand=0&rev=20
* Improved construction of file paths in SFTP to better handle native Windows
source paths containing backslashes or drive letters.
* Improved SFTP parallel I/O for large reads and file copies to better handle
the case where a read returns less data than what was requested when not
at the end of the file, allowing AsyncSSH to get back the right result even
if the requested block size is larger than the SFTP server can handle.
* Fixed an issue where the requested SFTP block_size wasn’t used in the get,
copy, mget, and mcopy functions if it was larger than the default size of 16 KB.
* Fixed a problem where the list of client keys provided in
an SSHClientConnectionOptions object wasn’t always preserved properly across
the opening of multiple SSH connections.
* Made AsyncSSH tolerant of unexpected authentication success/failure messages
sent after authentication completes. AsyncSSH previously treated this as
a protocol error and dropped the connection, while most other SSH implementations
ignored these messages and allowed the connection to continue.
* Made AsyncSSH tolerant of SFTP status responses which are missing error message
and language tag fields, improving interoperability with servers that omit
these fields. When missing, AsyncSSH treats these fields as if they were
set to empty strings.

- drop old_openssl.patch
* Added support for “reverse direction” SSH connections, useful to support
applications like NETCONF Call Home, described in RFC 8071.
* Added support for the PyCA implementation of Chacha20-Poly1305, eliminating
the dependency on libnacl/libsodium to provide this functionality,
as long as OpenSSL 1.1.1b or later is installed.
* Restored libnacl support for Curve25519/Ed25519 on systems which have
an older version of OpenSSL that doesn’t have that support.
This fallback also applies to Chacha20-Poly1305.
* Disabled the use of RSA SHA-2 signatures when using the Pageant or Windows 10
OpenSSH agent on Windows, since neither of those support the signature
flags options to request them.
* Fixed a regression where a callable was no longer usable in the
sftp_factory argument of create_server.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-asyncssh?expand=0&rev=15
- drop 194.patch
* Added channel, connection, and env properties to SFTPServer instances,
so connection and channel information can be used to influence the
SFTP server's behavior. Previously, connection information was made
avaiable through the constructor, but channel and environment
information was not. Now, all of these are available as properties
on the SFTPServer instance without the need to explicitly store anything
in a custom constructor.
* Optimized SFTP glob matching when the glob pattern contains directory
names without glob characters in them. Thanks go to Mikhail Terekhov
for contributing this improvement!
* Added support for PurePath in a few places that were missed when this
support was originally added. Once again, thanks go to Mikhail Terehkov
for these fixes.
* Fixed bug in SFTP parallel I/O file reader where it sometimes returned
EOF prematurely. Thanks go to David G for reporting this problem and
providing a reproducible test case.
* Fixed test failures seen on Fedora Rawhide. Thanks go to Georg Sauthof
for reporting this issue and providing a test environment to help debug
it.
* Updated Ed25519/448 and Curve25519/448 tests to only run when these
algorithms are available.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-asyncssh?expand=0&rev=11
* Added support for Ed448 host/client keys and certificates and rewrote Ed25519 support to use the PyCA implementation, reducing the dependency on libnacl and libsodium to only be needed to support the chacha20-poly1305 cipher.
* Added support for PKCS#8 format Ed25519 and Ed448 private and public keys (in addition to the OpenSSH format previously supported).
* Added support for multiple delimiters in SSHReader’s readuntil() function, causing it to return data as soon as any of the specified delimiters are matched.
* Added the ability to register custom key handlers in the line editor which can modify the input line, extending the built-in editing functionality.
* Added SSHSubprocessProtocol and SSHSubprocessTransport classes to provide compatibility with asyncio.SubprocessProtocol and asyncio.SubprocessTransport. Code which is designed to call BaseEventLoop.subprocess_shell() or BaseEventLoop.subprocess_exec() can be easily adapted to work against a remote process by calling SSHClientConnection.create_subprocess().
* Added support for sending keepalive messages when the SSH connection is idle, with an option to automatically disconnect the connection if the remote system doesn’t respond to these keepalives.
* Changed AsyncSSH to ignore errors when loading unsupported key types from the default file locations.
* Changed the reuse_port option to only be available on Python releases which support it (3.4.4 and later).
* Fixed an issue where MSG_IGNORE packets could sometimes be sent between MSG_NEWKEYS and MSG_EXT_INFO, which caused some SSH implementations to fail to properly parse the MSG_EXT_INFO.
* Fixed a couple of errors in the handling of disconnects occurring prior to authentication completing.
* Renamed “session_encoding” and “session_errors” arguments in asyncssh.create_server() to “encoding” and “errors”, to match the names used for these arguments in other AsyncSSH APIs. The old names are still supported for now, but they are marked as deprecated and will be removed in a future release.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-asyncssh?expand=0&rev=7
- update to 1.15.1
* Added callback-based host validation in SSHClient, allowing callers to decide
programmatically whether to trust server host keys and certificates rather
than having to provide a list of trusted values in advance.
* Changed SSH client code to only load the default known hosts file if if exists.
Previously an error was returned if a known_hosts value wasn't specified
and the default known_hosts file didn't exist. For host validate to work in
this case, verification callbacks must be implemented or other forms
of validation such as X.509 trusted CAs or GSS-based key exchange must be used.
* Fixed known hosts validation to completely disable certificate checks when
known_hosts is set to None.
* Switched curve25519 key exchange to use the PyCA implementation
* Added get_fingerprint() method to return a fingerprint of an SSHKey.
* Added the ability to pass keyword arguments provided in the scp() command
through to asyncssh.connect() calls it makes, allowing things like custom
credentials to be specified.
* Added support for a reuse_port argument in create_server().
* Added support for "soft" EOF when line editing in enabled
* Added support for the Windows 10 OpenSSH ssh-agent.
* Reworked scoped link-local IPv6 address normalization to work better on Linux systems.
* Fixed a problem preserving directory structure in recursive scp().
* Fixed SFTP chmod tests to avoid attempting to set the sticky bit on a plain file
* Updated note in SSHClientChannel's send_signal() documentation to reflect
that OpenSSH 7.9 and later should now support processing of signal messages.
