AsyncSSH 1.13.0 released!

[Ron Frederick]

AsyncSSH version 1.13.0 is now available on Github and PyPI, with minor bug fixes and enhancements. Here’s a list of changes since 1.12.2:

* Added support for dynamic port forwarding via SOCKS, where AsyncSSH
will open a listener which understands SOCKS connect requests and
for each request open a TCP/IP tunnel over SSH to the requested host
and port.

* Added support in SSHProcess for I/O redirection to file objects that
implement read(), write(), and close() functions as coroutines, such
as the "aiofiles" package. In such cases, AsyncSSH will automaically
detect that it needs to make async calls to these methods when it
performs I/O.

* Added support for using pathlib objects in SSHProcess I/O redirection.

* Added multiple improvements to pattern matching support in the SFTPClient
glob(), mget(), mput(), and mcopy() methods. AsyncSSH now allows you
to use '**' in a pattern to do a recursive directory search, allows
character ranges in square brackets in a pattern, and allows a trailing
slash in a pattern to be specified to request that only directories
matching the pattern should be returned.

* Fixed an issue with calling readline() and readuntil() with a timeout,
where partial data received before the timeout was sometimes discarded.
Any partial data which was received when a timeout occurs will now be
left in the input buffer, so it is still available to future read()
calls.

* Fixed a race condition where trying to restart a read() after a timeout
could sometimes raise an exception about multiple simultaneous reads.

* Changed readuntil() in SSHReader to raise IncompleteReadError if the
receive window fills up before a delimiter match is found. This also
applies to readline(), which will return a partial line without a
newline at the end when this occurs. To support longer lines, a caller
can call readuntil() or readline() as many times as they'd like,
appending the data returned to the previous partial data until a
delimiter is found or some maximum size is exceeded. Since the default
window size is 2 MBytes, though, it's very unlikely this will be needed
in most applications.

* Reworked the crypto support in AsyncSSH to separate packet encryption
and decryption into its own module and simplified the directory
structure of the asyncssh.crypto package, eliminating a pyca subdirectory
that was created back when AsyncSSH used a mix of PyCA and PyCrypto.
