Changes
- Added
pssh.config.HostConfigfor providing per-host configuration. Replaces dictionaryhost_configwhich is now deprecated. See per-host configuration - https://parallel-ssh.readthedocs.io/en/latest/advanced.html#per-host-configuration - documentation. ParallelSSHClient.scp_sendandscp_recvwith directory target path will now copy source file to directory keeping existing name instead of failing when recurse is off - #183.pssh.clients.ssh.SSHClientwait_finishedtimeout is now separate fromSSHClient(timeout=<timeout>)session timeout.ParallelSSHClient.joinwith timeout now has finished and unfinished commands asTimeoutexception arguments for use by client code.
Fixes
ParallelSSHClient.copy_filewith recurse enabled and absolute destination path would create empty directory in home directory of user - #197.ParallelSSHClient.copy_fileandscp_recvwith recurse enabled would not create remote directories when copying empty local directories.ParallelSSHClient.scp_sendwould require SFTP when recurse is off and remote destination path contains directory - #157.ParallelSSHClient.scp_recvcould block infinitely on large - 200-300MB or more - files.SSHClient.wait_finishedwould not apply timeout value given.

Changes
- Added
ssh-pythonbased native client withrun_commandimplementation. ParallelSSHClient.joinwith timeout no longer consumes output by default to allow reading of output after timeout.
Fixes
ParallelSSHClient.joinwith timeout would raiseTimeoutbefore value given when client was busy with other commands - #207
ssh-python client at pssh.clients.ssh.ParallelSSHClient is available for testing. Please report any issues.
To use:
from pssh.clients.ssh import ParallelSSHClient
This release adds (yet another) client, this one based on ssh-python (libssh). Key features of this client are more supported authentication methods compared to ssh2-python.
Future releases will also enable certificate authentication for the ssh-python client.
Please migrate to one of the two native clients if have not already as paramiko is very quickly accumulating yet more bugs and the 2.0.0 release which removes it is imminent.
Users that require paramiko for any reason can pin their parallel-ssh versions to parallel-ssh<2.0.0.

Changes
- Moved socket polling to
gevent.select.pollto increase performance and better handle high number of sockets - #189 HostOutput.exit_codeis now a dynamic property returning eitherNonewhen exit code not ready or the exit code as reported by channel - #191ParallelSSHClient.get_exit_codesis now a no-op and scheduled to be removed in2.0.0.
Packaging
- Removed OSX Python 3.6 and 3.7 wheels. OSX wheels for brew python, currently 3.8, on OSX 10.14 and 10.15 are provided.
Fixes
- Native client would fail on using sockets with large file descriptor values - #189

Changes
- Removed libssh2 native library dependency in favour of bundled
ssh2-pythonlibssh2 library. - Changed native client forward agent default behaviour to off due to incompatibility with certain SSH server implementations.
- Added keep-alive functionality to native client - defaults to
60seconds.ParallelSSHClient(<..>, keepalive_seconds=<interval>)to configure interval, Set to0to disable. - Added
~/.ssh/id_ecdsadefault identity location to native client.
