• v2.3.2 Changes

  December 09, 2020

  🛠 Fixes

  • 👍 Client output implementation Python 2 support.

• v2.3.1 Changes

  December 06, 2020

  🔄 Changes

  • SSHClient.read_output and read_stderr now take buffer to read from as argument instead of channel.
  • SSHClient.wait_finished now takes HostOutput argument instead of channel.

  🛠 Fixes

  • Output for multiple commands on one host run at the same time would be lost.

• v2.3.0 Changes

  December 04, 2020

  🔄 Changes

  • SSHClient now starts buffering output from remote host, both standard output and standard error, when a command is run.
  • SSHClient.read_output, SSHClient.read_stderr and iterating on stdout/stderr from HostOutput now read from the internal buffer rather than the SSH channel directly.
  • ParallelSSHClient.join no longer requires consume_output to be set in order to get exit codes without first reading output.
  • 0️⃣ ParallelSSHClient.join with timeout no longer consumes output by default. It is now possible to use join with a timeout and capture output after join completes.
  • ParallelSSHClient.reset_output_generators is now a no-op and no longer required to be called after timeouts.
  • HostOutput.stdout and stderr are now dynamic properties.
  • 👀 Added HostOutput.read_timeout attribute. Can be used to see what read timeout was when run_command was called and to change timeout when next reading from HostOutput.stdout and stderr.
  • ➕ Added HostOutput.encoding attribute for encoding used when run_command was called. Encoding can now be changed for when next reading output.
  • ⏱ ParallelSSHClient.join with timeout no longer affects stdout or stderr read timeout set when run_command was called.
  • LibSSH clients under pssh.clients.ssh now allow output to be read as it becomes available without waiting for remote command to finish first.
  • Reading from output behaviour is now consistent across all client types - parallel and single clients under both pssh.clients.native and pssh.clients.ssh.
  • 0️⃣ ParallelSSHClient.join can now be called without arguments and defaults to last ran commands.
  • 0️⃣ ParallelSSHClient.finished can now be called without arguments and defaults to last ran commands.

  This is now possible:

     output = client.run_command(<..>)
     client.join(output)
     assert output[0].exit_code is not None
  

  As is this:

     client.run_command(<..>, timeout=1)
     client.join(output, timeout=1)
     for line in output[0].stdout:
         print(line)
  

  ⏱ Output can be read after and has separate timeout from join.

  📚 See documentation for more examples on use of timeouts.

• v2.2.0 Changes

  December 01, 2020

  🔄 Changes

  • 🆕 New single host tunneling, SSH proxy, implementation for increased performance.
  • Native SSHClient now accepts proxy_host, proxy_port and associated parameters - see API documentation
  • 🔧 Proxy configuration can now be provided via HostConfig.
  • ➕ Added ParallelSSHClient.connect_auth function for connecting and authenticating to hosts in parallel.

• v2.1.0 Changes

  October 25, 2020

  🔄 Changes

  • ➕ Added certificate authentication support for the pssh.clients.ssh clients.

• v2.1.0.post1

  October 25, 2020

• v2.0.0 Changes

  October 06, 2020

  🔄 Changes

  ⬆️ See Upgrading to API 2.0 for examples of code that will need updating.

  • ✂ Removed paramiko clients and dependency.
  • ParallelSSHClient.run_command now always returns a list of HostOutput - return_list argument is a no-op and will be removed in future releases.
  • ParallelSSHClient.get_last_output now always returns a list of HostOutput.
  • SSHClient.run_command now returns HostOutput.
  • ✂ Removed deprecated since 1.0.0 HostOutput dictionary attributes.
  • ✂ Removed deprecated since 1.0.0 imports and modules.
  • Removed paramiko based load_private_key and read_openssh_config functions from pssh.utils.
  • ✂ Removed paramiko based pssh.tunnel.
  • ✂ Removed paramiko based pssh.agent.
  • ✂ Removed deprecated ParallelSSHClient.get_output function.
  • Removed deprecated ParallelSSHClient.get_exit_code and get_exit_codes functions.
  • ✂ Removed deprecated ParallelSSHClient host_config dictionary implementation - now list of HostConfig.
  • ✂ Removed HostOutput.cmd attribute.
  • ✂ Removed ParallelSSHClient.host_clients attribute.
  • ⏱ Made ParallelSSHClient(timeout=<seconds>) a global timeout setting for all operations.
  • Removed run_command(greenlet_timeout=<..>) argument - now uses global timeout setting.
  • ⏱ Renamed run_command timeout to read_timeout=<seconds>) for setting output read timeout individually - defaults to global timeout setting.
  • ✂ Removed pssh.native package and native code.
  • 👍 ParallelSSHClient.scp_send now supports copy_args keyword argument for providing per-host file name arguments like rest of scp_* and copy_* functionality.
  • 🔄 Changed exception names to end in Error from Exception - backwards compatible.
  • UnknownHostException, AuthenticationException, ConnectionErrorException, SSHException no longer available as imports from pssh - use from pssh.exceptions.

  🛠 Fixes

  • ✂ Removed now unnecessary locking around SSHClient initialisation so it can be parallelised - #219.
  • ParallelSSHClient.join with encoding would not pass on encoding when reading from output buffers - #214.
  • ⏱ Clients could raise Timeout early when timeout settings were used with many hosts.

  Packaging

  • 📦 Package architecture has changed to none-any.

• v2.0.0.rc1 Changes

  October 03, 2020
