Version History

1.1 - unreleased

  • Chopsticks now uses a binary serialisation protocol for call results. This broadens the range of of what can be transferred over tunnels to include most primitive Python types.
  • Several bugs are fixed

1.0 - 2017-07-06

API Changes

  • New Queue API for asynchronous operations and scheduling different tasks onto different hosts.
  • Chopsticks can be imported and used on remote hosts (see Recursively tunnelling).
  • Functions defined in __main__ modules or Jupyter notebooks can now be sent to remote hosts.
  • Tunnels and Groups now connect lazily.
  • Tunnels and Groups can be used as context managers to ensure they are closed.
  • Tunnels and Groups can be reconnected once closed.
  • Tunnels and Groups now support set operations (union, difference, etc). Tunnels behave as a group of one tunnel.
  • New Group.filter() method allows filtering hosts by executing a function on each host.
  • Added a Sudo tunnel, to run as a different user on the local machine.
  • Added a sudo parameter to SSHTunnel, to run as root on a remote host.
  • New GroupResult.raise_failures() allows converting ErrorResult to exceptions.

Internal Changes

  • Parameters are now sent over the tunnels using a custom binary protocol, rather than JSON. This is more efficient for byte strings, as used in the importer machinery.
  • Automatically configure the highest pickle version to use based on what is supported by the host.

0.5 - 2016-08-07

  • Group.put() and Group.fetch() methods allow sending and receiving files from Tunnels in parallel.
  • Raise exceptions when Tunnel methods fail.

0.4 - 2016-07-24

  • Prefix lines of stderr from tunnels with hostname.
  • New Docker tunnel, to open a tunnel into a new container.
  • Added Sphinx documentation, on

0.3 - 2016-07-15

  • Added support for Python 3.

0.2 - 2016-07-13

  • Add Group for running operations on multiple hosts in parallel.

0.1 - 2016-07-12

  • Initial public version
