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

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.

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.

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