Changelog

1.5.0

New

• New topology.platforms.shell.PExpectBashShell class that allows to easily setup shells that uses bash.

Fixes

• Fixed small identation bug that caused the function get_shell() in the node API to return always None.

1.4.0

Changes

• The shell used to execute a command will now be logged.

New

• New low level shell API that allows to define a common behavior for all low level shell manipulation. This API is implemented by the topology.platforms.shell module.

• Two new high level API methods for accesing the low level shell API:

  myshell = mynode.get_shell('python')
  response = myshel.execute('1 + 1')

  Or using a context manager:

  with mynode.use_shell('python') as python:
      # This context manager sets the default shell to 'python'
      mynode('from os import getcwd')
      cwd = mynode('print(getcwd())')
  
      # Access to the low-level shell API
      python.send_command('foo = (', matches=['... '])

1.3.0

Changes

• Attribute injection will now try to match files on any subfolder of the search paths and not only on the search paths themselves.

Fixes

• Fixed critical bug in injection attribute not considering matches in some cases.

1.2.0

New

• Added new API for the topology nodes that allow to set the default shell. For example, you may now use mynode.default_shell = 'bash'.

• Documentation for the Attribute Injection feature was added.

• Improvements for file matching in attribute injection files. Now, if using pytest, all test folders passed as arguments will be used as search paths for relative files specified in the attribute injection file. With this, it is no longer required to use an absolute path, and this practice becomes deprecated.

Fixes

• Fixed a bug in attribute injection when using attribute=value as node identifier that caused all nodes with the attribute to use that value.

1.1.0

New

• Added a common stateprovider decorator to topology.libraries.utils that allows to easily inject state to an enode in a Communication library.

• Added a common NodeLoader class to topology.platforms.utils that allows a Platform Engine to find a load nodes for it’s platform.

1.0.1

Fixes

• Fixed fatal bug when running a single node topology without ports.

• Fixed new PEP8 checks on the codebase.

1.0.0

• Initial public release.
