Network Topology Framework using NML, with support for pytest.
Advanced modular framework for building and testing network topologies and Software.
- Calling missing super.
- Fixing typo in README.
- Making StepLogger backwards compatible.
- Fixing broken step logger.
- Fixing the test_id marker to make it work with Pytest > 3.0.0.
- Removing fixed dependencies.
- Adding logging functionality.
- Fixing the shells connect process.
- Handling calls to decode safely.
- Removed internal imports of deprecated modules.
- A new ServicesAPI for the nodes is now available. This new API allows to register and later on fetch information about the services a node provides.
- Greatly improved documentation for the Shell Low Level API introduced in 1.4.0. Check “The low-level shell API” in User Guide.
- The Low Level Shell API will now be able to log user commands. This new feature is backward compatible.
Module topology.platforms.base is now deprecated. Please change your imports to:
topology.platforms.base.BasePlatform => topology.platforms.platform.BasePlatform topology.platforms.base.BaseNode => topology.platforms.node.BaseNode topology.platforms.base.CommonNode => topology.platforms.node.CommonNode
- Adding user as an option for PExpectShell to support shells that use this kind of authentication.
- Raising the proper exception when a shell connection fails for the user to handle it properly.
- Removing the version requirement of Pexpect since this may cause version collisions with other Python packages commonly used with the framework.
- The documentation for communication libraries has been improved a lot with specific examples for common use cases added.
- The pexpect spawn arguments are now reachable from the initialization of a shell object.
- The attribute injection feature is now capable of following symbolic links while walking through directory paths.
- The version of all dependencies has been fixed. This is to avoid unexpected code breaks when a bug is introduced in one of them.
- The reference documentation for the vtysh, ping and ip communication libraries has been added to the documentation.
- PExpect shells now support multiple connections. This means that the same shell object can now use several pexpect spawn objects.
- The base node class BaseNode now includes a ports attribute. This has been used by all platform engine nodes so far, but was missing in their base class.
- A missing history file does not raise an error whene executing topology, but is just logged as an error.
- A few CSS and other theme issues have been fixed.
- When expanding the search path for attribute injection all hidden folders (starting with ‘.’) will now be ignored.
- When processing files that matched the search path for attribute injection all files that have ill formed / unparseable SZN strings will be logged as error and skipped instead of raising an exception.
- When processing files that matched the search path for attribute injection all .py’s that doesn’t possess a TOPOLOGY variable will now be warned and skipped instead of raising an exception.
- Fixed attribute injection crashing when a SZN file is in the node expansion search path.
- Fixed rollback routine not being triggered when an non Exception subclass is raised.
- New topology.platforms.shell.PExpectBashShell class that allows to easily setup shells that uses bash.
- Fixed small identation bug that caused the function get_shell() in the node API to return always None.
- The shell used to execute a command will now be logged.
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 = myshell.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=['... '])
- Attribute injection will now try to match files on any subfolder of the search paths and not only on the search paths themselves.
- Fixed critical bug in injection attribute not considering matches in some cases.
- 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.
- Fixed a bug in attribute injection when using attribute=value as node identifier that caused all nodes with the attribute to use that value.
- 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.
- Fixed fatal bug when running a single node topology without ports.
- Fixed new PEP8 checks on the codebase.
- Initial public release.
