Lexicon v3.14.0

Added

• New way to invoke Lexicon as a library: lexicon.client.Client becomes a context manager.
  When invoked with the with keyword, it will provide an operation object that embeds the
  target provider fully authenticated (authenticate method called on the Provider).
  This operation object gives access to four methods: create_record, update_record,
  delete_record and list_records. These methods can be invoked instead of the old
  execute method to execute a specific action on the DNS zone. In this case, type,
  name, content fields do not need to be set in the config anymore, since they are
  passed directly as arguments to the new methods. Upon context manager closing, the cleanup
  method defined in the Provider is ensured to be called. See the README file of the project
  for an example of how to use this new approach.
• Python warnings are emitted from the code to alert about the deprecations listed below.

Modified

• Former NAMESERVER_DOMAIN variable and provider_parser function that had to be defined
  in each provider module are respectively migrated to get_nameservers
  and configure_parser static methods in each Provider class. They are defined as abstract
  in the interface and must be implemented in the concrete classes.
• Former private methods _create_record, _modify_record, _delete_record
  and _list_records are migrated to their public counterpart create_record,
  modify_record, delete_record and list_records in each Provider class. These are
  the new abstract methods for each action that need to be implemented.
• Method lexicon.client.Client.execute is deprecated and will be removed in Lexicon 4.
• Package lexicon.providers, containing the actual provider implementations, is migrated to
  lexicon._private.providers. The provider implementations are not supposed to be used
  directly, please use lexicon.client.Client instead with the new methods described above.
  Package lexicon.providers stubs to lexicon._private.providers to ease the migration
  path, but it is deprecated and will be removed in Lexicon 4.
• Module lexicon.providers.base, that contains the Provider interface to implement, is
  migrated to module lexicon.interfaces. Module lexicon.providers.base stubs
  to lexicon.interfaces to ease the migration path, but it is deprecated and will be removed
  in Lexicon 4.
• Modules lexicon.cli, lexicon.parser and lexicon.discovery are migrated to the
  private package lexicon._private as they are not part of the public API. Old modules
  stubs to the new modules in the private package lexicon._private to ease the migration path,
  but it is deprecated and will be removed in Lexicon 4.
• Update documentation, in particular the developer guide, to take into account the new
  architecture of the code to implement a new Provider.
• Functional codebase in /lexicon folder is moved in /src/lexicon folder to comply with
  modern Python project layouts. Tests are migrated to /tests folder.

Removed

• Drop support for Python 3.7
