Pull request overview

This pull request enables mypy's check_untyped_defs configuration to improve type safety across the codebase. The changes focus on adding explicit type annotations, converting static methods to class methods, and improving None-safety checks to satisfy mypy's stricter type checking requirements.

Changes:

Added explicit type annotations throughout the codebase (Optional types, union types, return types)
Converted @staticmethod decorators to @classmethod in command classes, changing logger initialization from __class__.__name__ to cls.__name__
Introduced ParserTest base class for parser tests to provide consistent test infrastructure
Updated Errors.exit_with_error calls to use named exception parameter consistently
Added defensive None checks and assertions to prevent AttributeError in code paths where Optional types are used

Reviewed changes

Copilot reviewed 72 out of 72 changed files in this pull request and generated 15 comments.

tabcmd/commands/datasources_and_workbooks/datasources_and_workbooks_command.py

    def __init__(self, args):
-        super().__init__(args)
+        pass


The init method now only contains 'pass' and ignores the 'args' parameter. This breaks the parent class contract if Server.init expects these arguments. Since this class inherits from Server and Server doesn't have an init, this change makes the init unnecessary. Consider removing the init method entirely rather than having an empty implementation that accepts but ignores parameters.

tests/commands/test_geturl_utils.py


    def test_parse_get_url_to_view_parts_without_slashes(self):
-        url = "views\wb name\\view-name"
+        url = "views\\wb name\\view-name"


The string has an incorrect escape sequence. It should be "views\\wb name\\view-name" (with double backslashes for proper escaping) or a raw string r"views\wb name\view-name". The current form "views\wb name\view-name" will be interpreted with a single backslash which is the intended behavior, but it's inconsistent with typical Python string escaping conventions for test data.

tabcmd/commands/user/create_site_users.py

                    number_of_errors += 1
                    logger.debug(number_of_errors)
-                    error_list.append(e.summary + ": " + e.detail)
+                    error_list.append(e.__class__.__name__) # + ": " + e.__cause__ or "Unknown")


This line appears to be incomplete and contains commented-out code. The comment suggests building an error message with "e.cause" but this is left incomplete with "+ ": " + e.cause or "Unknown")". Either complete the error message construction or remove the comment entirely. Additionally, just appending the class name without any additional context may not provide enough information for debugging.
