Refactor generate() method for improved maintainability

[JacobPEvans]

Problem

The generate() method in bin/goatsearch.py spans approximately 200 lines (232-430) and handles multiple responsibilities:

• Dataset listing (lines 240-265)
• Job status polling (lines 280-338)
• Result collection with pagination (lines 345-419)
• Event transformation (lines 399-414)
• Search metadata updates (lines 421-425)

While PEP 8 does not specify a maximum function length, the Clean Code in Python guide (TestDriven.io) recommends that functions should:

• Be comprehensible in 5-10 minutes of review
• Follow the Single Responsibility Principle
• Be easily testable

The current structure makes it difficult to:

• Test individual behaviors in isolation
• Understand the flow at a glance
• Modify one aspect without risking others

Proposed Refactoring

Extract logical sections into focused methods:

New Method	Lines	Responsibility
_list_datasets()	240-265	Handle no-query case, return datasets
_poll_job_status()	280-338	Poll until running/complete, yield status events
_collect_results()	345-419	Paginate and yield result events
_transform_event()	399-414	Convert API response to Splunk event format

After refactoring, generate() becomes orchestration:

def generate(self):
    if not self.can_run:
        return

    if not self.query and not self.sid:
        yield from self._list_datasets()
        return

    self._prepare_event_search()

    if not self.job_id:
        yield from self.event_log
        return

    yield from self._poll_and_collect_results()

Acceptance Criteria

• generate() reduced to orchestration logic (~30 lines)
• Extracted methods are single-responsibility
• No behavioral changes (refactor only)
• All existing functionality preserved
• Tests pass (if Add end-to-end test infrastructure for CriblSearch #26 is complete)
