v3.0.1 - Performance and Code Quality Improvements

Performance Improvements

CorrelationEngine (correlation.py)

• O(1) event removal: Changed from list to dict-based indexing for event storage
• Events now tracked by internal ID for constant-time removal from indexes
• Extracted common _sort_by_timestamp() helper method

Player.seek() (recording.py)

• Binary search: Uses bisect.bisect_left for O(log n) timestamp seeking (was O(n) linear search)
• Pre-builds timestamp index during file load

EventBuffer.get_events() (dashboard.py)

• Uses itertools.islice to avoid full list conversion for efficient event retrieval
• Optimized EventSerializer with attribute mapping dictionary

EtwStreamer (streamer.py)

• Cached event loop: Added _get_loop() helper to reduce asyncio.get_event_loop() overhead

Error Handling Improvements

OtlpFileExporter (exporters/otlp.py)

• Atomic file writes: Uses temp file + rename pattern for crash safety
• Added proper exception handling with logging for OSError, TypeError, ValueError

Player (recording.py)

• Added specific exception handling for JSONDecodeError, KeyError, OSError
• Uses logging for error diagnostics instead of silent failures

Code Quality

• Added logging throughout for better diagnostics
• Consistent use of type hints
• Improved code organization with helper methods
