PDE/API Tools/Migration IDE Integration

Support usage scanning tools in IDE

The 3.6 API tools have support for usage scanning - allowing adopters to provide scans back to you on what API and internal code they're using. The tooling is ant task based. What we want is integration into the IDE so a scan can be loaded and any breaking changes will be marked as problems in the editor.

Main Components

UI for managing scans

• Preference page

Backend for managing scans

• Store in metadata?
• Needs to be more efficient than separate xml files

Incremental Builder

• Add to the existing API Tooling incremental builder
• Compare current type against use scan and return breakage

Marker Management

• Create markers for usage breaking changes
• Clean stale markers when content or use scans change
• Needs new error level settings

Performance

• Must have no impact when off (check error level settings at start)
• Use LRU caches as scan cannot be loaded into memory
• Full builds must be possible

Tests

• Complete test suite for incremental builder
• Enhance the performance tests

Additional Enhancements

Annotate method/type usage in editors

• When editor is open, methods/types being used are annotated

Support multiple scans

• Compare against all of them

Use Scan Updating

• Support for recognizing when a newer use scan is available
