Summary

  • Reduce default heap from 2GB to 1GB
  • Expand decompiled class LRU cache (5→50) to reduce repeated decompilation
  • Add in-memory cache layer to CachedClassPathResolver to avoid repeated DB transactions
  • Enable SQLite WAL mode and NORMAL synchronous for better I/O performance

Changes

File Change
server/build.gradle.kts Heap 2GB→1GB
ClassContentProvider.kt LRU cache 5→50
CachedClassPathResolver.kt In-memory cache layer
DatabaseService.kt SQLite WAL mode + NORMAL sync

Expected Impact

~30-45% memory reduction while maintaining LSP responsiveness.

fix: support go-to-definition for top-level val/var in generated code
33c7fd4 
- Add val/var to definitionPattern regex for definition lookup
- Allow build/generated-src directory by excluding specific build outputs
  instead of entire build directory

This fixes go-to-definition failing for generated code like jOOQ Tables.kt

perf: add JVM memory limits to prevent excessive memory usage
b314665 
- Set initial heap to 256MB, max heap to 2GB
- Use G1GC for better memory management
- Enable string deduplication to reduce memory footprint

This prevents the language server from consuming 3GB+ of memory
