- Install GraalVM CE 25.0.1 via SDKMAN setup script - Add GraalVM Polyglot and Python dependencies to build.sbt - Add PythonExample.scala to verify Python integration
- Implement simple Scala-Python binding using Val.Builtin - Verify dictionary argument passing and integer return value from Jsonnet
- Add PythonSupport.scala with PythonEvaluator and PythonMapper - Integrate GraalVM Polyglot for Python module loading and data conversion - Update PythonInteropTest to verify importpy and Python function calls from Jsonnet
…luation - Update PythonEngine to share a single Engine and cache Source objects - Refactor PythonContextManager to manage a single Context and module cache per evaluation - Integrated Python context management into SjsonnetMainBase using Platform hooks - Verified shared state across multiple importpy calls in a single evaluation
…ctural caching - Move code to sjsonnet.starlark package and directory - Rename all Python references to Starlark (importstarlark, StarlarkEngine, etc.) - Implement global structural caching of context-independent Val objects - Use ThreadLocal to link cached Val objects to the current evaluation context - Add comprehensive README explaining the architecture and performance optimizations - Update Platform hooks and main entry points to support the new Starlark integration
- Reimplement several stdlib-like functions in Python for comparison - Add StarlarkBenchmark with JMH integration - Update build.mill to include Starlark benchmark resources - Implement robust path resolution for benchmark data
- Restructure benchmark to reuse StarlarkContextManager across iterations - Focus on pow benchmark to minimize Polyglot boundary crossing - Update JMH settings to 20s warmup and 15s measurement - Results show Starlark (0.005 ms/op) is 5x faster than Jsonnet (0.025 ms/op) for contained logic
- Restore makeArray, floor, ceil, sqrt, filter, and map benchmarks - Update benchmarks.py with all necessary functions - Keep optimized JMH settings (20s warmup, 15s measurement) - Support selective execution via JMH regex (e.g. .pow)
- Finalize ProxyExecutable bridging in StarlarkSupport - Consolidate StarlarkBenchmark suite with optimized timing - Remove experimental host-bridging code
- Implement recursive freezing of user-defined globals post-module load - Optimize valToPy to pass raw Graal Values for Starlark-backed Jsonnet values - Add StarlarkSemanticsTest to verify local mutability vs global immutability - Update setup script to include Go and official Starlark interpreter for validation
- Add expensive.py with a 1M iteration loop to test re-execution cost - Add StarlarkPartialEvalBenchmark JMH test - Verified that JIT compilation is shared while execution remains per-context
…ffle support - Re-enable Starlark global freezing logic for hermeticity - Implement Java-centric iteration (forEach) for improved polyglot performance - Add Truffle API dependency and 'Tiny' language implementation for performance baselining - Add StarlarkAllocationBenchmark to compare immutable vs mutable update strategies - Update build.mill and build.sbt with new dependencies and resource paths
