Release Compatibility Check

Verify compatibility between Dynamo and SGLang versions before a release. This catches breaking changes at the integration boundary.

Step 1: Gather Version Information

Check current versions and recent changes:

!cd /home/ubuntu/dynamo && git log --oneline -10

!cd /home/ubuntu/sglang && git log --oneline -10

!cd /home/ubuntu/dynamo && git describe --tags --always 2>/dev/null || echo "no tags"

!cd /home/ubuntu/sglang && git describe --tags --always 2>/dev/null || echo "no tags"

Step 2: Check API Compatibility

ConfigArgumentMerger

The ConfigArgumentMerger is a key integration point where Dynamo merges its configuration with SGLang's argument parser. Check for breaking changes:

1. Dynamo side: Look at how Dynamo creates and passes configuration:

   • components/src/dynamo/sglang/ - SGLang wrapper configuration
   • Check for changes to config structs or argument passing

2. SGLang side: Look at SGLang's argument parser:

   • python/sglang/srt/server_args.py - Server arguments
   • python/sglang/srt/configs/ - Configuration files
   • Check for added/removed/renamed arguments

3. Verify no mismatches: Ensure every argument Dynamo passes is still accepted by SGLang.

Argument Parsing

Check for changes in how arguments flow through the system:

1. Look at Dynamo's launch scripts: examples/backends/sglang/launch/
2. Compare with SGLang's expected arguments
3. Check for deprecated or renamed flags

Step 3: Check Python Binding Compatibility

The Rust-Python boundary is a common source of breakage:

1. Check PyO3 bindings: lib/bindings/python/src/
2. Check Python imports: Ensure all SGLang modules that Dynamo imports still exist
3. Check function signatures: Ensure functions Dynamo calls have not changed their signatures

cd /home/ubuntu/dynamo && grep -r "from sglang" components/ lib/ --include="*.py" | head -20
cd /home/ubuntu/dynamo && grep -r "import sglang" components/ lib/ --include="*.py" | head -20

Step 4: Run Integration Smoke Test

Build and run a minimal test to verify the integration works:

1. Build Dynamo:

   cd /home/ubuntu/dynamo/lib/bindings/python && maturin develop --uv && cd /home/ubuntu/dynamo && uv pip install -e .
   

2. Run aggregated SGLang example (simplest integration test):

   bash /home/ubuntu/dynamo/examples/backends/sglang/launch/agg.sh
   

3. Send test request and verify response

Step 5: Report

Summarize findings:

• Dynamo version: [version/commit]
• SGLang version: [version/commit]
• API compatibility: [pass/fail with details]
• Python binding compatibility: [pass/fail with details]
• Integration test: [pass/fail with details]
• Breaking changes found: [list any issues]
• Recommendation: [safe to release / needs fixes]
