go-graphviz v0.2.10

[eguzki]

Summary

Updates github.com/goccy/go-graphviz from v0.2.9 to v0.2.10 to fix a segmentation fault in the topology command.

Problem

The kuadrantctl topology --svg command was experiencing a segmentation fault when attempting to render topology data that contained error messages (specifically when the topology exceeds the ConfigMap 1MB limit). The crash occurred in the runtime's garbage collector during the DOT graph parsing phase.

Error example:

SIGSEGV: segmentation violation
PC=0x46ff45 m=15 sigcode=1 addr=0x110

goroutine 0 gp=0xc0001d1180 m=15 mp=0xc00051f008 [idle]:
runtime.(*unwinder).next(0x7f9cea7fbaf8)
runtime.memmove()

Solution

Upgrading to go-graphviz v0.2.10 resolves the parsing issue. The library now correctly handles edge cases in DOT graph parsing that previously caused memory corruption and crashes.

Changes

• Updated github.com/goccy/go-graphviz from v0.2.9 to v0.2.10
• Updated transitive dependency github.com/tetratelabs/wazero from v1.8.1 to v1.10.1

Testing

Verified that bin/kuadrantctl topology --svg ~/tmp/topology.svg now:

• Completes successfully without segmentation fault
• Correctly generates SVG output displaying the error message when topology exceeds ConfigMap limits
• No longer crashes on edge case DOT graph inputs

Impact

• Fixes critical crash that prevented users from using the topology visualization feature
• No breaking changes or API modifications
• Backward compatible dependency update

Summary by CodeRabbit

• Chores
  • Updated underlying Graphviz and WebAssembly runtime components to newer versions.
  • No user-facing features or behaviour changes were introduced.
