🐛 do not cancel context when rule parsing fails

[pranavgaikwad]

Summary by CodeRabbit

• Refactor
  • Simplified rule parsing initialization by removing mid-flight cancellation handling and consolidating error reporting. Parsing errors are still detected and surfaced with clearer context, streamlining startup while preserving reliability and observability.

Walkthrough

Removed the cancelFunc parameter from the internal parseRules function and its invocation in NewPipeAnalyzer. NewPipeAnalyzer now wraps parse errors with "unable to parse rules: %w". On parser.LoadRules error, parseRules returns the error directly and no longer attempts cancellation.

Changes

Cohort / File(s)	Summary
Rule parsing simplification kai_analyzer_rpc/pkg/service/pipe_analyzer.go	Removed cancelFunc parameter from parseRules signature; updated NewPipeAnalyzer to call parseRules(parser, rules, l) and wrap returned error with unable to parse rules: %w. parseRules now returns parser.LoadRules error directly without invoking cancellation.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Single-file change with a straightforward parameter removal and an adjusted error wrap.
• Areas to inspect:
  • NewPipeAnalyzer call site and error-wrapping semantics.
  • parseRules behavior on parser.LoadRules error to ensure no hidden cancellation dependency remains.

Poem

🐇 I hopped along a tidy trail,
One less string tugged from tail to tail,
Rules parsed neat, no sudden stop—
A lighter hop, a cleaner hop! ✨

Learning: In kai_analyzer_rpc/pkg/rpc/server.go, panic on analyzer service initialization failure is intentional to ensure the process ends when the core service cannot be created, following a fail-fast approach.

Timestamp: 2025-09-10T22:52:55.595Z
Learning: In kai_analyzer_rpc/pkg/service/analyzer.go, the analyzer only receives file paths from within the workspace, so path normalization before cache operations is not needed as paths are already consistently formatted.

96-99: LGTM! Correct fix for context cancellation behavior.

The removal of cancelFunc from parseRules is appropriate. The deferred cancelFunc() at line 48 already ensures proper context cleanup on function exit. The error wrapping with %w preserves the original error chain for better debugging.

---

197-207: LGTM! Clean separation of concerns.

Removing context cancellation responsibility from parseRules improves cohesion—the function now focuses solely on parsing. Context lifecycle management properly remains with the caller. The error is logged with sufficient detail (file path) before being returned.
