Compile Time Code Weaving in Go, Large Systems Debugging/Profiling
summary
A practical compile-time weaver for Go that injects instrumentation by generating new Go source so the result compiles and runs like normal code. It implements before/after advice, channel and function-wrapping, timers and latency tracing, plus validation hooks and rollbacks for accidental changes. The tool merges multiple aspects into runnable files, records timing and trace maps for requests, and exposes where early deployments found integration bugs — useful on large unfamiliar codebases but requires careful testing and some manual fixes in complex package layouts.
