学习 CUE 内部工作原理的提示

最重要的部分是求值器，在

• internal/core/{eval,adt}

包括的事项：

• 顶级 struct
• 顶级 function
• 在求值过程中的数据结构
• 它们的关联

之前的步骤

(v0.3.0-alpha)

Was experiencing slowdowns in hof gen with the new evaluator

• add pprof with CUE_PPROF
• find go’s memory system is heavy
• filter for cue’s functions mainly involved
• find cycle around 5-6 functions in the evaluator system
• use delve to start following a simple eval, didn’t get very deep
• switch to printf to see high level flow
• start trying to find entry into evaluator, many new context (repeated prints)
• … where is the entry point to this one file’s evaluation?
• … Validate() from setting breakpoint in delve (for NEW CONTEXT) and checking backtrace
• … set breakpoint at cue.Value.Validate()
