Framework-Aware Debugging with Stack Tailoring
summary
Sarto is a library that instruments call stacks and exposes six concrete operations so frameworks can hide, inject, or join frames. It implements stack cutting to remove framework internals, crafting a stack frame to insert synthetic setup frames, concatenate call stacks to show promise creation plus resolution as one trace, and stack comparison/delta/application to relate parallel exceptions. Implementations cover an HTTP server, unit tests, promises and a parallel framework and benchmarks report no noticeable runtime overhead.
