Backtracing Async functions (+Task return type) #535

Open HomerSimpson00007 opened 3 months ago

HomerSimpson00007 commented 3 months ago

Was using the Backtracer (Works very well!), But entountered a problem, when trying to trace an async function, the backtrace result is always the same, all functions originate from MoveNext function (Due to the Statemachine), example: 0x06301eb8+0x000 TBetterBinaryProtocol::WriteBinaryAsync 0x062ccf98+0x094 Thrift.Protocol.TProtocol.<WriteStringAsync>d__39::MoveNext

Any other idea to backtrace such functions?

it's good idea to share your code. I guess you need backtrace the WriteStringAsync function, or use tracer on target class(es)

No clue!
