Framework dSYM #2

Open drewcrawford opened 9 years ago

drewcrawford commented 9 years ago

Hello,

I've got a crash inside a framework that symbolicator doesn't handle correctly. I was able to manually symbolicate it with atos.

If you're still maintaining this tool, I'd be happy to provide an affected crashlog and enough information to reproduce.

agentsim commented 9 years ago

Yes, if you could attach it to the bug report that would be great.

drewcrawford commented 9 years ago

I can't attach arbitrary files to github issues, but I sent via email.

Some notes about this setup:

This is a crash from inside a unit test of a Mac framework. The "executable" in this case is xctest, which loads the actual test target itself, in this case NitrogenBench.xctest. That (test target) is where the crash actually occurred.

I can symbolicate this file by hand by using

xcrun atos -o /path/to/NitrogenBench.xctest/Contents/MacOS/NitrogenBench -l 0x10cda6000 0x000000010cdab74f
@objc NitrogenBench.TCPBenches.testBenchmarkLatencyMS (NitrogenBench.TCPBenches)() -> () (in NitrogenBench) (TCPBenches.swift:26)

Which as you can see produces a reasonable source code listing for the top item in the stack trace.

Looks like the dwarf line number symbols are stored differently. Maybe because it is a Swift compilation. I'll have to dig a bit further to fix this one.

May also be tooling-related. This sample is from

Xcode Version 7.0 beta (7A120f) OSX 10.11 (15A178w)

Does having Beta version of Xcode 7 installed along side 6.4 affect using this tool? It seems like my files aren't symbolicating successfully in the last few weeks.

agentsim commented 8 years ago

It is quite possible. Now that the GM is released, I'll try updating the dwarf library and see if that helps with resolving the symbols.

Are you familiar with this? https://github.com/MaheshRS/symbolication-plugin

I found this will searching for ways to symbolicate. It worked pretty well but sort of makes me nervous adding a third party plugin to Xcode.

agentsim commented 8 years ago

Haven't heard of that, but if it works I wouldn't be too worried about it being a plugin. I use a few plug-ins everyday with Xcode (I'd be lost without XVim!)
