Alex Crichton (Mar 26 2020 at 22:45): Alex Crichton (Mar 26 2020 at 22:45):ok so I know I've asked this before, but @Peter Huene can you remind me how to debug the .NET extension?
Alex Crichton (Mar 26 2020 at 22:45):https://github.com/bytecodealliance/wasmtime/pull/1415 is hitting a ton of concurrent panics and then a segfault in dotnet test on Linux for me
Alex Crichton (Mar 26 2020 at 22:46):so I'm basically trying to get things serialized so there's no concurrency, and then get a backtrace of where the panic happens
Alex Crichton (Mar 26 2020 at 22:46):I forget where to start though in terms of debugging :(
Alex Crichton (Mar 26 2020 at 23:05):Ok I figured out the source of the error (rebase conflict meant header differed from Rust implementation
Alex Crichton (Mar 26 2020 at 23:06):although knowing how to debug would probably still be good :D
Peter Huene (Mar 26 2020 at 23:09):I use the SOS extension on macOS and Linux: https://github.com/dotnet/diagnostics/blob/master/documentation/sos.md
Peter Huene (Mar 26 2020 at 23:10):specifically these instructions: https://github.com/dotnet/diagnostics/blob/master/documentation/installing-sos-instructions.md
Peter Huene (Mar 26 2020 at 23:11):the clrstack command will display a "mixed mode" stack to resolve the .NET JIT frames to their symbolic names
Peter Huene (Mar 26 2020 at 23:26):I'm reviewing the C API refactoring changes now.
Alex Crichton (Mar 26 2020 at 23:37):ok cool thanks! I'll hopefully remember this for next time
