Ability to load extensions in dotnet-dump analyze #1031

Open joseotavioq opened 4 years ago

joseotavioq commented 4 years ago

It would be amazing if we can load extensions in dotnet-dump analyze, like "mex", "sosex", "netext".

This is a great idea but actually implementing it has some problems. SOS had to be changed to be "hostable" under dotnet-dump. Some of the dbgeng APIs were hard or impossible to implement so changes were made on in the SOS native code (i.e. the cdecl variable-parameter Output* functions). And there are quite a few of the many dbgeng interfaces that are not implemented which we don't currently have the resources.

"mex" is mostly managed code and would need to change to hook into dotnet-dump and dotnet-dump needs more work to provide these hooks. It looks like it works for the desktop CLR and Windows only.

"sosex" is an external extension that also is desktop/Windows only and hasn't been updated since 2016.

"netex" works only on desktop/Windows and would need work to be hostable under dotnet-dump.
