[OTP-21] Deprecation of erlang:get_stacktrace() call

[Maxim Velesyuk]

Hi, the new Erlang 21 is deprecating erlang:get_stacktrace() in order to replace with a new feature to retrieve the stacktrace only in the catch clause. Currently I can see this call being used in xdb_lib.erl.

For now it is possible to silence the warning and make the project compilable. Another option would be to pass exception across all the calls between a catch and xdb_lib:raise, or overall exception strategy should be changed.

What do you think should be the best way to go about it?

I talked to @cabol , we agreed on replacing the erlang:raise/3 calls to error/1
