I’ve tried to decompile beam files in my release built by distillery in prod environment, and succeeded.
Following this document(compile — OTP 29.0.2 (compiler 10.0.1)), if beam is compiled with debug_info, it can be decompiled.
I want to prevent decompiling, but I can’t find any information about debug_info option in distilliery.
Do you have any idea about this issue?

Oh, sorry. I did
beam_disasm:file("./Elixir.MyApp.beam")and it’s not related todebug_info.It always possible to disassemble beam file.
Can’t I block it?

Disassembling is always possible.
Remember, disassembling is just reading the raw bytes of the files and giving them human readable representations. Not more, not less.
If you really wan’t to avoid disassembling by a third party, you are not allowed to give away the files away.
