[erlang-bugs] [erlang-patches] Properly handle export_all when looking for undefined callbacks

[Anthony Ramine]

export_all means that everything is exported, so seeing a warning about an undefined behaviour callback is quite weird and surprising and confusing.

At the very least, the message should be changed when export_all is used, maybe something like "warning: callback is not explicitly exported".

I still think this is a bug, you use export_all during development to avoid exporting warnings and/or errors.

If it is the latter case then I wouldn't consider this an error. Functions which are meant to be seen on the outside of a module should be explicitly exported, export_all is more a development/debugging hack. IMAO anyway. If it the first case where having an export_all means that no callback is seen then it is a bug.
