This is generally only required if the compiler cannot automatically release the compiler modules - this is the case if the module body contain anonymous functions (because we don’t know if they wen’t used for spawning processes or stored somewhere). I don’t think it’s required for fastglobal.

EDIT: I’ve just checked the fastglobal code and it compiles the data modules using Erlang compiler and not the elixir one, so it does not affect it in any way.

Folks, please let us know if you tried the release candidate and if everything is fine. Even if you found no regressions, say so in the comments, otherwise we can’t know if everyone is quiet because nobody tried it yet or if because nobody found bugs. Hoping for the latter.

Documentation metadata

This is awesome idea! When I firstly saw related github issue I was so surprised, because I did not expect such useful change. I believe that it will simplify lots of things.

compile_time_purge_matching

I really love this. I will use it definitely in already maintained projects!

–failed flag

It will definitely help. Fortunately my tests are really fast.

[Code] Add Code.purge_compiler_modules/0 that purges any compiler module left behind. This is useful for live systems dynamically compiling code

Added on personal TODO list for rewrite plan of ex_api library!

[IO.ANSI] Add cursor movement to IO.ANSI

Awesome! It will definitely help creating console scripts.

I will try to find a time to test those changes in this weekend. Good work!

The Meeseeks tests run fine using the RC and OTP21.

Edit: And a larger Phoenix 1.2 project with a bunch of deps also runs its tests fine (RC and OTP21), though it did complain that I shouldn’t use length(res) > 0 in my tests.

Seems to work with Caravan and a Phoenix 1.3 app that we have. My Phoenix project using Abinsthe won’t compile for what l assume are the reasons that Ben mentioned.
