mix release generate 'nil' folder about exrm

[bitwalker]

That's odd, definitely sounds like some kind of bug, just not sure if it's exrm or dynamo. Was this project on GitHub? I thought it was, but I can't recall the url. If so, I'll clone it and try to reproduce.

If not, could you tell me what the contents (recursively) of _build/prod are when you run MIX_ENV=prod mix compile?

Here's the repo: https://github.com/stevedomin/simple_dynamo_deploy

And here's a gist of the contents of _build/prod: https://gist.github.com/stevedomin/0a5832835262b6618cec

Interesting, did a clone of your project, mix do deps.get, compile, release, and there is no nil folder under the entire rel tree. I think it might've just been a fluke. A couple of questions though:

• If you delete that folder, and do mix do clean --all, deps.get, compile, release, does it come back?
• Does that folder appear only after running your app?
• What version of Elixir are you on (I'm running 0.13.1)?

I should have mentioned, that folder is created at the root of my project (along with a binary named 'relx' that I just noticed, don't know if that one is meant to be there too).

• It does come back when I run mix do clean --all, deps.get, compile, release
• It appears when I run the mix release only
• I'm on 0.13.1 too

Here's the screenshot of the root of the project:

Woah, strange. I just reran those commands and now it shows up for me too. I'll follow up when I know more.

[stevedomin]

Interesting. Glad you find a way to reproduce it too.

Well that was a fun dive. Check this out:

• Delete the nil folder
• Run MIX_ENV=prod mix do clean, compile

The nil folder comes back. Best I can tell there is some difference in the way that dynamo is compiled for prod. The issue is probably somewhere in here. As far as I can tell, the .compile.dynamo file should be in the root of the compile path, but at some point it must be joining a path to an interpolated string with a nil value. I don't think it's an issue, and doesn't seem to affect anything, but probably worth reporting to the dynamo project.

Ping :)

Closing this since it was a third party issue. If you need any help sorting it out, come find me on #elixir-lang :)

[stevedomin]

Yeah sorry for not getting back to you earlier, crawling under work atm but I'm going to look into that hopefully soon. Will let you know how it goes.

[stevedomin]

And thanks again for taking time to look into it.

[bitwalker]

No problem!
