Backlog is not initialized

[gootik]

I can't figure out why this is happening, but there are no crash logs or any errors. This works locally but not on a production machine. Here is a log of what I run:

(bidbox@127.0.0.1)4> Url2 = buoy_utils:parse_url(<<"http://localhost:7949/recommend">>).
{buoy_url,<<"localhost:7949">>,<<"localhost">>,
          <<"/recommend">>,7949,http}
(bidbox@127.0.0.1)5> buoy_pool:start(Url2, [{pool_size, 16}]).
ok
(bidbox@127.0.0.1)6> buoy:post(Url2, [{<<"content-type">>, <<"application/json">>}], <<"{}">>).

Some more info:

and some system info:

I think i have figured out the issue. relx is not including metal because of an issue in the .app.src file. I will verify and open PR in there.

Ah, good catch. I'll push a fix shortly.

[lpgauth]

Fixed in https://github.com/lpgauth/buoy/releases/tag/0.1.2

[gootik]

Awesome, thanks. But I think there is one more thing to be fixed now that metal is being included.

===> Errors generating release
          metal: Missing parameter in .app file: mod

I think the mod field is expected to be a tuple not a list in https://github.com/lpgauth/metal/blob/master/src/metal.app.src#L8.
