Split from #1229

This is a weird one.

Using the couchdbdev/ppc64le-debian-stretch-erlang-20.3.8.22-1 image, I tried different things and got errors from different packages that referenced this same 5.104235503814077e+38 value.

After more digging, I figure out that parseInt() and similar functions are returning this value when it should be returning NaN for non-integer inputs. Since NaN is a falsy in JS, you can imagine this can cause a ton of issues. Unfortunately I couldn't find out why this is happening nor any solutions. Maybe it's Docker related?

On couchdbdev/ppc64le-debian-stretch-erlang-20.3.8.22-1:

> root@b7f5e29e134c:/usr/src/couchdb-fauxton# node -v
v10.16.3
root@b7f5e29e134c:/usr/src/couchdb-fauxton# node
> parseInt('', 10)
5.104235503814077e+38
> parseFloat('')
5.104235503814077e+38
>

On my Mac:

➜  node -v
v10.16.3
➜  node
> parseInt('', 10)
NaN
> parseFloat('')
NaN
>

Were you running this on an Intel CPU or on a POWER platform?

My guess is it's a bug in qemu. I have on my plate to try a newer qemu (build from source) but I can't confirm.

It seems upgrading to node 12 is one workaround. I tested with the following Dockerfile:

FROM node:12-stretch-slim

RUN apt-get update && apt-get install -y git; \
    git clone https://github.com/apache/couchdb-fauxton.git; \
    cd couchdb-fauxton; \
    npm install --production && ./node_modules/grunt-cli/bin/grunt couchdb

Using base image node:10-stretch-slim results in the ERR_OUT_OF_RANGE error.

Also confirmed the workaround using our CI image created by NODEVERSION=12 ./build.sh platform debian-stretch and the following Dockerfile:

FROM couchdbdev/debian-stretch-erlang-20.3.8.22-1:latest

WORKDIR /usr/src

USER root

RUN apt-get update && apt-get install -y git; \
    git clone https://github.com/apache/couchdb-fauxton.git; \
    cd couchdb-fauxton; \
    npm install --production && ./node_modules/grunt-cli/bin/grunt couchdb
