recent issues with vendor/bundle gems

[mrbrdo]

Hi,

Great work on the repo. I am using a slightly modified version where I use puma instead of unicorn, but I believe the issue I am going to describe is somehow related to bundler (I'm not sure though). I wasn't sure where to get help so I'll start here, perhaps some of you had a similar problem or can provide insight.

Recently, I set up a new server with my Chef script, the same as I've been using for the previous servers. For some reason 2 things stopped working:

• ruby cronjobs
• puma script which uses prune_bundler (reloads Gemfile in master process on hot restart, I only have problems when this is turned on, but it worked fine on old server)

It seems rbenv/bundler is not loading my gems anymore from vendor/bundle.
For now to fix it, I had to do the following:

• to make cronjobs work, I had to create a file ~/.bundle/config and put this in it:

---
BUNDLE_PATH: vendor/bundle

It seems for some reason before adding this, it was ignoring the app/current/.bundle/config file. My cronjobs look like this:

0 * * * * /bin/bash -l -c 'source /etc/profile.d/rbenv.sh; cd /u/apps/myapp/current && RAILS_ENV=production bundle exec rake something'

• to make puma work, I had to add export GEM_HOME="$app/vendor/bundle/ruby/2.1.0" to my script

Note I don't have any of this on my old server and it works just fine.

Any idea what happened? I can see that rbenv version was updated from 0.4.0-143-g4d72eef to 0.4.0-146-g7ad01b2 on the new server, but I looked at the rbenv commits and it doesn't seem like anything was changed that could cause this. Bundler version changed from 1.7.9 to 1.9.1.
It seems like the problem could be due to bundler. With the above changes I can at least run things for now, but I want to understand what happened and especially get rid of the GEM_HOME hack.
Last time I merged your latest changes into my repo was on December 23 (ad74120).
Any help is appreciated!
