Would have removed .. in heroku deploy log

Question

a few days ago I started to see

 Would have removed best_in_place (2.0.2)
 Would have removed thor (0.16.0)

in my heroku deploy output.

It used to say that it removed the gem.

anyone know what's up with that?

update

heroku updated to latest ruby 1.9.3 and bundler cache cleaned fine.

Answer 1

That's a bug in Heroku deployment configuration. It writes a file .bundle/config which has a line:

BUNDLE_DRY_RUN: false

When bundler loads this global config file, it translates this to :dry_run => "false" When it checks for this setting, it's checking settings[:dry_run], which is a string, which evaluates to true.

You can remove this line by some shell commands (heroku run bash):

mv -f .bundle/config .bundle/config.orig
sed '/BUNDLE_DRY_RUN/d' < .bundle/config.orig > .bundle/config

And then run

bundle clean

Answer 2

This is a bug in the bundler gem – essentially extra debugging info is being dumped to the screen. It should be patched in the next release. The removal would be from a cache, most likely because a newer version is available (latest best_in_place is 2.0.3, Thor 0.17.0). These can be safely ignored.
