This option was added by Rails 4 new application generator. However, the
`assets.digest` option is set to true by default, and recent Rails
versions don't even add this option to the environment files.
In commit 574133a5 we configured the development to use Dalli to cache
pages. However, cache is usually disabled in the development
environment.
When we upgraded to Rails 5 in commit eb36b7e2, we configured the
development environment to enable caching (using a memory store) when a
certain file is present, and to disable it when it's not. This
configuration makes more sense IMHO, and it was being overwritten by the
one previously mentioned.
After this change, using memcached is no longer required in the
development environment and the `DalliError: No server available` error
message is gone.
Metrics/LineLength: Line is too long.
RSpec/InstanceVariable: Use let instead of an instance variable.
Layout/TrailingBlankLines: Final newline missing.
Style/StringLiterals: Prefer double-quoted strings.
The logs are always stored in log/bullet.log
If you run the specs with `BULLET=true bin/rspec`:
* Any feature test which makes bullet angry will fail
If you run rails with `BULLET=true bin/rails s`:
* It will print the bullet logs in both the rails log and the bullet log
* It will show a footer on each page with the N+1 queries etc.
This commit allows us to use caching and Rails.cache.
Temporarily we configure the null store in all environments,
but those will probably be memcached in the future.
