I know this thread is two months old, but it is the only reference in
the official Heroku channels I have found referring to the dsl
conflict with the 1.9.2 stack and rake 0.9.x (I resorted to SO to find
a few more thorough explanations and possible solutions). If
documentation exists it would be great to know where for reference.
The conflict came about while fixing an issue with a crashed email
notification job. Turns out moving my stack from bamboo-ree(1.8.7) to
bamboo-mri(1.9.2) caused cron to throw 'uninitialized constant
Rake::DSL'.
Unfortunately this wasn't caught until we noticed nightly jobs had
stopped running.
Unfortunate as one of the jobs is a forum notification mass-mailer
that had a queue backed up for several days. ~2850 errant emails after
fixing the rake issue (5 minutes), our solution was to alter our Rake
file in the exact order below, adding "require 'rake/dsl_definition'"
_before_ "require 'rake'":
require File.expand_path('../config/application', __FILE__)
require 'rake/dsl_definition'
require 'rake'
Beyond changes to the stack, I'd second updating documentation for
cron, dj, workers, and proc/rake to include this potential conflict,
and methods to prevent the issue.
