# Some overall notes on how this works
#
# * We smoke using the system provided latest, and custom built "oddball perls"
# The reason for not having a blanket matrix is to conserve travis resources
# as a full DBIC depchain isn't cheap
#
# * Minimum perl officially supported by DBIC is 5.8.3. This *includes* the
# basic depchain. On failure either attempt to fix it or bring it to the
# attention of ribasushi. *DO NOT* disable 5.8 testing - it is here for a
# reason
#
# * The matrix is built from two main modes - CLEANTEST = [true|false]. In
# the first case we test with minimal deps available, and skip everything
# listed in DBIC::OptDesps. Without CLEANTEST we bring the armada of RDBMS
# and install the maximum possible set of deps and configs
#
# * All builds/tests run under NUMTHREADS number of threads.
#
# * The way .travis.yml is fed to the command controller is idiotic - it
# makes using multiline `bash -c` statements impossible. Therefore to
# aid readability (our travis logic is rather complex), the bulk of
# functionality is moved to a script. More about the problem (and the
# WONTFIX "explanation") here: https://github.com/travis-ci/travis-ci/issues/497
#

# Smoke only specific branches to a) not overload the queue and b) not
# overspam the notification channels
# Furthermore if the branch is ^topic/ - the custom compiled smokes will
# not run at all, again in order to conserve queue resources
