# Coverity Scan can be configured through Travis addons, but this allows for
# more control over the build instructions and does not require the addition
# of a coverity_scan branch in the repository. travisci_build_coverity_scan.sh
# does more checks before it decides to download Coverity (around 500M), but
# these instructions assume Coverity Scan is not installed if the directory
# does not exist and expects the download to fail if the token is incorrect.
# Coverity Scan quota are not checked as the Coverity enabled build must only
# run from cron.

  # Conan will automatically determine the best compiler for a given platform
  # based on educated guesses. The first check is based on the CC and CXX
  # environment variables, the second (on Windows) is to check if Microsoft
  # Visual Studio is installed. On Travis CC and CXX are set to gcc on
  # Microsoft Windows targets as well, this has the undesired effect that MSVC
  # is not detected, unsetting CC and CXX solves that problem.
  #
  #
  # !!! IMPORTANT !!!
  #
  # Microsoft Windows instances freeze at "install:" if secure environment
  # variables are used. There is no option to export secrets only for
  # specified platforms. The "filter_secrets: false" option is used to disable
  # the filter for Microsoft Windows instances. This is not an issue if the
  # secret is removed from the environment at the earliest opportunity, before
  # risk of exposure, as secrets are always removed from the environment for
  # pull requests and are still filtered when exported to the environment. The
  # secret of course will not be available for Microsoft Windows builds, but
  # for Coverity Scan, that is fine.
