# 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.

# Notes on test settings:
# - CYCLONEDDS_URI:
#   - EnableExpensiveChecks: for the few horrendously expensive (but pretty thorough)
#     integrity checks, in particular on the WHC and the RHC, but there may be more
#   - config to stderr: gives the configuration used when running the test in conjunction
#     with "--output-on-failure" (sadly that still doesn't output the failed
#     assertions ...)
# - -j 4: run 4 tests in parallel, this saves quite a bit of time because the VMs are
#   all dual-core
# - --output-on-failed: print whatever output the test generated when it failed, which
#   can obviously be quite helpful for debugging
# - -E ...: regex of tests to exclude:
#     CUnit_ddsrt_random_default_random: performs a Chi-square test on the output of
#     the random generator, but this does produce the odd failure (it should!).  The
#     code has been vetted, the test has been run a great many times (with the odd
#     failure), and so we now simply skip the test to avoid the spurious failures.
