# The test build matrix (stage: test) is constructed to test a wide range of
# configurations, rather than a single pass/fail. This helps to catch build
# failures and logic errors that present on platforms other than the ones the
# author has tested.
#
# Some builders use the dependency-generator in `./depends`, rather than using
# apt-get to install build dependencies. This guarantees that the tester is
# using the same versions as Gitian, so the build results are nearly identical
# to what would be found in a final release.
#
# In order to avoid rebuilding all dependencies for each build, the binaries
# are cached and re-used when possible. Changes in the dependency-generator
# will trigger cache-invalidation and rebuilds as necessary.
#
# These caches can be manually removed if necessary. This is one of the very
# few manual operations that is possible with Travis, and it can be done by a
# Bitcoin Core GitHub member via the Travis web interface [0].
#
# Travis CI uploads the cache after the script phase of the build [1].
# However, the build is terminated without saving the cache if it takes over
# 50 minutes [2]. Thus, if we spent too much time in early build stages, fail
# with an error and save the cache.
