Revision b4a2fdc9bdc87fc8bd62e8bf7890482c590e558c authored by SZEDER Gábor on 31 December 2017, 10:12:04 UTC, committed by Junio C Hamano on 02 January 2018, 19:25:57 UTC
It seems that Travis CI creates the cache directory for us anyway, even when a previous cache doesn't exist for the current build job. Alas, this behavior is not explicitly documented, therefore we don't rely on it and create the cache directory ourselves in those build jobs that read/write cached data (currently only the prove state). In the following commit we'll start to cache additional data in every build job, and will access the cache much earlier in the build process. Therefore move creating the cache directory to 'ci/lib-travisci.sh' to make sure that it exists at the very beginning of every build job.
