If I understood the Travis documentation correctly, all environment variables will affect the cache id (including $CONFIG, in the case below). This would mean the two entries would still use a different cache even if $CACHE_NAME is the same. See, for example: https://travis-ci.org/github/qemu/qemu/jobs/735738551#L965 https://travis-ci.org/github/qemu/qemu/jobs/735738553#L967 Both build tasks have the same value for $CACHE_NAME, but they are fetching two different cache URLs: master/cache--linux-focal-50ba7438064455bdb04bb41dcde2c91c34bb797265fe435b84cee4bae7d9b61d--compiler-gcc.tgz master/cache--linux-focal-8991cfc9b7f3f268e7e50aff4218daa4c206597ae796c60643a84ed58bba0cfb--compiler-gcc.tgz On Tue, Sep 03, 2019 at 03:26:47PM +0200, Philippe Mathieu-Daudé wrote: > These jobs build different components but use the same > host features.
