The way we usually skip tests automatically is with a test prerequisite. You might look at t/test-lib.sh for the test_set_prereq and test_lazy_prereq calls and synthesize one (maybe LONG_PATHS) that meets your needs. You can then annotate those tests with the appropriate prerequisite. I expect that for long paths, you will hit a lot of the same issues as occur on Windows, where PATH_MAX may be very small. It might be valuable to expose this information as a build option and then set an appropriate variable in t/test-lib.sh. -- brian m. carlson / brian with sandals: Houston, Texas, US https://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: https://keybase.io/bk2204
