Revision e91d1a21a6ad7dc4eb4ce46c5b3f6ad550357640 authored by Peter Dillinger on 27 March 2020, 02:34:06 UTC, committed by Facebook GitHub Bot on 27 March 2020, 02:36:32 UTC
Summary: This test was written like a stress test, using up to 3x26GB RSS memory during parallel 'make check'. Now, while this code is mostly dormant, I've made the "for Travis" versions of the expensive tests the canonical versions and disabled the expensive versions. This has the side benefit of removing some arbitrary conditional compilation. For unknown reason, the super expensive tests were gated on Snappy_Supported, which appears to be irrelevant, so I removed it. The tests can be fixed / improved / migrated to stress test if/when they are deemed important again.
