From a513aced1dca420f47104c15102f1f7f068e5586 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Mon, 7 Apr 2025 22:42:22 -0700 Subject: [PATCH] tests: hash-collision-perf: avoid test hang on GNU/Hurd This test would hang on GNU/Hurd because the perl code we use to measure subsecond duration isn't ported, and that loop would never terminate. * tests/hash-collision-perf: Detect the always-0 small_ms, and skip the test.
