From 26a07309a6e195fc2d0adc89dcc06f3994ae7603 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Sat, 19 Oct 2013 23:06:07 +0200 Subject: [PATCH 1/2] Revert "test-lib: support running tests under valgrind in parallel" This reverts commit ad0e6233320b004f0d686f6887c803e508607bd2. --valgrind-parallel was broken from the start: during review I made the whole valgrind setup code conditional on not being a --valgrind-parallel worker child. But even the children crucially need $GIT_VALGRIND to be set; it should therefore have been set outside the conditional. The fix would be a two-liner, but since the introduction of the feature, almost four months have passed without anyone noticing that it is broken. So this feature is not worth the about hundred lines of test-lib.sh complexity. Revert it.
