From 44ab65763bbeb307a3431de284805325114a3d35 Mon Sep 17 00:00:00 2001 From: Lukas Larsson Date: Mon, 20 Feb 2017 10:31:42 +0100 Subject: kernel: Fail sticky_dir tc if module not sticky Running this test when for some reason stdlib has been unstickied could cause the emulator to die. So we check first to make sure that the expected files are sticky. --- lib/kernel/test/code_SUITE.erl | 36 ++++++++++++++++++++++-------------- 1 file changed, 22 insertions(+), 14 deletions(-) (limited to 'lib/kernel') diff --git a/lib/kernel/test/code_SUITE.erl b/lib/kernel/test/code_SUITE.erl index c5167efa56..5777b397b8 100644 --- a/lib/kernel/test/code_SUITE.erl +++ b/lib/kernel/test/code_SUITE.erl @@ -588,20 +588,28 @@ sticky_compiler(Files, PrivDir) -> [R || R <- Rets, R =/= ok]. do_sticky_compile(Mod, Dir) -> - %% Make sure that the module is loaded.
