From 127cff38809ea6c3a37ed3ce7f428cafdc38e2e1 Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Thu, 8 Jul 2021 04:30:00 -0500 Subject: Work around a posix violation in the croups filesystem that LTP requires. Posix says you removing a non-empty directory "shall fail" in both: https://pubs.opengroup.org/onlinepubs/9699919799.2018edition/functions/unlinkat.html https://pubs.opengroup.org/onlinepubs/9699919799.2018edition/functions/rmdir.html So toybox mv went ahead and unlinked the directory even if the contents hadn't all been deleted because posix guarantees it to be harmless. But cgroups (https://lwn.net/Articles/679786/) deletes the non-empty directory, thus the Linux Test Project's cgroups_fj_function test6 was failing with toybox mv because they depend on not triggering the posix violating behavior. Work around it by having mv DIRTREE_SAVE failing nodes and then check for a non-empty ->child in the COMEAGAIN as a signal not to unlink the dir. While I'm there do some code cleanup, add a cp -i test... --- tests/cp.test | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'tests/cp.test') diff --git a/tests/cp.test b/tests/cp.test index b0d5d3a4..3e25f6c6 100755 --- a/tests/cp.test +++ b/tests/cp.test @@ -140,6 +140,14 @@ testing '-u1' 'echo one>one; sleep .1; echo two>two; cp -u one two; cat two' \ 'two\n' '' '' testing '-u2' 'echo two>two; sleep .1; echo one>one; cp -u one two; cat two' \ 'one\n' '' '' +mkdir a b + +echo potato > a/one +echo potato > a/two +touch b/one b/two +testing '-i' 'cp -ri a/. b/. 2>/dev/null; cmp -s a/one b/one || cmp -s a/one b/two && echo yes' \ + 'yes\n' '' 'n\ny\n' +rm -rf one two a b # cp -r ../source destdir # cp -r one/two/three missing -- cgit v1.2.3
