* btrfs-progs: tests: Move fsck-tests/015 to fuzz testsQu Wenruo2017-03-08
| | | | | | | | | | | The test case fsck-tests/015-check-bad-memory-access can't be repair by btrfs check, and it's a fortunate bug makes original mode to forget the error code from extent tree, making original mode pass it. So fuzz-tests is more suitable for it. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: tests: 001-simple-unmounted: fix test failure due to bashismLuis Henriques2016-07-04
| | | | | | | | | | | | | | | | | | The usage of 'source' is a bashism, and '.' should be used instead. This is causing fuzz-tests/001-simple-unmounted to fail in systems where /bin/sh isn't bash: [TEST/fuzz] 001-simple-unmounted ./test.sh: 5: ./test.sh: source: not found ./test.sh: 7: ./test.sh: setup_root_helper: not found ./test.sh: 8: ./test.sh: check_prereq: not found ./test.sh: 18: ./test.sh: check_all_images: not found Since most (all?) tests actually use /bin/bash, change this test to use bash too.

A collection of several images that were produced in a non-standard way and cause various errors in check or image tools. They do not fit into the fsck tests as we're not able to repair any of them, but the tools should not crash or do out-of-bounds access. Signed-off-by: David Sterba <dsterba@suse.com>
