test.bash failures during reverse test and on system without BTRFS

[sdns575]

Hi,
I'm building an RPM packages using gocryptfs-v2.5.4 vendored on AlmaLinux 10. It works but when I run test.bash it reports errors:

1. One is about BTRFS test. On AlmaLinux and EL distro btrfs is not supported. The function is in tests/root_test/root_test.go [func TestBtrfsQuirks(t *testing.T)]. To avoid this problem I simply removed the code in the function where it requires mkfs.btrfs. Note: I tried also on a Debian 12 host where btrfs is not installed: same problem. There is a way to skip btrfs tests for system that does not use it?
2. The other is in reverse test

--- FAIL: TestAccessVirtualDirIV (0.00s)
correctness_test.go:142: should NOT be executable

during reverse test. The interested file is "/var/tmp/gocryptfs-test-parent-0/1772555044/b/gocryptfs.diriv"

This is encountered on AlmaLinux 10 and Debian 12.

There is a bug in the test suite or this version is too new for EL10 or Debian12?

Thank you in advance

Best regards.

Hi, looks like this on Debian 12. I don't get a reverse failure. Can you post your output?

PS: This is a bug in the tests, ignore it

test.bash: This affects the whole process. Please use the syscallcompat wrappers instead.

The btrfs thing, yeah, I could skip the test if mkfs.btrfs is not installed.

Do you run the tests as root?

Does it also fail as a normal user?

[sdns575]

The previous test was from root user.

Running the test using normal user I get:

[rfjakob]

Ok. Now add user_allow_other to /etc/fuse.conf and the tests should pass.

[sdns575]

Hi,
adding user_allow_other to fuse.conf solves the issue for simple user, but what about root user?

[rfjakob]

The tests expect to be run as a normal user. For the tests that should run as root, please use

make root_test

This will run the tests that should be run as root as root.

[sdns575]

Hi and thank you for your answer.

At this point what type of test I should run when creating the RPM packages?

[rfjakob]

Hi, please use the gocryptfs v2.6.0 release which automatically skips btrfs, and fixes the errors about ./vendor/golang.org/x/sys/unix/syscall_linux.go .

As for the tests, please run

make test
make root_test

[sdns575]

Hi,
thank you for your work. I will use 2.6.0 as suggested.

Best regards
