Otherwise we fail like this on my Fedora 38 box:
=== RUN TestOverlay
DetectQuirks: tmpfs detected, no extended attributes except acls will work.
root_test.go:379: No user xattrs! overlay mount will likely fail.
15:15:57.957960 Unimplemented opcode OPCODE-51
root_test.go:398: mount: /tmp/gocryptfs-test-parent-0/3652394902/TestOverlay.2374697046.mnt/merged: wrong fs type, bad option, bad superblock on overlay, missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.
root_test.go:399: exit status 32
--- FAIL: TestOverlay (0.04s)
FAIL
Also fix the messed-up DetectQuirks bit test.
Our git version is v2+ for some time now, but go.mod
still declared v1. Hopefully making both match makes
https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work.
All the import paths have been fixed like this:
find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%
Issues were:
# github.com/rfjakob/gocryptfs/contrib/findholes/holes
contrib/findholes/holes/holes.go:136:2: unreachable code
# github.com/rfjakob/gocryptfs/tests/root_test_test
tests/root_test/root_test.go:139:2: unreachable code
Also make sure we actually run "go vet" against the whole
codebase.
Also fix incomplete uid restoration in TestSupplementaryGroups
and replace syscall.Setregid and friends with unix.Setregid and
friends.
This test is added to check if have problems handling a full disk.
The ticket https://github.com/rfjakob/gocryptfs/issues/550 states
that the full disk was not where the backing gocryptfs filesystem
was, but this has no effect on gocryptfs, so we test the harder
case.
