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/%
Everything except the
if err2.Err == syscall.EOPNOTSUPP
case. Gets too confusing when collapsed into a single line.
Issues were:

gocryptfs 2.0 introduced the regression that the size
reported at symlink creation was the ciphertext size,
which is wrong.
Report the plaintext size.
Fixes https://github.com/rfjakob/gocryptfs/issues/574
As discovered by xfstests generic/401 [1], during the move to
the v2 api we seem to have lost the "." and ".." directory
entries.

Chasing a bug that seems to have nothing to do
with magic names, as it already triggers during
warmup:
--- FAIL: TestMagicNames (0.00s)
matrix_test.go:773: Testing n="warmup1"
matrix_test.go:773: Testing n="warmup2"
matrix_test.go:820: no such file or directory
When running
$ go test ./tests/matrix/
in isolation, it failed like this:
fd leak? before, after:
[0r=/dev/null 3w=/dev/null 5r=/proc/8078/fd (hidden:4)]
[0r=/dev/null 3w=/dev/null 5w=/tmp/go-build366655199/b001/testlog.txt 7r=/proc/8078/fd (hidden:4)]
Filter by prefix to get rid of this spurious test failure.
This should get rid of
Openat: O_NOFOLLOW missing: flags = 0x0
Fchmodat: adding missing AT_SYMLINK_NOFOLLOW flag
sys_common_test.go:203: chmod on symlink should have failed, but did not. New mode=0333
UnmountErr: "[...]/057376762.mnt" was not found in MountInfo, cannot check for FD leak
and add some context to
--- FAIL: TestUtimesNano (0.00s)
matrix_test.go:628: no such file or directory
See https://github.com/rfjakob/gocryptfs/pull/343#issuecomment-453888006
for full test output
Instead of reporting the consequence:
matrix_test.go:906: modeHave 0664 != modeWant 0777
Report it if chmod itself fails, and also report the old file mode:
matrix_test.go:901: chmod 000 -> 777 failed: bad file descriptor
And fix two in test_helpers.Mount().
Leftover fds can cause an unmount failure like this later:
fusermount: failed to unmount /tmp/gocryptfs-test-parent/873632270/default-plain: Device or resource busy
so try to catch them early.
macos does not have lazy unmount, so let's not use it
on linux either.
If the unmount fails, run "lsof" to find the open file.
Also fix the first bug we found this way.
We relied on the finalizer to close a few fds.
For some reason, this did not cause problems on Linux,
but on MacOS, it causes unmount failures:
umount(/private/tmp/gocryptfs-test-parent/194654785/default-plain): Resource busy -- try 'diskutil unmount'
