On Fedora, /tmp is tmpfs, which behaves differently than ext4
(inode numbers are never reused, for example).
Use /var/tmp, which is ext4 on Fedora, to get a more realistic
test environment.
This also allows us to drop the xattr workaround.
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.
When we run tests as root, they will leave root-owned files
in testParentDir, which causes trouble when we run tests as
a normal user later on. Split by UID.
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
Give the gocryptfs process one extra millisecond to close
files. Allows us to drop several other sleeps.
UnmountErr now really returns an error when it detects an fd leak
instead of just printing a message.
When mounted via /etc/fstab like this,
/a /b fuse.gocryptfs default 0 0
we always get extra options passed. As reported by @mahkoh
at https://github.com/rfjakob/gocryptfs/pull/233 :
mount passes `-o noexec` if `-o user` is set and `-o exec` is not set.
If both `-o user` and `-o exec` are set, it passes `-o exec`.
Make these options work, and in addtion, also make -suid and -rw
work the same way.

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.
Most corruption cases except xattr should be covered.
With test filesystem.
The output is still pretty ugly. xattr support will
be added in the next commits.
SwitchTestParentDir changes testParentDir. This is used when you want
to perform tests on a special filesystem. For example, the xattr tests
cannot run on tmpfs and use /var/tmp instead of /tmp.
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.
To Go test logic waits for stderr and stdout to close, so
when we share it with a subprocess, it will wait for it to
exit as well.
We don't want the tests to hang when the unmount fails.
