...and add tests for checking that gocryptfs.diriv
does not get created.
The main "integration_tests" package has become quite
big and convoluted over time.
This small separate package should make writing tests
for "-plaintextnames" easier.
As seen in "fusefrontend: fix PlaintextNames versions of Mkdir, Rmdir",
we need more of them.
There is no need to test that deprecated command-line options
produce an error. I trust the flags package.
Also split the example_filesystem helper functions into a
separate file.
The v0.6-plaintextnames example FS lacks the GCMIV128 feature
flag, is no longer mountable and can no longer be used for testing.
Add a new "-plaintextnames" filesystem created by gocryptfs v0.7.
There have been no format changes to "-plaintextnames" since then.
Also, capture all stderr and stdout but pass "-q".
This way we get to see error messages if there are any, or
spurious output when there should be none due to "-q".
Mounts two gocryptfs filesystems, "ping" and "pong" and moves the
linux-3.0 kernel tree back and forth between them.
When called as "pingpong-rsync.bash" it uses "rsync --remove-source-files"
for moving the files, otherwise plain "mv".
We (actually, go-fuse) used to call Chown() instead of Lchown()
which meant that the operation would fail on dangling symlinks.
Fix this by calling os.Lchown() ourself. Also add a test case
for this.
Running these tests from integration_tests' TestMain() was awkward
because they were run twice with unchanged settings.
integration_tests tests everything with OpenSSL and with native
Go crypto, but this does not take affect for the example filesystems.
To make this work, test_helpers is also split into its own package.
