For FAT16/32 and XFS file systems clearing the label uses different
command options and code path in file system specific ::write_label()
method. Therefore extend this unit test to also test clearing the
label.
During review and testing of this patchset it was discovered that using
GParted to set a new UUID on a FAT16 or FAT32 file system that there was
a new unwanted side effect of clearing the label.
Add unit test to cover this error scenario. It does the following:
1. Creates a file system with a known label;
2. Writes a new UUID;
3. Reads the label and confirms it matches the initial label.
This new unit test captures the fault like this:
$ ./test_SupportedFileSystems --gtest_filter='*CreateAndWriteUUIDAndReadLabel*'

should be displayed as active or not in GParted.

The GitLab CI ubuntu_test job has occasionally been failing like this,
perhaps once every few weeks or so.

[----------] 1 test from My/SupportedFileSystemsTest (17 ms total)
Turns out there are 2 bugs in resier4progs. One causes debugfs.reiser4
to report a null UUID if the first byte of the UUID happens to be zero
[1], and the other cases mkfs.resier4 to write a corrupted UUID,
sometimes a null (all zeros) UUID [2].
There is a 1 in 256 chance of getting a null UUID [2] when creating and
reading a reiser4 file system, hence the occasional failure of the CI
job. The centos_test job isn't affected because CentOS doesn't have the
reiser4progs package.
Fix this by detecting when reiser4 reports a null UUID and assign a
dummy UUID to make the test pass. This does mean that there is a 1 in
256 chance of not detecting a true failure. However that still means
there is a 255 in 256 chance of detecting a true failure. That's good
odds. When a null UUID is detected for a reiser4 file system the test
output looks like this:
[ RUN ] My/SupportedFileSystemsTest.CreateAndReadUUID/reiser4

See how the test_BlockSpecial fixtures are getting major=0 and minor=0
for the block special devices they are testing with. This is happening
because there aren't any entries in /dev for those disks and partitions
listed in /proc/partitions. Assume that Docker in GNOME GitLab has
changed and that unneeded and unwanted devices in /dev are no longer
being created inside images.
In the test CI jobs execute new script, tests/makedev.sh, to create just
the first two block special devices mentioned in /proc/partitions needed
by test_BlockSpecial.

So JFS is reporting 2472 unallocated sectors in a size of 524288 sectors
and NTFS is reporting 8 unallocated sectors in the same size. This
exact issue is already solved for GParted so that it doesn't show a
small amount of unallocated space by commits [1][2] from Bug 499202 [3].

Closes!49 - Add file system interface tests
File systems BTRFS, JFS, NILFS2 and XFS can only be resized while
mounted, but only root can mount file systems. Therefore these tests
fail. Also BTRFS resize uses 'btrfs filesystem show' to discover the
devid, which also fails as described in the previous commit message.
Note that root can mount a file system image directly, but that it
implicitly creates loop device:
# truncate -s 256M test.img
# mkfs.xfs test.img
# mount test.img /mnt/1
# fgrep /mnt/1 /proc/mounts
/dev/loop0 /mnt/1 xfs rw,seclabel,relatime,attr2,inode64,noquota 0 0
# losetup -a
/dev/loop0: [64768]:35826659 (/root/test.img)
Therefore make these tests root only and require an explicit loop
device. Now these file system resize tests succeed as root and are
skipped as non-root.
Closes!49 - Add file system interface tests

Make the LVM2 PV tests require user root and use loop device over the

the image file. This makes the LVM2 PV tests pass when run as root, or
successfully skipped when run as non-root.

Closes!49 - Add file system interface tests
Replace directly using ext2 derived FileSystem interface class with
using the SupportedFileSystems class. This is a step in getting ready
for testing all the GParted file system interface classes in one go.
Closes!49 - Add file system interface tests
GParted_Core::FILESYSTEMS and ::FILESYSTEM_MAP and the methods that
query and manipulate them are self-contained. Therefore move them into
a separate SupportedFileSystems module.
Also having a single class maintaining all FileSystem interface objects
will make testing all the file system types much easier as there will be
no need to duplicate this functionality in the test.
Closes!49 - Add file system interface tests
Here are the errors reported in the deliberately broken
CreateAndReadLabel test from the previous commit message:
[ RUN ] ext2Test.CreateAndReadLabel
test_ext2.cc:311: Failure
Value of: m_partition.get_messages().empty()
Actual: false
Expected: true
Partition messages:
e2label: No such file or directory while trying to open /does_not_exist/test_ext2.img
Couldn't find valid filesystem superblock.
[ FAILED ] ext2Test.CreateAndReadLabel (77 ms)
Even though the test was deliberately broken by setting the wrong path
for the file system image and the e2label command failed, apparently
testing for the expected label still passed. What happened was that the
desired "TEST_LABEL" has to be in the Partition object and then the file
system was created. Then reading the file system label failed, however
"TEST_LABEL" was already set in the Partition object so it matched.
Reading the label is unique among the read actions of usage, label and
UUID as the others don't need to be set before the file system is
created. GParted doesn't encounter this issue because when refreshing
devices it creates new blank Partition objects and then performs the
read actions to populate them.
Fix by resetting the Partition object back to only containing basic
information before all the reading file system information tests, even
though it is only needed in the read label case. This also better
reflects how GParted works.
Now with the same deliberate brokenness the test also reports the label
does not match it's expected value:

Closes!49 - Add file system interface tests
The file system reading methods report errors into Partition messages
because they are used as part of the GParted refresh, rather than
reporting errors into OperationDetails used when applying operations.
Therefore test for no messages for success and print the messages on
failure.

the wrong file system image name produces this:

As seen in the first commit message, operation detail text is XML
encoded. This makes it harder to read, especially commands which often
have single quotes encoded as '. For example:
<b><i>mkfs.ext2 -F -L '' '/home/centos/programming/c/gparted/tests/test_ext2.img'</i></b>
Strip this encoding when printing the operation details. Now the same
example looks like:

Running test_ext2 in GitLab Continuous Integration environment fails like
this:
(test_ext2:6338): Gtk-WARNING **: 09:06:17.576: cannot open display:
Running main() from test_ext2.cc
Obviously the GitLab CI environment doesn't have an X11 display, but
unfortunately this test case code requires one.
Utils::execute_command() calls Gtk::Main::run() so requires a Gtk::Main
object constructing and therefore an X11 display, even though this
program never displays anything graphical. The call chain is:
main() test_ext2.cc
Gtk::Main::Main() gtkmm/gtk/src/main.ccg
Gtk::Main::init() [1]
gtk_init() gtk/gtk/gtkmain.c [2]
which exits with a non-zero exit status when the DISPLAY environment
variable is unset.
Looked at deriving from Gtk::Main class and writing a replacement init()
method which calls gtk_init_check() instead of gtk_init() but
Gtk::Main::instance_ is a private member so not accessible in a derived
class.
Tried using Glib::MainLoop instead of Gtk::Main, but that doesn't
initialise everything that Gtk::Main(), so the program crashes.
Therefore use xvfb-run [3][4] to run this test program against a virtual
X11 display when a real display isn't available. Coded execution of
xvfb-run into this test program so that it can simply be executed on the
command line like the other test programs, without having to remember to
run "xvfb-run ./test_ext2 ...".

[4] Using GTK without DISPLAY
https://stackoverflow.com/questions/11694278/using-gtk-without-displayCloses!49 - Add file system interface tests
This is the first step of adding testing of the derived FileSystem
interface classes which call the file system specific executables.
Rather than mocking command execution and returned output the tests run
the real commands, effectively making this integration testing.
Test case setup determines the file system supported actions using
get_filesystem_support() and individual tests are skipped if a feature
is not supported, just as GParted does for it's actions.
Each test creates it's own sparse image file and a fresh file system,
performs a test on one FileSystem interface call and deletes the image
file. This makes each test independent and allows them to run as a
non-root user, provided the file system command itself doesn't require
root. Errors reported for a failed interface call will include the
GParted OperationDetails, which in turn includes the file system
specific command used and stdout and stderr from it's execution.
For example, temporarily breaking the test code to create a 10 KiB image
file instead of 256 MiB one produces this:
$ ./test_ext2

Also as Utils:: and FileSystem::execute_command() are needed, this
requires linking with GParted_Core for GParted_Core::mainthread and
therefore with most of the non-UI classes in gpartedbin.

Was attempting to erase the wrong key "key-long" for the test. It
should be erasing "key-too-long". Fix this. Given that that line in
the test was to erase a non-existent key and confirm failure; the test
passed before with the wrong non-existent key, and still passes with the
right non-existent key. Clearly a cut and paste error as a result of
copying the previous LongPassword test when initially added in:

the string points to nothing and the test fails (It does not fail all

Use of Glib::thread_init() was deprecated in glibmm 2.32 [1]. The
oldest supported distributions have these versions:
Debian 8 glibmm 2.42.0
RHEL / CentOS 7 glibmm 2.56.0
SLES 12 glibmm 2.38.1
Ubuntu 14.04 LTS glibmm 2.39.93
Checking further the glibmm 2.32 reference manual says this about
Glib::thread_init() [2]:
Initializes the GLib thread system.
Deprecated:
Calling thread_init() is no longer necessary and no longer has any
effect.
However only some of the glibmm example programs had Glib::thread_init()
removed, others had it replaced by Glib::init() [3]. Again the glibmm
2.32 reference manual says this about Glib::init() [4]:
Initialize glibmm.
You may call this more than once. You do not need to call this if
you are using Glib::MainLoop or Gtk::Main, because they call it for
you.
GParted does call Gtk::Main and test_PipeCapture does call
Glib::MainLoop. Therefore just raise the minimum version to glibmm 2.32
and remove both calls to Glib::thread_init().

Replace the insert() method (which reports an error when inserting a
password with a key which already exists) with the store() method which
replaces or inserts the password depending on whether the key already
exists or not respectively. There is also an optimisation that nothing
is changed if the password to be replaced is the same as the one already
stored. The code in Win_GParted::open_encrypted_partition() is
simplified now it doesn't have to implement this pattern of behaviour
itself.
Bug 795617 - Implement opening and closing of LUKS mappings
Use private access into the PasswordRAMStore class to directly obtain
the address of the locked memory, rather than inferring it from the
address of the first stored password. This simplifies
PasswordRAMStoreTest::SetUpTestCase() and avoids encoding most of the
implementation knowledge that the first password will be stored at the
start of the protected memory.
Bug 795617 - Implement opening and closing of LUKS mappings
Test that all passwords are zeroed by PasswordRAMStore::erase_all(), the
same method as used in the PasswordRAMStore destructor.
Bug 795617 - Implement opening and closing of LUKS mappings
As noted in comments:
1) This is white box testing because it uses implementation knowledge
to look through the API to the internals of the password store.
2) It is not currently possible to test that the passwords are zeroed
when the store is destroyed.
However zeroing of memory is being tested when individual passwords
are erased.

1 FAILED TEST
Which in turn causes make check and make distcheck to fail.
Use directory /dev/disk/by-id/ instead as it always exists.
Make distcheck is failing like:

Make distcheck started failing like this with this commit:
f31808989a
Silence subdir-objects warning from automake 1.14 (#781978)
However, also need to be referring to source files from a sibling
directory like this from tests/Makefile.am:
test_BlockSpecial_SOURCES = test_BlockSpecial.cc ../src/BlockSpecial.cc
^^^^^^^
First introduced by this commit:
c37be28148
Add unit tests for BlockSpecial constructors and internal caching (#781978)
This failure, if not exactly common, has been seen a number of times
before. Using this hint from a GNU Automake forum post:
converting to subdir-objects
http://gnu-automake.7480.n7.nabble.com/converting-to-subdir-objects-td21724.html
"I had the same issue and wouldn't care unless Automake 1.15 started
to warn about "source file in a subdirectory". In my case 'bar.o' is
also built from 'foo/Makefile' so I decided to skip using 'bar.c' as
SOURCE and instead link in 'foo/bar.o'.

Cheers,

"
Fix by avoiding referring to source files from a sibling directory when
building the unit test programs, instead refer to object files instead.
Note that the automake subdir-objects option is still required to
silence the warning because of the use of source files in subdirectories
by lib/gtest/Makefile.am.
Bug 785308 - make distcheck fails with *.Po: No such file or directory
Test that binary data that happens to be the start of a multi-byte UTF-8
character but then contains a NUL byte is successfully read. The test
currently detects failure thus:
$ ./test_PipeCapture
...

Bug 777973 - Segmentation fault on bad disk
PipeCapture::OnReadable() has been almost completely re-written but this
test is still failing thus:
$ ./test_PipeCapture
...
[ RUN ] PipeCaptureTest.MinimalBinaryCrash777973
test_PipeCapture.cc:313: Failure
Expected: inputstr
Of length: 27

[ FAILED ] PipeCaptureTest.MinimalBinaryCrash777973 (0 ms)
...
The OnReadable() code specifically skips invalid bytes which aren't part
of valid UTF-8 characters, because they can't be displayed to the user.
The final C2 byte is the start of a multi-byte UTF-8 character, so on
it's own is invalid. Therefore PipeCapture skips it. Update expected
string accordingly. Now the test passes.
Bug 777973 - Segmentation fault on bad disk
Initialise capture string with sacrificial text before each test.
Existing tests confirm this is cleared first by checking the captured
string matches the input string.
Bug 777973 - Segmentation fault on bad disk
A user had a very corrupt FAT file system and fsck.fat was reporting
binary data in file names with errors. GParted crashed reading this
output. Boiled down the problematic fsck.fat output to a sample 27
bytes which still triggers a crash and created a test for it. The test
crashes test_PipeCapture program too.
$ ./test_PipeCapture
...
[ RUN ] PipeCaptureTest.MinimalBinaryCrash777973
Segmentation fault (core dumped)
$ echo $?
139
However it still produces a non-zero exit status and the autotools test
runner detects this so 'make check' still reports failure.
$ make check

Also ensure that the PipeCapture calls registered update callbacks and
that the data so far captured matches the leading portion of the input.
Bug 777973 - Segmentation fault on bad disk
Google Test string comparison asserts are only designed of C style
strings containing printable text of one or more lines with a
terminating NUL character. GParted is crashing when PipeCapture is
reading the binary file names being reported by fsck.fat from a very
corrupted FAT file system. Therefore need to be able to compare and
report differences of binary data stored in C++ std::string and
Glib::ustrings. Write a specific assertion to handle this.
Now these sample tests:
TEST_F( PipeCaptureTest, BinaryStringFailure )
{
inputstr = "AAAAAAAAAAAAAAAABBBBBBBBBBBBBBBBCCCCCCCCCCCCCCCC";
capturedstr = "AAAAAAAAAAAAAAAABBBBBBBBBBbbbb";
EXPECT_BINARYSTRINGEQ( inputstr, capturedstr.raw() );
}
TEST_F( PipeCaptureTest, LeadingBinaryStringFailure )
{
inputstr = "The quick brown fox jumps over the lazy dog";
capturedstr = "The quick brown fox\n";
EXPECT_BINARYSTRINGEQ( inputstr.substr( 0, capturedstr.raw().length() ),
capturedstr.raw() );
}
report failure like this:
$ ./test_PipeCapture
...

Bug 777973 - Segmentation fault on bad disk
Add test sending 1 MiB of ASCII test into PipeCapture to read. This
requires multiple reads and rewites through the pipe.
This is as much a check of the threading in the PipeCaptureTest class as
it is of PipeCapture itself. This is because a single thread might
block reading from a pipe waiting for itself to write to the pipe.
Deadlock. Hence the requirement to use a separate thread for reading
and writing.
