This is the final piece which enables GParted to pass the LUKS
passphrase when resizing an open LUKS encryption mapping when
'cryptsetup resize' will prompt for it.
Closes#59 - Resize of LUKS2 encrypted file system fails with "Nothing
to read on input"
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
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
Running main() from test_ext2.cc

1
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.
Closes!49 - Add file system interface tests
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.

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'.
http://dev.thep.lu.se/svndigest/changeset/1581
Cheers,
Peter
"
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
On CentOS 6, with glib/glibmm 2.28, running the tests fails thus:
$ ./test_PipeCapture
Running main() from gtest_main.cc
[==========] Running 4 tests from 1 test case.
[----------] Global test environment set-up.
[----------] 4 tests from PipeCaptureTest

GLib-ERROR **: The thread system is not yet initialized.
aborting...
Aborted (core dumped)
For glib before version 2.32, the threading system must be explicitly
initialised with a call to g_thread_init(), or the Glibmm
Glib::thread_init() equivalent to prevent this error.
Deprecated thread API, g_thread_init()
https://developer.gnome.org/glib/stable/glib-Deprecated-Thread-APIs.html#g-thread-init
Do this by providing our own main() which also initialises the Glib
threading system, rather using and linking in the Google Test provided
main().
Bug 777973 - Segmentation fault on bad disk
So far just tests sending 0 bytes and a few ASCII bytes into a pipe and
that they are read correctly by the PipeCapture class.
Bug 777973 - Segmentation fault on bad disk
So far only includes tests of the construction of BlockSpecial objects
and the interaction with the internal cache used to reduce the number of
stat(2) calls. Tests have been designed to be runable by non-root users
and assume as little as possible about the environment by discovering
used block device names and symbolic link name.

make: *** [distcheck] Error 1
What is happening is that distcheck [1] performs a VPATH build which
uses separate read-only source and read-write build trees. Shipped
source files, such as .h and .cc, are located in the source tree and the
built files, such as .o and .la, are compiled into the build tree. In
this case the absolute path to libgtest_main.la is specified using
$(top_srcdir) for the source tree, rather than $(top_builddir) for the
build tree, hence the cannot find file type error. This error doesn't
occur when just performing a 'make check' because that builds in the
source tree so $(top_builddir) is the same as $(top_srcdir).
Fix by correctly specifying the absolute path to the libgtest*.la files
using $(top_builddir).
[1] Automake Manual, 14.4 Checking the Distribution
https://www.gnu.org/software/automake/manual/automake.html#Checking-the-Distribution
Note that for VPATH builds the Automake Manual [2] also recommends using
a pair of -I options to specify header files are found in both the build
and source trees, something like:
AM_CPPFLAGS = -I$(top_builddir)/some/subdir -I$(top_srcdir)/some/subdir
This is unnecessary for GParted as all header files are shipped as part
of the source archive and no header files are created as part of the
build process. Therefore adding -I options specifying $(top_builddir)
include directories would just be specifying empty or non-existent
include directories in the build tree.
