This is because the udevadm command is not found and so settle_device()
waits for 10 seconds in this call chain:
erase_filesystem_signatures()

Install udevadm command into the Alpine Linux CI job docker image to fix
this. Now it's on a par with the time taken in the other distro CI test

Closes#220 - Format to Cleared not clearing "pdc" ataraid signature
Move common testing code which doesn't need linking with GParted objects
into the common module. Move the remaining common code used to print
GParted objects using the insertion operator (operator<<) into the
insertion_operators module. Split the common code like this so that the
operator<<(std::ostream&, const OperationDetail&) function is not
included in test_PipeCapture and it is not forced to link with all the
non-UI related GParted objects.
The Automake manual provides guidance that when a header belongs to a
single program it is recommended to be listed in the program's _SOURCES
variable and for a directory only containing header files listing them
in the noinst_HEADERS variable is the right variable to use [1].
However the guidance doesn't cover this case for common.h and
insertion_operators.h; header files in a directory with other files and
used by multiple programs. So just because we have gparted_core_OBJECTS
(normal Makefile, not Automake special variable) listing objects to link
with, choose to use noinst_HEADERS Automake variable to list needed
headers.
[1] GNU Automake manual, 9.2 Header files
https://www.gnu.org/software/automake/manual/html_node/Headers.html
"Usually, only header files that accompany installed libraries
need to be installed. Headers used by programs or convenience
libraries are not installed. The noinst_HEADERS variable can be
used for such headers. However, when the header belongs to a
single convenience library or program, we recommend listing it
in the program's or library's _SOURCES variable (see Defining
program sources) instead of in noinst_HEADERS. This is clearer
for the Makefile.am reader. noinst_HEADERS would be the right
variable to use in a directory containing only headers and no
associated library or program.
All header files must be listed somewhere; in a _SOURCES
variable or in a _HEADERS variable. Missing ones will not
appear in the distribution.

Closes#220 - Format to Cleared not clearing "pdc" ataraid signature
Initially just testing erasing of Intel Software RAID signatures.
Chosen because it was expected to work, but turned out not to be true in
all cases.
The code needs to initialise GParted_Core::mainthread, construct
Gtk::Main() and execute xvfb-run because of this call chain:
GParted_Core::erase_filesystem_signatures()
GParted_Core::settle_device()
Utils::execute_command ("udevadm settle ...")
status.foreground = (Glib::Thread::self() == GParted_Core::mainthread)
Gtk::Main::run()
This was also needed when testing file system interface classes as
discussed in commits [1][2].

mkfs: stop allowing tiny filesystems
Refuse to format a filesystem that are "too small", because these
configurations are known to have performance and redundancy problems
that are not present on the volume sizes that XFS is best at
handling.
Specifically, this means that we won't allow logs smaller than 64MB,
we won't allow single-AG filesystems, and we won't allow volumes
smaller than 300MB.
Increase the default unit test file system image size from 256 MiB to
256+64 = 320 MiB to avoid this error.

GParted's check operation is a check and if possible repair. For most

The code was overly complicated in how it converted to the 32-bit little
endian on-disk representation of the Hidden Sectors field. It did:
1. Formatted the partition start sector as a hexadecimal string.
2. Padded it to 8 digits.
3. Reversed pairs of digits.
4. Converted pairs of hexadecimal digits to bytes of binary data.
5. Wrote the 4 bytes of binary data to the Hidden Sectors field.
There is no need for all this string manipulation to convert to a 32-bit
little endian value. Just do this:
1. Truncate (signed 64-bit) partition start sector to 32-bit.
2. Convert from host native to little endian.
3. Write as 4 bytes of binary data to the Hidden Sectors field.
The code also ignores write errors. ofstream.write() only copies the
data into an in process buffer [1] and the data is not passed to the OS
to write to the open file handle until ofstream.close() [2] is called.
However the status of close() was not checked so a failure of the OS to
perform the write would go unreported.
In the case of a failure providing the user with a command line to set
the Hidden Sectors field is excessive. Updating the Hidden Sectors is
no more or less likely to fail than for any other storage manipulation
action. For example GParted doesn't provide command line instructions
to update a partition size if a libparted call fails. Therefore remove.
Rewrite the code to resolve the above issues and lay it out using
if-operation-fails-return-early pattern.

Overview of what is happening is that GParted_Core::update_bootsector()
is attempting to set the Hidden Sectors [1] field in the NTFS Partition
Boot Sector (PBS) to the start sector of the newly copied /dev/loop0p2
partition. But the sector number is greater than will fit in a 32-bit
unsigned integer, which the code doesn't handle.
Specifically the code prints the sector number as a hexadecimal number
into string 'hex'. As the target partition starts at exactly 2 TiB then
hex="100000000" (9 hexadecimal digits long). Next:
hex.insert(0, 8 - hex.length(), '0');
is meant to pad the beginning of the 'hex' string with '0's to make the
string 8 character long. But the string is already 9 character long so
8 - 9 is -1 which as unsigned integral type size_t [2] is 2^64-1. So
insert() is trying to insert 18446744073709551615 '0's at the start of
the 'hex' string! Hence the crash.
mkntfs refuses to accept an explicit partition start sector of 2^32 or
larger:
# mkntfs -Q --partition-start 4294967296 /dev/loop0p2
Invalid partition start sector. Maximum is 4294967295 (2^32-1).
# echo $?
1
When mkntfs can't determine the drive geometry and partition offset, as
is the case on loop devices or the partition start sector is 2^32 or
larger, then mkntfs writes zero into Hidden Sectors:
# mkntfs -Q /dev/loop0p1
The partition start sector was not specified for /dev/loop0p1 and it could not be obtained automatically. It has been set to 0.
...
To boot from a device, Windows needs the 'partition start sector', ...
Windows will not be able to boot from this device.

Remove mention of intltool as it's now unused.
Add polkit to the list of dependencies to build GParted from source as
gettext always explicitly translates the org.gnome.gparted.policy file.
Add polkit-devel and gettext-devel packages to the packages needing
installing on various distributions to get the gettext translation rules
for .policy files and the autopoint build tool installed.
(Distributions such as Debian and Ubuntu split the packages differently.
Gettext translation rules for .policy files are in the base policykit-1
package and the autopoint tool is in the autopoint package which I
assume is always installed as part of the development tool set. Hence
no change to the command to install dependent packages on these
distributions. See the earlier commit messages for more details).

[0] GNOME Goal: Gettext Migration
https://wiki.gnome.org/Initiatives/GnomeGoals/GettextMigration
This goal from 2016 is to migrate away from using intltool to help
translate especially GNOME application related files, and instead use
gettext directly now that gettext can handle a lot more file formats
[1][2][3].
The GNOME Goal: Gettext Migration [0] says:
"With gettext 0.19.8, there is really no need anymore to use
intltool or GLib's dated gettext glue (AM_GLIB_GNU_GETTEXT and
glib-gettextize)."
This version or later of gettext is available in the oldest supported
distributions except for SLES 12:
Distribution EOL gettext -V
Debian 10 2022-Aug 0.19.8.1
RHEL / CentOS 7 2024-Jun 0.19.8.1
Ubuntu 18.04 LTS 2023-Apr 0.19.8.1
SLES 12 SP5 2024-Oct 0.19.2 [4][5]
As SLES 12 SP5 doesn't contain GParted and SLES 15 contains GParted
0.31.0 [6] loosing the ability to compile future GParted 1.5 release on
SLES 12 SP5 is acceptable.
Additionally the use of intltool and the associated GLib provided macro
AM_GLIB_GNU_GETTEXT was the source of the remaining warnings from
autoconf 2.71 seen in Fedora 36 and Ubuntu 22.04 LTS about the use of
obsolete macros:

Therefore perform the migration described in the GNOME wiki documents
[0][1]. This involves:
1. Replacing the macros used in configure.ac;
2. Copying Makevars.template to po/Makevars and setting
PO_DEPENDS_ON_POT and DIST_DEPENDS_ON_UPDATE_PO to "no";
3. Replace @INTLTOOL_*@ macros in Makefile.am with rules to use gettext
to directly translate the relevent GNOME application files;
4. Removing (_) underscore marking translation prefixes from XML tags in
GNOME application files as gettext understands which tags of which
files need translating.
For reference are these commits in projects GNOME-System-Monitor [8],
Reversi [9] and Evince [10] making the same transition.
At this point "./autogen.sh && make" succeeds, at least on Ubuntu which
provides the instructions gettext needs to correctly translate .policy
files by default. These:
/usr/share/gettext/its/polkit.its
/usr/share/gettext/its/polkit.loc
are included in the base policykit-1 package.

Autoconf 2.71 on Fedora 36 and Ubuntu 22.04 LTS has started reporting
a number of warnings about configure.ac containing obsolete macros. One
of them is this:
$ ./autogen.sh
...
Processing ./configure.ac
configure.ac:17: warning: The macro `AC_PROG_LIBTOOL' is obsolete.
configure.ac:17: You should run autoupdate.
m4/libtool.m4:99: AC_PROG_LIBTOOL is expanded from...
configure.ac:17: the top level
...
AC_PROG_LIBTOOL is deprecated and the replacement is LT_INIT [1].
LT_INIT is available in all supported distributions, for example RHEL /
CentOS 7 has libtool 2.4.2 with LT_INIT defined in
/usr/share/aclocal/libtool.m4 serial 57. The last known distribution
without LT_INIT was RHEL / CentOS 5 [2].
Update accordingly.

Avoid having to manually maintain the list of excluded File System tests
in the GitLab Docker CI image. Scan the unit test source extracting
those tests marked with SKIP_IF_NOT_ROOT_FOR_REQUIRED_LOOPDEV_FOR_FS()
to automatically construct the setting for the GTEST_FILTER environment
variable.
Closes!105 - Update used btrfs file system commands, new minimum is
btrfs-progs 4.5
Now that reading btrfs usage, UUID and label can be performed on a file
system image remove the need for a loop device for the relevant unit
tests.
Closes!105 - Update used btrfs file system commands, new minimum is
btrfs-progs 4.5
GParted has been using 'btrfs filesystem show' to report file system
usage but that doesn't work on a file system image so doesn't work in a
GitLab CI test job, as discussed earlier in this patchset.
There is 'btrfs inspect-internal min-dev-size' but:
1. That only works on a mounted file system and GParted isn't going to
mount an unmounted file system just to query it's used space, so by
extension won't work on image files.
2. It reports a figure which is almost the same as the chunk usage of
the device within the btrfs file system. However if some files have
been deleted leaving chunks partially used, then 'btrfs filesystem
resize' will successfully shrink a btrfs smaller than the reported
minimum device size.
And there is also 'btrfs filesystem usage' but that also only works on a
mounted file system.
So instead use 'btrfs inspect-internal dump-super' to report some of the
figures previously obtained from 'btrfs filesystem show'. For example
for a single device btrfs in an image file:
$ truncate -s 256M /tmp/test.img
$ mkfs.btrfs /tmp/test.img
$ btrfs inspect-internal dump-super /tmp/test.img | egrep 'total_bytes|bytes_used|sectorsize|devid'
total_bytes 268435456
bytes_used 114688
sectorsize 4096
dev_item.total_bytes 268435456
dev_item.bytes_used 92274688
dev_item.devid 1
Comparing with results from 'btrfs filesystem show' for the same file
system, after adding a loop device to allow 'btrfs filesystem show' to
succeed:
$ su -
# losetup --find --show /tmp/test.img
# btrfs filesystem show --raw /dev/loop0
Label: none uuid: 32a1eb31-4691-41ae-9ede-c45d723655a3
Total devices 1 FS bytes used 114688
devid 1 size 268435456 used 92274688 path /dev/loop0
This does bring a forced change in the calculation which affects multi-
device btrfs file systems. 'btrfs filesystem show' provided chunk
allocation information per device ("used" figure for each "devid"). The
file system wide used bytes ("FS bytes used") was apportioned according
to the fraction of the chunk allocation each device contained. However
'btrfs inspect-internal dump-super' doesn't provide chunk allocation
information for all devices, only for the current device
("dev_item.bytes_used"). Instead the calculation now has to apportion
the file system wide used bytes ("bytes_used") according to the fraction
of the size of the current device ("dev_item.total_bytes") within the
total size ("total_bytes").
This can't make any difference to a single device btrfs file system as
both fractions will be 1. It only affects how the file system wide used
bytes is distributed among multiple devices.
As an example to see the difference between calculation methods, create
a 2 GiB btrfs taking the defaults so getting duplicated metadata and
single data. Add another 2 GiB partition and populate with some files.

= 63418277
sdc1 usage = 178749440 * 436207616 / 676069376
= 115331163

usage according to device sizes:
# btrfs inspect-internal dump-super /dev/sdb1 | egrep 'total_bytes|^bytes_used'
total_bytes 4294967296

# btrfs inspect-internal dump-super /dev/sdc1 | egrep 'total_bytes|^bytes_used'

dev_item.total_bytes 2147483648
sdb1 usage = 178749440 * 2147483648 / 4294967296
= 89374720
sdc1 usage = 178749440 * 2147483648 / 4294967296
= 89374720
Both calculation methods ignore that btrfs allocates chunks at the
volume manager level. So when fully compacted the last chunk for
metadata and data for each storage profile (RAID level) will be
partially filled and this is not accounted for.
Also for multi-device btrfs file systems the new calculation provides
different results. However given that shrinking a device in a multi-
device btrfs file system can and does relocate extents to other devices
(redundancy requirements of chunks permitting) it's minimum size is
virtually impossible to calculate and may not restrict how small the
btrfs device can be shrunk anyway. If it turns out that this new
calculation causes problems it's been made a separate commit from the
previous commit for easier reverting.
Closes!105 - Update used btrfs file system commands, new minimum is
btrfs-progs 4.5
'btrfs filesystem show' only used to report rounded human readable size
figures. Therefore the actual figure could have been anywhere within
the rounding limit. GParted also applied a heuristic to snap the file
system size figure to the partition size if the partition size was
within the rounding limit of the reported file system size [1].
btrfs-progs v4.1 added the --raw option to print the figures in bytes
[2][3][4].
# btrfs filesystem show --raw /dev/sdb1

Since the oldest supported distributions now use btrfs-progs v4.5.3 and
later (see the distribution End-of-Life table in the previous commit
message), unconditionally use this to get accurate figures.

GParted so far uses 'btrfs filesystem show' to read the file system
UUID. But this doesn't work on a file system image so doesn't work in
the GitLab CI test jobs, as discussed in the earlier commit "Use btrfs
filesystem label to read the FS label (!105)".
$ truncate -s 256M /tmp/test.img
