autoreconf: autopoint is needed because this package uses Gettext
This is because on CentOS 7 autopoint is provided by the gettext-devel
package which was installed as a requirement for intltool. Fix the
build by explicitly installing the package.
(On Alpine Linux the gettext-dev package is automatically installed and
on Ubuntu the autopoint package is automatically installed so those CI
images don't need to explicitly include the relevant package).
Closes!107 - Migrate from intltool to gettext translation
In the Alpine Linux 3.16 CI build job, file org.gnome.gparted.policy is
not translated with this warning:

This is because gettext's msgfmt doesn't have rules for what elements to
translate in .policy XML files. Add polkit-dev package to Alpine Linux
CI image to provide these files:
/usr/share/gettext/its/policy.its
/usr/share/gettext/its/policy.loc
Now the .policy file is translated successfully:

Closes!107 - Migrate from intltool to gettext translation
[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:
$ ./autogen.sh
...
autoreconf: running: /usr/bin/autoconf --force

...
Note that use of AM_GLIB_GNU_GETTEXT was deprecated in GLib 2.47.5
released 2016-01-18 [7]. Newer versions of GLib are included in the
oldest supported distributions:
Distro Package containing Version
glib-gettext.m4
Debian 10 libglib2.0-dev-bin 2.58.3
RHEL / CentOS 7 glib2-devel 2.56.1
Ubuntu 18.04 LTS libglib2.0-dev-bin 2.56.4
SLES 12 SP5 glib2-devel 2.48.2
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

Avoid having to manually maintain the list of excluded File System tests

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.

sum_devid_used = 239861760 + 436207616
= 676069376
sdb1 usage = 178749440 * 239861760 / 676069376
= 63418277
sdc1 usage = 178749440 * 436207616 / 676069376
= 115331163
Usage figures using the new calculation apportioning file system wide
usage according to device sizes:
# btrfs inspect-internal dump-super /dev/sdb1 | egrep 'total_bytes|^bytes_used'
total_bytes 4294967296
bytes_used 178749440
dev_item.total_bytes 2147483648
# btrfs inspect-internal dump-super /dev/sdc1 | egrep 'total_bytes|^bytes_used'
total_bytes 4294967296
bytes_used 178749440
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

devid 2 size 2147483648 used 436207616 path /dev/sdc1
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

Closes!105 - Update used btrfs file system commands, new minimum is
btrfs-progs 4.5
Until now GParted has run 'btrfs filesystem show' to read the file
system label. This has a number of issues and limitations:
1. Doesn't work on a file system image so can't be unit tested in the
GitLab CI test job where a loop device can't be created [1] or as a
non-root user.
2. Reported failed exit status 1 when successfully showing a mounted
btrfs, but only when using btrfs-progs v3.14 and 3.14.1 [2][3].
3. Failed to distinguish between label set to "none" and no label
reported as none, but only when mounted and with btrfs-progs v3.12
[3].
As non-root user run btrfs read label unit test:
$ tests/test_SupportedFileSystems --gtest_filter='*CreateAndReadLabel/btrfs'
...
[ RUN ] My/SupportedFileSystemsTest.CreateAndReadLabel/btrfs
test_SupportedFileSystem.cc:539: Skip test. Not root to be able to create required loop device
[ OK ] My/SupportedFileSystemsTest.CreateAndReadLabel/btrfs (0 ms)
Even as root, 'btrfs filesystem show' fails to work on an image file:
# truncate -s 256M /tmp/test.img
# mkfs.btrfs /tmp/test.img
# btrfs filesystem show /tmp/test.img
ERROR: not a valid btrfs filesystem: /tmp/test.img
# echo $?
1
# rm /tmp/test.img
Instead use 'btrfs filesystem label' to read the label. It also works
on an image file, the exit status is informative and output is just the
label followed by a new line character [4] so very simple to parse.
Error case:
$ truncate -s 256M /tmp/test.img

Run 'btrfs filesystem label' always passing the block device as this
works for both mounted and unmounted file systems. This is in
contrast to writing the label for a mounted btrfs where the mount
mount must be used [5].

Add unit testing of GParted exFAT interface (!30)
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.
Now fix the error with GParted clearing the label when setting a new
UUID on a FAT16/32 file system. Reproduce the issue on the command
line:
# mkfs.fat -F 16 -v -I -n TEST_LABEL /dev/sdb1
# mdir -f -i /dev/sdb1 ::/
Volume in drive : is TEST_LABEL
Volume Serial Number is 5D4C-6E6E
...
# mlabel -n -i /dev/sdb1 ::
# mdir -f -i /dev/sdb1 ::/
Volume in drive : has no label
Volume Serial Number is 77BB-A883
...
This was broken by commit "Fix writing FAT16/32 FS UUID on Alpine Linux
(!104)" earlier in this patchset, which included this comment:
"... Also drop the '-s' option
as showing the current label is unrelated to writing a new UUID."
It is not mentioned in the mlabel[1] manual page that option -s is
needed in order to avoid clearing the label when assigning a new UUID.
Anyway add the option back.

Closes!104 - Add Alpine Linux CI jobs and resolve label and UUID issues
with FAT16/32
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*'
...

This doesn't normally affect GParted because it uses blkid as first
choice to read file system UUIDs, only using file system specific
commands when blkid isn't available. Reproduce this on the command

by the POSIX strict getopt(3) on Alpine Linux. Apply the same fix of
moving the non-option argument to the end.

The mlabel.c source [1] uses getopt(3) to parse the command line
arguments. musl libc's [2] getopt(3) must be strictly POSIX compliant
[3][4] and stops reading options at the first non-option argument, '::'
in this case. Move the non-option argument to the end of the command
line and it works:
# mlabel -s -i /dev/sdb1 ::
Volume label is TEST_LABEL
Where as GNU Libc's getopt(3) [5] says that by default it reorders argv
eventually moving all non-option arguments to the end, hence why this
has worked on every Linux distribution using GNU Libc. This can be
broken on any Linux distribution using GNU Libc by enforcing strict
POSIX behaviour from getopt(3). For example on Fedora 36:
# mkfs.fat -F 16 -v -I -n TEST_LABEL /dev/sdb1
# export POSIXLY_CORRECT=1
# mlabel -s :: -i /dev/sdb1
Mtools version 4.0.39, dated April 10th, 2022
Usage: mlabel [-vscVn] [-N serial] drive:
# echo $?
1
# mlabel -s -i /dev/sdb1 ::
Hidden (2048) does not match sectors (63)
Volume label is TEST_LABEL
# echo $?
0
Fix by moving the non-option (image file drive specification) '::' to
the end of the mlabel command line.

There have been a number of GParted build issues [1][2] recently on
Alpine Linux because it uses musl libc [3] which is stricter to POSIX,
rather than the GNU C Library (glibc) which has numerous enhancements.
Glibc is used by most Linux distributions, including CentOS and Ubuntu
already used in the GNOME Continuous Integration jobs. So add a GParted
build job on Alpine Linux to catch these issues in future. Uses the
docker image of the latest Alpine Linux release.

When the CentOS 7 CI jobs were failing on a subset of the job runners
[1] during March to May 2022, the docker image would hang even before
the packages were fully installed so cat /proc/version and cat
/etc/os-release were never run. Move them to the first thing done in
the docker image.

Even though this is fixed the execution of configure as part of make
distcheck outputs this:
checking whether po/Makefile.in.in deletes intltool cache lock file... /usr/bin/grep: po/Makefile.in.in: No such file or directory
/usr/bin/sed: can't read po/Makefile.in.in: No such file or directory
/usr/bin/grep: po/Makefile.in.in: No such file or directory
no
make distcheck [1] performs a VPATH build with a read-only srcdir and
a separate writable build directory with files split between the two.
The relevant layout looks like:
./gparted-1.4.0-git/configure
./gparted-1.4.0-git/po/Makefile.in.in
./gparted-1.4.0-git/_build/sub/
And make distcheck runs configure like this:
cd ./gparted-1.4.0-git/_build/sub
../../configure --srcdir=../..
The file is ../../po/Makefile.in.in in this case, so not found by the
existing check. A simple investigation technique is to run make
distcheck, kill it shortly after configure completes and examine the
build tree. Definitely before make distcheck completes successfully and
deletes everything.
Fix by using $srcdir prefix to access the file. Also handle the case of
po/Makefile.in.in not existing, although this doesn't now occur in the
scenario fixed by this commit. And only patch the file if it's
writable, another case that doesn't occur in this scenario.
Relevant output line from configure run by make distcheck now looks
like:
checking whether po/Makefile.in.in deletes intltool cache lock file... yes

This was picked up by the GitLab ubuntu_test CI job after the Ubuntu

intltool >= 0.51.0-5.1 [1][2][3], first included in Ubuntu 22.04 LTS.
The pending proposed fix is to also delete the left behind
.intltool-merge-cache.lock along with the associated cache file itself
in the intltool provided Makefile.in.in [4].
Applying a fix to the GitLab ubuntu_test CI job does nothing for fixing
it for us maintainers on our distributions. po/Makefile.in.in is not
part of the GParted git repository, instead it is copied from
/usr/share/intltool/Makefile.in.in by ./autogen.sh -> gnome-autogen.sh
-> intltoolize --force --copy --automake. Add a configure check which
patches po/Makefile.in.in as needed. This will fix it for those
building from git, and be a harmless check for those building from a tar
release. Configure output line looks like:
