Mlabel sometimes writes uninitialised memory at the end of the label.
This causes mlabel, and therefore GParted, to display extra junk at the
end of the label. Depending on the bytes written GParted may also show
the following error on stdout:
(gpartedbin:18116): glibmm-CRITICAL **:
unhandled exception (type Glib::Error) in signal handler:
domain: g_convert_error
code : 1
what : Invalid byte sequence in conversion input
This is caused by a bug in mlabel, believed fixed in mtools 4.0.14.
Effects at least Fedora 14, RHEL/CentOS 6.x and Debian 6. (Use label
"1234567890" on Debian 6 to reproduce). Reproduction steps:
# mkdosfs -F16 /dev/sda7
mkdosfs 3.0.9 (31 Jan 2010)
# export MTOOLS_SKIP_CHECK=1
# mlabel ::123456 -i /dev/sda7
# mlabel -s :: -i /dev/sda7
Volume label is 123456~1t
It is not possible to detect which characters are junk so they can't be
trimmed. Instead just space pad labels so that at least newly written
labels aren't effected. (Fat labels are space padded on the disk by
definition anyway).
Bug #700228 - FAT16/32 labels are sometimes shown corrupted
There was virtually no difference between the separate modules for fat16
and fat32. Remove module fat32 and patch fat16 to serve both file
system subtypes. This is equivalent to what was previously done for
ext[234] by commit:
38dc55d49c
Combine duplicate code for ext[234]
Rename function to update_command_output() to better reflect that this
callback updates the UI with the latest output read from the command
being executed.
This makes more sense knowing a future change will add a separate
callback which parses the output read from the command and updates the
progress bar. This function should be named update_command_progress().
Rename the libsigc++ signals to signal_update and signal_eof to match
the naming used for signals in GParted.
fgrep 'sigc::signal' include/*.h
Also explicitly use the emit() method rather than using the object
operator(). This again is to match the convention in GParted and make
it more obvious what is happening.
fgrep '.emit(' include/*.h
Add xdg-su to list of possible programs used to acquire root
privileges in the gparted.desktop file.
Bug #699626 - Enable gparted.desktop to prompt for root on default
openSUSE installation
Add xdg-su to list of graphical switch-to-root programs to be
considered for gparted.desktop file.
The openSUSE GNU/Linux distribution includes the program xdg-su by
default for graphically prompting for root privilege.
This enhancement enables a user to compile and install gparted from
source code on openSUSE and have the gparted menu entry graphically
prompt for root privilege.

The autoconf check for the Gtk::Window::set_default_icon_name() method
was failing to detect its availability, but only on Ubuntu >= 11.10.
Turns out that the autoconf check incorrectly defined the link libraries
via the C++ flags variable CXXFLAGS, rather than the LIBS variable.
This resulted in the libraries being specified in the wrong order on the
command line. The test only failed when Ubuntu also added the
"--as-needed" flag to the linker by default [1] which required the
libraries to be correctly specified at the end of the command line.

This fixes commit:
a042107883
Only use Gtk::Window::set_default_icon_name method when available
Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
The previous commit missed one glibmm GSource wrapper in the form of the
io watch for the PipeCapture class. Convert this one to use glib
directly as well.
Bug #697727 - Segfault in livecd Gparted v 0.15.0-3 when copying
partition
Applications are moving away from storing icons in /usr/share/pixmaps,
instead preferring /usr/share/icons/hicolor/$SIZE/apps, so only install
the fallback icon when GParted requires it.
Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
On RHEL / CentOS 5.9 GParted couldn't set an icon as the
set_default_icon_name() method is not available. See commit [1] for
details.
Re-add the old set_icon_from_file() method as a fallback and re-install
a GParted pixmap as was used before commit [2].

Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
On RHEL / CentOS 5.9 GParted failed to run any external commands and
instead reported the following warnings to the terminal:
# src/gpartedbin
======================
libparted : 1.8.1
======================
Failed to change to directory '' (No such file or directory)
Failed to change to directory '' (No such file or directory)
Failed to change to directory '' (No such file or directory)
...
Utils::execute_command() and FileSystem::execute_command() passed a zero
length string for the working directory to
Glib::spawn_async_with_pipes() to mean don't change directory. Instead
glibmm just tried to change to the directory with a zero length name.
This was fixed with glibmm >= 2.21.2 released July 2009, however RHEL /
CentOS 5.9 only has glibmm 2.12.10.
Relevant glibmm fix:
Treat empty Glib::spawn*() working dir as unset
https://git.gnome.org/browse/glibmm/commit/?id=8a7805cbbe6d268e975669349beb4e82d971537d
Fix by simply specifying ".", the current working directory, as the
directory to change into before executing all commands.
Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
Glib::ustring::compose() method requires glibmm >= 2.16, but RHEL /
CentOS 5.9 only provides glibmm 2.12. Replace with String::ucompose()
as is used everywhere else in the code.
Add missing include for kill() and SIGINT declarations.
Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
Roughly HFSX is a case sensitive version of the HFS+ file system.
Parted reports such a file system as "hfsx" rather than "hfs+".
# mkfs.hfsplus -v "case insensitive hfs+" /dev/sda7
Initialized /dev/sda7 as a 1024 MB HFS Plus volume
# mkfs.hfsplus -s -v "case sensitive hfs+" /dev/sda8
Initialized /dev/sda8 as a 1024 MB HFS Plus volume
# parted /dev/sda print
...
Number Start End Size Type File system Flags

# blkid /dev/sda[78]
/dev/sda7: LABEL="case insensitive hfs+" TYPE="hfsplus"
/dev/sda8: LABEL="case sensitive hfs+" TYPE="hfsplus"
Make GParted recognise HFSX file system variants too.
Closes Bug #698876 - GParted fails to recognize HFS+ partition (possible
due to disabled journaling)
In some circumstances gparted would appear to scan forever if it
encountered a blank hard disk. This would happen if the timing of
events was right and gparted encountered a disk without a partition
table. The missing partition table would cause a call to the
exception handler, which could get stuck in a thread waiting position.
The problem was traced back to the ped_exception_handler
and a cond.signal() call missing the requisite mutex.lock() and
mutex.unlock() around the signal call.
Closes Bug #697518 - gparted scans forever blank disk in virtualbox
The glibmm GSource wrappers have a bug where they do not do
reference counting properly, and have a race condition where
the background thread can try to touch the source after the
main thread has already processed and destroyed it. This
results in writes to freed memory and sometimes this causes
crashes or other erratic behavior. Avoid using the glibmm
wrappers and use glib directly. See bug #561885 for details
of the glibmm bug.
Bug #697727 - Segfault in livecd Gparted v 0.15.0-3 when copying partition
For an absolutely full NTFS GParted doesn't show the file system usage
but instead shows a warning against the partition.
GParted was looking only for "resize at %d" to determine file system
used figure in the output from the ntfsresize command. Also handle
finding "ERROR: Volume is full" too to derive used figure.
