Change the names, and sence, of the Autoconf and Automake definitions
used to control building of the help documentation. Reasons are:
(1) Switch from negative to positive statements which are more natural

(2) Insert HELP in the names from *_DOC to *_HELP_DOC as they control
building of the documentation in the help subdirectory, not the
manual page in the doc directory.

Bug #734076 - Autodetect parted online partition resizing capability
Add static member function GParted_Core::is_dev_mounted() so that other
modules can determine if a particular partition contains a mounted file
system or not.
Make it a static member function so that it can be called without
needing the gparted_core object. Extend to make the group of
manipulated variables (mount_info, fstab_info) and manipulating
functions (init_maps(), read_mountpoints_from_file(),
read_mountpoints_from_file_swaps(), get_all_mountpoints()) static too.

In the Create Partition Table dialog display the entries in the combobox
in order.
Previously the default of MSDOS or GPT was moved to the first item in
the combobox. Now the partition table types remain in order with just
either MSDOS or GPT being selected as as the default as required.
The partition table types are displayed in the order supplied by
libparted, which is alphabetic except with "loop" last.
Bug #711098 - Default partition table can not handle > 2 TiB disks
MSDOS partition table is limited to addressing 2^32 sectors, limiting
disks using 512 byte sectors to 2 TiB in size. Fdisk reports the
following warning on disks 2 TiB and larger.
# truncate -s 2T /var/tmp/loop-2T
# losetup /dev/loop0 /var/tmp/loop-2T
# fdisk /dev/loop0
WARNING: The size of this disk is 2.2 TB (2199023255552 bytes).
DOS partition table format can not be used on drives for volumes
larger than (2199023255040 bytes) for 512-byte sectors. Use parted(1) and GUID
partition table format (GPT).
(Fdisk arguably reports this warning one sector too early. Anyway for
safety and consistency GParted will use this limit too). Continue to
use MSDOS as the default partition table type for disks smaller than 2
TiB and use GPT as the default for disks 2 TiB and larger. This
maximises compatibility.
Also remove the advanced expander and always show the partition table
list box.
Bug #711098 - Default partition table can not handle > 2 TiB disks
Many file systems are capable of growing while mounted, and a few can
even shrink. This support must be explicitly enabled at configure time
with the --enable-online-resize flag and depends on a patched libparted.
Also requires kernel >= 3.6 for partition resizing, even if the
partition is in use (BLKPG_RESIZE_PARTITION).
Thanks to Mike Fleetwood for double check mark idea instead of a second
column to show the online grow/shrink.

Step 3 of 3:
Now that all label widgets are created with ALIGN_LEFT and ALIGN_CENTER
alignment remove the x_align and y_align parameters from mk_label() and
always use this alignment. Also specify this alignment via floats
rather than enumerators, one of which was deprecated.
Bug #652044 - uses deprecated APIs
Step 2 of 3:
ALIGN_RIGHT was only used for the size figures in the GParted > Devices
device selector with radio buttons. Change to ALIGN_LEFT and adjust the
widget packing to maintain appearance.
Bug #652044 - uses deprecated APIs
Gtkmm release 2.24 in February 2011 deprecated the use of these
alignment enumerators superseding them with:
Deprecated enumerator Use instead
Gtk::ALIGN_LEFT Gtk::ALIGN_START
Gtk::ALIGN_RIGHT Gtk::ALIGN_END
Gtk::ALIGN_TOP Gtk::ALIGN_START
Gtk::ALIGN_BOTTOM Gtk::ALIGN_END
gtkmm: gtkmm Enums and Flags [2.24]
https://developer.gnome.org/gtkmm/2.24/group__gtkmmEnums.html
The deprecated alignment enumerators were only used in the creation of
Gtk::Label widgets by method Utils::mk_label(). In all but three cases
the alignment was left, center. So make all labels with alignment left,
center and then stop using the deprecated enumerators.
Step 1 of 3:
ALIGN_TOP was only used for these 2 labels:
"Path:" text in View > Device Information;
"Path:" text in Partition > Information.
Use of ALIGN_TOP makes no difference to these labels so just change to
ALIGN_CENTER.
Bug #652044 - uses deprecated APIs
It was possible to make GParted crash by adding a label, check or new
UUID operation and then applying the operation before the view of
pending operations had finished fully opening. The operation would be
successfully applied but GParted would crash afterwards.
The fault was that Add_Operation() still enabled the Undo and Apply
buttons and processed the GTK event loop before merging the list of
pending operations. Faulty code flow went like this:
activate_*()
Add_Operation()
Add operation to the operations[] vector
Enable Undo and Apply buttons
Refresh_Visual()
Process GTK event loop
Process Apply button callback applying operations,
refreshing display and clearing operations[] vector
Merge operations in the operations[] vector
<< Core dump here >>
Merge_Operations()
Refresh_Visual()
This faulty code flow came about when merging of operations was added
and it didn't appreciate that the operations[] vector could have been
processed and cleared by Add_Operations() before the merge step.
Relevant commit:
b10349ae37
Merge overlapping operations (#438573)
Fragment of code in the label operation case:
2454 void Win_GParted::activate_label_partition()
2455 {
...
2472 Add_Operation( operation ) ;
2473
2474 // Verify if the two operations can be merged
2475 for ( unsigned int t = 0 ; t < operations .size() - 1 ; t++ )
2476 {
2477 if ( operations[ t ] ->type == OPERATION_LABEL_PARTITION )
2478 {
2479 if ( Merge_Operations( t, operations .size() - 1 ) )
2480 break;
2481 }
2482 }
Commentary in the crashing label operation case:
2472 The pending operation was already applied when Add_Operation()
returned resulting in the operations[] vector being cleared
setting its size to 0.
2475 The return type of operations.size() is an unsigned integral, so
the upper limit of the for loop is t < 0UL - 1. Assuming a
32-bit machine that's t < 4294967295.
2477 operations[] vector is access from out of bounds offset 0
upwards until unallocated memory is accessed resulting in a core
dump.
Fix this by not enabling the Undo and Apply buttons and processing the
GTK event loop until after merging of operations has been performed.
Fixed code flow goes like this:
activate_*()
Add_Operation()
Add operation to the operations[] vector
Merge operations in the operations[] vector
Merge_Operations()
show_operationslist()
Enable Undo and Apply buttons
Refresh_Visual()
Process GTK event loop
Process Apply button callback applying operations,
refreshing display and clearing operations[] vector
Not allowing the operations list to be process until after the merge
step is the be correct ordering. This also prevents the new operation
from flashing up in the operations list and then immediately
disappearing if merged. In the case of adding the first operation,
delaying enabling the Undo and Apply buttons is enough as the buttons
were previously disabled preventing the operation being applied before
the merge. In the case of adding further operations, processing of the
GTK event loop must also be delayed until after the merge to prevent the
operations being applied before the merge. Although that window of
opportunity would only be microseconds.

fully displayed

GParted fails to compile on RHEL/CentOS 5.9 because it doesn't provide
the Gtk::Window::set_default_icon_name() method. The "gtkmm GTK::Window

in gtkmm >= 2.6, however it is not available in RHEL/CentOS 5.9 with
gtkmm 2.10.

Win_Gparted and Dialog_Progress were creating threads to perform most
functions in the background. Most of the time, the only reason the
threads blocked was to execute an external command. The external command
execution has been changed to spawn the command asynchronously and wait
for completion with a nested main loop. While waiting for completion,
the pipe output is captured via events. In the future, this will allow
for it to be parsed in real time to obtain progress information.
Those tasks in GParted_Core that still block now spawn a background thread
and wait for it to complete with a nested main loop to avoid hanging the
gui.
Part of Bug #685740 - Refactor to use asynchronous command execution
Win_Gparted and Dialog_Progress were looping on Gtk::Main::events_pending()
and iteration() with usleeps in between. Use a full mainloop instead and
a proper timeout to trigger pulsebar updates instead of usleeps.
Part of Bug 685740 - Refactor to use asynchronous command execution
Use of these functions is depreciated and making gtk calls in a background
thread still sometimes causes deadlocks or crashes. Change ped exception
handler to instead use an idle function to force the main thread to display
the dialog box.
Part of Bug 685740 - Refactor to use asynchronous command execution
GParted doesn't notice when a file system label is changed to blank.
GParted first calls the file system specific read_label() method. When
the label is blank read_label() correctly sets partition.label to the
zero length string. Second GParted_Core::set_device_partitions() treats
the zero length string to mean that the label is unset and calls
FS_Info::get_label() to retrieve it from the cache of blkid output.
Blkid also doesn't notice when the file system label has been changed to
blank so reports the previous label. Hence GParted displays the
previous file system label.
Fix by making label a private member variable of the class Partition and
providing access methods set_label(), get_label() and label_known()
which track whether the label has been set or not. This only fixes the
fault for file systems which use file system specific commands to read
the label and when these tools are installed. Otherwise GParted uses,
or has to fall back on using, the buggy blkid command to read the file
system label.
NOTE:
Many of the file system specific read_label() methods use a tool which
outputs more than just the label and use Utils::regexp_label() to match
leading text and the label itself. If the surrounding text changes or
disappears altogether to indicated a blank label, regexp_label() doesn't
match anything and returns the zero length string. This is exactly
what is required and is passed to set_label() to set the label to blank.
Bug 685656 - GParted doesn't notice when file system label is changed to
blank
Active LVM2 PVs have the partition class busy member set in
GParted_Core::set_device_partitions() just as mounted file systems do.
This is a basic requirement for GParted so that it only manipulates
partitions and contained file systems when they are not in use.
Rename functions and a variable to use a generic term for the menu item
which changes the busy state of partitions now that it also activates
and deactivates LVM2 Physical Volumes as well as mounting and unmounting
file systems and enables and disables swap partitions.
The new delete non-empty LVM2 Physical Volume warning dialog uses
Gtk::MessageDialog::get_message_area() in the display of Volume Group
members. This function was new in gtkmm 2.22, released September 2010,
which is not available in a number of current distributions including:
Unbuntu 10.04 LTS, RHEL 6.3, SLES 11-SP2, Debian 6.0.
Implement fallback method to display the VG name and member PVs in the
warning dialog for when get_message_area() is not available.
Bug #670171 - Add LVM PV read-write support
When attempting to delete a non-empty LVM2 Physical Volume (one which is
still a member of a Volume Group) display a warning dialog which
includes the VG name and a list of the PV members to allow the user to
make an informed choice whether to go ahead and perform the deletion or
cancel to the operation. This dialog is displayed when a partition
containing a PV is being deleted or being overwritten by being
reformatted or pasted into.
Bug #670171 - Add LVM PV read-write support
In the Partition menu enable activation / deactivation of the LVM2
Volume Group of which the Physical Volume is a member.
Bug #670171 - Add LVM PV read-write support
Add creation of Physical Volumes specifying LVM2 metatdata format:
lvm pvcreate -M 2 /dev/DEVICE
Also set the partition type to identify its contents as LVM. Note that
libparted treats every partition type as a file system except LVM which
it treats as a flag, hence GParted displaying "lvm" in the Manage Flags
dialog. Never the less libparted set the partition types correctly.
For MBR partitioning the type is 8e "Linux LVM" and for GPT partitioning
the type is E6D6D379-F507-44C2-A23C-238F2A3DF928. Setting the partition
type as LVM is not strictly required as LVM2 scans the contents of all
partitions looking for PVs, but it is best practice.
Bug #670171 - Add LVM PV read-write support
Most file systems report intrinsic unallocated space using the statvfs()
system call when mounted, but not using their own tools. They are:
ext2/3/4, fat16/32, hfs, nilfs2, reiserfs and xfs. Showing either a
little or no unallocated space, depending on whether a file system is
mounted or not, could be confusing to the user.
When all file systems are created filling their partitions the unused
figure reported by statvfs() and their own tools are the same or very
close. Also the used plus unallocated figure from statvfs() agrees with
the used figure from their own tools.
For all file systems don't display intrinsic unallocated space (that
below the threshold of 2 to 5%), instead include it as used space. As
soon as the amount of unallocated space becomes significant display it
everywhere and also trigger the warning.
For display purposes always use the new Partition methods:
get_sectors_used(), get_sectors_unused(), and get_sectors_unallocated().
When calculating new usage figures during Paste and Resize/Move
operations directly access sectors_used, sectors_unused and
sectors_unallocated members.
Bug #499202 - gparted does not see the difference if partition size
differs from filesystem size
When pasting a copied partition into an existing partition set its space
utilisation so that any unallocated space is displayed correctly before
the operation is applied. If the destination partition is larger the
file system will be grown to fill the partition.
NOTE:
GParted will attempt to grow the the file system in this situation
regardless of whether the file system supports it or not. These file
systems: exfat, hfs, hfs+, reiser4 and ufs can't be grown and will fail
with "growing is not available for this file system". The preview will
also be wrong in this case for the same reason. Everything will be
depicted correctly after the refresh.
When formatting an existing partition default its space utilisation to
unknown for display before the operation is applied.

AFAICS, there is no reason to manually copy all partition fields,
or to manually initialize the copy of the new partition object.
So now the partition object is simply copied using assignment.
AFAICS, there is no reason to manually copy all partition fields,

GParted_Core::set_device_partitions() creates and initialises the
partition objects based on the partitions on the disk using
partition.Reset() and partition.Set(). These methods never set the
alignment attribute.
Copy and pasting into an existing partition calls GParted_Core::
snap_to_alignment() to adjust the start and end of the newly created
in memory partition object. When pasting into unallocated space the
user has selected the required alignment and this is exactly what is
needed. However when pasting into an existing partition the in memory
partition object should always match the actual partition boundaries on
disk. Unfortunately the partition boundaries are adjusted based on
reading the uninitialised alignment attribute.
Initialise the alignment attribute of newly created partition objects to
ALIGN_STRICT. Also, when pasting into an existing partition set the
alignment of that partition object to ALIGN_STRICT so that no boundary
adjustment is performed.

GParted's representation of it
A Volume Group is active when any of its Logical Volume mappings are
loaded (and enabled) in the Kernel's device-mapper driver. Therefore
all the Physical Volumes in the VG (must be considered) active too.
This is exactly equivalent to a mounted file system, as the kernel is
actively using the partition. Mark active LVM2 PVs as busy in GParted.
Don't use statvfs() for determining sector usage of busy LVM2 PVs as it
will fail with "statvfs(VGNAME): No such file or directory". Instead
always use the LVM2 PV specific method.
Display the status of the LVM2 PV in the Information dialog using one of
the following relevant messages:
Not active (Not part of any volume group)
VGNAME not active
VGNAME active
(The code uses the VGNAME stored in the partition's first mount point,
as displayed in the "Mount Point" column, rather than going back to the
primary source of the information in the LVM2_PV_Info class).
Temporarily prevent GParted from offering to unmount LVM2 PVs until
activating and deactivating Volume Groups is implemented later.
Bug #160787 - lvm support
As the Mount Point column is being borrowed to display the PV's VGNAME,
also suppress generation of the "Mount on" submenu for LVM2 PVs.
