Found that older but still supported distributions Debian 8 and
Ubuntu 14.04 LTS don't have directory /dev/disk/by-path/. This is used
by the BlockSpecial unit test as a source of a symbolic link to a block
special device.
This causes the unit test to fail like this:
$ cd tests
$ ./test_BlockSpecial
...
[ RUN ] BlockSpecialTest.NamedBlockSpecialObjectBySymlinkMatches
test_BlockSpecial.cc:137: Failure
Failed
get_link_name(): Failed to open directory '/dev/disk/by-path'
test_BlockSpecial.cc:168: Failure

[ FAILED ] BlockSpecialTest.NamedBlockSpecialObjectBySymlinkMatches (0 ms)
...
[ FAILED ] 1 test, listed below:
[ FAILED ] BlockSpecialTest.NamedBlockSpecialObjectBySymlinkMatches

Which in turn causes make check and make distcheck to fail.
Use directory /dev/disk/by-id/ instead as it always exists.
Increase the minimum required version of gtkmm to 2.16.0, thus allowing
removal of HAVE_GTK_SHOW_URI autoconf definition and associated fallback
code.
Bug 794253 - Desupport RHEL / CentOS 5 and raise minimum required
versions to glibmm 2.14.0 and gtkmm 2.16.0
Increase the minimum required version of gtkmm to 2.11.1, thus allowing
removal of:
* HAVE_SET_DEFAULT_ICON_NAME autoconf definition and associated
optional code.
* INSTALL_PIXMAPS_DIR automake conditional and associated make
instructions.
This is reversing these 3 commits, except for the higher minimum gtkmm

E2fsprogs 1.41.0 (from 10 July 2008) first included ext4 support [1].
As RHEL / CentOS 6 is now the oldest supported distribution, and that
includes e2fsprogs 1.41.12 (from 22 August 2009) [2] all the e2fs
programs support ext4 so it is no longer necessary to also depend on
finding mkfs.ext4 before enabling each supported capability for ext4.
This makes the ext2::get_filesystem_support() look like all the others
in which each supported capability only depends on the presence of the
relevant file system specific command.

Bug 794253 - Desupport RHEL / CentOS 5 and raise minimum required
versions to glibmm 2.14.0 and gtkmm 2.16.0
PATCHSET OVERVIEW:
As of 31 March 2017 RHEL / CentOS 5 reached the end of their support
[1][2]. Therefore remove code which supports them. This makes RHEL /
CentOS 6 the oldest supported distribution. So the minimum required
versions of glibmm and gtkmm can be increased dropping some autoconf
checks and conditional code supporting older versions of these
libraries. This will undo the bulk of these these previous bug fixes:
* GParted 0.21.0
Bug 738706 - Add support for ext4 on RHEL/CentOS 5.x
* GParted 0.16.1
Bug 695279 - Fix GParted doesn't compile on RHEL / CentOS 5.9

THIS PATCH:
Remove checks for e4fsprogs commands, removing support for ext4 on
RHEL / CentOS 5.x. This is reverting earlier commit:

Check for e4fsprogs commands for ext4 support on RHEL/CentOS 5.x (#738706)
Mkfs_cmd member variable is being kept as a convenience so that it is
created once rather than on each use. Also note that as it is a
Glib::ustring type object, it's constructor will be called which will
initialise it to the empty string so it doesn't need initialising to the
empty string in the initialiser list of the ext2() constructor itself.

Use of USE_GNOME2_MACROS is deprecated in GNOME 3 and produced this
warning:
$ ./autogen.sh
/usr/bin/gnome-autogen.sh
...
***Warning*** USE_GNOME2_MACROS is deprecated, you may remove it from autogen.sh
...
It's use appears to have been removed first from GNOME 2.8 with this
commit from 2004:

delete some files that were unused after the reorganisation
The oldest supported distribution is RHEL / CentOS 6 which is using
gnome-common-2.28.0 from 2009. Therefore unconditionally remove the
USE_GNOME2_MACROS setting.
Also confirmed that it makes no difference by running ./autogen.sh with
and without USE_GNOME2_MACROS being set. The produced GParted build
trees were the same. Therefore the release and executable can't be
affected.
Scrollkeeper and the associated OMF catalog files are used by the
GNOME 2 version of yelp to display the GParted help manual. To see how
this works try the following command:
yelp ghelp:gparted
GNOME version 3 and higher yelp do not require scrollkeeper or the OMF
catalog files to properly display the GParted help manual. And in fact
GNOME 3 deprecated the GNOME 2 method of building and installing GNOME
help documents altogether; including use of GNOME_DOC_INIT autoconf
macro, the gnome-doc-utils package and use of scrollkeeper.

Further, the next release of Debian, Debian 10 (Buster), will be
removing the scrollkeeper / rarian package.

This is needed to build GParted documentation on still supported GNOME 2
distributions RHEL / CentOS 6. So avoid requiring deprecated
scrollkeeper on GNOME 3 by automatically disabling scrollkeeper database
updates when the scrollkeeper-update command is not available.
Executable | Configure option used | Use scrollkeeper

exists? | | for GParted?
--------------------+------------------------+-------------------
Yes | <none> | Yes
Yes | --enable-scrollkeeper | Yes
Yes | --disable-scrollkeeper | No
| |
No | <any> | No
Note that because GParted is still using the GNOME 2 documentation build
system it still builds and installs OMF files. It is just that they are
not required with GNOME 3 yelp and this commit automatically disables
updating the scrollkeeper database when the scrollkeeper-update command
is not available.

Struct FS and struct FS_Limits are strongly related to the FileSystem
class, both being return values from members and associated with storing
file system attributes. Move their definitions from Utils.h into
FileSystem.h.
There are too many different types of things named "filesystem" in the
GParted code with the potential to cause confusion. Namely:
std::vector<FS> FILESYSTEMS
Vector of file system capabilities.
class FileSystem Base class interfacing to file system
specific executables for querying and
modification.
enum FILESYSTEM Symbolic constants representing each file
system type.
Many recent written or re-written functions already used a variable
named fstype. Rename enum FILESYSTEM to enum FSType to clearly
distinguish it from the other things with very similar names. Only
changing the name of the enumeration, not the name of variables of that
type too because that is a lot more lines of code and those can be
changed when the relevant code is re-written.
Try to format an existing partition with a file system which doesn't
fit. The error dialog reporting the partition as too small or too large
always claimed the file system was encrypted, whether it was or not.
For example trying to format a 128 MiB partition as btrfs produces this
error dialog:
(-) Cannot format this file system to [Encrypted] btrfs
A [Encrypted] btrfs file system requires
a partition of at least 256.00 MiB.
[ OK ]
This commit:
88136c96d7
Extend functions generating encrypted file system string (#774818)
just completely missed handling the case for non-encrypted file systems
in Utils::get_filesystem_string(). Add the missed code.
There are multiple repetitions of the same code getting a FileSystem
object, checking for NULL and then calling the file system specific
get_filesystem_limits(). Extract that into a common function.
GParted_Core::get_filesystem_limits() can't use the file system from the
passed Partition object because that is the current file system which
will be different from the intended file system for new and format
operations. So would look up the wrong derived FileSystem specific
object and call the wrong get_filesystem_limits(). Hence still needing
fstype as a separate parameter to pass the intended file system.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
UDF file system minimum and maximum size limits are defined in terms of
numbers of file system blocks. So when resizing an existing file system
compute the byte size limits from the existing UDF file system's block
size. Alternatively when creating a new UDF file system use the
device's sector size as the multiplier instead.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
As described in the previous commit, this is so that file system
specific implementations can dynamically determine size limits based on
Partition object attributes: such as the device sector size and the file
system block size. (Assuming set_used_sectors() sets
partition.fs_block_size for the type of file system in question).
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Background information about UDF is that when creating a file system
it's block size must match the underlying device's sector size. For
optical media like CDs and DVDs that is 2K. For hard drives that is
usually 512 bytes or 4K. However if a UDF file system has been copied
from a device with a different sector size the UDF block size won't
match the sector size. Linux will happily mount such UDF file system.
Therefore the derived udf::get_filesystem_limits() will need access to
the file system block size when determining the size limits of an
existing UDF file system being resized and use the device sector size
when a new UDF file system is being created. All this can be queried
from an appropriate Partition object passed to get_filesystem_limits().
All the calls to get_filesystem_limits() have an appropriate Partition
object available already, except in Win_GParted::activate_reformat()
when composing a format operation. Or more correctly
activate_reformat() constructs temp_ptn, a suitable Partition object,
including with fs_block_size member defaulting to -1 indicating not a
resize, but not until after the file system size limits had been checked
and get_filesystem_limits() called.
Therefore reorder the code in activate_paste() so that the file system
size limits are checked after the wanted Partition object has been
created. No functional change with this commit.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
All the code has been switched to call get_filesystem_limits() and use
struct FS_Limits. Remove struct FS members .MIN & .MAX.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Change Dialog_Partition_New to use a fs_limits rather than struct FS
and .MIN and .MAX. No passing of struct FS_Limits required. Just use
the FILESYSTEMS vector of struct FS to provide the file system type and
look up it's size limits each time the selection changes.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Refactor Win_GParted::activate_resize() to query the file system size
limits using the new get_filesystem_limits() method and pass those
limits into the dialog class as struct FS_Limits.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Changes the internal code in Dialog_Partition_Resize_Move to use
fs_limits instead of fs.MIN and fs.MAX. The limits are still passed
into the constructor via struct FS and it's members .MIN and .MAX but
immediately used to assign to fs_limits.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Refactor Win_GParted::activate_paste() to query the file system size
limits using the new get_filesystem_limits() method and pass those
limits into the the dialog class as struct FS_Limits.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Adds working copy fs_limits member into common Dialog_Base_Partition
class. Changes the internal code in Dialog_Partition_Copy class to use
fs_limits instead of fs.MIN and fs.MAX. The limits are still passed
into the constructor via object of struct FS and it's members .MIN and
.MAX but immediately used to assign to the fs_limits member.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Duplicate the assignment of file system size limits into
struct FS_Limits, matching the fixed values currently assigned to
struct FS members .MIN and .MAX.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
PATCH SET OVERVIEW:
Currently the supported actions of each file system and their size
limits are stored in struct FS objects. These are created by calling
file system specific derived implementations of
FileSystem::get_filesystem_support(). This happens when GParted is
started or when a when a rescan for supported actions is performed. The
file system size limits are expressed as a fixed number of bytes.
The maximum UDF file system size is specified in terms of file system
block size units. Also the file system block size must match the sector
size of the underlying device. Typically 2K for optical media and 512
bytes or 4K for hard drives.
Therefore GParted can't properly express the true UDF file system size
limits because they depend on the block size of an existing UDF file
system or the sector size of the device for new UDF file systems. In
fact other file systems such as EXT2/3/4 and XFS actually express their
maximum file system size in terms of numbers of file system blocks but
these tend to always be 4K and don't have to match the sector size of
the underlying device, so fixed byte values tend to suffice.
To update GParted for this, first separate file system size limits from
struct FS into struct FS_Limits and provide new
FileSystem::get_filesystem_limits() method to allow the limits to be
queried independently of the calls to get_filesystem_support().
Second, pass Partition objects and allow derived get_filesystem_limits()
implementations.
THIS PATCH:
Just creates a separate structure storing fixed value file system
minimum and maximum size limits along with getter method
get_filesystem_limits().
