	dos: set HFS/HFS+ partition identifier to proper value
	The correct value for an "hfs" partition identifier is 0xAF.
	Previously the partition identifier was incorrectly set to 0x83.
	* libparted/labels/dos.c (PARTITION_HFS): Define.

	sun: initialize basic partition table fields
	libparted completely ignores basic fields (version, nparts and sanity)
	in the sun VTOC, then for example fdisk prints warnings for such
	partition table:

		# fdisk -lu /dev/sdb
		Detected sun disklabel with wrong version [0x00000000].
		Detected sun disklabel with wrong sanity [0x00000000].
		Detected sun disklabel with wrong num_partitions [0].

	It seems that the current libparted sun support follows old Linux
	kernel code, but the code was changed 3 years ago (see kernel commit
	3961bae0ac030a70ae2e0578270203889021f1a1).

	Note that the number of partitions (nparts) is optional for Linux
	kernel, but fdisk(8) strictly requires SUN_DISK_MAXPARTITIONS (=8)
	there. This patch sets nparts to SUN_DISK_MAXPARTITIONS rather then
	use a real number of partitions.

	* NEWS (Bug fixes): Mention it.
	* libparted/labels/sun.c: Update from kernel.
	* tests/t4001-sun-vtoc.sh: New file.  Test for this.

	needs_clobber value in ped_disk_duplicate()".
	* tests/Makefile.am (TESTS, check_PROGRAMS): Add dup-clobber.

2010-02-22  Hans de Goede  <hdegoede@redhat.com>

	libparted: copy the needs_clobber value in ped_disk_duplicate()
	Most duplicate disk_ops use ped_disk_new_fresh, which sets needs_clobber
	to 1. This would lead to clobbering the disk when committing a duplicate
	disk even when the original disk was not made with ped_disk_new_fresh.
	* libparted/disk.c (ped_disk_duplicate): Copy the needs_clobber member.
	* NEWS (Bug fixes): Describe it.

2010-02-22  Curtis Gedak  <gedakc@gmail.com>

	linux: add wait time and retries to kernel partition reread
	Occasionally when using parted with newer GNU/Linux kernels (2.6.31)
	and udev (145), the kernel would fail to reread the partition table.
	This could lead to problems with subsequent actions such as formatting
	the partition.

	Basically this patch increases the retry_count, and adds one sleep(1)
	function call prior to the the last few ioctl() calls.

	This patch might not be a perfect solution to this problem of "failure
	to inform kernel of partition changes", but it does significantly
	reduce the likelihood of encountering the problem.

	Details on the testing results and procedures used can be found at
	the following link:
	https://bugzilla.gnome.org/show_bug.cgi?id=604298#c9

	* libparted/arch/linux.c (_kernel_reread_part_table): Sleep for a
	full second if retry_count makes it down to "3".  Start it at 9
	rather than at 5.
	* NEWS (Bug fixes):

	parted: change warnings when initial constrained mkpart fails
	In do_mkpart we first try to create a partition using a constraint
	derived from the user input intersected with the devices alignment
	needs. And if that fails we try again without any constraint.

	However the warning given when this happens only takes into account
	the user not getting what he asked for, while the alignment might be
	a problem too (or even the only problem). So this patch adds a check
	to see if the user really did not get what he asked before giving that
	warning, and adds a new check + warning to see if the created partition
	is properly aligned.
	*parted/parted.c (do_mkpart,do_mkpartfs): change warnings when initial
	constrained mkpart fails.

	parted: honor --align option also in mkpartfs, resize and print cmds
	* parted/parted.c (do_mkpartfs,do_print,do_resize): Honor --align.

	linux: handle incomplete topology information
	The topology information returned by libblkid is not always complete
	(as the kernel does not always have complete information).
	This patch makes the linux_get_*_alignment() alignment functions handle
	this. The algorithm used for linux_get_optimum_alignment is:
	1) Always use the reported aligment offset as offset
	2a)If optimal io size is present in the topology info use that as grain
	2b)If optimal io size is not present in topology info and aligment
	   offset is 0 and minimum io size is a power of 2, use the device.c
	   default optimal alignment (grain 1MiB).
	2c) If neither 2a and 2b, use the minimum io size, or if that is not
	   defined, use the physical sector size as grain (iow the minimum
	   alignment).
	The algorithm used for linux_get_minimum_alignment is:
	1) Always use the reported aligment offset as offset
	2) Use the minimum io size, or if that is not defined the physical
	   sector size as grain.
	* libparted/arch/linux.c (linux_get_*_alignment): Handle incomplete
	topology information.

	libparted: Give device_get_*_alignment sane defaults
	When the topology info is incomplete or non existent, return something
	more sensible than NULL (which ends up being interpreted as
	PedAlignmentAny in most cases). The default minimum alignment aligns to
	physical sector size, the default optimal alignment is 1 MiB, which is
	what vista and windows 7 do.
	* libparted/device.c (device_get_*_alignment): Add default aligments.
	* NEWS (New features): Mention it.

	linux: correct phys_sector_size setting
	1) Use the logical sector size as physical sector size instead of 512
	   when not compiled with libblkid support, this fixes problems
	   with logical sector size > physical sector size.
	2) blkid_topology_get_physical_sector_size() returns 0 when it fails
	   to determine the physical sector size, handle this.
	* libparted/arch/linux.c (_device_set_sector_size): Correct
	phys_sector_size setting.
	* NEWS (Bug fixes): Mention it.

	The partition_print_flags() function was truncating the flag names,

	is not good and was causing issues when printing tables in Russian:
	http://bugzilla.redhat.com/show_bug.cgi?id=543029

	Since the truncating does not seem to make sense at all this patch
	simply removes it (it was likely an attempt to stay within 80 chars
	when printing, but as one partition can have multiple flags set this
	won't work)

	* parted/parted.c (partition_print_flags): Don't truncate flag names.

	ui: add --align command-line option to specify mkpart alignment
	The new --align command-line option can have the following values:
	none:     Use the minimum alignment allowed by the disk type
	cylinder: Align partitions to cylinders (the default)
	minimal: Use minimum alignment as given by the disk topology information
	optimal: Use optimum alignment as given by the disk topology information

	Note the "minimal" and "optimal" values will use layout information
	provided by the disk to align the logical partition table addresses
	to actual physical blocks on the disks.  The "minimal" value is the
	minimum aligment needed to align the partition properly to physical
	blocks, which avoids performance degradation.  Whereas the "optimum"
	alignment align's to a multiple of the physical block size in a way
	that guarantees optimal performance.

	The "minimal" and "optimal" values are useful only when parted is
	compiled with libblkid >= 2.17 and running on a kernel >= 2.6.31,
	otherwise they are equivalent to --align=none.

	* parted/parted.c (ALIGNMENT_ enum values): New enum.
	(options, options_help): Add --align option.
	(align_args, align_types, alignment): New global variables.

	libparted: add disk flag functions and PED_DISK_CYLINDER_ALIGNMENT flag
	Sometimes we want to be able to set flags at the disk level rather then
	at the parition level, to influence how new partitions will be created
	for example.  This patch adds functions to do this (modelled after the
	partition flag functions), and adds a PED_DISK_CYLINDER_ALIGNMENT flag.

	This flag (which defaults to true) controls if disk types for which
	cylinder alignment is optional do cylinder alignment when a new
	partition gets added. This flag is available for msdos and sun
	disklabels (for sun labels it only controls the aligning of the end of
	the partition).

	libparted: ped_disk_clobber_exclude: remove now-unused function
	I see no utility in ped_disk_clobber_exclude (just a thin wrapper
	around ped_disk_clobber), so am removing the interface.
	* include/parted/disk.h (ped_disk_clobber_exclude): Remove prototype.
	* libparted/disk.c (ped_disk_clobber_exclude): Remove function.
	Now that all callers use NULL as 2nd argument, replace each call

	ped_disk_clobber: change semantics
	Why?  Because if we're going to clobber a partition table,
	it is wasteful and error prone to try to interpret as a partition
	table whatever existing data there may be.  It may be corrupt, or
	a mix of two or more types.  It is far cleaner just to zero out
	the key sectors.

	The previous mechanism was like this:
	for each partition table type, T,
	    # See if the device has a partition of type T.
	    # If so, run the partition-table-specific code to clear it.
	    if t->ops->probe (dev)
	      t->ops->clobber (dev)
	Instead, simply zero out the first few and last few sectors.
	Except for GPT, for which we exempt the first sector (the pMBR).
	In order to zero out even the bits DASD uses for its identifying
	strings, we have to clobber at least the 8.5KiB at the beginning
	of the disk, so round up to 9KiB.
	* libparted/disk.c: Include "labels/pt-tools.h".

	dasd: allow the use of a *regular* backing file
	Before this change, dasd partition tables had to be associated with
	very specialized block devices available only on IBM s390 systems.
	This made testing especially hard.  Not only did you need access
	to one of those relatively uncommon systems, but you also needed
	access to a spare block device.  In addition, many of Parted's
	tests may be run as a non-privileged user, using regular files,
	and those tests would fail when run on an s390.

	This change makes it so you may now write a DASD partition table
	to a regular backing file, just as you may with any other supported
	partition table type.  However, note that even now, DASD support
	is conditionally compiled and hence enabled only when compiling
	for an s390 target.

	* libparted/arch/linux.c (_device_set_sector_size) [__s390__]:
	Allow operation on a device of type PED_DEVICE_FILE, as well as
	those of type PED_DEVICE_DASD.
	* libparted/labels/fdasd.c: Include <parted/device.h>.
	(fdasd_get_geometry): Add a new "dev" parameter, required for
	dev-phys-sector_size, which is needed in order to initialize
	the "anc" structure without using the device-specific ioctls.
	When file descriptor "f" refers to a regular file, initialize
	"anc", "dasd_info", etc. from other sources (fstat and dev->).
	Update all callers to reflect added parameter.
	(fdasd_check_api_version): Skip ioctl-calling tests when "f" is
	a regular file.
	* include/parted/fdasd.h: Update fdasd_get_geometry prototype.
	* libparted/labels/dasd.c (dasd_probe): Also allow PED_DEVICE_FILE.
	(dasd_alloc_metadata): Initialize arch_specific->real_sector_size,
	which is used in calculating vtoc_end.

	There is no point in clearing what the primary header says is the
	AlternateLBA, since once the primary header and the last sector
	are cleared, there is no risk of any tool using it by mistake.

	tests: t0000-basic.sh: minor correction
