While this release adds some features, they are new interfaces or changes enabled only via a new option, or via the presence of a new on-disk bit. As such, they should be "safe" enough that I can still call this a stable release.
Special thanks to Hans De Goede for numerous fixes and additions. For a summary of changes and contributors, see: http://git.debian.org/?p=parted/parted.git;a=shortlog;h=v2.0 or run this command from a git-cloned parted directory: git shortlog v2.0..v2.1 To summarize the gnulib-related changes, run these commands from a git-cloned parted directory: git checkout v2.0 git submodule summary v2.1 Here are the compressed sources: ftp://ftp.gnu.org/gnu/parted/parted-2.1.tar.gz (2.8MB) ftp://ftp.gnu.org/gnu/parted/parted-2.1.tar.xz (1.4MB) Here are the GPG detached signatures[*]: ftp://ftp.gnu.org/gnu/parted/parted-2.1.tar.gz.sig ftp://ftp.gnu.org/gnu/parted/parted-2.1.tar.xz.sig To reduce load on the main server, use a mirror listed at: http://www.gnu.org/order/ftp.html [*] You can use either of the above signature files to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify parted-2.1.tar.gz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys B9AB9A16 and rerun the `gpg --verify' command. This release was bootstrapped with the following tools: Autoconf 2.65.8-b4f0a Automake 1.11a Gnulib v0.0-3019-g213efc0 Gperf 3.0.3 NEWS * Noteworthy changes in release 2.1 (2009-12-20) [stable] ** New features new --align=<align> commandline option which 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 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 mininal value uses the minimum aligment needed to align the partition properly to physical blocks, which avoids performance degradation. Where as the optimal value uses a multiple of the physical block size in a way that guarantees optimal performance. The min and opt values will only work when compiled with libblkid >= 2.17 and running on a kernel >= 2.6.31, otherwise they will behave as the none --align value. libparted: new functions to set per disk (instead of per partition) flags: ped_disk_set_flag() ped_disk_get_flag() ped_disk_is_flag_available() ped_disk_flag_get_name() ped_disk_flag_get_by_name() ped_disk_flag_next() libparted: new per disk flag: PED_DISK_CYLINDER_ALIGNMENT. 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. libparted: new functions to return per-partition-table-type limits: - ped_disk_max_partition_start_sector: Return the largest representable start sector number for a given "disk". - ped_disk_max_partition_length: Return the maximum partition length for a given "disk". new command "align-check TYPE N" to determine whether the starting sector of partition N is TYPE(minimal|optimal)-aligned for the disk. E.g., parted -s /dev/sda align-check min 1 && echo partition 1 is min-aligned parted -s /dev/sda align-check opt 2 && echo partition 2 is opt-aligned The same libblkid and kernel version requirements apply as for --align Add functions to libparted to get minimal and optimal alignment information from devices: ped_device_get_minimal_aligned_constraint() ped_device_get_optimal_aligned_constraint() ped_device_get_minimum_alignment() ped_device_get_optimum_alignment() The same libblkid and kernel version requirements apply as for --align Add ped_disk_get_partition_alignment() function to libparted to get information about alignment enforced by the disk type. ** Bug fixes parted can once again create partition tables on loop devices. Before, "parted -s /dev/loop0 mklabel gpt" would fail. [bug introduced in parted-1.9.0] improved >512-byte sector support: for example, printing a table on a 4k-sector disk would show "Sector size (logical/physical): 4096B/512B", when the sizes should have been "4096B/4096B". gpt tables are more rigorously checked; before, partition entry array CRCs were not checked, and we would mistakenly use the AlternateLBA member of a known-corrupt primary table. improved dasd disk support, in previous versions calling ped_disk_new_fresh() or ped_disk_duplicate() on a dasd type PedDisk would fail. This is fixed now. handle device nodes created by lvm build with udev synchronisation enabled properly. when printing tables, parted no longer truncates flag names
