Release Notes for Libguestfs 1.4
These release notes only cover the differences from the previous stable/dev branch split (1.2.0). For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball.
New features
- guestfish lets you choose a prepared disk image, eg: guestfish -N fs:ext4 - Add write support to guestmount (FUSE) module. - virt-resize can now resize the content of partitions and logical volumes in the guest, and we have better support for shrinking guests. - Bash tab-completion script for guestfish. - Add ZFS support to virt-rescue. - New tool 'virt-make-fs' for creating filesystems with content. - Allow suffixes on any guestfish number parameter, eg. "1M". - guestfish 'man' command opens the manual page. - guestfish supports a "heredoc" syntax for uploading files: upload -<<_end_ /foo content _end_ - Some guestfish commands now print their output in octal or hex where appropriate (RHBZ#583242). - Allow dash prefix on guestfish command line. This ignores any error from the second command: (RHBZ#578407) guestfish -- cmd1 : -cmd2 : cmd3 - guestfish -h / help command now returns an error for non-existent commands (RHBZ#597145). - New 'supported' command in guestfish to list optional groups of commands which are supported by the daemon / configuration. - virt-inspector and guestfish -i now work for filenames which contain spaces (RHBZ#507810). - Change the protocol to use link-local addresses, to avoid conflicting with any address that the host might be using (RHBZ#588763). - libguestfs now sets the correct time and timezone on filesystem modifications. - Sort the domains into alphabetical order in virt-df. - Make mkfs-b command work for FAT and NTFS by mapping the blocksize parameter to the cluster size (RHBZ#599464). - Add version numbers to Perl modules (RHBZ#521674). - Localization now works for all the libguestfs tools (RHBZ#559963). - Tools now support filesystem-on-image VMs (RHBZ#590167). - virt-list-partitions has a '-t' option to show the total size of disks. - Include extra Augeas lenses in the supermin appliance (Matthew Booth). - Add error and close callbacks. - Add explicit close method in the Perl API. - Multiple fixes for RHEL 5 compatibility. - Multiple fixes for Debian/Ubuntu compatibility. - Multiple revisions to improve the documentation.
Security
- Fix a potential DoS in virt-inspector and virt-v2v if a specially crafted disk image contained a char device in place of one of the configuration files that we read under /etc (RHBZ#582484).
New APIs
- aug-clear - clear Augeas path - available-all-groups - return a list of all optional groups - base64-in - upload base64-encoded data to file - base64-out - download file and encode as base64 - checksum-device - compute checksums on the contents of a device - checksums-out - compute checksums of multiple files in a directory - debug-upload - upload a file to the appliance - fallocate64 - preallocate a file in the guest filesystem - fill-pattern - fill a file with a repeating pattern of bytes - get-umask - get the current umask - lvresize-free - expand an LV to fill free space - ntfsresize - resize an NTFS filesystem - ntfsresize-size - resize an NTFS filesystem (with size) - part-del - delete a partition - part-get-bootable - get the bootable flag of a partition - part-get-mbr-id - get the MBR type byte of a partition - part-set-mbr-id - set the MBR type byte of a partition - pvresize-size - resize a physical volume (with size) - pwrite - write to part of a file - resize2fs-size - resize an ext2/3/4 filesystem (with size) - txz-in - unpack compressed tarball to directory (RHBZ#580556) - txz-out - pack directory into compressed tarball (RHBZ#580556) - vfs-label - get the filesystem label - vfs-uuid - get the filesystem UUID - vgscan - rescan for LVM physical volumes, volume groups and logical volumes - write - create a new file - zero-device - write zeroes to an entire device
Internals
- Extend the generator to support testing optional features. - Stricter checks on input parameters to many calls (RHBZ#501893 RHBZ#501894) - Extend the protocol to support sending arbitrary 8 bit data buffers. - Ship 'BUGS' file with releases. This is a summary of the bugs in the Red Hat Bugzilla database. - Ship 'RELEASE-NOTES' file with releases, containing release notes. - Unify supermin appliance building into one place, in febootstrap 2.7. - Fix the protocol code to handle the case where both ends send cancel messages at the same time.
