[Libguestfs] ANNOUNCE: libguestfs 1.42 - tools for accessing and modifying virtual machine disk images
I'm pleased to announce the release of libguestfs 1.42, a library and
set of tools for accessing and modifying virtual machine disk images.
You can find out more about the project here:
http://libguestfs.org/
Release notes (http://libguestfs.org/guestfs-release-notes-1.42.1.html)
Please note that virt-v2v, virt-p2v and the boot analysis tools were
moved out of the libguestfs package / repository into separate
projects. See:
· https://github.com/libguestfs/virt-v2v
· https://github.com/libguestfs/virt-p2v
· https://github.com/libguestfs/libguestfs-analysis-tools
Those projects are now on a separate release cycle. Release notes are
published separately.
New features
Add support for the Vala language (Corentin Noël).
Add support for the Rust language (Hiroyuki Katsura, sponsored by
Google Summer of Code).
Reproducible builds (Chris Lamb).
Advanced Format disks (which use 4K sectors) can now be processed by
libguestfs. Use the new optional "blocksize" parameter to
"guestfs_add_drive_opts", and the --blocksize option added to
several
tools (Nikolay Ivanets).
Windows CompactOS (NTFS file compression) is now supported.
New features in existing tools
Advanced machine readable output in various virt tools now supports
JSON output, and writing logs to a numbered file descriptor (Pino
Toscano).
virt-filesystems tool now more accurately reports filesystem total
size, in the case where for example the filesystem does not occupy the
whole of its containing device (Pino Toscano).
Language bindings
Python ≥ 2.7 is required.
Python bindings are now more extensively tested (Hiroyuki Katsura).
Python bindings should now work with Python ≥ 3.8.
Multiple fixes to avoid crashes in the Python bindings (Sam Eiderman).
OCaml bindings are compiled with "-DCAML_NAME_SPACE" to ensure
no
non-caml_-namespaced symbols are used (Pino Toscano).
OCaml bindings should now work with OCaml 4.09 and 4.10.
Erlang has deprecated the old "erl_interface" library which we
use for
Erlang bindings. It will be removed in OTP 22, which will permanently
break Erlang support unless someone steps forward to update the Erlang
bindings in libguestfs.
Fix compatibility with newer cgo for Go bindings (Tomáš Golembiovský).
Go API error handling is now more idiomatic (Csaba Henk).
Update documentation about how to handle boolean parameters in Ruby
bindings (Csaba Henk).
Inspection
Libguestfs can now extract icons for Gentoo, newer SUSE and
OpenMandriva guests. Improved extraction of RHEL icons. (Pino
Toscano).
Inspection returns the osinfo IDs of newer Windows versions, and
rolling Linux distros (Pino Toscano).
OpenMandriva is now detected (Bernhard Rosenkränzer).
Arch Linux detection improvements (Pino Toscano).
Architectures and platforms
Libguestfs can now be compiled on OpenMandriva (Bernhard Rosenkränzer).
Ubuntu fix for enabling network support (Ioanna Alifieraki).
Other
Use of deprecated libguestfs APIs will now cause compiler deprecation
warnings by default, whereas previously you have to enable these
warnings. To turn off these warnings use
"-DGUESTFS_NO_WARN_DEPRECATED=1". A new feature is that you
can now
disable deprecated APIs completely if you want, using
"-DGUESTFS_NO_DEPRECATED=1" (Pino Toscano).
Fix hostname in virt-builder templates (Pino Toscano).
The single large release notes file is now split into multiple
documents organized by version.
The "--key" option of several tools was broken, especially if
you tried
to use the option to pass multiple keys. This has been fixed and a
regression test added.
Augeas exceptions occurring in daemon (eg. during inspection) will now
produced detailed errors (Pino Toscano).
Security
No security issues were found in this release.
API
New APIs
"luks_uuid" returns the UUID of a LUKS device (Pino Toscano).
Other API changes
Cope with new output from the "btrfs scrub" command. There is
no
visible change at the API level.
New optional parameter "blocksize" added to
"guestfs_add_drive_opts" to
support Advanced Format disks (Nikolay Ivanets).
Build changes
Minimum version of Augeas required is 1.2.0 (Pino Toscano).
"common/" subdirectory is now a git submodule shared with the
virt-v2v
project.
Supermin ≥ 5.1.18 is required.
There were several bugs in libvirt 5.10.0 and 6.0 which affected
libguestfs. It is highly advisable to use libvirt 6.1 where these bugs
are fixed (versions of libvirt < 5.10.0 are also fine).
Many gnulib modules which we were not using or which we used in only a
few places have been removed (Pino Toscano).
Multiple fixes for builddir != sourcedir builds (Pino Toscano).
A new "bundled/" subdirectory contains one bundled library that
we
currently use, "ocaml-augeas" (Pino Toscano).
Fix compatibility issues when being compiled with GCC 10.
Internals
When linking OCaml programs, automake silent rules and the
"V=1" flag
are both now obeyed (Pino Toscano).
The "guestfs_device_index" API was reimplemented in library
code
instead of in the daemon. There should be no observable effect of this
change.
Since Linux 5.6 enumerates "/dev/sdX" devices in parallel,
libguestfs
was changed to map API device names to appliance device names, and then
do the reverse mapping when returning names from the appliance.
Hopefully this should have no observable effect, but can produce
somewhat confusing debugging messages since device names in the debug
might not match device names passed in to APIs. Furthermore the
"root=UUID=..." option is always passed to the appliance
(instead of
naming the device containing the root filesystem).
We expect to move from the Zanata service to the Weblate service for
translated strings. For more information see

Hi, will a stable-1.42 branch be created from the v1.42.0 tag? (not advocating either choice, just asking) Thanks, -- Pino Toscano
