=head1 RELEASE NOTES FOR LIBGUESTFS 1.52
|
|
|
|
These are the release notes for libguestfs stable release 1.52.
|
|
This describes the major changes since 1.50.
|
|
|
|
Libguestfs 1.52.0 was released on B<5 January 2024>.
|
|
|
|
=head2 Language bindings
|
|
|
|
The Python bindings now use C<bytes> (instead of C<str>) for the event
|
|
callback message, since it may contain arbitrary 8 bit data (thanks
|
|
Yonatan Shtarkman).
|
|
|
|
Also in the Python bindings, fix a rare crash, and avoid memory leaks
|
|
in event callbacks (thanks Yonatan Shtarkman, Laszlo Ersek, Eric
|
|
Blake).
|
|
|
|
Support for OCaml 5, and OCaml E<ge> 4.07 is now the minimum (thanks
|
|
Guillaume Munch-Maccagnoni, Jerry James, Josh Berdine, Jürgen Hötzel,
|
|
Vincent Laviron).
|
|
|
|
The OCaml bindings now release the runtime lock around calls to
|
|
C<guestfs_close>, since that call might be long-running (for example
|
|
it might have to shut down the appliance and synch disks).
|
|
|
|
=head2 Inspection
|
|
|
|
Support OpencloudOS (cunshunxia@tencent).
|
|
|
|
=head2 API
|
|
|
|
SELinux relabelling now runs in parallel, meaning it's a lot quicker
|
|
(Andrey Drobyshev).
|
|
|
|
Add support for lzma and zstd compression methods in tar APIs (like
|
|
C<guestfs_tar_in>) (Zixun LI).
|
|
|
|
C<guestfs_pvs_full> previously didn't always return the correct device
|
|
names. This has now been fixed.
|
|
|
|
C<guestfs_btrfs_filesystem_balance> fixed so it now works with more
|
|
modern btrfs tools (Jürgen Hötzel).
|
|
|
|
=head2 Tools
|
|
|
|
The L<guestfish(1)> I<--key> option now recognizes LVM names like
|
|
F</dev/mapper/rhel_bootp--73--75--123-root> (Laszlo Ersek).
|
|
|
|
guestfish I<--key> option also supports a new S<I<--key all:...>>
|
|
selector to try the same key on all devices.
|
|
|
|
In L<guestmount(1)> avoid calling C<fclose(NULL)> on error paths,
|
|
which might have caused a crash on some platforms.
|
|
|
|
=head2 Build changes
|
|
|
|
The C<RELEASES> file (which listed release dates) has been removed and
|
|
replaced with a simple C<RELEASE_DATE> macro in F<./configure>. This
|
|
should simplify builds.
|
|
|
|
Optionally L<passt(1)> may be used for networking (Laszlo Ersek).
|
|
|
|
L<dhcpcd(8)> is now used in preference to dh-client on Red Hat
|
|
platforms.
|
|
|
|
Old Ruby C<MiniTest> and C<Test::Unit> dependencies replaced with new
|
|
C<Minitest>.
|
|
|
|
Fix compatibility issues with libxml2 2.12.
|
|
|
|
=head2 Internals
|
|
|
|
On x86-64 we now use the more modern q35 machine type when running the
|
|
appliance. This should perform slightly better and has more
|
|
development attention from the qemu community. The change should be
|
|
invisible to libguestfs users.
|
|
|
|
Fix a segmentation fault when C<TERM> environment variable was set to
|
|
C<dumb> (Daisuke HATAYAMA).
|
|
|
|
Avoid a warning on modern Fedora which does not have F</selinux>
|
|
(Andrey Drobyshev).
|
|
|
|
Fix build on OpenSUSE LEAP 15 or other distros with a L<file(1)>
|
|
command which did not understand the I<-S> option (thanks Olaf
|
|
Hering).
