libvirt and systemd-resolved integration?
by Juan Orti Alcaine
Hello,
In the network bridges that libvirt creates there's a dnsmasq daemon to
resolve the VM's IPs. Is there any way to signal systemd-resolved from
libvirt to say that in the bridge interface there is a DNS server and a
domain?
Thank you.

Re-Launching the Java SIG
by Fabio Valentini
This past weekend I finally decided to jump off the cliff and attempt
to re-launch the Java SIG. It seems there's some interest in keeping
the Java stack maintained, it's just not focused or organized right
now.
What we did when starting the Stewardship SIG seems to have worked out
pretty well, so I'm trying to follow in those footsteps here:
- new proper FAS / pkgdb group: java-maint-sig ("java-sig" is occupied
by an old, unused bot account)
- new private mailing list: java-maint-sig (for RHBZ bugs - so,
possibly, also CVEs - hence, private)
- tracking project on pagure: https://pagure.io/java-maint-sig (for
maintenance scripts, tracking tickets, awesome package dashboards,
etc.)
There's already a public fedora mailing list for Java (java-devel),
and and IRC channel (#fedora-java on freenode.net), which we will
continue to use. Sadly, the existing wiki page for the Java SIG is
hopelessly outdated, so I'm tempted to just scrap it and point readers
to the pagure tracking project once it's set up beyond a basic README
file.
Major upcoming projects for the "new" Java Package Maintainers group include:
- managing OpenJDK 11 / Java 11 transition for hundreds of Java
packages in fedora 33
- starting to transition well-maintained Java packages from the
Stewardship SIG back into Java SIG
- possibly porting packages from gradle to maven to fix build issues
and broken dependencies
- transitioning from old java.net / JavaEE projects to the new ones
now under the eclipse-ee4j umbrella
I know that - among others - the PKI team, Neuro SIG, and Eclipse
maintainers depend on parts of the java stack for their packages, so I
hope that we can work together with them on these things, as well.
So, if you're interested, please consider joining this group effort.
I'll get new members set up with the FAS group / pagure project / mailing list.
Let's make this happen.

pdftk retired?
by Michael J Gruber
I just git a "broken dependencies" notice for a package that I maintain.
The reason is that "pdftk" got retired just the other day.
I may have missed a corresponding post on fedora-devel, but I think a
heads up notice to maintainers of depending packages may be in order
before you retire a package, as a general idea.
You see, unretiring a package is so much more work than changing
maintainership.
As for pdftk: I see 2 failed builds for version 1.45 and none for the
current version 2.02 (which probably breaks the api anyways). What are
the plans? Retire pdftk completely? Start fresh with pdftk2?
pdflabs, the maker of pdftk, provide binary as well as source rpms for
pdftk 2.02, by the way. I might even look into packaging it but don't
want to duplicate any existing efforts.

The future of legacy BIOS support in Fedora.
by Jóhann B. Guðmundsson
Given Hans proposal [1] introduced systemd/grub2/Gnome upstream changes
it beg the question if now would not be the time to stop supporting
booting in legacy bios mode and move to uefi only supported boot which
has been available on any common intel based x86 platform since atleast
2005.
Now in 2017 Intel's technical marketing engineer Brian Richardson
revealed in a presentation that the company will require UEFI Class 3
and above as in it would remove legacy BIOS support from its client and
datacenter platforms by 2020 and one might expect AMD to follow Intel in
this regard.
So Intel platforms produced this year presumably will be unable to run
32-bit operating systems, unable to use related software (at least
natively), and unable to use older hardware, such as RAID HBAs (and
therefore older hard drives that are connected to those HBAs), network
cards, and even graphics cards that lack UEFI-compatible vBIOS (launched
before 2012 – 2013) etc.
This post is just to gather feed back why Fedora should still continue
to support legacy BIOS boot as opposed to stop supporting it and
potentially drop grub2 and use sd-boot instead.
Share your thoughts and comments on how such move might affect you so
feedback can be collected for the future on why such a change might be
bad, how it might affect the distribution and scope of such change can
be determined for potential system wide proposal.
Regards
Jóhann B.

Upstream tip wanted: CI service for Big Endian acrhes
by Miro Hrončok
Recently I've reported some Big Endian related test failures to an
upstream project [0].
I was asked by an upstream project maintainer, whether I know some free
Continuous Integration services where they can easily run their
testsuite on Big Endian.
Any tips?
* Upstream uses Travis CI to test on x86_64 Linux (Ubuntu)
* Upstream uses AppVeyor to test on Microsoft Windows
* It's a pure Python project, noarch, but some changes need to be done
when loading/saving binary data (LE) with NumPy on BE system.
What I've considered:
* COPR (but there is no big endian arch)
* (Ab)using Koji (I guess that would be considered a bad practice?)
* using QUEMU on Travis CI [1]
Any better tips? Thanks

Fedora 34 Change: Route all Audio to PipeWire (System-Wide Change)
by Ben Cotton
https://fedoraproject.org/wiki/Changes/DefaultPipeWire
== Summary ==
This change proposal is to route all audio from PulseAudio and JACK to
the PipeWire Audio
daemon by default.
== Owner ==
* Name: [[User:Wtaymans| Wim Taymans]]
* Email: wim.taymans(a)gmail.com
== Detailed Description ==
Currently, all desktop audio is handled by the PulseAudio daemon.
Applications make use of the
PulseAudio client library to communicate with the PulseAudio daemon
that mixes and manages the audio streams from the clients.
The desktop shell (gnome-shell) and the control panel
(gnome-control-panel) both use the
Pulseaudio client libraries to manage the volume and configuration of
the PulseAudio daemon.
This proposal is to replace the PulseAudio daemon with a functionally
compatible implementation
based on PipeWire. This means that all existing clients using the
PulseAudio client library
will continue to work as before, as well as applications shipped as Flatpak.
All PRO audio is handled with the JACK client library, which talks to
the JACK server. This
proposal will install a JACK client library replacement that talks
directly to PipeWire. All
existing PRO audio jack applications will then work on top of PipeWire.
For legacy ALSA clients, we will install an ALSA plugin that routes
the audio directly to
PipeWire.
With these 3 changes, all audio will be routed to PipeWire. There will
then be no more need to
install the PulseAudio and JACK daemons.
== Feedback ==
The owner of this proposal has been in context with both the
PulseAudio and JACK maintainers and community.
PipeWire is considered to be the successor of both projects.
== Benefit to Fedora ==
The end goal is to end up with one audio infrastructure for both
Desktop and Pro audio use cases.
This will end the fragmentation of the audio landscape.
Some of the benefits that PipeWire will bring:
* PRO Audio features
PipeWire can support both Desktop and PRO Audio use cases. PRO
Audio application tend to use
the JACK API and JACK daemon, which is hard to setup and integrates
poorly with the rest of
the system (and PulseAudio in particular).
With a replacement libjack library, PRO Audio application can run
directly on PipeWire and
integrate seamlessly with other ALSA and PulseAudio applications.
This would bring Fedora
closer to the experience of other operating systems.
* Flexibility/Integration
PipeWire is designed to be multiprocess. It separates the
processing of the multimedia graph
and the management into separate processes. This makes it possible
to better integrate with
the other system components or swap out the default policy for a
highly customized one (such as
for automotive or embedded). This is in contrast to PulseAudio,
which has all logic embedded
into the daemon with limited configuration options.
In the next phase we expect to greatly expand the user experience
and configuration of the
audio infrastructure with better integration throughout the system.
* Performance
PipeWire was designed for high performance and low-latency, using
much of the same design as
JACK. JACK application should run with comparable performance even
in low-latency situations.
* Security
PipeWire enforces per client security. Object visibility and the
actions on them can be
configured independently per client. This makes it possible to
enforce a security policy for
sandboxed applications (Flatpak) such as denying access to certain
audio capture devices or
block them from interfering with other applications.
* Maintainability
Both PulseAudio and JACK have very slow development cycles with few
new features. The more
flexible and distributed nature of the design of PipeWire should
encourage more new features
and use-cases.
== Scope ==
* Proposal owners:
We would make a pipewire-pulse package that provides the same features
as the pulseaudio (daemon) package.
We would only provide a drop-in replacement daemon, the pulseaudio
client libraries will remain unchanged.
The idea is that when installing pipewire-pulse, only the pulseaudio
package is removed and replaced by the
pipewire-pulse implementation. In the same way, installing the
pulseaudio package would remove the pipewire-pulse
package, making it possible to switch between implementations. This
will also allow for an easy rollback.
We also need to check and correct the dependencies of other packages.
As of this writing, some packages do
not state their dependencies correctly and get removed when pulseaudio
is removed. We also need to check the
JACK to make sure they still install with the replacement JACK client library.
The JACK client libraries will be installed in the same way, removing
the old JACK client libraries.
* Other developers:
The distribution needs to default to the pipewire-pulse package
instead of pulseaudio.
JACK applications need to install the pipewire-libjack client library.
* Release engineering: [https://pagure.io/releng/issues #Releng issue
number] (a check of an impact with Release Engineering is needed)
* Policies and guidelines:
* Trademark approval: N/A (not needed for this Change)
== Upgrade/compatibility impact ==
The pulseaudio package will be uninstalled and pipewire-pulse will be installed.
pipewire-pulse does not yet implement all the features of pulseaudio
but it is expected that
comparable functionality will be implemented later. Most notable
features that are likely
not going to be available for fedora 34
* avahi network discovery and audio routing. This is not enabled by
default but can be activated
with paprefs. this includes TCP and RTP transport of audio.
* make devices available as UPNP media servers. Not enabled by
default, paprefs can be used.
* easy configuration of combining all sinks. Questionable feature but
possible via paprefs.
User scripts will still work but custom configurations of the
pulseaudio daemon will not be used
anymore.
Most of the JACK workflow of managing the JACK daemon is not going to
be needed anymore as things
will work out-of-the-box. As of this writing, these things are missing
from the JACK implementation,
we hope to implement them before fedora 34:
* latency reporting: useful to align streams
* freewheeling: used when rendering a project
* jackdbus: used by some tools to manage the graph
== How To Test ==
This change needs to be tested on as many different audio cards as
possible. The same test plan applies here as with PulseAudio.
To test, one needs to install the pipewire-pulse library (which
removes the pulseaudio package).
To test the JACK support, one needs to install pipewire-libjack, which
removes the original
JACK client and server.
After these changes, a restart is needed to make sure the new
pipewire-pulse daemon is running.
Audio functionality should be like it was before with the Pulseaudio
daemon. Some things to verify:
- patcl info should now list: Server Name: PulseAudio (on PipeWire 0.3.x)
- gnome-control-center: check the audio tab, check the volume sliders
and do the audio channel test. Change the card profile, plug/unplug
headphones and observe correct
switch.
- pavucontrol: check volumes in the input devices tabs and check the
microphone volumes
- firefox: check out a website with audio/video such as youtube and
verify that audio works as
usual. Check out a website with a video chat test page
(bluejeans.com/111).
- rhythmbox: check if playback works as expected
- bluetooth devices, connect as usual and verify working behaviour
with PipeWire. Check volume changes etc.
- Regular system usage and performance should not change.
- JACK tools such as catia, carla should run and can be used to
inspect the graph.
== User Experience ==
In general, users should not be able to see any change when using
PulseAudio applications.
The big change is when using JACK application:
- They will start without having to configure and start the daemon.
this includes
the period size and sample rates.
- All devices will be visible in the graph with meaningful names. Devices will
be automatically slaved when needed without needing any configuration.
- bluetooth devices will be usable as well.
== Dependencies ==
Other packages might need to have their requirements fixed to work
with the replacement packages
but this is under our control.
== Contingency Plan ==
* Contingency mechanism: Keep existing pulseaudio and JACK client
libraries as defaults
* Contingency deadline: beta freeze
* Blocks release? No
* Blocks product? No
== Documentation ==
