FESCo wants to know what you use i686 packages for
by David Cantrell
Hi,
Our most recent FESCo meeting involved discussing the proposal to drop i686
builds of jdk8,11,17 from Fedora 37 onward. The topic quickly changed to the
larger question of "what do people use i686 packages for?"
Rather than guess, we wanted to ask the community what you use i686 packages
for in Fedora. There are no wrong answers here. We are seeking information.
Why? Since the removal of the i686 kernel in Fedora, we want to reduce the
number of i686 packages provided in the repo. As time marches on, the ability
to build a lot of things for i686 becomes unrealistic or even impossible.
Remember it goes beyond providing builds...providing support, bug fixes, and
security fixes for those packages too. Maybe some things using i686 packages
now can move to x86_64 packages. We do not know yet, but a goal is to figure
out what packages, if anything, can drop their i686 builds.
NOTE: Nothing is changing now. We are in an information gathering phase.
~~~~~~~~~~~~~~~~~~~~~~~~
If you use i686 packages for something now, please respond to this thread.
Thanks,

F39 proposal: Replace DNF with DNF5 (System-Wide Change proposal)
by Ben Cotton
https://fedoraproject.org/wiki/Changes/ReplaceDnfWithDnf5
This document represents a proposed Change. As part of the Changes
process, proposals are publicly announced in order to receive
community feedback. This proposal will only be implemented if approved
by the Fedora Engineering Steering Committee.
== Summary ==
Make DNF5 the new default packaging tool. The change will replace DNF,
LIBDNF, and DNF-AUTOMATIC with the new DNF5 and new Libdnf5 library.
It is a second step after
https://fedoraproject.org/wiki/Changes/MajorUpgradeOfMicrodnf.
== Owner ==
* Name: [[User:jmracek| Jaroslav Mracek]]
* Email: jmracek(a)redhat.com
== Detailed Description ==
The new DNF5 will provide a significant improvement in user
experiences and performance. The replacement is the second step in
upgrade of Fedora Software Management stack. Without the change there
will be multiple software management tool (DNF5, old Microdnf,
PackageKit, and DNF) based on different libraries (libdnf, libdnf5),
providing a different behavior, and not sharing a history. We can also
expect that DNF will have only limited support from upstream. The DNF5
development was announced on
[https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.o...
Fedora-Devel] list in 2020.
=== New DNF5 Features ===
* Fully featured package manager without requirement of Python
** Smaller system
** Faster
** Replace DNF and Microdnf
* Unified behavior of in the software management stack
** New Libdnf5 plugins (C++, Python) will be applicable to DNF5, Dnf5Daemon
*** DNF4 plugins were not applicable for PackageKit and Microdnf (e.g.
versionlock, subscription-manager), therefore PackageKit behaves
differently in comparison to DNF
** Shared configurations
*** In DNF4 not all configuration is honored by PackageKit and Microdnf
** DNF/YUM was developed for decades with impact of multiple styles
and naming conventions (options, configuration, options, commands)
* New Daemon
** The new daemon can provide an alternative to PackageKit for RPMs
(only one backend of PackageKit) if it will be integrated into Desktop
** Support of Modularity and Comps group
* Performance improvement
** Loading of repositories
** Advisory operations
** RPM queries
*** Name filters with a case-insensitive search (the `repoquery` command)
** Smart sharing of metadata between dnf5 and daemon
*** Reduce disk and downloads requirements
*** Currently, DNF, Microdnf, and PackageKit use their own cache
*** Optional, may be not available for Fedora 39
* Decrease of a maintenance cost in the long term
** Shared plugins
** Removal of functional duplicates
* Fully integrated Modularity in LIBDNF5 workflows
** The Modularity is supported in DNF and LIBDNF but it is not fully
integrated. Integration was not possible due to limitation of
compatibility with other tools (PackageKit)
** Fully integrated Modularity required changes in the library workflow
=== Major codebase improvements ===
*Reports in structure
** DNF reports a lot of important information only in logs
* Removal of duplicated implementation
** LIBDNF evolved from LIBHIF (PackageKit library) and HAWKEY (DNF
library). The integration was never finished, therefore LIBDNF still
contains duplicated functionality.
** decrease of the code maintenance cost in future
* Unify Python bindings
** Formal Libdnf provides two types of Python bindings
*** CPython (hawkey)
*** SWIG (libdnf)
** Maintaining and communication between both bindings requires a lot
of resources
** Binding unification was not possible without breaking API compatibility
* SWIG bindings
** With SWIG we can generate additional bindings without spending huge resources
** Code in particular languages will be very similar to each other
* Separation of system state from history DB and `/etc/dnf/module.d`
** In dnf-4 the list of userinstalled packages and list of installed
groups along with the lists of packages installed from them is
computed as an aggregation of transaction history. In dnf5 it will be
stored separately, having multiple benefits, among them that the
history database will serve for informational purposes only and will
not define the state of the system (it gets corrupted occasionally
etc.).
** Data stored in `/etc/dnf/module.d` were not supposed to be user
modifiable and their format is not sufficient (missing information
about installed packages with installed profiles)
*** Content of `/etc/dnf/module.d` will be moved into the System State
== Feedback ==
== Benefit to Fedora ==
== Scope ==
* Proposal owners:
DNF5 is still in the development and some of the features or options
are not yet available. We still have to finish the implementation of
Modularity, storing internal data related to History and System State,
and also documentation and man pages. DNF5 can be tested from
repository with upstream nightly builds -
https://copr.fedorainfracloud.org/coprs/rpmsoftwaremanagement/dnf5-unstable/.
The project's github repository is here -
https://github.com/rpm-software-management/dnf5/
* Other developers:
* Release engineering: [https://pagure.io/releng/issues #Releng issue number]
* Policies and guidelines: N/A (not needed for this Change)
* Trademark approval: N/A (not needed for this Change)
* Alignment with Objectives:
== Upgrade/compatibility impact ==
The new DNF5 will obsolete `dnf`, `yum`, `dnf-automatic`, `yum-utils`,
and DNF plugins (core and extras). python3-dnf and LIBDNF (`libdnf`,
`python3-hawkey`) will be obsoleted by `fedora-obsolete-packages`.
=== Compatibility ===
The new DNF5 will provide a symlink to `/usr/bin/dnf` therefore users
will see the replacement as an upgrade of DNF with limited but
documented syntax changes. The DNF5 will provide some compatible
aliases of commands and options to improve adoption of the DNF5.
== How To Test ==
Install `dnf5` package from
https://copr.fedorainfracloud.org/coprs/rpmsoftwaremanagement/dnf5-unstable/
== User Experience ==
* Improved progress bars
* Improved transaction table
* Transaction progress reports including scriptlets reports
* Support of local rpm for transaction operation
* Great bash completion (better then DNF has)
* New commands and options that are only available with `DNF`
== Dependencies ==
There is a long list of dependent packages

Donate 1 minute of your time to test upgrades from F36 to F37
by Miroslav Suchý
Do you want to make Fedora 37 better? Please spend 1 minute of your time and try to run:
# Run this only if you use default Fedora modules
# next time you run any DNF command default modules will be enabled again
sudo dnf module reset '*'
dnf --releasever=37 --setopt=module_platform_id=platform:f37 \
--enablerepo=updates-testing \
$(rpm -q fedora-repos-modular >/dev/null && echo --enablerepo=updates-testing-modular) \
--assumeno distro-sync
This command does not replace `dnf system-upgrade`, but it will reveal potential problems.
You may also run `dnf upgrade` before running this command.
The `--assumeno` will just test the transaction, but does not make the actual upgrade.
In case you hit dependency issues, please report it against the appropriate package.
Or against fedora-obsolete-packages if that package should be removed in Fedora 37. Please check existing reports against
fedora-obsolete-packages first:
https://red.ht/2kuBDPu
and also there is already bunch of "Fails to install" (F37FailsToInstall) reports:
https://bugzilla.redhat.com/buglist.cgi?bug_id=2045109&bug_id_type=anddep...
Thank you

"rescue" boot entry files are not updated on OS upgrades
by Chris Murphy
Summary----------
Most all Fedora variants (except Cloud) have a GRUB menu entry
containing the word "rescue". This kernel+initramfs pair are never
updated for the life of a Fedora installation. And they quickly become
stale as a Fedora installation ages. This kernel's modules are
eventually deleted, and if selected at boot time, the typical user
experience is a dracut shell.
Basic background-------------
(skip this section if you know how it works)
During a new installation, a single kernel version is installed. e.g.
vmlinuz-5.17.0-0.rc4.96.fc36.x86_64 which is then duplicated as e.g.
vmlinuz-0-rescue-3a86878de5d649a983916543ece7bb7e.
Each of those (identical) kernels has an initramfs file:
initramfs-5.17.0-0.rc4.96.fc36.x86_64.img
initramfs-0-rescue-3a86878de5d649a983916543ece7bb7e.img
The sole difference is the first one is a smaller host-only initramfs,
the second one is a larger no host-only initramfs created with `dracut
-N`. The bigger one just contains a bunch of extra kernel modules and
dracut scripts, ostensibly to make it more likely to boot a system
with some change in hardware that the host-only initramfs doesn't
contain. The size of this rescue initramfs is around 100 MiB, with the
common day to day "host only" initramfs being around 33 MiB. [1]
As the system is updated, additional kernel versions are installed.
dnf.conf contains installonly_limit=3, which results in a maximum of
three kernel versions being installed at a time. Once a fourth kernel
is installed, the first kernel and its modules are removed from
/usr/lib/modules. The rescue kernel+initramfs pair are never updated
or upgraded, even during system upgrades.
Observations------------
This has been discussed by the Workstation working group [2] but since
this functionality is present in all of Fedora, we're moving the
discussion for greater visibility.
There's two separate complaints, if you will: (a) that the
kernel+initramfs pair are never update or upgraded for the life of the
installation; and (b) that even during one release cycle, the user
experience when booting the rescue entry, changes, i.e. when the
matching /usr/lib/modules for the rescue entry are present early on,
you do get a full runtime behavior, you will get to a graphical
environment. But then once the version matched /usr/lib/modules are
removed, you get a completely different behavior when booting the
rescue entry.
An important note from that ticket from Justin Forbes, the Fedora
kernel maintainer: " Remember, the only real purpose of the rescue
kernel is to get your system out of something completely unusable. It
isn't meant to be a full runtime."
Questions------------
* Considering the very narrow purpose of the entry, maybe the current
behavior is adequate?
* Does the rescue entry reliably get users to a dracut prompt, rather
than indefinite hang? I don't know whether it does.
* Is there any way to improve the situation without increasing the
risk that the rescue entry becomes totally non-functional?
* The chosen kernel version needs to be based on one that is known
to boot. Currently we know the kernel+initramfs pair work because it's
the same version used to boot the installation media when doing the
initial provisioning. We don't actually know an updated replacement
"no host-only" initramfs will work until it's tried. Is it possible to
automate this? And is it worth the risk, or even figuring out how to
assess the risk?
* At Flock 2021, Zbyszek proposed "Building Initrd Images from
RPMs" to reduce the complexity of building initramfs, maybe there's a
role for it here? More: https://www.youtube.com/watch?v=GATg_bqmASc
* What happens if we accept some scope creep, and go for many
improvements that make the extra work worth it?
* What about the unsigned nature of the initramfs? Should we be
creating initramfs's in Fedora infra and signing them?
* Stuff a graphical rescue environment into the initramfs? (This
might be ten leaps too far, but it's intended to encourage thinking
with a vivid imagination.)

F38 proposal: Node.js Repackaging (Self-Contained Change proposal)
by Ben Cotton
https://fedoraproject.org/wiki/Changes/NodejsRepackaging
This document represents a proposed Change. As part of the Changes
process, proposals are publicly announced in order to receive
community feedback. This proposal will only be implemented if approved
by the Fedora Engineering Steering Committee.
== Summary ==
We are reworking the Node.js packaging to make Node.js versions
available as parallel-installable packages.
== Owner ==
* Name: [[User:SGallagh| Stephen Gallagher]]
* Email: sgallagh(a)redhat.com
== Detailed Description ==
We will be creating the packages nodejs-16, nodejs-18 and (in April)
nodejs-20. These packages will be parallel-installable (with the
exception of the -devel subpackages) and provide
`/usr/bin/node-$MAJOR`. We will also take advantage of the
`alternatives` subsystem to populate `/usr/bin/node` from the default
Node.js version for that release, or if the default is not installed,
the highest currently-installed version.
Notes:
* The default in Fedora 38 will be Node.js 18. If a user was to
install Node.js 16 and Node.js 20, but not Node.js 18, then Node.js 20
would provide `/usr/bin/node`
* The policy going forward will be to have the most recently-released
version of Node.js at the time of Fedora's expected Beta release date
be the default for that release throughout its lifetime.
== Feedback ==
[https://lists.fedoraproject.org/archives/list/nodejs@lists.fedoraproject....
Mailing list thread]
Neal Gompa raised the question of using a subpackage to own
`/usr/bin/node` instead of using the `alternatives` subsystem, citing
python as an example. My response was that the problem with this is
that I want `/usr/bin/node` to always be available so long as any
`nodejs-$MAJOR` version is installed. It also ensures that the
`node(1)` manpage always matches the `/usr/bin/node` executable.
== Benefit to Fedora ==
=== User Benefits ===
* Provides a simple way to have a different (or multiple) Node.js
interpreters on their system. No dealing with Modularity.
* Enables multiple versions of Node.js on the system (can test code
against different versions without using containers)
=== Packager Benefits ===
* No more modules to maintain.
* Availability of multiple Node.js versions in the buildroot means
that other `nodejs-*` packages can test against multiple supported
options.
== Scope ==
* Proposal owners:
The packaging work is done and can be played with at
https://copr.fedorainfracloud.org/coprs/sgallagh/nodejs-alternatives/
today.
* Other developers:
There should be no need to change any dependent packages, though
packagers of Node.js software may wish to take advantage of the
testing opportunities afforded.
* Release engineering:
* Policies and guidelines: We will be updating the Node.js Packaging
Guidelines with the new best practices.
* Trademark approval: N/A (not needed for this Change)
* Alignment with Objectives: N/A
== Upgrade/compatibility impact ==
Systems using the existing nodejs RPM package will be upgraded to the
matching `nodejs-$MAJOR` version. Work is pending on how to migrate
users of Modular Node.js to the new packages.
== How To Test ==
== User Experience ==
Done correctly, this should be handled entirely without the user's
need to know about it.
== Dependencies ==
== Contingency Plan ==
* Contingency mechanism: (What to do? Who will do it?) N/A (not a
System Wide Change)
* Contingency deadline: N/A (not a System Wide Change)
* Blocks release? N/A (not a System Wide Change)
== Documentation ==
https://lists.fedoraproject.org/archives/list/nodejs@lists.fedoraproject....
== Release Notes ==
Multiple releases of Node.js may now be installed in parallel from the
Fedora repositories.

F37 proposal: Add -fno-omit-frame-pointer to default compilation
flags (System-Wide Change proposal)
by Ben Cotton
https://fedoraproject.org/wiki/Changes/fno-omit-frame-pointer
This document represents a proposed Change. As part of the Changes
process, proposals are publicly announced in order to receive
community feedback. This proposal will only be implemented if approved
by the Fedora Engineering Steering Committee.
== Summary ==
Fedora will add -fno-omit-frame-pointer to the default C/C++
compilation flags, which will improve the effectiveness of profiling
and debugging tools.
== Owner ==
* Name: [[User:daandemeyer| Daan De Meyer]], [[User:Dcavalca| Davide
Cavalca]], [[ Andrii Nakryiko]]
* Email: daandemeyer(a)fb.com, dcavalca(a)fb.com, andriin(a)fb.com
== Detailed Description ==
Credits to Mirek Klimos, whose internal note on stacktrace unwinding
formed the basis for this change proposal (myreggg(a)gmail.com).
Any performance or efficiency work relies on accurate profiling data.
Sampling profilers probe the target program's call stack at regular
intervals and store the stack traces. If we collect enough of them, we
can closely approximate the real cost of a library or function with
minimal runtime overhead.
Stack trace capture what’s running on a thread. It should start with
clone - if the thread was created via clone syscall - or with _start -
if it’s the main thread of the process. The last function in the stack
trace is code that CPU is currently executing. If a stack starts with
[unknown] or any other symbol, it means it's not complete.
=== Unwinding ===
How does the profiler get the list of function names? There are two parts of it:
# Unwinding the stack - getting a list of virtual addresses pointing
to the executable code
# Symbolization - translating virtual addresses into human-readable
information, like function name, inlined functions at the address, or
file name and line number.
Unwinding is what we're interested in for the purpose of this
proposal. The important things are:
* Data on stack is split into frames, each frame belonging to one function.
* Right before each function call, the return address is put on the
stack. This is the instruction address in the caller to which we will
eventually return — and that's what we care about.
* One register, called the "frame pointer" or "base pointer" register
(RBP), is traditionally used to point to the beginning of the current
frame. Every function should back up RBP onto the stack and set it
properly at the very beginning.
The “frame pointer” part is achieved by adding push %rbp, mov
%rsp,%rbp to the beginning of every function and by adding pop %rbp
before returning. Using this knowledge, stack unwinding boils down to
traversing a linked list:
https://i.imgur.com/P6pFdPD.png
=== Where’s the catch? ===
The frame pointer register is not necessary to run a compiled binary.
It makes it easy to unwind the stack, and some debugging tools rely on
frame pointers, but the compiler knows how much data it put on the
stack, so it can generate code that doesn't need the RBP. Not using
the frame pointer register can make a program more efficient:
* We don’t need to back up the value of the register onto the stack,
which saves 3 instructions per function.
* We can treat the RBP as a general-purpose register and use it for
something else.
Whether the compiler sets frame pointer or not is controlled by the
-fomit-frame-pointer flag and the default is "omit", meaning we can’t
use this method of stack unwinding by default.
To make it possible to rely on the frame pointer being available,
we'll add -fno-omit-frame-pointer to the default C/C++ compilation
flags. This will instruct the compiler to make sure the frame pointer
is always available. This will in turn allow profiling tools to
provide accurate performance data which can drive performance
improvements in core libraries and executables.
== Feedback ==
=== Potential performance impact ===
* Meta builds all its libraries and executables with
-fno-omit-frame-pointer by default. Internal benchmarks did not show
significant impact on performance when omitting the frame pointer for
two of our most performance intensive applications.
* Firefox recently landed a change to preserve the frame pointer in
all jitted code
(https://bugzilla.mozilla.org/show_bug.cgi?id=1426134). No significant
decrease in performance was observed.
* Kernel 4.8 frame pointer benchmarks by Suse showed 5%-10%
regressions in some benchmarks
(https://lore.kernel.org/all/20170602104048.jkkzssljsompjdwy@suse.de/T/#u)
Should individual libraries or executables notice a significant
performance degradation caused by including the frame pointer
everywhere, these packages can opt-out on an individual basis as
described in https://docs.fedoraproject.org/en-US/packaging-guidelines/#_compiler_flags.
=== Alternatives to frame pointers ===
There are a few alternative ways to unwind stacks instead of using the
frame pointer:
* [https://dwarfstd.org DWARF] data - The compiler can emit extra
information that allows us to find the beginning of the frame without
the frame pointer, which means we can walk the stack exactly as
before. The problem is that we need to unwind the stack in kernel
space which isn't implemented in the kernel. Given that the kernel
implemented it's own format (ORC) instead of using DWARF, it's
unlikely that we'll see a DWARF unwinder in the kernel any time soon.
The perf tool allows you to use the DWARF data with
--call-graph=dwarf, but this means that it copies the full stack on
every event and unwinds in user space. This has very high overhead.
* [https://www.kernel.org/doc/html/v5.3/x86/orc-unwinder.html ORC]
(undwarf) - problems with unwinding in kernel led to creation of
another format with the same purpose as DWARF, just much simpler. This
can only be used to unwind kernel stack traces; it doesn't help us
with userspace stacks. More information on ORC can be found
[https://lwn.net/Articles/728339 here].
* [https://lwn.net/Articles/680985 LBR] - New Intel CPUs have a
feature that gives you source and target addresses for the last 16 (or
32, in newer CPUs) branches with no overhead. It can be configured to
record only function calls and to be used as a stack, which means it
can be used to get the stack trace. Sadly, you only get the last X
calls, and not the full stack trace, so the data can be very
incomplete. On top of that, many Fedora users might still be using
CPUs without LBR support which means we wouldn't be able to assume
working profilers on a Fedora system by default.
To summarize, if we want complete stacks with reasonably low overhead
(which we do, there's no other way to get accurate profiling data from
running services), frame pointers are currently the best option.
== Benefit to Fedora ==
Implementing this change will provide profiling tools with easy access
to stacktraces of installed libraries and executables which will lead
to more accurate profiling data in general. This in turn can be used
to implement optimizations to core libraries and executables which
will improve the overall performance of Fedora itself and the wider
Linux ecosystem.
Various debugging tools can also make use of the frame pointer to
access the current stacktrace, although tools like gdb can already do
this to some degree via embedded dwarf debugging info.
== Scope ==
* Proposal owners: Put up a PR to change the rpm macros to build
packages by default with -fno-omit-frame-pointer by default.
* Other developers: Review and merge the PR implementing the Change.
* Release engineering: [https://pagure.io/releng/issues #Releng issue
number]. A mass rebuild is required.
* Policies and guidelines: N/A (not needed for this Change)
* Trademark approval: N/A (not needed for this Change)
* Alignment with Objectives: N/A
== Upgrade/compatibility impact ==
This should not impact upgrades in any way.
== How To Test ==
# Build the package with the updated rpm macros
# Profile the binary with `perf record -g <binary>`
# Inspect the perf data with `perf report -g 'graph,0.5,caller'`
# When expanding hot functions in the perf report, perf should show
the full call graph of the hot function (at least for all functions
that are part of the binary compiled with -fno-omit-frame-pointer)
== User Experience ==
Fedora users will be more likely to have a streamlined experience when
trying to debug/profile system executables/libraries. Tools such as
perf will work out of the box instead of requiring to users to provide
extra options (e.g. --call-graph=dwarf/LBR) or requiring users to
recompile all relevant packages with -fno-omit-frame-pointer.
== Dependencies ==
The rpm macros for Fedora need to be adjusted to include
-fno-omit-frame-pointer in the default C/C++ compilation flags.
== Contingency Plan ==
* Contingency mechanism: The new version can be released without every
package being rebuilt with fno-omit-frame-pointer. Profiling will only
work perfectly once all packages have been rebuilt but there will be
no regression in behavior if not all packages have been rebuilt by the
time of the release. If the Change is found to introduce unacceptable
regressions, the PR implementing it can be reverted and affected
packages can be rebuilt.
* Contingency deadline: Final freeze
* Blocks release? No
== Documentation ==
* Original proposal for in-kernel DWARF unwinder (rejected):
https://lkml.org/lkml/2017/5/5/571
== Release Notes ==
Packages are now compiled with frame pointers included by default.
This will enable a variety of profiling and debugging tools to show
more information out of the box.

Updating asio in rawhide (and possibly F37) to 1.24.0
by Julian Sikorski
Dear maintainers,
I have updated Fedora asio package from the current 1.16.1 to 1.24.0. I
have rebuilt the seven current dependencies and with the exception of
OpenSceneGraph, all build fine against the updated asio package. While
OpenSceneGraph failed to build, the failure does not seem to have to do
anything with asio.
I have created a side tag so that the rebuilds can be coordinated:
f38-build-side-56604. I do not have provenpacker privileges which means
you have to request the rebuilds yourself. You can start once the asio
build [1] finishes. Thank you for your cooperation in advance.
Best regards,
Julian
