F37 proposal: GNU Toolchain Update (glibc 2.36, binutils 2.38) (late System-Wide Change proposal)
https://fedoraproject.org/wiki/Changes/GNUToolchainF37 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 == Update the Fedora 37 GNU Toolchain to glibc 2.36, binutils 2.38. The set of core GNU Toolchain packages for Fedora 37 are as follows: * GNU C Compiler 12 (first released in Fedora 36) ** Associated runtimes for C++ (libstdc++), Go (gccgo), OpenMP (gomp), Fortran (gfortran), D (phobos), Objective C/C++. * GNU Binary Utilities 2.38 (expected release in Fedora 37) * GNU C Library 2.36 (expected release in Fedora 37) * GNU Debugger 12 (immediately available in Fedora 35, 36, and 37) The glibc 2.36 change will be tracked in this top-level GNU Toolchain system-wide update. The binutils 2.38 change will be tracked in this top-level GNU Toolchain system-wide update. == Owner == * Name: [[User:codonell|Carlos O'Donell]] * Email: car...@redhat.com == Detailed Description == The GNU Compiler Collection, GNU C Library, GNU Debugger, and GNU Binary Utilities make up the core part of the GNU Toolchain and it is useful for our users to transition these components as a complete implementation when making a new release of Fedora. The GNU C Library version 2.36 is expected to be released in the beginning of August 2022; we have started closely tracking the glibc 2.36 development code in Fedora Rawhide and are addressing any issues as they arise. Given the present schedule Fedora 37 will branch after the release of glibc 2.36. However, the mass rebuild schedule means Fedora 37 will mass rebuild (if required) before the final release of glibc 2.36, but after the ABI is frozen. The GNU Binutils version 2.38 was released in February 2022; and we have already been using this version of binutils in Fedora Rawhide successfully to build the distribution. Given the present schedule for Fedora 37 we will continue to use Binutils 2.38 for Fedora 37. == Benefit to Fedora == Stays up to date with latest features, improvements, security and bug fixes from gcc, glibc, binutils, and gdb upstream. The goal is to track and transition to the latest components of the GNU Toolchain. == Scope == * Proposal owners: Fedora Toolchain Team (gcc, glibc, binutils, gdb, ...) developers need to ensure that gcc, glibc, binutils, and gdb in rawhide are stable and ready for the Fedora 37 branch. * Other developers: Given that glibc is backwards compatible and we have been testing the new glibc in rawhide it should make very little impact when updated, except for the occasional deprecation warnings and removal of legacy interfaces from public header files. * Release engineering: A mass rebuild is strongly encouraged; [https://pagure.io/releng/issue/10865 #10865] * 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 == Any source level changes required for glibc 2.36 will be noted here: https://sourceware.org/glibc/wiki/Release/2.36#Packaging_Changes == How To Test == The GNU Compiler Collection has its own testsuite which is run during the package build and examined by the gcc developers before being uploaded. The GNU C Library has its own testsuite which is run during the package build and examined by the glibc developers before being uploaded. This test suite has over 6200 tests that run to verify the correct operation of the library. In the future we may also run the microbenchmark to look for performance regressions. The GNU Binutils has its own testsuite which is run during the package build and examined by binutils developers before being uploaded. The regression testsuite is run to verify the correct operation of the static linker and attendant utilities. The GNU Debugger has its own testsuite which is run during the package build and examined by gdb developers before being uploaded. The regression testsuite is run to verify the correct operation of the debugger. == User Experience == == Dependencies == All packages do not need to be rebuilt due to backwards compatibility. However, it is advantageous if a mass rebuild is performed during the Fedora 37 cycle. The mass rebuild would ensure all packages can be built with the newer compiler and core runtime. == Contingency Plan == * Contingency mechanism glibc: If glibc 2.36 proves too disruptive to compiling the distribution we could revert to 2.35, but given that Rawhide has started tracking glibc 2.36, no show-stopper problems are expected. At this point we can still revert to upstream version 2.35 if insurmountable problems appear, but to do so may require a mass rebuild to remove new symbols from the ABI/API. * Contingency mechanism binutils: If binutils 2.38 proves too distruptive to assembling and linking the distribution we could
F37 proposal: Linux Firmware Minimization (late System-Wide Change proposal)
https://fedoraproject.org/wiki/Changes/Linux_Firmware_Minimization 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 == Split linux-firmware into more subpackages, and add the ability to automatically install firmware based on the hardware present == Owner == * Name: [[User:Salimma|Michel Alexandre Salim]], [[User:Dcavalca|Davide Cavalca]] * Email: mic...@fb.com, dcava...@fb.com == Detailed Description == The `linux-firmware` RPM is very large (175M src.rpm, 287M *.noarch.rpm per 20211027-126) that bundles most of the system firmware loaded by the kernel, regardless of whether it’s actually needed. Some additional firmwares are already split up into individual subpackages. This change would extend that, splitting out most firmare into appropriate subpackages. The Change would also make the subpackages `Supplements` the appropriate `modalias(...)` for the hardware they support and `Provides` `firmware(kmodname/firmwarefile.bin)` Candidates for splitting out: * CPU firmwares * GPU firmwares * Non-Intel wifi firmwares * Bluetooth firmwares Conversely some firmware could probably be grouped together, e.g. have iwlwifi-firmware that pulls in iwl*-firmware (corresponding to openSUSE's kernel-firmware-iwlwifi). We will also introduce `linux-firmware-all` that will pull in all subpackages; this will make it easier to manage the firmware packages in different Fedora variants. A DNF plugin will be written to make use of the `Supplements` metadata to automatically install the appropriate firmware packages based on the hardware present on the system (see openSUSE's `libzypp`: https://github.com/openSUSE/libzypp/blob/a34d857dbe3b16d4a7e0219cd213cc5a87966538/zypp/target/modalias/Modalias.cc and https://github.com/openSUSE/libzypp/blob/7f345ea4892fd02345e8de47c2a08ab5b174650b/doc/autoinclude/Modalias.doc) == Feedback == == Benefit to Fedora == This would save a lot of disk space on Fedora installations, and make it easier to test individual firmware updates by replacing a single subpackage. It will also bring us into alignment with openSUSE (see their [https://code.opensuse.org/package/kernel-firmware/blob/master/f/kernel-firmware.spec kernel-firmware.spec]). == Scope == * Proposal owners: ** Create test COPR with proposed changes ** Add some additional firmware subpackages ** Add the required metadata (supplements, provides) ** Write DNF plugin to make use of supplements ** Write libdnf plugin for PackageKit (and in the future, microdnf) ** refactor [https://pagure.io/fedora-comps/blob/main/f/comps-f37.xml.in#_2887-2903 comps for F37] * Other developers: ** Validate that installation works with iwl*-firmware replaced by iwlwifi-firmware ** Test the DNF plugin ** If it works well, preinstall the DNF plugin and stop installing iwlwifi-firmware or any of the iwl*-firmware * 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 == No compatibility impact. == How To Test == * Enable the test COPR * Verify that after upgrading, no firmware subpackages are removed * Install the DNF plugin * Verify that the DNF plugin works: `dnf mark remove` a firmware package that is needed, then verify that `dnf autoremove` does not remove it * `dnf mark remove` all firmware packages, and verify that `dnf autoremove` only remove the unneeded packages == User Experience == More disk space available, no functional changes. == Dependencies == No dependency, `linux-firmware` is not required by any package == Contingency Plan == * Contingency mechanism: If the plugin is not ready in time, the other changes would preserve the status quo. So we can postpone shipping the DNF plugin to F38. * Contingency deadline:Decide on whether to postpone the DNF plugin by beta freeze * Blocks release? No == Documentation == Documentation will be added in [https://hackmd.io/KnHbJ40pQ8eJjc1H80R10w this HackMD] == Release Notes == -- Ben Cotton He / Him / His Fedora Program Manager Red Hat TZ=America/Indiana/Indianapolis ___ devel-announce mailing list -- devel-announce@lists.fedoraproject.org To unsubscribe send an email to devel-announce-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel-announce@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
[HEADS UP] Sphinx 5 and docutils 0.18.1 coming to Rawhide on July 11th
Hello packagers, The new major version of the popular documentation framework Sphinx has been recently released[0]. It brings many changes, among which there is support of docutils 0.18.1. We aim to update both packages together in Fedora Rawhide on **July 11th**. As usual, an ongoing attempt to smoothly integrate the updates takes place using Copr[1]. There are some packages impacted with the new changes. Please take time to review an fix the package, or coordinate with the upstream. If your package hasn't succeeded to build with Python 3.11 yet, we can't test whether it will work with this update. Common issues and mitigation - `None` is no longer accepted as value of `language` in conf.py Solution: Use `language = 'en'` instead. - Build/ tests fail with: `AttributeError: 'path' object has no attribute 'text'` Solution: use `path.read_text()` instead Test your package locally in mock using the provided test Copr $ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/sphinx-5/fedora-rawhide-x86_64/ --no-clean $ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/sphinx-5/fedora-rawhide-x86_64/ shell Packages that pin Sphinx and docutils to lower versions than are about to be introduced, and will effectively stop working after the update has reached Rawhide: Sphinx < 5: python-h2-0:4.1.0-7.fc37.src python-priority-0:2.0.0-7.fc37.src python-sphinx-panels-0:0.6.0-3.fc37.src python-sphinx-tabs-0:3.1.0-7.fc37.src python3-sphinxcontrib-zopeext-0:0.3.2-3.fc37.noarch docutils < 0.18: python-sphinx-tabs-0:3.1.0-7.fc37.src python3-sphinx_rtd_theme-0:1.0.0-6.fc37.noarch Full list of known affected packages Maintainers by package: copr-keygen clime dturecek frostyx msuchy praiskup coq amdunn jjames diceware kushal kea fjanus mosvald zdohnal libcamerajavierm liblognorm alakatos rsroka zfridric python-djangobkabrda churchyard jdornak mrunge rdopiera salimma sgallagh python-graphviz eclipseo python-h2eclipseo python-pikepdf qulogic zdohnal python-priority eclipseo python-sphinx-panels qulogic python-sphinx-tabs hobbes1069 python-sphinx_rtd_theme jjames ksurma piotrp python-sphinxcontrib-bibtex jjames python-sphinxcontrib-htmlhelp churchyard cstratak python-sphinxcontrib-jsmath churchyard cstratak python-sphinxcontrib-qthelp churchyard cstratak python-sphinxcontrib-zopeext jjames Packages by maintainer: alakatos liblognorm amdunn coq bkabrdapython-django churchyard python-django python-sphinxcontrib-htmlhelp python-sphinxcontrib-jsmath python-sphinxcontrib-qthelp clime copr-keygen cstratak python-sphinxcontrib-htmlhelp python-sphinxcontrib-jsmath python-sphinxcontrib-qthelp dturecek copr-keygen eclipseo python-graphviz python-h2 python-priority fjanus kea frostyxcopr-keygen hobbes1069 python-sphinx-tabs javiermlibcamera jdornakpython-django jjames coq python-sphinx_rtd_theme python-sphinxcontrib-bibtex python-sphinxcontrib-zopeext ksurma python-sphinx_rtd_theme kushal diceware mosvaldkea mrunge python-django msuchy copr-keygen piotrp python-sphinx_rtd_theme praiskup copr-keygen qulogicpython-pikepdf python-sphinx-panels rdopiera python-django rsroka liblognorm salimmapython-django sgallagh python-django zdohnalkea python-pikepdf zfridric liblognorm Cheers, Karolina Surma [0] https://www.sphinx-doc.org/en/master/changes.html [1] https://copr.fedorainfracloud.org/coprs/ksurma/sphinx-5/ ___ devel-announce mailing list -- devel-announce@lists.fedoraproject.org To unsubscribe send an email to devel-announce-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel-announce@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
