Possible glibc 2.38 posix_memalign regression

There seems a performance regression of posix_memalign in Glibc-2.38. More info here: 30723 – Poor posix_memalign performance with long free lists

Workarounds:

You can try another malloc like mimalloc or jemalloc as workaround. Install mimalloc and start mpv with:

LD_PRELOAD=/usr/lib/libmimalloc.so mpv

or

LD_PRELOAD=/usr/lib/libjemalloc.so mpv

For folks that dont want to change things too much … an apparent workaround is to set a lowish cache size:

mkdir -p ~/.config/mpv && printf '\ndemuxer-max-bytes=50MiB\ndemuxer-max-back-bytes=25MiB\n' | tee -a ~/.config/mpv/mpv.conf
budgie-desktop >= 10.7.2-6 update requires manual intervention

When upgrading from budgie-desktop 10.7.2-5 to 10.7.2-6, the package mutter43 must be replaced with magpie-wm, which currently depends on mutter. As mutter43 conflicts with mutter, manual intervention is required to complete the upgrade.

First remove mutter43, then immediately perform the upgrade. Do not relog or reboot between these steps.

pacman -Rdd mutter43
pacman -Syu

Steam crashes on startup with lib32-libgudev installed

The latest lib32-libgudev update does not cooperate with the version of the same package provided by steam, and steam seems to attempt making calls to both leading to the crash.

Details: bug report, arch task, arch forum thread.

  • Workaround #1 (causes steam to avoid making any calls to lib32-libgudev by using a different library altogether)

    • sudo pacman -S lib32-libnm

  • Workaround #2 (forces steam and any other application to always use the new lib32-libgudev)

    • sudo pacman -S lib32-libudev0-shim

  • Workaround #3 (use steam-native-runtime, which doesn’t have the issue)

    • sudo pacman -S steam-native-runtime

TeX Live package reorganization

2023-06-18 - Antonio Rojas

Starting from version 2023.66594-9, TeX Live packages have been reorganized to mirror upstream collections. Even though the new texlive-basic replaces the old texlive-core, many of the texlive-core contents (including language specific files) are now split between different packages. To find out which Arch package contains a specific CTAN package, you can use the tlmgr utility, eg.

$ tlmgr info euler | grep collection
collection:  collection-latexrecommended

which means the euler CTAN package is contained in texlive-latexrecommended. You may also use pacman -F to query for specific files.

A new metapackage texlive-meta is available to install all subpackages (except for language specific ones), and the new texlive-doc package provides the full documentation for offline use.

The "community" repository has been merged into "extra" and is now empty

The [community] repository has been merged into [extra] and is now empty. It may take a bit of time for mirrors to catch up.

:point_right: Update your system and merge the pacman pacnew /etc/pacman.conf.pacnew file.

sudo pacman -Syu "pacman>=6.0.2-11"
OpenBLAS >= 0.3.23-2 update requires manual intervention

2023-06-14 - Felix Yan

The openblas package prior to version 0.3.23-2 doesn’t ship optimized LAPACK routine and CBLAS/LAPACKE interfaces for compatibility. This decision has been reverted now, and the ability to choose a different default system BLAS/LAPACK implementation while keeping openblas installed is now provided to allow future co-installation of BLIS, ATLAS, etc.

The default BLAS implementation will be used for most packages like NumPy or R. Please install blas-openblas and blas64-openblas to make OpenBLAS the default BLAS implementation, just like the old behavior.

Unfortunately you will get errors on updating if you currently have OpenBLAS installed as the default BLAS implementation:

error: failed to prepare transaction (could not satisfy dependencies)
:: installing openblas (0.3.23-2) breaks dependency 'blas' required by cblas
:: installing openblas (0.3.23-2) breaks dependency 'blas' required by lapack

Please append your preferred default BLAS implementation to the regular -Syu command line to get around it. For example:

sudo pacman -Syu blas-openblas

or

sudo pacman -Syu blas

Python 3.11 upgrade tip

Python packages built against python 3.10 can be rebuilt with the following:

pamac build $(pacman -Qoq /usr/lib/python3.10)
Pip package upgrade guide

If you have a lot of pip/AUR packages to upgrade to Python 3.11, read this.

If you installed python311 from the AUR, you need to uninstall it before running this update.

Many applications (firefox, thunderbird, etc) slow to start on desktops other than Gnome

Switch to the base-devel meta package requires manual intervention

2023-02-12 - Robin Candau

On February 2nd, the base-devel package group has been replaced by a meta package of the same name.
If you installed the base-devel package group prior to this date, explicitly re-install it to get the new base-devel package installed on the system:

pacman -Syu base-devel

PHP 8.2 update and introduction of legacy branch

2023-01-13 - Pierre Schmitz

The php packages have been updated to the latest version 8.2. In addition to this, a new set of php-legacy packages have been introduced. These will follow the oldest but still actively supported PHP branch. This enables users to install the latest version but also introduces the option to use third party applications that might rely on an older version. Both branches will be kept up to date following our rolling release model. php and php-legacy can be installed at the same time as the latter uses a -legacy suffix for its binaries and configuration files.

In addition to this, the php7 packages have been removed as they reached end of life. The imap extension will no longer be provided as it relies on the c-client library which has been abandoned for many years.

Some games like Dota 2 are freezing

The issue is caused by update libx11 1.8.3-4
The solution: Upgrade to libx11 1.8.3-5

VLC crashes when playing a video file

It looks like there has been a regression introduced with the new version of libva (2.17.0), which is used by VLC media player. If you get the following error when executing vlc in a terminal:

libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)

you may try to change the Output option in Preferences > Video to VDPAU output instead of Automatic (or whatever value it had been set to before).

Downgrading the libva package from 2.17.0-1 to 2.16.0-1 may also work, but it is a more short-term workaround that should not be kept for too long, as sooner or later, the older package won’t be compatible with the other packages. Consider to do the solution above first.
