Release Notes for Alpine 3.12.0

ncurses fixes

A few fixes trickled in relating exclusively to Alpine Linux that affect ncurses:

- ncurses-libs no longer depend on the 7.5 MB ncurses-terminfo, instead depending only on the 120 kB ncurses-terminfo-base. - ncurses-terminfo-base now includes the most common terminfo databases like tmux, screen, xterm-256color and also databases

for packaged terminals like gnome-terminal, vte, konsole, alacritty, kitty, putty. All other terminfo databases are now
in ncurses-terminfo.

- All terminals now depend on ncurses-terminfo-base if it provides the terminfo database for the terminal.

python3 no longer provides pip3, use py3-pip from community

Python3 is now built with --without-ensurepip which removes pip3 and its libraries from it. Instead use the py3-pip pacakge which uses system components.

BPF JIT support

> TODO: Small preamble about BPF

So it (BPF JIT) has been enabled by default in 3bf2313adc57fe6b36bf459ddca6d65a392609db, and unprivileged BPF JIT has been disabled in 4e286992d5ed751f6ca60eb18d77313bb0868513.

OpenRC now has a sane ordering of directories when configuring kernel parameters

Configuring kernel parameters is done by having configuration files in specific locations like /etc/sysctl.conf and files ending with .conf in certain directories like /etc/sysctl.d. Before 3.12.0 the ordering had no logical explanation and surprised users that expected a hierarchy.

Starting with 3.12.0 the ordering is as follows:

1. /lib/sysctl.d/*.conf
2. /usr/lib/sysctl.d/*.conf
3. /run/sysctl.d/*.conf
4. /etc/sysctl.conf
5. /etc/sysctl.d/*.conf

/lib/sysctl.d and /usr/lib/sysctl.d are to be used by the distribution and packages. Alpine Linux installs its default configuration file in /lib/sysctl.d/00-alpine.conf. Software installed via our package manager will install to either of those places.

/run/sysctl.d holds configuration that is created at run-time by daemons/services or at very early-boot. Neither the distribution nor the packaged software will install configuration to it, primarily because /run is in temporary memory. Configuration in this location that matches names the locations used by the distribution and packages will cause the latter not to be read and applied by the sysctl service.

/etc/sysctl.d holds configuration that is created and maintained by the local administrator, neither Alpine nor its packaged software will touch it, and configuration in that has the same name as in the location reserved for the distribution and packages, or the location for run-time configuration from daemons/services, will cause the latter to not be read and applied by the sysctl service.

/etc/sysctl.conf is a historical location for this kind of configuration and is kept for the same reasons.

OpenRC now has a sane ordering of directories when loading kernel modules

Loading kernel modules during boot is done with the modules OpenRC service, which reads configuration files in certain locations and loads kernel modules with the modprobe utility from either busybox or util-linux.

Starting with 3.12.0 a more logical ordering is adopted for which configuration files to read and ignore:

1. /lib/modules-load.d/*.conf
2. /usr/lib/modules-load.d/*.conf
3. /run/modules-load.d/*.conf
4. /etc/modules
5. /etc/modules-load.d/*.conf

/lib/modules-load.d and /usr/lib/modules-load.d are to be used by the distribution and packages. Software installed via our package manager will install to either of those places.

/run/modules-load.d holds configuration that is created at run-time by daemons/services or at very early-boot. Neither the distribution nor the packaged software will install configuration to it, primarily because /run is in temporary memory. Configuration in this location that matches names in the locations used by the distribution and packages will cause the latter not to be read and applied by the modules service.

/etc/modules-load.d holds configuration that is created and maintained by the local administrator, neither Alpine nor its packaged software will touch it, and configuration in that has the same name as in the location reserved for the distribution and packages, or locations reserved for the run-time configuration of daemons/services, will cause the latter to not be read and applied by the modules service.

/etc/modules is a historical location for this kind of configuration and is kept for the same reasons.

Telegram Desktop is now available in the community repo

See commit that moved the package to the community repo for explanation.

efitools and sbsigntool are now in main/

Those packages have lived in testing/ for a long time and have been successfully used by one of our developers to implement secure-boot in his system. They have been moved to main/ and will be available for others.

abuild

Add default functions for subpackages that hold Bash, Zsh and Fish completion

abuild now provides default functions for $pkgname-bash-completion, $pkgname-zsh-completion and $pkgname-fish-completion subpackages.

Expected location of the completion files per shell:

• Bash -> /usr/share/bash-completion/completions
• Zsh -> /usr/share/zsh/site-functions
• Fish -> /usr/share/fish/completions

Files must be installed in the expected location in relation to $pkgdir in pacakge().

Introduced in d5826968b713123a4f51d3dec1adb1225d0e194f.

newapkbuild when called with CMake (-C) does out-of-source builds by default

When packaging with newapkbuild and using the -C switch to pre-fill the apkbuild with skeleton functions for CMake now:

• Adds -B build to the cmake call in build().
• Adds -C build the make calls.

Doing out-of-source builds are recommended upstream to the point where warnings are printed when calling CMake on a project.

Introduced in e125a764896d884c69cc409e614b65cb336c15e8.

set CARGO_HOME to cache dependencies of rust packages

CARGO_HOME is now set to $SRCDEST/cargo and will cache all dependencies downloaded.

Introduced in af0c88e6abbb1e49224759f5c51b3068e6eab28b.
