Hello pacman devs, today I installed a big package from the AUR on a clean system and forgot to adjust the makepkg.conf beforehand. As makepkg.conf is set up to compresses all packages with zstd before installing them onto the system the compression took a while. Because of that, I would like to add the -T0 flag to the list of default ZSTCOMPRESSION args. This would allow zstd to spawn multiple compression flags (equal to the number of physical processors) and thus speed up package compression. I have created a simple patch for this feature but as this is my first contribution to this project I am not entirely sure that I adjusted all necessary files: From 6a8d811fbced5a799d88ee357d4b0c694d79e0f7 Mon Sep 17 00:00:00 2001 From: Frederik Enste Date: Tue, 9 Feb 2021 22:43:56 +0100 Subject: [PATCH] added -T0 flag to default zstd compression Signed-off-by: Frederik Enste ---  doc/makepkg.conf.5.asciidoc | 2 +-  etc/makepkg.conf.in         | 2 +-  2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/doc/makepkg.conf.5.asciidoc b/doc/makepkg.conf.5.asciidoc index 04cc5ea9..40129a01 100644 --- a/doc/makepkg.conf.5.asciidoc +++ b/doc/makepkg.conf.5.asciidoc @@ -259,7 +259,7 @@ Options  **COMPRESSGZ=**"(gzip -c -f -n)"::  **COMPRESSBZ2=**"(bzip2 -c -f)"::  **COMPRESSXZ=**"(xz -c -z -)":: -**COMPRESSZST=**"(zstd -c -z -)":: +**COMPRESSZST=**"(zstd -c -z -T0 -)"::  **COMPRESSLZO**"(lzop -q)"::  **COMPRESSLRZ=**"(lrzip -q)"::  **COMPRESSLZ4=**"(lz4 -q)":: diff --git a/etc/makepkg.conf.in b/etc/makepkg.conf.in index b13b1d5d..8d655bf8 100644 --- a/etc/makepkg.conf.in +++ b/etc/makepkg.conf.in @@ -133,7 +133,7 @@ DBGSRCDIR="/usr/src/debug"  COMPRESSGZ=(gzip -c -f -n)  COMPRESSBZ2=(bzip2 -c -f)  COMPRESSXZ=(xz -c -z -) -COMPRESSZST=(zstd -c -z -q -) +COMPRESSZST=(zstd -c -z -q -T0 -)  COMPRESSLRZ=(lrzip -q)  COMPRESSLZO=(lzop -q)  COMPRESSZ=(compress -c -f) -- 2.30.0 Of course, I would understand if this "feature" is not important or requested by other users as everybody could change the makepkg.conf in seconds but please let me know what you think about this.
