repro only uses one core to build about archlinux-repro HOT 10 CLOSED

Two folded. /usr/share/devtools doesn't set it. If anything it is read from ~/.makepkg.conf and do you want us to just set MAKEPKG="-j$(nproc)" by default in the container?

from archlinux-repro.

I think repro should do the same as devtools and keep {SRC,SRCPKG,PKG,LOG}DEST, MAKEFLAGS and PACKAGER from the host makepkg.conf.

from archlinux-repro.

@FFY00 There is no host makepkg.conf. Repro does not assume an Arch LInux host, which is why it goes through the current troubles.

from archlinux-repro.

Check in /etc/makepkg.conf and then ~/.makepkg.conf. Is there anyone conflicting with us on /etc/makepkg.conf?

from archlinux-repro.

Well yes. Pacman is packaged in several distros. I'd rather supply nproc or allow MAKEFLAGS env variables then providing a makepkg.conf file

from archlinux-repro.

Yes, and why is it not acceptable to read /etc/makepkg.conf if we document it?

And sorry, I messed up the order. I meant check ~/.makepkg.conf first and then fallback to /etc/makepkg.conf.

The issue of defaulting to one core is that it's going to become a common gotcha because this becomes an extra step in the setup instructions of a rebuilder. People running rebuilders shouldn't be required to have the same level of experience as packagers.

from archlinux-repro.

If packagers can't deal with this then we are all doomed.

I am not thinking of any major reason why we couldn't read /etc/makepkg.conf in other distributions, at least for getting MAKEFLAGS. If this is really a problem then we can add a build system flag to disable this behavior.

But anyway, it isn't a big deal.

from archlinux-repro.

Repro isn't suppose to be used by packagers. But by users that want to reproduce their packages.

from archlinux-repro.

Right, very well.

I still think a build system flag to enable/disable this behavior is a good solution.

But maybe we should just default to -j$(nproc) as a user should not be expected to edit a makepkg.conf to get large builds to not take forever.
