Hi.
I might have an idea how to make building Perl packages faster and their
buildroot a little bit smaller.
perl-devel depends on systemtap-sdt-devel and that package contains a
single script written in Python and using pycparser. The single script
bring python3-pycparser and therefore the whole Python with its standard
library to the buildroot of all perl packages although (according to my
testing) none of the packages needs it.
I've selected all packages build-requiring perl-devel but don't
build-requiring python-devel directly - 520 in total. And from that number:
7 faild to build for unrelated reasons
3 packages have python3-devel in buildroot (different reasons than
systempat-sdt-devel)
81 packages have python3-libs but not python3-devel (different reasons
than systempat-sdt-devel)
and finally, the rest - 436 packages - builds fine without the python
script in systemtap-sdt-devel and therefore without Python at all.
My idea is to split systemtap-sdt-devel into two packages: one with all
the content but without the python script (/usr/bin/dtrace) and a new
one containing only the mentioned script.
That would make buildroots for many packages smaller and their builds
faster.
I also did a test rebuild of all packages directly build-requiring
systemtap-sdt-devel and identified these packages that really need the
dtrace script: glib2, sssd, qemu, python2.7, postgresql15, postgresql16,
perl, php, mariadb10.11, and libvirt. Those would newly depend on a new
package where we move the script to.
What do you think about this idea? Is it worth writing a Fedora change
for it?
Have a nice day.
Lumír
