[gentoo-dev] 23.0 profiles - which features?

[gentoo-dev] 23.0 profiles - which features?

[Andreas K. Huettel]

[-- Attachment #1: Type: text/plain, Size: 2297 bytes --]

Hey all, 

in the past I already sent a mail about features for a next profile version.
The feedback was rather limited, but anyway we got quite a list of ideas.
The general tracker is bug 876891.

In the following I would like to put up the various features for discussion, 
in order of bug number... Feedback very welcome.

Cheers
Andreas


https://bugs.gentoo.org/515694
Bug 515694 - Update MIPS profiles to use ABI-specific CHOST values for 
clang/llvm compatibility
Affects only mips profiles. Should eventually be done, I guess?

https://bugs.gentoo.org/675050
Bug 675050 - [toolchain] Enable GCC's -fstack-clash-protection for all 
profiles in Gentoo by default

https://bugs.gentoo.org/792081
Bug 792081 - rename no-multilib to nomultilib, also in profile names
Apparently this simplifies things for some people, and a new profile
is a good chance to do the cosmetic change.

https://bugs.gentoo.org/818376
Bug 818376 - [toolchain] Adopt SHT_RELR/DT_RELR relative relocation format
*very* new feature...

https://bugs.gentoo.org/831045
Bug 831045 - profiles: remove USE=cli default and inline into ebuilds
Easy.

https://bugs.gentoo.org/849875
Bug 849875 - profiles: remove USE=dri default, clean up make.defaults
Also easy.

https://bugs.gentoo.org/876879
Bug 876879 - separate openrc and systemd features, not one overriding the
other
Right now all profiles inherit openrc-specific settings, and these are
then again negated and/or overridden in the systemd profiles. Sorting
this more cleanly would be nice.

https://bugs.gentoo.org/876881
Bug 876881 - make merged usr the default configuration
With the next profile version, the "default" setting (default/linux/XX.X/amd64) 
is a merged usr profile, while the old layout is still present as a 
split-usr feature. Not sure if this is worth the trouble.

https://bugs.gentoo.org/876883
Bug 876883 - [tracker] time64 migration
Needed.

https://bugs.gentoo.org/876893
Bug 876893 - [toolchain] Adopt -D_FORTIFY_SOURCE=3 for hardened by default

https://bugs.gentoo.org/876895
Bug 876895 - [toolchain] Adopt -D_GLIBCXX_ASSERTIONS for hardened by default

To me usrmerge alone would be sufficient to provide new release, but
adding more changes in is a good idea too.

I would like to switch ppc64le profiles to 128-bit IEEE long double ABI
23.0 seems like a good cause to finally tackle it.
This will need some toolchain magic, I will open a bug and block
profile-23.0 tracker.
Fedora finally switched recently
https://fedoraproject.org/wiki/Changes/PPC64LE_Float128_Transition

I tried the switch about a year ago and ran into some trouble with
projects that bundle gnulib.


I'll open a bug and block the tracker.
