[gentoo-dev] Portage prelink patch?

[gentoo-dev] Portage prelink patch?

Gentoo Developers and Users,

I haven't been able to find any pre-existing prelink functionality built into 
Portage's build system, although I've heard it was present previously and was 
removed. Are there any plans to re-implement that feature?

grep prelink /usr/lib/portage/pym/portage.py
gives lots of crap ...

So it is still there! In fact there is a trivial patch waiting to be
merged for prelink. So portage is prelink enabled, it just does not run
the prelink command automatically .

This was because prelink was slightly buggy and could not be relied on
the succeed and took too long to run.

Newer versions of prelink are much better so there could be a new case
to make portage run prelink after a (un)merge automatically.

But I cannot be bothered to push the idea (laziness).

Since it is a trivial patch I hope you can get it in for portage-2.0.51.

Is this http://bugs.gentoo.org/show_bug.cgi?id=63563 or is there another patch 
which automatically prelinks new installed binaries/libraries?

That is the pending trivial patch. 

Making portage automatically prelink binaries and libraries in my
opinion is non trivial, as there is a large impact in portage
performance and things can go wrong easily.

It is doable if anyone wants to develop it, just not me.

I think FEATURES="prelink" might do it...

Nope, that was not implemented. In the end portage just checks for the
existence of the prelink binary. If it exists then it uses that to
calculate the MD5sum verification of files. ( as prelinked files have
different MD5sums then the originals )

( read portage.py )

Also the file /etc/prelink.conf is automatically generated by portage,
if prelink is installed.

That is all the prelink support in portage.
