This looks like a reworking of Brian's "Fix broken seed stage
update..." [1].  It would probably be a good idea to explain the
differences between the two patches, since they seem to be solving the
same issues in slightly different ways.

Cheers,
Trevor

I'm already having issues with preserve-libs even when I force disable
it in the env scripts.  I would really prefer this is to be made
optional before inclusion.  Even an esoteric/arcane option would make me
happy here.

Re: [gentoo-catalyst] [PATCH 1/2] Fix update_seed use by not using nor building binary packages during the seed update.

It has come to light that this patch breaks binpkg use in stage1.
Personally I'd like to revert it entirely as the code is complex and
confusing to me for no reason.  Seperately I would fix the default
update_seed command because the "--rebuild-if-new-ver gcc" bit seems a
lot better to me.

Everyone approved this patch and it's been sitting in git for 2 months
without anyone realizing it's broken.  That alone should make it evident
that this code is too hard to read.

Can I get an ACK or NACK from the team members?

Thanks,
Zero

As it turns out, this one change was incorrect to evaluate all possible
scenarios.  My bash skills are poor, I originally had used nested if's ,
but that got optimized by others to the above line.

That line should be changed to:

elif [ -n "${clst_PKGCACHE}" ] && ( [ -z "${clst_update_seed}" ] || [ "${clst_update_seed}" == "no" ]

Which breaks down to (for those that can't follow it's logic):

# NOTE: clst_update_seed is currently only used for a stage1, so does not exist in the environment for other targets.
# spacing was added to the line so it lines up with the plain English text.

# if clst_PKGCACHE is not null   and  either clst_update_seed doesn't exist  or clst_update_seed is exactly equal to "no"
#if [ -n "${clst_PKGCACHE}" ]    &&  (        [ -z "${clst_update_seed}" ]   ||   [ "${clst_update_seed}" == "no" ] )


I have 3 reasons for wanting this change done this way

     1.  If a spec or config enables the PKGCACHE option.  It will add
        all the binpkg options to the emerge command.  Due to the
        possible problem with using/creating binpkgs during the
        update_seed process. These options should not be set.  Currently
        they are being set, but only --binpkg was being reset to =n in
        the stage1-chroot.sh update_seed command.  The other binpkg
        options were not being removed or reset.  This is poor coding.
        It is far better to just not add the unwanted options in the
        first place.
     2. While it is possible to work around not having the logic in
        setup_myemergeoptions(), it is hacky and complicates the
        stage1-chroot code more than neccessary.  It is also poor
        programming style.  In total it would mean the
        setup_myemergeoptions() would be called three times in total for
        the stage1 run.  Or temporarily saving the emerge options,
        unsetting clst_PKGCACHE, re-running setup_myemergeoptions() to
        get the correct options for update_seed, then later restoring
        the the two variables correctly. Both these coding options are
        poor programming style and more prone to bugs.  With the
        proposed change above it would be run twice.  Once keeping the
        PKGCACHE options off for the update_seed run, then reset
        according to the spec for the target emerge run.
     3. Placing the clst_update_seed logic to toggle the PKGCACHE
        options in the setup_myemergeoptions() simplifies the stage1
        code.  Plus it leaves the option to run an update_seed
        option/command for any future or current target without
        complicating/duplicating code.

I have attached a small test program I used to come up with the
correctly working patch change above.  It can be used to evaluate how
the line's logic is processed.  I have also attached the terminal output
it produced for all the possible conditions that could occur.  

Also I have slightly different PKGCACHE options in my rewrite branch.  I
have added --binpkg-respect-use to them.  It was brought to my attention
early in testing to put them in a config to eliminate the problem of
using binpkgs that were not compiled with them set correctly.

I will be pushing an updated rewrite branch with this and the other
changes made to master soon. So "git pull --force" to update your
checkout with the rewritten commits when I do.

Can you please describe how using binpkgs during update_seed is an
issue?  I don't think all of us fully understand that, I know I don't.

We should probably make this default, if everyone agrees I can drum up a
quick patch and add it.  This is already default in my profile to
infinite success.

This was all discussed in irc and the catalyst list.  But somehow you
seemed to miss it all.

Early this year, mpc had an updated version.  
The existing update_seed command:

  clst_root_path=/ run_merge "--buildpkg=n --update --deep --newuse
--onlydeps gcc"

updated mpc, consequently, libmps.so,2 was deleted. libmpc.so.3 was
created.  This broke the existing gcc pkg due to the missing lib.
This means that gcc needs to be rebuilt in order to be linked to
libmpc.so.3. The existing command excluded gcc from being built (the
opposite to what is needed).  This failure in gcc did not show up until
stage2 I believe, and was a bit troublesome to pin down the cause. 

 Which is why I changed that line to:

clst_root_path=/ run_merge "--update --deep --newuse --complete-graph
--rebuild-if-new-ver gcc"

It may be slightly overkill with the --deep --complete-gragh but it
removes potential problems in revdep-rebuild, so...

NOW for how binpkgs play into this.

Existing gcc binpkgs have been linked to libmpc.so.2 and portage does
not check that all lib links exist before qualifying the binpkg to be
installed.  Therefore installing a gcc binpkg is a hit and miss
proposition.  Making it's use un-reliable.  Therefore until the
toolchain is migrated to eapi 5 with proper subslot use.  Using binpkgs
is unreliable for update_seed.

While this may slow down the stage1 process some.  It does make it more
reliable, so that the releng team won't be wasting time tracking down
errors that can be otherwise prevented.  Binpkgs can be created and
reused with some caution for the regular stage build.  But some errors
may similarly occur if the snapshot used is changed between runs without
clearing or checking existing binpkgs.  Again eapi 5 pkg migration will
solve this.  Hence the user beware warning.

It was you that told me about that option, which is why i added it as
default when PKGCACHE is enabled.
That is something that Jorge did not pick up in my proposed patch.  I do
not know why.  Nothing was said as I recall.

In fact, the command is "--rebuild-if-new-ver" not
"--reinstall-if-new-ver".  As such, the original reporter of this bug
and I both seem to think that even with --usepkg, gcc should be rebuilt:

https://bugs.gentoo.org/show_bug.cgi?id=461422

That's obviously not how it is, but I feel we should focus our attention
on fixing this properly.

As a rule, we don't want to hack around limitations in portage to make
catalyst work.  The toolchain team seems to have made it very clear they
aren't updating to eapi5 soon, but the portage team has been fixing
things left and right based on little more than my whims, I'd give them
a chance to fix this before throwing hacks into catalyst to work around
limitations in the package manager.

I think you did a typo there.  There are 2 portage options
--rebuild-if-new-ver and --rebuild-if-new-rev.  I opted for the *-ver
(version), since most revisions would not need to trigger a rebuild.
But the failure in that bug should be the same or similar fix to our
needs.

If someone wants to work on fixing it.  The solution will require
extracting the NEEDED.ELF.2 info from the binpkg and confirming that the
links exist.  If any of them don't, then trigger the build from source.
Rejecting the existing binpkg.

You may also want to talk to blueness, he created a utility for looking
for broken elf links.

Not sure how *I* did a typo, looks like I typed the command properly
above, and I've not even commented on the bug yet... Yeah I do realize
that the bug is talking about -rev not -ver but the affected code
appears to be shared hence why it's brought up.

Here is where I admit to being lazy, I was planning on "fixing" it by
just triggering the src build no matter what when a rebuild occurs and
then hoping that someday people in gentoo actually use EAPI5 and make
this all unnecessary.
