[gentoo-dev] [PATCH] profiles: Reorder AMD64 profile list to place 17.1 on top

[gentoo-dev] [PATCH] profiles: Reorder AMD64 profile list to place 17.1 on top

[Brian Evans]

Users frequently are choosing the wrong profile versions in new installs
and accidentally downgrading to 17.0 with some saying they see it first.

A simple reordering could help new installs.

Since we do not guarantee ordering, any automated tooling concerns should not
be an issue because the full profile name can always be used.

Independent of this useful change, it's probably time to deprecate the amd64 
17.0 profiles!

Meh. Time to change that then...

Re: [gentoo-dev] Deprecating AMD64 17.0 profiles?

[Jaco Kroon]

Hi,

Having just completed the migration on two systems I found some things
which concerns me:

1.  A default/linux/amd64/17.0/desktop to
default/linux/amd64/17.1/desktop.  This differs from the no-multilib in
that there are symlinks now for the various lib32 to lib.  No such
symlinks on the no-mulilib systems (this makes sense, but why is lib32 a
symlink back to lib/)

2.  If /usr/local/lib* doesn't exist the script bails out.  This only
happened on one of the two systems I did now, specifically the
default/linux/amd64/17.0/no-multilib =>
default/linux/amd64/17.1/no-multilib one.  Other systems I've just
checked seems to already have this by virtue of
/usr/local/lib{64,32}/.keep existing, but no owners of the files, so
this could be sheer dump luck.  Which is never good.  Sorted by manually
creating lib32 and creating the symlink as instructed.  Post migrate
there is a lib/ and lib64/ folder.  The complaint on this was about
/usr/local/lib32 if I recall correctly

What is the actual "target" objective with the change?  I would have
expected (not being one to follow this too closely):

lib/ - arch independent stuff (eg, netifrc / dhclient etc scripts).
lib32/ - 32-bit specific stuff (libs for 32-bit).
lib64/ - 64-bit specific stuff (libs for 64-bit).

What am I missing?

Kind Regards,
Jaco

Thank you, that makes a lot of sense and answers all my questions
...just wondering where the lib32 => lib symlink comes from now.

So if anybody else ends up wondering:

jkroon@plastiekpoot ~ $ ls -lah /lib32 /usr/lib32 /usr/local/lib32
ls: cannot access '/usr/local/lib32': No such file or directory
lrwxrwxrwx 1 root root 3 Nov  9 10:02 /lib32 -> lib
lrwxrwxrwx 1 root root 3 Nov  9 10:02 /usr/lib32 -> lib

equery has some answers that there are still stuff installed into
/usr/lib32 (which will likely clear over time, and the symlink will be
unmerged).  There is this one potential pitfall down the line that I'm
seeing, fairly certain this would have been covered and that a remerge
of glibc will fix this:

jkroon@plastiekpoot ~ $ equery belongs /lib32 /usr/lib32
...
sys-libs/glibc-2.32-r2 (/lib -> lib64)

So job well done to the implementation team!!  Great work thank you!

Kind Regards,
Jaco

As a matter of fact the complete migration procedure (including cleaning 
up lib32 symlinks) was described in the news items introducing 17.1, for 
instance "2019-06-05-amd64-17-1-profiles-are-now-stable". In short, run

emerge -1v --deep /lib32 /usr/lib32 /usr/lib/llvm/*/lib32

and the lib32 symlinks should go.

I for one am not so excited about the amd64 17.1 profiles. On the surface
it appeared to me that one developer has "taken over" just about everything,
which (regardless of the individual) can't be a good thing..

baselayout contains a conversion to/from lib symlink(s).

Hi Fabian
I tried to migrate my prefix to 17.1, and there are issues.

1) unsymlink-lib requires "--root ~/gentoo" and otherwise produces an
error "/usr/lib is a real directory! was the migration done already?"

2) $ unsymlink-lib --root ~/gentoo --migrate --pretend
usage: unsymlink-lib [-h] [-p] [--root ROOT] [--analyze] [--migrate]
                     [--rollback] [--finish] [--force-rollback]
                     [--resume-finish] [-P PREFIX] [--hardlink]
unsymlink-lib: error: Requested action requires root privileges

Well, I worked it around by adding "is_root = True" to unsymlink-lib

3) Step 9 (Rebuild gcc) fails:
configure:4372: checking whether the C compiler works



configure:4394: x86_64-pc-linux-gnu-gcc    conftest.c  >&5

I think unsymlink-lib doesn't have Prefix support, but in addition,
what unsymlink-lib is trying to achieve, is not a thing perhaps on
Prefix.

A prefix system (at least all of mine) doesn't have libXX or lib/XX
(a.k.a.  multilib) directories.  The /usr-split was long ago removed,
and thus what we have is:

  lib -> usr/lib

Now, SYMLINK_LIB=no seems to split into lib and lib64, but lib64 does
not exist on Prefix systems.

Since Prefix is non-multilib by design*, I wonder if unsymlink-lib is
necessary in the best case, but going to break the Prefix system in the
worst case.

What instructed you to perform the migration?  Was it the news-item?  I
don't think it should apply for Prefix profiles, and perhaps we should
be happy the tool won't work.

* non-multilib is a decision dating back a decade or so, which means
  effectively any Prefix install you encounter should be non-multilib

Did it do anything to your system like creating a lib64 directory?  Does
anything work (because I have doubts on whether your system can still
find the libs in there now).

Something like this I was suspecting.  Can you still rollback?  If you
can, I'd try that and hope it restores your system in working order.

For any Prefix user, DO NOT run unsymlink-lib, I believe you should NOT
NEED IT!

So what you're saying is that you've had the wrong value of SYMLINK_LIB
for ages, and now you've created a meaningless 17.1 profile that chnages
it but isn't actually supposed to change anything, correct?

I guess, because the amd64 17.0 profile is deprecated with force, and I
had to do something ...

Now that's a lie.  Only the regular amd64 profiles are deprecated.
There are no deprecation notices e.g. in the x32 profile or prefix
profiles.

Our profiles either directly depend on the amd64/17.0 profile, or we use
a sub-profile from amd64/17.0 profile, so if it's going to get removed,
we are having a problem, don't we?

It isn't going to be removed as long as other profiles depend on it.
 It'll probably be re-parented.

It was the big scary warning about the deprecation whenever I run
emerge. It contains list of steps.

Yeah, don't worry, this is my ebuild-testing chroot. I just did "lxc

Warning: no lib32 paths found. This is fine if you are running no-multilib,
otherwise this is suspicious.


The state has been saved and the migration is ready to proceed.
To initiate it, please run:

Please do not perform any changes to the system at this point.
If you performed any changes, please rerun the analysis.

Initial migration complete. Please now test whether your system works
correctly. It might be a good idea to try rebooting it. Once tested,
complete the migration and clean up backup files via calling:

	/home/user/gentoo/usr/lib/python-exec/python3.7/unsymlink-lib --finish

If you wish to revert the changes, run:

	/home/user/gentoo/usr/lib/python-exec/python3.7/unsymlink-lib --rollback

Ok.  I don't know if we can do anything about that.

The logs seem to indicate that it thinks all libs on your systems do not
belong to any package.  This suggests the tool cannot locate the VDB or
something, as most of the things in the list are obviously owned by
packages.
