That is correct (With mescc-tools-seed adding steps and removing
binaries over time)

I do, in mescc-tools-seed; the script bootstrap.sh when run with the
option "sin" will build the mescc-tools-seed binaries using mescc-tools.
The .M1 files are always generated by cc_x86.s using the C source files.

I've been building them from the stage0 bootstrap tree (which as you can
see is rather trivial:
https://github.com/oriansj/talk-notes/blob/master/Current%20bootstrap%20map.dot
)

We have eliminated the forward dependency on Mes for the creation of the
mescc-tools-seed already

Already done in bash and kaem but not in guix yet (Should be trivial)

> WDYT?
I think we will end up having several versions of mescc-tools-seed; as
each architecture guix supports will end up needing a variant if we plan
on keeping them small. (I also have no idea how to make a multi-arch fat
elf binary)

I am also curious if there is any demand for the stripped versions of
mescc-tools-seed as those binaries are nearly half the size.

also, AMD64 does support i386 binaries without issue

I saw this script but it’s not entirely clear to me how to package the
whole thing.  We don’t have a “stage0” package for instance in Guix, do
we?

For now let’s focus on x86_64/i686.  :-)

IMO we should change the seeds as rarely as possible because they are
managed “out-of-band” and verifying them is difficult (you need to fetch
the right Guix commit, run “guix build bootstrap-tarballs”, and compare
the result—assuming this is all bit-reproducible.)

The one we’re using today in Guix date back to 2013.

Thanks,
Ludo’.

I had a look but it seems we need either binary seeds for stage0, or
binary seeds for mescc-tools and I'd rather build them within Guix; so
that's what I did now.

Okay, I am proposing the attached patches, also available on my 
core-updates-next at http://gitlab.com/janneke/guix

Still I hope these won't last for five more years ;-)

I think it's important that the new bootstrap-tarballs be
bit-reproducible, such that they can be independently verified by anyone
who wishes to do so.

In particular, *I* would like to independently verify them, on my own
laptops where I have avoided using binary substitutes for a long time,
and which I keep with me at all times.

My hope until now is that when we generated our existing bootstrap
binaries in 2013, Guix was too marginal a project to attract the
attention of hackers who might wish to compromise our bootstrap.  In
2018, as Guix has become more popular, we might well be considered a
worthy target of such efforts.

Well I hope these will last for at least a couple of years, or at least
this is what we should aim for.

Replacing bootstrap binaries is not anecdotal as I wrote because these
are “binary blobs” that need a special procedure to verify them; that
they are smaller blobs is of course a crucial improvement, but it
doesn’t change the fact that one may want to verify them.

Neat; I’m glad it was as simple as this.  :-)

As discussed yesterday on IRC, please also make sure make-bootstrap.scm
does not refer to (gnu packages bootstrap) at all since that would be
like running in circles.

As discussed just now on IRC, we probably also need #:system
"i686-linux" in the appropriate places such that “guix build
bootstrap-tarballs” gives the same result on i686 and on x86_64.

OK.

If you want, before pushing this patch, you can first push the one
above.  From there I (and possibly others!) will run “guix build
bootstrap-tarballs” and make sure we get the same result as you did.

I suppose this is not directly related to the other changes, but anyway,
LGTM.

Thanks for the quick reply!

Yes, we should aim for that while creating them.  I'm possibly a bit too
eager to replace the reduced binary seed bootstrap by a scheme only
bootstrap and reduce all of our seeds even further.

Fully agree.

Thank you.  Right, that's fixed now.

I'm looking into that right now.

Great, done.  I missed

    5b01b6034aeab32a5011c5757f18bd9772d3497d python: Honor '--cores=...' in tests.

happening yesterday; so pushed as

    bootstrap: Add mescc-tools-static, mescc-tools-static-tarball.

Note you'll also need something like these three extra commits

--8<---------------cut here---------------start------------->8---
2d8f7e2ac bootstrap: Update %bootstrap-tarballs.
57fbf077a bootstrap: Replace %mescc-tools-seed with %bootstrap-mescc-tools.
706574ee4 bootstrap: Add %bootstrap-mescc-tools.
--8<---------------cut here---------------end--------------->8---

from core-updates-next @ https://gitlab.com/janneke/guix to be able to
build `guix --system=i686-linux bootstrap-tarballs'.  Until then, the
recipe is

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix build --system=i686-linux mes-stripped-tarball mescc-tools-static-tarball
--8<---------------cut here---------------end--------------->8---

Rebuilding that right now, let's compare what we get.

Thanks for all your input!

Just to give you a heads up: left to build this last night to find that
the python patch does not build for me.  I reverted the python patch on
my personal branch and start a new build.

Not sure what to do about this, YMMV but this is what I get

Hello!

Meanwhile, I have updated core-updates-next to include

    d9ed0a463 bootstrap: Update %bootstrap-tarballs.
    4fd4efc81 bootstrap: Replace %mescc-tools-seed with %bootstrap-mescc-tools.
    562c37c7b bootstrap: Update %bootstrap-mes.
    b00a95be2 bootstrap: Add %bootstrap-mescc-tools.

With these, I can build

   ./pre-inst-env guix build hello
   ./pre-inst-env guix build --system=i686-linux hello
   ./pre-inst-env guix build --system=i686-linux bootstrap-tarballs

If these reproduce, we're getting real close.  However...

On my core-updates-next at gitlab I also have (see attached)

    5c2209ad4 bootstrap: Force i686-linux for bootstrap-tarballs.

which tries to support

   ./pre-inst-env guix build bootstrap-tarballs

which fails when attempting to build gcc-cross-sans-libc-i686-unknown-linux-gnu-5.5.0

    /tmp/guix-build-gcc-cross-sans-libc-i686-unknown-linux-gnu-5.5.0.drv-0/build/./gcc/cc1: error while loading shared libraries: libisl.so.15: cannot open shared object file: No such file or directory

I do not understand the dependency chain of why exactly this is being
rebuilt and what %current-system is, or why it fails.

Hello again!

The last problem left for me before we can verify the new bootstrap
tarballs and move them to ftp.gnu.org:guix was for

   ./pre-inst-env guix bootstrap-tarballs

to succeed.  We needed to force #:system "i686-linux" for
mescc-tools-static and mes-minimal.  This triggered a build of
gcc-cross-sans-libc-i686-unknown-linux-gnu, that did not succeed.

I found that the mes-minimal recipe used #:system "i686-linux" and on
x86_64-linux still depended on a i686-linux cross compiler.  With that
removed, I now have for you the tarballs as I produced them.

I have updated core-updates-next with this fix, a documentation update
and to also include Marius' mes bootstrap cleanups from his wip-gcc7
branch.

We may want to change the bootstrap downloads for x86_64 in
bootstrap.scm, mescc-tools-static and mes-minimal-stripped and
linux-libre-headers-stripped to use the x86_64-linux variants (currently
we use the i686-linux tarballs); but as you can see their content is
identical.

Happy verifying ;-)

Subject: [PATCH] bootstrap: Force i686-linux for bootstrap-tarballs.

* gnu/packages/make-bootstrap.scm (%mescc-tools-static): Force i686-linux for
bootstrap-tarballs.
(%mes-minimal): Likewise.  Remove i686-linux cross-compiler dependency.
* gnu/packages/commencement.scm (mes-boot): Support strict i686-linux build on
x86_64.

So, on x86_64-linux, here’s what I got:

--8<---------------cut here---------------end--------------->8---

So only ‘guile-static-stripped’ differs from yours.  This may be due to
non-determinism in bindings introduced by psyntax (something we
addressed with <https://bugs.gnu.org/20272>, but maybe there are
remnants around.)  I’ve uploaded mine here:

  <http://web.fdn.fr/~lcourtes/tmp/guile-static-stripped-2.2.4-x86_64-linux.tar.xz>

Could you share yours so we can compare?

Anyway, I’ll run the “-s i686-linux” build because right now I only have
the 64-bit ‘guile-static-stripped’, which is not what we want, silly me…
Should we force #:system for this one as well?

Thanks,
Ludo’.

Mine is here

    http://lilypond.org/janneke/mes/x86_64-linux/guile-static-stripped-2.2.4-x86_64-linux.tar.xz

...so it looks like we're walking a pretty big round , for --rounds=2 ;-)

Oh!  Eh, is that right?  I wasn't aware...

> Should we force #:system for this one as well?

We could but then should make sure that any go files in x86_64-linux
bootstrap binaries (mes, and in time gash) are i686-linux too.

Not sure if that's useful...hoping the specific names may ring a bell.

It clearly looks like the psyntax non-deterministic gensym bug described

I’ve just uploaded these to
<https://alpha.gnu.org/gnu/guix/bootstrap/i686-linux/20181020>:

  linux-libre-headers-stripped-4.14.67-i686-linux.tar.xz
  linux-libre-headers-stripped-4.14.67-i686-linux.tar.xz.sig
  mescc-tools-static-0.5.2-0.bb062b0-i686-linux.tar.xz

  mes-minimal-stripped-0.18-0.08f04f5-i686-linux.tar.xz.sig

Could you adjust bootstrap.scm to refer to this URL?  Currently I see
bootstrap.scm refers to a different version of
linux-libre-headers-stripped so it should be the only one whose hash
needs to be changed.

Thanks, and let me know if we need anything else!

I don't see that...and the hash matches.

See attached patch.  Push to my gitlab core-updates-next, not to
savannah yet.

We’ve discussed it in person, and now I think we’re all set!  :-)

Yes, that helped!  Pushed to core-updates as

Does our documentation include instructions on how to reproducibly build
these new bootstrap binaries, to independently verify them?

     Thanks,

The build procedure remains unchanged (info "(guix) Bootstrapping"):

  guix build bootstrap-tarballs

To verify them, you can do what I described in this thread, which is to
use the same commit as Janneke and myself used, run “guix build
bootstrap-tarballs”, and compare the three tarballs listed above.

Note however that while you're very welcome to do so now, Ricardo and
are working on at least a new mes-minimal-stripped-tarball that I
expect any day now.

What commit did you use?  It would be good to document this, so that
others can independently verify our bootstrap binaries, now or in the
future.

     Thanks,
       Mark

The commit appears in the commit log and in this very thread, no?

Yes, thanks.  I'm glad to see it in the commit log.  I thought it might
also be worthy of documentation in our source tree, possibly in HACKING,
for the sake of those who wish to independently verify our bootstrap
binaries in the future.  However, it's not something that I feel
strongly about.

     Thanks,
       Mark
