[bug#70169] [PATCH 0/7] Reproducible `make dist' tarball in defiance of Autotools and Gettext

[Janneke Nieuwenhuizen]

Hi,

The recent XZ-utils <https://www.openwall.com/lists/oss-security/2024/03/29/4>
debacle inspired me to resurrect and finish my patch set for creating a
reproducible source tarball for Guix, i.e., finally have `make dist' be
reproducible (when run from Git).  I've been using a version of these patches
in simpler projects for some years now and stole one from Timothy Samplet's
Gash project.

Autotools and Gettext still make it harder than necessary to do reproducible
(responsible?) computing, which is especially sad given the fact that the
Reproducible Builds project recently had their 10th birthday
<https://reproducible-builds.org/_lfs/presentations/2023-05-27-R-B-the-first-10-years/#/>.

Gettext tooling embeds timestamps found in the file-system, fails to respect
SOURCE_DATE_EPOCH, and lacks options like `--pot-creation-date' so that we
have to resort to SED to fixup.  The caching of all sorts of information, in
separate build stages, also doesn't help.

To create a reproducible source tarball, having a reproducible build
environment is a prerequitite, so this would have to be recorded too.
Using this patch set, I created a tarball doing something like

--8<---------------cut here---------------start------------->8---
guix pull --commit=1dbe492b993a7629df3b35146ce0272b52913776
guix shell
bootstrap && ./configure --localstatedir=/var --sysconfdir=/etc && make dist
guix hash guix-1.3.0.57425-80a228.tar.gz
0mk59ay5k2dxmjni9fx4i8qyfhvlgxbhqzsjpg2pbw381nskkxbj
--8<---------------cut here---------------end--------------->8---

and I've uploaded it to

    https://lilypond.org/janneke/guix/guix-1.3.0.57425-80a228.tar.gz

Who can reproduce it...and WDYT?

(I've also pushed this patch set to `wip-tarball', as a slight difference
may already produce another tarball).

Greetings,
Janneke

Maybe we could drop ‘i’ and instead create ‘samp-fr’, ‘stamp-de’, and so
on?  That is, ‘version.texi-from-git’ would take 2 arguments instead of 3.

(That’s really a minor issue though.)

Nitpick: I'd use double quotes to avoid bad surprises:

  date="$$(git log …)"
  …
  mv "$@-t" "$@"

I don't think so, or, I wouldn't know how to do that.  The stamp-N is
created by Automake's magic.  They are distributed together with the
version-LANG.texi files.

If Automake would have used stamp-LANG, this would have been much
easier, we could probably have used stem (%) instead of this hairy
function.

> (That’s really a minor issue though.)

Ok, but if it's somehow possible, I agree it would be nice.

Yes, sadly that's expected, and couldn't figure out how to avoid this.
Any ideas would be greatly appreciated.  Automake will just create those
targets, and it seems we must override exactly those.  May Timothy has
an idea?

Looks like Automake can feel the defiance:

Sadness indeed.  Hopefully things will improve in the coming weeks, now
that there’s an impetus.

I applied the whole series on top of
df64d48e6f9f648044aa5279c045b8d6f7bee604 (the ‘base-commit’ at the
bottom of your message).  Thus I got the same content as you but with a
different commit ID.

“make dist” gave me guix-1.3.0.57425-9f4a4a.tar.gz.  The name indeed
corresponds to the tip of my tree:

--8<---------------cut here---------------start------------->8---

    maint: Ensure generated file reproducibility for dist.
    
    * doc/local.mk (override $(srcdir)/doc/stamp-vti): New target override.
    (doc-clean, man-clean): New targets.
    (auto-clean): Depend on it in new target.
    (DIST_CONFIGURE_FLAGS): New variable.
--8<---------------cut here---------------end--------------->8---

But as a result, I get a different hash, and since the directory in the
tarball has a different name, ‘diffoscope’ isn’t very helpful.

There’s at least one relevant difference in the gzip metadata:

(Your tarball has a CRC and comment, mine doesn’t.)

Maybe we’ll have to iterate once you’ve pushed a first version, so we
can truly build the same thing.  Or we should push the branch somewhere
(or use the one from <https://data.qa.guix.gnu.org/> once it’s been
created).

Thanks!

Yes, that would be nice.  With more people joining the effort, it could
be fixed brilliantly, in no time :)

Yeah..., that's why I pushed `wip-tarball'.  We even look at the
committer's timestamp (not author, as that could be quite old).

I believe this is a red herring.  I saw this all day whenever one file
had a difference...

I boldly pushed `origin/wip-tarball', you may try that :)

Be sure to git diff between your tip and origin/wip-tarball to ascertain
I didn't place easter eggs (just kidding).

I think AUTHORS and ChangeLog are amongst the simplest of our worries.
Setting TZ=UTC0 and LC_ALL=en_US.UTF-8 should address these.

That looks like a dependency or parallelism problem.  I made the
auto-clean dependency more strict and clean even more Autotools caching.

Yeah, there's also something with the (building of) the cookbooks.  I'm
hoping the strict auto-clean dependency fixes this too.

Hmm.  I've added a naive xgettext.scm wrapper to take care of this.

> Note that in ‘guix shell -CP’ I had no TZ and LC_* variable set and

Okay, thanks for the hint.  "Of course", you'll have to use something
like

    guix shell -CP -m manifest.scm fontconfig font-ghostscript \
        graphviz imagemagick texlive-bin

to make it succeed now.  When running in a container from a worktree
you'll also have to expose the master .git directory.

I fixed some image generation rules that would silently fail without
graphviz or imagemagic, or when fonts cannot be found.

Thanks, find a V2 soon.

[bug#70169] [PATCH v2 00/12] Reproducible `make dist' tarball in defiance of Autotools and Gettext

[Janneke Nieuwenhuizen]

Thanks for your support and to all who helped testing!

V2 brings

  * Use `override' with GZIP_ENV and am__tar to avoid warnings,
  * Add --best to GZIP_ENV (i.e., keep using --best),
  * Generate AUTHORS and ChangeLog reproducibly by setting TZ and LC_ALL,
  * Use double quotes for file-name variables in amended pot rules,
  * Generate POT files reproducibly using a new, naive xgettext.scm script,
  * Remove %%CreationDate from generated EPS files,
  * Reset CreationDate in generated PDF files,
  * Fix dist -> auto-clean -> doc-pot-update dependency,
  * Remove more Autotools caches (.am*, m4/, po/),
  * Document the expected override warnings for stamp-vti, stamp-N, and
  * A toplevel assert that Autotools cache is up-to-date with Git HEAD.

I have reset wip-tarball and uploaded
<https://lilypond.org/janneke/guix/guix-1.3.0.57430-933766.tar.gz>.

[bug#70169] [PATCH v2 13/12] doc: Use "dejavu sans" instead of "Helvetica" or "sans" in dot images.

Headsup: using the attached bonus patch the tarball reproduces for me
also without using a container, i.e., building it in

    guix shell -CP -m manifest.scm fontconfig graphviz imagemagick texlive-bin

or

    guix shell -m manifest.scm fontconfig graphviz imagemagick texlive-bin

now creates the same tarball for me.

Greetings,
Janneke

Subject: [PATCH v2 13/12] doc: Use "dejavu sans" instead of "Helvetica" or
 "sans" in dot images.

Font-dejavu is (now) an input of fontconfig.  Specifying "dejavu sans" makes
generated images reproducible even when other fonts are installed (notably
font-google-noto).

* doc/images/bootstrap-graph.dot,
doc/images/bootstrap-packages.dot,
doc/images/coreutils-bag-graph.dot,
doc/images/coreutils-graph.dot,
doc/images/gcc-core-mesboot0-graph.dot,
doc/images/service-graph.dot,
doc/images/shepherd-graph.dot: Use fontname = "dejavu sans".
* doc/guix.texi (Full-Source Bootstrap): Update gcc-core-mesboot0.dot recipe
accordingly.

Do I interpret correctly that “echo 0” is a fallback timestamp?

Looking at the now gone instructions from “git show
83c60bb0622440afe98930820186ddfa1e6e8b2f”, at that time, a timestamp of
1 was used for the tarball; I do not remember why.  In
guix/scripts/pack.scm, 1 is used for squashfs and docker images.

Is 1 a better timestamp than 0?

Regards,
Florian

Yes.

That's probably because of build dependencies.

> Is 1 a better timestamp than 0?

For files, using 1 is preferrable if it's not a source file.  We use 1
for .go files, and 0 for .scm files, iirc.  SOURCE_DATE_EPOCH is (only)
used for the date in the document.  Without git, 0 is as good a guess
for a reproducible date for use in a document as any, I think.

Greetings,
Janneke

Thank you for explaining.  So this SOURCE_DATE_EPOCH applies to all the
generated files in doc/ but still 0 is fine, because noone warns if they
are not later than source files, IIUC.

I see a non-fatal message here that

Perhaps AM_V_DOT cannot be used after export TZ=UTC0;?

Ah, that's not good.  Apparently I ontly tested using V=2 in the end.

I believe this should fix it

Come to think of it, as we're removeing CreationDate anyway, setting TZ
is quite unnecessary, and we can just do

.dot.pdf:
	$(AM_V_DOT)$(DOT) -Tpdf $(DOT_OPTIONS) < "$<" > "$(srcdir)/$@.tmp"
[..]

Thanks for looking into this!

In the store, a timestamp of 1 (not 0) is used.  This is because there
are tools (among which ‘make’ IIRC) that behave differently when mtime
is zero.

For consistency and to be on the safe side, it’s probably a good idea to
do the same (as the fallback in this case).

Oh, I see.  I didn't know there were internal uses of ‘stamp-N’.

Apparently ‘dot’ (GraphViz) does not emit a ‘CreationDate’ header.

Should we drop this change and add a line like this above the ‘mv’ line:

  @if grep -q CreationDate "$@.tmp"; then false; else true; fi

to be on the safe side?

>  .png.eps:

Looking into the code of ImageMagick, I see:

--8<---------------cut here---------------start------------->8---
        timer=GetMagickTime();
        (void) FormatMagickTime(timer,MaxTextExtent,date);
        (void) FormatLocaleString(buffer,MaxTextExtent,
          "%%%%CreationDate: %s\n",date);
--8<---------------cut here---------------end--------------->8---

where ‘GetMagickTime’ honors ‘SOURCE_DATE_EPOCH’.  Should we set
‘SOURCE_DATE_EPOCH’ and avoid the ‘grep’ trick?

OTOH, an argument to keep this patch as-is is that it’ll resist to
changes in ImageMagick/GraphViz.  So maybe the comments above aren’t
that relevant.

Let's do that, I'm adding it as

    $(AM_V_at)! grep -q %%CreationDate "$(srcdir)/$@.tmp"

[bug#70169] [PATCH v3 00/13] Reproducible `make dist' tarball in defiance of Autotools and Gettext

[Janneke Nieuwenhuizen]

V3 brings

  * Use `1' as fallback for SOURCE_DATE_EPOCH,
  * Do not remove %%CreationDate when creating EPS files.  Imagemagick's
    convert respects SOURCE_DATE_EPOCH (as long as it's not set to `0'!), and
  * Graphviz' dot does currently not insert it; add a check for that,
  * Update advice when Autotools's version is out of date to say
    ./bootstrap && ./configure ..., and
  * Use "dejavu sans" in DOT sources (already sent as v2 13/12).

I have reset wip-tarball and uploaded
<https://lilypond.org/janneke/guix/guix-1.3.0.57741-0e3053.tar.gz>.

[bug#70169] [PATCH v3 01/13] doc: Use "dejavu sans" instead of "Helvetica" or "sans" in dot images.

[Janneke Nieuwenhuizen]

Font-dejavu is (now) an input of fontconfig.  Specifying "dejavu sans" makes
generated images reproducible even when other fonts are installed (notably

[bug#70169] [PATCH v3 10/13] maint: Avoid EPS generation to fail silently, ensure reproducibility.

[Janneke Nieuwenhuizen]

Currently, Graphviz' dot does not insert a %%CreationDate.  ImageMagick's
convert on PNG->EPS does insert a %%CreationDate but it respects
SOURCE_DATE_EPOCH.

* doc/local.mk (.png.eps): Split single shell command into separate recipe
lines, prefixed by $(AM_V_at).
(.dot.png): Likewise.  Check that generated EPS file has no %%CreationDate.

Hello Janneke.

Could you enclose the call to git in
“if test -e .git; then … fi” as well?

I’ve switched to wip-tarball, but the hash is different.
It is still quite similar.

I've changed it to

	if test -e .git; then				\
	    git clean -fdx -- '.am*' build-aux m4 po;	\
	else						\
	    rm -rf .am*;				\

	    $(MAKE) -C po/packages maintainer-clean;	\
	fi

Wow, that's amazing news, and thanks for testing!  (I could have said:
well, using de_DE is /asking/ for such differences ;)

I tested with

    export LANG=de_DE LANGUAGE=fr_FR LC_TIME=pt_BR

and found similar errors, and only those.  In this case LC_TIME
prevailed.  So I made this change

and checked against a clean/LC_ALL=C locale.

Not sure if I should send a V4 for this?  Let's see if there are more
comments.

Greetings,
Janneke

LGTM.  No v4 needed in my opinion.
