bug#63050: "guix pull" requires graphical libraries

[Andreas Enge]

While trying out a "guix pull" on an aarch64 machine, for which many
packages are currently not available as substitutes, I notice an extra-
ordinary amount of dependencies, see below (and since I interrupted and
restarted it, there are even more dependencies in reality; I remember
X11 libraries such as libxi and libxt). Many of them are related to
graphical environments, which should not happen for a command line
program. Chances are they are pulled in for building documentation
(not necessarily of Guix, but of packages that are needed for pulling);
but this is still undesirable and should be sorted out.

Actually there is a relatively high risk that on non-x86 machines
"guix pull" will fail due to one of the packages not building.
And then if the packages are fixed, they cannot be pulled...
(but substitutes would still work then).

This is apparently coming from Graphviz:

--8<---------------cut here---------------start------------->8---
$ guix graph --path guix libx11
guix@1.4.0-5.286cdf0
graphviz@2.49.0
libx11@1.7.3.1
$ guix graph --path guix libxt
guix@1.4.0-5.286cdf0
graphviz@2.49.0
libxaw@1.0.14
libxt@1.2.1
--8<---------------cut here---------------end--------------->8---

Surprising to me, but apparently it’s been this way from the start,
commit b1b07d72c755ea314fb0c8333cd88293ee504ce4 (2013!).

Maybe these are optional dependencies?

So "guix pull" builds what is defined as the guix package, but with the
current checkout as source?

The package definition of guix has this among the native inputs:
                       ;; XXX: Keep the development inputs here even though
                       ;; they're unnecessary, just so that 'guix environment
                       ;; guix' always contains them.
                       ("autoconf" ,autoconf)
                       ("automake" ,automake)
                       ("gettext" ,gettext-minimal)
                       ("texinfo" ,texinfo)
                       ("graphviz" ,graphviz)
                       ("help2man" ,help2man)
                       ("po4a" ,po4a)))

Maybe these could be dropped then, and we could have an expanded package
guix-devel that would add these inputs for "guix shell -D guix-devel"?

Or is it needed for "guix graph"?
$ guix graph --list-backends
  - graphviz: Generate graph in DOT format for use with Graphviz.
...

But for this we do not need any graphical output, it is just text file
creation; could we have a graphviz-minimal in console mode?

No, guix pull uses (guix self), and the dependencies there are not used
in a singular place like (inputs ...) or (native-inputs ...), but are
peppered throughout the file.  However, it uses a reduced dictionary for
specification->package to speed it up, and so gives a pretty good idea
of what's used:

No, guix graph uses its own graphviz implementation!  It is used to
generated png files from .dot files while building the documentation.

I don't really know if we can skip graphical libraries for this reason.

bug#63050: "guix pull" requires graphical libraries

Hi folks, just dropping by real quick

Having built glib from scratch more often than is fun, I am quite
certain that the package pulling in our graphics stack is texinfo with
its reference to texlive.

where do you see this?
$ guix gc --references `guix build texinfo`
/gnu/store/5j85qqflgx8nnzk86i43mxn0rjm8h2gv-perl-archive-zip-1.68
/gnu/store/930nwsiysdvy2x5zv1sf6v7ym75z8ayk-gcc-11.3.0-lib

So texinfo should be fine.

It is this explicit inclusion of graphviz that poses problems (glib is
then pulled in also).

This would check the store path's references, but not necessarily all of
its inputs!  I would hope that no package with docs ever keeps
references to texlive.

Indeed! But here these are also the (native) inputs.

It does turn out there's no `guix graph texinfo --path-to texlive'
either, though, so I was actually mistaken.

Why does Guix require ’graphviz’ in the first place?

It uses it to build images in the manual.

All the X libraries can be seen in the output of:

  ldd $(guix build graphviz |grep -v 'doc$')/lib/graphviz/libgvplugin_xlib.so

I haven’t checked but I suppose that’s used by ‘xdot’.

We can get an X11-free Graphviz like so:

The closure size reduction is substantial:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix size graphviz | tail -1
total: 183.6 MiB
$ guix size graphviz | tail -1
total: 242.3 MiB
--8<---------------cut here---------------end--------------->8---

But I suspect we’d still need the full-blown variant for things like
xdot.

Ah.  So we are dragging X11 libraries as libx11 for one or two figures
in the manual. :-)

Although that’s not exactly the same as “guix pull”,

    guix graph guix -t bag-emerged

gives an idea.  Well, for example, there is a path from guix to ninja
via graphviz.

While I understand that the documentation is important, could we skip it
for some architectures?

Cheers,

Yeah, we could have graphviz (with libx11) and graphviz-minimal (without
libx11) and make Guix depends on graphviz-minimal.  WDYT?

Or just move it to a separate output or package?  That should really be
something done for all packages automatically tbh.  Alpine gets this right.

Well, I do not think a separate output would be possible and we are not
talking about the package named ’guix’ but about what is implemented by
the module (guix self).

Somehow, I agree that one direction would to make optional some
features.  The current proposal for tackling this issue is the reduction
of the closure by removing lix11 and libxrender as discussed in [1].

It should be made possible IMHO.  It's nice that our packages come with
docs, including Guix, but they are often unnecessary.  If an output
won't work because guix-self is special, then maybe it could be moved to
a separate package.

Typo? The issue is not found.

Note that I do not care so much about the closure size, but about the
number of packages that are needed to just build guix (although of course
the two are related). Or otherwise said, the dependencies for "guix pull".
On "exotic" architectures, each dependency is a potential cause of failure,
and all in all it may take hours (days?) to run "guix pull" without
substitutes, with a high chance of failure.

Typo on your side then?  :-)

Yes, understood.  Graphviz is not in the closure anyway, it’s a
build-only dependency.

With commit 9fa92acbf0c4dbc734ac7d83b31bd6d12e09a401 this is mostly
fixed.  There’s still another path leading to libx11 though:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix graph --path guix libx11
guix@1.4.0-6.dc5430c
guile-avahi@0.4.1
avahi@0.8
dbus@1.14.0
libx11@1.8.1
--8<---------------cut here---------------end--------------->8---

(The same applies to “guix pull”.)

Not sure what can be done about it.

How many bytes do we add (closure of guix) when adding one new package?

[Simon Tournier]

Hi,

The initial discussion was about the closure of Guix and that “guix pull”
brings graphical libraries.  See #63050 [1].

Here, I would like to open a discussion about how Guix scales,
i.e. about its size.  I am trying to answer the question I am asking as
the subject. ;-)

It’s another angle to view Andreas and Ludo discussion: :-)

>> Note that I do not care so much about the closure size, but about the
>> number of packages that are needed to just build guix (although of course
>> the two are related). Or otherwise said, the dependencies for "guix pull".

Somehow, the closure is increasing:

--8<---------------cut here---------------start------------->8---
$ for i in $(seq 1 4); do guix time-machine --commit=v1.$i.0 -- size guix | grep 'total:' ;done
total: 410.9 MiB
total: 496.0 MiB
total: 564.8 MiB
total: 637.2 MiB

$ guix size guix | grep 'total:'
total: 611.2 MiB
--8<---------------cut here---------------end--------------->8---

(Yeah, the package guix is not exactly the same as guix itself, but it
appears to me a good enough approximation.  And my current revision is
14c0380.)

Compare:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=v1.1.0 -- size guix --sort=self | wc -l
44

$ guix time-machine --commit=v1.4.0 -- size guix --sort=self | wc -l
72

$ guix size guix --sort=self | wc -l
70
--8<---------------cut here---------------end--------------->8---

which is the Andreas’s concern for “exotic” architectures.  Moreover,
the inflation (in size) is about some packages that are just becoming
bigger.

Considering Guix itself, one explanation for the increase is the number
of packages – assuming the services and other are negligible; “git diff
--shortstat” is a good indicator at first sight.  Well, we could be more
precise about the documentation.  Hum, this ugly,

--8<---------------cut here---------------start------------->8---
$ for doc in $(for ci in $(for t in $(git tag | grep v1 | grep -v rc ); do git --no-pager show $t | grep commit ;done); do for d in $(find ~/.cache/guix/inferiors/ -type l -print); do printf "$d "; $d/bin/guix --version 2>/dev/null ;done | grep $ci ;done | cut -f1 -d' '); do du -sh $(readlink -f $doc)/share/* ;done | grep info
172K	/gnu/store/5pa1706ckwhn6x4mn5kl2b7h15k3in9x-profile/share/info

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

is probably providing a clue about the assumption.

Ok, let assume that the packages are the main source of size increasing.

The question is: can we evaluate the size for one package?  How many
bytes do we add to the whole Guix when we add one package?  On average
and roughly.

We have the number of packages and the whole size for successive
versions.  Therefore, we can do the difference between the two.  We get
[2078, 1848, 4704, 1532] which means 2078 packages had been added
between v1.1.0 and v1.2.0, 1848 between v1.2.0 and v1.3.0, etc.

We can do the same for the size, [22.9, 19.4, 66.2, 20.1] and then we
can compute the ratio: the size per package.  Something like:

[0.011020211742059676, 0.010497835497835485, 0.01407312925170069, 0.013120104438642276]

Let get an average: 0.012177820232559531.

Now, let take the number of packages for v1.1.0 and do the
multiplication.  We get: 159.6 MiB.

Ok, it means that the difference is more or less the core of Guix – what
we are assuming that is slowly growing.  It reads 62 MiB.

Therefore, we can predict the size for the other versions using this
linear model based on the previous evaluated average.

    size = mean * number_packages + core

It reads:

[246.9, 269.4, 326.7, 345.3] compared to [244.5, 263.9, 330.1, 350.2].

Hum, this quick back-to-the-envelope computation does not seem too bad.
I guess.

Conclusions:

 1. the addition of one package leads to an increase of ~ 12 KiB

 2. the core of Guix is about ~ 62 MiB

 3. doubling the number of packages is doubling the size to download at
    “guix pull” time.


Maybe, we should re-think (guix self).  Especially the *package-modules*
part and re-discuss if we could split that part.  From my understanding.


Cheers,
simon

I agree that .go files are quite big (.scm files as well, but we’ve
improved information density somewhat by removing input labels :-)).

The size of .go files went down when we switch to the baseline compiler
(aka. -O1):

  https://lists.gnu.org/archive/html/guix-devel/2020-06/msg00071.html

That thread has ideas of things to do to further reduce .go size.

Download size has to be treated separately though.  For example, ‘git
pull’ doesn’t redownload all of the repo or directory, and it uses
compression heavily.  Thus, a few hundred bytes of additional .scm text
translate in less than that.

As for the rest, download size can be reduced for example by choosing a
content-address transport, like something based on ERIS.

I think we must look precisely at what we want to optimize—on-disk size,
or bandwidth requirement, in particular—and look at the whole solution
space.

My 2¢!

Just to put a figure on what means “big”: currently the .go files are 5
times bigger than their associated .scm.

Somehow, it’s the trap of DSL. :-) Packages are declarative and the
information they declare is not dense.  However, because they are
bytecompiled to a general programming language, their specificity is not
exploited.  In an ideal world, the compiled binary representation of the
packages should be smaller than their human-readable text-file
counterpart.

The mentioned improvement is nice.  And it’s visible:

However, it has almost no impact on the whole size; scaled by the number
of packages.

I think one direction is to tackle the way *package-modules* is built.
Because of that, Guix is building too much and the design is not optimal
– whatever technical solutions we implement for improving after that.

On my poor laptop, Guix is becoming unusable because many operations are
becoming so slow – when it’s still acceptable with APT of Debian.  For
instance, it’s something like 20 minutes for running “guix pull” without
substitutes.  And when I am traveling without a fast Internet
connection, it’s often too much for the network at hand.

Currently, “guix pull” is either building too much and downloading too
much; by design.

Something I've been considering is if Guix could make use of database
optimizations on its packages.  Having access to Scheme for everything
is nice, but using it as a storage solution is kind of silly when we are
mostly just storing structs.  Some kind of struct-of-arrays optimization
could definitely reduce their size by a lot, might even speed up some
operations.  It makes zero sense to load full package definitions from
disk for most queries, such as guix search, with an SoA representation
we could load only the fields that we care about.

ps.: Now I'm even more glad that I'm using a file system with
transparent compression on all my Guix systems.

This is probably a tagent, sorry, but I was curious how well the .go files 
compressed. It seems quite well, actually:

jackhill@mimolette ~/.config/guix/current/lib/guile/3.0/site-ccache/gnu [env]$ sudo compsize .
Processed 595 files, 1659 regular extents (1659 refs), 0 inline.
Type       Perc     Disk Usage   Uncompressed Referenced
TOTAL       21%       36M         173M         173M
none       100%       16K          16K          16K
zstd        21%       36M         173M         173M

That’s already the case; see
~/.config/guix/current/lib/guix/package.cache.

For instance, “guix package -A” exploits it and the performances are
acceptable.  Two past summers, wow already! I tried to augment it and
exploit it for “guix search”.  The implementation and benchmark is in
#39258 [1].  Well, the whole thread of #39258 appears to me worth to
consider because it spots various bottleneck specific to “guix search”
and explains why the improvement is not straightforward.

Well, I have started months ago to write a Guix extension using
guile-xapian.  My aim is to tackle two annoyances: 1. the speed and
2. the relevance.

About the relevance #2, the issue is that the current scoring considers
only the local information of one package without considering the global
information of all the others.  Well, see [2,3,4] for some details. :-)

Did you benchmarked the performances for some Guix operations on these
compressed vs uncompressed file system?

Cool!  Could you do (or anyone else with btrfs),

    guix time-machine --commit=d62c9b2671be55ae0305bebfda17b595f33797f2 \
         -- describe
    guix time-machine --commit=a099685659b4bfa6b3218f84953cbb7ff9e88063 \
         -- describe

then report the size (compsize) of

/gnu/store/nqrb3g4l59wd74w8mr9v0b992bj2sd1w-guix-d62c9b267-modules/lib/guile/3.0/site-ccache/gnu
/gnu/store/s6rqlhqr750k44ynkqqj5mwjj2cs2yln-guix-a09968565-modules/lib/guile/3.0/site-ccache/gnu

?

That's a good improvement, but it's in addition to the ELF files, so it
doesn't save any space, and as far as I know it doesn't speed up
non-textual queries, like searching for packages that use a specific
build system.

Thanks for the links, gonna read them in more detail later.

I haven't, but I have recently tried to move to a larger drive and
accidentally did a btrfs send without compression and the system didn't
fit.

i'd like to quickly point out something while we are discussing this:

when i came to guix it was rather confusing that there two namespaces through which one can get hold of a package object:

1) module-global variables in the scheme module system

2) a reified repository of packages (i.e. a scheme hash table, and some lookup functions).

these two namespaces are quite indepenedent from each other, and there are no formal rules that govern the relationship between the two.

there are scheme variable reference in some places, some others issue a call to SPECIFICATION->PACKAGE, manifests do that implicitly (?), etc. my gut feeling is that there is potential here for unification and simplification, without limiting composability.

Hi,

With a BTRFS filesystem compressed with zstd:3, I get:
