Hello,

I've been having a first look at guix data service.

And looking at the guix lint page, I saw the "should
probably be native input" warnings, and gave it a
try on sudo, naively thinking it would benefit
something (maybe a container or vm image size).

Is there a way to see any benefit from these changes
(without building a vm or container image each time) ?

Are those changes useful to do on their own ?

For example this:

diff --git {a,b}/gnu/packages/admin.scm
index 2f661f5e81..457dc1e3dc 100644
--- a/gnu/packages/admin.scm

Well yes it may reduce the closure size of the package (run `guix size
sudo`) to get it.

It can also fix cross-compilation. Because when cross-compiling, if
groff needs to be run at build-time, it needs to be for the native
architecture and not the target one.

You can check it by running `guix build --target=aarch64-linux-gnu sudo`
for instance.

Thanks,

Mathieu

I'm not seeing any size difference, but groff is not in the output:

That fails on master (libpaper) whereas with the patch it works,
so I guess the patch is useful on that front.

The patch for sudo will be in the following emails.

Is there anything else to check / test ?

Here is a set of patches, for starting discussion...

I only build-tested them natively on/for x86_64 (and
cross built for aarch64 for the sudo one)

Well you can also check for deterministic compilation, and all the other
items listed here:
https://guix.gnu.org/manual/en/html_node/Submitting-Patches.html

Also be careful because there were quite a lot of cross-compilation
related patches pushed on core-updates. You may want to check that you
are not duplicating this work.

Anyway, most of the packages that should cross-compile fail to do so
because of inputs/native-inputs mix-up, so your patches are really
welcome :)

Thanks,

Mathieu

Thanks for handling that.

Stay tuned for the next batch.

Christopher, looks like your work on data.guix.gnu.org already triggered
something useful ! ;-)

And the view for comparing with previous run is just showing
me what I wanted to see, perfect !

Question: would this view show any `guix size` difference if any ?

Keep up the good work !

Vincent,

There's some deeper confusion here: why do you expect the size to 
change, at all?

Making ‘groff’ native was the right thing to do (and please, keep 
fixing bugs like this! :-) but it has nothing to do with making 
packages smaller.

Kind regards,

Because I've been told so...

Never will ?

I'm not expecting package size to shrink, but package closure
(is that the right word) size to sometimes shrink.

And if I've understood that may be visible for ISO, VM, container
image sizes.

Am I mistaken ?
Still learning...

Unless you are cross-compiling (i.e. guix build --target=foo),
native-inputs and inputs behave exactly the same; they are simply
concatenated.

Nice, I'm glad that you're enjoying using the Guix Data Service, and
finding it useful :)

> Question: would this view show any `guix size` difference if any ?

So, `guix size` as I understand it looks at the size of the store item +
the size of all store items referenced both directly and indirectly.

The `guix size` script can use your local store, as well the data in
narinfo files from substitute files to determine the size of store
items, and there references.

The Guix Data Service gathers up narinfo files from substitute servers,
so the database should contain the necessary data on sizes and
references to provide equivalent information to the `guix size` script.

I like the idea of showing size changes on the comparison page, but I
think a good first step to take towards this would be to show the "size"
for a single item in the store.

This [1] is the page for the store output for the sudo package, with
your changes. It already shows the size from the narinfo files provided
by bayfront and berlin (3633056 bytes).

1: http://data.guix.gnu.org/gnu/store/l320ig872ny66d1yi6v7n4zb93iz50dx-sudo-1.8.31p1

It would be nice to have a URL like [2] (which obviously doesn't exist
yet) which would show similar information to running the `guix size`
script [3].

2: http://data.guix.gnu.org/gnu/store/l320ig872ny66d1yi6v7n4zb93iz50dx-sudo-1.8.31p1/size
3: guix size /gnu/store/l320ig872ny66d1yi6v7n4zb93iz50dx-sudo-1.8.31p1

Would this be something I'd be able to convince and support you to do
Vincent? I'd be more than happy to help you to implement this.

Chris

OK, thanks for the clarification.

Christopher, I'm not a web guy, I may take a shot at it, when
my todo list gets emptyish, but don't hold your breath, that
may not happen in this life...

Following this will come the next batch of native-inputs.
Built on x86_64, tried to also target aarch64, but kind of
unconclusive (one stopped at perl, another at mit-krb5...)

I've searched core-updates to avoid duplicating work,
but only after having done it... Got lucky to have only
lost a few minutes on openldap...

The graphviz patch may not be for master as it may
force 2918 packages to be rebuilt. The other ones
should be OK.

Question: should I stay on guix-devel, should I add
guix-patches or should I move to guix-patches for
the following patche series ?

Vincent,

Thank you!

This list is for general Guix discussion.  Although that can 
sometimes include rough patches (heh), please send any future 
contributions to our patch tracker at guix-patches@gnu.org — after 
carefully reading the ‘Submitting Patches’ section of the Guix 
manual.

Vincent Legoll 写道:
> * gnu/packages/version-control.scm (cgit)[native-inputs]: New 
> field.

This is no new field.  Neither are those of mailutils, iwd, or 
graphviz!

Please rewrite all commit messages as either

  * gnu/packages/version-control.scm (cgit)[inputs]: Move groff &
  python-docutils from here…
  [native-inputs]: …to this new field.

or

  * gnu/packages/version-control.scm (cgit)[inputs]: Move groff &
  python-docutils from here…
  [native-inputs]: …to here.

although to be honest, I only ever use the latter format unless 
I'm feeling particularly pedantic.

> [inputs]: Move groff & python-docutils to native-inputs.

If we run

  $ guix gc --references `guix build cgit`

we can see that both groff and python-docutils are part of cgit's 
closure.  This means they must to be able to run… at run time :-o 
Oh dear.

python-docutils's ‘rst2html.py’ is required by cgit's 
/lib/cgit/filters/html-converters/rst2html, and groff itself by 
cgit's /lib/cgit/filters/html-converters/man2html.  Both of these 
uses look legitimate to me: they weren't accidentally captured by 
a stray environment variable or overzealous wrapper.

Now, it's still possible that either or both of these dependents 
must *also* run at build time, and for that they would need to be 
native indeed.  Unfortunately:

  $ guix build cgit --target=mips64el-linux-gnu
  guix build: error: gnu/packages/python-xyz.scm:2950:2:
  python-docutils@0.16: build system `python' does not support 
  cross
  builds

I could ignore that and pretend that all Python packages are 
safely architecture-independent (they're not) to continue 
investigating, but I'm out of time.

I don't think this particular patch adds any value at this time, 
so let's drop it.

The rest LGTM!

Kind regards,

T G-R

Hello Vincent,

python-docutils provides rst2html.py that seem to be used at run-time
(see patch-absolute-file-names phase).

So I think it should be an input not a native-input.

Thanks,

Mathieu

I think that "perl" might also be a native-input. Could you check it?

This one LGTM but it doesn't apply on master. Could you please send an

Both are used at run-time to make the pretty HTMLs, so I think 
this patch can be dropped.

Hm.  I don't think it's correct.  Perhaps this was in the context 
of one specific case where making something native had this 
pleasant side effect?

It's certainly not the reason native-inputs and inputs exist.

If not never, as a happy side effect at best.

Doing anything for its side effect while being unaware of their 
potentially significant main effects is a recipe for ruin.

So yes, I think you're using the right word.  I was certainly 
talking about closure myself, so that doesn't change my points 
above.

You're correct that the size of an ISO (or VM, container, …) is 
nothing more than the ‘final closure’ over all the store items 
that it contains.

> Still learning...

Of course!  This is something that confuses *many* people 
initially, until it finally clicks.

Below this mail, I'm attaching a draft of the response I'd written 
to your first message in this thread.  I abandoned it due to time 
constraints.  It's… rough, and I've explained this much better on 
IRC at least once, but maybe it can help.

Kind regards,

T G-R

The linter doesn't mention size at all, so there's a hidden (but
common) assumption above: that

- ‘inputs’ is just a fancy word for ‘run-time dependency’, and
- ‘native-inputs’ is just an obscure way to say ‘build-time 
  dependency’.

It's very important that you understand that neither of those is 
true.

It might help to think of Guix as two completely separate things:

1. a functional package builder that takes a package recipe and
   its various inputs (mainly source & {native-,}inputs), builds
   it, and saves the output to /gnu/store/<hash>-package.

   While it's true that build-time-only dependencies are often
   native-inputs, and run-time dependencies should probably be
   regular inputs, the two aren't equivalent

2. a functional package manager that only deals with the items
   (build artefacts) that it finds in /gnu/store.  It's important
   to note that this part does *not* deal with package recipes at
   all!

   The notion of a run-time dependency in Guix is simple and
   brilliant[0]: does the string ‘/gnu/store/<hash>-foo’ appear
   anywhere in ‘/gnu/store/<hash>-bar’?  If so, then foo is a
   dependency of bar because bar ‘refers’ to foo.  That's it.

   This side of Guix's personality doesn't care about package
   recipes *at all*.  Which is good, since it needs to deal
   with store items whose package recipes have long vanished.
   Therefore, it can't know or care which ‘/gnu/store/…’ strings
   it finds were once native, and which weren't.  Nativeness

This is a vast oversimplification (no mention of .drvs and of 
course
Guix can't be simply chopped in half Solomon-stylee), but it's 
been
helpful before.  I've also ignored propagated-inputs, which is 
fine.

> Is there a way to see any benefit from these changes
> (without building a vm or container image each time) ?

The benefit is that, if your changes are correct, it will (help) 
fix cross-compilation.

You can always try that yourself with

  $ guix build --target=mips64el-linux-gnu sudo

Guix will build/install a cross-toolchain the first time, which 
will take a while, but after that you'll be building just regular 
packages at roughly the same speed.

When not cross-compiling, there's no difference at all:

- With groff as a regular input:

  $ guix build sudo
  …
  environment variable `PATH' set to 
  `…:/gnu/store/hhwzz…-groff-1.22.4/bin:…'
  environment variable `LIBRARY_PATH' set to 
  `…:/gnu/store/hhwzz…-groff-1.22.4/lib:…'
  …

- Now let's make groff as a native-input: surely this will have an
  effect on, say, which libraries we're allowed to link against?

  $ guix build sudo
  …
  environment variable `PATH' set to 
  `…:/gnu/store/hhwzz…-groff-1.22.4/bin:…'
  environment variable `LIBRARY_PATH' set to 
  `…:/gnu/store/hhwzz…-groff-1.22.4/lib:…'
  …

Nope.  That's right: when not cross-compiling, all your precious 
native-vs.-not distinctions are tossed in the bin before the build 
has even started.

> Are those changes useful to do on their own ?

Absolutely!  Making groff native here is the right thing to do. 
You just got distracted by something as irrelevant as size ;-)

Kind regards,

T G-R

Thanks a lot, Tobias, for this explanation, I certainly had
some of those assumptions. It may not completely enlighten
me at the first reading, but it certainly helps knowing that "it's
more complicated" than what I assumed.
