[bug#73073] [PATCH 0/6] Allow origin with label as inputs.

[Simon Tournier]

Hi,

As discussed in bug#73034 [1], these 5 packages – farstream,
gnulib-checkout, smithforth, gnome-recipes and dmd-bootstrap – have an
origin inside the ’arguments’ package record.

This is annoying because these origins are hidden from
’package-direct-sources’; see module (guix packages).

I consider this is bug. :-)  Hence this prposal for fixing it.

Moreover and tangentially, it appears to me an anti-pattern of the
functional paradigm: The data from the impure outside should be handled
by the ’source’ record field, or otherwise by ’inputs’, ’native-inputs’
or ’propagated-inputs’ record fields; let say only ’inputs’ for
simplicity.

To my knowledge, using the old style with label, we strove on this
principle.  However, using the “new style” [2], it does not offer to
have labels with plain package symbol.  In other words, for example,
this snippet does not work:

      (list gdmd which
            `("phobos"
              ,(origin
                 (method git-fetch)
                 (uri (git-reference
                       (url "https://github.com/dlang/phobos")
                       (commit (string-append "v" version))))
                 (file-name (git-file-name "phobos" version))
                 (sha256
                  (base32
                   "1yw7nb5d78cx9m7sfibv7rfc7wj3w0dw9mfk3d269qpfpnwzs4n9"))))))

The reason is because ’sanitize-inputs’; see module (guix packages).

    ((_ (list args ...))
     (add-input-labels args ...))
    ((_ inputs)
     (maybe-add-input-labels inputs))))

Roughly speaking, because the ’inputs’ starts by the term ’list’ then
’add-input-labels’ is applied, else it applies ’maybe-add-input-labels’.

Note that:

    (define (add-input-labels . inputs)
      "Add labels to all of INPUTS if needed (this is the rest-argument version of
    'maybe-add-input-labels')."
      (maybe-add-input-labels inputs))

The procedure ’maybe-add-input-labels’ reads: if the first element of
the ’inputs’ record field is using the “old style“ then return all
as-is, assuming all are “old style”.  Else apply to all the ’inputs’
elements the procedure ’add-input-label’.

Hence the simple proposal:

+     `(,label ,obj))
     (x
      `("_" ,x))))
--8<---------------cut here---------------end--------------->8---

This allows to write ’inputs’ as above. :-)  As done with the 5 packages.

And it does not hurt the new style.  Maybe “guix style” would need to be
adjusted too?

WDYT?

Cheers,
simon

I can see why you're doing that, but I'm not really convinced it helps
the package.  Particularly, we're now even adding a labeled input,
which makes for a cursed situation where all but one inputs are
unlabeled¹.

IMHO, G-Expressions in phases serve in part to facilitate uses like
this.  They may not be nice, but those are upstream conditions we have
to cope with.  I'd rather do a proper unbundling of libgd.

Another "proper" solution could be as easy as using an unlabeled origin
and search-input-file.  However, this doesn't really work all that well
if you have to unpack the entire origin, hence what I've done here for
gnome-recipes.

Cheers

¹ Let's not even mention the necessity of 1/6 to enable that.  Back in
the day, there was a decision against giving origins labels because it
would add to the further propagation of label use throughout Guix,
while we want to drop them.

[Simon Tournier]

Hi Liliana,

My aim is not to mix, under ’inputs’ record field, the old style (label)
with the new style (no label) but to have the ’origin’ inside ’inputs’
and not inside ’arguments’.

As I wrote in the cover letter:

        This is annoying because these origins are hidden from
        ’package-direct-sources’; see module (guix packages).

So it helps the package. ;-)

Please note that the docstring of ’package-direct-sources’ is currently
lying. ;-)  Well, the situation is a bug, IMHO.

I agree that G-exps facilitate manipulation of store paths.  But using
’origin’ inside arguments appears to me as an abuse of the feature.  As
I wrote in the cover letter:

        Moreover and tangentially, it appears to me an anti-pattern of the
        functional paradigm: The data from the impure outside should be handled
        by the ’source’ record field, or otherwise by ’inputs’, ’native-inputs’
        or ’propagated-inputs’ record fields; let say only ’inputs’ for
        simplicity.

Therefore, I strongly think ’origin’ should not be inside arguments.

Somehow, my submission is a proposal for dealing with the case.  And
it’s not really if it needs to, or should, be done. :-)

Please note it’s a specific inputs: it’s an ’origin’.  This can be
checked by the pattern matching, e.g.,

    (((? string? label) (? origin? o) ;Allow old style as sometimes requires by origin in inputs
     `(,label ,o))

Other said, it would not be a “cursed situation”; only a situation using
a locally defined input.

Sure, but you do introduce a label to make that work is what I'm
saying.

I think we should fix ‘package-direct-sources’ then.  The derivation
obviously knows about this input, otherwise the package wouldn't be
built, so the information is there.  I'd also hazard a guess that Rust
being Rust, no useful information for Rust packages comes with package-
direct-inputs if arguments aren't being handled.

We could handle it in source at the cost of similar anti-patterns, or
in inputs at the cost of the anti-pattern you suggest.  The Right
Thing™ would be to unbundle these dependencies correctly.

Also note that your argument would apply to #$this-package-input just
as well: it still is magic that pulls in data from the impure outside
world, and you can trivially trick it into doing silly things.  (Just
add inheritance.)

You are working on the implicit assumption that everyone agrees that it
needs to be done, then.

It *is* a cursed situation for the person reading the inputs field. 
Apart from proper unbundling, some other workarounds would be:
- hacking around search-input-file
- making dummy data packages
- named origins (this one requires similar support code to be written
  and has already been rejected once IIRC)
- computed origins
And yes, I label them as workarounds, since they don't address the root
cause of why origins are introduced in arguments.

Sometimes, practicality beats purity: Consider the ungoogled-chromium
recipe if you hadn't had a good scare today.  The fact that this
pattern shows up as rarely as it does is a testament to how well Guix
functions otherwise – but there might still be a need for it in some
fringe circumstances.  I'd rather we don't change code unless the
result is clearly better™, and I don't see that here.

Cheers

Yes: as an optimization, we just check the first element or even just
the syntax (whether the value starts with (list …)).

This is one reason why I’d rather avoid the change you’re suggesting.
But more importantly: I think we should avoid polymorphic lists for
clarity (the principle is followed in most of the code), and
reintroducing labels would be a step backwards.

To be clear, I understand the current situation is not perfect, but I
would rather look for solutions that do not involve undoing what’s taken
this long to do.

The main issue we want to address here is origins being hidden from
‘package-direct-sources’, right?

What if we could do this:

?  (Currently we can’t because ‘gexp-inputs’ is private.)

Or, alternatively, we’d have origins without labels in inputs, with

Yes, I am aware of the Rust package case. :-)

It’s similar as the Haskell
package, as I pointed years ago [1].  I still think that’s something
which needs to be improved.

This is inaccurate: inputs are already polymorphic lists.  For example,

    (native-inputs (list desktop-file-utils ;for update-desktop-database
                         gettext-minimal
                         `(,glib "bin")
                         itstool
                         pkg-config
                         python))

And “bin” is a label, AFAIU.  That’s said…

…I agree: my aim is not to revive the “old style”.  Aside, from my
perspective, the main issue with the “old style” is not the labels but
instead it’s the redundancy.

In other words, labels are not the evil since they are still used for
dealing with “outputs”.

Anyway, let avoid the Walder’s law trap [1]. ;-)

So let do not rely on explicit labels.

> The main issue we want to address here is origins being hidden from

Yes…  And also I think that’s a bad pattern to not have all “inputs“ in
the same place. From my point of view, the current situation defeats my
understanding of declarative programming.

This solution appears to me the best approach.  Somehow, it uses
’file-name’ as internal “label”.  When internal “labels” will completely
removed, e.g., using package name or else, we will adapt.

Well, ’origin-actual-file-name’ returns for example
"libgd-2.0.4-checkout", i.e. the version would be required when calling
’this-package-input’.  Therefore, it would mean something like:

    #$(this-package-native-input (git-file-name "libgd" version))

This appears to me a good solution.

However, how is it possible to avoid a full rebuild because ’tzdata’ or
else?  It means the package definition cannot be modified, right?
Therefore, the only way would to special case ’maybe-add-input-labels’,
e.g.,

--8<---------------cut here---------------start------------->8---
@@ -441,6 +441,9 @@ (define (maybe-add-input-labels inputs)

Would it be ok performance-wise?  Or what could the another option?

Moreover, as you said some other packages deep in the graph seem in the
picture.

Well, I am going to explore this in order to send a v2.

Not in the sense that you are addressing inputs with it, no.  "bin" is
an output selector (output "label" if you will) – its purpose it to
choose an output that isn't "out".

But you are adding explicit labels here.  A solution that doesn't would

I agree with you that inputs outside of inputs should be avoided, but I
disagree with your point on declarative programming.  Packages, even
written in that style, are still declarative.

It doesn't to me.  What do you do if the libgd version changes?  To
arrive at a proper label, you would have to strip the versioning and
packaging metadata – otherwise you're left with a situation, where you
can't replace the package by tweaking inputs anyway.

I don't think this does what you think it does.
It returns inputs as-is if the tail of the first input is an origin…
which I don't think would be the case even if we do implement your v1.

[bug#73073] [PATCH v2 0/8] Allow origin inside inputs with "new style".

[Simon Tournier]

Hi,

Following Ludo's advice [1], here the v2.

Packages use ’package-name’ as internal labels so the first patch of the serie
adds ’origin-actual-file-name’ as internal labels for the origins.  Then, the
’origin’ is found back via ’this-package-input’ as for the packages.

For instance, without the patch, we have somewhere in the phase:

        #$(origin
            (method url-fetch)
            (uri (string-append
                  "mirror://kernel.org/software/scm/git/"
                  "git-manpages-" (package-version this-package) ".tar.xz"))
            (sha256
             (base32
              "1lvvhzypllbyd8j6m0p9qgd3gqg10gch9s7lqif8vr9n80fqn4fw"))))))))))))

then with the patch, this origin is moved to the ’native-inputs’ field and the
snippet above is replaced by:

        #$(this-package-native-input
           (string-append
            "git-manpages-" (package-version this-package) ".tar.xz")))))))))))


Please note the two special cases: tzdata and texlive-hyphen-complete.  They
are considered in order to avoid a world rebuild.  The final adjusment can be
addressed with some “build train” (or “merge train”) as discussed elsewhere.


The other patches of the series provide more examples of the usage.

WDYT?

Cheers,
simon

[Simon Tournier]

* guix/packages.scm (add-input-label): Rely on 'origin-actual-file-name' for
internal inputs labels.
(maybe-add-input-labels): Special case to avoid world rebuild.

"libgd-checkout" would be both more honest and easier to get right.

Yes, agreed.

Of course this is ugly, but it’s IMO okay if we only have to do it for a
few packages (and for a limited amount of time).

I would rather have this hack in ‘tzdata’ itself, along the lines of
what I sent in a previous message.

I think this should be avoided, but what is it that causes a rebuild in
this case?

Yes, indeed tzdata can temporarily transformed into the old style.  It
avoids the world rebuild and it’s a modification easier to change than
the one about maybe-add-input-labels.  I agree that’s better.

It’s about the package texlive-hyphen-complete; it leads to a world
rebuild – as pointed in the cover letter of v2 ;-)

It reads:

    (native-inputs
     (list ruby-2.7
           ruby-hydra-minimal/pinned
           ;; Build phase requires "docstrip.tex" from TEXLIVE-LATEX.
           ;; However, adding this package to native inputs would initiate
           ;; a circular dependency.  To work around this, use TEXLIVE-LATEX
           ;; source, then add "docstrip.tex" to TEXINPUTS before build.
           (package-source texlive-latex)
           texlive-tex))

then:

          (add-before 'build 'include-docstrip.tex
            (lambda* (#:key inputs native-inputs #:allow-other-keys)
              (let ((docstrip.tex
                     (search-input-file (or native-inputs inputs)
                                        "tex/latex/base/docstrip.tex")))


Well, we can apply the same hack as tzdata: temporarily revert to the
old style.
