I've pushed a branch wip-rav1e to Savannah:

https://git.savannah.gnu.org/cgit/guix.git/log/?h=wip-rav1e

With this branch I can successfully (slowly!) encode AV1 video using
librav1e in FFmpeg.

I need some advice about the Rust packages. I used Martin Becze's
recursive version-aware Rust crate importer [0] to create the packages,
with some manual changes to the rav1e package.

Should they be added to (gnu packages crates-io)? And if so, should it
be done as a single commit? Or one-by-one? It's 258 new packages, and
figuring out the order they should be added in seems... too hard. So I'd
rather do it all at once.

The c-bindgen and cargo-c packages could go in (gnu packages rust-apps).

What about updating them later? Will `guix refresh` handle it? Or will I
need to re-import? In that case, would it be easier to keep them all in
their own module?

One-by-one unfortunately

They should be alphanumeric

guix refresh should  handle them. But currently it should do thing 
recursively so keep that in mind.

I have a small tool I have been working will make the new packages 
easier to commit.... its very much WIP but if I would appreciate any 
feedback. Attached is sort2.scm and merge.scm

sort2.scm will sort a files exported packages alphanumerically.
merge.scm will merge exported packages of two files into a single file 
creating a git commit for every new or updated package.

Here is my work flow,
1) Import the package using `guix import crate -r mypackage > mypackage.scm`

2) Sort the packages, `guile -s ./sort2.scm mypackage.scm > 
mypackage.scm` (you will probably also want to sort crates-io.scm, i 
think some packages may be out-of-order now)

3) merge mypackages.scm and crates-io.scm `guile -s ./merge.scm 
./mypackage.scm ./crates-io.scm`

4) check that the git log looks correct and that everything still runs! :D

Attached!

If you want to build it, make sure to adjust the module path on the
first line to match the "-sorted" filename.

Also note that I changed the variable names of the first two packages,
cargo-c and rav1e, from what the importer named them. But I tried
changing them back and it didn't seem to help.

You need to remove the "(use-modules ..." from rav1e-sorted.scm, it 
should only have package definitions into.

Ill also find away to handle that more elegantly

Ah, I see! After removing that, the merge.scm script does run.

However, it does not successfully handle inherited packages, doing
things like removing rust-aho-corasick-0.7 even though
rust-aho-corasick-0.6 inherits from it.

Additionally, the commit diffs it creates are a little suspicious, for
example see below, which seems malformed.

Handling inheritance could be tricky, I have fully thought that part though.

I've been working on this and I've committed about 3000 lines of these
packages by hand.

But, I have a concern with committing these packages one at a time
alphabetically.

Since the packages refer to each other, committing them individually
breaks the build until the entire commit series is complete. This will
break `git bisect` for 267 commits (the number of packages).

I think it would be better to add the new crates alphabetically in a
single commit.

Hi Leo,

You should be committing packages in topological order but the file order is alphabetical. 

Good luck, rust is a ton of work.

Okay, that makes sense.

I tried to use `guix graph` to learn the shape of the package graph but
it doesn't work as expected since these packages don't refer to their
dependencies in the typical way. I thought that using the 'derivation'
graph type might help but I don't think that I can process it on my
computer `dot`. It's been going for hours now...

Many of the "new packages" are actually semver-compatible updates to
existing packages, and these updates often change the list of
cargo-inputs dependencies.

Given that, I don't know how to learn the right order of things to
commit one at a time that will never break the build.

Would we have the same issue with updating this kind of large package
tree automatically with `guix refresh` and committing the changes one at
a time?

This is at least partially my fault; I suggested that the packages be
sorted alphabetically after a recursive import. It works well for adding
them all in one channel, not so well for adding them piecemeal to Guix.

This is because we technically use the package-source of the packages,
not the packages themselves.

Short of resorting them I'd start with ones that have no dependencies,
just rely on rust-quote & friends or are older versions. Some packages,
like rust-futures-*, should be updated as a group since they all expect
to be the same version.

The only real builds that we care about are the packages in rust-apps
and librsvg-next (and librsvg-next is less important). And of course
that we don't reference packages that don't exist yet.

The ones that I spend the most amount of time reviewing are the ones
that end in -sys or otherwise reference system libraries. Sometimes more
effort is needed to unbundle libraries. In general anything that wants
rust-{cc,cmake,pkg-config} is suspect.

Sometimes. We do have other upgrades where we go and do a bunch at once,
where they rely on each other and expect specific versions. The first
thing I can think of is certbot.

Right, but keeping Guix building without "undefined variable" warnings
is what I'm worried about here.

Hm... you're saying they sometimes bundle C / C++ language libraries?

Certbot is special in the sense that certbot and python-acme are
actually developed in the same Git repo but are split up for PyPi
distribution in the hope that other projects will build on python-acme.

I'm wondering if I can just push the crates as a single commit, after
inserting them alphabetically and fixing any cosmetic issues, and also
handling the semver-compatible package updates.

I know that we don't usually do this when adding packages to an existing
module. We do add packages en masse when creating a new module.

The reason I'm asking to make an exception to our policy of one package
or update per commit are that it will be a ton of work (several full
days at least) to add software that is already working fine on the
wip-rav1e branch.

I don't see what value this additional labor will give to Guix users,
including developers. At least, I don't think the value of individual
commits will outweigh the value of my labor in this case.

What do you all think?

Just search for snippet in (gnu packages crates-io). rust-bzip2-sys was
particularly bad and basically needed to be replaced, but expat-sys,
jemalloc-sys, libgit2-sys, libssh2-sys etc all bundle the library.

There are a couple of those in rust-land too.

It took me about 3 weeks to review ~270 patches for alacritty and it was
easily more than 20 hours.

I suppose it's not that much different than updating all the GHC
packages in one go, except that they're more interconnected. I suppose
we could throw them all into the crates-io module and then hack on all
270 packages at once in a separate branch. That certainly would be easier
than adding them one at a time.

Yeah I have also wondered this. I think it would make things a lot 
easier if we could do single commits.

I'm working on packaging rav1e for Guix again and so I'm using sort2.scm
on the big 'gnu/packages/crates-io.scm' module.

One problem I noticed with sort2.scm is that inherited packages need to
be after the package they inherit from, but this means they will not be
alphanumerically sorted.

For example, sort2.scm will put rust-bytes-0.3 before rust-bytes-0.4,
but then the build fails, because the former inherits from the latter
but can no longer find it.

I apologize I didn't see this message until now. I will look into this 
today.

The problem should be fixed now. You can try it out about cloning `git 
clone https://gitlab.com/mjbecze/guix-package-sorter && cd 
guix-package-sorter` then do `./pre-install-env guix sort <FILE>` to 
sort the given file. Let me know if it works!

I squashed all the cargo commits together and pushed them. I didn't push
the one with adding rav1e to ffmpeg, I wasn't sure how much that would
add to 'guix size'.

Amazing, thank you!!!

I intended the FFmpeg commit as a "demo", since we don't usually package
unreleased versions of packages, especially important things like
FFmpeg. We can add rav1e when FFmpeg officially supports it.

It's okay to delete the wip-rav1e branch now, right?

It should be ok. We have the patches already for the crate importer and
if you don't need the code for adding rav1e to ffmpeg then there's
nothing else we need there.
