I've made several experiments in order to find a better way to list arch linux package.

Updating D7812: [WIP] Add arch lister module.

Updating D7713: crates: rework to take advantage of data returned by the crates lister

Update back the diff

Add 'Franck Bret' to contributors

prepare to push

Updating D7501: Rust lang, Crates loader

Updating D7654: crates, create one origin per package instead of per version

Add missing "v1" in http api url

Added 'version' key to 'artifacts' dict.

Nice, and now the loader needs some rework to match that diff's adaptations ;)

I've run the lister in the docker environment, it looks good.

Updating D7654: Crates.io lister, create one origin per package instead of per version

Refactor crates.io lister

Ok, but what will be the usage of versioned artifacts as extra_loader_arguments?

We don't want to create one origin per version of a package.
We want all versions of a packages seen under the same origin (well, at the time of the ingestion).

See this thread where we made the mistake for the maven ingestion [1]

Is that possible at all for the rust ingestion?

Cheers,

wait... we are creating one origin for each version of the crate?

Yes it is.

I guess Instead of returning an url for a version (i.e: https://static.crates.io/crates/{package_name}/{package_name}-{version}.crate ) lister should return an http api url (i.e : https://crates.io/api/v1/crates/{package_name} ) ?

Yes, this one.

And i'd say, return the list of associated versioned artifacts as extra_loader_arguments.

@vlorentz thoughts?

Once @vlorentz's comment is adressed (we should list one origin, the package i guess, and
gather all crate versions under that same origin).

Make sure your commit message (one to one with the diff description) is one short
summary (in imperative form) [1]. For some extra description, use multiple lines.

In D7501#199444, @ardumont wrote:

yes, rename to package_name, the other change would make for a much wider impact (than you probably want to deal with ;).

It would not. The get_loader function is not used anywhere outside of this cli.py

right, nvm then.

I was thinking of something else (iirc, there is something similar in the lister or something)

i'd prefer that renaming nonetheless though, it's more explicit.

Refactor according to @vlorentz & @ardumont comments.

fix missing whitespace in loader specification documentation

Add crates package loader specification

Not sure you have seen this comment before, and because its an important point to go further, I repost :

Trying another alternative to make mypy happy (don't get why got no error in dev env running tox -e mypy or mypy -c mypy.ini but fail on CI..)

mypy multiline ignore fix

Rebase upstream

Fixes after ardumont and vlorentz review

Some fixes after @Alphare review. Mainly add 'name' and 'version' to loader args as those are given through the 'extra_loader_arguments' from lister.

One important thing to note after adding 'name' and 'version' args is that it does not work with the CLI in the docker environment..

franck@debian-franck:~/workspace/swh-environment/docker$ docker-compose exec swh-loader swh loader run crates "https://static.crates.io/crates/micro-timer/micro-timer-0.4.0.crate" version="0.4.0" name="micro-timer"

Traceback (most recent call last):

  File "/src/swh-loader-core/swh/loader/cli.py", line 104, in run
    loader = get_loader(type, url=url, storage=conf["storage"], **kw)
TypeError: get_loader() got multiple values for argument 'name'

What do you think about that ?
Better renaming 'name' to 'package_name' in the crate lister and loader or should the cli arg evolve to something like 'loader_name'?

Here is a first crates.io loader.

Rebase

lister: Add new rust crates lister

Hi, thanks you all for the review.

Fixes after first code review
