Software Heritage lister

Project description

swh-lister

This component from the Software Heritage stack aims to produce listings of software origins and their urls hosted on various public developer platforms or package managers. As these operations are quite similar, it provides a set of Python modules abstracting common software origins listing behaviors.

It also provides several lister implementations, contained in the following Python modules:

  • swh.lister.bitbucket
  • swh.lister.debian
  • swh.lister.github
  • swh.lister.gitlab
  • swh.lister.gnu
  • swh.lister.pypi
  • swh.lister.npm
  • swh.lister.phabricator
  • swh.lister.cran
  • swh.lister.cgit
  • swh.lister.packagist

Dependencies

All required dependencies can be found in the requirements*.txt files located at the root of the repository.

Local deployment

lister configuration

Each lister implemented so far by Software Heritage (github, gitlab, debian, pypi, npm) must be configured by following the instructions below (please note that you have to replace <lister_name> by one of the lister name introduced above).

Preparation steps

  1. mkdir ~/.config/swh/ ~/.cache/swh/lister/<lister_name>/
  2. create configuration file ~/.config/swh/lister_<lister_name>.yml
  3. Bootstrap the db instance schema
$ createdb lister-<lister_name>
$ python3 -m swh.lister.cli --db-url postgres:///lister-<lister_name> <lister_name>

Note: This bootstraps a minimum data set needed for the lister to run.

Configuration file sample

Minimalistic configuration shared by all listers to add in file ~/.config/swh/lister_<lister_name>.yml:

storage:
  cls: 'remote'
  args:
    url: 'http://localhost:5002/'

scheduler:
  cls: 'remote'
  args:
    url: 'http://localhost:5008/'

lister:
  cls: 'local'
  args:
    # see http://docs.sqlalchemy.org/en/latest/core/engines.html#database-urls
    db: 'postgresql:///lister-<lister_name>'

credentials: []
cache_responses: True
cache_dir: /home/user/.cache/swh/lister/<lister_name>/

Note: This expects storage (5002) and scheduler (5008) services to run locally

lister-github

Once configured, you can execute a GitHub lister using the following instructions in a python3 script:

import logging
from swh.lister.github.tasks import range_github_lister

logging.basicConfig(level=logging.DEBUG)
range_github_lister(364, 365)
...

lister-gitlab

Once configured, you can execute a GitLab lister using the instructions detailed in the python3 scripts below:

import logging
from swh.lister.gitlab.tasks import range_gitlab_lister

logging.basicConfig(level=logging.DEBUG)
range_gitlab_lister(1, 2, {
    'instance': 'debian',
    'api_baseurl': 'https://salsa.debian.org/api/v4',
    'sort': 'asc',
    'per_page': 20
})
import logging
from swh.lister.gitlab.tasks import full_gitlab_relister

logging.basicConfig(level=logging.DEBUG)
full_gitlab_relister({
    'instance': '0xacab',
    'api_baseurl': 'https://0xacab.org/api/v4',
    'sort': 'asc',
    'per_page': 20
})
import logging
from swh.lister.gitlab.tasks import incremental_gitlab_lister

logging.basicConfig(level=logging.DEBUG)
incremental_gitlab_lister({
    'instance': 'freedesktop.org',
    'api_baseurl': 'https://gitlab.freedesktop.org/api/v4',
    'sort': 'asc',
    'per_page': 20
})

lister-debian

Once configured, you can execute a Debian lister using the following instructions in a python3 script:

import logging
from swh.lister.debian.tasks import debian_lister

logging.basicConfig(level=logging.DEBUG)
debian_lister('Debian')

lister-pypi

Once configured, you can execute a PyPI lister using the following instructions in a python3 script:

import logging
from swh.lister.pypi.tasks import pypi_lister

logging.basicConfig(level=logging.DEBUG)
pypi_lister()

lister-npm

Once configured, you can execute a npm lister using the following instructions in a python3 REPL:

import logging
from swh.lister.npm.tasks import npm_lister

logging.basicConfig(level=logging.DEBUG)
npm_lister()

lister-phabricator

Once configured, you can execute a Phabricator lister using the following instructions in a python3 script:

import logging
from swh.lister.phabricator.tasks import incremental_phabricator_lister

logging.basicConfig(level=logging.DEBUG)
incremental_phabricator_lister(forge_url='https://forge.softwareheritage.org', api_token='XXXX')

lister-gnu

Once configured, you can execute a PyPI lister using the following instructions in a python3 script:

import logging
from swh.lister.gnu.tasks import gnu_lister

logging.basicConfig(level=logging.DEBUG)
gnu_lister()

lister-cran

Once configured, you can execute a CRAN lister using the following instructions in a python3 script:

import logging
from swh.lister.cran.tasks import cran_lister

logging.basicConfig(level=logging.DEBUG)
cran_lister()

lister-cgit

Once configured, you can execute a cgit lister using the following instructions in a python3 script:

import logging
from swh.lister.cgit.tasks import cgit_lister

logging.basicConfig(level=logging.DEBUG)
# simple cgit instance
cgit_lister(url='https://git.kernel.org/')
# cgit instance whose listed repositories differ from the base url
cgit_lister(url='https://cgit.kde.org/',
            url_prefix='https://anongit.kde.org/')

lister-packagist

Once configured, you can execute a Packagist lister using the following instructions in a python3 script:

import logging
from swh.lister.packagist.tasks import packagist_lister

logging.basicConfig(level=logging.DEBUG)
packagist_lister()
