Project description
Soufi (Source Finder) is a library that finds downloadable URLs for source packages, given the binary package name and version. It will also create a compressed archive of multiple downloadable files, or save any existing downloadable archive.
- Currently supported finders are:
Debian OS packages
Ubuntu OS packages
Red Hat (UBI) packages
CentOS packages
Alpine packages
Photon OS packages
AlmaLinux OS packages
NPM packages
Python sdists
Golang modules
Java JARs
Ruby Gems
Rust Crates
PHP PECL packages
PHP Composer packages
If you want to download Alpine packages, you must have git installed.
Requirements
Soufi is currently tested on Python versions 3.8 through 3.12. It is known not to work on 3.6.
Quickstart
Install Soufi with pip:
pip install soufi
or, with the command-line tool:
pip install soufi[cli]
Using the command line
soufi python flask 2.0.0

import soufi
finder = soufi.finder.factory(
'python', 'flask', '2.0.0', soufi.finder.SourceType.python
)
source = finder.find()
print(source)

)

print(source)
with source.make_archive() as archive, open('zlib.tar.xz', 'wb') as local:
shutil.filecopyobj(archive, local)Caching
Soufi uses dogpile.cache to provide a convenient mechanism for caching requests when doing repeated lookups. For sources with network-intensive remote discovery (e.g,, DNF/Yum-based OSes) this is strongly recommended.
For a single-threaded application, an in-memory LRU cache, should be adequate:
import pylru
import soufi
LRU_CACHE = pylru.lrucache(size=1024)
finder = soufi.finder.factory(
'centos', 'cracklib-dicts', '2.9.0-11.el7', soufi.finder.SourceType.os,
cache_backend='dogpile.cache.memory',
cache_args=dict(cache_dict=LRU_CACHE),
)
print(finder.find())
# Re-using the finder will use cached results
print(finder.find('vim-minimal', '7.4.629-8.el7_9'))More complex applications can use the other backends, e.g., memcached, Redis, custom backends, etc. See the dogpile.cache documentation for details on backend configuration.
