The POWERLOADER

This is a tool to download large files. This is to be used in mamba and potentially other package managers. It's a port of librepo, but extends it in several ways as well as being cross-platform (it should support Windows as well).

Current features are:

• Mirror support and automatic mirror selection
• Native OCI registry and S3 bucket support
• Resumable downloads
• zchunk support for delta-downloads

In the future this might be directly integrated into the mamba codebase -- or live seperately.

Try it out

Install dependencies (remove zchunk on Windows or where it's not available):

mamba env create -n powerloader -f environment.yml

Then you can run

conda activate test

mkdir build; cd build
cmake .. -GNinja
ninja

./powerloader --help
