[Feature]: Resume downloads

[radiumatic]

Hi,
Currently, if dnf or the connection is interrupted, dnf starts the download over. This is specially problematic in unstable networks. You don't want to restart a 200MB download with a very slow connection.

Curl definitely supports resuming downloads. If compatibility is the concern, the accept-ranges header can be checked to ensure the mirror webserver supports this feature. Adding an option to only download from mirrors that support it would also be great.

Assuming that every mirror serves the same binary, it wouldn't cause any problem when switching mirrors.

Please consider this issue with dnf5 as well.

Hi, I believe this is a duplicate of the librepo issue, which you can find here: rpm-software-management/librepo#293. Since both dnf4 and dnf5 use librepo as the backend, it's a common issue.

It seems to be the case, however, the file gets removed also when the connection is interrupted or "suddenly closed". I didn't find any mention of this in that issue.

Thanks, I've linked this use case in that issue. I'll close this one now.
