RPM repository metadata parser.

repomd-parser's Issues

Additional fields when parsing primary.xml

Hallo @ikapelyukhin 👋

I started looking into this gem and maybe using it for SCC. Looks super promising, but I just noticed that parsing a primary doesn't return all the fields we'd need, like summary, description, license.

Can we have these? Anything planned here already? I can do a draft PR, just wanted to ask your opinion. Should I just add parsing these fields always, or attempt something like optional "extra_fields"?

Thanks!

missing support for decoding `.zst` compressed repository metadata

There's handling for gzip here:

https://github.com/ikapelyukhin/repomd-parser/blob/ec7ffdcc50458f9825f456c5f026079e0da27dfb/lib/repomd_parser/base_parser.rb#L29C1-L32

however no corresponding handling for .zst (ZSTD) compression. ZSTD is the default compression type created by createrepo_c >= 1.0.0 and many distributions (Fedora, openSUSE) are switching to it because of the higher compression ratios and much higher decompression speed.

Question: Support for StringIO

Are there plans for supporting StringIO? The use case is: not persisting to disk the downloaded XML.

response = http_client.get('https://a-webserver.here/repodata/primary.xml.gz')
response.body.class # => string

# Then I'd have to persit it on disk here
File.write('primary.xml.gz')
entries = RepomdParser::PrimaryXmlParser.new('primary.xml.gz').parse

But it looks like it doesn't play well in overlayfs as we're hitting DiskPressure sometimes, it'd be ideal not to have to persist it in disk 🤔
