Subject: [Rpm-metadata] adding different compression types to
createrepo
Content-Type: text/plain; charset="iso-8859-1"
Hello, I'm new to the list, but not new to using createrepo and yum for
repo
creation.
I'm looking to find if there are not patches out there to add an option to
calling for lzma or xz compression of the metafiles instead of gzip. I have
seen what opensuse uses to compress the primary.xml in conjunction with
the
gzip compression and I have extended on it to compress the other and
filelists files too, but they don't really add clean functionality.
Regards,
Matthew Dawkins

That would be https://features.opensuse.org/309167 I think,
but see also http://duncan.mac-vicar.com/blog/archives/537
/and http://lists.baseurl.org/pipermail/yum/2009-April/022560.html)
and some other discussion about using YAML and/or LZMA for repodata.
I think the extended opensuse patch should be acceptable, where it
uses "primary" for .xml or .xml.gz and the new "primary_lzma" key
for .xml.lzma or .xml.xz - plus the same added for "filelists_lzma"
and "other_lzma", it causes less breakage than changing "primary"...

*******************************************

Well, I'll add the URL to my rediffed patch. It would be nice to drop the
hybrid from making both compression types files and just use one or the
other.

http://dev.unity-linux.org/projects/unitylinux/repository/entry/packages/createrepo/P/createrepo-0.9.8-add-lzma-option-to-generate-primary.xml.lzma.patch

I tried to do it with little luck. I believe the creation of the checksum
for other than gzip files present is needed and then not appending the the
primary,other,filelists_lzma, but rather just that info instead inside
repomd.xml.
