[zypp-devel] [PATCH 0/2] Support for primary.xml.lzma (fate#309167)
Hi, this series tries to implement fate#309167. In short: The 11.2+ kernel provides a dependency for each exported symbol (fate#305945), which results in thousands of provides. Zypp / sat-solver cope well with this, but the problem is that the primary.xml.gz file grows beyond limits. This is especially an issue in the update repository, which contains also previous versions of released updates (bnc#582907). The idea is to sort the entries in primary.xml and provide a lzma-compressed version allongside with primary.xml.gz, e.g.: <data type="primary"> <checksum type="sha256">5af6293d33986c74084639d228cab0eb66dcd16e1b2782e79447520055a256ee</checksum> <timestamp>1272657997</timestamp> <size>1747219</size> <open-size>12401312</open-size> <open-checksum type="sha256">c450888395ecc54345a0d0bc152b5bc774cea727e9d285bf6d88dda2d6bc0e0c</open-checksum> <location href="repodata/primary.xml.gz"/> </data> <data type="primary_lzma"> <checksum type="sha256">e15e7b0ae7756ca345580f5639f3512bcdfe23aa21c0355a7147af356a18bf22</checksum> <timestamp>1272657997</timestamp> <size>750408</size> <open-size>12401312</open-size> <open-checksum type="sha256">c450888395ecc54345a0d0bc152b5bc774cea727e9d285bf6d88dda2d6bc0e0c</open-checksum> <location href="repodata/primary.xml.lzma"/> </data> The createrepo changes are in http://gitorious.org/mmarek-misc/createrepo/commits/lzma-support, a package is in home:michal-m:branches:system:packagemanager/createrepo. These two patches change zypp to skip downloading primary.xml.gz if primary.xml.lzma is available. A third patch against sat-solver adds support for primary.xml.lzma to repo2solv.sh. libzypp.spec will need a versioned requires on satsolver-tools so that an up-to-date repo2solv.sh script is available. This part is not included. Please review, it would be great to have support for this in 11.3.

I'm not really in favor of this. I would rather have zsync downloads for primary, which would need a "rsyncable" compression format, i.e. "gzip --rsyncable".

Yes, but I hope that's not the ultimate solution.

I see pros and cons of both approaches (rsyncable primary.xml.gz would probably result in smaller incremental updates, with primary.xml.lzma, the first download would be smaller) and I don't really insist on either solution. But support for primary.xml.lzma is indeed trivial to add, I have no idea how much effort would zsync support take.

Michael, is there chance of having zsync support in 11.3? Thanks, Michal -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

Michael,
is there chance of having zsync support in 11.3?
It'll be my Hackweek project. I doubt that this is early enough for 11.3, though.
