This whole zstd replacement seems like a hazardous idea, because of backporting SRPMs to older operating systems for EPEL compilation. It's possible, but awkward, to chew through the git repos to deduce whch git branch was used and reference that, rather than directly extract from the SRPM. It would mean that unless this compression is only applied to limited uses such as drpm, then older OS releases would not be able to read the modern SRPM by default. Backwards compatibility is not why people write new software, but broad accessibility of the source code seems a vital feature to preserve for what should be rock stable build environments downstream. I, for one, have done considerable backporting of Fedora SRPMs of python modules to RHEL and CentOS environments. I'd hate to add another step to extract them on RHEL or CentOS or to build from them in "mock". I'd also hate for "rpm2cpio" to break: I hope adding zstd compatibility to the older versions of that tool, as well, is not difficult. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
