Description Ben Beasley 2022-10-15 12:51:58 UTC

The edflib package does not support big-endian architectures, which impacts s390x.

This was brought to upstream’s attention in https://gitlab.com/Teuniz/EDFlib/-/issues/9, and a nontrivial patch was offered in https://gitlab.com/Teuniz/EDFlib/-/merge_requests/1. Upstream declined the patch, citing concerns about performance, testing, and necessity.

Since then, the Fedora package has carried the declined PR as a downstream patch for s390x only.

With upstream release 1.23, “non-support” of big-endian architectures is explicitly documented, and endianness is checked at runtime: https://gitlab.com/Teuniz/EDFlib/-/commit/b931e24744bd9e1e3161e20754ac23484e1e2452

Therefore, beginning with version 1.23 in Rawhide/F38, the Fedora package will drop the downstream patch and stop building edflib for s390x. Since edflib is currently a leaf package, there will be no impact to other Fedora packages.

Note that edflib should not be confused with python-pyedflib, which uses a bundled fork of edflib and which has never supported s390x (bug 2027046).

Closing as WONTFIX since this is an upstream design decision now baked into the API and error codes.
