Subject: [PATCH] Preserve changed API for cr_compress_file_with_stat (RhBug:1973588)
In order to be compatible in rhel8 we want to preserve the old API and
behavior.
Keep the fixed version as cr_compress_file_with_stat_v2 only for rhel8

import createrepo_c-0.17.7-5.el8
2022-05-10 07:05:30 +00:00
With fixed memory leak of `tmp_err`, reported here:
