If you know the other malloc impl, you can do a dnf query. For example gperftools ships the tcmalloc impl. Looking at the ELF symbol it provides, we can query for its usage thus: # dnf repoquery --whatrequires 'libtcmalloc.so.4()(64bit)' 389-ds-base-0:1.4.0.6-2.fc28.x86_64 389-ds-base-libs-0:1.4.0.6-2.fc28.x86_64 389-ds-base-snmp-0:1.4.0.6-2.fc28.x86_64 Pound-1:2.7-3.fc24.x86_64 bro-core-0:2.5.3-2.fc28.x86_64 ceph-base-1:12.2.4-1.fc28.x86_64 ceph-base-1:12.2.7-1.fc28.x86_64 ceph-common-1:12.2.4-1.fc28.x86_64 ceph-common-1:12.2.7-1.fc28.x86_64 ceph-fuse-1:12.2.4-1.fc28.x86_64 ceph-fuse-1:12.2.7-1.fc28.x86_64 ceph-mds-1:12.2.4-1.fc28.x86_64 ceph-mds-1:12.2.7-1.fc28.x86_64 ceph-mgr-1:12.2.4-1.fc28.x86_64 ceph-mgr-1:12.2.7-1.fc28.x86_64 ceph-mon-1:12.2.4-1.fc28.x86_64 ceph-mon-1:12.2.7-1.fc28.x86_64 ceph-osd-1:12.2.4-1.fc28.x86_64 ceph-osd-1:12.2.7-1.fc28.x86_64 ceph-radosgw-1:12.2.4-1.fc28.x86_64 ceph-radosgw-1:12.2.7-1.fc28.x86_64 ceph-test-1:12.2.4-1.fc28.x86_64 ceph-test-1:12.2.7-1.fc28.x86_64 gperftools-devel-0:2.6.3-2.fc28.x86_64 mongodb-0:3.6.3-1.fc28.x86_64 mongodb-server-0:3.6.3-1.fc28.x86_64 Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :| _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/C5TR22GFYAUFM34A42VREHQYDWA62FVK/
