Commit b5e8db8f14d tuned the SPEC file so that libvirt daemons restart on package upgrade. In order to do that it added a bunch of parametrized macros using the %global directive. This caused a problem when running RPM builds on CentOS Stream 8 resulting in:
error: Too many levels of recursion in macro expansion. It is likely caused by recursive macro declaration. error: Macro %libvirt_daemon_perform_restart failed to expand error: line 1275: %global libvirt_daemon_perform_restart() \ if test %libvirt_daemon_needs_restart %1 \ then \ /bin/systemctl try-restart %1.service >/dev/null 2>&1 || : \ fi \ %libvirt_daemon_finish_restart %1
There are 2 important differences between %global and %define directives: 1) %define is local-only and does have scope - in reality though, its scope is apparently not really enforced because it behaves exactly the same way as %global 2) %define is evaluated at the of use while %global is evaluated at the time of definition
The latter and the fact the macro is parametrized is the reason why the RPM builds fails on CentOS. Strangely enough this only happens on CentOS Stream, but not Fedora (which is also the main proponent of replacing %define with %global). Anyhow, replacing %global with %define makes the rpmbuild to pass on both and along with package upgrades.
