FWIW, I asked Panu about this, and this was his reply: For the casual "rpmbuild -ba foo.spec" usage, querying from within a build is what I consider "mostly harmless". However in the Fedora context, where packages will be built within a chroot with no guarantees about the rpm version outside vs inside the chroot, it WILL break sooner or later due to db environment mismatch. Eg if RHEL 4 was used as the build host, in FC[567] (or thereabouts) chroot the query would fail. Mock *could* of course clear the environment (the infamous 'rm -f /var/lib/rpm/__*') before entering the chroot and after exiting it to avoid the issue. Or one could configure them to use DB_PRIVATE locking, but lets not go there... :) ***** So, basically, don't do it. We can't be sure it is safe, or predictable, and we know there are at least some failure cases. ~spot, breathing calmly, slowly -- Fedora-packaging mailing list Fedora-packaging@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-packaging
