Support redefining %{gitrev} RPM macro from command line.

This together with the following change to the spec file:

diff --git a/librepo.spec b/librepo.spec
index d5582db..0884735 100644
--- a/librepo.spec
+++ b/librepo.spec
@@ -1,4 +1,4 @@
-%global gitrev d9bed0d
+%{!?gitrev: %global gitrev d9bed0d}
 # gitrev is output of: git rev-parse --short HEAD

 %if 0%{?rhel} != 0 && 0%{?rhel} <= 7

allows one to build librepo RPMs in Mock more easily than running make_rpm.sh in Mock (which requires copying files to and from the chroot and installing all the dependencies):

GITREV=`git rev-parse --short HEAD`
utils/make_tarball.sh "$GITREV"
mock --resultdir=. --define="gitrev $GITREV" --buildsrpm --spec librepo.spec --sources .
mock --resultdir=. --define="gitrev $GITREV" *.src.rpm

Also make_rpm.sh can get rid of the sed but I guess you still want to update the spec file with the new GITREV.

It will help us to build librepo nightly builds.

Let me know if there is any problem/ugliness.

So, we no longer build librepo in Mock so it's not such a pain. We now build just SRPMs and upload them to Copr. But unless you provide a script for building a SRPM (which also modifies GITREV), this change would still simplify our script (we could get rid of the sed).

Thank you. I don't see a change in the spec file so I hope you don't forget to apply the patch above. Otherwise, this would just break your workflow.
(But since you have already provided the script for SRPM building, we don't need this pull request any more. So, it's up to you whether you change the spec file or revert this commit.)

I will change the spec in Fedora, but before that, I want to apply few other patches and release a new minor version of Librepo. Stay tuned.

Rawhide build is ready => New spec is available in distgit (just for rawhide so far):

I just wanted to be sure that I did not break your workflow. Thanks again!

Actually, we build RPM only from master so we don't need any spec update in the other branches. But of course, make_rpm.sh wouldn't work for you unless you do the change...
(OK, we didn't but now we do :) )
