Description of problem: Graphviz has a distroagnostic src.rpm for el[67],fc2[3456] but COPR downloads the same src.rpm 6 times Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. copr-cli build graphviz http://john.ellson.com/copr/graphviz-2.39.20161012.1437-1.src.rpm 2. 3. Actual results: src.rpm downloaded 6 stimes Expected results: src.rpm downloaded 1 time Additional info:
Stealing the bug report to make it a bit more general. This becomes extremely important WRT mock-scm/tito builds; where not only download happens multiple times, but also docker container (doing mock --srpmbuildm thus installing minimal buildroot) happens N-times, I guess in all cases this happens on "dist-git" machine (not on builders) so this causes huge load.
Looks like to OOM bug 1412658 is related.
Fixed by https://pagure.io/copr/copr/pull-request/70 and deployed to production.
