Sure The first column is the number of times a repo has been used on a individual builder The second column is the tag name that populates the buildroot The third column is the repo id each time koji runs a newRepo task the resulting repo gets a repo_id that koji uses to identify the repo in use for a given task. this way we can easily go back to a given repo to reproduce a build the fourth column is the host id each host in koji has a unique id. the result is that the the greatest bulk of repos are used once or twice on a given host and that we would get no benefit but a greater cost in caching minimal buildroots Dennis -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJUuE4sAAoJEH7ltONmPFDRZR8QAL+VCeF1VPI7WSc4Th+ZdvmR JQrEqJSud5y8gucuTyU2R+sYcLFTaZR2qcjWaPdzQS7XiIIhv68KlKbganq6/r4g bHEytdcG9mZXxV69Uojq7hbfpDvd0EJu6sKCAy/uz2fuOJt/mdvxld5nVIpHBvJH vd8j+XN6jFOjb3FTVCrW/gxXEKW2+1eA7XsECu+e7XS1rBNC04FkFlZEbK9thMoQ K0ICXhrOtLXaara7ZuC7afP+xBvuTHjUQiFWrUDPrCtPKZXiXjXfk0rRFfhY+VHO ZJP7OR/RkLQ3dDVgRnHsVTxu5He0XdVnrsGmnPBneS+ThH46HEfVTMOjs4dUVcbW EjSzsYlPhiHCBMOi21NPgBH0XhB6x/9mCi6NYUTCFHkP8OHLQTVtcbA37gp6weqh 0UEhHtnmPCC/cD0UbmOhRD4ac75RQAMLt8vQr98g2HHzsis30gW1/A6KlBxZvhe5 d0ESfQEp3o/ex1wsw/b3oVuI9fPSoYH/c9nU8yEqZhx9bP8CoSXmvgHxxRBooZgf /7Uc+jANIJx0vFL8BPPPOhgGhOGe1VsJpUZ4gIH5Ee+vmXMqQOa4rOcWTLlmUjUD t60DuORK0gQdiXh6sljpXnyDYcJXleDXqq89hztdnCtaN+pUQsPhzawTnibjDlTL 1mGTikF3qAVK2EPJtOTN =I42g -----END PGP SIGNATURE----- -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
