goal
The goal is to build the following repository: https://buildlogs.centos.org/centos/7/cloud/ppc64le/openstack-pike/
Downloading the packages
Unfortunately, there is no corresponding SRPM directory to directly download the source packages. So I think I need to download all packages tagged with cloud7-openstack-pike-el7-build from CBS.
while read SRPM
do
echo "Downloading ${SRPM}"
((TRIES=5))
while ((TRIES > 0))
do
cbs download-build --arch=src ${SRPM}
if [ $? -eq 0 ]
then
break
fi
((TRIES -= 1))
done;
done < <(cbs list-tagged cloud7-openstack-pike-el7-build --rpms --arch=src --inherit --latest-n=1)
Building the packages
The simplest way (although not the fastest) is to build them all with mockchain.
mockchain -r epel-7-ppc64le --tmp_prefix=mockbuild --localrepo=mock-repo --log=mockchain.log --recurse *.src.rpm
Unfortunately, they all do not build:
[hamzy@pkvmci853 ~]$ (SUCCESS=$(find ~/mockchain.pike/ -name success | wc -l); FAIL=$(find ~/mockchain.pike/ -name fail | wc -l); echo "${SUCCESS} packages built successfully and ${FAIL} packages failed")
473 packages built successfully and 71 packages failed
Some of the root packages needed are:
[hamzy@pkvmci853 ~]$ while read FAIL; do DIR=$(dirname ${FAIL}); grep --ignore-case --no-filename 'No Package found' ${DIR}/root.log | sed 's,^.*No Package found for ,,' | sort | uniq; done < <(find ~/mockchain.pike/ -name fail)
nodejs
etcd
python3-devel
python34-unittest2
python3-funcsigs
python3-pbr
python-oslo-i18n
python-oslotest
python-oslo-config
python-oslotest
Pulling in other, already built repositories, and building again:
[hamzy@pkvmci853 ~]$ rm -rf ~/mockchain.pike/mock-repo/results/epel-7-ppc64le/
[hamzy@pkvmci853 ~]$ (export ADDREPO="--addrepo=https://cbs.centos.org/repos/cloud7-openstack-common-release/ppc64le/os/ --addrepo=https://cbs.centos.org/repos/cloud7-openstack-common-candidate/ppc64le/os/"; cd mockchain.pike/; time mockchain -r fast-epel-7-ppc64le --tmp_prefix=mockbuild --localrepo=mock-repo ${ADDREPO} --log=mockchain.log --recurse *.src.rpm)
real 1135m20.712s
user 1760m16.636s
sys 163m49.094s
[hamzy@pkvmci853 ~]$ (SUCCESS=$(find ~/mockchain.pike/ -name success | wc -l); FAIL=$(find ~/mockchain.pike/ -name fail | wc -l); echo "${SUCCESS} packages built successfully and ${FAIL} packages failed")
510 packages built successfully and 31 packages failed
is a little better. The following packages fail to build:
[hamzy@pkvmci853 ~]$ while read FAIL; do A=$(dirname ${FAIL}); B=$(basename ${A}); echo ${B}; done < <(find ~/mockchain.pike/ -name fail)

However, a build of python-cradox-1.3.2-1.fc27.src.rpm results in:

python-falcon
python-falcon-1.0.0-4.el7.src.rpm will hang the mockchain/mock process during the build.
python-httplib2
python-httplib2-0.9.2-1.el7.src.rpm has a hardcoded python3 dependency in the spec file when CentOS uses python34. python-httplib2-0.9.1-2.el7.src.rpm has ifdefed python3 to not build.

Apparently CentOS does not use EPEL when building packages, so you can't use epel-7-ppc64le.cfg and instead a custom mock environment needs to be created.
python-mock
Has hardcoded python3 requires. However, CentOS uses python34.

python-oslo-config and python-stevedore
OpenStack has some pretty strict dependencies that are not coded into the RPM spec files. Building with a newer version of python-stevedore seems to fix this issue:
[hamzy@pkvmci853 ~]$ cat ~/mockchain.pike/mock-repo/results/epel-7-ppc64le/python-oslo-config-4.1.1-0.20170517115009.3290830.el7.centos/build.log

python-sphinxcontrib-programoutput and python-sphinxcontrib-websupport
Both of these rpms have circular dependencies! For example:
