Rebuild ceph with code coverage enabled

This script pulls the latest (already-released) build out of Brew and scratch-builds it with code coverage enabled. It generates a Yum repository and stores the artifacts on a remote server.

This allows QE to use these builds to get code coverage metrics.

Prerequisites

You will need the brewkoji package:

(Add the RCMTOOLS repository to /etc/yum.repos.d)

sudo yum -y install brewkoji

And the createrepo utility:

sudo yum -y install createrepo_c

Getting the code

Clone this repository:

git clone https://github.com/ktdreyer/build-ceph-coverage
cd build-ceph-coverage

Running

Ensure you have a Kerberos ticket:

kinit kdreyer

Run the script:

./rebuild.py

Results

This generates a new ceph-coverage RPM that you can download. This package ships the .cc and .gcno files in /usr/src/coverage/ceph.

To extract this RPM on an Ubuntu system (without installing it), you can run:

rpm2cpio path/to/ceph-coverage-12.2.5-1.noarch.el7cp | cpio -dium

This rpm2cpio ... | cpio -dium command will extract all the RPM's files into the current working directory.
