Maintainer's Guide

Creating a Release

1. create a github issue documenting significant release changes; review the commit log and closed issues to find them

This issue is to document functionality and features added to Omega_h since the #.#.# release (SHA1):

 - <feature> (issue/PR link)
 - <otherfeature> (issue/PR link)

2. apply the issue/PR label 'scorec-v#.#.#' to significant issues and PR that are part of the release
3. increase the Omega_h version # in CMakeLists.txt in the master branch
4. commit; include the issue # in the commit message

Omega_h version scorec-v#.#.#                                                                                                                                                                                                                                                                                                        
                                                                                                                                                                                                                                                                                                                             
see issue #<###>

5. push
6. create the tag git tag -a scorec-v#.#.# -m "Omega_h version scorec-v#.#.#"
7. push the tag git push origin scorec-v#.#.#

Updating the spack version

1. Create a branch of spack develop

git clone -b develop git@github.com:spack/spack.git 
cd spack
git checkout -b omegah#### 
git remote add scorec git@github.com:SCOREC/spack.git # add scorec remote for the new branch
source share/spack/setup-env.sh

2. Run spack edit omega-h to edit [omega-h/package.py](https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/omega-h/package.py) and change both the

• version number and
• commit hash which changes the Omega_h version (step 4 above)

3. Push the new branch

git push -u scorec omegah####

4. As of spack 0.21.0 (develop@abad16c) the following script will build and install pumi.

Create a file named testSpackOmegah.sh:

#!/bin/bash
