Recipes to build ALICE SW

Guidelines for commit messages

Keep the first line of the commit below 50 chars
Leave the second line empty
Try to keep the lines after the third below 72 chars
Use some imperative verb as first word of the first line
Do not end the first line with a full-stop (i. e. .)
Make sure you squash / cleanup your commits when it makes sense (e.g. if they are really one the fix of the other). Keep history clean.

Example:

Fix issue in Geant4

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim
veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea
commodo consequat.

Guidelines for contributing recipes

Keep things simple (but concise).
Use 2 spaces to indent them.
Try avoid “fix typo” commits and squash history whenever makes sense.
Avoid touching $SOURCEDIR. If your recipe needs to compile in source, first copy them to $BUILDIR via:

rsync -a $SOURCEDIR ./

Guidelines for handling externals sources

Whenever you need to build a new external, you should consider the following:

If a Git / GitHub mirror exists, and no patches are required, use it for the
package source.
If a Git / GitHub repository exists and you need to patch it, fork it, decide a
fork point, possibly based on a tag or eventually a commit hash, and create a branch
in your fork called alice/<fork-point>. This can be done with:
```
git checkout -b alice/<fork-point> <fork-point>
```
patches should be applied on such a branch.
If no git repository is available, or if mirroring the whole repository is
not desirable, create a repository with a master branch. On the master
branch import relevant released tarballs, one commit per tarball. Make sure
you tag the commit with the tag of the tarball. E.g.:
```
git clone https://github.com/alisw/mysoft
curl -O https://mysoftware.com/mysoft-version.tar.gz
tar xzvf mysoft-version.tar.gz
rsync -a --delete --exclude '**/.git' mysoft-version/ mysoft/
cd mysoft
git add -A .
git commit -a -m 'Import https://mysoftware.com/mysoft-<version>.tar.gz'
git tag <version>
```
In case you need to add a patch on top of a tarball, create a branch with:
```
git checkout -b alice/<version> <version>
```
and add your patches on such a branch.
Do not create extra branches unless you do need to patch the original sources.

Moreover try to keep the package name (as specified inside the recipe
in the package field of the header) and the repository name the same,
including capitalization.

Some instructions for working with a VM from CERN openstack

Assuming the user has read the openstack instructions and created a virtual machine.

CC7 – x86_64

on lxplus, login to your newly created virtual machine with your key: ssh -i .ssh/yourkey [email protected]
create your user: adduser yourUserName, passwd yourUserName, usermod -a -G wheel yourUserName
logoff and logon with your user

- sudo yum group install
