# How to maintain mock in OBS for SUSE

Note that mock requires two packages: mock and mock-core-configs

## Updating mock

You can find prebuild tar files here: https://github.com/rpm-software-management/mock/releases/

Mock requires tito[1] to be build directly from git. Since tito is not
currently built for SUSE, the prebuild packages from upstream can be used.

To download a new version of the package, you need to edit the "Version:"
value in mock.spec and run the following command:

```
osc service manualrun
```

## Keeping spec file up-to-date

Currently the .spec file is only being maintained in OBS and therefore has to
be manually updated. You can see the diffrence between OBS and upsteam by running:

```sh
# Note that the version might have changed
tar -xf mock-5.0.tar.gz
# You can also use vimdiff for nice visuals
diff ./mock-5.0/mock.spec mock.spec
```
