dgroc for ''Daily Git Rebuild On Copr''.

copr is a build system made publicly available to Fedora contributors and allowing to provide package repository for packages that are not or cannot be part of the standard Fedora repositories. There are multiple reasons a package is allowed in copr but not in the standard repositories, for examples:

• bundled libraries in the sources that have not been cleaned
• unstable version
• version introducing too many changes to be introduced to a stable Fedora release
• packages that are in the process of being integrated into Fedora but have not yet been approved

The use-case for dgroc is the second point on this list: unstable version.

I know some of us out here are crazy testers and for two projects I was interested in having daily builds, this allows easy install/update (just run yum/dnf) and easy testing.

What dgroc does is providing an easy way to automatically build packages on copr from a git repository.

It works fairly simply:

• Create a ~/.config/dgroc file and include in it some basic, generic information that will be needed either to update the spec file, make the source rpm available or build on copr:

[main]
username = me
email = my_email@example.com
copr_url = https://copr.fedoraproject.org/
upload_command = cp %s /var/www/html/subsurface/
upload_url = http://my_server/subsurface/%s
#no_ssl_check = True # no longer need now that copr has a valid ssl cert

• Then for each project you have to define at least three information, for example for subsurface:

[subsurface]
git_url = git://subsurface.hohndel.org/subsurface.git
git_folder = /tmp/subsurface/
spec_file = ~/dgroc/subsurface.spec

Eventually, you can specify a patch_files argument that will be a comma-separated list of patches that are need to build the project.

All what dgroc does from there is:

• clone the git repo if it is not already in the filesystem
• run a git pull to get the latest changes
• generate a new tarball (in the rpm %_sourcedir)
• update the spec file (release, source0 and changelog)
• generate the source rpm
• move that source rpm somewhere to make it available to copr (see the upload_command in the config file
• start the build on copr

I have been running dgroc for both subsurface and guake and it seems to work fine :)

The project isn't packaged yet but I thought I would announce it in case there are people interested in testing it and reporting bugs and RFE.

Hope you like it! :)
