Application Installing (II)

I’ve been hacking more on the app-install framework. It’s now an independent project, with a tarball here.

What do the tools do?

$ app-install-create: creates the initial database, only used in the post section of the app-install package
$ app-install-add: adds data to the system database, used in repo packages
$ app-install-remove: removes data from the system database, used in repo packages
$ app-install-generate: generates the data for a desktop file, used when generating data from the distro helper

Now, the latter file is designed to be called from a distro specific helper, so for yum we do something like this:

$ –repo=rawhide –dist=./dist

This downloads all the rawhide packages that ship a desktop file, uncompress them, and extract the data from the desktop files. There’s a cache, so repeated runs of this don’t have to re-download all the data. This tool takes about 10 minutes to run when the download has completed.

This tools creates ./dist/rawhide-icons.tar.gz and ./dist/rawhide.sqldata which are designed to be shipped in a distro package file.

In a package file, for instance, fedora-app-install, the post action would be something like:

$ app-install-add –repo=fedora –source=/var/lib/app-install/rawhide.sqldata

and in the preun:

$ app-install-remove –repo=fedora

I’m inviting other distros to submit distro generate tools, and I’ll ship them in the tarball.

  1. David, I sincerely hope RH will give you a nice fat raise at the end of this year, considering how much rocking work you’re doing. Keep doing so, it’s greatly appreciated!

  2. Richard,
    Why not do this at rpm buildtime? Look for the dist file, then tuck the info you need into a specific known location in the package and into a Provides.

    Then your data could come along into Primary and there’s no extra md needed.

  3. @Seth: we can’t do this at build time. Putting 10Kb’s or binary data into an rpm provide is a horrible hack. What I’ve developed here was agreed with lots of other distros, and the mechanism is not yum and fedora specific.
