Common cases one product one package one repository pack everything in one tar.gz

Spacewalk 84 packages 10-20 new releases of packages each day plus testing rpms not possible to do it manualy create tar reproducible way

History Makefile - too much escaping, hard to read Tito - in python, plugins...

What Tito does? Tag new releases with incremented RPM version or release. Auto-generate spec file changelog based on git history since last tag. Create reliable tar.gz's with consistent checksums from any tag. Build source and binary rpms off any tag. Build source and binary "test" rpms off most recently committed code. Build multiple source rpms with appropriate disttag's for submission to the Koji build system

What Tito do? (cont.) Vary the way packages are built/tagged. Report on any diffs or commits messages missing since last tag. Build packages off an "upstream" git repository, where modifications in the "downstream" git repository will be applied as a patch in the source rpm. Manage all of the above for a git repository with many disjoint packages within it.

Quick start $ tito tag $ tito build --rpm --test $ tito build --release

Initialization $ tito init Create files: ./rel-eng ./rel-eng/packages ./rel-eng/tito.props

Builders Builder Includes functionality for a standard package build. Packages which require other unusual behavior can subclass this to inject the desired behavior. NoTgzBuilder Builder for packages that do not require the creation of a tarball. Usually these packages have source tarballs checked directly into git. i.e. most of the packages in spec-tree.

Taggers VersionTagger Standard Tagger class, used for tagging packages built from source in git. (as opposed to packages which commit a tarball directly into git). Releases will be tagged by incrementing the package version, and the actual RPM "release" will always be set to 1. ReleaseTagger Tagger which increments the spec file release instead of version. Used for: Packages we build from a tarball checked directly into git. Satellite packages built on top of Spacewalk tarballs.
