1. Tito
Miroslav Suchý Red Hat

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

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

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

5. 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

6. 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.

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

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

9. Project props $ cat ./rel-eng/tito.props [globalconfig]
default_builder = tito.builder.Builder
default_tagger = tito.tagger.VersionTagger

10. Package overrides $ cat ./selinux/oracle- selinux/build.py.props
[buildconfig]
builder = tito.builder.NoTgzBuilder
tagger = tito.tagger.ReleaseTagger
#builder = tito.builder.YourOwnBuilder

11. Tito config $ cat ~/.titorc RPMBUILD_BASEDIR=/tmp/spacewalk-build
KOJI_OPTIONS=-c ~/.koji/spacewalkproject.org-config build --nowait

12. 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.

13. 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.
