Subject [Report] Gump Report Q3 2010
Date Sun, 12 Sep 2010 04:53:21 GMT
Apache Gump is a cross-project continuous integration server.  It is
different from "usual" CI servers in that it expects the individual
project builds to succeed; its purpose is to check the integration of
a project with the latest code rather than a fixed version of the
project's dependencies.  If you want a more traditional nightly build
server, Gump is not for you.  Use Gump if you want to know when a
change in your dependencies breaks your project or when your changes
break other projects.

Gump's intention isn't so much to be a CI server but rather a vehicle
that makes people look beyond their project's boundaries and helps the
projects to collaborate.

Gump is written in Python and supports several build tools and version
control systems.  The Apache installation of Gump builds many ASF
projects and their dependencies.  It started in the Java part of the
foundation but also builds projects like APR, HTTPd and log4net.

== Summary ==

Big infrastructure changes, light development, no issues.

== Issues ==

There are no Board level issues.

== Community ==

The Gump project really consists of two parts, the code base for the
project and the ASF installations[1] running this code base to build
many ASF projects as well as some related projects.

The code base mostly does what its current users need so there isn't
much development going on at all.  No new committers have been added.

All ASF committers have write access to the metadata that configure
the ASF installations.  There are a few people contributing across all
projects and a few additional people maintaining the metadata of the
projects they are interested in the most.

No changes to the PMC.

== Development ==

While migrating to the new servers a few issues with Gump's database
access have been identified and fixed.  A new "builder" has been added
that removes the boilerplate code previously required when installing
a file to the local Maven repository.

We've managed to build a few projects that have been failing for a
long time in Gump - among them the ASF projects Forrest, Lucene,
Cactus and big parts of Cocoon.  We've also added builds for Solr,
Tika and PDFBox.

Some projects that have been failing for a long time and will likely
never become buildable again have been removed.  Also we've disabled a
few builds (mostly running some sort of tests) that caused Gump to
hang for an hour (Gump's timeout for build processes).

== Releases ==

The ASF installations of Gump work on the latest code base almost all
of the time.  The project is in a state of a perpetual beta.  There
have been no releases.

== Infrastructure ==

Our main machine vmgump has been replaced by a brand new virtual
Ubuntu machine.  The old database has been migrated to keep history.
Since the new machine now runs OpenJDK6 rather than an "official" Java
environment a few dependencies on Sun VMs have shown up in some
project's builds.

We used to have a Solaris zone which has now been replaced by a
FreeBSD jail.  The installation is working very well and we see almost
the same build failures and successes on FreeBSD as on Linux.

Many thanks to the infrastructure team for the support during the
migration - and for all the other stuff you do.

== Statistics ==

As of Sun, 12 Sep 2010 the ASF installations check out a bit less than
200 source trees (113 from the ASF repository) and try to build a bit
less than 600 "projects".  A complete Gump run takes more than nine
hours on vmgump and eight on the FreeBSD jail.
