Line 10: Line 10:
This should provide an overview of the issue/functionality/change proposed here. Focus here on what will actually be DONE, summarising that so that other people don't have to read the whole spec. See also CategorySpec for examples. Eucalyptus, as part of the Ubuntu Enterprise Cloud, needs to move to main to be properly supported by Canonical. That means that all runtime and build-time dependencies (and all dependencies of the dependencies) must also move to main. This specification tracks which packages will need to move to main and efforts made to reduce the total number as much as possible.
Line 14: Line 14:
This section should include a paragraph describing the end-user impact of this change. It is meant to be included in the release notes of the first release in which it is implemented. (Not all of these will actually be included in the release notes, at the release manager's discretion; but writing them is a useful exercise.)

It is mandatory.		 Eucalyptus is now part of the Ubuntu "main" repository, and fully supported by Canonical.
Line 20: Line 18:
This should cover the _why_: why is this change being proposed, what justifies it, where we see this justified. Eucalyptus is currently in universe, together with most of its Java library dependencies. Since Eucalyptus is part of the Ubuntu Enterprise Cloud product, it needs to be properly supported by Canonical, which means move to the "main" repository. However, packages in "main" also need to have all their runtime and build-time dependencies in "main" as well. Java software in general heavily makes use of other Java libraries, so this quickly snowballs into a large number of packages to move to main. Furthermore, there isn't so much Java-based software in main already (OpenOffice.org, tomcat6) so even some basic Java libraries need to be moved.
Line 24: Line 22:
 * Dave has been trying the UEC technology preview in 9.04 and aims to deploy UEC with the 9.10 release. As it will no longer be a technology preview, it needs to be properly supported.
Line 26: Line 26:
This spec does not take care of any other non-Java MIR that Eucalyptus may need. iscsitarget for example could be a new 1.6 dependency, and it is in universe currently.

Some hacks (like duplicating some greedy source packages to avoid bringing lots of unnecessary build dependencies) are worth the trouble if they save a significant amount of packages. However Debian doesn't care about keeping the number of dependency packages small, so those hacks don't really make sense from a Debian perspective.

=== Avoid packages difficult to maintain ===

 * Large software stacks
   * JBoss (pulled through Hibernate)
   * Glassfish (pulled through glassfish-javaee and glassfish-toplink-essentials, used as build-deps)

=== Proposed actions for package number reduction ===

 * Use a specific eucalyptus-javadeps with hibernate/ehcache/spring: saves 60+ packages
 * Remove dependency from libclassworlds-java -> maven-ant-helper: saves 8+ packages
 * Avoid dependencies on Glassfish packages, use geronimo-specs-* instead

=== Resulting list (without those from RefactorEucalyptusJavadepsSpec) ===

package* denotes a new package in karmic
-package denotes a potentially avoidable package

This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:

=== UI Changes ===

Should cover changes required to the UI, or specific UI that is required to implement this

=== Code Changes ===

Code changes should include an overview of what needs to change, and in some cases even the specific details.

=== Migration ===

Include:
 * data migration, if any
 * redirects from old URLs to new ones, if any
 * how users will be pointed to the new way of doing things, if necessary.		 === Create new eucalyptus-javadeps ===

Create the specific eucalyptus hibernate libraries, containing the subset of hibernate needed for Eucalyptus and not all the JBoss hooks the libhibernate3-java package contains. Same for ehcache and Spring.

Those should be shipped as the new "eucalyptus-javadeps" package (which is kept to include all the non-standard libraries required by Eucalyptus).

=== Implement other hacks ===

All the other number-reducing hacks should be implemented:

 * Remove dependency from libclassworlds-java -> maven-ant-helper: DONE
 * Remove jmock and libconcurrent dependency on kaffe

=== Determine final map of MIR, split into sets ===

The final dependencies should be determined and splitted into sets that can be handled separately.

==== Current status ====
 * 99 packages which would need to move to main.
 * Java in main is currently driven by OpenOffice. Tomcat6 is there, but has few dependencies.

==== Future ====
 * Eucalyptus version for Karmic should have fewer dependencies anyway from upstream refactoring.

==== How can the number of build/runtime dependencies be reduced? ====
 * Get rid of anything not necessary
  * Geronimo spec packages (already provided by glassfish-j2ee)
 * Move parts into Eucalyptus code
 * Refactor packages (e.g. hibernate pulls in a lot of stuff)
  * Requires multiple source packages or only to promote some resulting binaries to main.
    (doko recommends duplicating the source package and documenting it)

==== What could be expected to be refused inclusion to main ====
 * Active upstream criteria
  * Annogen
  * OpenSAML
  * WSS4J?
 * Known to be insecure
  * Nothing obvious
 * Partial builds (because of non-free dependencies)
  * Mule
  * We don't really care

==== Size issues (adding to default CD) ====
 * GWT is 6MB of binary
  * 1.6 should be more granular and work with existing java packages more
 * JRuby is 3MB
  * Just be a build-time dependency of GWT
 * libjgroups-java, 3MB. Not needed ?
 * glassfish-toplink-essentials, 2.4MB, comes from hibernate
 * Avoiding JDK would save about 50MB of CD space
 * Avoiding GCJ would save about 20MB

==== Can we use the new Spring packaging from Debian? ====
 * Not included yet in Debian, but work is underway
 * Might make too hard choices for us ? Testing from Eucalyptus side needed.

==== Safety net ====
 * Keep a eucalyptus-javadeps package to drop in any problematic parts which can't be fixed (hibernate?).
  * One tiny part of Drools

==== Action Summary ====
 * Which Eucalyptus version we'll use in Karmic and its dependencies?
 * Can we use Spring from Debian?
 * What can we do to reduce Hibernate size?
  * Will it be acceptable to move JBoss to main?
 * JDK dependency investigation
 * Ask Colin about blacklisting for the server seed only to solve GCJ issue
 * Once it's known what is required, start preparing/filing MIRs to avoid a last minute panic.

Summary

Eucalyptus, as part of the Ubuntu Enterprise Cloud, needs to move to main to be properly supported by Canonical. That means that all runtime and build-time dependencies (and all dependencies of the dependencies) must also move to main. This specification tracks which packages will need to move to main and efforts made to reduce the total number as much as possible.

Release Note

Eucalyptus is now part of the Ubuntu "main" repository, and fully supported by Canonical.

Rationale

Eucalyptus is currently in universe, together with most of its Java library dependencies. Since Eucalyptus is part of the Ubuntu Enterprise Cloud product, it needs to be properly supported by Canonical, which means move to the "main" repository. However, packages in "main" also need to have all their runtime and build-time dependencies in "main" as well. Java software in general heavily makes use of other Java libraries, so this quickly snowballs into a large number of packages to move to main. Furthermore, there isn't so much Java-based software in main already (OpenOffice.org, tomcat6) so even some basic Java libraries need to be moved.

User stories

  • Dave has been trying the UEC technology preview in 9.04 and aims to deploy UEC with the 9.10 release. As it will no longer be a technology preview, it needs to be properly supported.

Assumptions

This spec does not take care of any other non-Java MIR that Eucalyptus may need. iscsitarget for example could be a new 1.6 dependency, and it is in universe currently.

Design

We need to try to keep the number of packages as small as possible in order to avoid MIR team overload. Some hacks (like duplicating some greedy source packages to avoid bringing lots of unnecessary build dependencies) are worth the trouble if they save a significant amount of packages. However Debian doesn't care about keeping the number of dependency packages small, so those hacks don't really make sense from a Debian perspective.

Avoid packages difficult to maintain

  • Large software stacks
    • JBoss (pulled through Hibernate)
    • Glassfish (pulled through glassfish-javaee and glassfish-toplink-essentials, used as build-deps)

Proposed actions for package number reduction

  • Use a specific eucalyptus-javadeps with hibernate/ehcache/spring: saves 60+ packages

  • Remove dependency from libclassworlds-java -> maven-ant-helper: saves 8+ packages

  • Avoid dependencies on Glassfish packages, use geronimo-specs-* instead
