Jazz SCM equivalent to CVS modules

0
Tom Frauenhofer (1.3k●5●84●35) | asked Feb 05 '08, 5:38 p.m.
Hi there

Using CVS over the years I've noticed that my team and others, often use
a CVS 'module' definition to work with a subset of a given CVS project.

For example, my team does porting work for a large existing product. We
load the entire product source tree (> 1.2Gig) into CVS. Throughout the
development project, we need to work with a much smaller (fixed) subset
(say only 300MB) of that tree. We define a CVS 'module' that includes
only the portion of the source that needs to be worked on so that
developers need not checkout gigabytes of data that they mostly never use.

After that long-winded description ...

1) is there any equivalent feature in the Jazz SCM

and if not

2) do teams using the Jazz SCM ever face this need see a 'subset' view
of their code ?

Cheers
Dave

You would use a Jazz SCM "component" to partition your source tree into
separate pieces.

As Geoff says, components are the way to go. But our granularity doesn't stop there. When you're loading a component, you can choose which root folders should be copied to your local disk.

As Geoff said, components are the first level of decomposition, but in
reality many projects already have a directory structure that they don't
want to split or refactor. There are a couple of things happening to
support finer grain loading that are being discussed in

https://jazz.net/jazz/web/projects/Jazz%20Project#action=com.ibm.team.workitem.viewWorkItem&id=42933

At a minimum we will support loading at any folder level for 1.0, a P2
is to remember this as you can with CVS modules or SVN externals.

Hope this helps.

Thanks to everyone who replied.

Componentization seems the right thing to do and I'm looking at that now.

The 1.0 support to select root folders is interesting ; is this likely
to surface in a milestone release before GA ?
