Hampus,

This is not really practical at this point in time. In 3.0, we do
provide a mechanism for clients to provide their own load mutator (i.e.
the code that writes the files and metadata to the local disk) but it is
still pretty heavy weight in the sense that you would need to make use
of SCM internals to make it work (and it is a lot of work to write a
mutator).

Having said that, it may be the case that there is a way to accomplish
what you want with what we currently have. Perhaps you can elaborate on
what you want your load logic to be.

Hi,

Im trying to intercept the workspace loading process but I cant
really find any extension points for that. I can see that there is an
implementation for ILoadRule which reads a file and figures out which
files/folders to checkout but I would like to have my own logic for
loading workspaces. Is this possible in some way?

Hi Michael,

What I want to do is to load a repository workspace containing a few projects and then based on Ivy information in those projects figure out the dependencies from different configurations and then load them from a binary repository into an EAR and perhaps a few supporting projects acting as containers for different classpaths.

Ive seen the way you do it with developer offerings but that seems quite specific for OSGI environments.

Hampus

Hampus,

It sounds like you may be able to write a script that uses the SCM CLI
to load the initial projects, analyze the Ivy information and then load
any additional projects.

There is no doc on the mutators as it is internal to SCM. As I indicated
in my previous post, the only practical way of achieving what you want
is to investigate scripting your load using the SCM command line client.

Ok, I understand what youre saying but our developers have become kind of familiar to a tight integration between our current "SCM" (CVS and a lot of XML) and RAD. They can synchronize through participants and the synchronize view with different Ivy repositories. I think that they would be disapointed if we went back to a scripting solution without real integrated UI etc.

What about connectors? Could we write a connector that would synchronize the workspace with an Ivy binary repository?

WRT the ClearCase Connectors, the SCM Synchronizer machinery used by the
ClearCase Synchronizer does transfer data, but it does so directly
between a stream in the RTC repository and the semantic equivalent of a
stream in the other repository (bypassing the file system altogether,
for efficiency and to avoid file system peculiarities such as whether or
not symlinks are supported), so that wouldn't help you here. The
Subversion Connector uses completely different underlying machinery, so
I'll defer to Michael on whether the Subversion Connector might have
some application here.

Cheers,
Geoff

Hampus,

I would recommend that you open an enhancement request against the RTC
Source Control component this. Make sure to include a description of the
use cases you require. Once we have a better understanding of the use
cases, we may be able to suggest some approaches with the existing API
or work toward adding support for them.
