Subject [jira] Created: (IVY-1134) Incremental Resolve
Date Tue, 06 Oct 2009 12:47:31 GMT
Incremental Resolve
-------------------

                 Key: IVY-1134
                 URL: https://issues.apache.org/jira/browse/IVY-1134
             Project: Ivy
          Issue Type: Wish
          Components: Ant, Core
            Reporter: Jon Schneider
            Priority: Minor


I am trying to integrate an Eclipse Zest (GEF) Ivy resolve visualizer into IvyDE to help our
developers visualize the eviction process and to see how transitive dependencies were brought
into the classpath.  What started out as a visualizer is now being considered as a type of
editor as well.  Of course, if we edit a node visually (whether it be changing a version,
excluding a node, toggling the transitive attribute, etc.), we have to perform a resolve against
the whole ivy file associated with that visualization (which may not be quick).  I want to
get some opinions on an incremental resolve feature, which would somehow compare the cached
resolve file with the changing ivy file and resolve just the delta.

So just brainstorming, here are my thoughts:
- persist a copy (in the cache) of relevant pieces of the ivy file whenever a resolve is performed
so that the file can be compared on a subsequent resolve.
- we can pretty easily resolve just the particular dependencies that change, and the results
could only have two impacts on the rest of the tree stemming from:
## evictions
## exclusions

WDYT?
