latest compatible conflict manager
----------------------------------
Key: IVY-648
URL: https://issues.apache.org/jira/browse/IVY-648
Project: Ivy
Issue Type: New Feature
Components: Core
Reporter: Xavier Hanin
Assignee: Xavier Hanin
The conflict manager system in Ivy is not currently flexible enough to deal
with some complex compatibility issues in a dependency graph. Here is an
example:
#A;1.0-> { #B;[1.0,1.5] #C;[2.0,2.5] }
#B;1.4->#D;1.5
#B;1.5->#D;2.0
#C;2.5->#D;[1.0,1.6]
In this case, the current conflict manager system doesn't allow to end up with
a set of compatible dependencies (#B;1.4 #C;2.5 and #D;1.5), because it
requires:
- adding additional constraints when a dynamic version constraint is resolved
to an actual version
- restarting the resolution process with such additional constraints when a
compatibility conflict occurs
Adding these two features and a conflict manager leveraging those to handle
this use case would be a nice improvement to Ivy conflict management
flexibility.
